The objective is to predict data-driven levels of household food insecurity by considering the effect of space, time, and statistically significant factors. This study analyzed Ethiopian socio-economic household panel data for the years 2012, 2014, and 2016, comprising a sample of 3,835 households. Predictions were made using transductive deep learning algorithms to capture spatial and temporal dynamics, with 75% of the data allocated for training and 25% for testing. The results from training the temporal graph neural network model (T-GCN) with 4- and 2-layer architectures using 64 and 32 hidden units indicated that the 4-layer T-GCN with 64 hidden units predicted household food insecurity levels with greater accuracy. The prediction of the test data using the T-GCN model with 64 hidden units and 4 layers (T-GCN(64,4)) achieved an accuracy of 75.81%, outperforming baseline models in capturing spatial dependency with GCN (69.72%) and temporal correlation with RNN (54.66%). Additionally, the T-GCN(64,4) effectively predicted household food insecurity across most parts of the country, with an accuracy of 79.77% for 2014 and 72.43% for 2016. The higher stable prediction accuracy of the T-GCN in all prediction horizons demonstrated its superior performance and indicated the effectiveness of the data-driven approach in leveling severity and determining the related factors of household food insecurity. Therefore, efforts should be focused on urbanization, education, employment, non-agricultural business, water and sanitation, soil protection, and farming practices to reduce the severity of food insecurity by addressing dependency ratios, shocks, land ownership, and early marriage.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 4","pages":"867 - 883"},"PeriodicalIF":4.5,"publicationDate":"2026-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-025-01638-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466293","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}

While food systems operate across scales from local to global, processes of change are rooted in local and regional contexts. In Sweden, the interest in food resilience has increased over the last decade. The aim of this study is to explore the state of Swedish municipalities’ work on food system planning in the context of resilient local food systems and food contingency planning. A survey was conducted, with responses received from 73% of Sweden’s 290 municipalities. The data were analysed using an established categorisation of municipalities to enable comparison across categorises. Main results show that the majority of municipalities support work to develop local food systems and that there is a local political will to do so. However, political will was reported to be weaker in both very sparsely populated rural municipalities and large city municipalities. The main barriers identified were a lack of clear regulations, insufficient national-level support, and limited resources (funding/staff), particularly regarding how to work with food contingency planning. A lack of resources was more frequently reported by rural municipalities compared to others, potentially indicating a lower capacity to respond to crises in these municipalities. Additionally, few municipalities had developed a local food strategy. Overall, the study highlights that municipalities have been engaged with local food systems for a longer time, while work on food contingency planning has recently begun for the majority.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 2","pages":"423 - 441"},"PeriodicalIF":6.2,"publicationDate":"2026-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-025-01642-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147560447","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}

With the population projected to reach 2.5 billion by 2050, food demand is expected to rise by 60 to 70% compared with 2020 levels. Meeting this challenge may require locally driven scientific innovation; however, Africa continues to underproduce and underutilise doctoral-level scientists in food security-related fields. At present, fewer than 1,500 PhDs are awarded annually in agricultural and related sciences across the continent, far below the estimated requirement of 8,000 per year to meet projected needs by 2050. This study examines the current state of doctoral training in Africa, the quantitative gap between the supply of and demand for food security expertise, and the institutional, policy, and funding constraints that limit research capacity. Drawing on comparative data and case studies, it argues that Africa must train at least 100,000 new PhD scientists in food security-related disciplines by 2050. Recommended priorities include raising investment in research and development to at least 1% of gross domestic product, strengthening regional research infrastructure, expanding partnerships between universities and industry, and implementing retention policies to curb the loss of highly skilled scientists. The future of food security in Africa will depend not only on producing more food but also on generating more knowledge, with doctoral-trained scientists playing a central role in this transformation.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"18 3","pages":"699 - 703"},"PeriodicalIF":6.2,"publicationDate":"2026-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147959177","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}

Ninety-six settlements were allocated 1:1 to intervention (1337 women) and control arm (1368 women).

In its final year, the intervention increased the number of harvested vegetable species by 4.3 and total crop species by 6.4, more than double over control. We also saw sizable changes in production practices. Impacts were present in all seasons, consistent across gradients of wealth and education and maintained up to 2.5 years post-intervention when they seemed to spill over to controls.

We also observe dry conditions to determine a larger decrease in food diversity in individuals with none or low educational attainment.

In the present study, we used optimization models to first demonstrate the potential of reducing GHGs by diversifying global crop production quantities, and secondly, the impact of increased cultivation of undervalued crops on the economic and nutritional value of crop production. We observed that a select number of undervalued crops can drive GHG reduction, yet in certain cases, major crops were more favoured to reduce GHGs.
