Lake ChadLake Chad (Kanuri: Sádǝ, Lac Tchad) is a freshwater lake located at the junction of Nigeria, Niger, Chad and Cameroon in central and western Africa. It is also an important wetland ecosystem in West Africa. The catchment area of Lake Chad is 1 million square kilometers. It used to be a large lake with an area of 28,000 square kilometers in the 19th century. However, due to climate change and human water diversion, Lake Chad has been greatly reduced since the mid-1970s, and its area has fluctuated between 2,000 and 5,000 square kilometers.
