Which one of the following lakes of West Africa has become dry and turned into a desert?

1. The question asks to identify a specific lake in West Africa that has become dry and turned into a desert. 2. Lake Faguibine is located in Mali, West Africa. Historically, it was part of a system of lakes fed by the Niger River. 3. Due to factors including recurrent droughts linked to climate change and reduced inflow from the Niger River, Lake Faguibine has significantly shrunk and largely dried up, leading to desertification in the area. 4. Lake Victoria is the largest lake in Africa but is located in East Africa. 5. Lake Oguta is located in Nigeria, West Africa, but it has not turned into a desert. 6. Lake Volta in Ghana, West Africa, is one of the largest artificial reservoirs in the world and has not turned into a desert. 7. Therefore, Lake Faguibine is the correct answer.
