7.1 Introducing the Realm

Physical Geography of Subsaharan Africa

The African Transition Zone divides North Africa from the rest of Africa because of climatic and cultural dynamics. Cultural conflicts and desertification are common in the zone. Dry, arid type B climates, common in the Sahara Desert, are dominant north of the zone. Tropical type A climates prevail south of the zone. Global climate changes continue to shape the continent. The shifting sands of the Sahara are slowly moving southward toward the tropics. Desertification in the zone continues as natural conditions and human activity place pressure on the region through overgrazing and the lack of precipitation. Type B climates resurface again south of the tropics in the southern latitudes. The Kalahari and Namib Deserts are located in Southern Africa, mainly in the countries of Botswana and Namibia.

For a continent as large as Africa, Subsaharan Africa does not have extended mountain ranges comparable to the ranges in North or South America, Europe, Asia, or Antarctica. There are, however, on the Ethiopian Highlands the Ethiopian Plateau that reach as high as 15,000 feet in elevation. East Africa has a number of well-known volcanic peaks that are high in elevation. The tallest point in Africa—Mt. Kilimanjaro in Tanzania near the border with Kenya—is 19,340 feet high. Nearby in Kenya, Mt. Kenya is 17,058 feet high. The Rwenzori Mountains on The Congo/Uganda border reach more than 16,000 feet in elevation and create a rain shadow effect for the region. Permanent glaciers exist on these ranges even though they are near the equator. On the western side of the continent, Mt. Cameroon in Central Africa is more than 13,000 feet in elevation. South Africa’s Cape Ranges are low-lying mountains no higher than about 6,000 feet. The continent of Africa consists of basins and plateaus without long mountain chains. The plateaus can range more than 1,000–2,500 feet in elevation. The only continuous feature is the eastern rift valleys that run along the tectonic plate boundaries from the Red Sea through to South Africa.

The main rivers of Africa include the Nile, Niger, Congo, and Zambezi. The Nile River competes with the Amazon for the status as the longest river in the world; the White Nile branch begins in Lake Victoria in East Africa, and the Blue Nile branch starts in Lake Tana in Ethiopia. The Niger flows through West Africa; its mouth is in Nigeria. The Congo River crosses the equator with a large tropical drainage basin that creates a flow of water second only to the Amazon in volume. The Zambezi River in the south is famous for the extensive Victoria Falls on the Zambia and Zimbabwe border. Victoria Falls is considered the largest waterfall in the world. Other significant rivers exist such as the Orange River, which makes up part of the border between South Africa and Namibia.

There are a number of large lakes in Subsaharan Africa. The largest is Lake Victoria, which borders several East African countries and is considered to be the second-largest lake in the world in surface area. Only Lake Superior in North America has a greater surface area. A number of large lakes are located in the rift valleys of the east. Three of the largest lakes along the western rift are Lake Malawi, Lake Tanganyika, and Lake Albert. To the northeast of these in Kenya is Lake Turkana, which reaches to the Ethiopian border. Lake Chad is located in the African Transition Zone on the border between Chad, Mali, and Nigeria. Lake Chad has been severely reduced in size in recent years.

The equator runs through the center of Subsaharan Africa, providing tropical type A climates. These regions usually have more rainfall, resulting in lighter, leached-out soils that may not be as productive as regions with richer volcanic soils, such as those found in the rift valleys. Root crops are common in Africa, as are millet and corn (maize). The savanna regions of the east and south have seasonal rains that affect the growing season. Soils in savanna areas are usually not as productive and cannot be depended on to fulfill the agricultural needs of growing populations. Savannas are usually grasslands or scrub forests with a seasonal precipitation pattern. Cattle and livestock grazing are common in savannas, and migrations are frequent to follow seasonal grazing conditions. In specific areas of Southern Africa, larger farming operations exist in type C climates. However, Subsaharan Africa is not blessed with the large regions of rich alluvial soils found in the Northern Hemisphere. The ever-growing agrarian population has always depended on the land for food and sustenance, but these conditions are not favorable for Africa’s future. Populations are growing faster than any increase in agricultural production.

Increasing populations in Subsaharan Africa are taxing the natural environment. Where the carrying capacity has been exceeded, the natural capital is being depleted at an unsustainable rate. Deforestation is occurring in areas where firewood is in high demand, and trees are cut down faster than they can grow back. Expanding human populations are also encroaching on the natural biodiversity for which the African continent is renowned. Large game animals such as rhinoceroses, elephants, and lions have been hunted or poached with devastating consequences. The creation of game preserves and national parks has stemmed this tide, but poaching remains a serious problem even in these protected areas. Gorilla and chimpanzee populations have also been stressed by human population growth. These animals are being killed by humans for bush meat, and their habitats are being reduced by human activities.

Perhaps the largest ecoregion of Subsaharan Africa is the Sahel, located just south of the Sahara. The Sahel is a transitional region connecting the dry Sahara to the tropical regions of the south. It is mostly grassland and has traditionally supported semi-nomadic livestock herders. The Sahel is at the front line of one of the most pressing environmental concerns in Africa: desertification (see Figure 6.5). Desertification refers to the process of previously fertile land becoming desert and occurs for a variety of reasons including climate change and human activities. Overgrazing, for example, can rid land of vegetation causing the erosion of fertile topsoil. Warming temperatures due to global changes in climate can change precipitation patterns and increase the speed of evaporation. Desertification in the Sahel has caused the Sahara to expand and has led to conflict as northern farmers have migrated to the south in search of fertile soil.

Kingdoms, Empires, and the Slave Trade

Pre-colonial Africa was also the site of a number of large empires (see Figure 6.6). The Kingdom of Kush, for example, was established in 1070 BCE and located on the Nile River just south of the Egyptian Empire. The Kingdom of Aksum located in present-day Eritrea and Ethiopia existed from 100 CE to 940 CE and was one of the most powerful of the pre-colonial African empires. The rulers of the kingdom minted their own currency, built religious monuments, and established trading routes. The first state in West Africa was the Empire of Ghana, which lasted from around 350 CE until its conquest by the Mali Empire in the 1200s CE. The Empire of Ghana had a large capital city, markets, and a system of taxation.

West Africa was home to a number of large empires that shaped the culture and people of present-day Africa. Gold, salt, copper, and ivory were important early trading commodities. Mining and acquiring these items brought enormous wealth to the region. Slavery became a component in the warfare between groups, as the winner usually took the captives to serve as servants or slaves. The Ghana Empire (790–1076 CE) was responsible for one of the early consolidations of power in West Africa. Though its power and wealth were vast, it was only the first of a number of empires to arise in the region.

After the Ghana Empire came the Mali Empire (1230–1600 CE), which was known for its wealth and size. The empire held major mining operations including gold, copper, and salt. Expanding along the Niger River and to the Atlantic coast, the Mali Empire extended over an area the size of Western Europe. Originally a federation of local groups, the empire incorporated many smaller provinces or kingdoms and had a major influence on the region’s laws and cultural heritage.

Figure 7.6 Empires of West Africa

One of the indigenous states that evolved out of the Mali Empire was that of the Songhai people, who were located to the east of the main Mali Empire. The Songhai had been based around the city of Gao for centuries, and in the fifteenth century, they established the Songhai Empire, one of the largest empires in African history. The city of Timbuktu became prominent during this period as an urban center, and its educational institutions became well known. In the end, the Songhai Empire was defeated by Moroccan Berber forces that splintered the empire into many smaller kingdoms and ethnic clans.

South of the empires of the Niger River were coastal kingdoms, including the Ashanti and the Dahomey, which flourished during the colonial era. The local African groups had to contend with the colonial European traders and invaders, which had superior weapons and different technology. Besides the mining resources of gold copper, salt, and ivory, the slave trade was a driving force that attracted trade ships from various European countries.

The Ashanti Empire was located along the Atlantic coast in an inland region of what is now Ghana and Ivory Coast; this area served as a trading corridor where goods from the northern regions crossed to make their way to the coastal trading towns. The Ashanti Empire took advantage of the trade opportunities and became wealthy. By the time the Europeans arrived, Ashanti trade relationships were well established and capable of supplying the colonial ships with slaves, ivory, and gold. The coastal area of Ghana was known as the Gold Coast during colonial times. Similarly, the country of Ivory Coast (Côte d’Ivoire) got its name from its participation in the elephant ivory trade. The Ashanti were known for their involvement in the slave trade and today must live with that legacy.

This region of West Africa bordering the Atlantic was called the Slave Coast because of the high number of local people from this area who were sold into the European slave trade and shipped to the Americas. The once powerful Kingdom of Dahomey, east of the Ashanti Empire, was heavily involved in the slave trade. Slave trading with Europeans brought them rifles and other firearms that were useful in conflicts with their regional adversaries. A major slave state along the Slave Coast, the kingdom attracted the spite of its neighbors as a pariah state for selling its war captives into transatlantic slavery rather than killing them, as was the custom in warfare. The Kingdom of Dahomey became the country of Benin after the colonial era.

The slave trade brought wealth to many of the slave-trading kingdoms on the African coast. The demand for slaves pushed many of the African kingdoms to expand their slave-trading activities, capturing more individuals whom they could sell to European slave traders. Millions of Africans were captured by other Africans only to be sold into slavery, placed on ships, and sent to slave owners in the Americas. The total number sold into the Atlantic slave trade will never be known, but estimates range somewhere between ten and twelve million.

States and kingdoms existed throughout Subsaharan Africa. Early kingdoms flourished in the region that is now Ethiopia. East Africa’s Axum Empire was an example of the powers of the early African savanna kingdoms located in the east. The struggles between Islam and Christianity divided the region and gave way to the African Transition Zone, which serves as the dividing line between the two religions. Ethiopia has retained its Christian heritage, while to the north and east Islam has prevailed. South of the equator, the ruins of Great Zimbabwe give testimony to the regional base of power that existed there in centuries past. The Zulu Empire thrived in the nineteenth century in the region that is now South Africa.

Colonialism in Subsaharan Africa

Wherever you go in the world, you cannot escape the impact of European colonialism. Subsaharan Africa was broadly affected by colonial activities, the legacy of which can be recognized to this day. Colonial powers of Europe ventured into Africa to claim colonies. In the discussion on Brazil in chapter 6 “South America,” section 6.3 “Brazil,” there is a segment on slavery and the Trade Triangle of the North Atlantic. Slavery impacted Africa in other ways. Many African groups were instrumental in capturing and holding slaves to trade with the European merchants. These groups still exist and have had to live with the fallout of their role in the supply side of the slave trade.

As the Industrial Revolution was spreading across Europe, colonial empires were seeking to expand their colonial holdings in order to gain mineral resources and expand agricultural production. As Europeans began exploring the interior of Africa, and recognized its resource potential, competition among European empires grew fierce. France, Italy, Britain, Portugal, and Belgium all raced through the interior of Africa trying to expand and strengthen their territories. When Germany entered the race, the colonial empires decided that it was in Europe’s best interest to agree on and clearly demarcate African colonies and to agree on common policy.

By 1900, European colonial powers claimed most of Africa. Only the Kingdom of Ethiopia and the area of Liberia, which was established as a home for freed slaves, remained independent. In 1884, Otto von Bismarck of Germany hosted the Berlin Conference, which to a great degree determined how Africa was colonized. This conference included fourteen colonial European countries and the United States, and its purpose was to divide Africa and agree on colonial boundary lines. Germany had few claims in Africa; Bismarck was hoping to benefit by playing the other countries against each other. At the time, more than 80 percent of Africa remained free of colonial control. On a large map of Africa, claims were argued over and boundary lines were drawn according to European agreements.

European colonization of Africa completely reshaped the political and ethnic landscape, with lasting effects even today. Colonialism broadly refers to the control of a territory by another group and colonial policies varied across Africa. In the Belgian Congo, what is now the Democratic Republic of the Congo, there was a racist ideology of paternalism where Africans were essentially viewed as children needing a fatherly, or paternal, authority to educate them in the ways of the West. In the far-reaching French colonies, from present-day Madagascar to Morocco, the colonizers emphasized an assimilationist policy, spreading the French culture through language, laws, and education. In the British colonies, like present-day Uganda, Ghana, and Nigeria, settlers partnered with local rulers who were made representatives of the British crown. This was known as indirect rule. The Portuguese, however, continued to be primarily interested in resources rather than local politics or culture. Their policy of exploitation in places like Angola and Mozambique ignored local development and the empire kept rigid control over local economies.

There was little regard for the concerns of local ethnic groups. Colonial boundaries divided close-knit communities into separate colonies. Ethnic boundaries were disregarded. Often-warring groups were placed together in the same colony. The Europeans, seeking profits from cheap labor and resources, did not consider the local people or culture and often employed brutal measures to subdue the local people. Most of the current borders in Africa are a result of the Berlin Conference, and many of the geopolitical issues that confront Africa today can be traced back to this event specifically and to colonialism in general. Many of the political and economic challenges facing the countries in contemporary Africa are rooted in its colonial history.

European colonizers were generally focused on exporting goods, with little attention given to local development or connectivity. These easily sold raw materials or agricultural goods are known as commodities. Local communities that may have previously practiced subsistence agriculture were shifted to produce export-oriented crops destined for European markets. When rail lines were built in Africa, they were generally constructed to simply take resources from the interior to the coastal ports without concern for developing regional linkages.

European colonialism remained strong in Africa until the end of World War II, which left many European countries economically exhausted. In 1945, the United Nations (UN) was established. One of the primary UN objectives was to oversee the decolonization of European colonies. Still, colonialism in Subsaharan Africa lingered on. It was not until the 1990s that the last colony was finally freed. The transition from colony to independent nation itself caused conflict. Civil wars were fought over who would control the country after the Europeans were pushed out. The transition to full independence has exacted a heavy toll from African countries but has resulted in stronger political structures and greater democratic liberties in many cases. The first country to gain independence in Subsaharan Africa was Ghana in 1957.

Figure 7.8 Colonialism in Africa

During the era of independence after World War II, the Cold War between the United States and the Soviet Union enticed many of the African countries to support one or the other of the superpowers. The political pressure that divided African countries during the Cold War has persisted and is the basis of some of the current political problems. The European countries extracted raw materials and minerals from their African colonies as well as slave labor. Varying degrees of attention were given to education, medical care, and infrastructure development. The dependency that a colony had on a European country for economic income in some cases continued long after independence and may still continue today. On the other hand, major technology transfers from Europe to Africa infused greater efficiencies into Africa’s economic activities. The imperial nature of colonialism and the divisive Cold War did bring about, in an unfortunate manner, the benefits of structured governments and greater democratic processes for many of the local areas of the realm.

From Colonialism to Independence

Figure 7.10 Freedom Square in Ghana

The transition from European colony to independent state has not necessarily been a civil transition for African countries; likewise, independent African countries have struggled to create stable governments or peaceful conditions—though stable governments and peaceful conditions have been established in some cases. In nearly all cases, removing the colonial powers from Africa was only half the battle toward independence. The other half was establishing a functional, effective government.

Though each country has taken a slightly different path, most former colonies have endured civil unrest, conflict, or warfare in their push for stable governments. Coups, fraudulent elections, military regimes, and corruption have plagued the leadership in a number of African countries. Civil unrest usually precedes a change in leadership; political power regularly changes hands by a military coup or an overthrow of the current leader.

The realm has had difficulty developing and maintaining effective political systems with democratic leadership. Political leaders have come and gone, many have been replaced before their terms were over, and a few have stayed long after their terms ended. When a leader is elected democratically, it is common to have widespread accusations of corruption, voter fraud, or ballot box scandals. Such government mismanagement and corruption have been common problems.

The vacuum left by retreating colonial powers at times has been filled by authoritarian dictators or by leaders who assumed control of the government and then proceeded to pillage and plunder the state for personal gain or for the enrichment of their clan or political cronies. After the colonial era, it was not uncommon for new leaders to be connected to the old colonial power and to adopt the language and business arrangements of the European colonizer. This gave them an advantage over their competitors and provided a means of income gained by the support of their former European colonial business partners, which often wanted to keep ties with their colonies to continue to exploit their resources for economic profits. Many of these leaders stayed in power because of military backing or authoritarian rule funded by the profits from selling minerals or resources to their former colonial masters.

A few countries are still struggling to bring about some type of order and unity, and in spite of all the negative issues, there have been democratic and relatively stable progressive governments in Africa that have emerged from the transition in recent years, which is a hopeful trend for the long term.

It is important to note that the objective of colonialism was to connect a colony with the mother country, not to connect African countries to each other. As a result, little cooperation occurs between African countries. Each individual country interacts more with its European colonial counterpart with regard to trade, economics, and cultural dynamics. European colonialism has isolated African countries from their neighboring countries and does not contribute to unity within or among African regions. Colonial powers often built new port cities to extract goods and resources from their colonies and transportation systems from the new ports to the interior to collect the resources and bring them to the port. However, the colonial powers did not build a network of transportation systems that connected the region as a whole. Colonial powers were intent on continuing dependence on the mother country so their colonies could be controlled and dominated.

The current wave of globalization based on corporate colonialism continues to encourage the same pattern of discouraging interaction between countries and instead encouraging trade with more economically powerful non-African countries. Most of the interaction between countries is a result of crisis or warfare, in which case large numbers of refugees cross the border into neighboring countries for personal survival or security. To begin to work together and promote trade, common transportation, security, and industry, fifteen West African states came together in 1975 to create the Economic Community of West African States (ECOWAS). Since then, additional political and economic agreements have been signed by various African countries. In 2001, the more expansive African Union was created to help African states compete in the international marketplace.
