Climate Mapping Campaign: Help map Eastern & Southern Africa to fight climate change!

The devastating impacts of climate change, from intense cyclones to prolonged droughts, are threatening the lives and livelihoods of millions in Eastern and Southern Africa. At HOT's Open Mapping Hub (OMH-ESA), we are dedicated to advancing open mapping solutions for community development and social impact.

That’s why we’re launching the Climate Mapping Campaign, a critical initiative to empower communities across Eastern and Southern Africa. With the power of OpenStreetMap, we aim to create vital data that will be instrumental in supporting preparedness, response, and early recovery efforts for those facing climate-related disasters.

The campaign runs from April 18th to the end of September 2024.

How it works:

Together, we will map critical infrastructure (buildings, roads) in vulnerable areas. This data helps disaster response teams plan for faster aid delivery, allocate resources to those most in need, and respond more effectively after disasters.

Our Focus:

  • Mozambique: Rebuilding after Cyclone Filipo with local communities.
  • Zambia: Mapping land use to combat drought with government agencies.
  • Kenya: We partnering CIAT for climate-smart agriculture solutions.
