Some areas worldwide are becoming less habitable due to increasingly extreme climate-related hazards. Other areas could become more habitable, allowing new economic activities such as agriculture or tourism. International processes, particularly those on migration and displacement, climate change and disaster risk reduction, increasingly refer to the links between climate change and human mobility.

However, these links are not always grounded in evidence, and this increased attention has not led to the coordinated, significant policy or legislative change that is required. We need to consider the current evidence base on the complex relationships between climate change and human mobility, to support the development of an informed global discourse on links between climate, displacement and migration.
