In the 21st century, technological innovation has become a crucial driver of economic transformation. It also contributes to agricultural performance, particularly through its influence on research intensity and labor productivity growth. However, its specific implications for agricultural performance in the ASEAN region remain insufficiently examined. Since the agricultural sector is essential for ensuring food security and sustaining rural livelihoods, understanding the intersection between innovation and agricultural outcomes becomes indispensable. This study explores how technological innovation impacts agricultural performance in the ASEAN region from 2000 to 2022, emphasizing the moderating role of digitalization. Using the Panel-Corrected Standard Errors (PCSE) model alongside various robustness tests, the study identifies several key findings. (1) Technological innovation enhances agricultural performance. (2) Technological innovation improves agricultural performance by increasing agricultural research intensity and labor productivity growth. (3) Digitalization positively moderates the effect of technological innovation on agricultural performance. (4) Digitalization further amplifies the impact of technological innovation on the production of crops, livestock, fisheries, agri-value added, and agri-export. (5) Heterogeneity analysis indicates that ASEAN countries with high levels of economic growth, agricultural reliance, and education experience the most significant benefits from technological innovation in agriculture. Hence, the study offers novel insights for policymakers at both macro and micro levels, advocating for improved regional collaboration, digital infrastructure, research and development, capacity building, and institutional reforms to foster technology-driven agricultural transformation in the ASEAN region.

在21世纪，技术创新已成为经济转型的关键驱动力。它还有助于农业绩效，特别是通过其对研究强度和劳动生产率增长的影响。然而，它对东盟区域农业绩效的具体影响仍未得到充分审查。由于农业部门对确保粮食安全和维持农村生计至关重要，因此了解创新与农业成果之间的交集就变得必不可少。本研究探讨了2000 - 2022年东盟地区技术创新对农业绩效的影响，强调了数字化的调节作用。使用面板校正标准误差（PCSE）模型以及各种稳健性测试，该研究确定了几个关键发现。(1)技术创新提高农业绩效。(2)技术创新通过提高农业科研强度和劳动生产率提高农业绩效。(3)数字化正向调节技术创新对农业绩效的影响。(4)数字化进一步放大了技术创新对作物、畜牧业、渔业生产、农业附加值和农产品出口的影响。(5)异质性分析表明，经济增长水平、农业依存度和教育水平较高的东盟国家从农业技术创新中获得的收益最为显著。因此，该研究为宏观和微观层面的政策制定者提供了新颖的见解，倡导改善区域合作、数字基础设施、研发、能力建设和制度改革，以促进东盟地区技术驱动的农业转型。

Reducing household food waste (HHFW), one of the major contributors to total food waste, is a critical responsibility shared by food researchers and policymakers. To date, researchers have examined the drivers of HHFW and proposed various recommendations to mitigate it. Although the growing body of literature on HHFW interventions has generated valuable insights, several limitations—such as methodological inconsistencies, narrow scope, missing variables, concerns over reliability, and limited research designs—complicate meaningful comparisons and hinder the aggregation of findings across studies. Moreover, while numerous intervention strategies have been proposed and implemented, their effectiveness often remains underexplored or is assessed within the constraints of these limitations. The Fuzzy Cognitive Map (FCM) methodology presents a unique opportunity for food policy researchers to investigate the effectiveness of food waste prevention activities and interventions. We argue that FCM holds this potential because it offers a consistent analytical foundation, supported by theoretical frameworks and prior findings, through which diverse intervention alternatives can be tested and compared. Accordingly, following the construction of a fuzzy cognitive map of HHFW—based on a comprehensive review of the literature and expert assessment—this paper aims to utilize the FCM to determine and compare the HHFW-reduction capacity of various real-world intervention alternatives. Our findings highlight the strong potential of specific emerging retail formats (e.g., zero-packaging grocery stores) and manufacturing technologies (e.g., intelligent fridges) to reduce HHFW, although both require careful implementation to achieve their intended impact. Commonly employed interventions, such as informational campaigns, may prove ineffective when used in isolation and should therefore be complemented by other types of interventions. Online shopping—an increasingly prevalent food purchasing behavior—can substantially contribute to HHFW, underscoring the need for practitioners to consider the potential negative consequences of algorithm-driven purchasing systems. We provide an in-depth discussion of these findings, examine the study’s limitations, and elaborate on their implications for consumers, producers, distributors, and policymakers.

减少家庭食物浪费（HHFW）是食物浪费总量的主要来源之一，是食品研究人员和政策制定者共同的重要责任。迄今为止，研究人员已经研究了HHFW的驱动因素，并提出了各种缓解建议。尽管越来越多的关于HHFW干预的文献产生了有价值的见解，但一些局限性——如方法不一致、范围狭窄、缺少变量、对可靠性的担忧和有限的研究设计——使有意义的比较复杂化，并阻碍了研究结果的汇总。此外，虽然已经提出和实施了许多干预策略，但它们的有效性往往仍未得到充分探索或在这些限制的限制下进行评估。模糊认知图（FCM）方法为食品政策研究人员提供了一个独特的机会来调查食物浪费预防活动和干预措施的有效性。我们认为FCM具有这种潜力，因为它提供了一个一致的分析基础，由理论框架和先前的研究结果支持，通过它可以测试和比较不同的干预方案。因此，在综合文献回顾和专家评估的基础上，构建了一个hhfw的模糊认知图，本文旨在利用FCM来确定和比较各种现实世界干预方案的hhfw减少能力。我们的研究结果强调了特定的新兴零售业态（例如，零包装杂货店）和制造技术（例如，智能冰箱）在减少HHFW方面的巨大潜力，尽管两者都需要仔细实施才能实现预期的影响。通常采用的干预措施，如宣传运动，如果单独使用可能是无效的，因此应辅以其他类型的干预措施。网上购物——一种日益流行的食品购买行为——可以极大地促进HHFW，强调从业者需要考虑算法驱动的购买系统的潜在负面影响。我们对这些发现进行了深入的讨论，考察了研究的局限性，并详细阐述了它们对消费者、生产商、分销商和政策制定者的影响。

According to the IPCC’s Fifth Assessment Report, “It is projected that climate change will affect food security by the middle of the 21st century, with the largest numbers of food-insecure people located in South Asia”. Therefore, it is important to understand how higher temperatures impact nutrition. In this paper, we use three rounds of nationally representative consumption data to examine the impact of high temperatures on food consumption in India. We find that the overall effects of temperature on macronutrient intake, food and dietary diversity are small and economically insignificant. The consumption of non-perishable food items such as cereals remains unaffected during hot periods. However, we find significant negative effects on nutrition obtained from perishable food items. For example, a 1 °C increase in mean temperature over a 30-day period leads to a decline of about 2% in protein consumption from meat, fish, and eggs in rural areas. The adverse effects on perishable food consumption are more pronounced among poorer households and those lacking access to refrigeration, in both rural and urban areas. Given the disproportionate burden on low-income households, our findings call for targeted policy responses to safeguard food and nutrition security in the face of climate change.

根据IPCC第五次评估报告，“预计到21世纪中叶，气候变化将影响粮食安全，南亚的粮食不安全人口数量最多”。因此，了解高温如何影响营养是很重要的。在本文中，我们使用三轮全国代表性的消费数据来检查高温对印度食品消费的影响。我们发现，温度对宏量营养素摄入量、食物和膳食多样性的总体影响很小，在经济上也不显著。在炎热的季节，谷物等不易腐烂的食品的消费不受影响。然而，我们发现从易腐食品中获得的营养有显著的负面影响。例如，30天内平均气温每升高1℃，农村地区的肉类、鱼类和蛋类蛋白质消费量就会下降约2%。对易腐食品消费的不利影响在农村和城市地区较贫穷的家庭和无法获得冷藏设备的家庭中更为明显。鉴于低收入家庭承受着不成比例的负担，我们的研究结果呼吁采取有针对性的政策应对措施，在气候变化面前保障粮食和营养安全。

Adopting sustainable food consumption (SFC) is essential for addressing climate change, improving health outcomes and achieving the Sustainable Development Goals (SDGs). However, little is known about what encourages people to make a lasting shift to SFC. This research considers a future design (FD) approach where people are asked to think about a problem and to act through taking a perspective of future generations, investigating the question “how does the FD approach impact food consumption?” and the hypothesis “FD induces a lasting shift to SFC.” We employ a social experiment with three treatments of “control group,” “deliberation” and “FD,” collecting data on organic and nonorganic vegetable consumption with 300 households in Bangladesh over three months. In the control group, households report the consumption. In deliberation, they additionally deliberate among their family members to think of a vision, a mission and a strategy for the consumption. In the FD treatment, participants additionally consider the perspectives of past, current and future generations before deliberating on the same issues. Results indicate that FD affects people to have a sustained increase (decrease) in organic (nonorganic) vegetable consumption as compared to any other treatment, and the effect under FD is approximately twice as much as that under deliberation in magnitude and in each round. Overall, FD demonstrates a great potential for inducing people to make a persistent change to SFC.

采用可持续粮食消费（SFC）对于应对气候变化、改善健康成果和实现可持续发展目标（sdg）至关重要。然而，究竟是什么促使人们长期转向SFC，我们所知甚少。本研究考虑了一种未来设计（FD）方法，要求人们思考一个问题，并通过从子孙后代的角度出发采取行动，调查“FD方法如何影响食物消费？”我们采用了“对照组”、“审议组”和“FD组”三种处理方式的社会实验，收集了孟加拉国300户家庭三个月来有机蔬菜和非有机蔬菜的消费数据。在对照组中，家庭报告消费情况。在审议过程中，他们还会在家庭成员之间进行审议，思考消费的愿景、使命和策略。在FD治疗中，参与者在审议同一问题之前还会考虑过去、现在和未来几代人的观点。结果表明，与任何其他治疗相比，FD影响人们有机（非有机）蔬菜消费量的持续增加（减少），并且在每个回合中，FD的效果大约是审议效果的两倍。总的来说，FD展示了诱使人们对SFC进行持久改变的巨大潜力。

Despite efforts to improve food and nutrient intake in the last decades, child undernutrition remains a challenge, particularly in rural areas of developing countries. Although household labor reallocation after weather shocks is an important ex-post strategy to mitigate weather-shock impacts, a comprehensive understanding of how households adjust their labor and its implications in the context of child health is lacking. We investigate how different forms of labor activity is associated with the impacts of rainfall shock on child nutritional status, using nationally representative panel data from rural households in Bangladesh, in conjunction with monthly precipitation and temperature data for the last three decades. We find that less rainfall during the main cropping season in the previous year worsens nutritional status of children under the age of five years, while less rainfall in the current year increases child nutrition. We also find heterogeneous associations of different types of labor with the identified linkages between rainfall shock and child nutritional status. While maternal off-farm self-employment plays a potential role in mitigating the negative impact of rainfall shortage, maternal on-farm labor may worsen child nutrition under rainfall shocks. We do not find any significant associations for household-level total labor time and other household members’ labor time. Our results therefore underscore the importance of providing sufficient off-farm employment opportunities for mothers and addressing maternal time constraints through targeted policies to cope with extreme weather and improve child nutrition.

尽管过去几十年来努力改善食物和营养摄入，但儿童营养不良仍然是一个挑战，特别是在发展中国家的农村地区。虽然天气冲击后家庭劳动力的重新分配是减轻天气冲击影响的重要事后策略，但对家庭如何调整劳动力及其对儿童健康的影响缺乏全面的了解。我们调查了不同形式的劳动活动与降雨冲击对儿童营养状况的影响之间的关系，使用了孟加拉国农村家庭的全国代表性面板数据，并结合了过去三十年的月度降水和温度数据。研究发现，前一年主要种植季降雨量少会使5岁以下儿童的营养状况恶化，而今年降雨量少则会增加儿童的营养状况。我们还发现不同类型的劳动与降雨冲击和儿童营养状况之间确定的联系的异质关联。虽然母亲的非农就业在缓解降雨短缺的负面影响方面发挥着潜在的作用，但母亲的农业劳动力可能会使降雨冲击下的儿童营养状况恶化。我们没有发现家庭总劳动时间与其他家庭成员劳动时间有显著的关联。因此，我们的研究结果强调了为母亲提供足够的非农就业机会以及通过有针对性的政策应对极端天气和改善儿童营养来解决母亲时间限制的重要性。

The literature extensively documents the nutritional impact of School Milk Programs (SMPs) on school-going children. Nonetheless, a gap exists regarding the identification of mechanisms influencing the placement and implementation of SMPs. This paper presents new insights regarding the mediated role of local governments, parent-teacher associations (PTAs), and dairy cooperatives in connection with SMP’s association with child nutrition. This study utilizes exogenous historical variations in the establishment of village-level dairy cooperative societies and randomly assigned political reservations for women in Indian local governments to examine the relationship between SMPs and nutritional outcomes for school-going children. The findings indicate a 14.6% drop in the probability of HAZ score falling below −2σ and a 14.3% reduction in the likelihood of being underweight among the school-going children. The mediated effects of women’s reservations in local governments and the presence of PTAs on the z-scores of height-for-age and weight-for-age are 0.27σ and 0.19σ, respectively.

文献广泛记录了学校牛奶计划（SMPs）对学龄儿童的营养影响。尽管如此，在确定影响smp安置和实施的机制方面仍存在差距。本文提出了关于地方政府、家长教师协会（pta）和乳制品合作社在SMP与儿童营养关系中的中介作用的新见解。本研究利用村级乳品合作社建立过程中的外生历史变化，以及印度地方政府中随机分配的妇女政治保留地，来检验SMPs与学龄儿童营养状况之间的关系。研究结果表明，在学龄儿童中，HAZ得分低于- 2σ的可能性下降了14.6%，体重不足的可能性下降了14.3%。女性在地方政府的保留地位和ta的存在对年龄身高和年龄体重z得分的中介作用分别为0.27σ和0.19σ。

Existing research on nutritional assistance largely focuses on its short-term effects. Using data from the 2019 China Household Finance Survey (CHFS), this research investigates the long-term effects, underlying mechanisms, and cost-effectiveness of the Nutrition Improvement Program (NIP), a widespread school meal program in rural China, on students’ educational attainment. Our findings indicate that the NIP significantly increases the likelihood of students attending high school and college and extends their years of education. These results are robust across various sensitivity tests. The NIP improves educational attainment by enhancing students’ health, cognitive abilities, non-cognitive skills, and parental educational expectations. Furthermore, the impact is more pronounced among students with lower parental education levels and those in western regions. A cost-benefit analysis shows that the economic returns of the NIP surpass its costs, highlighting its substantial economic efficiency. This research underscores the importance of school meal programs as a human capital investment and provides valuable insights for policymakers in China and other developing nations seeking to address educational inequality and improve population health and well-being.

目前关于营养援助的研究主要集中在其短期效果上。本研究利用2019年中国家庭财务调查（CHFS）的数据，调查了营养改善计划（NIP）对学生教育成就的长期影响、潜在机制和成本效益。营养改善计划是中国农村广泛开展的一项学校供餐计划。我们的研究结果表明，NIP显著增加了学生上高中和大学的可能性，并延长了他们的受教育年限。这些结果在各种灵敏度测试中都是可靠的。NIP通过提高学生的健康、认知能力、非认知技能和家长的教育期望来提高受教育程度。此外，这种影响在父母教育程度较低的学生和西部地区的学生中更为明显。成本效益分析表明，NIP的经济收益超过其成本，突出了其可观的经济效率。这项研究强调了学校供餐计划作为人力资本投资的重要性，并为中国和其他发展中国家寻求解决教育不平等和改善人口健康和福祉的政策制定者提供了有价值的见解。

This research underscores the importance of school meal programs as a human capital investment and provides valuable insights for policymakers in China and other developing nations seeking to address educational inequality and improve population health and well-being.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"135 ","pages":"Article 102915"},"PeriodicalIF":6.8,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper assesses the impact of agricultural technology adoption on poverty beyond headcount in Tanzania. Specifically, the paper examines the effects of adopting yield-increasing technologies, such as organic fertilizers and improved seeds, as well as risk-reducing technologies, including intercropping, on multidimensional poverty using panel data and an instrumental variable econometric approach. We find that the adoption of climate-smart technologies reduces the risk of a household being deprived in multiple non-monetary welfare dimensions. The largest impact on multidimensional poverty is achieved when these technologies are adopted in combination. Furthermore, adopting the full package of technologies has a more significant impact than adopting either a single technology or a combination of the two. The results also indicate that improved agricultural productivity and increased income from agricultural sales are key mechanisms through which CSA technologies reduce poverty. These findings underscore the importance of promoting bundled CSA adoption strategies to maximize poverty reduction and resilience among smallholder farmers.

本文评估了坦桑尼亚农业技术采用对人口以外贫困的影响。具体而言，本文使用面板数据和工具变量计量经济学方法检验了采用增产技术（如有机肥和改良种子）以及降低风险技术（包括间作）对多维贫困的影响。我们发现，采用气候智能型技术降低了家庭在多个非货币福利维度上被剥夺的风险。只有将这些技术结合起来加以采用，才能对多维贫困产生最大影响。此外，采用整套技术比采用单一技术或两者的组合具有更大的影响。研究结果还表明，提高农业生产率和增加农产品销售收入是CSA技术减少贫困的关键机制。这些发现强调了推广捆绑CSA采用战略的重要性，以最大限度地减少小农的贫困和抵御能力。
