Migration and displacement are among the range of pressures on people and their communities likely to arise from the economic, social and environmental consequences of climate change. Despite fragmented data, the climate security literature has focused on the potential for climate change-induced migration to trigger social tensions and conflict within states and across borders. A human security approach seeks to ensure that people are placed at the centre of concerns about mobility and migration in response to climate change. This requires more than identifying those who are vulnerable to migration pressures. It necessitates an understanding of how migration and mobility choices are made, how vulnerabilities can be managed in ways that are participatory and responsive to local needs and circumstances, and how local, national and regional policy responses can strengthen the knowledge base and improve collaborative platforms for action.
