International Organization for Migration - About Migration - Topic of the Month

Migration and Climate Change

Environmental factors have long had an impact on global migration flows, as people have historically left places with harsh or deteriorating conditions. However, the scale of such flows, both internal and cross-border, is expected to rise as a result of accelerated climate change, with unprecedented impacts on lives and livelihoods. Such migration can have positive and negative effects on both the local coping capacity and the environment in areas from which these migrants originate, as well as in their temporary or permanent destinations.

In the cross-cutting area of migration, climate change and environmental degradation, IOM addresses linkages between the environment and climate change on the one hand, and human settlement and population movement on the other from a human mobility perspective.
