Lake Chad,satellite image,2007
Lake Chad,satellite image. Image 4 of 4. Lake Chad,located in the Sahel region just south of the Sahara,was the fourth largest lake in Africa in the 1960s and had an area of more than 26,000 square kilometres. However,by the 21st century its extent had shrunk to less than 1,500 square kilometres,around a twentieth of its size. This is due to its increased use for irrigation combined with droughts. Image obtained using the Landsat 7 satellite in 2007. Vegetation is coloured red,water is dark. For a series showing the lake's shrinkage from 1963 to 2007,see images C003/2034 - C003/2037
