Migration, climate change and the environment

Environmental factors have long had an impact on global migration flows. Although there is limited reliable data on the subject, the scale of such flows, both internal and cross-border, is expected to rise significantly over the next decades as a result of climate change. This Policy Brief presents key information and analysis on the interplay between migration, climate change and the environment. It is designed as a general introduction to the topic and presentation of the perspective and involvement of the International Organization for Migration (IOM) in this field.
