Socialprotection(SP),which includes socialassistance,socialinsurance,andlabormarketinterventions,1 is a powerful lever forachieving food and nutrition security (FNS). In thenear term, SP can protect diets and livelihoods fromshocks,which often drive food insecurity andmalnutrition.In the longer term,SP can shapeincentives,jobs,and services along food valuechains.Achieving FNS cannot be done throughimprovements in food availability or income alone; The entry point for the World Bank’s work on BlueSP was the challenge of managing fisheries forsustainability (Bladon et al. 2022; 2025). Given theyentail harvesting from wild, common-pool resources,fisheries present unique challenges for balancingshort-term FNS objectives with sustainable supply.Widespread failure to adequately address thesechallenges has resulted in global fish-stock declines.At the same time, demand for aquatic foods is on therise (FAO 2024). In small-scale fisheries (SSF), which are Although work to date on Blue SP has thereforefocused on leveraging SP to promote sustainable SSF,the Blue SP approach can be adapted and expanded toother components of aquatic food systems to deliverFNS benefits. While SSF remain central to this brief, The World Bank has been supporting countries inadopting an intersectoral approach to protectingpeople,aquaticecosystems,andaquaticfoods,referred to as Blue Social Protection(BlueSP).Aquatic foods — animals, plants, and microorgan-ismsproducedthroughcapturefisheriesand aquaculture — have considerable The Role of Aquatic Foods in Food and Nutrition Security Fisheries and aquaculture already feed billions ofpeople globally, yet mounting evidence suggeststhese sectors could play an even more significant rolein eradicating hunger and malnutrition (Leape et al.2023; Crona et al. 2023). Aquatic foods supply 40% ofthe world’s population with at least 20% of per-capitaanimal protein (FAO 2024). They are also an importantsource of essential fatty acids and micronutrients, al. 2022), unless thos
