Catches are used for direct human consumption, to produce fishmeal and fish oil for animal feeds and to manufacture value-added products. SPFS constitute a valuable source of micronutrients, fatty acids and protein that could help alleviate malnutrition and food insecurity in sub-Saharan Africa. Considering this context, this study aimed to identify and prioritise recommendations concerning SPFS use. Preliminary recommendations came from interviews (<i>n</i> = 122) and focus groups (<i>n</i> = 642) with women and men. Representative stakeholders from Gambia, Ghana, Malawi, Mauritania, Republic of Congo, Senegal, Sierra Leone and Uganda engaged in a Delphi study. Responses were received from 150 to 115 participants in Rounds 1 and 2, respectively. Priority recommendations (Round 2 mean rating &gt; 8) included: environmental audits of fishmeal plants, promote health and safety at work, assess health risks, eliminate pollution, locate factories away from residential areas, promote alternative feed ingredients, farmer training and research programmes, enhanced governance, demand assessment, price controls on fish for feed, regular assessment of key fish stocks, assess and monitor fish affordability, consumption and importance in food and nutrition security, promote better handling to avoid food waste, regulate capacity of fishmeal sector. Comprehensive and effective implementation of priority recommendations could ensure that SPFS use can contribute to food and nutrition security and help provide sustainable and healthy diets across sub-Saharan Africa.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 6","pages":"1459 - 1477"},"PeriodicalIF":5.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821319","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, the synergistic effects of different types of technologies within ISFM remain inadequately understood. This study analyzes individual and combined impacts of adopting ISFM practices, specifically inorganic fertilizer and Soil and Water Conservation (SWC) practices, on net crop value and per capita food consumption expenditure. Using primary data collected from 781 plots in eastern Ethiopia, the study employs Multinomial Endogenous Switching Regression (MESR) to identify those factors associated with the adoption of these practices and evaluate their impacts on households’ welfare, while accounting for both observable and unobservable biases. The average treatment effects of adopting inorganic fertilizer and SWC practices either separately or in combination show that these practices result in improved net crop value and per capita food consumption expenditure. Interestingly, the combined impact of inorganic fertilizer and SWC practices on net crop value and food consumption expenditure is more than double when compared to adopting these practices separately. Moreover, our finding shows that the age and educational level of the household, irrigation use, and cultivated area are positively and significantly associated with the likelihood of adopting the combination of inorganic fertilizer and SWC practices. Therefore, encouraging and supporting farmers to adopt a combination of inorganic fertilizer and SWC practices will result in significant welfare gains.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 6","pages":"1445 - 1457"},"PeriodicalIF":5.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821317","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}

Some of the largest impacts are expected in food-importing African countries. This includes Nigeria, where a combination of increasing population, urbanization, and declining domestic production increased households’ exposure to global price shocks. To understand how food demand responds to price shocks, we estimate household-level demand elasticities for selected food categories using the Exact Affine Stone Index (EASI) demand model. We simulate the effect of increasing grain and edible oil prices on demand by households across several food groups and items. Our results vary across regional and income groups and often differ because grains and edible oils represent different proportions of the respective sub-national budget shares. We find that, given their low price elasticity, a shock to the price of edible oils generally leads to changes to the household budget share. We also find that the war is expected to have the highest impact on non-grain starches and vegetable proteins, which had the highest own-price elasticities. Nevertheless, given that palm and groundnut oil are the dominant edible oils in Nigeria, the effects of the war depend on the elasticity of substitution between sunflower and these two oils on the global markets, as well as between edible oils and other foods. One policy implication of the study is the need for targeted food and nutrition interventions in response to crises or global price shocks, given the substantial sub-national variation in observed food budget shares, and in the effects of price shocks.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 6","pages":"1419 - 1443"},"PeriodicalIF":5.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821318","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}

The importance of trees has been recognized by humanity since ancient times. However, changing climate and genetic erosion are causing rapid loss of diversity indicating an urgent need to conserve and maintain genetic resources for food security. India is the second largest producer of fruits and vegetables in the world. An analysis of the status of diversity, distribution, and conservation of fruit genetic resources (FGR) in India was carried out to determine the opportunities and challenges in the management of fruit germplasm for sustainable food security. The objectives of this article include (i) tracing fruit crop diversity and distribution in India (ii) discussing the potential of wild relatives of indigenous fruit crops; (iii) reviewing conservation strategies in the Indian and global context (iv) current conservation status of fruit crops (iv) analysing constraints in germplasm conservation and utilization; (v) and proposing new ways to safeguard FGR. Methods employed include database retrieval, literature review, and communication with key informants. India is home to several fruit species of global importance including mango, banana, and some citrus, and holds approximately 148 crop wild relatives (CWR) of fruits. The first gene sanctuary of wild citrus species was established in the Garo Hills of Meghalaya and efforts are being made to also establish gene sanctuaries for &lt;i&gt;Musa&lt;/i&gt; species and mango. Over 13,000 accessions of fruit crops are conserved in field gene banks of seven regional stations of the Indian Council for Agricultural Research- National Bureau of Plant Genetic Resources (ICAR-NBPGR) and 10 National Active Germplasm Sites working under the National Agricultural Research System&lt;i&gt;.&lt;/i&gt; The ICAR-NBPGR maintains some 4,000 accessions in its cryobank as seed, embryo, and embryonic axes as explants; some 800 accessions in the in vitro repository; and about 100 accessions in the in vitro base gene bank belonging to tropical, temperate, and minor fruits. By contrast to field crops, the conservation of fruit crops poses unique challenges; this is because these collections comprise only 6% of the total accessions that are maintained in ex situ collections worldwide. Basic research is needed to develop robust medium- and long-term conservation protocols for fruit crops and their wild relatives. This especially concerns challenging recalcitrant seeded species such as &lt;i&gt;Artocarpus&lt;/i&gt; spp., &lt;i&gt;Litchi chinensis&lt;/i&gt;, &lt;i&gt;Mangifera&lt;/i&gt; spp., &lt;i&gt;Syzygium&lt;/i&gt; spp., &lt;i&gt;Garcinia&lt;/i&gt; spp., among many others.

However, its impact on farmers’ nutrition and informal sharing arrangements and associated solidarity within African farming communities remains uncertain. To analyse these trade-offs, we study the growing commercialization of African indigenous vegetables (AIV) in Kenya. These vegetables are an essential component of local diets in rural areas but also of informal sharing arrangements that provide access to food outside of markets. This article combines quantitative data from a 2016–2022 panel survey of farmers with qualitative data from focus group discussions. Results based on household fixed-effects models show a significant increase in households’ non-food expenditures due to selling AIV. The results suggest that selling AIV did not negatively affect nutrition outcomes but did not improve them either. Informal AIV sharing between households decreased further with growing market participation. Panel data models indicate, however, inconsistent and insignificant changes in associated solidarity indicators. We attribute this to the multiple and sometimes opposing effects of market-oriented farming on solidarity, as revealed by focus group discussions. While some farmers perceive reduced solidarity due to less informal AIV sharing, others perceived this traditional solidarity to be partially forced. Other forms of social interaction have also emerged, such as cooperatives and more intensive knowledge sharing. Despite concerns about the loss of informal sharing and community solidarity and limited improvements in nutrition outcomes, the tangible income gains generated by selling AIV are likely to foster further growth in the AIV sector.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 6","pages":"1363 - 1379"},"PeriodicalIF":5.6,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12571-024-01480-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142821456","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}

It also highlights the central role of city governance in SFT. However, large gaps exist in understanding of the regulatory arena, that constrains policy discussion, hinders traders, and inhibits access, affordability, and availability of safe street food. This paper examines implications of SFT regulations on FS and urban livelihoods. We focus on a cross-section of 260 street food enterprises (SFEs) in urban Kumasi, Ghana, and explore interactions of compliance with SFT regulations, adoption of improved practices, enterprise performance and their links to FS in UFSs. We find that though vendors are generally aware and willing to invest in improved practices, compliance levels with regulations are below average due mainly to insufficient, inconsequential, and uneven regulatory enforcement. We also find that compliance costs are high whilst detected non-compliance neither bears sufficient legal nor financial consequences. Lastly, compliance requirements negatively impact urban FS such that, annual compliance costs inhibit the supply of over 103,000 food servings from the UFS whilst compliance-induced innovations siphon out over half a million food servings from it annually. The later also increases prices of street-vended food by about 6%. From a modern urban food policy perspective, our findings suggest urban food policy and city management efforts could enhance the FS role of SFT, if they prioritize promoting improved practices, simplifying regulations, and assisting vendors in compliance.</p></div>","PeriodicalId":567,"journal":{"name":"Food Security","volume":"16 5","pages":"1081 - 1098"},"PeriodicalIF":5.6,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142251999","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}
