This study examines how environmental and demographic pressures influence food security, measured using the Food Production Index (FPI) as a proxy for national food availability. Specifically, the study investigates the effects of land degradation, fertilizer consumption, grazing land pressure, permanent cropland, and population density on food security in Nigeria. Using quarterly data from 1990 to 2023, the study applies the Modified Kernel Regularized Quantile Regression (MKRQR) approach to capture nonlinear and heterogeneous effects across different levels of food security. The results reveal that land degradation and grazing pressure consistently exert significant negative effects across most quantiles of the food production distribution, indicating that environmental stress undermines food system performance. In contrast, permanent cropland expansion, fertilizer consumption, and population density generally enhance food security, although the magnitude of these effects varies across quantiles. These findings highlight that the determinants of food security operate differently across the distribution of food production. The study recommends targeted policy interventions including land restoration initiatives, sustainable cropland management, improved fertilizer accessibility and efficiency, and integrated land-use planning to strengthen Nigeria’s long-term food system resilience.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1355 - 1377"},"PeriodicalIF":4.5,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011519","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}

Climate change has thus emerged as a frontline threat to sustainable food security, intensifying multiple abiotic stresses across agricultural systems. Abiotic stresses seldom appear in isolation; instead, they often interact, both among themselves and with biotic stressors under field conditions. This results in compounded impacts that are difficult to quantify and manage under field conditions. This opinion article highlights the importance of quantifying and managing abiotic stressors under the rapidly changing climate to achieve food security. Here, we provide a brief overview of major abiotic stress types classified as atmospheric, edaphic, and water stresses, and propose a conceptual framework for analysis and decision making. This opinion article argues that localized, context-specific strategies are essential for agricultural adaptation and mitigation, considering the spatiotemporal impacts, magnitude and frequency of stresses, as well as the vulnerability and resilience of the farming system to abiotic stresses. Future research must prioritize the quantification of multiple stressors and the development of integrated stress management strategies. By aligning global agricultural innovation with local needs and sustainability goals, resilient food production systems can be built that may meet the growing world food demand.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"855 - 860"},"PeriodicalIF":4.5,"publicationDate":"2026-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465001","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}

However, spatial mismatches between food production and consumption continue to undermine the resilience and equity of food systems. This study examines the structural characteristics of the food production-consumption system in Shanxi, China, over the period 2005–2020, focusing on spatial risks toward food availability. A Gaussian Two-Step Floating Catchment Area (Ga2SFCA) method was used to quantify the spatiotemporal coupling between staple grain production and consumption, while migration in production centers was analysed using geographic centroid tracking. Results reveal a growing disparity between dominant feed-oriented maize production and insufficient staple grain availability for human consumption, especially in densely populated areas with limited arable land. From 2005 to 2020, the center of maize production migrated from Qingxu to Qixian, while the center of wheat production moved from Xiangfen to Quwo. Urban food consumption increased steadily (11.85 × 10⁴ tons per year), while rural consumption declined (11.96 × 10⁴ tons per year), amplifying spatial imbalances in food accessibility. Despite improvements in county-level production-consumption ratios under expanded food distribution thresholds, a persistent structural deficit remains, requiring reliance on interregional food transfers. These findings reveal underlying spatial vulnerabilities within Shanxi’s food system and provide policy-relevant insights for enhancing intra-provincial coordination and supply resilience. The integrated remote sensing-spatial analysis framework offers a transferable approach for assessing food system vulnerabilities in other regions pursuing SDG 2 (Zero Hunger) and SDG 17 (Partnerships).</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 5","pages":"1599 - 1617"},"PeriodicalIF":4.5,"publicationDate":"2026-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011521","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}

Utilizing Colombia’s recent ratification of the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) as a case study, this research explores how participation in the Treaty’s Multilateral System (MLS) can strengthen national agricultural innovation by mitigating legal and transactional barriers to germplasm exchange and conservation. We analyze four case studies encompassing cassava, forage grasses, bananas, and beans to quantify both realized and potential benefits derived from international germplasm flows. Two ex-post cases demonstrate that the adoption of foreign-derived materials has already yielded considerable economic gains in Colombia, including US$1.62 million from the TAI-8 cassava variety and significant productivity improvements from Brachiaria forages, which now cover 32% of the nation’s pastures. Two ex-ante cases illustrate that continued access to foreign genetic resources is crucial for addressing major emerging threats, with potential losses exceeding US$9 billion from cassava brown streak disease in Africa and up to US$700 million annually for Colombia’s banana sector under a scenario of full Fusarium TR4 spread. The analysis further reveals that Colombia is already deeply integrated into global germplasm exchange through CGIAR collections governed by Article 15 of the Treaty, accounting for approximately 87% of all MLS distributions worldwide. However, prior to ratification, national institutions faced considerable legal and institutional constraints concerning the exchange and safe duplication of their own collections, including an inability to deposit materials in the Svalbard Global Seed Vault. Collectively, these findings underscore that germplasm exchange has long been a pivotal driver of agricultural advancement in Colombia and that Treaty participation offers essential institutional infrastructure to secure, govern, and amplify these benefits within a more regulated and equitable global framework. Despite these advances, important challenges remain in ensuring fair and equitable benefit-sharing, particularly for farmers, highlighting the need for continued institutional and policy development within the MLS.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1247 - 1268"},"PeriodicalIF":4.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01678-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465055","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}

The increasing fragility of world agrifood systems and rising inequalities further impede the provision of adequate, nutritious, and safe diets. This study uses bibliometric methods to analyse 6,885 articles on food security indexed in the Web of Science Core Collection (1990–2022), showing the evolution of concepts, paradigms, and methods in the field. Academic output grew at an average annual rate of 47%, with the USA, the United Kingdom, and China dominating in publication volume and international cross-citation. Three interconnected evolution dimensions were identified. As a concept, food security expanded from a three-dimensional framework (including food “availability” – i.e., food production), to a six-dimensional one, centred on the right to food, reflecting a shift from a production-centric perspective to a more comprehensive, multi-level understanding. Paradigmatically, three core shifts— (1) from yield increase to sustainable food production, (2) from food supply to agrifood systems, and (3) from single-discipline to multidisciplinary research—collectively constitute the core logic underpinning the global transition from food production-oriented approaches to sustainable systems thinking. Methodologically, research evolved from local-scale crop studies and modelling, to regional-scale studies including computable general equilibrium models and remote sensing, and further on, to global-scale earth system analysis and models, artificial intelligence, and system dynamics. Such an evolution led to research priorities shifting from local yield-oriented targets, to (eco)regional studies emphasising systems sustainability, to food system transformation, and to sustainable governance of food systems. However, the systemic linkages between food security and adjacent fields—including water security, energy security, water footprint, and environmental sustainability—remain underexplored and warrant further investigation. Bibliometric methods rely on citation and co-occurrence frequency as reliable indicators, but this can lead to the neglect of low-density, high-theoretical-value topics. Therefore, future research should combine systematic reviews to overcome this limitation. The present work offers an in-depth analysis of the evolving research paradigms in the very broad domain of food security and provides guidance for future research directions.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1307 - 1322"},"PeriodicalIF":4.5,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465058","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}

Using a combination of parametric and non-parametric tests and a Multinomial Endogenous Treatment Effect model, the results showed that CSA practices are most adopted in the Sudano-Guinean zone and least adopted in the Sahelian zone. In addition, sorghum-producing farmers, relative to maize-producing farmers, are less likely to adopt CSA practices, such as crop diversification. Household size and access to extension agents are the two factors that positively influence the adoption of most CSA practices. Regarding the impact analysis, we find that minimum tillage is the only CSA practice that significantly reduces cereal-producing household food insecurity (by 94%), whereas all five CSA practices significantly improve household dietary diversity scores (especially by 50% and 30% for the change of sowing dates and crop diversification, respectively).

This study used a Generalized Structural Equations Modeling (GSEM) approach to assess the impact of pandemic related changes in income and the labour market on food insecurity among Egyptian households, based on data from the COVID-19 MENA Monitor rapid phone surveys (CMMHH). GSEM results indicate that individuals in the highest income quartile are 36% less likely to experience severe food insecurity, but more likely to face moderate (+ 7%) and low (+ 29%) food insecurity compared to those in the lowest quartile. Conversely, households with declining income are 12% more likely to suffer severe food insecurity. Respondents who were temporarily or permanently laid off are significantly more vulnerable, with a 17% and 8% increased probability, respectively, of experiencing severe food insecurity. Additionally, those who experienced income deterioration are 7% more likely to suffer severe food insecurity. Demographic factors also play a significant role where women are 7% more likely to face severe food insecurity than men. Highly educated individuals are less likely to experience severe food insecurity (-10%) but more likely to face moderate (+ 3%) or low (+ 6%) food insecurity. A larger household size also increases the risk: each additional member raises the probability of severe food insecurity by 2%. The findings confirm the significant impact of changes in income, employment status, and demographic factors on food insecurity during the COVID-19 crisis.
