Chad is mostly made up of a dry, dusty, shallow basin. Lake Chad, the fourth largest lake in Africa., is situated to the west along the border with Cameroon. The lake is surrounded by mountains, including the volcanic Tibesti Massif, and high plateaus. The country has two rivers -- Chari and Logone -- with tributaries, all of which flow into Lake Chad.
Lake Chad is only a fraction of what it used to be. The lake is an important resource for several countries in Africa and people living around it say they worry that their livelihoods are in danger of disappearing too
