| Abstract: | Reducing environmental damage from agricultural systems is a critical priority for governments. Particularly, rice farmers in developing nations frequently resort to the environmentally harmful practice of post-harvest residue burning. Promotion of practices to mitigate burning is met with differing degrees of success. Through experimental research with farmers in Thailand, this study examines the impact of temporary cost and income subsidies on the reduction of burning by farmers with differing financial attributes. Financial characteristics were modelled by imposing budget constraints on participants through varying initial endowments. The findings indicated that temporary subsidies were effective in not only the short-term during provision but also in the longterm after subsidies ended. Additionally, several psychological impacts contributing to disparities in adoption rates were identified, including the perceived need for obtaining more income among budget-constrained individuals and the noteworthy impact of loss aversion on long-term adoption decisions. The study’s insights offer valuable contributions to understanding smallholder farmers’ behaviours in accepting temporary subsidies for sustainable agriculture and provides policymakers with practical strategies to alleviate the harmful consequences of conventional farming practices. |

| Abstract: | The relationship between wine products and the concepts of quality, identity, place, typicality and terroir is rooted in a deep socio-cultural and agricultural connection. Today, that bond, once considered incontrovertible, is increasingly at risk of weakening or fading due to the impacts of Climate Change. In light of this, our study aims to explore wine growers' perceptions of these effects and examine the adaptation strategies, both planned and already implemented, chosen by winegrowers. The phenomenon was investigated at both national and regional levels in two of the world's most significant wine-producing countries, namely France and Italy, focusing specifically on producers in the Languedoc-Roussillon and Tuscany wine regions. Data were collected through semi-structured interviews with twenty-three wine producers, revealing a high level of awareness regarding the severe climatic impacts, with coping strategies varying by region. However, these adaptive approaches often conflict with the rigid product specifications of the designations of origin, which have remained largely unchanged over time, showing limited flexibility in response to an evolving climate, society and market. In this context, the study underscores the urgent need for dynamic regulatory frameworks to support the adaptation efforts and measures developed by European wine producers. |

| Abstract: | Food and nutrition security in Bangladesh is a multifaceted issue encompassing four fundamental dimensions: availability, access, utilization, and stability. Each dimension is influenced by various determinants, including economic factors, social conditions, and governance structures. This study examines key indicators of poverty and food insecurity in Bangladesh as of 2024, highlighting the dietary practices across different demographic groups. Detailed analysis of the consumption of ten food groups over a seven-day dietary recall reveals distinct patterns among adolescent girls and boys, adult women and men, and elderly populations differentiated by place of residence. Despite progress, trends indicate persistent undernutrition among children and fluctuating BMI levels among Review Article ever-married women over time. From 2014 to 2023, the agricultural sector exhibited growth in value added, alongside a significant share of rural households engaged in livestock and poultry production. The study further explores projections indicating a rise in total food consumption from 2015 to 2030, juxtaposed with the escalating cost of a healthy diet, posing affordability challenges for vulnerable populations. Coping strategies employed by households often involve unsustainable practices that threaten long-term food security. Key nutrition indicators underscore ongoing challenges while strategic developments in 2024 reflect concerted efforts to improve nutrition outcomes. The average dietary energy supply adequacy over recent years provides additional context on national nutrition status. |

| Abstract: | Aquaculture likely plays an important role in future diets, yet the potential of aquaculture to upcycle biomass and supply nutrients in circular food systems remains largely unstudied. Under the circularity paradigm, animal production is constrained by the availability of so called low-opportunity-cost feed (LCF). Aquaculture species differ in their ability to convert LCF into food, and the implication for nutrient supply in food systems are unclear. In this paper we explore the specific role of aquaculture to upcycle LCF into valuable food for humans in Europe using the resource allocation model FEEDSOM (FEED Systems Optimization Model). We provide insight into what nutrients aquaculture can supply to the human diet, how much aquatic food can be produced when animals are fed exclusively with LCF, and what LCF can be recycled into fish feed. We selected Atlantic salmon, European seabass and common carp, produced in multiple productivity levels, to represent European aquaculture. Carnivorous aquaculture species can play an important role in circular food systems by upcycling eicosapentaenoic (EPA) and docosahexaenoic (DHA) from fisheries by-products. However, their dependence on fisheries by-products to supply EPA/DHA also limits their capacity to expand. Omnivorous aquaculture species do not rely on fisheries to supply EPA/DHA, but their overall contribution to EPA/DHA supply is relatively low. We found that under current aquaculture production and consumption in Europe, we cannot supply enough EPA/DHA for the European population. To reduce the nutrient gap of EPA/DHA, we can either increase aquaculture or eat more edible parts of the fish (both fish from aquaculture and fisheries). However, expanding aquaculture should not be the priority, as this requires more LCF, production area, and puts pressure on the environment. Eating more edible parts of the fish can provide enough nutrients, including EPA/DHA, to meet the demand of the European population and help feed an additional 118 million people outside Europe. |

| Abstract: | In early March 2026, Iranian retaliation against U.S.-led military operations halted commercial shipping through the Strait of Hormuz, driving urea spot prices up 28.2% and farm diesel prices up 34.7% within three weeks. This brief assesses the profitability impact of this dual fertilizer and fuel shock on North Dakota corn, soybean, and wheat producers using updated 2026 NDSU Projected Crop Budgets and a March 2026 producer survey. The shock arrived when corn and wheat margins were already negative at −$27.60/acre and −$33.41/acre, respectively, a substantially weaker starting position than at the onset of the 2022 Russia–Ukraine conflict. Under full exposure, the combined shock adds $31.70/acre for corn, $21.18/acre for wheat, and $5.12/acre for soybeans, with current commodity price responses insufficient to offset these increases on any crop. Corn bears the largest burden through the nitrogen channel; soybeans, though largely insulated from fertilizer costs, face margin erosion through diesel. A producer survey finds that pre-purchase timing partially buffers fertilizer exposure for many operations, but fuel costs remain fully exposed regardless, and more than half of respondents reported outstanding spring fertilizer purchases. Unlike 2022–2023, when commodity prices eventually exceeded rising input costs, the 2026 Hormuz shock combines a weaker margin baseline with a commodity price response that has so far fallen well short of restoring profitability. |

| Abstract: | We examine the impact of rural road connectivity on economic and novel governance outcomes in the context of the world’s largest rural road program, India’s PMGSY. Using a novel village-level survey designed around PMGSY’s rollout, we exploit quasi-random variation in road placement to estimate causal effects of connectivity on agricultural and labor markets as well as governance and political connectivity. We find evidence that roads support market access, as local producer prices increase by 1.3 SD and agricultural outputs diversify. Despite the improved agricultural output prices and options, labor shifts away from agriculture to casual work, suggesting improved non-agricultural market access. Interestingly, increases in casual labor are almost exclusively local to the connected village, and we find a decrease of short- and medium-term migration by 0.8 SD. Additionally, road connectivity increases local state presence, with a 1.1 SD increase in an index of official government visits and a 0.9 SD increase in an index of political connectivity, and leads to higher wages on government construction projects and lower prices in government shops. Our findings show that road leads to more vibrant and diverse rural economies. |

| Abstract: | -Background- The world is facing a severe drug crisis, posing serious public health and societal risks. Yet, little is known about drug use among farmers and farmworkers, key contributors to global food production. Poor mental health and precarious working conditions in agriculture are common. Farmers and workers may turn to drugs to cope with these conditions, however, evidence on drug use in agriculture is extremely limited. A challenge in collecting such data is social desirability bias stemming from the topic's sensitivity. We address this gap by using sensitive question techniques and offer novel evidence on drug use among farmers and farmworkers, highlighting links between working conditions, work-related health, and drug consumption. -Methods- We conducted item-count and item-sum double list experiments with 1, 554 farmers and workers to measure the prevalence and frequency of drug use in Nigeria's labour-intensive tomato sector where the topic is highly relevant. List experiments avoid direct questioning and can estimate sensitive behaviours, while hiding respondents' answers from the interviewer. Using these estimates, we ran multivariate regressions to identify work-related risk factors of drug use, focusing on burnout, work-related pain and health problems, pesticide exposure, unusual working hours, and belief in work performance effects. -Results- The item-count experiment suggests that about 8% of farmers, 20% of seasonal workers, and 6% of casual workers used drugs in the previous 12 months. The item-sum experiment finds that drug-using farmers and seasonal workers have consumed drugs on about 8 days in the last month on average (farmers possibly more than that), and drug-using casual workers on 7 days. Multivariate regressions show that work-related pain and belief in performance-enhancing effects are the most important risk factors for frequent drug use. Our results also demonstrate that burnout levels are significantly higher among farmworkers than among farmers, but we do not find a significant association between work-related burnout and drug use. -Conclusions- Farmers and farmworkers suffer from important occupational health deficits. Drug use and mental health in rural areas in particular remain underappreciated on policy and research agendas. Implications for agricultural productivity and rural development should be further explored. |

| Abstract: | This paper investigates critical success factors for managing multi‐actor research partnerships for sustainable food systems along their lifecycle. Such partnerships coordinate both internal activities and manage externally funded projects. Drawing on evidence from case studies and workshops with diverse experts, the study identifies critical success factors for distinguishable development and operational phases, core pillars, and management categories for supported research projects. Guiding principles like adaptability, trust, transparency, consensus, and proactiveness are essential for ensuring inclusiveness and sustainability‐orientation. Additionally, successful partnership management depends on key performance indicators, in critical success factor represented areas, for continuous coordination and management, monitoring and reporting, and coherent communication, dissemination, and exploitation. Based on these unique expert‐driven insights, a novel conceptual Modus Operandi framework is developed, contributing to knowledge on research partnership management. Once validated in different contexts, this framework can support project managers and policymakers in effectively managing and guiding food system research partnerships. |

| Abstract: | Agricultural pricing policies are crucial for farm profitability and food security in India. This study analysed how input and output prices significantly influence the profitability of cereals in Karnataka, with the strategic support prices playing a crucial role in maintaining the price parity. The average annual TFP growth was 1.041 per cent. Rising input costs, particularly for human labour, led to reduced profitability for Jowar (6.12 per cent) and Ragi (4.89 per cent). The net effect was adverse for Jowar (-1.50 per cent) and Ragi (-0.86 per cent) due to rising input costs outpacing output prices. The study recommended increasing the MSP for Jowar (60 per cent) and Ragi (46.24 per cent) above the existing levels. A strategic price adjusted for changing input costs can stabilise farm incomes and promote sustainable production, enabling efficient pricing policies. |

| Abstract: | Insect farming is rapidly emerging as a sustainable alternative to conventional livestock, praised for its lower environmental impact and potential to enhance food system resilience. Yet, the ecological risks of large‐scale insect cultivation remain underexamined—especially the threat of biological invasions following unintentional escapes. This synthesis examines current knowledge of invasion pathways from both terrestrial and aquatic farming systems, drawing on the well‐documented case of aquaculture to identify lessons for the insect farming sector. We highlight shared risk factors across sectors, including the widespread farming of species with invasive traits, production outside native ranges and insufficient management frameworks. Aquaculture of crustaceans, as a close taxonomic and ecological analogue, illustrates how poorly managed industrial growth can result in significant ecological and economic costs. Policy implications : We argue that preemptive risk assessments, species screening and transferable, adaptive regulatory frameworks developed for aquaculture offer a critical foundation for safeguarding against insect‐driven invasions. Proactive governance that embeds these safeguards before large‐scale expansion offers a rare opportunity to prevent invasion outcomes observed in other farmed taxa and to guide the insect farming sector towards genuinely sustainable growth.

| Abstract: | This paper examines the impact of upstream deforestation on water coverage and burned area in wetlands. Using a panel dataset of satellite-derived land cover for multiple hydrographic basins, we analyze this relationship in the Brazilian Pantanal from 1985 to 2023. We find that a 1% increase in upstream deforestation reduces water coverage by 0.51% and increases burned area by 0.55% per year. The effect of upstream deforestation on downstream burned area generates an emissions multiplier, as carbon released through deforestation is compounded by emissions from downstream burned area. On average, for each ton of carbon emitted due to deforestation, an additional 0.14 tons are released through downstream fire. |

| Abstract: | This article presents a long-run estimate of total factor productivity (TFP) in Uruguayan agriculture for the period 1870–2016. Drawing on a growth accounting framework and the construction of a new historical dataset, it provides homogeneous and consistent estimates of TFP for the agricultural sector as a whole and for its main subsectors: crops and livestock. The analysis situates productivity dynamics within the broader trajectory of national development, highlighting the interaction between technological change, institutional arrangements, and international integration. The findings identify three interrelated long-term patterns: cycles of modernization associated with waves of technological adoption and external integration; prolonged episodes of adaptive stagnation, during which growth relied primarily on the extensive use of natural resources; and alternating sectoral divergence between crops and livestock, linked to differentiated technological and institutional regimes. Overall, agricultural TFP grew at an average annual rate lower than 1% between 1870 and 2016, reflecting a discontinuous path of innovation rather than a linear process of progress. Efficiency gains materialized when institutions, policies, and markets were coherently aligned, and stalled when such conditions weakened. By combining long-run TFP measurement with historical interpretation, the paper contributes to a deeper understanding of the structural determinants of agricultural productivity and of the role of the agricultural sector in Uruguay’s economic development. |

| Abstract: | Intergovernmental targets are reinforcing the need for more sustainable fisheries and more effective marine conservation. It is now urgent to understand how area-based conservation and sustainable fisheries management tools contribute to these environmental and socio-economic goals. Here, we systematically reviewed and assessed the outcomes of marine protected areas (accounting for their level of protection and of enforcement), fisheries restricted areas, and fishing effort reduction measures in the Mediterranean Sea, using 11 ecological and economic indicators. We show that commercial species in general, and fish species in particular, showed the highest proportion of positive to neutral effects in response to the management tools assessed compared to non-commercial and benthic assemblages. Among the management tools, partially protected areas showed the lowest proportion of positive to neutral effects compared to fully protected areas, and to the other management tools. Partially protected areas and fully protected areas showed higher neutral to negative ratio than fishing effort reduction measures overall. Within MPA protection levels with high enforcement, fully protected areas outperformed minimally protected areas, based on the higher positive to neutral effects ratio. Our results further underscored the critical role of enforcement, particularly for fully protected areas, which were found more beneficial overall under high enforcement than medium enforcement (based on positive to neutral effects ratio). Our findings support the prioritisation of well enforced fully protected areas and the integration of fisheries management and conservation objectives in marine spatial planning to effectively achieve regional and global sustainability goals for the ocean. |

| Abstract: | This paper quantifies agricultural performance in Latin America in the early 20th century, complementing previous qualitative studies with a comparative and historical perspective. The analysis covers ten countries –Argentina, Brazil, Colombia, Chile, Cuba, Mexico, Nicaragua, Peru, Uruguay, and Venezuela– during the years preceding World War I. We identify three broad agrarian paths. Argentina and Uruguay featured extensive, high-productivity, export-oriented systems that promoted broader economic development. Chile, Cuba, and Nicaragua exhibited more intensive but labour-demanding systems, with moderate productivity and uneven technological progress. Venezuela, Mexico, Colombia, Brazil, and Peru maintained low-productivity, traditional agriculture with limited potential for economic growth. These contrasting structures highlight the diversity of Latin American agrarian capitalism and help explain the uneven capacity of national economies to initiate structural transformation. Overall, differences in factor endowments played a decisive role in shaping productivity patterns, with land-abundant regions favouring labour-saving technologies. |

| Abstract: | The energy transition depends not only on building renewable capacity but also on protecting the natural resources on which renewables rely. This paper shows that conservation and renewable policies are complements. We quantify how Amazon deforestation affects Brazil's electricity market by reducing rainfall and hydropower generation. We model the transmission chain from deforestation to atmospheric moisture, to downwind rainfall, to river discharge and hydro output, and embed the resulting supply shift within a market-equilibrium framework. Counterfactual simulations indicate that reversing all deforestation since 1985 would increase annual hydroelectric output by 13 TWh, lower electricity prices, and generate welfare gains of USD 1.1 billion per year. These gains are unevenly distributed: consumers benefit from lower prices and Amazon-basin hydropower producers benefit from higher output, while thermal generators and hydropower producers elsewhere lose. Finally, we identify small, high-leverage regions that account for a disproportionate share of hydropower value, informing targeted conservation and restoration. |

| Abstract: | Climate change damages vary across countries, because of regional variation in climate metrics like temperature and regional variation in economic exposure. This is evident in the breakdown of the social cost of carbon: the country social cost of carbon (CSCC). While for the former a large amount of estimates exists, only few studies provide information on the per country breakdown and among those few, empirically- derived estimates do not well align with model-based derived estimates. Here, we derive a new set of CSCC estimates consistent with macroeconomic growth theory which align with model-based estimates. We obtain a median estimate for the SCC of US dollars (US$) 167 per tCO2 (2020 prices, 66% CI: 39 to 312) for our main specification. India has the highest median CSCC (US$50 per tCO2 with 66% CI: 26 to 80), resulting from a relatively high GDP and relatively high projected temperature. Furthermore, we apply the CSCC estimates to assess the wealth contributions resulting from carbon sequestration in land ecosystems globally, nationally, and across borders. Countries both contribute to and benefit from sequestrationelsewhere, which is particularly relevant for designing payment schemes. Under a global agreement, Brazil for example would receive median US$202 ha-1 yr-1 for forest protection.

| Abstract: | Motivation The high level of regulation has a strong influence on the development of Ethiopia's export- and domestic- oriented coffee value chains, as well as on their ability to participate in Global Value Chains and in domestic value chain development. The fact that Ethiopia's coffee value chains are further differentiated along various dimensions is widely overlooked in the scientific literature. Approach and methods Drawing on expert interviews and other data sources, we identify, describe, and discuss the structure and organisation of the Ethiopian coffee value chains, taking into account institutional conditions and policy frameworks. We also identify relevant institutions and policies involved in these value chains across primary, secondary, and tertiary markets, along with their respective interventions. Findings Our analysis identified four major coffee value chains: formal, informal, domestic, and international chains. Stakeholders' competing goals and conflicts have created a complex structure, as exemplified by the strict market regulations in place. Reforms, such as Ethiopia's monetary policy, have caused foreign exchange and FDI deficits, impacting the coffee sector, which remains the primary source of foreign currency but limits domestic coffee development. This also spurred informal trade for local and cross-border markets. An overvalued currency and cheap imports attract informal traders, as exporters seek foreign currency through coffee, thereby hindering the sector's development. Poor quality control further restricts the competitiveness of domestic chains, favouring small, inefficient, and informal traders. Institutions failed to regulate reforms, such as the 2018 coffee reform, which reduced transparency and undermined trust. Furthermore, the failure of institutions to monitor and regulate policy reform meant that farmers, primary cooperatives, and traders working on quality considered it a less rewarding activity. The Ethiopian coffee market does not function effectively in terms of differentiating and remunerating different product and process qualities. Policy implications The results highlight the need to implement quality control measures at farm level, particularly within the farmer-supplier-exporter chain, in order to utilize the country's potential to produce high-quality coffee for export and develop the domestic value chain. This also calls for designing a system that rewards quality production at all stages of the value chain. Acknowledging the distinct coffee value chains in the country and creating a strategy that considers their variations is crucial. |

| Abstract: | Climate change is reshaping the economic environment in which households make decisions, generating diverse adaptive responses and increasing the need for data that can guide effective policy. Yet current measurement efforts remain fragmented, reflecting two key gaps: limited systematic data on household adaptation and the lack of a structured framework to interpret it. This paper addresses both by developing a literature-informed framework for diagnosing household-level climate adaptation, focusing on adjustments in income-generating activities as a primary response to climate risk. The framework follows four stages: mapping income streams, assessing exposure, identifying feasible responses, and analysing take-up alongside the constraints that limit adoption. It integrates both objective and subjective dimensions of exposure, recognising the role of perceptions, beliefs, and information. By situating decisions within broader institutional and economic contexts, the framework can inform survey design, improve diagnosis of adaptation gaps, and generate more policy-relevant and comparable data to support efforts to scale effective adaptation and strengthen household climate resilience. |

| Abstract: | One of the main arguments for implementing public works programmes (PWPs) instead of other social protection schemes such as cash transfers is that the assets created through these programmes themselves can generate medium- to long-term benefits. This is particularly important as the costs for supervision and the construction materials can account for up to 70 per cent of programme budgets. Despite this, there is scarce empirical evidence on PWPs' effects through the "asset channel": indeed; most studies have focused solely on the traditional "wage channel". To bridge this gap, this paper examines whether and how assets created under Malawi's Climate-Smart Enhanced Public Works Programme (CS-EPWP) - a programme recently implemented by the government of Malawi and funded by the World Bank - strengthen the resilience of households to climate shocks such as droughts and floods. The paper relies on case study analysis using primary qualitative data based on focus group discussions and key informant interviews with different stakeholders at the national, district and community levels. Interviews were conducted during fieldwork in September 2024 in two southern districts of Malawi highly affected by climate change. The analysis is complemented by site visits and quantitative survey data on asset quality. By combining these methods, we find that the CS-EPWP generates durable, community-maintained assets, which in turn enhance households' capacity to cope with and adapt to climate shocks. In particular, land-based assets provide multiple benefits for both households and communities, while forest-based interventions are expected to generate similar long-term gains, though further research is needed to confirm their (long-term) impacts. To maximise the impact of climate-smart public works programmes, policymakers and donors should align asset creation with climate objectives and adopt participatory approaches to ensure their relevance, maintenance and long-term sustainability. |

| Abstract: | This article examines the legal responsibility imposed on livestock farmers in the Luilu territory, Lomami Province, Democratic Republic of Congo, in relation to the prevention of zoonotic diseases. Drawing on a mixed-methods approach—combining legal analysis, qualitative surveys, and participant observation—it identifies the concrete legal obligations of farmers, their lack of awareness in practice, and the persistence of informal practices. The findings highlight that the law is only partially applied on the ground, which undermines effective prevention. The study therefore underscores the necessity of strengthening responsibility through a multisectoral One Health approach, integrating human, animal, and environmental health into a unified framework. |

| Abstract: | European climate policies largely target territorial emissions, overlooking greenhouse gas (GHG) emissions and raw materials embodied in international trade. This study quantifies the potential and limitations of a sufficiency-oriented national strategy to reduce these impacts from a consumption-based perspective. Using the MatMat Environmentally Extended Input-Output (EEIO) model, we assess France's transition pathways toward Net Zero Emissions (NZE) by 2050 under two scenarios: an Efficiency-driven (Eff.) and a Sufficiency-oriented (Suff.) one. Results show that sufficiency systematically outperforms efficiency by reducing both GHG emissions (-44% vs. -31%) and raw material extraction (-24% vs -4%). Its outperformance stems from its stronger ability to reduce import dependency and to shift demand towards less material-intensive production. Housing, mobility, and food drive most reductions, while final services remain a persistent blind spot. In 2050, about twothirds of France's consumption-based impacts remain embodied in imports, 75% of which originate outside the EU, limiting the leverage of European decarbonization policies. These findings highlight the upstream mitigation potential of sufficiency and the need to extend NZE strategies beyond territorial scopes. Two key implications emerge. First, extending sufficiency to service provision is crucial to limit rebound effects and address the growing role of services in ageing societies. Second, integrating sufficiency into coordinated EU-level trade, industrial, and resource policies is essential to tackle imported pressures and strengthen the resilience of low-carbon transitions. |

| Abstract: | • In March 2026, the Strait of Hormuz is closed. The shutdown blocks roughly one-fifth of the world's oil and one-quarter of its liquefied natural gas, triggering severe welfare losses in energy-dependent developing countries worldwide. • Standard trade models underestimate the impact because they miss the bottleneck mechanism: energy disruptions cascade through chemicals and fertilizer production into food prices, amplifying losses for the world's poorest countries. • Developing countries that depend on imported energy and fertilizers-particularly in South Asia, sub-Saharan Africa, and the Middle East-face the steepest food price increases and welfare losses. The aggregate global costs are moderate, but the burden falls disproportionately on the world's poorest: the USA loses just -0.07%, while countries in South Asia and Africa face losses 10-20 times larger. • A prolonged closure allows some market adjustment, but structural damage persists-and the timing during peak Northern hemisphere planting season compounds the food security risk. |
| Abstract: | • Im März 2026 ist die Straße von Hormuz geschlossen. Die Sperrung blockiert rund ein Fünftel des weltweiten Öls und ein Viertel des Flüssiggases, mit schweren Wohlfahrtsverlusten für energieabhängige Entwicklungsländer weltweit. • Standardmodelle unterschätzen die Auswirkungen, weil sie den Engpassmechanismus übersehen: Energiestörungen pflanzen sich über die Chemie- und Düngemittelproduktion in die Lebensmittelpreise fort und verstärken die Verluste der ärmsten Länder. • Entwicklungsländer, die auf importierte Energie und Düngemittel angewiesen sind-insbesondere in Südasien, Subsahara-Afrika und dem Nahen Osten-sind am stärksten von Nahrungsmittelpreissteigerungen betroffen. Die globalen Kosten sind moderat, doch die Last trifft die ärmsten Länder überproportional: Die USA verlieren nur -0, 07%, während Länder in Südasien und Afrika 10- bis 20-mal höhere Verluste erleiden. • Eine längerfristige Sperrung ermöglicht gewisse Marktanpassungen, doch die strukturellen Schäden bleiben bestehen-und der Zeitpunkt während der Hauptaussaatzeit auf der Nordhalbkugel verschärft das Ernährungssicherheitsrisiko. |

| Abstract: | This paper analyzes the structuring of alternative food systems, which emerged in response to the shortcomings of industrial agriculture and are driven by citizen-led and entrepreneurial initiatives. Initially marginal, these initiatives are now organized into networks that can be understood as meso-critical spaces. Drawing particularly on the concepts of frame and framing, the article examines how actors collectively construct the futurity. Through a longitudinal study (2008–2024) focused on the Lyon case, it shows that these framings, sometimes coherent, sometimes ambivalent, influence the meso-critical space's capacity to structure itself and transform practices. The central challenge lies in maintaining their alternativity, constantly threatened by processes of hybridization or isomorphism with the conventional model. |
| Abstract: | Ce texte analyse la structuration des systèmes alimentaires alternatifs, nés en réaction aux dérives de l'agro-industrie qui sont portés par des initiatives citoyennes et entrepreneuriales. Initialement marginales, ces initiatives se structurent aujourd'hui en réseaux, pouvant être appréhendés comme des espaces mésocritiques. En mobilisant particulièrement les concepts de cadre et de cadrage, l'article interroge la manière dont les acteurs et actrices construisent collectivement la futurité. À travers une étude longitudinale (2008–2024) centrée sur le cas lyonnais, il montre que ces cadrages, tantôt cohérents, tantôt ambivalents, influencent la capacité de l'espace à se structurer et à transformer les pratiques. L'enjeu central réside dans le maintien de leur alternativité, constamment menacée par des dynamiques d'hybridation ou d'isomorphisme avec le modèle conventionnel. |

| Abstract: | The interlinkages between climate change and socioeconomic inequality are increasingly acknowledged, yet analytical frameworks and empirical tools that jointly address these dimensions remain limited. This paper contributes to these discussions by distilling the key channels through which climate change and inequality mutually reinforce one another and by identifying a set of indicators to measure these linkages and inform policies in different country contexts. |

| Abstract: | We study the relationship between public policy and corporate profitability in the context of climate change. We use panel regressions on a sample of 25 S&P500 fossil fuel companies from 2004 to 2018. We show that public attention to climate issues can have a significant impact on financial performance of firms. Indeed, we observe that climate regulatory uncertainty, as well as the stringency of public environmental policies, do not have a significant impact on the ex-post profitability of the fossil fuel companies in our sample, except when public attention to climate issues intensifies. |

| Abstract: | Escalating climate-related catastrophe losses are placing increasing strain on private insurance markets, raising concerns about the long-term insurability of natural hazards. This paper describes the evolving roles of private and public institutions in sustaining catastrophe risk transfer. We first examine private catastrophe risk transfer mechanisms and discuss how rising loss volatility and modeling uncertainty are constraining private market capacity. We then compare catastrophe insurance arrangements across 13 countries and US states, identifying four institutional regimes that differ in the extent and form of government involvement. Across these regimes, we analyze the economic logic underlying public sector involvement, with particular emphasis on its roles in expanding risk pooling and enabling cross-subsidization to sustain insurance markets. We also discuss complementary policies that improve data availability and promote risk mitigation. Our analysis provides a framework for understanding how public-private arrangements can sustain insurance availability and enhance financial resilience under worsening climate risk. |

| Abstract: | Tomato prices in Kolar market exhibit high volatility alongside recurring seasonal patterns, but the consistency of these patterns across years remains unclear. This study analysed weekly tomato prices and arrivals from 2010-2024 to quantify inter-annual variability using descriptive statistics, seasonal indices, and Dynamic Time Warping (DTW). Descriptive analysis confirmed extreme fluctuations (CV = 77% for prices, 102% for arrivals) with positive skewness and heavy tails, indicating frequent extreme events. Seasonal indices revealed recurring intra-year cycles, but year-to-year alignment varied substantially. DTW analysis for 2021-2024 quantified pattern similarity, showing that 2022-2023 had the highest alignment (DTW distance: 23, 258) despite extreme price spikes, whereas 2021-2022 exhibited the weakest alignment (distance: 39, 049), reflecting structural shifts in market dynamics. Path length metrics indicated minimal temporal warping in 2022-2023 (71 points) versus extensive alignment in 2021-2022 (83 points). These results demonstrate that while seasonal patterns recur, their temporal consistency is not fixed, highlighting the need for forecasting models that adapt to both magnitude volatility and temporal shifts. The study also illustrates the utility of DTW for agricultural price analysis and the limitations of relying solely on fixed seasonal patterns in volatile commodity markets. |

| Abstract: | This study is the first attempt to examine the extent to which the Big Five personality traits and cognitive skills (Raven scores, numeracy, and literacy scores) are correlated with debt negotiation and debt management in a Global South country; and how social identity – in particular caste and gender – channels the effect of cognition on debt outcomes. Using a panel dataset built from an original household survey (called NEEMSIS) conducted in 2016–2017 and 2020–2021 in rural Tamil Nadu, India, and employing multivariate correlation probit analysis with lagged variables, we find the following. Firstly, conscientiousness is an advantage in the negotiation and management of debt, particularly for non-Dalit women, suggesting that, in a rural patriarchal context, women leverage personality traits to overcome the constraints of social identity. Secondly, emotional stability is a disadvantage in both debt negotiation and management. Thirdly, the role of cognition and in particular the Raven score is ambiguous. |
