Chad is located in the north central part of Africa.
Compared to other countries Chad is the the fifth largest in Africa with 1,259,200 Km2 of Land and 24,800 Km2 of water.
C) Land frontiers
Chad has 5968 km of land frontiers with Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon and Nigeria to the southwest and Niger to the west.
Sudan’s climate ranges from desert in the north of the country to savanna in the south. Each year a tropical weather system known as the intertropical front crosses Chad from south to north, bringing a wet season that lasts from May to October in the south, and from June to September in the Sahel. Variations in local rainfall create three major geographical zones. The Sahara lies in the country's northern third. Yearly precipitations throughout this belt are under 50 millimetres ; only the occasional spontaneous palm grove survives, and the only ones to do so are south of the Tropic of Cancer.
The Sahara gives way to a Sahelian belt in Chad's centre; precipitation there varies from 300 to 600 mm per year. In the Sahel, a steppe of thorny bushes (mostly acacias) gradually gives way to the south to East Sudanian savanna in Chad's Sudanese zone. Yearly rainfall in this belt is over 900 mm.
E) Airports and seaports
In Chad there are over 20 internationally certified airstrips with 6 of these having asphalt strips, there is an additional 30 laterite strips around the country. (https://en.wikipedia.org/wiki/List_of_airports_in_Chad)
Broad, arid plains in center, desert in north, mountains in northwest, lowlands in south. Lowest point is Djourab at 160m elevation and the highest point is Emi Koussi at 3,415 m altitude
In 2016 the world bank put the Chadian population of 2014 at 13’587’053 (http://data.worldbank.org/country/chad).
Oil and agriculture drive Chad’s economy. At least 80% of Chad's population relies for its livelihood on subsistence farming and livestock raising and oil provides the bulk of export revenues. Cotton, cattle, and arabic gum provide the bulk of Chad's non-
