Mapping of the August 2020 Douala Flood Impact and Its Consequences for Urban Planning and Investments
Context and objectives
Following the August 2020 flooding in Douala, which caused widespread damages and displaced over 5,000 people, the Government of Cameroon and the municipal authorities of Douala are receiving technical support to assess the flooding’s impact, and to build their capacities to use low-cost, collaborative, and open-data collection approaches for Disaster Risk Management (DRM).
Main activities and results
- Component 1-Flood impact mapping - This component provides for cost-effective flood-mapping by using gender-inclusive participatory and open data approaches that engage women from institutional partners as well as female mappers trained under the ACP-EU NDRR Integrating Climate and Disaster Risk Considerations into Development Planning in Cameroon project. Models of the August 2020 disaster event will be taken from previous flood-modelling experiences initiatives undertaken in the localities of Ngaoundéré and Yaoundé. These models will be linked to ongoing World Bank project investments under the Cameroon Resilient and Inclusive Cities Project (PDVIR) and the preparation of the Douala Urban Mobility Project (PMUD) to support the CUD in its contingency and urban planning.
- Component 2-Capacity building in integrating flood risk modelling into urban planning - This component builds on the results and knowledge developed through the course of the ACP-EU NDRR Integrating Climate and Disaster Risk Considerations into Development Planning in Cameroon. This includes the developed flood-risk models for Yaoundé and Ngaoundéré and their integration into urban planning of the municipalities. In addition, the component will be building on the capacity building and technical assistance from which Douala has benefited as part of the World Bank’s City Resilience Program.
The Douala Municipality was provided with technical support to assess the flood impact in Douala through capacity building on the use of low-cost, collaborative, and open data collection approaches for DRM. New modelling activities are also being applied beyond the single event of August 2020 to produce flood models with a return period and a model on flooding caused by sea-level rise. Additional hydrological and meteorological data is being collected to inform these models and develop a flood hazard model for sea-level rise.
Partnerships and coordination
This project is being implemented by the World Bank’s Africa Urban Resilience team in collaboration with the Municipality of Douala, the Ministry of Housing and Urban Development, the Ministry for the Economy and Regional Planning (MINEPAT), the Civil Protection Directorate under the Ministry for Territorial Administration (MINAT), the National Fire Brigade Corps (CNSP), and the Ministry of Health (MINSANTE).
