To provide a data set that allows users to understand how climate change impacts on water availability, crop productivity, and pasturelands (where no cropping occurs), coupled with sea-level rise, storm surge and flooding, may affect the future population distribution and climate-related internal migration in West Africa and the Lake Victoria Basin.

To provide a data set that allows users to understand how slow-onset climate change impacts on water availability and crop productivity, coupled with sea-level rise and storm surge, may affect the future population distribution and climate-related internal migration in low to middle income countries.
