Climate change is impacting lives and livelihoods across the African continent, through increasing temperatures, shifting rainfall patterns and an increase in the frequency and intensity of extreme weather events, particularly droughts and floods. This snapshot examines environmental drivers of international mobility and their interactions with other migration drivers in East and the Horn of Africa. The aim is to provide national and regional policy actors with some empirical data on the links between climate change and international mobility, to inform discussions on future activities and policy directions.
