Supplementary notes

According to the 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 includes internal displacement. It does not consider cross-border migration, or shorter-term mobility (such as seasonal or cyclical migration).

More than *** million people worldwide may be internally displaced by 2050, due to slow-onset impacts of climate change. This is based on a pessimistic scenario of high greenhouse gases emissions and unequal development. In a more climate-friendly scenario, this figure would still add up to some *** million climate migrants, while a more inclusive development would lead to roughly ** million migrants. In all three scenarios, Sub-Saharan Africa would see the largest number of displacements resulting from shifts in water availability, crop productivity, and sea level rise within the six regions evaluated.
