This policy report focuses on climate change and international movement from Pacific island countries (PICs), which face a specific set of challenges in that respect. In the shorter term, climate change is to continue exacerbating preexisting difficulties, making life on the islands increasingly challenging. In the longer term, such countries are at risk of becoming entirely uninhabitable. As a result of rising pressures at home, human mobility in PICs is already being affected in complex and intersecting ways. Some of this movement is and will be across international borders, most of which remains unrecognized and unprotected as of today. In view of this, the present report intends to shed some light on the issues raised by this topic and suggests a series of recommendations on how to possibly address them.
