Desertification by Shrinking Lake Chad
Lake Chad is located in the Sahel, a vast savanna bordered by the rain forests of the west coast of Africa on one side and the Sahara desert to the north. Chad, Niger, Nigeria, and Cameroon are neighboring countries. Once one of Africa’s largest freshwater lakes, it has shrunk dramatically in the last 40 years. In 1963, the lake covered about 9,700 square miles (25,000 square kilometers); in 2001, it was only one-twentieth of that size.
