The West Africa Regional Mission serves Benin, Burkina Faso, Cameroon, Cape Verde, Chad, Côte d’Ivoire, Equatorial Guinea, Guinea Bissau, Liberia, Mauritania, Niger, Nigeria, and Sierra Leone, 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.

Stories from the Area

Like SARS-CoV-2, the virus that causes COVID-19, the Ebola virus is a zoonotic pathogen that can be transmitted between animals and humans.
Deforestation, forest degradation, poaching, and environmental problems caused by climate change pose serious threats to many of West Africa’s already fragile ecosystems, including the region’s biodiversity-rich forests. Award-winning international journalist David Goodman learned about the severity of these threats as he traveled to the countries of Sierra Leone and Liberia to document the work of the USAID-funded West Africa Biodiversity and Climate Change (WA BiCC) Program.
The tropical air hangs over the Sierra Leonean coastal village of Gbongboma like a moist towel. Musa Lahai sits in an enclave of thatched huts, surrounded by women and children sitting around two cooking fires. Orange flames lick the sides of several large kettles of fish stew. Each fish was hard to come by. “Before, we were catching good fish. Now, we’re not,” Lahai says. He is deputy chief of the village, where approximately 90 people survive off earth’s bounties, from harvesting oysters, to deep sea fishing, to farming and growing palm fruit.
