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] |
Ethiopian Montane Moorlands
The Ethiopian montane moorlands is a montane grasslands and shrublands ecoregion in Ethiopia. It lies above 3,000 meters elevation in the Ethiopian Highlands, the largest Afroalpine region in Africa. The montane moorlands lie above the tree line, and consist of grassland and moorland with abundant herbs and shrubs adapted to the high elevation conditions. Geography The ecoregion occupies an area of . The ecoregion covers areas above elevation, extending up to 4,550 meters on Ras Dashen, the highest peak in the Ethiopian Highlands.

Jubba River
The Jubba River or Juba River ( so, Wabiga Jubba) is a river in southern Somalia which flows through the autonomous region of Jubaland. It begins at the border with Ethiopia, where the Dawa and Ganale Dorya rivers meet, and flows directly south to the Somali Sea, where it empties at the ''Goobweyn'' juncture. The Jubba basin covers an area of . The Somali regional state of Jubaland, formerly called ''Trans-Juba'', is named after the river. History Ajuran Empire The Jubba River has a rich history of a once-booming sophisticated civilization and trade network conducted by the powerful Somalis that held sway over the Jubba river. During the Middle Ages Jubba river was under the Ajuran Empire of the Horn of Africa which utilized the Jubba River for its plantations and was the only hydraulic empire in Africa. A hydraulic empire that rose in the 13th century AD, Ajuran monopolized the water resources of the Jubba River and Shebelle. Through hydraulic engineering, it also construct ...

Shebelle River
The Shebelle River ( so, Webi Shabeelle, ar, نهر شبيلي, am, እደላ) begins in the Ethiopian Highlands, highlands of Ethiopia, and then flows southeast into Somalia towards Mogadishu. Near Mogadishu, it turns sharply southwest, where it follows the coast. Below Mogadishu, the river becomes seasonal. During most years, the river dries up near the mouth of the Jubba River, while in seasons of heavy rainfall, the river actually reaches the Jubba and thus the Somali Sea. The Shebelle river's name is derived from the Somali term ''Webi Shabeelle'', meaning "Leopard River". The Somali administrative regions consisting of Middle Shebelle and Lower Shabeelle are also named after the river. Tributaries The Shebelle has a number of Tributary, tributaries, both seasonal and permanent rivers. They include: * Erer River * Galetti River * Wabe River (Arsi), Wabe River The Fafen River, Fafen only reaches the Shebelle in times of heavy rainfall; its stream usually ends before reachi ...

Lake Turkana
Lake Turkana (), formerly known as Lake Rudolf, is a lake in the Kenyan Rift Valley, in northern Kenya, with its far northern end crossing into Ethiopia. It is the world's largest permanent desert lake and the world's largest alkaline lake. By volume it is the world's fourth-largest salt lake after the Caspian Sea, Issyk-Kul, and Lake Van (passing the shrinking South Aral Sea), and among all lakes it ranks 24th. Lake Turkana is now threatened by the construction of Gilgel Gibe III Dam in Ethiopia due to the damming of the Omo river which supplies most of the lake's water. Although the lake commonly has been —and to some degree still is— used for drinking water, its salinity (slightly brackish) and very high levels of fluoride (much higher than in fluoridated water) generally make it unsuitable, and it has also been a source of diseases spread by contaminated water. Increasingly, communities on the lake's shores rely on underground springs for drinking water. The same c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Tana
Lake Tana ( am, ጣና ሐይቅ, T’ana ḥāyik’i; previously Tsana) is the largest lake in Ethiopia and the source of the Blue Nile. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately long and wide, with a maximum depth of , and an elevation of . Lake Tana is fed by the Gilgel Abay, Reb and Gumara rivers. Its surface area ranges from , depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls (Tis Abbai) and hydro-power station. In 2015, the Lake Tana region was nominated as a UNESCO Biosphere Reserve recognizing its national and international natural and cultural importance. Overview Lake Tana was formed by volcanic activity, blocking the course of inflowing rivers in the early Pleistocene epoch, about 5 million years ago. The lake was originally much larger than it is today. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethiopian Highlands
The Ethiopian Highlands is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the Roof of Africa due to its height and large area. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval early modern state, whence the coffee plant was exported to the Arabian Peninsula. The land of the former kingdom is mountainous with stretches of forest. The land is very fertile, capable of three harvests a year. The term ''coffee'' derives from the ar, قهوة, italic=no ()''Oxford English Dictionary'', 1st ed. "coffee, ''n.''" Oxford University Press (Oxford), 1891. and is traced to Kaffa.

Ethiopian Xeric Grasslands And Shrublands
The Ethiopian xeric grasslands and shrublands ecoregion is a semi-desert strip on or near the Red Sea and the Gulf of Aden coasts in Eritrea, Ethiopia, Djibouti and Somaliland. This ecoregion lies mainly between sea level and 800 meters (m) elevation. There are, however, many hills and massifs, which range up to 1300 m as well as outstanding fault-induced depressions, such as the Danakil, lying as low as 155 m below sea level. This region is extremely active tectonically, experiencing many earthquakes and intermittently active volcanoes. Rainfall is very low and yearly averages range from 100 to 200 millimeters (mm), with less rain falling closer to the coast. There are many species of interest, including the endemic Archer's lark (''Heteromirafra archeri''), a species of dragon tree ('' Dracaena ombet''), and a large suite of desert ungulates, including the last viable population of African wild ass (''Equus africanus somalicus'').

Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi, become quite cold in winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water.
