| Abstract: | Weather variability disrupts food grain production and agricultural sustainability. While existing literature highlights the stationary relationship between weather variables and agricultural outcomes, it often overlooks their bearing on land use changes. This study investigates the dynamic effects of weather variations on crop yields, farmland use and intensity in Odisha, India, using district-level data from 2001-18. By employing a panel autoregressive distributive lag model, we assess long-and short-term relationships between weather parameters and agricultural yields. Results reveal a negative yield elasticity to rainfall deviation, ranging from-0.16 for wheat to-0.48 for green gram in the long term. In the short term, however, elasticity is positive for some pulses (green gram, urad) and oilseeds (groundnuts). Rainfall deviation and maximum temperature adversely affect the rate and intensity of farmland use but enhance crop diversification in both the short and long term. |

| Abstract: | Climate change poses significant threats to Indian agriculture, markedly through its impact on crop yields. While most existing research focuses on climate-sensitive crops like rice, relatively climate-resilient cereals such as sorghum, maize and finger and pearl millets have received less attention. This study uses district-level data from four southern states over 26 years to conduct a moment-based analysis of the effects of various climatic and non-climatic factors on these crop yields. The research offers nuanced insights into how different weather patterns influence crop yields, yield variability (risk) and downside yield risks. The study disaggregates climate variables into seasonal effects, showing that winter maximum temperatures positively affect the yields of maize and sorghum but negatively impact rice. In contrast, summer maximum temperatures generally reduce yields across all crops except finger millet, which thrives due to its heat tolerance. Monsoon rainfall boosts the yields of pearl millet, although excessive rainfall during the monsoon season increases downside risks for maize and rice. Evapotranspiration shows mixed effects, while wind speed tends to negatively affect yields, especially during the summer and monsoon seasons. Additionally, the study finds that excessive irrigation can harm rainfed crops like maize and pearl millet, while technological advancements such as HYV seeds and fertilisers positively impact yields. These findings underscore the urgent need to promote climate-resilient crop varieties, restructure irrigation subsidies and provide targeted support to smallholder farmers to enhance food security in the face of increasingly erratic seasonal conditions. |

| Abstract: | Ethiopia has significant untapped irrigation potential, but progress in the sector remains constrained by sole reliance on public investment, governance challenges, and limited private sector participation. Recognizing these issues, the Government of Ethiopia has prioritized Public-Private Partnerships (PPPs) as a strategy to accelerate irrigation development, enhance agricultural productivity, and improve rural livelihoods. In collaboration with the Ministry of Agriculture and the Ministry of Irrigation and Lowlands, the International Water Management Institute (IWMI) conducted a comprehensive needs assessment to identify stakeholder priorities and guide the development of viable PPP business models for smallholder irrigation. This study, part of the CGIAR Diversification in East and Southern Africa (UU) initiative and Scaling for Impact Science Program, is designed to inform the national guidelines for PPP implementation in Ethiopia’s smallholder irrigation sector. The report presents insights from extensive stakeholder mapping, key informant interviews, and focus group discussions across multiple regions in Ethiopia. Findings reveal strong interest among farmers and private sector actors to engage in irrigation PPPs, provided clear policies, incentives, and institutional support systems are in place. However, challenges remain, including fragmented governance, inadequate infrastructure, limited access to credit, weak market integration, and capacity gaps among farmers and Irrigation Water User Associations (IWUAs). Key recommendations emphasize the need for clear legal frameworks, strengthened institutional capacity, incentives to attract private investment, value chain integration, and targeted capacity building for farmers and IWUAs. The study also highlights the importance of inclusive approaches that engage women and youth, and the need for effective monitoring and regulation to ensure PPPs contribute to social equity and environmental sustainability. By addressing these systemic challenges, PPPs can become a transformative tool for Ethiopia’s smallholder irrigation development, supporting food security, climate resilience, and economic growth. This report serves as a critical reference for policymakers, practitioners, and development partners working to foster sustainable and inclusive irrigation systems in Ethiopia and beyond. |

| Abstract: | Agricultural sector has been identified as the engine room for economic transformation for most African countries, which plays an important role in their economic transformation process via huge revenue generation, employment creation, source of foreign exchange and food supply to mentioned a few. The impact of agriculture sector on Africa countries economic growth has become a significant area of study. The main focus of this paper is to investigate the impact, explore the possibilities and highlight the teething challenges that have masked the significant roles of agricultural sector in the transformation process of the Nigeria’s economy from transforming from a developing one to advanced nation. This paper span from the period 1970 to 2010 by using annual times series data. The Ordinary Least Square (OLS) estimation method was adopted to examine the impact of agricultural sector in the economic growth of Nigeria. The variables employed include: Gross Domestic Product (GDP), output of agricultural sector, share of agriculture in the GDP, index of agricultural production, and ratio of agricultural output to GDP. The results of the analyses showed that the Nigeria agricultural sector contributes immensely to the economic growth of Nigeria but the over-dependence on the oil sector has over shadowed the potentials of the sector. In conclusion, some of the recommendations made in the study are that: the Nigerian agricultural policy needs to be evolved; there is need for national re-orientation towards agriculture or farming, the activities of agriculture financing, institutions in providing finance and credit for rural farmers, should be supplemented with the provision of road networks, rail system and warehouses, in order to further encourage farmers to increase their production etc. |

| Abstract: | Livestock waste poses significant environmental and public health challenges in low- and middle-income countries (LMICs), particularly through water pollution and the spread of infectious diseases. Nutrient-rich runoff from this waste contributes to eutrophication, while pathogens such as Escherichia coli and Salmonella contaminate surface waters, posing serious risks to human and animal health. Yet, this waste stream also presents opportunities for circular bioeconomy solutions. When converted into biogas, organic fertilizer, or aquaculture feed, livestock waste can help mitigate environmental harm, generate energy, enhance soil health, and support rural livelihoods. This report synthesizes findings from 135 global cases and further presents an in-depth analysis of 26 livestock waste recovery initiatives to highlight diverse models and regional strategies. The available data show that in Latin America and Sub-Saharan Africa, biodigestion is primarily used for household or commercial energy and revenue generation. South and Southeast Asian countries, meanwhile, focus on producing compost, aquaculture feed, and vermicompost. Government support, including subsidies, incentives, and technical assistance, often underpins these efforts, sometimes in collaboration with the private sector. Three broad business models emerge: (i) energy and biofertilizer recovery, (ii) soil nutrient recovery, and (iii) food nutrient recovery for aquaculture. Government-led community initiatives tend to exhibit higher economic feasibility, while private-sector models tend to scale better commercially. With average payback periods of five to six years and cost-benefit ratios ranging from 1 to 2, these models offer scalable solutions—when backed by enabling policies, institutional coordination, and localized feasibility assessments—to promote sustainable rural development and address critical environmental risks. |

| Abstract: | The analysis of the malagasy “land rebound effect, ” conducted using an ordinary least squares (OLS) linear regression model and panel data of 27 countries on World Bank time series data from 1990 to 2022, quantitatively demonstrates the relationship between agricultural value added and the expansion of cultivated land areas. The findings suggest three priority interventions: contextual adaptation of technologies through participatory approaches, strengthening land tenure security via formal certification tools, and building the capacities of local producers including training, financing, and economic diversification. However, there are methodological limitations due to the lack of detailed data on land dynamics and institutional constraints within rural communities, calling for complementary field studies to ground the econometric analysis in territorial realities. |

| Abstract: | This paper investigates the preferences of smallholder farmers residing in the agricultural frontier of the Colombia Amazon's Forest, specifically in the department of Guaviare, regarding interventions aimed at promoting the adoption of sustainable land-use systems. We focus on the transition from extensive livestock systems to sustainable livestock systems and agroforestry systems. The adoption of silvopastoral systems presents a significant opportunity for sustainable development, offering land-saving advantages that can be leveraged by programs to encourage other sustainable value chains, such as timber in agroforestry systems. Through a discrete choice experiment, we examine farmer preferences concerning land allocation, cash bonuses for permanence, and technical assistance. Additionally, we assess how socioeconomic factors influence farmers' decision-making in participating in such programs. Our findings indicate that while farmers exhibit a preference for allocating land to silvopastoral systems over agroforestry, they also show considerable interest in interventions involving a small proportion of timber in agroforestry systems. Furthermore, our analysis reveals that permanence bonuses tied to individual effort can enhance participation, while collective goals may hinder it. |

| Abstract: | Water management presents significant challenges in Africa due to problems that link food security, poverty, ecosystem degradation, population growth, urbanization, and climate change, each influencing the other. Central to this is the challenge of irrigation development, including inadequate infrastructure, poor operational and maintenance practices, and limited access to innovative solutions in public sector-led schemes. The need for large-scale irrigation infrastructure in Africa persists and is likely to increase in the coming decades. In most cases, the actual size of state-led irrigable land realized has been significantly smaller than planned, resulting in smaller plot allocations than theoretically thought possible. This has negatively impacted poverty alleviation and food security efforts, where farmer-led irrigation development (FLID) is only beginning to emerge. Significant areas with irrigation infrastructure are only discontinuously cultivated in most places, while others are permanently abandoned. Many irrigation schemes continue to operate below capacity due to inadequate operation and maintenance frameworks, misaligned institutional mandates, and limited farmer engagement. In transboundary cases, documented evidence suggests investing in a win-win regional policy approach to foster cooperation and integration at the national scale across economic communities. If implemented successfully, this effort will increase and enhance opportunities for developing cascaded irrigation systems and realizing irrigation potential at multiple scales—across formal and informal irrigation subsectors. Addressing Africa’s irrigation development and water management crises requires an integrated approach that combines technological innovation, robust policy reforms, and farmer-led or community-driven water stewardship, with a focus on inclusion to build resilience against the impacts of climate variability. |

| Abstract: | India's agriculture and allied sector grew at an average annual rate of 4.6 percent in gross value added (GVA) terms from Financial Year 2010-11 (FY 11) to FY23. Interestingly, during this period, fisheries and aquaculture witnessed a much faster growth of 8.2 percent while cereals increased by just 3 percent annually in terms of gross value of output (GVO). The rapid growth in inland fisheries and the increasing global demand for Indian fisheries position this sector as a key contributor to enhancing farmers’ incomes. This policy brief examines the key drivers of inland fisheries expansion in India over the last four decades and assesses its potential to strengthen rural livelihoods by diversifying income sources. Rising incomes, technological advances in seed production, strategic government support through initiatives like Pradhan Mantri Matsya Sampada Yojana (PMMSY), and export growth, particularly of Litopenaeus Vannamei (L. Vannamei) shrimps, have driven the growth of India's fisheries sector, showing a significant positive impact on GVA. It also highlights some of the challenges this sector faces, especially in terms of environmental issues, access to finance, and risk coverage. But overall, the research evidence shows significantly higher profitability of aquaculture—especially shrimp farming—compared to crop agriculture. Thus, this sector has a potential to play a transformative role in promoting inclusive and sustainable rural growth in India. |

| Abstract: | The Solar Irrigation for Agricultural Resilience (SoLAR) program, led by the International Water Management Institute (IWMI) with support from the Swiss Agency for Development and Cooperation (SDC), has advanced climate-resilient, gender-equitable, and socially inclusive farming livelihoods in Bangladesh, India, Nepal, and Pakistan since 2019. By promoting solar irrigation pumps (SIPs), the initiative supports clean energy transitions in agriculture, reducing reliance on diesel and helping farmers adapt to rainfall variability without significantly increasing groundwater use. Key learnings from the program emphasize four pillars for sustainable transitions: robust evidence for policy, diverse and scalable business models, inclusive policy advocacy, and strengthened gender and social inclusion through community engagement and capacity building. Beyond South Asia, SoLAR is fostering South-South collaboration to extend these lessons to East Africa, contributing to global pathways for sustainable and inclusive agricultural resilience. |

| Abstract: | Climate change impacts farms’ risk profiles and farms’ expected returns; yet farms seem to be reluctant to invest into adaption measures. Previous literature suggests that delayed adaptation is due to the real option nature of such investments: irreversibility, flexibility in timing, and (economic) uncertainty. We test these theoretical considerations by empirically examining irrigation uptake among Danish farms. We consider production inefficiency, market and weather risk, and experienced climate extremes as determinants of irrigation adoption behavior. Our analysis uses a panel of 1, 104 farm-level observations from the FADN for 2007–2020 combined with weather, climate and price data. We model farms’ persistent inefficiency using a 4-component stochastic frontier; a panel logit quantifying the effects of inefficiency, climate extremes, and price and weather volatility on adoption. Our results align with predictions from real options theory: higher market uncertainty lowers adoption rates, whereas exposure to extreme drought increases the probability of investing. Results also suggest that crop-market signals matter, suggested by higher adoption rates under greater potato price volatility, indicating anticipatory investment when upside price risk is salient. We find that higher farm-level efficiency is associated with a lower propensity to invest, pointing either to substitution toward other risk-management or yield-enhancing strategies, or to less binding water constraints on already efficient farms. Our current results therefore suggest that additional policy initiatives may be required to foster adaptation levels adequate for expected climate change development. |

| Abstract: | This baseline study draws on Resilient Nature-Based Water Solutions (RNBWS) pilot interventions undertaken by the Al Murunah project in the upper catchment of Wadi Al-Fari’a, specifically in the communities of Ras Al-Fari’a, Wadi Al-Fari’a, and the Fari’a Refugee Camp in the Occupied Palestinian Territories (OPT). It provides a detailed account of the 2023 analysis of the biophysical, socio-economic, agricultural, and policy contexts shaping the technical, social, and market design of the pilot, as well as broader project activities, including capacity building, training, and policy engagement. The study presents a synthesis of strengths, weaknesses, opportunities, and threats (SWOT) related to RNBWS in Wadi Al-Fari’a, and outlines strategies for the planned pilot, alongside general recommendations for advancing RNBWS and the integrated development of agricultural and water resources in the West Bank. By linking local insights to policy priorities, Al Murunah aims to forge a strategic pathway for implementing RNBWS, strengthening agricultural resilience, and fostering inclusive, sustainable socio-economic growth. The pilot and its recommendations seek to position the project’s approach as a scalable model for sustainable development across the OPT, contributing to the Palestinian Authority’s vision for water security, food production, and effective climate change adaptation. |

| Abstract: | The main challenge facing the agricultural landscapes of the Mediterranean and North African regions is not only climate change, but also the degradation of ecosystem services and the loss of biodiversity. The aim of this study is to investigate the adoption of agroecology as a solution to these problems by farmers in a case study in Algeria. To begin with, we determine the farmers' position in the agricultural system and their relationship with other components of the system using Ostrom's Social-Ecological System framework (SESF) (2009). In this step, we also identify the factors that affect farmers' decision-making processes. Subsequently, we enhance an existing bio-economic model with the outcomes of the previous step in order to assess farmer's adoption to agroecology. Finally, using bio-economic model we will determine policy scenarios to accelerate of agroecological transition. |

| Abstract: | The Middle East and North Africa (MENA) Region is one of the most water-scarce in the world, with agriculture accounting for 65% of total water use. This challenge is compounded by land degradation and the intensifying impacts of climate change. In response, the Al Murunah project—meaning “flexibility” in Arabic—was launched to enhance water security through resilient nature-based water solutions (RNBWS) in Egypt, Jordan, Lebanon, and the Occupied Palestinian Territories (OPT). Al Murunah is a five-year initiative funded by the UK’s Foreign, Commonwealth and Development Office (FCDO), led by the International Water Management Institute (IWMI) in partnership with the International Union for the Conservation of Nature (IUCN). The project promotes the integration of nature-based solutions for water (NBSW) with agricultural water management (AWM) to address water scarcity and build resilience across the region. This report, titled Development of a Capability and Skillset Framework for the Implementation of Resilient Nature-Based Water Solutions (RNBWS) in the MENA Region, defines the capacities—knowledge, skills, and capabilities—required to implement RNBWS in the four project countries. These capacities form the foundation of the RNBWS Capacity Framework, a key output designed to guide implementation, support pilot initiatives, inform upscaling efforts, and serve as a tool for institutional analysis. The report is structured around three core components: • Development of stakeholder personas representing typical RNBWS users; • Identification of the capacities required by these personas for successful implementation; • Development of an RNBWS Training and Certification Framework to guide the review of training and certification processes for the identified capacities of personas in the project countries and through remote online platforms. |

| Abstract: | This policy brief assesses the potential implications of reciprocal tariffs on India's agricultural exports, analysing key trade trends, tariff disparities, and non-tariff barriers. While India has historically relied on protective tariffs to safeguard domestic farmers, retaliatory measures from the U.S. could reduce market access for Indian agricultural products. The challenge for India is to balance domestic agricultural interests while ensuring that trade relations with the US remain stable. Overall, it seems that in case of reciprocal tariffs in agriculture, India’s agri-exports to US may come down and its imports from US will go up, thereby reducing or even wiping out the agri-trade surplus. |

| Abstract: | Farmers increasingly use videos and other digital tools to access and share farming information. However, women in agriculture have commonly been excluded from influencing and accessing these digital tools. Rigorous evaluations have found that including women farmers in the creation and screening of farming videos can benefit women through improved productivity and decision-making power. But what is needed for extension workers to make these videos accessible to women farmers outside of carefully managed pilots? We implemented a randomized controlled trial testing how the gender of farmers featured in wheat farming advisory videos influenced how much, and with whom, 294 extension workers shared these videos in rural Bihar. We interpreted results through twenty follow-up interviews and the ‘Mechanisms and Conditions’ framework based in affordance theory. We found the extent to which extension workers shared videos with women farmers hinged on extension workers' perceptions, material resources, and cultural contexts, rather than the gender of farmers featured in videos. From a theoretical perspective, this core finding suggests the 'Mechanisms and Conditions' framework requires modification to account for material resource access when explaining technology use. From a practical perspective, the core finding prompts practitioners to ask ‘how might extension systems circulating digital tools be more inclusive?’, not just ‘how might we adapt digital tools to be more inclusive?’. This systems-level approach to empowering women in agricultural innovation systems could involve supporting inclusive person-to-person extension networks, and avoiding dependence on smartphone-based extension systems, like YouTube and chatbots. |

| Abstract: | The 2022 Ukraine conflict has contributed to a major spike in international commodity prices. In this study, we conduct a top-down, macro-micro simulation analysis by combining Computable General Equilibrium simulations with data from the 2018-19 Pakistan Household Integrated Economic Survey to analyze the impact of global price shock to four major commodities, namely wheat, vegetable oil, petroleum, and fertilizers. We come up with evidence for a significant, non-negligible negative impact of the price shock, both at the aggregate and the household level: Real GDP shrinks and real household consumption and income decrease. The drop in consumption and income is more visible among farm households, with the two falling by 5% and 3.48% respectively. The consumption and income of the above-median income households fall more steeply, and income inequality decreases. The USD3.2 headcount poverty rate at the 2018 purchasing power parity increases by 1.15%. Urban households show the worst decline in food security, both in incidence and intensity. The role of petrol prices in driving poverty among rural farm households and that of food stuff (wheat and vegetable oil prices) in aggravating urban food security is particularly evident. These findings highlight the poverty and food security-worsening dimension of the Russo-Ukrainian conflict. |

| Abstract: | This report presents in summary form, information concerning the recent levels of agricultural production, expected short-run changes in production and desirable long-time adjustments for the major areas of the Southern Great Plains. This material has been developed over the past several months by the Bureau of Agricultural Economics, with informal cooperation by workers in State Colleges and Experiment Stations and regional personnel of the various action agencies. Consideration has been given to the recommendations for production adjustment made by State and county agricultural planning committees. An attempt is made in this report to analyze the agricultural adjustments now under way and in prospect in the light of the needs of the war emergency period and with respect to desirable long-run- adjustments. Two sets of adjustments are considered: (1) probable adjustments during the defense period and a discussion of the desirability of these changes; and (2) desirable long-time adjustments. |

| Abstract: | This paper synthesizes evidence on climate change impacts specific to U.S. populations. We develop an apples-to-apples comparison of econometric studies that empirically estimate the relationship between climate change and gross domestic product (GDP). We demonstrate that with harmonized probabilistic socioeconomic and climate inputs these papers project a narrower and lower range of 2100 GDP losses than what is reported across the published studies, yet the implied U.S.-specific social cost of greenhouse gases (SC-GHG) is still greater than the market-based damage estimates in current enumerative models. We then integrate evidence on nonmarket damages with the GDP impacts and recover a jointly-estimated SC-GHG. Our findings highlight the need for more research on both market and nonmarket climate impacts, including interaction and international spillover impacts. Further investigation of how results of macroeconomic and enumerative approaches can be integrated would enhance the usefulness of both strands of literature to climate policy analysis going forward. |

| Abstract: | Anticipated growth in renewable energy will substantially curtail the US energy sector’s greenhouse gas emissions but has implications for land-based sectors of the economy. US climate policies and energy markets now provide especially strong incentives for expanding solar photovoltaic (PV) capacity. As a result, conversion of agricultural and forested lands to utility-scale solar facilities has accelerated over the past decade. Energy projections indicate a rapid expansion in the rate of solar development and land use changes, especially where high electricity demand coincides with access to transmission infrastructure. This implies a concentration of effects on ecosystem services. Rising public alarm regarding solar siting, initially focused on agricultural land, portends challenges for land-based sectors and the clean energy transition.This report provides a rapid assessment of potential conversions of forestland to solar facilities. We evaluate the current land use footprint of solar facilities in the United States and land use conversions to support solar production. We examine the policy structures that currently organize the development of solar capacity and evaluate the potential for future land use change. And we explore the associated economic and ecological implications of changes, social concerns, and emerging policy responses.Our analysis starts with a survey of the literature on solar land use, compilation of available data, and development of a simple projection model. Because the published literature on forest conversion is sparse, we also sought out experts in state forestry organizations, the land trust community, and the energy sector, and we interviewed them about the scope and scale of forest conversion to solar farms, as well as ways in which stakeholders may be affected. We specifically sought insights into patterns of conversion, data sources, and societal issues (e.g., equity, loss of wildlife habitat). Interviewees also weighed in on emerging policies aimed at mitigating the consequences of solar conversions.As is the case for land development more broadly, converting forests and native grasslands to solar facilities alters the provision of ecosystem services, ranging from commodities such as timber and carbon storage to public goods related to water quality, species’ habitat, recreation, and aesthetics. Consequences include those that accrue to deforestation in general but also issues specific to solar operations. The spatial concentration of solar development implies an uneven distribution of effects. As well as balancing the provision of renewable energy with loss of valuable ecosystem services, best practices for the design of new facilities need to address local communities’ concerns. At all levels of government, policy is still adapting to the challenges associated with solar-driven land use change. |

| Abstract: | U.S. fertilizer production and consumption—crucial for the productivity of U.S. agriculture—take place within a global fertilizer market. The fertilizer price increases of 2021–22, driven by a set of national and global market events, pushed U.S. fertilizer costs per acre for corn and wheat in 2022 to more than double their levels in 2020. This study analyzes U.S. fertilizer production, consumption, and trade from 2006 (the last full year preceding the Great Recession) to 2023. Relative to 2006, U.S. fertilizer consumption and production have declined. Over the study period, U.S. nitrogen fertilizer consumption remained higher than phosphate and potash fertilizer consumption combined. Whereas phosphate fertilizer was once the main fertilizer produced in the United States, nitrogen fertilizer now makes up the largest share of production, while potash fertilizer made up 2 percent or less of total U.S. fertilizer production throughout the period. While global production and trade in fertilizer have increased, the U.S. share of world fertilizer production, imports, and exports have each declined by 25 percent or more since 2006. |

| Abstract: | Fish consumers are often challenged by tradeoffs between nutritional benefits and contaminant risks, which increase due to environmental pollution. Health campaigns and labeling initiatives can guide decision-making by providing information both on contaminant risk and nutritional value of a product, but it is not well understood how consumers react to such complex dual labels. We use data from a stated choice experiment in Kenya’s Lake Victoria region to study how consumers respond to dual labels on fish products, and how their responses to each label interact. We focus on the tradeoff between polyunsaturated fatty acids and contamination with microcystin, a toxin that accumulates in fish during harmful algae blooms. Our findings suggest that, faced with a dual information policy, consumers react rationally to dual health attribute labeling, and that nutrient labels and contaminant warnings can function concurrently, indeed even be mutually reinforcing, but pose a risk of inadvertently concentrating unhealthful consumption in less responsive subpopulations. |

| Abstract: | The global food system provides nourishment to most of the world’s eight billion people, generates trillions of dollars of goods and services, and employs more than one billion people. On the other hand, it generates substantial dietary health costs and environmental harms. Policymakers are asking about the overall contribution of the global food system to social welfare and how much larger it might be on a sustainable path. This paper describes our efforts to answer these questions. We couple multiple domain-specific models into a large-scale integrated assessment modelling framework capable of quantifying the outcomes of different food-system scenarios for incomes, health and the environment up to 2050, at a highly disaggregated level. We take these multi-dimensional outcomes and value them using a system of nested utility functions, building on recent work in environmental economics. We find that, relative to current trends, the bundle of measures in a Food System Transformation scenario would provide a large boost to global social welfare equivalent to increasing global GDP by about 7%. Changes in income, environment and health all contribute positively. Measures to change diets are particularly beneficial, although a caveat is that our welfare estimates exclude possible consumer disutility from dietary changes. The results are robust to changes in key utility/damage parameters. |

| Abstract: | Agricultural residues represent a vast, underutilized resource for renewable energy. This study combines empirical analysis from 179 countries with a case study of a pelletization facility to evaluate the global potential of agricultural pelletization for fossil fuel replacement. The findings estimate a technical availability of 1.44 billion tons of crop residues suitable for pellet production, translating to a 4.5% potential displacement of global fossil fuel energy use, equating to 22 million TJ and equivalent to 917 million tons of coal annually. The economically optimized scenario projects annual savings of $163 billion and a reduction of 1.35 billion tons of CO2 equivalent in emissions. Utilizing the custom-developed CLASP-P and RECOP models, the study further demonstrates that agricultural pellets can achieve competitive pricing against conventional fossil fuels in many markets. Despite logistical and policy challenges, agricultural pelletization emerges as a scalable, market-driven pathway to support global decarbonization goals while fostering rural economic development. These results reinforce the need for targeted investment, technological advancement, and supportive policy to unlock the full potential of agricultural pellets in the renewable energy mix. |

| Abstract: | This paper examines the effects of daily temperature fluctuations on subnational economic growth in Thailand. Using annual gross provincial product (GPP) per capita data from 1982 to 2022 and high-resolution reanalysis weather data, I estimate fixed-effects panel regressions that isolate plausibly exogenous within-province year-to-year variation in temperature. The results indicate a statistically significant inverted-U relationship between temperature and annual growth in GPP per capita, with adverse effects concentrated in the agricultural sector. Industrial and service outputs appear insensitive to short-term weather variation. Distributed lag models suggest that temperature shocks have persistent effects on growth trajectories, particularly in lower-income provinces with higher average temperatures. I combine these estimates with climate projections under RCP4.5 and RCP8.5 emission scenarios to evaluate province-level economic impacts through 2090. Without adjustments for biases in climate projections or lagged temperature effects, climate change is projected to reduce per capita output for 63-86% of Thai population, with median GDP per capita impacts ranging from -4% to +56% for RCP4.5 and from -52% to -15% for RCP8.5. When correcting for projected warming biases - but omitting lagged dynamics - median losses increase to 57-63% (RCP4.5) and 80-86% (RCP8.5). Accounting for delayed temperature effects further raises the upper-bound estimates to near-total loss. These results highlight the importance of accounting for model uncertainty and temperature dynamics in subnational climate impact assessments. All projections should be interpreted with appropriate caution. |

| Abstract: | The first semi-annual Stakeholder Forum of 2025 of the Sub-sector Working Group on Irrigation (SSWGIR) was held in Vientiane Capital, Lao People’s Democratic Republic (Lao PDR). It was organized by the Department of Irrigation (DOI) under the Ministry of Agriculture and Environment and supported by the Asian Development Bank (ADB) together with the International Water Management Institute (IWMI). The event was attended by 80 participants from government, academia, development organizations, farmer groups, and enterprises from the banking, insurance, hydropower, and mining sectors. The forum serves as a strategic coordination platform that offers high level support to the MAF’s Sectoral Working Group on Agriculture and Rural Development (SWG-ARD) and regular coordination among key stakeholders for more effective resource utilization and synergy enhancements for different irrigation development agenda topics or issues. The specific objectives of this particular event are to facilitate discussions on the opportunities and potential of harnessing geographic information systems (GIS) for irrigation management and development in the Lao PDR and to disseminate the new Irrigation Development Strategic Plan from 2026-2030 and Vision to 2040. The event also offered useful thoughts for DOI’s GISbased database establishment plan by reflecting on lessons learnt from other sectors. |

| Abstract: | This review synthesises applications of behavioural science approaches to farmer decision making and risk management. First, we identify key behavioural science concepts that have been found to influence the ways in which people make decisions, with illustration from the agricultural sector. These concepts include dispositional factors (e.g. risk preferences, loss and ambiguity aversion, time discounting), social factors (e.g. social norms), and cognitive factors (e.g. biases, heuristics, framing effects). Knowing how these various concepts influence attitudes towards risk helps to (a) better understand why people make decisions the way they do, and (b) design more effective risk management strategies and decision support tools. We present four behavioural science frameworks that can be used as a reference when designing behavioural interventions: the MINDSPACE framework, the EAST framework, the Behavioural Change Wheel model, and the Theory of Planned Behaviour. Key messages from these frameworks are the importance of making the desired option easy, social norms and the influence of peers, making information salient to the individual, and the role that emotions play in our decision process. The RiskWi$e project offers a unique opportunity to apply behavioural science knowledge in research design and extension to help agricultural risk management. |

| Abstract: | Consumers of products from food animals in general have a positive attitude toward the animal welfare attribute. However, animal welfare has various dimensions (e.g. cage-free, grass-fed, pain management), and there is little research to inform if the animal welfare attribute and its dimensions are complements or substitutes. We address the gap in the literature with a choice experiment to elicit preferences for the animal welfare attribute and the pain management attribute from 704 beef steak and 1, 261 milk consumers in the United States. Using WTP-space mixed logit models, we find that (1) in isolation animal welfare and pain management each capture a positive and significant WTP, and (2) in combination animal welfare and pain management are complementary and raise total WTP. Additionally, we find certification of the pain management attribute by private or public institutions is of importance to the magnitude of the WTP. |

| Abstract: | This paper presents a practitioner-led case study of Nông Sản Bán Buôn, a small agricultural e-commerce platform in Vietnam that aimed to connect rural producers to international markets. Unlike most research on digital trade which focuses on large platforms or macroeconomic policy, this study examines the practical barriers facing small, mission-driven ventures operating under resource constraints. Drawing on firsthand experience and qualitative documentation from 2017 to 2024, the paper identifies six core challenges: digital visibility, buyer trust, regulatory compliance, logistics infrastructure, access to capital, and pandemic-induced market shocks. The findings illustrate that technical innovation alone is insufficient for sustainability in emerging market contexts. Long-term success in agri-tech requires trust-building, inclusive infrastructure, and ecosystem-level coordination. This study contributes grounded insights to the literature on agricultural digital transformation and highlights policy directions to support small platforms in the Global South. |

| Abstract: | Madagascar, highly vulnerable to climate change, faces a significant climate finance deficit, securing only USD 385 million in 2022 against the USD 13.4 billion needed by 2030, as outlined in its Second Nationally Determined Contribution (NDC2). This study examines the barriers limiting Madagascar’s access to global climate finance, including weak institutional and technical capacities, a global bias favoring mitigation over adaptation, and heavy reliance on multilateral donors like the World Bank, which contributed 55\% of 2022 funding. Analysis of financial flows from 2015–2022 reveals volatile funding patterns, with peaks driven by large-scale projects and troughs reflecting institutional constraints. The energy sector dominates allocations, marginalizing critical adaptation needs in agriculture and water management. To bridge this gap, the paper proposes strengthening institutional capacity through centralized coordination, advocating for equitable global finance at forums like COP, and scaling innovative mechanisms such as local-currency green bonds and partnerships with PROGREEN and PROBLUE. Enhanced regulatory frameworks and transparency are critical to attract private investment and ensure equitable resource distribution. These systemic reforms, combining domestic action and international cooperation, are essential for Madagascar to achieve resilient, sustainable development amidst escalating climate risks. |

| Abstract: | Supplemental Nutrition Assistance Program (SNAP) aims to improve food security of low-income households in the U.S. A new, continuous food security measure called the Probability of Food Security (PFS), which proxies for the official food security measure but is implementable on longer periods, enables the study of SNAP's effects on the intensive margin. Using variations in state-level SNAP administrative policies as an instrument for individual SNAP participation, I find that SNAP does not have significant effects on estimated food security on average, both on the entire population and low-income population whom I defined as income is below 130\% of poverty line at least once during the study period. I find SNAP has stronger positive effects on those whose estimated food security status is in the middle of the distribution, but has no significant effects in the tails of the distribution. |

| Abstract: | On March 1, 2025, President Trump issued an executive order (EO 14225) directing the Secretaries of Agriculture and the Interior to develop plans to increase timber production on federal lands. The order was motivated by two stated priorities: expanding the timber supply and addressing rising wildfire risks. The US Forest Service has responded with a goal of increasing timber offered for sale by 25 percent over the next four to five years. This report puts the Trump administration’s actions into context by reviewing the history of harvest from federal lands and evaluating current forest inventories and treatment needs. It asks: What would be the effect on wildfire risk if federal land management agencies increased harvests by 25 percent? Opportunities for harvests that successfully mitigate risk may be limited by the absence of active timber markets, the availability of a qualified workforce, and the economics of fuel removals. While selective harvesting can play a role in hazard reduction, effects on risk depend on how and where harvests are implemented. Market realities and declining federal capacity to implement nuanced, site-specific forest treatments present real constraints. Moreover, the national significance of expanded federal harvests is limited; federal lands have long accounted for a small share of total US timber production, and most timber now comes from private lands, particularly in the South. Whether agencies can achieve both increased timber supply and meaningful reductions in wildfire risk will depend on how strongly the latter goal is prioritized in the design of timber sales. |

| Abstract: | We analyze the potential economic impacts in Argentina of the European Union Deforestation Regulation (EUDR), which as of January 2026 will prohibit the export to the European Union of certain raw materials and related products if they involve the use of deforested land. We estimate that the EUDR would cover around 6 billion US dollars in exported value, but only 2.84% is not compliant with the EUDR, with soy and cattle being the most affected production chains. We use a dynamic computable general equilibrium model to simulate the impact of the EUDR on the Argentine economy. If the non-compliant production cannot enter the EU market because of the EUDR, the results of the simulations suggest that the potential macroeconomic impacts are limited: GDP would be reduced by an average of 0.14% with respect to the baseline scenario. However, the potential environmental impact is greater. Deforested hectares would be reduced by 2.45% and GHG emissions by 0.19%. Notwithstanding, EUDR due diligence costs may still prevent compliant production from entering the EU market, so the total impacts could be higher. |

| Abstract: | This paper examines the challenges and strategies of agricultural e-commerce platforms in enhancing digital visibility, with a focus on the case of Nông Sản Bán Buôn in Vietnam. Using a case study approach, the research highlights how early adoption of search engine optimization (SEO) enabled rapid growth, but also how structural vulnerabilities, shifting digital algorithms, and the impact of the COVID-19 pandemic disrupted platform stability. The findings show that small and medium-sized enterprises (SMEs) in agriculture face unique barriers to sustaining online presence, including limited resources, technological dependence, and competitive asymmetries compared to larger players. By situating these experiences within broader academic debates on digital marketing, platform economies, and rural development, the study contributes to understanding the systemic inequalities embedded in digital commerce. The paper concludes with practical recommendations for SMEs to diversify marketing strategies, balance SEO with multi-channel engagement, and strengthen resilience in rapidly changing digital environments. |
