| Abstract: | The intersection of Sustainability and Digital Transformation exemplifies the role of Artificial Intelligence in leveraging global efforts toward the United Nations' 17 Sustainable Development Goals (SDGs). We provide a systematic review of AI's role-specifically Machine Learning (ML), Deep Learning (DL), Natural Language Processing (NLP), and Computer Vision (CV)-in monitoring, modelling, and achieving targets across all 17 SDGs. The analysis is contextualized by two different approaches: the first relates to AI applications in scientific research, and the second explores how AI can be utilized to achieve the targets of an SDG. Regarding the former, it is demonstrated how AI-powered tools for sustainability tracking, human security analysis, and green workforce skills mapping contribute to the scientific research of the Ae4ria research network, a dynamic international scientific research network that pursues a multitude of environmental research goals and activities (Ae4ria.org). As for the latter, a detailed case study on SDG 7 (Affordable and Clean Energy) illustrates AI's technical capability in managing the complexity of modern power systems, using dynamic reserve dimensioning, optimization of continuous intraday trading strategies, and multi-agent reinforcement learning for computing economic equilibria in balancing markets. Yet, despite the breadth and high potential of AI in monitoring, assessing, and ultimately achieving the SDGs, we need to address the policy paradox presented by AI's rapidly growing environmental footprint, particularly the substantial energy demands and carbon emissions associated with data centers and large model training. This highlights the need for innovative policy instruments, such as "Green AI" incentives and governance frameworks, that can promote circular economies for digital infrastructures underpinning the development of AI. Realizing AI's transformative potential is ultimately contingent upon addressing critical economic, institutional, and ethical dimensions, ensuring that its deployment fosters an equitable and truly sustainable digital transition for all. |

| Abstract: | The Greek agri-food system faces mounting environmental, economic, and public health challenges driven by climate change, biodiversity loss, and a departure from traditional dietary patterns. This study uses the FABLE calculator to examine the potential impacts of transitioning toward the Mediterranean Diet (MD) under different scenario pathways. The FABLE Calculator is an integrated modelling tool for assessing sustainable food and land-use pathways under various scenarios including Shared Socioeconomic Pathways (SSPs). Our analysis for Greece highlights that adopting the MD could reduce agricultural greenhouse gas emissions in Greece by up to 46-60% by 2050.This occurs primarily through lower methane and nitrous oxide emissions from reduced livestock production and associated land-use change. Other key environmental benefits include enhanced biodiversity and improved land-use efficiency. The shift also delivers substantial health gains, lowering risks of cardiovascular diseases and diabetes while improving food affordability. However, our results also highlight significant economic trade-offs, including declines in production value and employment particularly within livestock-dependent sectors. Projected increases in production for crops does not compensate for losses in livestock production. Productivity improvements further accelerate emissions reduction and further reduce production costs but do not fully offset labor losses. The findings underscore the "double dividend" of dietary transitions-simultaneous climate and health benefits-whilst revealing key economic problems and evincing the need for complementary policies to ensure equity and resilience. Integrating dietary shifts into national climate, agricultural, and health strategies, supported by education, fiscal incentives, and social protection, can advance Greece toward a sustainable, healthy, and inclusive food system. But more effort is needed to match supply side measures to dietary changes, echoing very recent publications and case studies. |

| Abstract: | This study investigates the characteristics of global public interest in key search terms related to climate and energy, based on data from Google Trends across three thematically distinct but interconnected groups of search phrases for the decade 1/2015-12/2024. Each group was carefully selected to capture different aspects of the environmental discourse. The first group consists of 'Sustainability', 'Climate Change', and 'Global Warming', which serve as umbrella concepts for many subtopics with climate policy and physics. The second group, 'Greenhouse Gases', 'CO2 Emissions' and 'Carbon Emissions' reflects a better understanding of the climate drivers. And the third group consists of 'Renewable Energy', 'Fossil Fuels', and 'Nuclear Energy' addressing the major debate over how societies should power themselves while transitioning to a sustainable future. The analysis of Google Trends time series for these keywords and for "all categories", "science" and "news", i) reveals that public interest follows a strong biannual seasonal cycle for all of these climate-related terms with the peaks taking place in spring and autumn months ii) enables the identification and interpretation of various spikes over time iii) identifies the countries with the highest relative search activity for each keyword iv) examines the correlations in searches between these search terms. The understanding of people's interest and perceptions can be useful for the design, announcement and implementation of environmental policies. |

| Abstract: | In this study, we provide ex post empirical analysis of the effects of climate policies on carbon emissions at the aggregate national level, using a comprehensive database of 121 countries. Carbon taxes and emissions trading systems (ETS), and the overall stringency of climate policies are considered. We use dynamic panel regressions, controlling for macroeconomic factors (economic development, GDP growth, urbanisation and the energy mix). Higher carbon taxes and ETS prices reduce carbon emissions. An increase in carbon taxes by $10 per ton of CO2 reduces CO2 emissions per capita by 1.3% in the short run and by 4.6% in the long run. |

| Abstract: | Environmental externalities – uncompensated damages imposed on others – lie at the root of climate change, pollution, deforestation and biodiversity loss. Empirical evidence is limited, however, as to how externalities drive private decision making. We study one such behavior, illegal tropical forest fires, using 15 years of daily satellite data covering over 107, 000 fires across Indonesia. Weather-induced variation in fire spread risk and variation in who owns surrounding land allow us to identify how far externalities influence the decision to use fire. Relative to when all spread risks are internalized, we find that firms overuse fire when surrounded by unleased government lands where property rights are weak. In contrast, and consistent with the Coase Theorem, firms treat risks to nearby private concessions similarly to risks to their own land. Government sanctions, concentrated on fires spreading to populated areas, also deter fires, consistent with Pigouvian deterrence. |

| Abstract: | This report reviews the climate change performance of 70 high-, middle- and low-income countries assessed against the ASCOR framework in 2024. Collectively accounting for more than 85% of global greenhouse gas (GHG) emissions and 90% of global GDP, the country universe covers the key national players in the low-carbon transition. They are also the most relevant countries for investors to incorporate climate change considerations into their sovereign bond evaluations, as together they cover 75–100% of the major sovereign bond market indices. |

| Abstract: | The debate on environmental policy increasingly focuses on aligning private incentives with social objectives in imperfectly competitive markets. While traditional literature has centred on public-based mechanisms like taxes and subsidies, a growing strand emphasizes private-based mechanisms, particularly green consumerism, where consumer preferences can drive firms’ adoption of clean technologies. Recent game-theoretic analysis shows that consumers’ willingness-to-pay can lead to various market equilibria, from all-green to all-brown outcomes. This paper complements this analytical approach by developing an agent-based model (ABM) to study the dynamic evolution of a spatial market where firms, based on relative performance, decide whether to supply brown or green products to heterogeneous consumers. Our computational simulations confirm that all three market structures—all-brown, all-green, and mixed—can endogenously emerge depending on average green consumer preferences. Furthermore, we evaluate the effectiveness of three policy instruments: an environmental tax, a subsidy to green firms, and a subsidy to green consumers. We find that supply-side policies are more effective than demand-side subsidies. Specifically, an environmental tax ensures the fastest convergence to an all-green market, while a production subsidy is most effective at reducing the share of brown firms and consumers in mixed-market scenarios. By bridging game-theoretic insights with agent-based computational analysis, this paper provides a dynamic and policy-relevant perspective on the transition to sustainable markets. |

| Abstract: | In recent years, increasing attention has been given to the conservation of Posidonia oceanica, a vital Mediterranean seagrass species. This policy brief presents a review of the most recent scientific knowledge, along with ongoing efforts to protect and restore its meadows - primarily illustrated through research and experimental work carried out in France. P. oceanica meadows, often called the "underwater forests", form dense, leafy habitats that support rich marine biodiversity. Like their terrestrial counterparts, they provide shelter and food for numerous species, stabilise coastlines, and sequester significant amounts of carbon, contributing to climate change mitigation. Slow-growing and long-lived some clonal meadows are thousands of years-old, they are also highly vulnerable to human pressures such as anchoring, pollution, and coastal development. Protective measures include anchoring bans, eco-mooring systems, and marine protected area zoning, though enforcement remains uneven across regions. Innovative financing mechanisms, including blue carbon credit schemes, are emerging to support long-term conservation and sustainable local livelihoods. |

| Abstract: | Exploiting three decades of detailed regional data for Germany, we find that when the Green Party is successful at the polls, local hazardous emissions decline. The level of political representation matters, too. Green politicians’ gaining influence at county level is followed largely by a decline in air pollutants that have an immediate adverse health effect. In contrast, when the Green party joins the state government, only greenhouse gas emissions that affect the welfare of future generations via climate change decline. The primary mechanism to achieve lower emissions appears to be a reduction in output, rather than more efficient energy use. JEL Classification: D72, Q53 |

| Abstract: | This paper introduces a novel methodology to enhance the granularity of Inter-Country Input-Output (ICIO) tables. While our general methodology can be applied to any products of interest, we show that the well-documented distortions caused by sectoral aggregation in ICIO tables are particularly pronounced for products with a low substitutability, such as those essential to the green transition (e.g. electric batteries, rare earths). We therefore apply our framework to construct a disaggregated ICIO table that singles out 129 products essential to the energy transition. We then simulate a hypothetical scenario of an East-West supply chain decoupling in green products through a multi-country multi-sector model calibrated with our tailored disaggregated ICIO table. Results reveal substantial economic costs: welfare losses reach 3% and trade between blocs contracts by 20%, even when accounting for trade diversion through neutral countries. We finally quantify how the green supply chain decoupling increases the intensities of greenhouse gas emissions, highlighting how trade barriers on green sectors affect both economic efficiency and climate objectives.

| Abstract: | To reach policy targets of reducing farm greenhouse gas emissions (GHGs) and to improve farmland biodiversity, additional finance is needed outside of traditional government programmes. One method of encouraging private finance to support biodiversity enhancements and GHG reductions on farms is through insetting, that is crediting farmers for their on-farm environmental actions within the agrifood value chain. In this study we explore the potential of carbon and biodiversity insetting by engaging with stakeholders to co-design the tools required to support robust and transparent on-farm sustainability improvements. Monitoring, reporting and verification (MRV) platforms have been developed to assess soil carbon, biodiversity and assess the carbon footprint of farms. FarmCredit works with two leading MRV technology companies to assess soil carbon, biodiversity habitat extent and the carbon footprint of participating farms. In conjunction with stakeholders in agri-finance, food processing, and government, this study co-designs an action-based insetting payment system that farmers can realistically engage with, and that agri-food corporates and government bodies want to invest in. Finally, we consult with stakeholders to develop policy frameworks to support carbon and biodiversity insetting in the agri-food value chain. The tools developed in FarmCredit can be applicable to dairy and other sectors of agriculture and land use within the agri-food value chain. The development of robust insetting sustainability programmes within the agri-food value chain also has the potential to drive down emissions in the Agriculture, Forestry, and Land Use (AFOLU) sector and may encourage carbon sequestration in agricultural soils or biomass. Robust insetting may also prevent agri-food sector carbon credits from carbon sequestration or avoided emissions from being utilised as offsets by other GHG emissions intensive sectors. |

| Abstract: | Climate change is already exacerbating water scarcity issues, particularly in vulnerable regions such as the Mediterranean. In this context, agricultural adaptation measures are essential to ensure food security and sustainable agriculture. This research focuses on the prioritization and socioeconomic assessment of adaptation strategies for agriculture in the Arroyo de la Balisa sub-basin (Segovia, Spain). A participatory multi-criteria approach was conducted with 41 local stakeholders, including public administration, agronomic engineering companies, farmers, livestock producers, environmentalists, and experts, who ranked 14 adaptation measures under current and future scenarios. Subsequently, a structured questionnaire collected detailed insights from local farmers regarding socioeconomic impacts and implementation barriers for the eight prioritized measures. Key findings indicate that, despite their considerable potential benefits, irrigation-related measures such as modernization and expansion are hindered by high costs and significant implementation barriers. Conversely, cover crops for woody crops and crop rotation with soil-improving species emerged as the most feasible options due to balanced cost-benefit perceptions among farmers. The participatory approach adopted, involving active validation by local actors, provided context-specific insights and enhanced the practical relevance and acceptance of results, facilitating targeted policy interventions to foster climate resilience in Mediterranean agriculture. |

| Abstract: | As carbon regulations continue to tighten, a key question emerges: should firms proactively adopt environmental responsibility to effectively manage the risks and opportunities presented by these heightened carbon policies? This study assesses the effect of carbon initiatives (e.g., Emission Trading System and carbon tax) on firms' financial performance, moderated by the environmental responsibility of firms, a crucial aspect that has been largely overlooked in the literature, especially in the context of indirect carbon emission-intensive sectors. By analyzing data from global Real estate Investment Trusts (REITs) spanning from 2003 to 2022, the study reveals that REITs with better environmental performance are more resilient against carbon policy shocks. This reflects the importance of firms' environmental commitment as a protective measure for investors, particularly when confronted with new environmental policies. The findings also align with Porter's (1990) early movers assertion that firms that adopt advanced environmental standards early can gain first-mover advantages, ultimately enhancing their financial performance. This suggests that firms should prioritise sustainability, as those who are better equipped are more likely to succeed in the swiftly transitioning low-carbon economy of the future. This also emphasizes the significance of incorporating firms' environmental commitment into the analysis. The implications of these findings are profound and have been thoroughly discussed. |

| Abstract: | This paper focuses on the economic and environmental implications of energy-efficient building practices in existing structures. It starting point is the significant impact of the construction sector on global greenhouse gas emissions and energy consumption, emphasizing the urgent need to address climate change mitigation efforts. An important aspect thereby is the lifecycle assessment of buildings, dividing the process into distinct phases such as construction, usage, deconstruction and recycling to analyze environmental impacts, costs, and resource efficiency. By evaluating different aspects like building materials, construction techniques, and energy usage, mainly effected by heating and ventilation systems, the paper aims to provide insights into enhancing energy efficiency and reducing emissions in building practices. The paper incorporates technical and economic perspectives to explore the balance between environmental sustainability and financial considerations in building modernizations. Through empirical analyses using data from the Building Cost Information Center of the German Chamber of Architects (Baukosteninformationszentrum der Deutschen Architektenkammer - BKI), the paper aims to determine the economic value by incorporating both, a brief theoretical overview contrasted by an analysis of measures that have been carried out. The research addresses the challenges associated with retrofitting existing buildings, considering factors like varying structural conditions, historical preservation requirements, and financial incentives for property owners. In conclusion, this paper contributes to advancing knowledge in the field of sustainable construction practices by integrating technical analyses with economic evaluations and by identifying the interplay between energy efficiency, environmental impact, and financial viability. |

| Abstract: | Farm-level climate adaptation is necessary to mitigate and prevent climate change impacts and thereby build resilience within farming communities. This exploratory qualitative study aimed at examining farm-level climate resilience. Notably, we explored experience and impacts of climate change faced by Irish farmers, and identify farm-level strategies towards climate adaptation and factors affecting their implementation. Qualitative data was gathered from farmers and farm advisors to capture different perspectives. The data was analysed through thematic analysis. The results showed that farmers experienced a range of environmental, work organisation, social, and economic climate impacts, which were interconnected. Farmers responded by adopting reactive and proactive adaptation strategies, with the aim of mitigating impacts and/or reducing vulnerability to future weather events. The implementation of these strategies was influenced by a series of economic, environmental, social, and institutional factors. Overall, the results highlight the need for continued support for farmers and agricultural advisors to enable climate adaptation. |

| Abstract: | With over fifty percent of its total exports consisting of petroleum and coal, Colombia remains highly vulnerable to both global and domestic energy transitions. With the aim of fostering policy dialogue, this book assesses these long-term macro-financial risks, opportunities and vulnerabilities as it contends with the global shift towards a low-carbon economy and the domestic emission reduction initiatives outlined in the latest Nationally Determined Contribution (NDC). To this end, the authors develop an empirical macroeconomic Stock-Flow model of Colombia (GEMMES - General Monetary and Multisectoral Macrodynamics for the Ecological Shift) to analyze the implications of various global and domestic transition scenarios. The model distinguishes itself from existing literature by its strong focus on the financial system and the explicit feedback loops between the real and financial sectors of the economy. The authors present a comprehensive macroeconomic analysis of the complex interplay between the transformation of the real economy and the dynamics of the financial sector and public balances. The effective development and implementation of the GEMMES model for Colombia have been achieved through a strong collaboration between key domestic institutions, such as the National Department of Planning (Departamento Nacional de Planeación), the Ministry of Finance (Ministerio de Hacienda y Crédito Público), the National University of Colombia (Universidad Nacional de Colombia), and the GEMMES modelling team at the French Development Agency (Agence Française de Développement). The findings from this collaborative effort highlight the importance of coherent industrial, monetary, and fiscal policies in managing the transition effectively in Colombia. Both to mitigate adverse effects and to accelerate the country's socioeconomic development path, the transition represents an opportunity to diversify the productive structure, integrate into the value chains of new green industries, strengthen public infrastructure, generate quality jobs and reduce dependence on natural resource-based industries. |

| Abstract: | After nearly 50 years of reform, the Chinese economy experienced exponential growth at the expense of the environment. China's air pollution has reached critical levels, necessitating an urgent transformation. The Chinese government has proposed an ambitious goal of carbon neutrality by 2060. Following this ambitious environmental goal, regulators heavily promoted green finance as a key to addressing the funding gap for sustainable infrastructure. The rise of green finance vehicles, with the goal of incentivizing social capital to invest in formally un-attracted sustainable infrastructure and closing the financing gap for green transformation, has gained enormous practical popularity among major sustainable infrastructure developers. While green finance instruments have been extensively studied, the comparative effectiveness of different green finance instruments in attracting social capital remains unknown. This study aims to investigate the relative comparative advantage of the most prominent green finance instrument and the most innovative green finance instrument, namely green bonds and green Real Estate Investment Trust, and to assess their relative effectiveness in increasing social capital's willingness to invest. This study will significantly contribute to our understanding of green finance's effectiveness and inform better policymaking for sustainable urban development and carbon neutrality. |

| Abstract: | Responsible Property Investing (RPI) is integrating environmental and social factors into real estate investment decisions. This study examines the dual realities of RPI: its potential as a driver of green transformation and the prevalence of greenwashing practices that undermine sustainability efforts in cities as well as the environmental, social, and governance (ESG) policies of companies. By analyzing survey data from 2024 collected from the 60 largest municipalities in Poland and over 50 major commercial real estate investors (including companies listed on the stock exchange), this research identifies both the enablers and the barriers to implementing RPI in practice. The findings show a gap between the aspirations of RPI and its implementation, with both parties struggling to align long-term strategies and goals of the other side, underscoring the critical need for improved dialogue and harmonized policy frameworks that can ultimately bridge this divide and advance sustainable real estate practices on a broader scale including not only profit, but also environmental and social goals. This research provides recommendations for property investors, emphasizing the need for clear definitions, robust regulations, and enhanced stakeholder engagement to foster the green transformation of cities instead of greenwashing. By critically assessing Poland's experiences, this study contributes to the general discussion on achieving urban sustainability through responsible investment practices and furthermore ESG. |

| Abstract: | Natural Language Processing (NLP) has emerged as a transformative tool for sustainability policy analysis, enabling automated assessment of vast policy corpora at previously impossible scales. This paper presents a production-ready multi-method NLP system for detecting and quantifying six FABLE National Commitments (Biodiversity, Climate Mitigation, Food Security, Economy, Fertiliser Use, and Water Management) in European Green Deal policy documents. Our system employs four complementary NLP techniques-enhanced keyword analysis, spaCy-based phrase detection, TF-IDF semantic similarity, and syntactic pattern matching-with conservative evidence-based scoring to ensure analytical reliability. Through rigorous validation and systematic elimination of false positives, the system achieves over 90% reduction in erroneous classifications compared to baseline approaches. We demonstrate the system's capabilities through analysis of 42 European Green Deal policy documents, including detailed case studies of the REPowerEU Energy Plan and EU Energy Integration Strategy. The system processes documents at 1.4-3.9 seconds per file with 100% success rate, providing transparent evidence trails with keyword counts, context excerpts, and multi-method validation. Our work bridges the gap between sustainability science and computational methods, providing policymakers and researchers with reliable, scalable tools for evidence-based policy analysis aligned with the FABLE Consortium's integrated pathways approach to sustainable land-use and food systems transformation. |

| Abstract: | The financial industry has become increasingly entangled with environmental matters of concern, constituting the phenomenon of ‘green’ finance. In this Forum, we approach green finance as financial climate governance to highlight its claim on finance’s role as legitimate and capable steward of the planet’s climate. This claim to govern and its promise to achieve desirable environmental conditions have made green finance a crucial object of investigation. However, we observe a growing fragmentation of green finance research along various fault lines, such as levels of analysis, normative positions, or academic structures. Calling for reassembling green finance scholarship, we posit a need for more integrative approaches, motivating this Forum’s central question: what integrative moves across socioeconomic research can enhance our understanding and judgement of green finance? The Forum gathers three contributions focused on: (1) integrating macro- and micro-approaches in green finance studies; (2) examining the politics of green finance as knowledge contestations; and (3) confronting stasis in green finance by exploring researchers’ agencies, emotions, and normativities. By reassembling green finance scholarship through integrative moves, we suggest marking green finance as a shared concern and fostering collective perspectives to bring clarity and constructive critique to what has become a dominant pursuit in facing the socioecological crisis. |

| Abstract: | This paper discusses the attributes and design of alternative mitigation instruments for the industrial sector, their competitiveness and emissions leakage impacts, and supplementary measures to address these effects. A quantitative analysis indicates, for selective countries, production cost increases under a $50 per tonne unilateral CO2 price in 2030 are 4-8 percent for steel, 20-30 percent for chemicals, and 30-35 percent for cement with leakage rates of 20-50 percent across these industries.

| Abstract: | Under the current climate change scenarios, Switzerland's real estate sector faces important exposures to natural hazards, with floods alone causing over CHF 15 billion in damages over the past 50 years. Despite the rising urgency of climate risk management, research on Swiss Real Estate Funds (REFs) and their flood risk exposure remains limited. This study fills the gap by analyzing flood risks—specifically river and pluvial flooding—across REFs using two unique datasets: detailed portfolio holdings of over 9, 000 properties and granular climate-oriented flood risk data. Findings show that while less than 6% of properties are at flood risk, exposure is unevenly distributed. Large funds maintain fairly low flood risk, but several smaller funds exhibit significant vulnerabilities. Swiss REFs maintain the bulk of their properties of Cantons like Zürich and Vaud investments with minimal flood exposure, while holdings in Genève, Basel, and Ticino face heightened risks. Regression analysis reveals that funds investing near their headquarters benefit from local knowledge, reducing flood risks, while geographically diversified portfolios outperform concentrated ones in mitigating climate exposure. These insights underscore the need for Swiss REFs to prioritize climate risk assessment in their long-term strategies. Proactive diversification, integration of climate scenarios and consideration of anti-flood mechanisms will be crucial to building resilient portfolios in an era of escalating climate challenges. |

| Abstract: | Climate change is becoming evident in Sri Lanka due to increasing temperatures and changes in rainfall patterns. As a country with an agriculture-based economy, the impact of climate change on crop production threatens food security. The present study aimed to examine the symmetric and asymmetric effects of climate change on rice production in Sri Lanka. In this study, we used Autoregressive-Distributed Lag (ARDL) and Non-linear Autoregressive Distributed Lag (NARDL) models. Data for the period between 1952 and 2022 was compiled by the World Bank and the Department of Census and Statistics Sri Lanka. Estimated results were also validated using Fully Modified Ordinary Least Squares (FMOLS), Dynamic Ordinary Least Squares (DOLS), and Canonical Cointegration Regression (CCR). The results of the symmetric ARDL model indicate that temperature and cultivated land area have significant long-term effects on rice production. The results of the NARDL model show that positive and negative changes in climate variables have an asymmetrical long-run impact on rice production in Sri Lanka. Positive changes in temperature and rainfall have a significant negative impact on rice production. At the same time, negative changes rainfall has a significant and positive impact on rice production. Changes in cultivated land areas, both positive and negative, have a long-term significant impact on rice production. Policymakers must comprehend both the symmetric and the asymmetric effects of climate change on rice production and implement agricultural policies that promote sustainable agricultural development and to develop improved climate risk management strategies leading to ensuring food security in Sri Lanka. |

| Abstract: | In many countries around the world, water scarcity could become a macroeconomically relevant concern. As a key input into production processes (agriculture, power generation, and industrial use) and a common good, water resources risk being overexploited. Regressions with panel data for 169 countries between 1990 and 2020 show that, while water use is positively correlated with output, higher water scarcity is associated with lower gross domestic product growth and investment, and higher inflation. In contrast, water use efficiency is associated with higher gross domestic product growth and lower inflation. Climate scenarios show risks of much more severe water shortages in the future, threatening its sustainable use. This could impose higher costs on individual sectors and on the economy, reducing output and pushing up prices. Water availability and use could thus become an area for economists and central banks to monitor in the context of climate change, economic forecasting and monetary policy. |

| Abstract: | This paper examines the macroeconomic consequences of climate shocks in Paraguay, a small and open agricultural exporter that is highly exposed to droughts and floods. Utilizing a modified version of the World Bank’s Macro-Fiscal Model, the analysis integrates stochastic climate shocks drawn from external biophysical models to assess the impacts of extreme weather events such as droughts, heatwaves and floods on agriculture and livestock production and labor productivity in Paraguay. The findings reveal significant vulnerabilities in agricultural outputs and exports across a range of climate scenarios. The paper presents a comprehensive analysis across different climate scenarios ranging from mild to severe and quantifies the range of potential impacts on key economic indicators. |

| Abstract: | Climate change poses significant challenges to the productivity of the European agricultural sector, particularly in low-latitude regions such as the Mediterranean. The extent to which sectoral labour reallocation—shifting labour from agriculture to non-agricultural sectors—serves as an adaptation strategy to climate shocks remains an underexplored research question. This paper examines how weather variability affects inter-sectoral labour reallocation among agriculture, construction, industry, and services across 1, 149 European districts (NUTS3 level) from 1980 to 2022. In doing so, we also explore the extent to which weather-driven sectoral productivity shocks serve as a key mechanism. Leveraging this large and granular dataset, we employ flexible functional forms within a fixed-effects panel framework, where the impact of weather shocks is conditional on long-term climate. Unlike previous empirical research in climate economics, which primarily focused on inter-annual variations in average temperature, this study emphasizes the significant role of daily temperature variability. Temperature variability is particularly critical in warmer regions with low seasonal variability, which are more vulnerable to sudden temperature shifts or rainfall shocks. In hot regions with low seasonal variability—such as the Mediterranean—we find a robust adaptative response in the labour market, where workers shift from climate-sensitive agriculture to less affected sectors, such as industry and services. Interestingly, we also observe a labour reallocation effect in the opposite direction—from industry and services to agriculture—in the most cold and high-income districts. The heterogeneous impact of weather shocks on sectoral value-added growth across different climates appears to be a key mechanism driving this labour reallocation. |

| Abstract: | How should governments design climate policies in the presence of inequality, uninsurable risk, and fiscal constraints? To address this question, we develop a climate--economy model with incomplete markets and idiosyncratic labor-income risk, where Ricardian equivalence fails and optimal long-run capital taxes are positive, leading to important inter-temporal wedges. We analytically show that the optimal carbon tax equals the social cost of carbon (SCC) adjusted for fiscal distortions. Calibrating the model to the U.S., we show that these adjustments are quantitatively negligible: high levels of household inequality, income risk, and fiscal distortions do not, in themselves, justify lowering climate ambitions. Welfare gains under the optimal policy come almost entirely from efficiency and environmental amenities, with almost no effect on redistribution and insurance, and are fairly evenly distributed across households. |

| Abstract: | The property sector is faced with numerous regulations, some of which are based on the European Green Deal. At the same time, the data economy is not stopping at the property industry, leading to the adaptation and reorientation of processes and methods. However, this disruptive environment is also creating new opportunities, like for example assessing the 'smart readiness” of buildings. The digital economy is a key enabler of smart-ready buildings, driving energy efficiency, cost savings and sustainability. As smart technologies evolve, buildings will play an increasingly active role in energy optimisation, carbon reduction and the transition to a greener economy. The Smart Readiness Indicator (SRI) assesses a building's potential to contribute to energy efficiency in building operations, while providing a healthy and comfortable indoor environment, as well as potential grid flexibility. This paper explains the SRI, a simplified approach to determine the indicator in a cost-effective manner, and how it can be used to meet requirements in sustainable finance, ESG reporting, and green building certification. It is based on work carried out in the EU-funded easySRI project. The paper is intended for the following Themes: Theme G: Sustainable Real Estate Theme H: New Technology and Data in Real Estate |

| Abstract: | We show that personal experiences affect high-stakes economic decisions among inventors. Using matched patent and survey data from French and German inventors linked to natural disaster records, we exploit exogenous variation in disaster exposure. Inventors personally affected by natural disasters subsequently produce 8.2% more green patents, primarily driven by emission-reducing mitigation technologies, while non-green innovation remains unaffected. The absence of sizable spatial spillovers highlights the importance of personal experience. Disaster exposure shapes innovation choices by altering profitability expectations through shifting higher-order beliefs about consumer demand and anticipated regulation. Embedding this channel in a formal model, we disentangle the role of expectations and intrinsic motivation. The model predicts, and the data confirm, that effects are strongest in competitive markets, where profit incentives matter most. |

| Abstract: | Purpose - Integrating sustainability considerations into valuation practices is essential for promoting sustainable real estate investments. However, a comprehensive understanding of how sustainability factors impact the value of real estate assets is required. This study addresses the growing importance of renewable energy and the underutilized potential of rooftops by proposing an innovative framework for the valuation of roofs when used for renewable energy production.Design/methodology/approach - This study uses the concepts of residual value analysis and Highest and Best Use methodology, adapting them to create a new framework for rooftop valuation.Findings - The value of a roof can be determined based on their energy generation capability, where the conditions for enhanced energy harvesting potential distinct a higher value to the host asset. This removes the hurdle for investors to use rooftops for renewable energy investments.Originality - The novelty of this study lies in using the Highest and Best Use methodology in the valuation of roofs. To the best of our knowledge, no explicit valuation of roofs has been done in the context of renewable energy production.Practical implications- This study contributes to innovative valuation methodologies by incorporating sustainable measures. Social implications - Social implications include the evaluation of third-party investments in renewable energy on rooftops. This could lead to increased investments and higher renewable energy production, thereby lowering energy costs and enhancing the energy supply's reliability. |

| Abstract: | Environmental impact assessments of machinery and equipment (ME) are constrained by process-based life cycle assessment (LCA) with limited system coverage, and by aggregated top-down models with reduced representativeness. Lack of knowledge about consistency across these approaches hampers understanding of ME impacts and policy-making. This study quantifies greenhouse gas (GHG) emission multipliers (cradle-to-gate emissions per unit production) of ME using data from process LCA (ecoinvent), national environmentally extended input-output (EEIO) models and a multi-regional EEIO model (EXIOBASE) for the United States, China, Japan, and South Korea, assessing variations, reliability and compatibility. While EXIOBASE (7 ME sectors) and national EEIO data (32-102 sectors) broadly align, national EEIO models differ more in production technologies, with deviations from 100-fold lower to 3.7-fold higher than EXIOBASE results. Ecoinvent offers broad ME product-level coverage (~390 sectors), especially for general and electrical ME, but with uneven representation and limited geographic differentiation. Its multipliers vary widely and often exceed EXIOBASE values, challenging the assumption that process-based LCA underestimates impacts due to truncation. Overall, our results reveal cross-model variation, confirm the relative reliability of EEIO data, point to limitations in ecoinvent, and underscore the need to link technical detail with global trade representation in ME modeling. |

| Abstract: | With the transition to renewable energy, global production cost patterns for industrial materials and products are shifting, potentially creating what has been termed the renewables pull. This paper conducts a systematic review to identify and synthesise the growing body of scientific literature on this emerging topic. Out of 4, 813 studies screened, 81 peer-reviewed journal articles were found to be relevant. Most of these were published after 2020, with the number of publications increasing every year since then – indicating rapidly growing research interest in the field. Most studies originate from countries such as Germany or Australia, which are also identified as a potential major importer or exporter, respectively, within newly emerging renewable-based trade patterns. In contrast, while Japan and South Korea are frequently identified as potential importers, relatively few studies originate from these countries. Most of the identified literature conducts techno-economic analysis assessing the location-specific production costs of hydrogen-based derivatives and materials such as ammonia, methanol or steel produced using solar and wind electricity. Overall, the existing literature regards the renewables pull as potentially significant, although several studies emphasise that its realised impact depends on complementary locational factors, such as financing costs and policy context. Future research should expand the methodological approaches applied to this young and rapidly evolving field to assess the implications of the renewables pull for global production locations and value chain configurations, trade dynamics, and broader macro- and socioeconomic as well as geopolitical developments. |

| Abstract: | Primary copper production capacity is crucial given future demand and social, environmental, technical, economic, and political constraints, often overlooked in decarbonization pathway models. To address this, we propose a methodology to examine the consistency of the basic drivers of Shared Socioeconomic Pathways (SSPs) for primary copper requirements using the DyMEMDS stock-flow model. Our approach involves projecting primary copper production capacities to 2050 on a mine-by-mine basis, integrating mining industry dynamics based on commercial data. Results indicate significant concerns regarding the consistency of SSPs' basic drivers for copper requirements, revealing potential gaps exceeding 40 Mt in worst-case scenarios. Such discrepancies could impact technology deployments necessary for socioeconomic and decarbonisation assumptions. We recommend that the decarbonization modeling community align scenarios with mining industry constraints. Considering resource efficiency and circular economy strategies is essential for proposing more consistent scenarios to decision-makers, thereby mitigating risks of copper supply shortages hindering climate action |

| Abstract: | Kuwait faces critical environmental challenges driven by high per capita energy consumption, car-dominated urban development, and fossil fuel dependency. Despite national commitments to carbon neutrality by 2060, there remains a significant gap between policy intentions and real-world implementation. This research investigates the intersections of governance, user behaviour, and policy-practice mediation across the housing, energy, and transport sectors. By employing a mixed methods approach that integrates stakeholder engagement, comparative policy analysis, and the proposal of policy-practice mediation tools, the study aims to bridge policy and behavioural gaps. It highlights the role of data in accessing, informing, and monitoring policies and behaviours, and proposes stronger, dedicated institutions, a rethinking of energy subsidies, the adoption of bottom-up and participatory approaches, and the use of social media platforms for advocacy, communication, and the promotion of sustainable lifestyles. These interventions can contribute to advancing Kuwait’s sustainable transition through context-specific, evidence-based, inclusive, and scalable policy measures. |

| Abstract: | Systematic assessment of university contributions to the United Nations Sustainable Development Goals (SDGs) remains challenging due to the lack of standardized, scalable evaluation frameworks. This paper introduces a comprehensive four-pillar assessment framework combining advanced natural language processing and machine learning techniques with qualitative analysis to evaluate university engagement across Research, Education, Organizational Governance, and External Leadership dimensions. We demonstrate the framework's application through an empirical case study of Athens University of Economics and Business (AUEB), analyzing 870 working papers, educational curricula, organizational policies, and partnership activities. The automated content analysis reveals strong alignment with institutional and partnership-oriented goals (SDG 16: 99% coverage, SDG 17: 95.8%), economic development goals (SDG 8: 80.7%, SDG 9: 80.1%), and gender equality (SDG 5: 81.4%), while identifying significant gaps in environmental SDGs. The framework's multi-method approach, combining zero-shot classification, semantic similarity, named entity recognition, pattern matching, and topic modeling, provides reliable and transparent assessment suitable for replication across diverse institutional contexts. This replicable methodology enables universities worldwide to systematically evaluate their SDG contributions, identify strategic priorities, and enhance accountability to sustainable development commitments. |

| Abstract: | The extreme weather events of recent years have highlighted the vulnerability of real estate assets to climate risks and the urgent need to adapt the built environment to the unavoidable impacts of climate change. Institutional investors, as key stakeholders in commercial real estate, play a critical role in this effort. However, little is known about their decision-making behaviours and the processes that drive or hinder investments for climate adaptation measures in existing assets. This paper investigates the decision-making behaviours of institutional real estate investors through the lens of institutional theory, offering a framework to analyse both the rational and the cognitive tendencies that influence climate adaptation investment decisions. Using a qualitative research approach, the study draws on semi-structured interviews with senior managers across the different management levels of institutional real estate investors in the Netherlands. The findings aim to identify and classify the underlying tendencies shaping these decisions into normative, coercive, and mimetic pressures. By doing so, this study will provide valuable insights for industry practitioners to enhance their decision-making practices towards climate adaptation, offer guidance to policymakers on where regulations, policies, and incentives are needed, and contribute to the existing body of literature on real estate investor behaviour in the context of climate change. |

| Abstract: | Recent energy tensions caused by conflicts in Ukraine and the Middle East have added to the pressure that global warming exerts for an energy transition towards low-carbon energy sources. This study combines two time series approaches with the aim of delving deeper into the relationship between environmental degradation and economic growth and to test the environmental Kuznets curve (EKC) hypothesis, using information from 20 European countries between 2007 and 2021. Overall, the obtained results suggest the existence of a N-shaped nexus between emissions and income per capita. Additionally, we evaluated stability of this nexus and the potential existence of an asymmetric adjustment. In most countries we find asymmetries in the adjustment of emissions to positive and negative changes in income, but not so much in economic complexity. However, notable differences are observed between countries, which could be indicating their differentiated phase in the EKC curve |

| Abstract: | Global climate change is leading to rising temperatures and has numerous ecological consequences, such as heatwaves, droughts, and heavy rainfall. Urbanization further exacerbates the climate crisis as the density of buildings and the extensive sealing is leading to a substantial increase in temperature in urban areas. The paper aims to examine whether the phenomenon of the so-called Urban Heat Island (UHI) has an impact on property prices and whether temperature fluctuations affect price trends in one of the most densely populated cities in Europe, Berlin. For the evaluation, daily temperatures on a 30-metre by 30-metre grid are considered from 2014 to 2023. The corresponding UHIs are conducted on the basis of the relative temperature differences between the location of a property and the overall mean temperature of the sample. Within a semi-parametric model, non-linear relationships between variables are permitted, enabling an in-depth analysis of meteorological data and property information. The results reveal that temperature differences, particularly at night, have a significant impact on real estate prices in Berlin. This highlights that in the context of urbanisation, UHI has become a relevant issue in both economic and urban planning approaches. |

| Abstract: | Road freight transportation is a crucial enabler of the global economy due to its cost and flexibility advantages. However, road freight transportation also significantly impacts the environment, contributing to greenhouse gas emissions, traffic congestion, and pollution. To address this trade‐off, this study investigates the synergistic effects of tech‐enabled capabilities on the sustainability of road freight transportation. Grounded in the natural resource‐based view (NRBV) theory, it identifies tech‐enabled capabilities for sustainability, explores their interrelationship, and determines how these capabilities can contribute to a competitive advantage. A mixed‐methods approach was employed, comprising five phases: capability identification, expert validation using the Fuzzy Delphi method, development of a structural model via Interpretive Structural Modeling (ISM), analysis of interrelationships using Cross‐Impact Matrix Multiplication Applied to Classification (MICMAC), and creation of an Integrated Capabilities Framework for Sustainability in Road Freight Transportation (ICF‐SRT). Findings highlight three groups of capabilities—pioneer, integrator, and ancillary—each playing a distinct role in enhancing sustainability and competitive advantage in road freight transportation. The study advances NRBV theory by mapping the interdependencies of tech‐enabled capabilities and demonstrating their role in fostering sustainable practices. It provides road freight companies with a strategic framework for integrating and optimizing technologies to improve sustainability efforts, align with environmental and social governance (ESG) standards, and maintain a competitive edge in an eco‐conscious market. |

| Abstract: | Purpose This study investigates the impact of contract farming (CF) on chemical input usage (fertilisers, pesticides and herbicides) in wheat farming in Haryana, India, weighing on environmental risks from unsustainable chemical input usage under CF. Design/methodology/approach The research employs an endogenous switching regression (ESR) model using data from 754 farm households, enabling a comparative analysis between contract and non-contract farmers. Findings The results show that farmers who adopted CF would have reduced chemical input usage by 26.8% if they did not adopt it. Conversely, non-adopters would have increased chemical input usage by 54% if they adopted CF. While CF enhances farm productivity and income, it also increases chemical input usage, posing risks such as soil fertility loss and water contamination. Originality This study addresses the overlooked topic of chemical input usage in CF research. Leveraging household data and using an endogenous switching regression model provides unique comparative analysis and counterfactual scenarios. The findings contribute to understanding the environmental implications of CF and propose actionable recommendations for sustainable agricultural practices. Managerial or Policy implications The study recommends promoting organic farming and minimal chemical usage in CF agreements. Government intervention is needed to reduce the environmental impact of CF. Policies should promote environment-friendly fertilisers and provide guidelines on chemical usage based on crop variety, seed quality and soil fertility. Research limitations/implications The geographic focus on Haryana may limit generalisability. Reliance on cross-sectional data from a single season might not capture variability across different seasons. Future research could expand to other regions, use longitudinal data and investigate a broader range of crops. |

| Abstract: | The State of the Sovereign Transition 2025 report reviews the climate change performance of 85 high-, middle- and low-income countries assessed against the Assessing Sovereign Climate-related Opportunities and Risks (ASCOR) framework, up from 70 countries last year. The expanded country universe covers around 90% of global greenhouse gas emissions and GDP, as well as 100% of four major government bond indices. Given the political headwinds against sustained climate action in the public and private sectors, this year we dedicate the ‘focus’ section of the report to analysing areas of progress and retreat in assessed countries. The United States stands out among high-income peers, its performance declining in multiple areas. Meanwhile, improved climate policies and disclosures in low- and middle-income countries suggest they are catching up with high-income countries. |

| Abstract: | This report assesses the climate ambitions of 26 major international banks, ten US super-regional banks, and two custodian banks The TPI Centre began assessing the banking sector’s progress on the low-carbon transition with a pilot study in 2022. This 2024 assessment includes an evaluation of 26 major international banks, 10 US super-regional banks and two US custodian banks, on two elements: Net Zero Banking Assessment Framework (NZBAF) Carbon Performance The results of our 2024 assessment send a clear message: the overwhelming majority of banks are still in the early stages of their transition to a low-carbon economy. This is despite the fact that most banks we assess are now publicly disclosing some of their financed emissions and half are committing to reducing them to net zero by 2050. Yet, banks score poorly on both the NZBAF and Carbon Performance assessments. |

| Abstract: | The Democratic Republic of the Congo (DRC) faces a severe energy crisis, with over 90% of rural households relying on firewood and charcoal for cooking—fuels that drive deforestation, environmental degradation, and severe health risks. Despite these dangers, economic constraints and supply accessibility dictate household energy choices. This study investigates perceptions of firewood and charcoal quantity and quality among 287 rural households in Bita to assess the potential acceptance of cassava-based ethanol as a future alternative. Findings reveal that households prioritize fuel availability over quality and health considerations, highlighting a major challenge for transitioning to cleaner fuels. Younger households and those with respiratory illnesses are more critical of charcoal, yet economic barriers reinforce dependence on traditional fuels. Using the Multi-Level Perspective (MLP) and Diffusion of Innovation (DOI) theories, the study underscores that any alternative must be widely accessible, cost-competitive, and behaviorally acceptable. While ethanol presents a promising solution, its adoption depends on price competitiveness, awareness campaigns, and infrastructure development. This research provides critical insights for energy policies, emphasizing the need for targeted interventions to break the cycle of fuel poverty and accelerate a sustainable energy transition in rural DRC. |

| Abstract: | This paper proposes a renewed understanding of sustainability for services within the framework of Society 5.0. While sustainable services have long been defined by the Triple Bottom Line approach, i.e. simultaneously addressing economic, social, and environmental dimensions, this paradigm often neglects the transformative impact of digital technologies on service ecosystems. Building on an extensive literature review, we conceptualize sustainability as a dynamic, multi-dimensional construct shaped by emerging socio-technical systems. We integrate Service-Dominant Logic (SDL) and the IHIP characteristics of services to highlight how intangibility, co-creation, and relational dynamics uniquely position services to foster sustainable value. Our analysis distinguishes between weak sustainability, which relies on technological substitution to mitigate environmental degradation, and strong sustainability, which embeds ecological limits and human well-being at the core of service design. Within Society 5.0, advanced technologies such as AI, IoT, and cyber-physical systems offer opportunities to optimize resource use, enhance social inclusion, and regenerate ecosystems. However, true sustainability requires systemic changes in values and governance, challenging growth-oriented paradigms. We develop a conceptual framework that bridges ecological economics and service research, showing how services can evolve into human-centered, technologically enabled ecosystems that harmonize economic viability, social equity, and environmental resilience. This work contributes to advancing sustainable service theory by offering an integrative, future-oriented perspective that aligns digital transformation with strong sustainability principles. |
| Abstract: | Cet article propose une nouvelle conception de la durabilité des services dans le cadre de la Société 5.0. Si les services durables ont longtemps été définis par l'approche du triple résultat, c'est-à-dire la prise en compte simultanée des dimensions économiques, sociales et environnementales, ce paradigme néglige souvent l'impact transformateur des technologies numériques sur les écosystèmes de services. Sur la base d'une analyse approfondie de la littérature, nous conceptualisons la durabilité comme une construction dynamique et multidimensionnelle façonnée par les systèmes socio-techniques émergents. Nous intégrons la logique dominante des services (SDL) et les caractéristiques IHIP des services afin de mettre en évidence la manière dont l'intangibilité, la co-création et la dynamique relationnelle positionnent de manière unique les services pour favoriser la valeur durable. Notre analyse distingue la durabilité faible, qui repose sur la substitution technologique pour atténuer la dégradation de l'environnement, et la durabilité forte, qui intègre les limites écologiques et le bien-être humain au cœur de la conception des services. Dans le cadre de la société 5.0, les technologies avancées telles que l'IA, l'IoT et les systèmes cyber-physiques offrent des possibilités d'optimiser l'utilisation des ressources, d'améliorer l'inclusion sociale et de régénérer les écosystèmes. Cependant, une véritable durabilité nécessite des changements systémiques en matière de valeurs et de gouvernance, remettant en question les paradigmes axés sur la croissance. Nous développons un cadre conceptuel qui fait le pont entre l'économie écologique et la recherche sur les services, montrant comment les services peuvent évoluer vers des écosystèmes centrés sur l'humain et rendus possibles par la technologie, qui harmonisent la viabilité économique, l'équité sociale et la résilience environnementale. Ce travail contribue à faire progresser la théorie des services durables en offrant une perspective intégrative et tournée vers l'avenir qui aligne la transformation numérique sur les principes de la durabilité forte. |

| Abstract: | Historical data show a rising trend in extreme heat in the past four decades in the Groundnut Basin of Senegal. We evaluate the economic costs of extreme heat on groundnut production in the region. Using temperature data from the ERA5 global climate reanalysis, we define extreme heat degree days (EHDDs) as the cumulative number of degree days above 35 °C during the groundnut growing season and estimate its effect on quasi-profits and yields at the person, household, and field levels utilizing a two-year panel data of 1, 123 households. Our econometric estimations show that an additional EHDD reduces quasi-profits by 5, 460 FCFA per hectare and significantly lowers yield by 2.5%. Further, rainfall interactions with EHDD generate compounding losses under high heat and rainfall. The findings highlight important and often unseen effects of increasing temperatures on agricultural practices in climate-vulnerable areas such as the Groundnut Basin and underscore the need for adaptation and mitigation strategies to cope with the impacts of climate change. |

| Abstract: | Recently, several EU countries, including the Republic of Ireland, have struggled to meet legally binding commitments to reduce agricultural ammonia emissions. Some farmers readily embrace abatement measures, whereas others reject them. Research exploring technology rejection decisions is rare; however, understanding why some farmers reject recommended farming practices holds critical information for tailoring government support schemes and reducing pro-19 innovation biases. This study builds on Technology Acceptance Model, data collected from focus group discussions with dairy and beef cattle farmers across eight key farming regions and inductive thematic analysis. Three main themes, six subthemes and 26 codes were defined. Perceived costs of bovine farming methods include affordability, compatibility, usability, availability, and sufficient information which may lead farmers to reject adoption. Participants were frustrated with societal pressure for reducing emissions on farms and lack recognition for environmental services of grasslands, food production for humans and progress achieved towards environmental sustainability. Policy issues relating to slurry closing date and support schemes were identified. It is recommended to support small farms for adopting abatement technologies and to develop methods suitable to land and soil properties as well as local weather. |

| Abstract: | South Africa’s energy transition unfolds within a complex landscape of urgent decarbonization needs, persistent energy insecurity and global competition over renewable value chains. Thus, the central question we ask in this policy brief is: which localization measures could strengthen equity considerations in the energy transition? Based on interviews conducted with stakeholders in South Africa’s energy and industrial policy sectors, and augmented by current academic literature and policy documents, this policy brief finds that policy and incentive gaps undermine domestic manufacturing, job creation and community ownership in the renewable energy sector. Without a stronger localization strategy, the Just Energy Transition Partnership could fail to deliver on its equity promises. Key recommendations include reforming public procurement to reward local content and social impact, leveraging concessional finance to attract private investment in domestic renewable energy industries, establishing bilateral partnerships for technology transfer, facilitating industrial upgrading and promoting community and worker-owned renewable energy initiatives. |

| Abstract: | This scoping review and multi-tiered qualitative analysis examines data collected through the QuantiFarm project, literature, policies and EU projects to understand the roles of stakeholders in influencing European farmers to adopt Digital Agricultural Technology Solutions (DATSs). The paper adopts a holistic sustainability framework to address economic, social and environmental factors which influence farmers' decision-making about DATSs adoption. Key stakeholders, namely farmers, advisors, technology providers and policymakers, play unique and complementary roles in creating an innovation ecosystem. During the lifecycle of DATSs adoption, farmers face multiple drivers and barriers. Challenges such as cost, ease of use, data ownership, and interoperability continue to hinder uptake of technologies. Farmers often cite concerns about lack of transparency regarding costs, unclear benefits, and a lack of aftermarket (post-adoption) support. Advisors and technology providers must bridge these gaps by fostering trust, simplifying access to resources and co-developing solutions. Policymakers must ensure that incentives, education, and funding mechanisms are targeted and accessible to farmers of all scales. This study synthesises diverse perspectives and presents actionable recommendations to enhance stakeholders’ roles in the DATSs adoption process, shaping policy frameworks which support sustainable technology adoption. Transparent communication, varied education, reliable advice, tailored farmer-centric technology design and behaviourally driven policies are critical enablers of adoption. Themes resulted from study analysis and are presented as behavioural interventions for embedding in future policy structures. These insights aim to empower policy makers across Europe to support stakeholders in providing farmers with the tools, knowledge and confidence to adopt technologies which improve resilience and sustainability across economic, social and environmental dimensions. |

| Abstract: | The Eligibility as Environmental Construct (EEC) framework interprets IDEA eligibility through an ecological lens, deepening the law's focus on access and participation. EEC repositions educational impact as a relational phenomenon emerging from the interaction between learner and environment. The framework draws on Bronfenbrenner's ecological systems theory, Vygotsky's social constructivism, and neurodiversity-affirming ethics to align IDEA's guarantees of Free Appropriate Public Education (FAPE) and Least Restrictive Environment (LRE) with ecological reasoning. The accompanying heuristic—the context-dependent communicator/learner—shows how this perspective can inform eligibility documentation and goal writing without creating new diagnostic categories. Assessment centers on contextual access rather than categorical severity, asking whether specialized instruction is needed to enable participation in environments typical for age peers. By integrating ecological theory, jurisprudence, and inclusive ethics, EEC offers practitioners a coherent framework for interpreting eligibility as environmental access. |

| Abstract: | Over the last twenty years, European policies to reduce emissions in the building sector have encouraged the introduction of sustainable business models, including Energy Performance Contracting (EPC) and its Italian evolution, Servizio Energia Plus (Energy Plus Service). The latter differs from the traditional EPC model in the ESCo's ability not only to carry out efficiency measures but also to supply energy for a period of ten years after the measure, ensuring integrated management and reducing risk for the customer. This study focuses on the Energy Plus Service and analyzes its specific characteristics and economic benefits to highlight its role in promoting sustainability in the Italian building landscape. The research is based on the application of two business models - a traditional and the Energy Plus Service - to a renovation project of an Italian case study. This approach makes it possible to compare a traditional business model with Energy Plus Service, highlighting the differences in terms of energy efficiency, economic sustainability, and risk management. The expected results should show that the Energy Plus Service model offers more effective solutions to climate and energy efficiency challenges than the traditional model and is better adapted to the economic and social specificities of the Italian context. This comparison is intended to show the concrete benefits resulting from the introduction of sustainable business models in the construction sector |

| Abstract: | This study focuses on two critical technological domains: mRNA technology in biotechnology and green hydrogen in clean energy, aligning with Ursula von der Leyen’s political guidelines for the 2024–2029 (European Commission, 2024c). mRNA technology represents a breakthrough in precision medicine, through its rapid, scalable and adaptable solutions, enhancing health resilience and long-term societal well-being. Similarly, green hydrogen is central to achieving climate neutrality and strategic autonomy under the European Green Deal, as it provides a pathway for industrial decarbonisation and energy security. The study demonstrates that system dynamics modelling can contribute significantly to the ex-ante impact assessment and, potentially, to ex-post evaluations of research and innovation (R&I) policies and policy portfolios. This methodological approach captures the complex interdependencies and non-linearities inherent in innovation systems, providing policymakers with a better, evidence-based understanding of how R&I policy measures interact over time and what plausible medium- and long-term outcomes different policy interventions may yield on competitive sustainability. Enriching a pipeline view of the innovation process by considering delays and feedback mechanisms brings these analytical possibilities but also emphasises on a deterministic view of the innovation process that is more consistent with the reality of research organisations and corporations than startups and other types of innovative organisations. |

| Abstract: | Groundwater management, especially in Mediterranean regions such as Tunisia, is challenging due to diverse stakeholder interests and the arid climate, which makes the sustainability of water resources extremely difficult. This paper proposes an innovative approach to the design of decision and policy alternatives by combining Problem Structuring Methods (PSMs) and the participatory tool based on the Concept-Knowledge (C-K) theory, named Policy-Knowledge, Concepts, Proposals (P-KCP). In a multi-methodological perspective, using Cognitive Maps and Value Trees in combination with P-KCP, the study aims to innovatively generate alternatives to address the sustainability issue of the case study, namely collective groundwater management. The paper provides a practical and adaptable guide to fostering innovation for policy design and generation of alternatives. By bridging decision theory and design theory, the study addresses the methodological gap in alternatives generation and highlights the role of C-K theory for supporting innovative design processes. Integrating PSMs and C-K theory, the multi-methodology advocates participatory approaches to address complex sustainability challenges, provides an adaptable, replicable tool, and encourages the creation of unconventional solutions. Ultimately, this paper offers new collective practices for groundwater management, expanding the set of alternatives through the integration of PSMs and C-K theory and reflecting on the applied multi-methodology. |

| Abstract: | Background and aim: The article investigates the systemic deficiencies and risks in Romania’s municipal waste management system during the post-pandemic period, focusing on the role of external public audit missions conducted by the Romanian Court of Accounts. The main objective is to assess the risk of infringement procedures against Romania due to persistent non-compliance with EU environmental directives. Scope and limitations: The research concentrates on the period 2015–2021, with particular emphasis on the case of Constanța County, and is limited to the analysis of official audit reports and regulatory frameworks. Methods: The study employs a qualitative methodology based on document analysis, comparative evaluation of legal frameworks, and synthesis of audit findings, with emphasis on compliance, infrastructure, and institutional performance. Results: Findings highlight significant shortcomings: delayed closure of non-compliant landfills, insufficient implementation of selective collection and recycling, lack of a functional electronic traceability system, and weak monitoring by central and local authorities. Constanța County illustrates critical infrastructural and contractual deficiencies that compromise EU compliance targets. Conclusions: Romania remains at high risk of EU sanctions due to poor waste management performance, limited strategic coordination, and underuse of European funding. Originality: The article provides an integrated perspective by linking external audit findings to broader systemic vulnerabilities in the post-pandemic context. Practical implications: The study offers actionable recommendations for improving compliance, strengthening administrative capacity, and ensuring alignment with EU circular economy goals, thus supporting policymakers and practitioners in sustainable waste governance. |

| Abstract: | The paper reports findings from a real estate study examining asset management decision-making outcomes for urban population health and wellbeing in a five-year programme funded by the United Kingdom Prevention Research Partnership (UKPRP). We find that despite an industry appetite for demonstrating how portfolio strategies promote sustainable urban environments that produce resilient risk-adjusted returns on investment, there is a paucity of health and wellbeing data to inform portfolio management models. Evidence of responsible Environmental, Social, Governance (ESG) performance has become seen as a commercial priority but environmental sustainability has taken precedence in investor reporting due to the superior availability of carbon data. Focusing on two large investment management funds with extensive UK urban asset portfolios, we take on the challenge of testing how monetised health and wellbeing value generated by urban redevelopment can inform asset management healthy urban placemaking aligned with investor financial returns aspirations. We conclude that In the context of the contemporary financialization of property and assetization of urban space, urban land and property repurposing and upgrading presents an opportunity to create social value in operational models for wealth creation. |

| Abstract: | The green transition is expected to be one of the most significant forces shaping labor markets in the incoming years. As economies shift toward cleaner technologies, green jobs will expand, while employment in high-emission sectors will either decline or move into other sectors, depending on skill transferability and policy design. In this context, the ability of workers to transition between green and non-green jobs will be crucial to ensure a just labor market adjustment. Labor transitions into and out of green jobs remain understudied, particularly in developing economies where data constraints limit empirical analysis. This paper addresses this gap, using household survey data and a synthetic panel approach to estimate the probability of labor transitions employs a skills-based green index. The results reveal a high degree of labor market persistence, explained by the role of skills in shaping mobility, and show a wage premium of 10.6% for green occupations compared to their non-green counterparts. These findings have important policy implications for ensuring a just energy transition. Given the observed rigidities in green labor mobility, targeted upskilling and reskilling programs are important to enabling non-green workers to acquire the necessary skills for green jobs. |

| Abstract: | In 2013, the European Union Common Agricultural Policy introduced a set of compulsory greening measures in its subsidies scheme in order to achieve environmental goals. We analyse the impact of this reform, and particularly the definition of Ecological Focus Areas (EFA), on bird diversity in France. We match bird observations from the French Breeding Bird Survey (BBS) to parcel level information on agricultural land use and type of crops. We exploit the heterogeneous exposure of bird observation sites to the reform depending on their ex-ante extent of arable area in a continuous difference-in-differences approach. We find evidence of an increase in overall bird abundance after 2015 in sites with a higher ex-ante proportion of arable land, driven by a small number of generalist species, and no impact on species richness and phylogenetic diversity. A decomposition by diet type suggests that vertebrate eaters were positively impacted by the reform. By contrast, cropland species experienced the most dramatic decline after 2015 in sites with a higher share of arable area. Estimations of the dynamic effects of the reform suggest that the observed positive effects on bird abundance were limited to the first two years after its implementation. Based on observational data, our findings confirm previous concerns regarding the effectiveness of the 2013 reform in preserving biodiversity. |

| Abstract: | This paper develops a nonparametric framework for identifying and estimating spatial boundaries of treatment effects in settings with geographic spillovers. While atmospheric dispersion theory predicts exponential decay of pollution under idealized assumptions, these assumptions—steady winds, homogeneous atmospheres, flat terrain—are systematically violated in practice. I establish nonparametric identification of spatial boundaries under weak smoothness and monotonicity conditions, propose a kernel-based estimator with data-driven bandwidth selection, and derive asymptotic theory for inference. Using 42 million satellite observations of NO$_2$ concentrations near coal plants (2019-2021), I find that nonparametric kernel regression reduces prediction errors by 1.0 percentage point on average compared to parametric exponential decay assumptions, with largest improvements at policy-relevant distances: 2.8 percentage points at 10 km (near-source impacts) and 3.7 percentage points at 100 km (long-range transport). Parametric methods systematically underestimate near-source concentrations while overestimating long-range decay. The COVID-19 pandemic provides a natural experiment validating the framework's temporal sensitivity: NO$_2$ concentrations dropped 4.6\% in 2020, then recovered 5.7\% in 2021. These results demonstrate that flexible, data-driven spatial methods substantially outperform restrictive parametric assumptions in environmental policy applications. |

| Abstract: | Reducing agricultural inputs is necessary for sustainable farming, but raises concerns over yields and farmers' income. Here, we used large-scale experimental trials on cereal fields in western France for the period 2022-2023 to assess the effects of input reductions on yields and gross margins under real farming conditions. The trials, co-designed with farmers, involved substantial nitrogen and pesticide reductions in conventional fields, and reductions in soil work or mechanical weeding in organic fields. The results showed that input reductions led to average yield gaps of about 5% in both conventional and organic systems. Cost savings compensated for economic losses and even surpassed these in many conventional field experiments. Simulated price scenarios confirmed the economic viability of input reductions, with heightened advantages during price crises driven by energy or inflation shocks. These findings demonstrate that input-reduction strategies can align environmental and economic goals in real farming conditions, challenging concerns about profitability while supporting the ambitious sustainability targets of policies. |

| Abstract: | This study examines recent agriculture sector development trends in Khatlon region of Tajikistan and its contribution to development of the sector between 2010 and 2021. The findings of the study show that the development of the crops sector in the region was strongly intensive, except sluggish intensive growth for cotton and extensive growth for potato. Further deep dive is needed to figure out the source of growth, however, lack of disaggregated data prevents us from doing so in this analysis. To understand the drivers of recent growth the farmers survey needs to be conducted. Unlike the crop sector, the livestock sector in Khatlon region has experienced mainly extensive growth, with surge up in cattle and small ruminants’ population rather than productivity increase. The livestock sector faces several challenges such as severe degradation of pastures due to poor pasture management system, and increased pressure on pasture due to rapidly growing livestock numbers. In addition, the sector is affected by climate change and at the same time accelerates the ongoing process of climate change due to greenhouse gases, especially methane emissions. In sum, the region now plays a vital role in meeting Tajikistan's food security needs and income generation for rural households, however, further sustainable growth of the sector requires addressing challenges, increasing investments into the sector and promoting CSA practices (Table 1A in Appendix). |

| Abstract: | Environmental pollution is often observed to cause disproportionate distribution of environmental harm to ethnic and racial minorities, low-income and other disadvantaged social groups. Previous economic studies discovered a relationship between ethnic origin and exposure to harmful environmental toxins that impair human health. However, no such research was conducted comparing US states with large and diverse US Hispanic communities (California, Texas, Florida, Arizona, and New Mexico) and Puerto Rico. Thus, a highly granular set of demographic and economic data was analyzed from the US Census, combined with the latest available healthcare data from the US Center for Disease Control (CDC) and environmental pollution data from the US Environmental Protection Agency (EPA). Independent variables were selected from a variety of environmental pollution factors. The dependent variables were designated as Health Equity outcomes measured by the prevalence of three main illnesses: asthma, diabetes, and coronary heart disease. Pair correlations were then explored to determine the most important determinants of health outcomes and evaluated three study hypotheses. Multivariable linear regression analysis was used to evaluate health equity for several US states with a large Hispanic population. The analysis shows that the Puerto Rico population has been more negatively impacted by environmental and social factors than the majority Hispanic US mainland districts. Across the compared states, California had the worst environmental pressure, Arizona and Puerto Rico the most negative economic status and worst health outcomes. Overall, Florida had the best mix of outcomes for the Hispanic community. |

| Abstract: | This study investigates the resilience of green premiums and brown discounts on German residential property markets during the ongoing economic crisis. While previous research extensively examines green premiums and brown discounts in growing markets, little is known about their persistence during economic downturns. We address this gap by exploring how green building characteristics, especially energy efficiency, influence property values in challenging market conditions. The setting of the study is the ongoing German real estate market crisis, marked by soaring energy prices, inflation, rising construction costs and rapid interest hikes. It severly reduced residential property values in Germany, providing a suitable market phase to investigate whether investing in sustainable properties can offer a hedge against negative market developments. The study analyses an extensive dataset, covering detailed hedonic characteristics for German residential property markets spanning from 2017 to 2024. Given the immediate onset of the crisis in February 2022, a Difference-in-Differences analysis is used to examine a potential impact of the economic downturn on green premiums and brown discounts. The research provides policymakers and investors with valuable insights into green premiums and brown discounts by analysing if energy-efficient properties benefit from enhanced economic resilience. The findings indicate whether sustainable investments should be prioritised in residential property markets to support long-term stability and mitigate the impacts of volatility. To the best of the authors’ knowledge, this study is the first to provide empirical insights into the resilience of green premiums and brown discounts to challenging market periods. |

| Abstract: | The year 2024 marked a critical milestone in global warming, with global mean temperatures exceeding pre-industrial levels by 1.55 °C. Polar ice loss, largely driven by anthropogenic CO₂ emissions, exhibits highly nonlinear dynamics that challenge conventional linear modeling approaches. This paper investigates the nonlinear effects of CO₂ on Arctic and Antarctic sea-ice volumes using regime-switching econometric models defined for both accumulated concentration levels and annual changes in CO₂. Specifically, we estimate reduced-form Smooth Transition Autoregressive (STAR) and Threshold Autoregressive (TAR) specifications using data generated from General Circulation Models (GCMs). We consider the identification of CO₂ thresholds and the evaluation of sea-ice dynamics under alternative CO₂ emissions trajectories, such as the IPCC’s Shared Socioeconomic Pathways (SSPs). Our results reveal important threshold effects across hemispheres. For the Arctic, a single CO₂ threshold is identified at approximately 330 ppm (or 𝛥𝐶𝑂2 = 1.16 ppm), while for the Antarctic, two thresholds emerge at 285 ppm (or 𝛥𝐶𝑂2 = 0.13 ppm) and 321 ppm (or 𝛥𝐶𝑂2 = 0.56). Beyond these points, the decline in sea-ice volume accelerates sharply. Forecasts under business-asusual (BAU) scenarios suggest that the Arctic could become ice-free around 2060 [2045, 2078], while Antarctic sea-ice loss may extend well beyond 2100. Under an intermediate emissions path, such as SSP2-4.5, recovery of sea-ice volume remains feasible if global CO₂ growth begins to decline after 2035 by an average of 3.2 ppm every year, with projected reversion to historical levels around 2075 for both hemispheres. |

| Abstract: | Peatland provides significant value to English food production and economy, with their drainage and use leading to extensive degradation and GHG emissions. Although some agri-environmental policies support paludiculture, there remains significant uncertainty as to the private and public benefit of adopting paludiculture by landholders, especially in landscapes where lowland peats are patchy. Using a case study approach, we define the private and social benefits of six landholders in the West Midlands of England adopting paludiculture or peatland restoration for biodiversity markets to minimise or reverse further lowland peat degradation. A stochastic bioeconomic modelling approach is applied which integrates land use alternatives, payments from agri-environmental policies, and monetisation of biodiversity net gains when lowland peats are restored for habitat gain. In addition to the substantial capital costs of rewetting a catchment, land use opportunity costs, and regulatory and compliance costs affects the minimum feasible scale of rewetting lowland peat. These present significant barriers to the adoption of paludiculture, and current agri-environmental policies and payments are unlikely to be conducive to the adoption of paludiculture in small scale non-contiguous lowland peat. This puts at risk extensive areas of fragmented lowland peat and may result in continued lowland peat degradation, agriculture’s contribution to GHG emissions and catchments not benefiting from the flood mitigation and biodiversity gain opportunities rewetting lowland peat provides. Monetisation of biodiversity net gains when restoring lowland peat habitats potentially offers the most economically beneficial pathway to protecting England’s patchy lowland peats. |

| Abstract: | Description of the subject. Agriculture-livestock integration is one of the strategies adopted by agropastoralists in the North Cameroon region to reduce the risks associated with demographic pressure and climate change, in order to improve their productivity. Objectives. The aim of the study was to characterize the systems and practices for managing and recycling animal and plant co-products on agropastoral farms in northern Cameroon, as this is one of the keys to agroecology in agropastoral systems. Method. An in-depth survey was conducted on 108 selected farms. The data were analyzed using multivariate analysis (PCA) followed by classification (CAH). Results. Characterization according to farm structure, co-product management practices and technical performance enabled us to identify four classes of farm, namely small farms mainly focused on crop production (class 1), farms specializing in livestock farming (class 2), medium-sized farms combining crop production and livestock farming (class 3) and very large agro-pastoral farms (class 4). On average, farms used 28% of plant by-products to cover 25% of their fodder requirements (straw, tops), and 23% of animal by-products to cover 35% of their organic manure requirements (animal waste). Conclusions. This study showed that the recycling of co-products in agro-pastoral farms is low but increasing. |

L'intégration agriculture-élevage est l'une des stratégies adoptées par les agropasteurs de la région du Nord-Cameroun pour réduire les risques liés à la pression démographique et aux changements climatiques afin d'améliorer leur productivité. Objectifs. L'objectif de l'étude est de caractériser les systèmes et pratiques de gestion et de recyclage des coproduits animaux et végétaux dans les exploitations agropastorales du Nord-Cameroun car cela constitue une des clés de l'agro-écologie dans les systèmes agropastoraux. Méthode. Une enquête approfondie a été réalisée dans 108 exploitations choisies de façon raisonnée. Les données ont été analysées par une analyse multivariée (ACP) suivie d'une classification (CAH). Résultats. La caractérisation selon la structure des exploitations, les pratiques de gestion des coproduits mises en oeuvre et les performances techniques a permis de dégager quatre classes d'exploitations, à savoir la classe des petites exploitations orientées principalement sur les productions végétales (classe 1), la classe des exploitations spécialisées dans l'élevage (classe 2), celle des exploitations de taille moyenne combinant cultures et élevage (classe 3) et enfin celle des grandes exploitations agropastorales (classe 4). En moyenne, les exploitations enregistrent un taux de valorisation des coproduits végétaux de 28 % pour couvrir 25 % de leurs besoins en fourrage (pailles, fanes) et un taux de valorisation des coproduits animaux de 23 % pour couvrir 35 % de leurs besoins en fumure organique (déjections animales). Conclusions. Cette étude a montré que le recyclage des coproduits dans les exploitations agropastorales est faible mais en voie de progression. |

| Abstract: | Xylella fastidiosa (Xf) is a xylem-limited bacterium that has been recorded in several European countries since its detection in 2013 in Apulia (Italy). Given the prominence of the wine industry in many southern European countries, a big threat is the development of Pierce's disease in grapevines. Yet, the insect-habitat and insect-plant interaction networks in which xylem feeders, possible vectors of Xf, are involved around European vineyards are largely unknown. Here we describe these networks in three key wine-growing regions of southern France (Provence-Alpes-Côte d'Azur, Occitanie, Nouvelle-Aquitaine) to identify primary xylem feeder habitats, and assess their specialization degree at the habitat, plant family, and plant species levels. A total of 92 landscapes (and 700 sites) were studied over three sampling sessions in the fall 2020, spring 2021, and fall 2021. Among the habitats sampled, meadows hosted the largest xylem feeder communities, followed by alfalfa fields. Vineyard headlands and inter-rows hosted slightly smaller xylem feeder communities, indicating that potential Xf vectors thrive near crops. Grapevines hosted few xylem feeders, suggesting rare but possible transfer to vulnerable crops. Philaenus spumarius, Aphrophora alni, Lepyronia coleoptrata, and Cicadella viridis were all similarly generalists at the habitat, plant family or plant species level. The only specialist was Aphrophora grp. salicina, which was restricted to riparian forests and to Salicaceae. Neophilaenus spp. were extremely specialist at the plant family level (Poaceae), but rather generalist at the habitat and plant species levels. All 1017 insects screened for the presence of Xf tested negative, showing that Xf is not widespread in the studied regions. Our study provides new basic ecological information on potential vectors of Xf, especially on their specialization and feeding preferences, as well as practical information that may be relevant for the design of epidemiological surveillance plans.which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. |

| Abstract: | Vertical farming (VF) offers a potential solution to enhance food security, support rural econ-omies, and advance sustainable agriculture by minimising water usage, reducing the need for land, and increasing crop yields. However, its adoption potential depends on consumer ac-ceptance and demand. This study explores consumer preferences and willingness to pay (WTP) for vertical farming produce through a choice experiment focused on bowls of ready-to-eat salad leaves. We focus on the case study of Scotland, a country whose pedoclimatic conditions limit on-field production of fresh vegetables. An online survey was conducted with a sample of 800 Scottish consumers stratified by age and gender. Participants were assigned to one of four treatment groups. Each group received different information about VF, emphasising re-spectively environmental benefits, localness and local development, or energy concerns, in ad-dition to a baseline with no additional information. We find very limited prior knowledge of VF, increasing the salience of our treatments. We detect no significant difference in preferences between VF and on-field production per se, neither in the baseline, nor under the different treatments, but relative preference for products providing this information. Taste consistency, freshness (residual shelf life), and local origin, all enhanced by VF production, were important drivers of consumers’ choices. In the absence of vegetables grown on-field in the UK, national VF products were still preferred to imported ones. These findings can inform policymakers, producers, and retailers about strategies to enhance consumer acceptance and market potential for VF production. |

| Abstract: | This study investigates the impact of flood risks on household financial decisions, with a focus on the default and repayment behavior and analyzes how their unrealistic optimism regarding Loan Prime Rate (LPR) transfer decisions affect credit loss during flood hazards. Through empirical analysis of loan data in China, we find that rural households who choose to switch to LPR are more likely to default after a flood, suggesting that these households are overly optimistic about their financial situations and underestimate the financial risks posed by floods. Additionally, the study finds that defaulted households adjust their financial expectations and exhibit more proactive repayment behaviors after the flood, highlighting that financial behavior is not static but adjusts based on real experiences such as the challenges posed by floods. Female and younger clients are more prone to defaults due to proactive risk-taking influenced by optimism, yet demonstrate improved repayment behaviors post-default, reflecting recalibrated financial strategies. The findings underscore the critical role of financial literacy and behavioral biases in mediating climate-related financial vulnerabilities. This study contributes to behavioral economics by linking environmental shocks to household financial resilience, emphasizing the need for targeted interventions to mitigate optimism-driven risks in vulnerable populations. |

| Abstract: | Tourism presents a significant, yet largely untapped, opportunity for Africa to accelerate economic development, create jobs, and foster inclusive growth. This case study for sports tourism in Kenya estimates that for every $1, 000 spent by a sports tourist, a total of $3, 600 is generated within the Kenyan economy, highlighting the sector's substantial linkages with other sectors, particularly the food system. By 2035, sports tourism could contribute an estimated $1.21 billion to $2.14 billion to Kenya's economy annually and support the creation of up to 237, 000 new jobs. About half of these jobs are expected to benefit lower and middle-income households, supporting their livelihoods and poverty reduction. To fully realize these economic and social benefits, strategic policy interventions are crucial, including targeted investment in tourism infrastructure, marketing, and skill development; a concerted effort to improve the overall business climate to incentivize private sector engagement; and enhanced inter-ministerial coordination between tourism, planning, agriculture and other key stakeholders. While this study focuses on economic impacts, realizing these benefits requires careful planning and sustainable practices to mitigate potential environmental and social challenges. |

| Abstract: | Although agriculture contributes to four main drivers of biodiversity loss, impact assessment of food products remains limited either to in situ measurements that prevent generalization, or to systematic models that are not validated by in situ data. Here we describe the BVIAS (Biodiversity Value Increment from Agricultural Statistics) model, which allows estimating the biodiversity impact of all major food products based on accountancy data and public statistics. BVIAS is calibrated based on the most relevant large-scale studies and meta-analysis. It is then used to find out whether major Food Quality Schemes (FQSs) have different practices and biodiversity impact than their conventional counterparts. We show that only mandated FQS specifications lead to significant practice differences. Consistent with in situ data, organic farms, as well as those producing Comté (Protected Designation of Origin), have less biodiversity impact on a per hectare basis. This local benefit is offset by lower yields, resulting in a higher impact per ton. However, biodiversity impact gap between animal and plant products (e.g., milk vs. wheat) is far greater than the difference between FQS and conventional versions of the same product. Taking into account the main drivers of biodiversity losses related to agriculture, relying on quantitative data for a large sample of farms and calibrating our model based on relevant large-scale studies and meta-analysis, we therefore propose here an objective, robust and operational method to estimate the impact of food products on biodiversity for use in environmental labeling schemes or other purposes. |

| Abstract: | Migration is an adaptation strategy to climate change and the associated extreme climatic events that increase in intensity and frequency. However, frictions and barriers to move induce an intention gap, i.e., a difference between intended and actual residential migrations. One of the original features of our paper is to exploit innovative data, that is, user activity on the real-estate platform SeLoger (mobility intentions) and La Poste mail forwarding contracts (effective moves), to get day-to-day information on reactions induced by a specific extreme event, and to compute a migration intention gap. We evaluate the impact on these three outcomes of a geographically and temporally well-defined extreme event, the unusually destructive forest fires in the Landes (France) in the summer of 2022. We build a control group similar to municipalities affected by these forest fires with a matching method and estimate difference-in-differences models. Our results show that this event both affected positively intentions and negatively real moves. Particularly, the intention gap increases: if households intend to move, they do not necessarily take action. |

| Abstract: | Biodiversity provides essential ecological, economic, and cultural value, yet it continues to decline under anthropogenic pressures driven largely by economic development. Although many corporations are developing biodiversity-related measures and reporting frameworks, their actual environmental awareness and responsibility remain critical. On 19 September 2025, the outdoor sports brand Arc’teryx held a large-scale fireworks event, Ascending Dragon in the Himalayas, in Shigatse, China, which drew widespread criticism for its potential negative environmental impacts. To evaluate the societal and financial consequences of this incident, we analyzed Chinese public responses based on Weibo discourse (public reaction), Baidu Search Index (public attention), and the stock performance of Anta, Arc’teryx’s parent company. Both reaction and attention peaked two days after the event, and we found a negative correlation between online trends and stock performance. Causal analysis further demonstrated a significant causal influence of Baidu search activity related to Anta on its stock price. Textual analysis revealed that public concern centered primarily on environmental impacts, followed by expectations of corporate responsibility. To our knowledge, this is the first study to demonstrate that a negative environmental event, together with the resulting public reaction and attention, can directly and immediately influence a company’s financial performance. These findings underscore the importance of genuine biodiversity awareness and responsible decision-making in corporate practice. |

| Abstract: | The pressing need to address the Sustainable Development Goals (SDGs) in business education demands a shift from traditional teaching methods toward design-inspired pedagogical models. This paper introduces a specific pedagogical innovation, that is, a Design for Iteration (DFI) strategy embedded within a studio-based learning environment, developed through a cross-institutional partnership to educate future business leaders. The studio model emphasizes experiential, visual, and iterative learning processes such as the ‘crit', prototyping, and peer-led feedback. Anchored in a heutagogical (self-determined) approach, this innovation moves beyond isolated creative exercises toward sustained engagement with complex, real-world sustainability challenges. Drawing on qualitative data from the implementation of the EULab Nantes studio, the paper explores how iterative, practice-based learning develops critical skills in adaptive thinking, problem-framing, collaboration, and system-level inquiry. The findings underscore the role of socio-materiality and peer-led sense-making in shaping meaningful learning and identifies the studio as a space for cultivating the mindsets and capabilities central to responsible management and sustainability education. By foregrounding the studio as a site for prototyping sustainable market futures, the paper contributes to reimagining business schools as platforms for transformative sustainability learning. |

| Abstract: | Due to its structural features, the Rwanda’s agri-food system is extremely vulnerable to the risks of climate variability. To accelerate and sustain growth in the food system, increase its resilience to shocks, and improve food security, the Rwandan government incorporated a list of climate-smart agricultural interventions into its updated Fifth Strategic Plan for Agricultural Transformation (PSTA-5) program, with ambitious, explicit targets. This paper assesses the impacts of these CSA interventions on Rwanda’s agri-food system, both with and without climate change, using historical declines in yield within agriculture as a proxy. Results show that modeled CSA practices during the PSTA-5 period (2024/25-2028/29) increase agricultural and overall GDP growth by 4.2 and 1.3 percentage points by the end of the plan period, respectively, with a long-term growth impact that stretches well beyond the plan period mainly owing to the persistent effects of irrigation and terracing. Cumulative agricultural GDP (2024/25-2028/29) would be 2.7 percent higher than the baseline outcome of no such CSA investments. We also find stronger household level effects, mainly in rural areas. Furthermore, a recurrent 1-in-5-year magnitude of climatic shock in Rwanda can cause substantial reductions in agricultural (-7.6 percent) and overall (-2.7 percent) GDP during the PSTA-5 period. The CSA interventions are impactful in minimizing the effects of climate change on the Rwandan economy. |

| Abstract: | This paper explores the economic role of tourism in Iceland, focusing on its contributions to GDP, job creation, and foreign exchange earnings. Using descriptive and comparative analysis of secondary data?relying on official statistics and a comprehensive body of literature?the study assesses the industry?s growth, resilience, and sustainability in both national and global contexts. The findings show that tourism has become a key part of Iceland?s economy, surpassing traditional export sectors in value and providing significant employment. However, the COVID-19 pandemic revealed the industry?s volatility and strong dependence on international markets, exposing structural weaknesses that threaten its long-term sustainability. Alongside economic aspects, the research also addresses critical issues such as over-tourism, seasonality, and environmental pressures, especially in fragile ecosystems. Recent academic research and shifting policy frameworks highlight the importance of sustainability measures, fair taxation, and participatory governance as guiding principles for the sector?s future. Overall, the study emphasizes that balancing economic growth with environmental limits and community well-being is essential to developing a more resilient and forward-looking tourism model. These insights serve as valuable guidance for policymakers, practitioners, and scholars working towards sustainable and diverse tourism |

| Abstract: | This paper develops a unified framework for identifying spatial and temporal boundaries of treatment effects in difference-in-differences designs. Starting from fundamental fluid dynamics equations (Navier-Stokes), we derive conditions under which treatment effects decay exponentially in space and time, enabling researchers to calculate explicit boundaries beyond which effects become undetectable. The framework encompasses both linear (pure diffusion) and nonlinear (advection-diffusion with chemical reactions) regimes, with testable scope conditions based on dimensionless numbers from physics (P\'eclet and Reynolds numbers). We demonstrate the framework's diagnostic capability using air pollution from coal-fired power plants. Analyzing 791 ground-based PM$_{2.5}$ monitors and 189, 564 satellite-based NO$_2$ grid cells in the Western United States over 2019-2021, we find striking regional heterogeneity: within 100 km of coal plants, both pollutants show positive spatial decay (PM$_{2.5}$: $\kappa_s = 0.00200$, $d^* = 1, 153$ km; NO$_2$: $\kappa_s = 0.00112$, $d^* = 2, 062$ km), validating the framework. Beyond 100 km, negative decay parameters correctly signal that urban sources dominate and diffusion assumptions fail. Ground-level PM$_{2.5}$ decays approximately twice as fast as satellite column NO$_2$, consistent with atmospheric transport physics. The framework successfully diagnoses its own validity in four of eight analyzed regions, providing researchers with physics-based tools to assess whether their spatial difference-in-differences setting satisfies diffusion assumptions before applying the estimator. Our results demonstrate that rigorous boundary detection requires both theoretical derivation from first principles and empirical validation of underlying physical assumptions. |

| Abstract: | This paper extends the existing individual decision-making framework of adapting to climate change by considering the effects of prior personal experience in shaping risk preferences. Conducting Prospect Theory-based “lab-in-field” risk experiments in rural areas of Xinjiang Province, we elicit Chinese farmers' risk curvature and probability bias by adopting more flexible Prelec's two-parameter probability functions. Using Bayesian approaches to estimation, we find that farmers' prior experiences not only provide information that influences the subjective distributions of future outcomes but also, by shaping farmers' personal risk preferences, affects how farmers absorb and update this information. As such, our research suggests that individual risk preferences can evolve, and the effects of personal experience on preferences exhibit distinct patterns depending on whether farmers face benefits or losses. Experiencing production damages tends to make farmers more averse to losses and increases their optimistic bias concerning personal loss risks. A policy implication of these findings is that it is crucial to reduce farmers' cognitive biases regarding their own climate-related losses and their over-reliance on personal experiences in order to make accurate risk management decisions. |

| Abstract: | Wildfires driven by extreme winds, such as the Camp Fire in 2018 and the Eaton and Palisades fires in 2025, account for a large share of structure losses due to wildfires in California. Because these types of events are relatively rare, their risks are difficult to estimate using conventional simulation techniques. This study explores the use of the Random Forest machine learning algorithm as an alternative method for estimating wildfire risk to structures. Environmental variables are estimated for 57, 000 structures destroyed in wildfires in California and for 6.2 million unburned structures with the potential for wildfire exposure. A Random Forest model, trained on both the burned and unburned structures, identifies which variables are most effective in distinguishing between the two and which unburned structures belong in the High-Risk category. The six environmental variables found to be the most important in identifying High-Risk structures are: · the annual Red Flag Warning hours (RFW) · the average Energy Release Component (ERC) · the Wildland Urban Interface Zone (WUI) · the Normalized Difference Vegetation Index (NDVI) · the annual number of downslope wind events (DW) · the proportion of sustained winds of 20 mph or greater on high fire danger days (SW20) By adjusting the maximum tree-depth parameter, the Random Forest model is calibrated to produce a state-wide percentage of High-Risk structures of 12% in order to match estimates by the California Department of Insurance (CDI). The CDI estimates are based on a weighted average of insurance industry risk models. Although the Random Forest model matches the CDI estimates for the percentage of High-Risk structures at the state level, the percentage by county differs significantly from the CDI numbers. The largest reductions in the percentage of High-Risk structures occur in the Central Sierra counties of Tuolumne and Mariposa ( -48% and -34% respectively). The largest increases occur in Mono County in the Eastern Sierras (+53%) and Ventura County in Southern California (+42%). Wind characteristics appear to be the primary reason for the differences in county risk ratings. Counties with fewer Red Flag Warning hours, fewer downslope wind days, and a smaller proportion of winds above 20 mph tend to have a smaller percentage of High-Risk structures than estimated by the CDI. |

| Abstract: | Many jurisdictions encourage households to adopt technologies that reduce greenhouse gas emissions and energy consumption, but there is little evidence on how these technologies affect the welfare of nonadopting households. We show that, in theory, adopting climate-friendly technologies that affect aggregate electricity demand, such as rooftop solar photovoltaics or electric vehicles, can increase or decrease average retail electricity prices in the short run; if the variable cost curve for electricity generation is sufficiently flat, higher demand reduces prices (and vice versa). Analysis of US residential electricity price and consumption data, as well as simulations of a computational electricity generation model, suggests that this variable cost condition holds. Adopting technologies that reduce consumption raises average retail prices, harming nonadopters; adopting technologies that increase electricity demand reduces average electricity prices, benefiting nonadopters. Using household survey data, we find that adopting rooftop solar disproportionately harms low-income nonadopting households, whereas adopting electric vehicles disproportionately benefits them. This progressivity roughly offsets the regressivity of the electric vehicle subsidy transfers. |

| Abstract: | Highlights: • Simulated intercropping decrease disease intensity and improve protectiveness while canopy indicators predict such effects. • Pea intercropped with wheat decreased disease intensity compared with faba bean. • Nitrogen fertilization increased disease intensity. • This study stressed the critical lack of experimental data on disease in intercropping. Abstract: Context : Intercropping is a promising strategy for integrated disease management and agroecological transition, although experimental and modelling studies are scarce. Objectives: This study aims to understand and quantify the impact of non-host species choice and nitrogen (N) fertilization on disease epidemics in the context of intercropping. Methods: We collected existing experimental data on LAI based on a literature survey of non-diseased wheat intercropped with different non-host legume species (pea and faba bean) and N fertilization treatments. Based on a foliar epidemic model for intercropping, we simulated epidemics directly on these experimental data of LAI. The model is parameterized for two wheat fungal diseases: Septoria tritici blotch, a rain-borne disease, and wheat leaf rust, an air-borne disease. Results: Our results indicate that intercropping can decrease disease intensity and improve protectiveness for both diseases. Effect depends however on species choice as pea intercropped with wheat leads to lower disease intensity and better intercropping protectiveness compared with faba bean, whereas N fertilization increased disease intensity. We also found that crop indicators describing wheat leaf area index (LAI) can predict disease intensity, whereas indicators describing companion LAI can better predict intercropping protectiveness. Conclusions: Intercropping can significantly reduce fungal epidemics on wheat, and intercropping management practices can be optimized for effective disease management in wheat-legume intercrops. The dilution effect is more related to disease intensity, while the barrier effect is more related to intercropping protectiveness. Implications: These findings pave the way for identifying field indicators to predict epidemics. However, this study also stressed the critical lack of experimental data on disease in intercropping. |

| Abstract: | This paper contributes to the literature studying the effect of green nudges on the behavior of young people, particularly adolescents. We conducted a field experiment involving high school students to assess the effectiveness of a nudging strategy which aimed at motivating them to power off computers when these are not used in the classroom. Our nudging strategy resulted in a significant reduction in computer power in the treated high school compared to a control high school. We discuss the relevance of our work for research on young people's pro-environmental behavior as well as the implications in terms of policy-making. |

| Abstract: | Defining indicators to guide projects in the transition to the circular economy (CE) is currently a challenge. Indeed, there is neither comprehensive (offering a global representation of the circular economy) and transverse (relevant to several specific cases) indicators, nor a consensual definition of the circular economy. To identify what could indicators about CE represent and how, a database of 379 non-aggregated indicators have been developed, based on the literature. Categories of the database are dimensions of the CE that can be considered, and indicators are example of ways to represent them. A main question is then how to use this database to propose indicators adapted to specific contexts. According to studies in ecological economics, involving stakeholders in the production of indicators ensures their institutional anchor and pertinence for the specific context. A participatory tool-based method using the database has then developed, based on an existing participatory method (PARDI). Each step of the method is supported by tools, defined through workshops in a multidisciplinary academic project and literature study. The method aims to be generic (scale, context), while the set of indicators produced would be specific. Its capabilities were demonstrated through a project to set up a food processing industry in a specific context. |

| Abstract: | Using Croatian data and the IMF's Natural Disaster Debt Dynamic Tool, this paper assesses how public debt adjusts to extreme events in a small open economy. We compare debt paths under baseline and stress scenarios, the latter simulating a major earthquake in 2025. Croatia provides a unique setting for evaluating post-disaster recovery in countries recently incorporated into the European Union. Our benchmark projections, which assume moderate economic growth and a broadly neutral fiscal stance, suggest the debt-to-GDP ratio will gradually decline to below 55% by 2040. In contrast, in the disaster scenario, we document a sharp short-term increase and a persistent upward shift in the debt trajectory, reaching 75% of GDP. Deterministic and stochastic simulations allow us to assess the distribution of potential outcomes. It is shown that, in the absence of shocks, public debt is on a sustainable downward path, but a severe natural disaster could reverse this trend and keep it elevated for years. Our findings highlight the importance of fiscal buffers that are critical for creating space to absorb shocks. The paper innovates by integrating natural disaster stress-testing into public debt analysis, with implications for fiscal risk management and policy planning. While we focus on Croatia, the mechanisms we uncover have broader implications for small open economies exposed to extreme events. |

| Abstract: | One important factor in addressing climate change is the development and deployment of environmental-related, or green, technologies (GT). Environmental-related technologies are distinct, requiring specific conditions to be developed which vary depending on their relative level of technological maturity. Recent studies have focused on the role of migrant inventors in creating these conditions and spurring regional diversification into new technological domains. Regional diversification helps regions avoid lock-in and even escape fossil fuel dependencies. While the contribution of migrants to science and innovation is well documented, less attention has been given to migrants and diversification, especially in the case of GT and along the technological life cycle. In this study, we investigate the role of US-based migrant inventors in regional GT diversification using patent data from the USPTO between the year 1990 and 2012. We find that migrant inventors are positively associated with regional GT diversification, partly as a result of their previous patenting experience as well as the specializations of their countries of origin. With regard to the technological life cycle, while geographically diffused technologies rely on corresponding inventor experience, emergent technological diversification benefits from inventors from specialized countries. These findings highlight the bridging role that migrant inventors in international knowledge transfer and their importance in regional diversification in particular environmental-related technologies. |

| Abstract: | This paper develops a simple general equilibrium model with social capital accumulation. The representative household chooses how much time to allocate between work and social capital accumulation. Social capital generates satisfaction, but this satisfaction is affected by pollution. This paper considers two cases: (1) pollution reduces the marginal utility of social capital (social withdrawal effect) and (2) pollution increases the marginal utility of social capital (social engagement effect). Pollution, treated as a pure externality, is assumed to originate from production. In line with Pigouvian principles, the government introduces a proportional tax on production to finance depollution expenditures under a balanced budget rule. When preferences exhibit a social engagement effect or a weak social withdrawal effect, the economy has a unique steady state, which may experience a Laffer Curve. When preferences exhibit a strong social withdrawal effect, two steady states can coexist: one characterized by a high level of social capital and low consumption (voluntary simplicity steady state), and the other by a low level of social capital and high consumption (consumerist steady state). As in the case of a unique steady state, a Laffer Curve may emerge at the consumerist steady state but never at the voluntary simplicity steady state. However, the voluntary simplicity steady state always exhibits a Green Paradox, a phenomenon that never occurs at the consumerist steady state. Regarding the dynamics, the unique steady state that arises when preferences exhibit a social engagement effect or a weak social withdrawal effect is saddle-path stable. When preferences are described by a strong withdrawal effect, we prove that the consumerist steady state is also always saddle-path stable while the voluntary simplicity steady state is always locally indeterminate. |

| Abstract: | Typhoons are becoming more intense, destructive, and unpredictable due to global warming. Different from low-frequency disasters with single-impact nature (e.g., earthquakes and floods), typhoons exhibit cyclical risk patterns—frequent low-loss events interspersed with rare highly-destructive typhoons—which amplify vertical risk perception through availability heuristics. While previous studies on typhoon risk capitalization mainly focus on horizontal proxies such as flood zone maps, This study examines how typhoons' unique intermittent risk cycles reshape vertical housing price gradients through risk salience amplification. We introduce the “typhoon-induced vertical gradient”—greater price discounts on higher floors post-typhoon. We establish a risk capitalization framework that incorporates floor-level heterogeneity in high-rise structures to investigate the typhoon-induced vertical gradient and how this vertical gradient varies across different regions. The results reveal a typhoon-induced vertical gradient within the high-rises and the higher the floor level, the greater the vertical gradient is. We also hope to find that this vertical gradient would be more significant in the high-risk regions than in the low-risk regions. This gradient exhibits spatial self-reinforcement – high-risk regions demonstrate stronger effects than low-risk areas By formalizing cognitive constraints in vertical space pricing, this research bridges behavioral finance with urban economics. The findings provide insurers with floor-level risk premia models and inform climate-resilient zoning policies through 3D risk mapping. |

| Abstract: | El Foro de Ministros y Autoridades Máximas de la Vivienda y el Desarrollo Urbano de América Latina y el Caribe (MINURVI) es la principal instancia de coordinación intergubernamental de la región en materia de vivienda y desarrollo urbano sostenible. Sus Asambleas Generales constituyen espacios clave para el diálogo político, el intercambio de experiencias y la construcción de una visión común entre los países miembros, en alianza con organismos internacionales, banca de desarrollo, sector académico y sociedad civil. La XXXIII Asamblea General de MINURVI se llevó a cabo los días 12 y 13 de diciembre de 2024 en la ciudad de Belém do Pará, Brasil, bajo la presidencia pro tempore del Ministerio de las Ciudades de Brasil, liderado por el Ministro Jader Barbalho Filho, con el apoyo técnico de la Comisión Económica para América Latina y el Caribe (CEPAL) bajo su rol de cosecretaria técnica, junto con el Programa de las Naciones Unidas para los Asentamientos Humanos (ONU-Hábitat). Durante este encuentro, ministros, autoridades nacionales y expertos de toda la región abordaron el papel estratégico de la vivienda y el desarrollo urbano como motores para avanzar en inclusión social, la acción climática y la resiliencia territorial. Los debates pusieron en evidencia la necesidad de contar con información adecuada y actualizada para la toma de decisiones en políticas de vivienda, así como los desafíos específicos del desarrollo urbano en contextos ambientalmente sensibles como la Amazonía. Se destacó la importancia de garantizar el derecho a la ciudad como un principio fundamental de la Nueva Agenda Urbana, abordando la necesidad de construir ciudades más equitativas, accesibles y participativas. Asimismo, se subrayó el papel de la vivienda en la respuesta al cambio climático, tanto en la adaptación como en la mitigación, y se discutieron estrategias de reciclaje urbano y economía circular que promuevan un uso más eficiente del suelo y edificaciones, nuevos esquemas de financiamiento y una gestión urbana más innovadora y sostenible. El acceso a financiamiento adecuado y sostenido fue señalado como un elemento central para posibilitar estas transformaciones, permitiendo avanzar en proyectos que integren sostenibilidad ambiental, justicia social y desarrollo económico.

| Abstract: | This study examines mortality dynamics across major macroeconomic regions—Western countries, non-Western regions, and China—from 1960 to 2023, exploring variability and underlying drivers. Descriptive analysis shows that non-Western regions experienced the highest death rates in 1960–1990, followed by a marked decline as GDP per capita increased. China exhibited a similar pattern. Conversely, Western countries achieved only modest mortality reductions after 1991 despite sustained economic growth, even when controlling for population aging (≥65 years). Regression models and partial correlations indicate that economic progress initially correlates with mortality decline in all regions. However, in Western countries, this relationship reverses after 1991, forming an inverted-U curve when mortality is modeled against GDP per capita and elderly share. This suggests diminishing health returns and potential adverse effects of advanced development—such as environmental degradation, lifestyle-related diseases, and occupational risks. Non-Western regions, with slower economic acceleration, show no comparable reversal. Findings imply that beyond a development threshold, further growth may paradoxically elevate mortality. Policy strategies should prioritize balanced, sustainable development and integrated “One Health” approaches to mitigate health risks associated with over-rapid economic expansion. |

| Abstract: | Key messages AfCFTA and CAADP are Africa’s twin engines for structural transformation, but their success depends on deliberate alignment. While AfCFTA drives regional integration through trade liberalization, CAADP focuses on building resilient, inclusive, and sustainable agrifood systems. • There is strong strategic complementarity between the two frameworks, especially in goals related to competitiveness, private sector development, and integration of regional value chains. But alignment weakens at the level of implementation—risking policy incoherence and missed opportunities. • Tensions between AfCFTA and CAADP implementation exist around tariff liberalization, domestic policy space, and sector readiness, with risks that liberalized trade could outpace capacity of fragile agriculture sectors to compete, adapt, and benefit. • Food security, equity, and environmental resilience—central to CAADP—are recognized in AfCFTA objectives and justify certain exceptions yet remain only weakly embedded in its implementation protocols. • Institutional silos and fragmented infrastructure strategies could undermine coherence, with risks of trade and agriculture ministries, as well as regional and continental bodies, operating separately. • Strategic coordination, sequencing, and governance reform are essential. Alignment of AfCFTA and CAADP is not automatic—it must be designed, negotiated, and sustained to deliver on Africa’s transformation promise. • Bridging AfCFTA and CAADP is not a one-time alignment exercise but rather a strategic process of political, institutional, and analytical interaction that must be continuously revisited and actively managed if it is to deliver on the continent’s shared aspirations for prosperity, food security, and sustainability. |

| Abstract: | Against the backdrop of United Nations Office for Outer Space Affairs' (UNOOSA’s) 2025 Landmark Study, which documents women's 30 percent global workforce share in public space agencies—declining to 19 percent on boards—this paper applies gender budgeting framework to diagnose fiscal policy imperatives in the Department of Space (DoS), India. Aligning with the foundational principles of the UN Outer Space Treaty (1967), which mandates equitable benefits from space exploration "for all people, " and with Sustainable Development Goals (SDGs) 4 (quality education), 5 (gender equality), 9 (industry, innovation, and infrastructure), and 17 (partnerships for the goals), this analysis underscores the role of gender budgeting as a fiscal multiplier for inclusive growth in emerging space economies. Despite the absence of specifically targeted programmes for women in the space sector within the Ministry of Finance’s Gender Budgeting Statement 2025-26, our ex-post fiscal incidence analysis reveals that ISRO's significant achievements are inherently women-inclusive in their outcomes, despite workforce underrepresentation. We analysed the Space budgets across the space centres in India, and also across sanctioned Space projects to understand the fiscal incidence and marksmanship in space technology (e.g., launch vehicles, propulsion systems) and space applications (e.g., Earth observation, communication satellites). Key findings highlight marked variations in resource utilisation efficiency: utilisation rates ranged from a low of 10.9 percent at IN-SPACe—reflecting nascent private-sector integration challenges—to 21 percent at VSSC and 32 percent at URSC, where mature R&D pipelines drive higher absorption. Given the outcome of Space programmes including Earth Observation (EO) programmes and communication satellites for climate resilience have demographic than behavioural access, the units utilised patterns across income quintiles determine the fiscal incidence. Integrating results-linked gender budgeting into space policy thus emerges as a dual lever for equity—ensuring women's voice in high impact decision-making—and efficiency, by harnessing diverse perspectives to optimise resource allocation and innovation trajectories. |

| Abstract: | Climate change adaptation (CCA) increasingly relies on collaborative efforts to generate and circulate actionable knowledge. Among these, knowledge networks (KNs) have emerged as key infrastructures for fostering transnational cooperation, enabling mutual learning, and supporting local implementation. While their theoretical value is widely acknowledged, the empirical landscape of adaptation-related knowledge networks in Europe remains poorly understood. This article offers the first systematic mapping of KNs working on CCA in Europe, with a particular focus on Transnational Municipal Networks (TMNs)—a prominent subset composed primarily of local authorities. We identify and compare 32 knowledge networks across key dimensions including structure, governance, membership, funding models, and core activities. The analysis is grounded in two original datasets: a network-level dataset comprising 32 adaptation-related KNs and a membership-level dataset encompassing over 17, 000 entries, systematically collected and geo-referenced. These resources provide an unprecedented empirical basis for understanding how climate knowledge is shared, institutionalised, and mobilised across Europe. Our findings reveal a diverse and uneven landscape, with significant variation in access thresholds, support mechanisms, and geographic representation. TMNs, in particular, differ in the type and intensity of support they provide—ranging from technical expertise and financial assistance to symbolic capital and peer learning opportunities. The article contributes to ongoing debates about multilevel climate governance and the role of networks in enhancing local adaptation capacity. |

| Abstract: | This study examines the heterogeneous impact of flooding, if any, on housing prices, rental markets, and household financial conditions, with a particular focus on lower-income households in New South Wales, Australia. Using a Spatial Difference-in-Differences (SDID) approach to housing and household-level financial data, we assess changes in housing prices, rental markets, and household expenditures in flood-affected areas, focusing on the March 2021 flood event. Specifically, it examines its disproportionate effects, if any, on low-income households, particularly renters, for the first time. Our results reveal that while the direct impact on property sale prices is statistically insignificant, rental prices increased by 2.7% to 3%, with the most significant effect observed in the lower-end rental market. This can be attributed to supply shortages and landlords passing repair costs onto tenants. Specifically, owner-occupiers faced a significant rise in home repair and insurance expenses, while renters experienced increased housing costs without direct repair liabilities. Additionally, vacancy rates in flooded areas declined by 10.7% to 15.7%, with rental market pressures particularly affecting lower-income households. Results here suggest that lower-income households, particularly renters, were disproportionately affected by the flooding events. The study highlights critical policy implications, including improved flood risk awareness, better tenant regulatory protection, and integrating climate resilience into housing affordability strategies. |

| Abstract: | The resource curse hypothesis (RCH) has become one of the main lines of research in development economics. Based on a potential negative correlation between economic growth and the abundance (dependence) of natural resources, the RCH has generated thousands of articles and books. Most of these works used the time span of the years between 1970 and the present. Economic history has taken the hypothesis seriously, and in recent years, several studies with a long-term perspective have tested contemporary findings with mixed results. An analysis using longer time intervals has allowed us to have a better perspective of the relations between the abundance and dependence of natural resources on economic development. This work approaches this non-lineal relation using the most relevant economic history research on the topic. Moreover, a research agenda is suggested to enhance the input that Economic History could give to policy makers. |

| Abstract: | This preprint introduces the Authenticity Feedback Model (AFM) — a cyclic framework that quantifies perception–reality gaps in architectural sustainability, performance, and ESG legitimacy. The model integrates linguistic tone, stakeholder perception, and empirical performance validation to expose greenwashing patterns and reinforce authentic governance. Drawing upon decoupling theory, signaling theory, institutional legitimacy, and cybernetic feedback principles, AFM redefines how ESG performance can be continuously measured, verified, and corrected in real time.

| Abstract: | This essay argues for an integrative move in the investigation of the politics of ‘green’ finance. We suggest that approaching the politics of ‘green’ finance in the form of knowledge contestations can bring out complementarities and bridge divides between different levels of analysis and theoretical traditions. Our focus is motivated by the pivotal role of knowledge and ignorance in the organisation and governance of financial markets identified in economic sociology, political economy, and neighbouring disciplines. Drawing on this scholarship, we consider knowledge both a forum for and a means of politics. We then illustrate how this conceptualisation provides insights into the politics of ‘green’ finance on different levels of analysis and following different theoretical traditions: in the context of tracing elites in their dissemination of specific ideas shaping governance regimes; when following market devices which produce partial calculative representations of the world; in problematising how financial organisations both produce and accept certain types of knowledge to further their interests; and when examining the role of ideology and imaginative capture in stabilising financial capitalism during climate crisis. We conclude by identifying the connective tissue between these different analytical and theoretical approaches made visible by the integrative concept of politics as knowledge contestations. |

| Abstract: | Protracted conflict and climate shocks have profoundly disrupted food systems in northern Nigeria, yet little empirical evidence exists on how these shocks shape the functioning of the region’s food system (production, transportation, value addition, and trade). This study addresses this evidence gap by combining GIS-based mapping, cost structure analysis, and investment opportunities in food production, transportation, processing, and trade in key staple commodities across conflict-prone and climate-affected areas of northern Nigeria and connected market hubs. The analysis quantifies cost structures for key food supply chain actors, identifies systemic food system inefficiencies driven by conflict and climate factors, and examines how these factors undermine both commercial and humanitarian food flows. By integrating commodity-specific diagnostics with stakeholder perspectives, the study offers an evidence-based rationale for prioritizing interventions in conflict contexts. Two investment cases—on-farm storage and localized wheat milling—illustrate how targeted actions can reduce losses, enhance resilience, and create co-benefits for humanitarian operations and market recovery. By combining food-flow maps and cost structures for multiple actors along the food supply chain in a high-risk environment, and by demonstrating simplified approaches to linking empirical diagnostics with practical investment strategies, the study’s findings contribute to the literature on the functioning of food systems in conflict-prone and climate-affected contexts. In addition, the findings provide evidence to support policy changes, interventions, and investment decisions aimed at transforming food systems and addressing structural failures, while enhancing the efficacy of short-term humanitarian interventions. They also address the underlying causes of chronic food insecurity and support economic recovery in the region. |

| Abstract: | This paper employs an overlapping generations model to analyze how placing the burden of caring for both elderly parents and children on the working generation shapes fertility and other economic outcomes. In the model, fertility decisions create intergenerational spillovers. When one generation has fewer children, the next generation faces a heavier caregiving burden for its elderly parents, which in turn discourages childbearing. The model reveals sharply different long-run trajectories depending on the time intensity of caregiving. If care demands are moderate, sustainable growth remains feasible despite these externalities. However, when care becomes highly time-intensive, fertility declines, labor supply contracts, and the economy risks falling into a ``nursing hell, " where most time is devoted to caregiving. Policy measures, such as child allowances, can alleviate this dynamic by expanding the number of siblings and reducing the per-capita caregiving burden. Yet if care demands are extremely high from the outset, even such interventions cannot avert structural collapse. |

| Abstract: | A growing number of First Nations across Canada are entering into agreements with provincial governments to share revenues from natural resource extraction within their traditional territories. Yet, little guidance exists on the design of these Resource Revenue-Sharing Agreements (RRSAs). In this paper, we examine publicly available RRSAs to summarize their common components. We outline the decision points involved in structuring an RRSA and discuss potential benefits and drawbacks for First Nations considering entry. |

| Abstract: | This study investigates the empirical link between environmental, social and governance (ESG) reporting and the financial performance of Real Estate Investment Trusts (REITs) across a developed market (USA) and a developing market (South Africa). ESG reporting on REITs remains underexplored in developing countries (Newell & Marzuki, 2022), which brings into question the level of sustainability and degree of financial optimization of these REITs (Naeem, Cankaya & Bildik, 2022) . This study will investigate whether the financial performance of REITs has any correlation to ESG reporting, or whether it is solely subject to the market conditions around it. The research will provide answers to the questions, (1) “Does ESG reporting in REITs of developing countries result in greater financial performance?” and (2) “If ESG-rated REITs are performing better, by what margin are they doing so in developed countries in comparison to developing countries?”. To find the answer we will use cross-sectional regression analysis to compare four datasets across a ten-year period from 2013 to 2023, namely: The top 10 REITs in the USA and South Africa, and the top 10 ESG-rated REITs in the USA and South Africa (decided by largest market cap). The study will not be looking into the specific components of ESG, but rather ESG reporting as a whole. We expect to find that in both the USA and South Africa, the ESG-rated REITs have a greater financial performance, but we are unable to speculate by what margin they outperform the others by, and if that margin was the same across both countries. |

| Abstract: | Recent evidence has shown that, in the context of participation decisions in Payment for Ecosystem Service schemes, land managers’ choices are determined by a wider set of factors than the literature has traditionally focused on and could, furthermore, be influenced by cognitive biases (Clot et al 2014; 2015, 2017a). This wider set includes the extent to which people care about their neighbour’s wellbeing, or the behaviour of “relevant others” (Kuhfuss et al., 2016); and farmers’ concerns for environmental outcomes (Kuhfuss et al., 2022). Assessing this complex set of preferences is difficult (Clot et al. 2017 b). In this paper, we present a method for estimating time, risk, social and environmental preferences simultaneously using incentivized choice experiments. This approach builds on work by Ida and Goto (2009). We test our new method in the lab, comparing our results with “standard” survey questions. This exercise is repeated in two time periods where the relative income of student participants varies – before and after they receive annual stipend payments – to capture changes in relative poverty. We show that our new method produces results that are consistent with standard survey-based questions at the aggregated level for risk preferences. Moreover, we find robust evidence that individuals are less risk averse when relatively wealthier. |

| Abstract: | As trade policies and other US federal actions attempt to reshape global critical mineral markets, concerns about the resilience of supply chains for strategic civilian and military technologies will continue to assume a large role in policymaking. This report addresses the supply chain for lithium-ion batteries and evaluates the limits of resource nationalism, an approach to policymaking that entails greater government intervention in the resource economy, to bolster US mineral production and processing capacity. We first discuss recent executive actions, tariffs, and defense-led partnerships and then assess US lithium, cobalt, and nickel resources, as well as processing costs, considering potential electric vehicle demand through 2050. We conclude that the national interest is best served by structured international cooperation with selective domestic expansion, given fundamental resource availability constraints, long lead times for new mines, and the high costs of geographically diversifying processing capacity. This report presents cost estimations and weighs policy options for decisionmakers seeking to address Chinese market power in the material foundations of battery technology. |

| Abstract: | One of the surprising features of modern economic growth is that economies with abundant natural resources have tended to grow less rapidly than natural resource-scarce economies. In this paper we show that economies with a high ratio of natural resource exports to GDP in 1971 (the base year) tended to have low growth rates during the subsequent period 1971-89. This negative relationship holds true even after controlling for variables found to be important for economic growth, such as initial per capita income, trade policy, govern ment effciency, investment rates, and other variables. We explore the possible pathways for this negative relationship by studying the cross-country effects of resource endowments on trade policy, bureaucratic effciency, and other deter minants of growth. We also provide a simple theoretical model of endogenous growth that might help to explain the observed negative relationship. |

| Abstract: | We assess influences on electric heat pump adoption with household data from the American Housing Survey covering 2017-2023, with implications for sustainable and affordable energy transitions. Substitutability for heating is important, motivating our comparative and multinomial logit analysis. A key attribute of our analysis is including prior energy contexts at the household level, such as the prior main heating type and whether the household previously used natural gas for any purpose. We find that existing housing contexts are crucial, with lower likelihood of electric heat pump adoption for households with warm air furnaces as their prior primary heat source, those using natural gas for any purpose, apartments, and old dwellings. Economic influences are less obvious for electric heat pumps compared to some other technologies. However, we conduct interaction analysis to show that income likely has an influence on electric heat pump adoption. Policymakers should therefore still consider equity across economic distributions. The more complicated context of heat pump adoption, with existing substitutes already being widely used, implies that policies need to be flexible to support households when they are ready to make heating investments. |

| Abstract: | Agricultural crop production and its impacts on natural resources often varies strongly in space. As farmers’ responses to climate or price changes may equally differ substantially between locations, spatially explicit knowledge on crop yield, cropping decisions, and their drivers are required to project future crop production and to design effective policy interventions. However, existing agri-economic supply models are incapable of simulating field-level input intensity or yield, mainly because observations for these variables are almost never available for individual fields. Here, we present an approach to estimate the parameters of a structural, field-level crop production model for yield, variable input, and crop choice modeling using widely available data. Our approach evolves around two methodological contributions: First, we conceptually and statistically link variables at different levels of spatial aggregation, specifically observed cropping decisions, biophysical conditions and regional statistics. Second, we show how parameters occurring in multiple structural equations can be simultaneously estimated with Bayesian Probabilistic Programming. We first demonstrate with synthetic data that our approach can recover true model parameters. We then exemplarily apply it for a German federal state and simulate the impacts of an output price increase on expected field-level production quantity changes of wheat, barley, and grain maize. |

| Abstract: | This study investigates the impact of mandatory energy performance certification (EPC) disclosure on housing market dynamics in France. Building on a phased implementation of disclosure policies since 2006, the 2021 regulation introduced legally binding EPC visibility in advertisements alongside significant penalties for non-compliance. Using a (i) difference-in-discontinuity framework that exploits cross-border policy variations between France and Belgium and (ii) an event study design exploiting the heterogeneous effect of the regulation, the study accounts for spatial and temporal variations in policy adoption and identifies the causal effects of this policy on property prices. The analysis reveals three key insights. First, energy-inefficient properties (EPC ratings F or G) faced price declines up to -9 percentage points (pp) under mandatory disclosure, signaling a market penalty for inefficiency. Second, efficient properties experienced modest price gains, with houses showing a +3pp increase. Third, the regulation surprisingly fostered strategic nondisclosure, particularly in apartment market, where missing EPC ratings garnered a +14pp price premium four years after enactment. These findings highlight the heterogeneity of market responses across property types and locations. The study concludes by discussing the social welfare implications of mandatory disclosure, including improved affordability for certain buyers, risks of eviction due to price increases, and potential misreporting behaviors. By advancing the understanding of energy efficiency’s role in housing markets, this research offers actionable insights for policymakers seeking to balance climate goals with equitable market outcomes. |

| Abstract: | Wildland-Urban Interface (WUI) fires represent a compound disaster resulting from the interactions between natural ecosystems and human settlements, characterized by significantly dynamic evolving risks. However, most current risk assessment studies are based on static frameworks, which struggle to effectively capture the dynamic changes in risk over time. To address this issue, this paper proposes an innovative method that integrates a dynamic evaluation matrix, grey incidence analysis, and an optimization model for the dynamic risk assessment of WUI fires. This method incorporates time-series data by constructing a dynamic evaluation matrix, subsequently calculates the weighted standardized matrix for each evaluated area and its local volume matrices relative to the positive and negative ideal matrices. The dynamic differences between the evaluated areas and the ideal state are quantified by calculating the grey incidence degree, and an optimization model is established to solve for the superiority degree used for risk ranking. Research demonstrates that this method not only simplifies the computational process but also effectively captures the dynamic evolution patterns of fire risk across different areas, enabling refined risk classification. Compared to existing static methods, this framework overcomes their limitation in adequately representing risk dynamics, providing a more scientific basis for decision-making in the dynamic management and proactive prevention and control of WUI fires. |
