Geography

Sudan is situated in Northern Africa, with a coastline of 853 km along the Red Sea. With an area of 2,505,810 square kilometres (967,499 sq mi), it is the largest country in the continent and the tenth largest in the world. It is approximately a quarter of the size of the US, and ten times the size of the UK.

Borders

Sudan is bordered by Egypt to the north, the Red Sea to the northeast, Eritrea and Ethiopia to the east, Kenya and Uganda to the southeast, Democratic Republic of the Congo and the Central African Republic to the southwest, Chad to the west and Libya to the northwest.

Terrain

The terrain is generally flat plains, broken by several mountain ranges; in the west the Jebel Marra is the highest range; in the south is the highest mountain Mount Kinyeti Imatong, near the border with Uganda; whilst in the east are the Red Sea Hills.

Rivers and Rainfall

The Blue and White Niles meet in Khartoum to form the River Nile, which flows northwards through Egypt to the Mediterranean Sea. Blue Nile's course through Sudan is nearly 500 miles long and is joined by the rivers Dinder and Rahad between Sennar and Khartoum. The White Nile within Sudan has no significant tributaries.

There are several dams on the Blue and White Niles. Among them are the Sennar and Roseires on the Blue Nile, and Jebel Aulia dam on the White Nile. There is also Lake Nubia on the Sudan-Egyptian border.

The amount of rainfall increases towards the south. In the north there is the very dry Nubian desert; in the south there are swamps and rain forest. Sudan's rainy season lasts for about three months (July to September) in the north, and up to six months (June to November) in the south. The dry regions are plagued by sand storms, known as haboob, which can completely block out the sun. In the northern and western semi-desert areas, people rely on the scant rainfall for basic agriculture and many are nomadic, travelling with their herds of sheep and camels. Nearer the River Nile, there are well-irrigated farms growing cash crops.

Resources

Rich mineral resources are available in Sudan including: petroleum, natural gas, gold, silver, chrome, asbestos, manganese, gypsum, mica, zinc, iron, lead, uranium, copper, kaolin, cobalt, granite, nickel and tin.

Environmental Concerns

Desertification is a serious problem in Sudan. There is also concern over soil erosion. Agricultural expansion, both public and private, has proceeded without conservation measures. The consequences have manifested themselves in the form of deforestation, soil desiccation, and the lowering of soil fertility and the water table.
