Which one of the following lakes of West Africa has become dry and turned into a desert ?
- A.Lake Victoria
- B.Lake Faguibine
- C.Lake Oguta
- D.Lake Volta
Correct answer
Explanation
The correct answer is B, Lake Faguibine. Lake Faguibine in northern Mali, once one of the largest lakes of West Africa, has dried up and turned into desert.
Faguibine lies west of Timbuktu and was filled by the yearly floods of the Niger river through a system of channels. In the 1970s and 1980s the Sahel droughts cut these floods, and the lake of about 600 square kilometres dried out almost completely. Fishing, farming and herding communities around it lost their livelihoods, and the bed is now sand and shrub. The UN Environment Programme cites it as a case of climate change and desertification in the Sahel.
A is wrong: Lake Victoria is in East Africa, shared by Uganda, Kenya and Tanzania, and is Africa's largest lake; it has not dried up.
C is wrong: Lake Oguta in Nigeria still holds water.
D is wrong: Lake Volta in Ghana is one of the world's largest man-made reservoirs, formed by the Akosombo Dam.
Exam tip: dried lakes – Faguibine (Mali), Lake Chad (shrunk), Aral Sea (Central Asia).
