Natural Regions

Africa may be divided into three major regions: the Northern Plateau, the Central and Southern Plateau, and the Eastern Highlands. In general, elevations increase across the continent from northwest to southeast, the average being 600 m (1,900 ft). Low-lying coastal strips, with the exception of the Mediterranean coast and the Guinea coast, are generally narrow and rise sharply to the plateau.
The outstanding feature of the Northern Plateau is the Sahara, which occupies more than one-quarter of Africa. At the fringes of the Northern Plateau are several mountainous regions. To the northwest lie the Atlas Mountains, a chain of rugged peaks linked by high plateaus, which extend from Morocco into Tunisia. Other prominent uplands are the Fouta Djallon (Futa Jallon), on the southwest, and the Adamawa Plateau and the Cameroon mountain range, on the south. The Lake Chad Basin is situated in the approximate center of the Northern Plateau.

The Central and Southern Plateau is considerably higher than the Northern Plateau and includes west central and southern Africa. It contains several major depressions, notably the Congo River Basin and the Kalahari Desert. Other features south of this plateau, which averages more than 900 m (3,000 ft) in elevation, are the Drakensberg Mountains, running some 1,100 km (700 mi) along the southeastern coast, and in the extreme south, the High Veld, an arid plateau covering much of South Africa.
The Eastern Highlands, the highest portion of the continent, lie near the eastern coast, extending from the Red Sea south to the Zambezi River. The region has an average elevation of more than 2,000 m (5,000 ft), although in the Ethiopian Plateau it rises in stages to 3,000 m (10,000 ft). Ras Dashen (4,620 m/15,157 ft) in northern Ethiopia is the highest peak of the plateau. South of the Ethiopian Plateau are a number of towering volcanic peaks, including Kilimanjaro, Mount Kenya, and Mount Elgon.
A distinctive topographical feature of the Eastern Highlands is the Great Rift Valley, a vast geologic fault system that traverses the region in a northern to southern direction. West of the Great Rift Valley is the Ruwenzori Range, which attains a maximum elevation of 5,109 m (16,762 ft). The topography of the island of Madagascar features a rugged central highland extending in a generally north-south direction near the eastern coast.
Because most of the African continent has not been covered by the seas for millions of years, soils have developed locally, chiefly by weathering, and a few areas have benefited from soils transported by rivers or ocean currents. African soils, for the most part, have irregular drainage and no definite water tables. Most are relatively infertile due to mineral leaching from heavy rainfall and high temperatures. Desert soils (aridisols and entisols), which have little organic content, also cover large areas. The most fertile soils include the mollisols, also known as chernozems and black soils, of eastern Africa and the alfisols, or podzolic soils, of portions of western and southern Africa.
Relief is the general appearance of the landscape and it includes features like mountains, islands, Plateau, basins, rift valleys, inselbergs, Escarpments, coastal landforms divides.
Relief therefore stands for the physical background of a given area. Africa’s relief is dominated by three major relief features, which include: the African plateau, the Great Rift Valley and the coastal lands.

Sub-Saharan Africa

2008/9 Schools Wikipedia Selection. Related subjects: African Geography

Simplified climatic map of Africa: Sub-Saharan Africa consists of the aridSahel and the Horn of Africa in the north (yellow), the tropical savannas (light green) and the tropical rainforests (dark green) of Equatorial Africa, and the arid Kalahari Basin (yellow) and the " mediterranean" south coast (olive) ofSouthern Africa. The numbers shown correspond to the dates of ironartefacts associated with the Bantu expansion.

Sub-Saharan Africa is a geographical term used to describe the area of the African continent which lies south of the Sahara, or those African countries which are fully or partially located south of the Sahara.

It contrasts with North Africa, which is part of the Arab world.

The Sahel is the transitional zone between the Sahara and the tropical savanna (the Sûdân region) and forest-savanna mosaic to the south.

The Horn of Africa and Southern Sudan are geographically part of sub-Saharan Africa, but nevertheless show strong Middle Eastern influence and are also part of the Arab world.

The Sub-Saharan region is also known as Black Africa, in reference to its " black" populations, in contrast to the " Caucasoid" or " Melanochroi" inhabitants of North Africa. The term bilâd as-sûdân itself literally translates to "land of the blacks".

 

Geography

Sub-Saharan Africa covers an area of 24.3 million square kilometers.

Since around 5,400 years ago , the Saharan and sub-Saharan regions of Africa have been separated by the extremely harsh climate of the sparsely populated Sahara, forming an effective barrier interrupted by only the Nile River in Sudan, though the Nile was blocked by the river's cataracts. The Sahara Pump Theory explains how flora and fauna (including Homo sapiens) left Africa to penetrate the Middle East and beyond to Europe and Asia. African pluvial periods are associated with a "wetSahara" phase during which larger lakes and more rivers exist.

 

Climate zones and ecoregions

Southern Africa has a transition to semi-tropical ortemperate climates (green), and more desert or semi-arid regions, centered on Namibia and Botswana.

Sub-Saharan Africa has a wide variety of climate zones or biomes. South Africaand the Democratic Republic of the Congo in particular are consideredMegadiverse countries.

  • the Sahel cuts across all of Africa at a latitude of about 10° to 15° N. Contries that include parts of the Sahara proper in their northern territories and parts of the Sahel in their southern region include Mali, Niger, Chad andSudan.

History

East Africa

The distribution of the Nilo-Saharan linguistic phylum is evidence of a certain coherence of the central Sahara, the Sahel and East Africa in prehistoric times. Ancient Nubia appears to have acted as a link connecting Ancient Egypt to sub-Saharan Africa, based on traces of prehistoric south-to-north gene flow.Kush, Nubia at her greatest phase is considered sub-saharan Africa's oldest urban civialization. Nubia was a major source of gold for the ancient world. Accordingly, the Old Nubian language is itself a member of the Nilo-Saharan phylum. Old Nubian (arguably besides Meroitic) represents the oldest attested African language outside the Afro-Asiatic group.

The Axumite Empire spanned the southern Sahara and the Sahel along the western shore of the Red Sea. Located in northern Ethiopia and Eritrea, Aksum was deeply involved in the trade network between India and theMediterranean. Emerging from ca. the 4th century BC, it rose to prominence by the 1st century AD. It was succeeded by the Zagwe dynasty in the 10th century.

Somalia was under the control of Ethiopian Empire until 1527, when a revolt under Imam Ahmad ibn Ibrihim al-Ghazi led to an invasion of Ethiopia. The Ajuran dynasty ruled parts of East Africa from the 16th to 20th centuries.

Kenya's proximity to the Arabian Peninsula invited colonization, and Arab and Persian settlements sprouted along the coast by the 8th century. During the first millennium AD, Nilotic and Bantu-speaking peoples moved into the region, and the latter now comprise three-quarters of Kenya's population. In the centuries preceding colonization, the Swahili coast of Kenya was part of the east African region which traded with the Arab world and India especially for ivory and slaves. Swahili, a Bantu language with many Arabic, Persian and other Middle Eastern and South Asian loan words, developed as a lingua franca for trade between the different peoples.

In 1498 Vasco da Gama became the first European to reach the East African coast, and by 1525 the Portuguesehad subdued the entire coast. Portuguese control lasted until the early 18th century, when Arabs from Omanestablished a foothold in the region. Assisted by Omani Arabs, the indigenous coastal dwellers succeeded in driving the Portuguese from the area north of the Ruvuma River by the early 18th century.

West Africa

The Nok culture, known from a type of terracotta figure found in Nigeria, dating to 500 BC - AD 200.

There are a number of medieval kingdoms of the southern Sahara and the Sahel, based on trans-Saharan trade, including the Ghana Empire and the Mali Empire, Songhai Empire, the Kanem Empire and the subsequent Bornu Empire. The Benin Empire was a pre-colonial state of Nigeria (1440-1897).

The kingdoms of Ifẹ and Oyo in the western block of Nigeria became prominent about 700-900 and 1400 respectively. Another prominent kingdom in south western Nigeria was the Kingdom of Benin whose power lasted between the 15th and 19th century. Their dominance reached as far as the well known city of Eko which was named Lagos by the Portuguese traders and other early European settlers. In the 18th century, the Oyo and theAro confederacy were responsible for most of the slaves exported from Nigeria.

Following the Napoleonic wars, the British expanded trade with the Nigerian interior. In 1885 British claims to a West African sphere of influence received international recognition and in the following year the Royal Niger Company was chartered under the leadership of Sir George Taubman Goldie. In 1900 the company's territory came under the control of the British Government, which moved to consolidate its hold over the area of modern Nigeria. On January 1, 1901 Nigeria became a British protectorate, part of the British Empire, the foremost world power at the time.

Central Africa

The Bantu expansion has its original nucleus in West Africa, dividing into a Western and an Eastern Bantu group by about 1500 BC. The Eastern group has its nucleus at Urewe, in the first half of the 1st millennium BC. There follow a series of southwards advances, establishing a Congo nucleus by the end of the 1st millennium BC. In a final movement, the Bantu expansion reaches Southern Africa in the 1st millennium AD.

Southern Africa


Settlements of Bantu-speaking peoples, who were iron-using agriculturists and herdsmen, were already present south of the Limpopo River by the 4th or 5th century (see Bantu expansion) displacing and absorbing the originalKhoi-San speakers. They slowly moved south and the earliest ironworks in modern-day KwaZulu-Natal Province are believed to date from around 1050. The southernmost group was the Xhosa people, whose language incorporates certain linguistic traits from the earlier Khoi-San people, reaching the Fish River, in today's Eastern Cape Province.

Monomotapa was a medieval kingdom (c. 1250-1629) which used to stretch between the Zambezi and Limpopo rivers of Southern Africa in the modern states of Zimbabwe and Mozambique. It enjoys great fame for the ruins at its old capital of Great Zimbabwe.

In 1487, Bartolomeu Dias became the first European to reach the southernmost tip of Africa. In 1652, a victualling station was established at the Cape of Good Hope by Jan van Riebeeck on behalf of the Dutch East India Company. For most of the 17th and 18th centuries, the slowly-expanding settlement was a Dutch possession.Great Britain seized the Cape of Good Hope area in 1795 ostensibly to stop it falling into the hands of the French, but also seeking to use Cape Town in particular as a stop on the route to Australia and India. It was later returned to the Dutch in 1803, but soon afterwards the Dutch East India Company declared bankruptcy, and the British annexed the Cape Colony in 1806.

The Zulu Kingdom (1817-1879) was a Southern African state in what is now South Africa. The small kingdom gained world fame during and after the Anglo-Zulu War.

Demographics and economy


Generally, sub-Saharan Africa is the poorest region in the world, suffering from the effects of colonialism, economic mismanagement, local corruption. and inter-ethnic conflict. The region contains many of the least developed countries in the world. (See Economy of Africa.) The sub-Saharan African countries form the bulk of the ACP countries.

The population of sub-Saharan Africa was 770.3 million in 2006. The current growth rate is 2.3%. The UN predict for the region a population of nearly 1.5 billion in 2050.

Sub-Saharan African countries top the list of countries and territories by fertility rate with 40 of the highest 50, all with TFR greater than 4 in 2008. All are above the world average except South Africa. Figures for life expectancy,malnourishment, infant mortality and HIV/AIDS infections are also dramatic. More than 40% of the population of are below 15 years in most sub-Saharan countries, as well as the Sudan but with the exception of South Africa,.

Health care

In 1987, Bamako was the location of a WHO conference known as the Bamako Initiative that helped reshape the health policy of sub-Saharan Africa. The new strategy dramatically increased accessibility through community-based healthcare reform, resulting in more efficient and equitable provision of services. A comprehensive approach strategy was extended to all areas of health care, with subsequent improvement in the health care indicators and improvement in health care efficiency and cost.

Up to and including October 2006 many governments face difficulties in implementing policies aimed at mitigating the effects of the AIDS-pandemic due to lack of technical support despite a number of mitigating measures.

Languages and ethnic groups

Linguistically, sub-Saharan Africa is dominated by the Niger-Congo phylum (distribution shown in yellow), with pockets ofKhoi-San in Southern Africa,Nilo-Saharan in Central andEast Africa, and Afro-Asiatic in the Horn of Africa

Speakers of Bantu languages (part of the Niger-Congo family) are the majority in southern, central and east Africa proper. But there are also several Nilotic groups in East Africa, and a few remaining indigenous Khoisan (' San' or 'Bushmen') and Pygmy peoples in southern and central Africa, respectively. Bantu-speaking Africans also predominate in Gabon and Equatorial Guinea, and are found in parts of southern Cameroon and southern Somalia. In theKalahari Desert of Southern Africa, the distinct people known as the Bushmen (also "San", closely related to, but distinct from " Hottentots") have long been present. The San are physically distinct from other Africans and are the indigenous people of southern Africa. Pygmies are the pre-Bantu indigenous peoples of central Africa.

South Africa has the largest populations of whites, Indians and Coloured in Africa. The term " Coloured" is used to describe persons of mixed race in South Africa and Namibia. People of European descent in South Africa include theAfrikaner and a sizeable populations of Anglo-Africans and Portuguese Africans. Madagascar's population is predominantly of mixed Austronesian (Pacific Islander) and African origin. The area of southern Sudan is inhabited byNilotic people, the tallest and blackest people in the world.
