Frankenberger","doi":"10.1007/s12571-026-01671-8","DOIUrl":"10.1007/s12571-026-01671-8","url":null,"abstract":"<div><p>From 2017 to 2020, Sahelian zones of Burkina Faso and Niger were rocked by a series of simultaneous climate, conflict, economic, demographic and health shocks. The crisis came to a head with COVID-19 pandemic lockdowns and market closures in the midst of flooding and an upsurge in terrorism. Meanwhile, in 2015 the USAID-funded “Resilience in the Sahel-Enhanced” (RISE) project had rolled out a series of interventions designed to strengthen households’ resilience to shocks through bolstering their absorptive, adaptive and transformative capacities. This paper documents trends in these capacities and household resilience over the crisis period. It then investigates the impact of RISE interventions on them. It finds that the majority of households were not resilient and key capacities stagnated or declined, including asset ownership, informal safety nets, and access to markets. The prevalence of severe food insecurity rose from 32 to near 50 percent, and incidences of illness and deaths rose precipitously, signaling a humanitarian crisis. The crisis rose to such proportions that many of the RISE project interventions were disrupted—they were not resilient to the shocks themselves. The impact evaluation finds that, overall, the project had a positive impact on households’ resilience and some resilience capacities. However, its impact was below potential. The interventions most vulnerable to flooding, terrorist attacks, and COVID-19 restrictions did not show positive impacts. Further, despite the project’s approach of integrating humanitarian and development assistance, households’ access to food aid plummeted as shocks escalated. Yet food aid had strong, positive impacts on the resilience of households that did have access to it. In navigating the Humanitarian-Development Nexus in resilience programming, this study points to the key importance of (1) paying attention to the resilience and sustainability-of-impact of interventions themselves; and (2) strategic planning in advance to pivot to humanitarian assistance when shocks rise to crisis proportions.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1179 - 1210"},"PeriodicalIF":4.5,"publicationDate":"2026-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466421","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}

This study examines dietary diversity and food security and evaluates the impact of development projects in low and middle-income contexts. We use primary data collected from development projects implemented in 24 countries. To control for heterogeneous impacts of each project-related investment, we estimate binary treatment random coefficient models among treatment (participants) relative to comparison (non-participants) households. Treatment households have statistically significant increase in dietary diversity, albeit small in terms of magnitude (0.04 additional food groups). They experience a significantly larger reduction in food insecurity (a decrease of 8.1%). Results show substantial variation in the effectiveness of development projects in improving household dietary diversity and food security, with differences in the direction and magnitude of effects across countries, regions, and types of interventions. Projects implemented in lower-income and non-fragile contexts are effective in enhancing dietary diversity and food security. Gender and age are important factors in influencing dietary diversity and food security outcomes. Female-headed and older-headed households tend to exhibit lower dietary diversity and higher food insecurity, reflecting underlying structural disadvantages rather than differential project effectiveness. Findings suggest that interventions enhancing income generation, market access, and agricultural extension services are particularly effective in improving dietary diversity and food security. In contrast, resilience-building projects in fragile contexts did not yield statistically significant improvements, underscoring the importance of context specificity in determining project effectiveness. Tailoring project design to gender and age dynamics is essential to ensure equitable outcomes.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1161 - 1178"},"PeriodicalIF":4.5,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148465893","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}

This study quantifies the buffer value of trade by comparing observed conditions of global integration with a counterfactual restricted-trade world (half trade volume). Using a global market equilibrium model of agriculture combined with a novel randomized yield-shock framework, we evaluate how production volatility translates into volatility in consumer food prices and farm incomes across global regions in 1991–2020. Results show that trade substantially dampens volatility transmission. In the United States, year-on-year volatility in farm income declines nearly threefold under open trade (from 12.1 to 3.9), while the standard deviation of consumer food price volatility falls by more than half (from 9.1 to 4.3). Globally, the volatility multiplier ratio (the extent to which production shocks amplify consumer price volatility) drops from 4 to 6 in restricted trade to just 1–2 under open markets. These findings highlight the risk-sharing role of trade: while trade barriers may protect producers in the short run, they amplify vulnerability to local shocks in the long run. Strengthening international market integration, alongside domestic investments in resilience, remains essential for managing volatility in an era of increasing uncertainty.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1133 - 1159"},"PeriodicalIF":4.5,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01662-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466594","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 Household, Income and Labour Dynamics Australia (HILDA) survey is a large, population representative survey of Australian households that has been implemented annually since 2001. In 2020 the eight item self-assessed Food Insecurity Experience Scale (FIES) instrument which documents the depth of the lived experience of food insecurity was introduced to the survey. This paper describes the prevalence and correlates of each item of the food insecurity experience amongst the Australian adult population. Overall, 14% of the population reported at least one of the eight items representing an experience of food insecurity, ranging from 9% reporting any one item, to 2% reporting either seven or eight items. Estimates ranged from 3% who reported running out of food to 9% who reported eating only a few kinds of food. Of concern is that 7 to 8% of Australian adults reported experiencing ‘hidden hunger’, that is, being unable to eat healthy food and restricting food intake due to a lack of resources for food. Age, marital status, renting, low income, smoking and health conditions were key correlates of the number of food insecurity items reported. As food insecurity is an indicator of economic and social disadvantage, inclusion of eight items in the 2020 HILDA survey— rather than the usual single item — provides a deeper understanding of the causes and consequences of food insecurity in Australia for the first time in a population representative survey commissioned by the government. This social view on food insecurity suggests that cross-government policies are needed to ameliorate the problem including those to impact income and employment, social protection, housing, and cost-of-living.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"1089 - 1107"},"PeriodicalIF":4.5,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466360","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}

This study aimed to contribute to the broader discussion on how sustainable agriculture can enhance food security and economic stability of smallholder farmers in Ethiopia. A simple random selection method was used to select 382 maize growers for the study, with a focus on maize producers in the Bunno Bedelle Zone of Ethiopia, which is dominated by maize producers. Qualitative and quantitative data were collected, and the results analyzed using inferential statistics and econometric analysis. The Average Treatment Effect Value on Treated (ATT) indicated that adopting intercropping, crop rotation, soil and water conservation, organic fertiliser, and a combination of these SAPs increased the Food Consumption Score (FCS) by 454.6, 336.0, 316.8, 385.1, and 415.1 kilocalories, respectively. Compared to non-adopters, the use of SAPs raised the Household Dietary Diversity Score (HDDS) by 1.87, 2.44, 2.29, 4.75, and 2.47 units, respectively. When compared to non-adopters, SAP use decreased the Household Food Insecurity Scale (HFIES) by 0.93, 0.66, 0.83, 0.96, and 0.08 units. Additionally, compared to SAP adopters, the Average Treatment Effect (ATU) value based on multinomial endogenous switching regression revealed that SAP non-adopters had lower values of FCS and HDDS. In contrast, farmers that did not use SAPs had a higher HFIES than users. We conclude that the food security of smallholder maize farmers in Bunno Bedelle, Ethiopia improves when they utilise SAPs. Thus, in addition to enhancing maize production resilience and productivity, support to SAPs is crucial for resolving Ethiopia’s food security challenges.</p>\u0000 </div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 3","pages":"741 - 756"},"PeriodicalIF":6.2,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-026-01658-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147959172","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}
