Human-induced environmental change puts many of the world’s largest aquatic food producers at risk, especially in Asia, Latin America and Africa. This is the main finding of a new study by the Blue Food Assessment which was published in Nature Sustainability. The study shows that more than 90 per cent of global “blue” food production, in both capture fisheries and aquaculture, faces substantial risks from environmental change, with several leading countries in Asia and the United States set to face the greatest threats to production. Environmental changeThe authors behind the new paper produced the first-ever global analysis of environmental stressors impacting the production quantity and safety of blue foods around the world, ranking countries according to their exposure to key stressors for the first time. A total of 17 stressors were surveyed, including harmful algal blooms, sea level rise, changing temperatures, pesticide exposure, and more.
