FI is associated with increased risk of mortality, coronary heart disease, type 2 diabetes, and some cancers. Despite its impacts, a comprehensive synthesis of the overall weighted pooled prevalence of FI among migrants and refugees in HICs is still lacking. This systematic review and meta-analysis aimed to estimate the pooled prevalence of FI across different migratory groups in HICs. We searched Scopus, Embase, PsycINFO, Medline, and Web of Science for eligible studies published from January 1, 2008 (selected to capture the post-global financial crisis period, when migration patterns changed sharply) to December 16, 2025. Three reviewers independently screened and selected studies, extracted data, and assessed methodological quality. The ‘meta prop’ command in STATA was used to estimate the weighted pooled prevalence of FI among migrants and refugees in high-income countries (HICs). Given the significant heterogeneity among studies (I² &gt; 50%), a random-effects model was used to account for between-study heterogeneity. Additionally, the ‘meta-preg’ command and the likelihood ratio test in Stata were used to examine interactions among gender, region, and FI measurements by publication year. From an initial pool of 758 records, 34 studies met the inclusion criteria. The weighted pooled prevalence of FI among migrants and refugees in HICs was 25.2% (95% CI: 24.3–26.1), indicating that approximately one in four migrants/refugees in high-income countries lacked reliable access to adequate food. The weighted pooled prevalence of FI reported was higher among females (52.7%) than males (46.9%), and scale measures were higher than the rapid measures (34.2% vs. 31.2%). Significant variations were observed across regions. The highest weighted pooled prevalence of FI was found in Europe (60.1%), as opposed to North America (13.8%), the Middle East and North Africa (MENA) region (13.8%), and Oceania (13.3%). The Likelihood Ratio test statistic indicated that FI prevalence varied significantly by gender, region, and FI measurements. Our study shows that one in four migrants or refugees in high-income countries faced FI, particularly among females. The issue is significantly greater in Europe than in other regions. Our findings emphasise the need for global standardisation of FI measurements and for the implementation of targeted interventions and policies to address gender and region-based disparities. These efforts are crucial for promoting equitable food security worldwide. By pursuing more equitable and inclusive strategies, for example, strengthening support for refugees in high-FI regions like Europe and empowering migrant women through targeted programs (e.g., childcare, wage equity, and culturally tailored food supports), stakeholders can improve food security for migrants and refugees worldwid","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1269 - 1289"},"PeriodicalIF":4.5,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01653-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466481","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 examined the food security impact of adopting climate-smart agricultural technologies (CSAT) among 3,371 smallholder staple crop farmers in WASR (Mali and Niger). We used an extended ordered probit and multinomial endogenous treatment effect model to analyze food security impact using two most common response variables: Household Food Insecurity Access Scale (HFIAS) and Household Food Consumption Scores (HFCS). Findings show that several socio-demographic, socio-institutional, location, and bio-climatic factors drive CSAT adoption and food security. Impact results indicate that CSAT adopters are more food insecure than non-adopters. Mechanism analysis reveals that adopters retained a smaller proportion of their crop production for household consumption but generated higher crop revenues through increased market sales. This shift in allocation suggests that while CSAT adoption may enhance financial returns, it can simultaneously undermine household food security when economic gains are not translated into improved dietary access. These findings suggest that farm-level sensitization programs should emphasize the need for farmers to strike a balance between agricultural investment and food security.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 3","pages":"715 - 739"},"PeriodicalIF":6.2,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01654-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147959179","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 Opinion briefly revisits population cultivars methods as instruments for diversity enhancement, local adaptation, and evolutionary responsiveness, by enabling crop cultivars to evolve <i>in situ</i>, and enabling smallholder and local seed networks, where large commercial enterprises are absent or unprofitable. Conventional population-based breeding approaches can (1) value diversity and resilience over short-term maximisation; (2) bring free or minimally charged seed to farmers; and (3) more importantly, farmers can keep seed from one season to the next, while ensuring yield stability. Local seed systems, due to their structural advantages in flexibility and responsiveness resulting from their close connection with farming communities and shorter decision-making pathways, can adapt these breeding tactics more rapidly to emerging challenges, such as climate shocks or sudden changes in farmers demands, create robust local seed systems for marginal growing areas, and mitigate systemic risks under accelerating global change.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 2","pages":"619 - 622"},"PeriodicalIF":6.2,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01663-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147558885","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}

Economic analyses often focus on the outcomes of cooperation while overlooking the diverse institutional mechanisms that shape it. This study aims to address this gap by analysing cooperation within polygynous households as a collective action problem using an adapted version of the Institutional Analysis and Development (IAD) framework. Drawing on ethnographic fieldwork with Fulani and Mossi communities in rural Burkina Faso—which includes participant observation, focus group discussions, Net-Maps, and semi-structured interviews— we examine how rules-in-use shape cooperation regarding agricultural production in polygynous households. Our findings indicate that cooperative outcomes reflect distinct institutional arrangements. Rather than emerging solely from aligned interests, the feasibility of cooperation depends on specific configurations of institutional rules; while some arrangements facilitate collective action by reducing bargaining costs and reinforcing accountability, others—such as rigid gendered taboos—impose institutional barriers that preclude cooperation. In Mossi households, spousal cooperation is driven by mutual dependence and structured incentives. By contrast, in Fulani households, gendered taboos create institutional constraints that lead to an involuntary lack of spousal cooperation. However, this lack of cooperation does not extend to all intrahousehold relations; Fulani co-wives collaborate effectively on private plots enabled by pre-agreed income use and equal sharing norms. This differs sharply from Mossi co-wives who rarely cooperate, due to unequal payoff rules linked to seniority and a lack of formal mechanisms for joint decision-making. These findings demonstrate that cooperation is shaped by the interaction of institutional rules with gender norms, hierarchies, and labour expectations. Consequently, agricultural policies that aim to enhance agricultural productivity and equity must account for this institutional diversity, particularly the varying roles of male provisioning, female autonomy, and collective work.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 3","pages":"791 - 817"},"PeriodicalIF":6.2,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01659-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147959173","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 examines whether increased pulse consumption improves household protein adequacy and reduces early childhood stunting in rural Madagascar, where protein-energy malnutrition remains prevalent. Using a unique high-frequency household panel dataset spanning seven waves from rural central Madagascar collected over three years, combined with concurrent child anthropometric measurements, we estimate the association between pulse consumption and household Protein-Energy Ratios (PERs—a measure of protein adequacy relative to energy intake) and assess whether PERs mediate the pathway linking pulse consumption to child linear growth. Results reveal that a 10-percentage point increase in pulse consumption share within household food expenditure leads to a significant 1.6% improvement in household PERs. Compared to this consumption-share baseline, self-produced and market-purchased pulse consumption showed comparable PER improvements (1.6% and 1.5% per 10-percentage point increase, respectively), as do increased common bean consumption (1.64% improvement) and per capita monthly pulse expenditure (1.86% improvement). Mediation analysis further shows that both contemporaneous and lagged in PER improvements are significantly associated with reductions in early childhood stunting. These findings establish pulses as an effective, accessible intervention for addressing protein-energy malnutrition in smallholder communities. Future research should implement randomized interventions targeting low-consumption households and track sustained nutritional outcomes over longer periods to establish causal pathways between pulse consumption timing and child growth trajectories.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1045 - 1061"},"PeriodicalIF":4.5,"publicationDate":"2026-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01660-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465432","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}

Well-functioning veterinary services are essential for livestock productivity, food safety, and rural resilience, with livestock diseases estimated to cost the region almost US$9 billion annually. However, structural adjustment reforms since the 1980s led to underfunding and a shift towards privatisation and cost recovery, creating inequities in access.

Two socio-economic surveys were conducted to this end in Botswana. Firstly, a general cross-sectional survey of 787 rural households to assess the correlation between food and/or financial security and livestock practices. Secondly, a more nuanced survey of a sub-group of 44 goat-owning smallholders to understand the systemic interlinkages between livelihood outcomes, veterinary care, and goat management. While the importance of livestock to rural communities was confirmed by a positive association with improved food, financial and asset security, household variation was explained more by herd size and self-reported importance of goat ownership to households, than to goat health condition. Four main barriers were identified which negatively influenced goat ownership and herd survivability patterns: (1) low turnover rates and poor access to capital investment; (2) Limited use of supplementary feeds; (3) Poor access to veterinary services; and (4) Age and gender.
