The Gambia Integrated Urban and Coastal Resilience Technical Assistance Program

Context and Objectives

The Gambia’s unique geography results in it being particularly exposed to natural disasters and climate change impacts. The country is susceptible to flooding, saltwater intrusion, and erosion which are aggravated by drought, windstorms, coastal storms, and extreme precipitation during the rainy season. 

In this context, the challenges and needs for urban and coastal resilience in the Gambia are vast. Urban population grew at 4.5 percent per year during 2000-2017.

Previous ACP-EU NDRR support in Gambia in 2013-15 provided technical assistance to study and catalogue existing risk information and support the National Disaster Management Agency (NDMA) to manage this data. Building on this assistance, and considering the broader risk management challenges outlined above, the Government requested further support to update and enhance this risk analysis to better understand where disaster and climate risk is concentrated in Greater Banjul and along the 80 km coastline of the Gambia.

Main Activities

  • Component 1- Mapping of Greater Banjul and Assessing Subsidence: This component aims to prepare a resilience plan, for Banjul’s population and economy. One of the objectives is to accurately map, according to different sea level rise scenarios, how the city is concentrating people and assets.
  • Component 2- Greater Banjul Flood and Sea Level Rise Risk Assessment: Building on the digital elevation model and mapping of buildings from Component 1, a detailed risk assessment of Banjul is being developed.
  • Component 3- Coastal Risk Assessment: A more accurate understanding of the dynamics of coastal erosion and the main hotspots need to be better defined. Activities under this component include using satellite imagery to measure coastal geomorphology along the coastline over the past 30 years to identify hotspots.
  • Component 4- Data Management and visualization: The data, models and maps generated by the above activities will be uploaded onto an open source platform for sharing risk-related data.

Results

A consulting firm was hired to support the detailed assessment of the greatest flood and coastal risks in the Greater Banjul region, and to identify and prioritize necessary measures and investments that will inform the Government of the Gambia on how to mitigate the consequences of these hazards. 

A file with existing data on flood dynamics, flood and coastal modelling, and priority investment planning was generated to serve as a baseline to support the consulting firm in carrying out its detailed assessment.

Partnerships and Coordination

The project is carried out by the World Bank, in collaboration with the Office of the Vice President, the Ministry of Finance and Economic Affairs, the National Disaster Management Agency, the Banjul City Council, and the Kanifing Municipal Council.
