World Bank, Washington, DC. Photo credits: Page 3 and 4: Joseph CatanzanoPage 11: Hanson Lu, Flickr Images This brief proposes using an intersectoralapproach to social protection in aquatic foodsystems as a means to improve food andnutrition security (FNS).It highlights thecritical role of aquatic foods in global FNSand describes how Blue Social Protection canhelp maintain and enhance this, with aparticular focus on small-scale fisheries. Thebrief also provides recommendations forpolicy makers and practitioners interested inmaximizing FNS through Blue SocialProtection. What is Blue Social Protection? 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;it requires affordable access to safe and nutritiousfood, especially for poor and nutrition-ally vulnerablepopulations. SP can improve nutrition through twocomplementarypathways:by directly improvingdietaryintake and nutrient adequacy;and byaddressing underlying causes of malnutrition such ashouseholdfood insecurity,caregiving practices,and access to services (Alderman 2015; Gentilini2022).
