Lake Chad, Chad/Cameroon/Nigeria/Niger

Located at the edge of the Sahara Desert, Lake Chad is one of numerous large lakes that might dry out soon. A source of water for about 70 million people living in the surrounding countries, the lake has already lost as much as 95% of its volume from 1963 to 1998. Over-usage by the locals, changes in rainfall patterns and deforestation are the primary reason for the lake drying, however recent studies have shown some improvement.
