In Côte d’Ivoire, the harvested fruit is either exported to international and regional markets, processed, or remains on the local market. Nutritional flows across value chains and their resulting nutritional impact are poorly understood. The purpose of this study was to estimate the past, present, and future nutritional impact of the mango value chain in Côte d’Ivoire. We adapted the NUTRI-P-LOSS methodology that predicts nutritional postharvest losses across crop value chains, to assess nutritional flows in the mango value chain. Mango production quantities were estimated, and fruits at harvest, during ripening, and after drying, were analysed for macro- and micronutrients. Findings indicate that mango domestic nutritional contribution is likely to increase in the future, helping address vitamin A and C deficiencies and anaemia related-issues that remain prevalent, particularly among vulnerable groups such as children under five, pregnant teenagers and women (<i>i.e.</i> meeting requirements for vitamin C, from approximatively 60,000 people in 2000, to 1 million people in 2050). Whilst vitamin A is concentrated in dried mango, vitamin C—the fresh fruit’s primary micronutrient—is lost in drying. Therefore, increased domestic consumption of dried mango would increase vitamin A from mango but not improve the overall nutritional impact of mango on the local population (vitamins A and C, iron). Our work leads to the development of a user-friendly tool that predicts the past, present, and future nutritional impact of crop production with mango in Côte d’Ivoire as an example.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1011 - 1025"},"PeriodicalIF":4.5,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01657-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465447","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, in turn, is contributing to the exacerbation and geographical spread of conflict through conflict–food insecurity feedback loops. The primary objective of this study was to examine local variations in food security from a micro-level, household-based perspective. To this end, the impact of location-specific determinants, including rural settlements, altitude, conflict, and market distance, on household food security were assessed. This study was conducted in the Sulaymaniyah province of the Kurdistan Region of Iraq, a region characterised by armed conflict in rural areas and heterogeneous local conditions. Data were collected from 391 respondents and analysed using an ordered logit model. The Food Consumption Score (FCS) and the Household Food Insecurity and Access Scale (HFIAS) were used to assess food security. Our findings indicate that conflict exerts a detrimental effect on household food security. In contrast, households in urban and highland areas exhibit a more favourable food security status in comparison with households located in rural and lowland areas. Furthermore, improved access to the food market has a positive impact on household food security. To reduce food insecurity and decelerate the spread of conflict, it thus appears imperative that households in rural areas, particularly those in dry lowlands, be supported through direct payments, food aid, and infrastructure investments as part of conflict-sensitive and resilience-oriented development strategies to facilitate their access to food markets.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"977 - 996"},"PeriodicalIF":4.5,"publicationDate":"2026-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01647-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466292","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}

However, these shifts remain uneven, with high-income nations often demonstrating weak commitments to food security. This Australian case study draws on analyses of 102 food-related policies, 25 stakeholder interviews and 500 public surveys conducted across the states of Queensland, Victoria, and Western Australia, revealing both systemic barriers and opportunities. Policy analyses highlight the inadequacy of food security agendas across local, state, and national levels of government, characterised by a disconnect between dominant economic narratives and food security priorities. Interviews and surveys reveal a divergence between policymakers’ and the public’s perceptions of food insecurity, with public concerns remaining high regardless of gender, income, and household spending power. Three perception barriers hinder effective food security policymaking: (a) narrow conceptualisations of food security, (b) governance fragmentation, and (c) limited understanding of food systems. We argue for a three-tiered, food systems-centred and rights-based approach for food security policymaking across local, state (or regional), and national or international levels. This framework helps overcome entrenched perception barriers, catalyse more transformative policymaking, and reduce policy disparities between high- and low-income nations. If widely adopted, these policy shifts could strengthen global food security and accelerate urgently needed progress towards achieving multiple global sustainability goals.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"961 - 976"},"PeriodicalIF":4.5,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01655-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466357","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 indicators such as GDP per capita and total factor productivity exhibit inconsistent effects, highlighting structural challenges in translating growth into broad-based agricultural development.

This study examines the relationship between forest proximity and food security in rural Indigenous and mestizo households across several communities in the Colombian and Peruvian Amazon. We define ‘forest access’ as the spatial proximity of households to forests, opposed to rights-based frameworks. Using household-level panel data collected across rainy and dry seasons, we develop a multidimensional food security index covering availability, access, utilization, and stability. To address potential endogeneity in forest access, we use an instrumental variable strategy based on travel time to forest areas. Our results show significant heterogeneity between countries and communities. In La Pedrera, Colombia, Indigenous households living near less-degraded forests show higher food security, supported by traditional practices and forest biodiversity. In contrast, in Ucayali, Peru, the benefits of forest proximity are more limited and vary between Indigenous (Shipibo-Conibo) and mestizo communities, with mestizo households relying more on markets. Forest access enhances food security, but its impact is uneven across seasons and ethnic groups, reflecting the complex interactions between ecological conditions, market integration, and cultural practices. These findings highlight the importance of forest quality, local culture, and seasonal dynamics in shaping food security.

Smallholders used a range of attributes to differentiate maize seed products, indicating familiarity with most maize varieties included in the study. However, the attributes that farmers used to distinguish between maize seed products were not always those of highest value when choosing seeds for planting. Preferences for attributes differed between counties and were shaped by climate and the importance of maize in livelihoods. Women and men used and preferred similar attributes, yet their choices were informed by different underlying motivations and values. Overall, participants highly valued ‘higher yield’, ‘harvest assurance’ and ‘earliness’, reflecting diverse household uses of maize to support food security, income generation and well-being.
