- The ocean is integral to the production of nutrient-rich marine foods, however, shifts in productive fish species due to climate change represent a serious threat to food security. - Socioeconomic disparities within global food systems reinforce the case for food sovereignty, social-ecological resilience and the importance of harnessing indigenous knowledge to reframe the rights of local resource users. - Preserving and supporting diverse local food systems to thrive through locally relevant and adaptive fisheries management will become increasingly important. - The future of seafood contributions to global food supply will depend on effective, rapid, and sustained mitigation and adaptation actions and a combination of ecological, economic, policy and technological influences.
