This study investigates the relationship between farm production diversity and household dietary diversity and food security in five climate-vulnerable districts of southern Bangladesh. Data were collected from 768 households between April and June 2023 using structured surveys stratified by salinity zones. Dietary diversity was measured through household dietary diversity scores and food variety scores, while food insecurity was assessed using the Household Food Insecurity Access Scale. Farm production diversity was quantified by the number of food groups produced, the Shannon diversity index, and food crop diversity. Poisson and ordered probit regression models were applied to estimate associations, controlling for market access, off-farm household income, household demographics, and environmental factors. The results reveal that greater production diversity is modestly but significantly associated with improved dietary diversity and reduced food insecurity, particularly in low and medium salinity zones. In high salinity areas, these associations were weaker or statistically insignificant, likely reflecting environmental constraints limiting production options. Market access, off-farm household income, education, and household size also played significant roles. These findings underscore the need for context-specific strategies that integrate production diversification with climate-resilient technologies, livelihood diversification, and improved market access to strengthen food security in climate-vulnerable rural communities.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 1","pages":"221 - 239"},"PeriodicalIF":6.2,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-025-01620-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147339299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the relationship between heatwave patterns and grain yields in China, a critical region for global food security. We utilized the Mann-Kendall (MK) test, bivariate correlation analysis, and network structure similarity (NSS) analysis to examine data spanning from 1961 to 2020 across Chinese provinces. The study results show that over the past six decades, 93.5% of China’s 31 provinces have seen a significant increase in heatwave frequency, which has primarily negatively correlated with grain yields, particularly with summer grain yields. In 22 major summer grain-growing provinces, over 70% of cases show a significant correlation between heatwaves and summer grain yields. Specifically, 9 provinces exhibit linear correlations, while 7 show nonlinear correlations. This correlation has further intensified over the past 40 years. Yunnan and Guangxi have the highest heatwave-related summer grain yields, averaging 1200 kg/ha annually (21.9% of the national average in 2020). Guizhou and Ningxia average 1000 kg/ha, while other provinces average less than 310 kg/ha. Heatwaves across most regions of China demonstrate an increasing trend, exhibiting predominantly negative correlations with grain yields - particularly summer grain. This study pioneers a novel quantification framework for assessing heatwave-induced yield impacts, providing a robust basis for analyzing the climate-food security nexus and developing targeted mitigation strategies.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 1","pages":"195 - 217"},"PeriodicalIF":6.2,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147338429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mediation analysis indicates that income partially explains the relationship between digital extension services and food security, particularly for female-headed households, underscoring the need for targeted interventions that enhance women’s economic participation in agriculture.

System Dynamics (SD) can model complex, dynamic systems with feedback loops. Using an SD model, we explore how FW and human behavior interact and identify major drivers and feedback mechanisms in HK FW management (FWM) practices. Subsequently, we simulated scenarios on population growth, economic awareness of FW recycling, and facility efficiency. Without new policies or action plans, FW is projected to grow steadily over the modeled period. We found that raising economic awareness (penalties and incentives) is the optimal solution, reducing daily per capita FW to 0.343 kg. In contrast, the assumed population growth scenario is the most severe, with per-capita waste could climb to 0.439 kg/day by 2040. Contrary to many studies that predominantly focused on improving the efficiency of recycling facilities, we emphasized changing people’s awareness through economic means such as charging and incentives being the most useful means of reducing FW.

This article fills this gap by utilizing the Food and Agriculture Organization’s framework for studying food security, which encompasses availability, access, utilization, and stability. Through 27 semi-structured interviews, the study explores how refugees handle food insecurity, including by limiting food quantity and diversity, borrowing money and food, and prioritizing children’s nutrition. Furthermore, the study highlights the governance dimension of food security, demonstrating how policies and market forces affect refugees’ vulnerability to hunger. By adopting a qualitative approach focused on migrants’ narratives and experiences, this article provides a nuanced, micro-level understanding of food insecurity.
