Chad BasinThe Chad Basin is the largest endorheic basin in Africa, centered approximately on Lake Chad. It has no outlet to the sea and contains large areas of semi-arid desert and savanna. The drainage basin is approximately coterminous with the sedimentary basin of the same name, but extends further to the northeast and east. The basin spans eight modern nations, including most of Chad and a large part of Niger, Algeria, Libya, Sudan, Nigeria, Cameroon, Central African Republic.
Kanem–Bornu EmpireThe Kanem–Bornu Empire existed in areas which are now part of Nigeria, Niger, Cameroon, Libya and Chad. It was known to the Arabian geographers as the Kanem Empire from the 8th century AD onward and lasted as the independent kingdom of Bornu (the Bornu Empire) until 1900. The Kanem Empire (c. 700–1380) was located in the present countries of Chad, Nigeria and Libya. At its height, it encompassed an area covering not only most of Chad but also parts of southern Libya (Fezzan) and eastern Niger, northeastern Nigeria and northern Cameroon.
Kanuri peopleThe Kanuri people (Kanouri, Kanowri, also Yerwa, Baribari and several subgroup names) are an African ethnic group living largely in the lands of the former Kanem and Bornu Empires in Niger, Nigeria, Sudan, Libya and Cameroon. Those generally termed Kanuri include several subgroups and dialect groups, some of whom identify as distinct from the Kanuri. Most trace their origins to ruling lineages of the medieval Kanem-Bornu Empire, and its client states or provinces.
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.
ChadChad (tʃæd ), officially the Republic of Chad, is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the southwest, Nigeria to the southwest (at Lake Chad), and Niger to the west. Chad has a population of 16 million, of which 1.6 million live in the capital and largest city of N'Djamena. Chad 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.
