This Paper, co-authored by Changing Ocean Research Unit members Juliano Palacios-Abrantes, Gabriel Reygondeau, and CORU leader Dr. William Cheung, examines the impact of climate change on seafood micronutrient supply from wild-capture fisheries in Southeast Asia and Pacific Island countries. The researchers combined a dynamic bioclimate envelope model with reconstructed catch data to project changes in maximum catch potential and micronutrient availability under different climate change scenarios. They found that climate change will significantly decrease catch potential and micronutrient availability in all regions, especially under high emission scenarios. They also concluded that most of the examined micronutrients from wild-capture fisheries will not meet the projected demand for most micronutrients, even under strong climate change mitigation strategies, highlighting the need for effective fisheries management and diversifying food sources to ensure nutritional security.
