Terms of Reference (ToR) for Individual Consultancy Services for the Installation of Community-Based Early Warning System (CBEWS) under the Ramani Zetu, Sauti Zetu Project in Dar es Salaam 

Introduction 

OpenMap Development Tanzania is currently implementing the Ramani Zetu, Sauti Zetu project, an initiative aimed at strengthening flood resilience through community-driven data collection, participatory mapping, and inclusive planning processes. Recognizing the increasing risks posed by flooding in vulnerable communities, the project places local knowledge and engagement at the centre of disaster preparedness and response. 

As part of this effort, the project focuses on the design, development, and installation of a cost-effective Early Warning System (EWS) tailored to local environmental conditions and community practices identified during mapping and planning phases. This initiative seeks to bridge critical gaps in timely flood information and response by ensuring that communities can anticipate, prepare for, and act swiftly in the face of flood risks. 

By combining low-cost technology with strong community participation, the Early Warning System aims to enhance local preparedness, reduce vulnerability, and support timely early action. Ultimately, the project contributes to building more resilient communities that are better equipped to respond to and recover from flood events.
