Water Risks


Areas that will be affected by significant flooding by 2050

Data Interpretation

Climate related increases in river flooding will be an important driver of climate mobility across Africa. Floods accounted for 80% of all disasters in Africa from 2000 to 2020.

Data Modelling

Model considers the likelihood of human mobility into areas that are projected to experience increasing flood risks. The flood impact model is at 500m resolution, and is based on projected flood depth. Measured in terms of the reduction in population potential for every 5km2. Projections of future population distributions based on flood risk are provided by the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP).
