The United States authorized unprecedented investments in agri-environmental programs in 2022, dedicating over $19 billion to soil and water conservation practices with climate mitigation and adaptation benefits. We examine historical funding patterns, new funding allocations, and evaluation approaches for these programs. Our analysis reveals four key findings: (1) Nearly 40% of prior conservation funding has supported climate-beneficial practices, with increasing shares reflecting growing producer demand; (2) Although enrollment of historically underserved producers (HUPs) has increased, variation across programs and higher contract non-completion rates among this group suggests enhanced pre- and post-enrollment support services could be valuable; (3) A shift toward partnership-style programs facilitate locally-tailored agreements and market linkages, potentially broadening producer participation while enabling more durable incentives for sustained practice adoption; (4) current evaluation approaches primarily focus on implementation metrics paired with biophysical modeling and could be strengthened through rigorous impact evaluation design. Promising techniques include conducting randomized experiments and integrating geospatial data with program records to assess the impacts on producer behavior as well as program outcomes over time and space. Such approaches can build evidence for strategic conservation finance and de-risk future investments for other types of financial services—accelerating transformation toward sustainable agri-food systems in the United States and beyond.

2022年,美国批准对农业环境项目进行前所未有的投资,投入190多亿美元用于具有减缓和适应气候变化效益的水土保持措施。我们研究了这些项目的历史资助模式、新的资金分配和评估方法。我们的分析揭示了四个主要发现:(1)近40%的先前保护资金支持了有利于气候的实践,这一比例的增加反映了生产者需求的增长;(2)虽然历史上服务不足的生产者(HUPs)的注册人数有所增加,但项目之间的差异和该群体较高的合同不完成率表明,加强注册前和注册后的支持服务可能是有价值的;(3)向伙伴式项目的转变促进了当地定制的协议和市场联系,潜在地扩大了生产者的参与,同时为持续采用实践提供了更持久的激励;(4)目前的评价方法主要侧重于与生物物理建模相结合的实施指标,可以通过严格的影响评价设计来加强。有前景的技术包括进行随机实验,将地理空间数据与项目记录相结合,以评估生产者行为和项目结果随时间和空间的影响。这些方法可以为其他类型金融服务的战略性保护融资和降低风险的未来投资提供证据,从而加速美国及其他地区向可持续农业食品系统的转型。

Role of International Price and Domestic Inflation in Triggering Export Restrictions on Food Commodities 国际价格和国内通货膨胀在触发粮食商品出口限制中的作用

This paper investigates the drivers of export restrictions on agricultural products based on an original dataset developed at IFPRI. We focus on four food price crises when export restrictions (bans, taxes, licenses, etc.) were applied: the 2007–2008 and 2010–2011 food price crises, the COVID-19 pandemic, and the 2022 crisis associated with the Russia–Ukraine war. Although the justifications for such trade policies have been discussed in the literature, the ability to forecast their implementation remains understudied. The probit model used in this study suggests that the inflation rate has a higher power to predict export restrictions than do international commodity prices. The probability of export restrictions increases more when price changes are measured from a reference level in the long term than in the short term. Among the covariates, agricultural land per capita, the commodity's share in total production, and weather conditions increase the chances of imposing export restrictions. Population density, share of agriculture in GDP, urbanization rate, and political economy indicators all have a negative influence on the likelihood of export controls.

本文基于IFPRI开发的原始数据集调查了农产品出口限制的驱动因素。我们重点研究了实施出口限制(禁令、税收、许可证等)的四次粮食价格危机:2007-2008年和2010-2011年粮食价格危机、2019冠状病毒病大流行以及2022年与俄乌战争相关的危机。虽然这些贸易政策的理由已在文献中讨论过,但预测其实施的能力仍未得到充分研究。本研究使用的probit模型表明,通货膨胀率对出口限制的预测能力高于国际商品价格。如果从长期的参考水平来衡量价格变化,那么出口限制的可能性会比从短期的参考水平来衡量更大。在协变量中,人均农业用地、商品在总产量中的份额和天气条件增加了实施出口限制的可能性。人口密度、农业占GDP的比重、城市化率和政治经济指标均对出口管制的可能性产生负向影响。

This study employs a quasi-natural experiment using 7 years (2010–2016) of enterprise tax data from China, leveraging staggered highway openings at the county level to construct a difference-in-differences (DID) model. The findings reveal that highway access significantly enhances the profitability of agricultural enterprises. Robustness tests confirm these results. Heterogeneity analysis reveals that highway access has a greater impact on firms producing perishable agricultural products (e.g., vegetables, fruits, livestock, and aquaculture) and those located farther from major markets. Mechanism analysis suggests that highway access enhances agricultural enterprise profitability by improving transportation efficiency, expanding market reach, and lowering operational costs. Further analysis reveals that highway access positively influences firm productivity. These findings offer valuable insights for policymakers seeking to enhance sustainable agricultural development globally.

本研究采用准自然实验方法,利用中国7年(2010-2016)的企业税数据,利用错开的县级公路建设,构建差异中差异(DID)模型。研究发现,高速公路可显著提高农业企业的盈利能力。稳健性测试证实了这些结果。异质性分析表明,高速公路通道对生产易腐农产品(如蔬菜、水果、牲畜和水产养殖)和远离主要市场的企业的影响更大。机理分析表明,高速公路可通过提高运输效率、扩大市场覆盖范围和降低经营成本来提高农业企业的盈利能力。进一步分析表明,高速公路通道对企业生产率有正向影响。这些发现为寻求加强全球可持续农业发展的政策制定者提供了有价值的见解。

Climate Resilient Development for Agriculture and Pathways for Gender Inclusivity 气候适应型农业发展和性别包容之路
IF 4.5 3区 经济学 Q1 AGRICULTURAL ECONOMICS & POLICY Pub Date : 2025-04-22 DOI: 10.1111/agec.70040

This study introduces a new concept and framework called Climate Resilient Development for Agriculture (CRDA) to serve as a roadmap for agricultural transformation in the face of climate change. It also explores how to address gender inequity in agriculture during this transformation process. Unlike Climate Resilient Agriculture (CRA), which focuses solely on adjusting farming practices to reduce greenhouse gas emissions and maintain agricultural production in the face of climate change, CRDA takes a more comprehensive approach by integrating a development perspective. Its goal is to leverage synergies among actions, programs, and policies to achieve climate change mitigation, adaptation, and sustainable development goals while also addressing climate change induced loss and damage in the agriculture sector. The CRDA framework outlines potential pathways leading to either high or low CRDA futures and emphasizes the importance of gender equity in its structure. Additionally, the study highlights the potential for actions under the CRDA framework to either exacerbate or mitigate gender disparities and proposes five key actions that can contribute to a gender-inclusive and climate-resilient future for the agriculture sector.

本研究引入了一个名为气候适应型农业发展(CRDA)的新概念和框架,作为面对气候变化的农业转型路线图。它还探讨了如何在这一转型过程中解决农业中的性别不平等问题。与气候适应型农业(CRA)不同,CRDA通过整合发展视角,采取了更全面的方法。气候适应型农业仅侧重于调整耕作方式,以减少温室气体排放,并在气候变化面前维持农业生产。其目标是利用行动、方案和政策之间的协同作用,实现气候变化减缓、适应和可持续发展目标,同时解决气候变化给农业部门造成的损失和损害。CRDA框架概述了导致CRDA未来高或低的潜在途径,并强调了性别平等在其结构中的重要性。此外,该研究还强调了在CRDA框架下采取行动加剧或缓解性别差异的潜力,并提出了五项关键行动,有助于农业部门实现性别包容和气候适应型的未来。

This paper presents new evidence on the relationship between farm size and productivity in India's semi-arid tropics, utilizing four decades of data (1975–2014) from ICRISAT's village level studies (VLS). In the context of the agricultural development of India's semi-arid tropics, this period has been associated with a surge in capital-intensive farming practices and declining crop diversity. We present novel evidence on temporal evolution in the farm size-productivity and farm size-efficiency relationship over this period. We control for potential endogeneity of operated land and input use in agriculture by employing fixed effects panel estimation with OLS as well as IV-GMM estimator in the case of productivity analysis and panel SFA for estimating technical inefficiency. We find that, for both measures of productivity—output value per acre and profit per acre—the inverse farm size-productivity relationship has weakened over time, coinciding with the persistent crisis in Indian agriculture. We also find that smallholders operate at a lower level of technical efficiency in value of output per acre but not in terms of profit per acre when compared to their larger counterparts. Furthermore, we find that crop diversification has a negative association with both productivity and technical efficiency. Our findings have implications for the agricultural development policy of the semi-arid tropics.

本文利用ICRISAT村级研究(VLS)的40年数据(1975-2014),提出了关于印度半干旱热带地区农场规模与生产力之间关系的新证据。在印度半干旱热带地区农业发展的背景下,这一时期与资本密集型农业实践的激增和作物多样性的下降有关。我们提出了关于这一时期农场规模-生产力和农场规模-效率关系的时间演变的新证据。我们控制了农业中经营性土地和投入使用的潜在内内生性,方法是在生产率分析中使用固定效应面板估计,在生产率分析中使用IV-GMM估计,在估计技术效率低下时使用面板SFA估计。我们发现,对于生产力(每英亩产值和每英亩利润)这两项指标来说,农场规模与生产力的反向关系随着时间的推移而减弱,这与印度农业持续的危机相吻合。我们还发现,与规模较大的同行相比,小农在每英亩产值方面的技术效率水平较低,但在每英亩利润方面则不然。此外,我们发现作物多样化与生产力和技术效率均呈负相关。本研究结果对半干旱热带地区的农业发展政策具有指导意义。

Current diets in China and worldwide are neither healthy nor sustainable. This paper addresses this challenge focusing on China, which has experienced a rapid dietary transition in recent decades. We investigate how China can improve both health and environmental outcomes by adopting healthy and sustainable diets through a literature review and a food system modeling exercise. We further analyze how policy interventions, including both supply- and consumer-side strategies, can promote the transition toward such diets. The findings provide valuable lessons for other countries facing comparable challenges.

Technological advancements, such as online grocery shopping, have significantly transformed consumer retail environments and experiences. Effectively studying consumer behavior in these new environments requires the use of novel methodological approaches, which will also aid in developing interventions to encourage sustainable consumption. This paper begins by providing an overview of the current literature on novel approaches to analyzing consumer behavior, then provides an empirical application by examining consumer decision-making pathways within an online grocery shopping platform. Specifically, the paper focuses on exploring the consumers' digital footprints, such as page visits, product additions and removals, and interactions with information labels to identify patterns and interests in consumer responses to healthy and sustainable consumption. Findings highlight the potential benefits of integrating consumer search tracking data with environmental design to facilitate informed and conscious food choices.

From Bargaining Power to Empowerment: Measuring the Unmeasurable 从议价能力到授权:测量不可测量的

Measuring power is central to empirical work on intrahousehold and gender relations. This paper reviews how progress in the measurement of power within households has facilitated our understanding of household decision-making and creates new opportunities for programs and policy. Early efforts to test household models focused on measuring spousal bargaining power, usually in models featuring two decision-makers within the household. Proxy measures for bargaining power included age, education, assets, and “outside options” that could affect spouses’ threat points within marriage. Evidence rejecting the collective model of the household has influenced the design of policies and programs, notably conditional cash transfer programs. Efforts have since shifted to measuring empowerment, drawing on theories of agency and power. Since 2010, several measures of women's empowerment have been developed, including the Women's Empowerment in Agriculture Index (WEAI) and its variants. A distinct feature of the WEAI, like other counting-based measures, is its decomposability into its component indicators, which makes identifying sources of disempowerment possible. The WEAI indicators also embody jointness of decision-making or ownership, which better reflects actual decision-making within households compared to 2-person bargaining models. The paper concludes with suggestions for future research.

衡量权力是家庭内部关系和性别关系实证工作的核心。本文回顾了家庭内部权力测量的进展如何促进了我们对家庭决策的理解,并为项目和政策创造了新的机会。早期测试家庭模型的努力主要集中在衡量配偶的议价能力,通常是在家庭中有两个决策者的模型中。衡量议价能力的替代指标包括年龄、教育程度、资产以及可能影响配偶在婚姻中的威胁点的“外部选择”。反对家庭集体模式的证据影响了政策和项目的设计,特别是有条件的现金转移支付项目。从那以后,人们的努力转向了衡量赋权,借鉴了代理和权力理论。自2010年以来,制定了若干妇女赋权指标,包括农业妇女赋权指数(WEAI)及其变体。与其他基于计数的指标一样,WEAI的一个显著特点是它可分解为其组成指标,这使得确定剥夺权力的来源成为可能。WEAI指标还体现了决策或所有权的共同性,与2人议价模型相比,更能反映家庭内部的实际决策。最后,对今后的研究提出了建议。

The WEAI indicators also embody jointness of decision-making or ownership, which better reflects actual decision-making within households compared to 2-person bargaining models.

This paper investigates the analogous land inequality and farm size-productivity relationships, focusing on agricultural total factor productivity (TFP) rather than partial productivity measures. Using a panel of 268 Peruvian districts over a 5-year period (2015–2019), I implement a system generalized method of moments (GMM) estimation framework, which adapts to the presumed data-generating process and structure of the panel while tackling the critical issue of simultaneity bias. The regression output supports both relationships, with a 0.6% increase in agricultural TFP for every one-percentage point reduction of the land Gini coefficient or a one-hectare decrease in average farm size. Moreover, an assessment of the potential impact of land quality heterogeneity and measurement error reveals that neither issue appears to bias the results. Finally, the role of rural reform is discussed, emphasizing the need to weigh the moral considerations of equal opportunity to land of the land-poor against the legitimate property rights of the land-rich on a case-by-case basis.

本文研究了类似的土地不平等和农场规模-生产率关系,重点关注农业全要素生产率(TFP)而不是部分生产率指标。利用5年期间(2015-2019)的268个秘鲁地区的小组,我实施了一个系统广义矩量法(GMM)估计框架,该框架适应了小组假定的数据生成过程和结构,同时解决了同时性偏差的关键问题。回归结果支持这两种关系,即土地基尼系数每降低1个百分点或平均农场规模每减少1公顷,农业全要素生产率就会提高0.6%。此外,对土地质量异质性和测量误差的潜在影响的评估表明,这两个问题似乎都不会影响结果。最后,讨论了农村改革的作用,强调需要在个案基础上权衡土地贫乏者对土地平等机会的道德考虑与土地富裕者的合法财产权。

Despite the extensive use of industry expectations in measuring forecast accuracy and price reactions to USDA reports, very little is known about their properties beyond the basic statistical characteristics of bias, rationality, efficiency, and relative accuracy. Using unique proprietary data of firm-level expectations for upcoming USDA corn and soybean production estimates, we demonstrate that these forecasts exhibit cognitive biases such as attribution and anchoring. Prior success leads to overconfidence and bolder forecasts, and firms base their forecasts on a known reference value. We also show that the bolder the forecasts, the lesser the accuracy, indicating that substantially deviating from the herd does not pay off when it comes to crop production forecasts.

尽管广泛使用行业预期来衡量美国农业部报告的预测准确性和价格反应,但除了偏差、合理性、效率和相对准确性等基本统计特征之外,人们对其属性知之甚少。利用公司对即将到来的美国农业部玉米和大豆产量估计预期的独特专有数据,我们证明这些预测表现出认知偏差,如归因和锚定。先前的成功会导致过度自信和更大胆的预测,而企业的预测是基于已知的参考值。我们还表明,预测越大胆,准确性越低,这表明在作物产量预测方面,大幅度偏离群体是没有回报的。
