Benin’s coastline is eroding at some of the highest rates in the world, putting ecosystems, livelihoods, and infrastructure at risk. This publication examines a proposed WACA ResIP sub-project at the Bouche du Roy, designed to reduce flooding and control erosion through engineered and nature-based solutions. It focuses on strengthening the project’s Environmental and Social Impact Assessment to better align with World Bank biodiversity standards and protect critical natural habitats.
