Sea level rise – one of the consequences of global climate change – is predicted to adversely affect low-lying coastal settlements. Coastal settlements of Accra, the capital city of Ghana, could potentially experience the brunt of sea level rise. Examining three sea level rise scenarios evolved by the Intergovernmental Panel on Climate Change, this study estimates the potential economic cost of sea level rise on a market land along the coast of Accra. The objective is to identify the least cost adaptation option for coastal management in Ghana. The study established that protection of the coastline is the best adaptation strategy and that constructing a sea wall every 10 years to protect the land is the cheapest protection approach to pursue.
