Geography of Ethiopia

Source: Wikipedia, the free encyclopedia.

Ethiopia is located in the Horn of Africa. It is bordered by Eritrea to the north, Djibouti and Somalia to the east, Sudan and South Sudan to the west, and Kenya to the south. Ethiopia has a high central plateau, the Abyssinian Highlands (or Ethiopian Highlands) that varies from 1,290 to 3,000 m (4,232 to 9,843 ft) above sea level, with some 25 mountains whose peaks rise over 4,000 meters (13,200ft), the highest being Ras Dashen at 4,543 meters (14,538ft).[1]

Elevation is generally highest just before the point of descent to the Great Rift Valley, which splits the plateau diagonally. A number of rivers cross the plateau; notably the Blue Nile rising from Lake Tana. The plateau gradually slopes to the lowlands of the Sudan on the west and the Somali-inhabited plains to the east. Ethiopia's westernmost locality is Pibor River opposite the Sudanese village of Denjok. Its easternmost locality lies along the eastern border of Dollo Zone opposite Puntland and Galmudug states.

Between the valley of the Upper

Annesley Bay (also known as the Bay of Zula) (15° N). It then turns due south into Ethiopia and follows closely the line of 40° E for some 600 km (373 mi).[2]

About 9° N there is a break in the wall, through which the Awash River flows eastward. The main range at this point trends southwest, while south of the Awash Valley, which is some 1,000 m (3,281 ft) below the level of the mountains, another massif rises in a direct line south. This second range sends a chain (the Ahmar Mountains) eastward toward the Gulf of Aden.[3]

The two chief eastern ranges maintain a parallel course south by west, with a broad upland valley in between – in which valley are a series of lakes – to about

Southern Nations, Nationalities, and Peoples Region).[4]

The western wall of the plateau from 6° N to 11° N is well marked and precipitous. North of 11° N the hills turn more to the east and fall more gradually to the East Sudanian savanna plains at their base. On its northern face, the plateau falls in terraces to the level of the eastern Sudan.

Awash river valley.

The eastern escarpment is the best defined of these outer ranges. It has a mean height of 2,100 to 2,400 m (6,890 to 7,874 ft), and in many places rises almost perpendicularly from the plain. Narrow and deep clefts, through which descend mountain torrents that lose themselves in the sandy soil of the Eritrean coast, afford means of reaching the plateau, or the easier route through the Awash Valley may be chosen. On surmounting this rocky barrier, the traveller finds that the encircling rampart rises little above the normal level of the plateau.[4]

The physical aspect of the highlands is impressive. The northern portion lies mainly between 10° and 15° N. It consists of a huge mass of Archaean rocks with a mean height of 2,000 to 2,200 m (6,562 to 7,218 ft) above sea level, and is flooded in a deep central depression by the waters of Lake Tana. Above the plateau rise several irregular and generally ill-defined mountain ranges which attain altitudes of from 3,700 m (12,139 ft) to just under 4,600 m (15,092 ft). Many of the mountains are of unusual shape.[4]

Characteristic of the country are the enormous

ambas, with nearly perpendicular sides.[4]

The highest peaks are found in the

Biuat and Abba Yared, whose summits are less than 100 meters (328 ft) below that of Ras Dashen.[4]

The Bale Mountains are separated from the larger part of the Ethiopian highlands by the

Tullu Demtu, the second-highest mountain in Ethiopia (4,377 m or 14,360 ft), Batu (4,307 m or 14,131 ft), Chilalo (4,036 m or 13,241 ft) and Mount Kaka
(3,820 m or 12,533 ft).

Parallel with the eastern escarpment are the heights of

(also known as Mount Birhan) attains a height of 4,154 m (13,629 ft).

Below 10° N, the southern portion of the highlands has more open tableland than the northern portion and fewer lofty peaks. Though there are a few heights between 3,000 and 4,000 m (9,843 and 13,123 ft), the majority do not exceed 2,400 m (7,874 ft), but the general character of the southern regions is the same as in the north: a much-broken hilly plateau.[4]

Hydrology

Hydrogeology map of Ethiopia

Most of the Ethiopian uplands have a decided slope to the northwest, so that nearly all the large rivers flow in that direction to the

endorheic Turkana Basin with Lake Turkana. The rest is carried off by the Awash, which runs out in the saline lacustrine district along the border with Djibouti; by the Shebelle River and the Jubba, which flow southeast through Somalia, though the Shebelle most often fails to reach the Indian Ocean.[4]

In Sudan, the Setit is joined (at 14°20′N 35°51′E / 14.333°N 35.850°E / 14.333; 35.850) by the Atbarah, a river formed by several streams which rise in the mountains west and northwest of Lake Tana. The Gash or Mareb, which forms part of the border with Eritrea, is the most northerly of the highland rivers which flow toward the Nile valley. Its headwaters rise on the landward side of the eastern escarpment within 80 km of Annesley Bay on the Red Sea. It reaches the Sudanese plains near Kassala, beyond which place its waters are dissipated in the sandy soil. The Mareb is dry for a great part of the year, but like the Takazze is subject to sudden freshets during the rainy season. Only the left bank of the upper course of the river is in Ethiopian territory.[4] The Abay – that is, the upper course of the Blue Nile – has its source near

Kaffa hills and has a generally south-to-north course; the Dabus runs near the western edge of the plateau escarpment. All these are perennial rivers. The right-hand tributaries, rising mostly on the western sides of the plateau, have steep slopes and are generally torrential in character. The Beles, however, is perennial, and the Rahad and Dinder are important rivers in flood-time.[4]

In the mountains and plateaus of

Gelo, Akobo and other chief affluents of the Sobat tributary of the Nile. The Akobo, in about 7°47′N 33°3′E / 7.783°N 33.050°E / 7.783; 33.050, joins the Pibor, which in about 8°30′N 33°20′E / 8.500°N 33.333°E / 8.500; 33.333 unites with the Baro, the river below the confluence taking the name of Sobat. These rivers descend from the mountains in great falls, and like the other Ethiopian streams are unnavigable in their upper courses. The Baro on reaching the plain becomes, however, a navigable stream affording an open waterway to the Nile. The Baro, Pibor and Akobo form for 400 km (249 mi) the western and southwestern frontiers of Ethiopia.[4]

The chief river of Ethiopia flowing east is the

Germama (Kasam), and then trends round in the direction of the Gulf of Tadjoura. Here the Awash is a copious stream nearly 60 m (197 ft) wide and 1.2 m (3.94 ft) deep, even in the dry season, and during the floods rising 15 to 20 m (49 to 66 ft) above low-water mark, thus inundating the plains for many kilometers along both its banks.[4]

Flamingos at Lake Abbe.

After a winding course of about 800 km (497 mi), the Awash River passes (in its lower reaches) through a series of badds (lagoons) to Lake Abbe (or Abhe Bid) on the border with Djibouti and some 100 to 110 km (62 to 68 mi) from the head of the Gulf of Tadjoura. In this lake the Awash river is lost. This remarkable phenomenon is explained by the position of Lake Abbe in the centre of a saline lacustrine depression several hundred meters below sea level. While most of the other lagoons are highly saline, with thick incrustations of salt round their margins, Lake Abbe remains fresh throughout the year, owing to the great body of water discharged into it by the Awash.[5]

Another lacustrine region extends from the Shoan heights southwest to the Samburu (

Zway, communicating southwards with Hara and Lamina, all in the Arsi Zone; then Abijatta with an outlet to a smaller turn to the Baroda and Gamo areas, skirted on the west sides by grassy slopes and wooded ranges from 2,000 m (6,562 ft) to nearly 3,000 m (9,843 ft) high; lastly, Lake Chew Bahir (formerly known as Lake Stephanie) which is completely closed and falling to a level of about 550 m (1,804 ft) above sea level.[6]

To the same system belongs the neighbouring Lake Turkana, which is larger than all the rest put together. This lake receives at its northern end the waters of the Omo, which rises in the Shoan highlands and is a perennial river with many affluents. In its course of some 600 km (373 mi) it has a total fall of about 700 m (2,297 ft), from 1,060 m (3,478 ft) at its source to c. 360 m (1,181 ft) at lake level, and is consequently a rapid stream, being broken by the Kokobi and other falls, and navigable only for a short distance above its mouth.[6]

The chief rivers of Somalia, the Shebelle and the Jubba, rise on the southeastern slopes of the Ethiopian escarpment as the Shebelle, the Ganale Doria and the Dawa, and part of their course is through territory belonging to Ethiopia.[6]

There are numerous hot springs in Ethiopia, such as Sodere.

Geology

The East African

Afar Depression, due to its importance as one of two places on Earth where a mid-ocean ridge can be studied on land (the other is Iceland
).

The following formations are represented:

Archaean.– The metamorphic rocks compose the main mass of the tableland, and are exposed in every deep valley in Tigre and along the valley of the Blue Nile. Mica-schists form the prevalent rocks. Hornblende schists also occur and a compact feldspathic rock in the Suris defile. The folia of the schists strike north and south.[6]

Karoo System of South Africa.[6]

Jurassic.– The fossiliferous Antalo Limestones are generally horizontal, but are in places much disturbed when interstratified with Mekelle Dolerite. The fossils are all characteristic Oolite forms and include species of Hemicidaris, Pholadomya, Ceromya, Trigonia and Alaria.[6]

Igneous Rocks.– Above a height of 2,400 m (7,900 ft) the country consists of bedded traps belonging to two distinct and unconformable groups. The lower (Ashangi group) consists of basalts and dolerites often amygdaloidal. Their relation to the Antalo limestones is uncertain, but Blanford considers them to be not later in age than the Oolite. The upper (Magdala group) contains much trachytic rock of considerable thickness, lying perfectly horizontally, and giving rise to a series of terraced ridges characteristic of central Ethiopia. They are interbedded with unfossiliferous sandstones and shales.[6]

Of more recent date (probably Tertiary) are some igneous rocks, rich in alkalis, occurring in certain localities in southern Ethiopia. Of still more recent date are the basalts and ashes west of Massawa and around Annesley Bay and known as the Aden Volcanic Series. With regard to the older igneous rocks, the enormous amount they have suffered from denudation is a prominent feature. They have been worn into deep and narrow ravines, sometimes to a depth of 1,000 to 1,200 m (3,300 to 3,900 ft).[6]

Climate

Köppen climate classification zones of Ethiopia

The

Afar Region have a hot, sunny and dry climate producing fully desert or semi-desert conditions. The terrain in the lower basin of the Sobat is hot, swampy and malarious.[6]

In the uplands, the air is cool and bracing in summer, and in winter very bleak. The mean range of temperature is between 15 and 25 °C (59 and 77 °F). On the higher mountains the climate is alpine in character. The atmosphere on the plateaus is exceedingly clear, so that objects are easily recognizable at great distances. In addition to the variation in climate dependent on elevation, the year may be divided into three seasons. Winter, or the cold season, lasts from October to February. It is followed by a dry hot period, which about the middle of June gives place to the rainy season. The rain is heaviest in the Tekezé basin in July and August.[6]

In the former provinces of Gojjam and Welega, heavy rains continue till the middle of September. October is occasionally a wet month. There are also spring and winter rains; indeed rain often falls in every month of the year. But the rainy season proper, caused by the southwest monsoon, lasts from June to mid-September, and commencing in the north moves southward. In the region of the headwaters of the Sobat the rains begin earlier and last longer. The rainfall varies from about 750 mm (29.5 in) a year in Tigray and Amhara to over 1,000 mm (39.4 in) in parts of Oromia.[6]

The rainy season is of great importance not only to Ethiopia but to the countries of the Nile valley, as the prosperity of the eastern Sudan and Egypt is largely dependent upon the rainfall. A season of light rain may be sufficient for the needs of Ethiopia, but there is little surplus water to find its way to the Nile; and a shortness of rain means a low Nile, as practically all the flood water of that river is derived from the Ethiopian tributaries.[6]

Flora and fauna

Flora

As in a day's journey the traveller may pass from tropical to almost Alpine conditions of climate, so great also is the range of the flora and fauna. In the valleys and lowlands the vegetation is dense, but the general appearance of the plateaus is of a comparatively bare country with trees and bushes thinly scattered over it. The glens and ravines on the hillside are often thickly wooded, and offer a delightful contrast to the open downs.[6]

These conditions are particularly characteristic of the northern regions; in the south the vegetation on the uplands is more luxuriant. Among the many varieties of trees and plants found are the date palm,

sugar cane. There are in the south large forests of valuable timber trees; and the coffee plant is indigenous in the Kaffa country, whence it takes its name.[18]

Many kinds of

semi-desert regions of the north and south-east.[19]

Fauna

In addition to the domestic animals enumerated below the fauna is very varied. Elephant can be found in certain low-lying districts, especially in the Sobat valley. The hippopotamus and crocodile inhabit the larger rivers flowing west, but are not found in the Hawash, in which, however, otters of large size are plentiful. Lions abound in the low countries. In central Ethiopia the lion is no longer found except occasionally in the river valleys.[19]

badgers are more rarely seen. The giraffe is found in the western districts, the zebra and wild ass frequent the lower plateaus and the rocky hills of the north. There are large herds of buffalo and antelope, and gazelles of many varieties and in great numbers are met with in most parts of the country.[19]

Among the varieties are the greater and lesser

. They range from the tropical lowlands to heights of 3,000 m (9,843 ft).

Numerous

blackbird, parrot and jays of extraordinary brilliance.[19]

Among insects the most numerous and useful is the bee, honey everywhere constituting an important part of the food of the inhabitants. Of an opposite class is the locust. There are thousands of varieties of butterflies and other insects. Snakes are not numerous, but several species are venomous.[19]

Natural resources and land use

Ethiopia has small reserves of gold, platinum, copper, potash, and natural gas.[20] It has extensive hydropower potential.[20]

Of the total land area, about 20 percent is under cultivation, although the amount of potentially arable land is larger.

rapid deforestation during the last 30 years.[20] Of the remainder, a large portion is used as pasturage. Some land is too rugged, dry, or infertile for agriculture or any other use.[20]

Environmental issues

Disputed border

Eritrea

The border between Ethiopia and Eritrea has never been precisely demarcated.[20] Between 1998 and 2000, the two countries fought a war over the issue, which involves quite small enclaves along the northern segment of their border, including the tiny village of Badme and the enclave of the Irob people.[20] An international boundary commission delimited the border in 2002.[20]

Although both nations agreed to accept its decision, Ethiopia has refused to accept the commission's findings in full, much to the consternation of the Eritrean government.[20]

Somalia

The central section of Ethiopia's border with Somalia also has never been fully demarcated, and is only provisional.

Questions remain about the precise location of small parcels along the border with Sudan as well.[20]
