Pacific Island countries are demonstrably vulnerable to the risks of climate change, disasters and conflict. This article outlines the conceptual links between these risks, briefly describes how each of the risks operates in the Pacific Islands, and goes on to demonstrate the interaction of climate change, disasters and potential for conflict in the Pacific Islands, by applying a new conceptual framework to some illustrative case studies. The case studies include relocation after the Gizo earthquake, 'environmental refugees' from sea level rise, and aggravation of the social issues of urbanization and unemployed youth by climate change. Fortunately, none of these cases has yet crossed the threshold into violent conflict, even though relocation of an affected community onto someone else's land is a particularly sensitive issue in the Pacific Islands.
