Chad is a landlocked country in northern Central Africa. It has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the largest wetland in Chad and the second-largest in Africa. N'Djamena is the capital and the largest city. Chad is home to over 200 different ethnic and linguistic groups.
