The Ramani Zetu Sauti Zetu project is built on the foundation of the Ramani Huria project, which set a precedent for community-based mapping to enhance flood resilience in Dar es Salaam. Ramani Huria empowered communities, local government, and emergency responders to create and utilize open locally verified spatial data to identify flood-prone areas, map drainage infrastucture and enhance disaster preparedness plans and response.

The project carries this legacy forward while expanding its scope both geographically and strategically. Whereas Ramani Huria focused on mapping and community engagement, the new initiative introduces critical elements that enable communities to act on data. This includes supporting the development of community-based early warning systems such as Sirens, repairing drains, designing localized disaster preparedness plans, stronger coordination with government and humanitarian actors, and awareness campaigns to drive behavior change.
