Ouaddaï Highlands
Ouaddaï Highlands is an area in east of Chad along the border with Sudan. The Ennedi Plateau and the Ouaddaï highlands in the east of Chad complete the image of a gradually sloping basin, which descends towards Lake Chad. There are also central highlands in the Guera region rising to . Water systems Batha River is an important ephemeral river that carries water west from these highlands during rainy seasons, usually during flash flooding. The land Ouaddaï highlands mark Chad's eastern border and also divide the Chad and Nile watersheds. These highland areas are part of the East Saharan montane xeric woodlands ecoregion. Yellow Nile The Yellow Nile is a former tributary that connected the Ouaddaï highlands of eastern Chad to the Nile River Valley ca. 8000 to ca. 1000 BCE.Keding, B (2000).

Chad
Chad (; ar, تشاد , ; french: Tchad, ), 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. Lake Chad, after which the country is named, is the second-largest wetland in Africa. Chad's official languages are Arabic and French. It is home to over 200 different ethnic and linguistic groups. Islam (55.1%) and Christianity (41.1%) are the main religions practiced in Chad. Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbe ...

Wadi Howar
Wadi Howar (Wadi Howa) is a wadi in Sudan and Chad. Geography Originating in the Ennedi Region of Chad ''Wadi Howar'' runs through the Sudanese states of North Darfur and Northern to join the Nile north of the great bend opposite Old Dongola. Stretching over 1100 km in west–east direction across the southern fringes of the Libyan Desert, it ordinarily receives 25 mm of rainfall per year. Holocene period ''Wadi Howar'' is the remnant of the ancient ''Yellow Nile'', a tributary of the Nile during the Neolithic Subpluvial from about 9500 to 4500 years ago. At that time Savanna fauna and cattle-herders occupied this region and the southern edge of the Sahara was some 500 km further north than it is today. When the Sahara underwent desertification between 6000 and 4000 years ago, the wadi first became a chain of freshwater lakes and marshes, as shown by Ptolemy's world map, then it became extinct about 2000 years ago.

Geography Of Chad
Chad is one of the 47 landlocked countries in the world and is located in North Central Africa, measuring , nearly twice the size of France and slightly more than three times the size of California. Most of its ethnically and linguistically diverse population lives in the south, with densities ranging from 54 persons per square kilometer in the Logone River basin to 0.1 persons in the northern B.E.T. ( Borkou-Ennedi-Tibesti) desert region, which itself is larger than France. The capital city of N'Djaména, situated at the confluence of the Chari and Logone Rivers, is cosmopolitan in nature, with a current population in excess of 700,000 people. Chad has four climatic zones. The northernmost Saharan zone averages less than of rainfall annually. The sparse human population is largely nomadic, with some livestock, mostly small ruminants and camels. The central Sahelian zone receives between rainfall and has vegetation ranging from grass/shrub steppe to thorny, open savanna. Th ...

Kingdom Of Baguirmi
The Sultanate or Kingdom of Bagirmi or Baghermi (french: Royaume du Baguirmi) was a kingdom and Islamic sultanate southeast of Lake Chad in central Africa. It was founded in either 1480 or 1522 and lasted until 1897, when it became a French protectorate. Its capital was Massenya, north of the Chari River and close to the border to modern Cameroon. The kings wore the title ''Mbang''. History The Bagirmi carried a tradition that they migrated from far to the east, which is supported by the resemblance of their language to various tribes on the White Nile. It is not entirely clear when or by whom the Bagirimi kingdom was founded: some king lists trace this event to 1480, when it was supposedly founded by Mbang Abd al-Mahmud Begli, while others deem Mbang Birni Besse responsible, who is said to have founded the kingdom in 1522. He seems to have displaced the earlier Bulala, while he also began to build a palace in Massenya, the capital of the state. The fourth king, Abdullah (1568 ...

Sultanate Of Darfur
The Sultanate of Darfur was a pre-colonial state in present-day Sudan. It existed from 1603 to October 24, 1874, when it fell to the Sudanese warlord Rabih az-Zubayr and again from 1898 to 1916, when it was conquered by the British and integrated into Anglo-Egyptian Sudan. At its peak in the late 18th and early 19th century it stretched all the way from Darfur in the west to Kordofan and the western banks of the White Nile in the east, giving it the size of present-day Nigeria. History Origins Darfur is composed mostly of semi-arid plains that cannot support a dense population. The one exception is the area in and around the Jebal Marra mountains. It was from bases in these mountains that a series of groups expanded to control the region. The Daju and the 14th century migrants the Tunjur were the earliest powers in Darfur according to written records. The transition of power from the Daju to the Tunjur was facilitated through marriage. Eventually the Tunjur began marryin ...

Ouaddai Empire
The Wadai Sultanate ( ar, سلطنة وداي ''Saltanat Waday'', french: royaume du Ouaddaï, Fur: ''Burgu'' or ''Birgu''; 1501–1912) was an African sultanate located to the east of Lake Chad in present-day Chad and the Central African Republic. It emerged in the seventeenth century under the leadership of the first sultan, Abd al-Karim, who overthrew the ruling Tunjur people of the area. It occupied land previously held by the Sultanate of Darfur (in present-day Sudan) to the northeast of the Sultanate of Baguirmi. History Origins Prior to the 1630s, Wadai, also known as Burgu to the people of Darfur, was a pre-Islamic Tunjur kingdom, established around 1501. The Arab migrants to the area which became Wadai claimed to be descendants of the Abbasid Caliphs, specifically from Salih ibn Abdallah ibn Abbas. Yame, an Abbasid leader, settled with Arab migrants in Debba, near the future capital of Ouara (Wara). In 1635, the Maba and other small groups in the region rallied to ...

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Saharan Montane Xeric Woodlands
The East Saharan montane xeric woodlands is an 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.
