Projected internal climate migrants in Sub-Saharan Africa 2050, by region

According to the original source, "the three climate migration scenarios are defined as:
Pessimistic: reference scenario, with high global greenhouse gas emissions and an unequal development pathway;
More inclusive development: equally high emissions, but a more equal development pathway.
More climate-friendly: lower emissions, combined with an unequal development pathway."

Climate-driven migration refers to "migration that can be attributed largely to the slow-onset impacts of climate change on livelihoods owing to shifts in water availability and crop productivity, or to factors such as sea-level rise or storm surge".

Figures only include internal displacement. They do not consider cross-border migration, or shorter-term mobility (such as seasonal or cyclical migration).
