As many countries, including China, experience rapid population aging, new challenges emerge for reducing food-related carbon emissions. Variations in dietary preferences and entrenched eating habits across age groups introduce substantial uncertainty into projections of future dietary carbon footprints. This study analyzes age-specific dietary carbon emissions, simulates the impact of demographic aging on China's food-related emissions, and explores the drivers of dietary transitions. Using microdata from the 2014 China Urban Household Survey, we simulate the effects of demographic changes—both in population size and structure—and potential shifts in dietary behavior. The results indicate that total dietary carbon emissions are likely to peak and then decline around 2030 due to population contraction. However, per capita emissions will increase as the population ages. Health-oriented dietary transitions and technological advancements in agriculture could reduce emissions by approximately 10 %–13 % and 22 %–26 %, respectively. Although the dietary system may face reduced carbon pressure, other systemic risks could arise. Notably, aging may lead to a decline in the agricultural workforce, exacerbating mismatches between labor supply and food demand, and posing additional risks to food security. These findings underscore the need for improved agricultural efficiency, technological innovation, and a carefully coordinated approach to urbanization and rural revitalization strategies.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"46 ","pages":"Article 100875"},"PeriodicalIF":9.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144686502","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}

Climate change is expected to further exacerbate these challenges. Agroecological systems are increasingly promoted as a viable solution toward more resilient, nutritious, sustainable, and climate-adaptive food systems. However, the mechanisms linking biodiversity and climate sensitive management practices with potential nutritional contributions in these food production systems remain underexplored. In agroecosystems, the functional diversity of ecological traits supports resilience to disturbance and food security, while the functional diversity of nutritional traits influences the system's nutritional potential to support nutritional adequacy and human health. Using a trait-based framework, we quantified ecological and nutritional functional diversity in 48 Indigenous agroforests in Fiji. We found that agroforests with higher ecological functional diversity of response traits exhibit significantly greater nutritional functional diversity, suggesting that managing for ecological resilience may also enhance the nutritional potential of food production systems.

The higher productivity among male-managed plots is primarily driven by differential access to inputs, including labour and non-labour inputs, managerial and household characteristics. Compared to jointly managed plots, the results suggest a nuanced relationship for female-managed plots with a non-significant relationship in northern and southern Nigeria, Ethiopia, and Tanzania, whereas female-managed plots are more productive in Uganda and less productive in Malawi.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"46 ","pages":"Article 100872"},"PeriodicalIF":9.8,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144662701","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 combines multi-disciplinary reflections on the pathways towards more resilient and inclusive rural transformation. We first identify four well-established nutrition challenges to addressing: i) rural inequality in building human capital and its associated social determinants for rural transformation; ii) rising double malnutrition burdens in low- and middle-income countries; iii) recognizing that food environment is a key determinant of access to healthy diets; and iv) profound inequality in dietary and nutrition outcomes under an increasing number of shocks. We consider these challenges alongside four emerging priorities that require greater emphasis for resilient and inclusive rural transformation: i) Explicit focus on inclusivity; ii) Respecting Indigenous people's roles; iii) Addressing spatial changes to rural landscapes and implications on dietary transitions; and iv) Considering rural livelihood diversification, migration, and food environment for resilient and inclusive rural transformation. Finally, we propose expanding existing agricultural pathways towards improved diets for nutrition by integrating a stronger focus on gender, climate adaptation and resilience, policy coherence, and value chain linkages to address multiple forms of malnutrition while remaining within planetary boundaries.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"46 ","pages":"Article 100871"},"PeriodicalIF":9.8,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144605920","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}

While remarkable progress has been made in drought and food insecurity research, relatively few studies have attempted to capture the inherent complexity of the drought-food insecurity nexus, particularly the interactions and feedback between ecological and social systems. An example of a feedback loop is that, as drought reduces crop production and heightens food insecurity, it can also lead to greater reliance on irrigation, which in turn depletes water resources, thereby exacerbating drought conditions. Moreover, the traditional approach of viewing drought as a natural phenomenon and food insecurity as a social phenomenon indicates flaws in assessing and monitoring the drought-food insecurity nexus. In this perspective, we propose a social-ecological systems (SES) approach that holistically integrates these dimensions, emphasizing the complex interactions and feedback that characterize the drought-food insecurity nexus. We also present a conceptual SES model developed in the context of the regional drought-food insecurity nexus in Bangladesh and discuss its implications in future research. We argue that cross-sectoral collaboration is needed for identifying leverage points and designing policy interventions to achieve food security targets. We also suggest that future research needs to consider all the complex relationships and trade-offs between social and ecological systems to inform sustainable policy development relating to achieving food security (SDG 2) by 2030 and long-after.</div></div>","PeriodicalId":48741,"journal":{"name":"Global Food Security-Agriculture Policy Economics and Environment","volume":"46 ","pages":"Article 100874"},"PeriodicalIF":9.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596161","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}

Our starting point for the meta-analysis was the Agriculture in the Digital Age Evidence Gap Map dataset, which provided a consistent set of studies of digital interventions, though one limitation is that it excludes more recent studies published after 2021. After applying our criteria for relevance, rigor, and availability of necessary data, we used estimates from 20 studies in our analyses where fifteen were from Sub-Saharan Africa, four from India, and one from Cambodia. Mean impacts of digital information interventions on adoption of fertilizer (+23 %; 95 % CI +6 % to +40 %), yield (+6 %; +2 % to +9 %), and income (+6 %; +2 % to +9 %) are positive while effects on adoption of improved seeds were not statistically significant. Although our analysis indicates that digital farmer services have provided benefits on average, there is considerable variability in estimates across individual studies. However, there are not enough comparable quantitative observations from the literature included within our study population to reliably further disaggregate estimated impacts (e.g., by intervention, level of human assistance, geography, modality of information delivery, farmer type).
