description Volta Delta Overview
The Volta Delta is located in southeastern Ghana where the Volta River flows into the Gulf of Guinea. It features the Keta Lagoon, the largest lagoon in Ghana, which is an important wetland ecosystem and habitat for migratory birds. The delta region is densely populated and supports fishing and agriculture, but it faces severe environmental challenges from coastal erosion and flooding. The construction of the Akosombo Dam upstream altered the sediment supply, worsening the coastal erosion.
