Climate change has significant implications for Pacific island populations, many of whom reside in coastal areas and rely on natural resources for their livelihoods and well-being. Climate change impacts may affect internal or even international migration flows as some island environments become less able to support the communities that depend on them. The linkages between climate change and migration are only beginning to gain recognition. There have been a few studies on climate change and migration conducted in the Pacific; however, the methodology used across studies has not been consistent and the studies have also not been linked with policy interventions. This report provides a synthesis of the current information available on climate change and migration in the Pacific. It also identifies information gaps in the existing knowledge base.
