Mapping refugees’ and IDPs’ exposure to climate-related hazards

This brief seeks to fill a gap in knowledge on the extent to which refugees and Internally Displaced People (IDPs) are vulnerable to specific climate-related hazards, and is one of a few pieces of publicly available research providing such large-scale data.

It is one of a few pieces of publicly available research providing large-scale data on the number of refugees and IPDs living in climate-related hazard-prone areas, disaggregaded by hazard. Its primary focus is on capturing the exposure of conflict-generated forcibly displaced people; however, it was not always possible to capture the causes of displacement for IDPs, meaning that climate-induced IDPs were in some cases also captured. However, these figures on climate-related displacement are in the minority: of the 75.9 million IDPs in existence at the end of 2023, the vast majority (68.3 million) were displaced by conflict and violence, and 7.7 million by climate-related hazards.
