July 30, 2021 — Climate change-driven redistribution of key commercial tuna species will deliver an economic blow to the small island states of the Western and Central Pacific and threaten the sustainability of the world’s largest tuna fishery, a major international study has found.
The study combines climate science, ecological modeling and economic data to provide a comprehensive analysis of the impact of climate change on Pacific tuna stocks and on the small island states that depend on them. It is published today in Nature Sustainability.
A consortium of institutions and organizations from across the Pacific, North America and Europe contributed to the research, including the University of Wollongong, Conservation International, the Pacific Community (SPC), the Pacific Islands Forum Fisheries Agency (FFA), and the Parties to the Nauru Agreement Office (PNAO).
The 10 island states of the Western and Central Pacific—Cook Islands, Federated States of Micronesia, Kiribati, Marshall Islands, Nauru, Palau, Papua New Guinea, Solomon Islands, Tokelau and Tuvalu—are so reliant on their tuna fisheries for economic development and food security that they are considered “tuna dependent.”
