Displacement & Safe Migration

dsm_icon

Conflict, persecution, violence, and natural disasters have caused a record 100 million people worldwide to be displaced (UNHCR May 2022). Humanitarian organizations and governments require accurate geospatial data to locate and understand the needs of displaced communities, identify potential risks, enable better coordination and resource allocation, and ensure that assistance reaches those who need it most. Open mapping helps us co-develop understanding together, which enables humanitarian, development, and community organizations to take more informed and locally appropriate action.
