At a Glance

The West Africa Regional Mission serves Benin, Burkina Faso, Cabo Verde, Cameroon, Chad, Côte d’Ivoire, Equatorial Guinea, Gabon, Ghana, Guinea, Guinea Bissau, Liberia, Mali, Mauritania, Niger, Nigeria, Sao Tome and Principe, Senegal, Sierra Leone, Togo, and The Gambia.

West Africa’s rich forest and coastal resources are increasingly at risk due to recurrent droughts, rising sea levels and deforestation with large consequences for economic development and food security. To address the region’s vulnerability to climate change and climate-related shocks, USAID is working with countries to improve the management of forests and mangroves, with the twin goals of reducing greenhouse gas emissions by increasing sequestration and increasing the resilience of the region’s coastal communities and upland systems. Clean energy programming will provide assistance to help eliminate the main obstacles to investment in low emissions development.
