CBFEWS is an integrated system of tools and plans managed by and for communities. It provides near real-time early warnings when rising flood waters are detected. The warning information is transmitted to caretakers who disseminate the information to the rest of the community, government line agencies, and stakeholders. Although the detection of flood risk and its communication to vulnerable communities are driven by technology, the primary functioning of the CBFEWS lies in a people-centred approach to flood response.
