| Environment - current issues | inadequate supplies of potable water; improper waste disposal in rural areas and poor farming practices contribute to soil and water pollution; desertification | water pollution; inadequate supplies of potable water; water scarcity and periodic drought; wildlife populations threatened by excessive hunting; soil erosion; desertification; deforestation; loss of biodiversity

| Geography - note | note 1: Chad is the largest of Africa's 16 landlocked countries note 2: not long ago - geologically speaking - what is today the Sahara was green savannah teeming with wildlife; during the African Humid Period, roughly 11,000 to 5,000 years ago, a vibrant animal community, including elephants, giraffes, hippos, and antelope lived there; the last remnant of the "Green Sahara" exists in the Lakes of Ounianga (oo-nee-ahn-ga) in northern Chad, a series of 18 interconnected freshwater, saline, and hypersaline lakes now protected as a World Heritage site note 3: Lake Chad, the most significant water body in the Sahel, is a remnant of a former inland sea, paleolake Mega-Chad; at its greatest extent, sometime before 5000 B.C., Lake Mega-Chad was the largest of four Saharan paleolakes that existed during the African Humid Period; it covered an area of about 400,000 sq km (150,000 sq mi), roughly the size of today's Caspian Sea | the Nile is Sudan's primary water source; its major tributaries, the White Nile and the Blue Nile, meet at Khartoum to form the River Nile which flows northward through Egypt to the Mediterranean Sea |
| Total renewable water resources | 45.7 billion cubic meters (2017 est.) | 37.8 billion cubic meters (2017 est.) |
| Population distribution | the population is unevenly distributed due to contrasts in climate and physical geography; the highest density is found in the southwest, particularly around Lake Chad and points south; the dry Saharan zone to the north is the least densely populated as shown in this population distribution map | with the exception of a ribbon of settlement that corresponds to the banks of the Nile, northern Sudan, which extends into the dry Sahara, is sparsely populated; more abundant vegetation and broader access to water increases population distribution in the south extending habitable range along nearly the entire border with South Sudan; sizeable areas of population are found around Khartoum, southeast between the Blue and White Nile Rivers, and througout South Darfur as shown on this population distribution map |
