COASTAL FLOODING AND EROSION UNDER CLIMATE CHANGE: A RISK ASSESSMENT FOR DAKAR

The report assesses coastal risks in the Dakar region, specifically within the departments of Dakar, Pikine, and Guédiawaye. It identifies high-risk areas for flooding, such as the canal of Ngor and the Port of Dakar, and high-risk areas for erosion, including the beach of Hanika. Projections indicate that without adaptation, the population at risk of coastal flooding will increase by 20-30% by 2050 and over 80% by 2100. Economic damages to buildings are expected to rise by 30% by 2050 and up to 180% by 2100 under the worst-case scenario.

• The areas most vulnerable to coastal flooding in the Dakar region include the canal of Ngor, the flat areas surrounding the Port of Dakar, and the chemical industrial facilities (ICS) in Mbao.
• Coastal erosion is most severe along the long beach of Hanika in the Grand Côte and the narrow beaches stretching from Hann to Mbao.
• Without the implementation of adaptation measures, the population exposed to coastal flooding from sea-level rise and extreme events is projected to grow by 20-30% by 2050 and by more than 80% by 2100.
• Under a middle-of-the-road sea-level rise scenario and in the absence of adaptation, economic damages to buildings are expected to increase by 30% by 2050 and by 80% by 2100.
• Current annual economic damages to buildings are estimated at approximately 3-4 million USD, with the potential for damages to increase between 80% and 180% by 2100 depending on the sea-level rise scenario.
• Coastal erosion in Dakar is driven by both natural processes, such as sea-level rise and sand deficit, and anthropogenic activities, including sand extraction for construction and inadequate urban planning.
