With the advance of climate change and environmental changes threatening livelihoods, their impacts on migration and displacement are receiving increasing attention in research, politics, and civil society. The issue is complex and multi-dimensional, with environmental changes affecting human mobility in diverse ways. The three reports in this series thus evaluate the evidence base for policymaking, and provide entry points for responses in the field of climate change adaptation.

This first report reviews the literature’s key findings to date and provides an overview of theoretical and empirical research into the linkages between environmental stressors – including climate change – and human mobility.
