The cost of coastal zone degradation in Nigeria: Cross river, delta and lagos states

This report adresses the question of Nigeria's fragile coastal areas. Using a consistent valuation methodology, it estimates the cost of coastal degradation in three Nigerian states: Cross River, Delta and Lagos.

The results are striking: in 2018 alone, floods, erosion and pollution in these three states cost society US$9.7 billion, or 2.4 percent of the country’s GDP. As this estimate covers less than a half of the country’s coastline, the total cost of coastal degradation in Nigeria is certainly higher.

This report demonstrates the benefits of doing a coordinated study that builds on state and local level analyses. Its findings will inform the country’s multi-sectoral investment plan for the coastal zone, and will support its efforts to mobilize financing for coastal resilience as part of the West Africa Coastal Areas program. Investing in coastal resilience will save lives and prevent future damages. The time is now.
