This paper investigates the association between household aquaculture engagement, dietary diversity and children’s anthropometric outcomes, specifically height-for-age z-scores (HAZ) and stunting prevalence, utilizing longitudinal data from rural Bangladesh. Our findings demonstrate that households engaged in aquaculture exhibit substantially enhanced food security indicators, including significantly greater consumption of home-produced foods and fish, and higher dietary diversity scores compared to non-aquaculture households. Notably, we identify a significant interaction effect whereby female children in households characterized by both aquaculture engagement and higher levels of women’s empowerment demonstrate significantly higher HAZ scores and reduced stunting risk. These empirical results suggest that the synergistic combination of household aquaculture systems and women’s empowerment represents a critical pathway for enhancing household food security and mitigating child malnutrition—with particularly pronounced benefits for female children—in rural Bangladesh contexts. The findings have substantial implications for integrated intervention strategies targeting both aquaculture development and women’s empowerment in similar low- and middle-income country settings.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"135 ","pages":"Article 102944"},"PeriodicalIF":6.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144891869","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}

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.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"135 ","pages":"Article 102939"},"PeriodicalIF":6.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144829023","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}

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.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"135 ","pages":"Article 102927"},"PeriodicalIF":6.0,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144724346","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}

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.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"135 ","pages":"Article 102919"},"PeriodicalIF":6.0,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144724345","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}

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.

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.
