COASTAL CHALLENGES IN WEST AFRICA

 

Coastal erosion and flooding in West Africa severely threaten people’s communities, livelihoods, safety and investments. About 56% of West Africa’s GDP is generated in coastal provinces, where one-third of the population resides. Stronger storms and rising seas are wiping out homes, roads and buildings that have served as landmarks for generations. Some beaches are deeply mined for sand, protective mangroves are deforested, and people are increasingly vulnerable to the impact of climate change. Some residents have no choice but to move away—a trend that is breaking up communities and changing the social fabric for future generations.

Rapid and often unplanned urbanization has devastated the natural landscape that once served as a buffer for erosion and flooding. These developments disproportionately affect the poorest and most marginalized, and will intensify due to climate change. While countries have started to contain erosion and flooding, there is an urgent need for partners to mobilize financing through coordinated regional action. Collaboration at the policy and technical levels helps countries to manage erosion hotspots, and to maintain the livelihoods that a healthy coastal ecosystem provides to people and economies.
