Grand-Lahou Lagoon (Côte d’Ivoire)

Weather…

The Grand-Lahou Lagoon, also known as the Tagba Lagoon, is an ecologically sensitive body of water located where the Bandama River meets the Atlantic Ocean in southern Ivory Coast. It is a vital component of the country's coastal ecosystem, characterized by extensive mangrove forests that serve as nurseries for marine life and natural barriers against storm surges. The town of Grand-Lahou, once a prominent colonial trading post, is uniquely positioned on a precarious sandspit between the lagoon and the sea. Today, the area is at the forefront of the global climate crisis, as severe coastal erosion causes the shoreline to retreat rapidly, submerging historic buildings. The lagoon's brackish waters are essential for the local economy, supporting a large artisanal fishing community and providing a sheltered waterway for transport. Conservation efforts in the region focus on mangrove restoration and sustainable coastal management to protect both the environment and the livelihoods of the resident population.
