What We Do

Community Mapping for Flood Resilience and Development

Ramani Huria is a community-based mapping project that began in Dar es Salaam, Tanzania, training university students and local community members to create highly accurate maps of the most flood-prone areas of the city. As the maps have taken shape – their benefits have multiplied and their potential magnified, now serving as foundational tools for development within all socio-economic spheres beyond flood resilience.

How We Do It



Ramani Huria trains university students and local community members to create highly accurate maps of their city using a wide variety of methods for data collection.


To generate content from data collected by community mappers, we collaborate with OpenStreetMap – a web platform working to create a free and open map of the entire world.

Modelling Risk

Using InaSAFE, a free software that produces realistic natural hazard impact scenarios, our data helps to devise better planning, preparedness and response for disaster.


All data collected by the Ramani is free and accessible for anyone to use on OpenStreetMap and right here on our website.
