This report provides an overview of how human mobility in the context of climate change (HMCCC) fits into the policy landscape of nine island and archipelagic countries: Anguilla, Antigua & Barbuda, Dominica, and St. Lucia in the Eastern Caribbean; Fiji, Kiribati, Tuvalu, and Vanuatu in the South Pacific; and the Philippines in the Western Pacific. All of these nations are heavily affected by climate impacts like sea level rise, ocean acidification, tropical cyclones and hydrological extremes. The report provides insights gained from 94 expert interviews and regional literature reviews and shows the strength of regional approaches for improving migrants’ rights and for increasing climate resilience. The findings are relevant to other island nations that face similar challenges and need to build capacity for future climate-related mobility dynamics. Moreover, they highlight the necessity of building a coherent multilateral framework on HMCCC to accommodate and support people who may have to move in the future. The research for this study was conducted by the Potsdam Institute for Climate Impact Research (PIK) in collaboration with local Researchers as part of the Global Programme on Human Mobility in the Context of Climate Change, funded by the German Federal Ministry for Economic Cooperation and Development (BMZ) and implemented by GIZ.
