Geography Of Sudan
Sudan is located in Northeast Africa. It is bordered by Egypt to the north, the Red Sea to the northeast, Eritrea and Ethiopia to the east, South Sudan to the south, the Central African Republic to the southwest, Chad to the west and Libya to the northwest. Sudan is the third largest country in Africa, after Algeria and the Democratic Republic of the Congo. It was the largest country on the continent until South Sudan split off from it in 2011. Geographical regions Northern Sudan –lying between the Egyptian border and Sennar– has two distinct parts, the desert and the Nile Valley. Though published in 2015, this work covers events in the whole of Sudan (including present-day South Sudan) until the 2011 secession of South Sudan. To the east of the Nile is the Nubian Desert and to the west, the Libyan Desert. Both are stony, with sandy dunes drifting over the landscape. There is virtually no rainfall in these deserts. Water in the Libyan desert is limited to a few small water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

East Saharan Montane Xeric Woodlands
The East Saharan montane xeric woodlands is an terrestrial ecoregion, ecoregion of central Africa, a number of high mountains in the middle of the huge area of savanna on the edge of the Sahara Desert. Location and description The ecoregion covers the higher elevations of the Ennedi Plateau and the Ouaddaï Highlands of eastern Chad and the extinct volcano system Jebel Marra in Darfur, western Sudan. These mountain ranges rise above the semi-desert sahelian Acacia savanna at the southern edge of the Sahara Desert. The ecoregion covers an area of . The summer rains are irregular, even more so in Chad than on Jebel Marra, which has two crater lakes. Flora Plant life includes many species typical of the sahel belt including ''Ammania gracilis'', the grass ''Panicum laetum'', the forb ''Chrozophora brocchiana'' and the herbs ''Farsetia stenoptera'', ''Indigofera senegalensis'' and ''Tephrosia gracilipes''.

Jabal Marrah
The Marrah Mountains or Marra Mountains (Fur language, Fur, Fugo Marra; , Jebel Marra) are a range of volcanic peaks in a massif that rises up to . They are the highest mountains in Sudan. Geography The mountains are located in the center of the Darfur region of Sudan on the border of the states of South Darfur and Central Darfur, with a smaller part of the range in the state of North Darfur. The highest point is Deriba Caldera. The upper reaches of the massif is a small area of temperate climate with high rainfall and permanent springs of water amidst the dry savanna and scrub of the Sahel below. Apart from the Aïr Mountains in Niger which are on the border of the Sahara proper, the Marrah Mountains are the only major mountain range in the otherwise flat Sahel, rising up to above the plain, but are relatively unknown owing to lack of development and political conflict in the region. The last eruption occurred around 1500 BC. The centre of activity was Deriba Caldera, and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurdufan
Kordofan ( ') is a former province of central Sudan. In 1994 it was divided into three new federal states: North Kordofan, South Kordofan and West Kordofan. In August 2005, West Kordofan State was abolished and its territory divided between North and South Kordofan States, as part of the implementation of the Comprehensive Peace Agreement between the Government of Sudan and the Sudan People's Liberation Movement. West Kordofan was reestablished in July 2013. Geography Kordofan covers an area of some 376,145 km2 (146,932 miles²), with an estimated population in 2000 of 3.6 million (3 million in 1983). It is largely an undulating plain, with the Nuba Mountains in the southeast quarter. During the rainy season from June to September, the area is fertile, but in the dry season, it is virtually desert. The region's chief town is El-Obeid.

Paris: IRD éditions. . that sustains plant life and provides habitat for animals. Surface water may be present, or water may only be accessible from wells or underground channels created by humans. In geography, an oasis may be a current or past rest stop on a transportation route, or less-than-verdant location that nonetheless provides access to underground water through deep wells created and maintained by humans. Although they depend on a natural condition, such as the presence of water that may be stored in reservoirs and us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camel Train
A camel train, caravan, or camel string is a series of camels carrying passengers and goods on a regular or semi-regular service between points. Despite rarely travelling faster than human walking speed, for centuries camels' ability to withstand harsh conditions made them ideal for communication and trade in the desert areas of North Africa and the Arabian Peninsula. Camel trains were also used sparingly elsewhere around the globe. Since the early 20th century they have been largely replaced by motorized vehicles or air traffic. Africa, Asia and the Middle East By far, the greatest use of camel trains occurs between North and West Africa by the Tuareg, Shuwa and Hassaniyya, as well as by culturally-affiliated groups like the Toubou, Hausa and Songhay. These camel trains conduct trade in and around the Sahara Desert and Sahel. Trains travel as far south as central Nigeria and northern Cameroon in the west, and northern Kenya in the east of the continent. In antiquity, th ...

Nomad
Nomads are communities without fixed habitation who regularly move to and from areas. Such groups include hunter-gatherers, pastoral nomads (owning livestock), tinkers and trader nomads. In the twentieth century, the population of nomadic pastoral tribes slowly decreased, reaching an estimated 30–40 million nomads in the world . Nomadic hunting and gathering—following seasonally available wild plants and game—is by far the oldest human subsistence method known. Pastoralists raise herds of domesticated livestock, driving or accompanying them in patterns that normally avoid depleting pastures beyond their ability to recover. Nomadism is also a lifestyle adapted to infertile regions such as steppe, tundra, or ice and sand, where mobility is the most efficient strategy for exploiting scarce resources. For example, many groups living in the tundra are reindeer herders and are semi-nomadic, following forage for their animals. Sometimes also described as "nomadic" are vari ...

Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called ''Erg (landform), ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the wiktionary:stoss, stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of Outwash plain, glacial outwash ...
