Economic history of Africa

The first agriculture in Africa began in the heart of the Sahara Desert, which in 5200 BC was far more moist and densely populated than today. Several native species were domesticated, most importantly pearl millet, sorghum and cowpeas, which spread through West Africa and the Sahel. The Sahara at this time was like the Sahel today. Its wide open fields made cultivation easy, but the poor soil and limited rain made intensive farming impossible. The local crops were also not ideal and produced fewer calories than those of other regions. These factors limited surpluses and kept populations sparse and scattered.

North Africa took a very different route from the southern regions. Climatically it is linked to the Middle East and the Fertile Crescent, and the agricultural techniques of that region were adopted wholesale. This included a different set of crops, such as wheat, barley, and grapes. North Africa was also blessed by one of the richest agricultural regions in the world in the Nile River valley. With the arrival of agriculture, the Nile region became one of the most densely populated areas in the world, and Egypt home to one of the first civilizations.

The drying of the Sahara created a formidable barrier between the northern and southern portions of the continent. Two important exceptions were Nubian Sudan, which was linked to Egypt by the Nile and Ethiopia, which could trade with the northern regions over the Red Sea. Powerful states grew up in these regions such as Kush in Nubia (modern day Northern Sudan and Southern Egypt) and Aksum in Ethiopia. Especially from Nubia, ideas and technologies from the Middle East and Europe reached the rest of Africa.

Historians believe that iron working developed independently in Africa. Unlike other continents Africa did not have a period of copper and bronze working before their Iron Age. Copper is quite rare in Africa while iron is quite common. In Nubia and Ethiopia, iron, trade, and agricultural surpluses lead to the establishment of cities and civilizations.

Ordinarily, in the sparsely populated areas, this same period saw the expansion of the Bantu speaking peoples. The Bantu expansion began in Southern Cameroon around 4000 years ago. Bantu languages are spoken there today and there is archaeological evidence for incoming Neolithic farmers in Northern Gabon c. 3800 BC. It is known that Bantu expansion was extremely rapid and massive, but its exact engine remains controversial. This period predated iron, which appears in the archaeological record by 2500 BC.

One of the early expansions of Bantu was the migration of the Bubi to Fernando Po (Bioko). They were still using stone technology at first. The difficulties of cutting down the equatorial forest for farming have led to the suggestion that the primary expansion was along river valleys, a hypothesis supported by studies of fish names. Another factor may have been the arrival of southeast-Asian food crops, notably the AAB plantain, the cocoyam and the water-yam. Linguistic reconstructions suggest that the only livestock possessed by the proto-Bantu was the goat. Over the centuries the entire southern half of Africa was covered with the group, excluding only the Kalahari desert. Their expansion only ended relatively recently. In the year 1000, Arab traders described that the Bantu had not reached as far as Mozambique[2], and European settlers observed the Bantu expansion into South Africa under the Zulu and others, yet there's no archaeological evidence that supports their claims instead on the contrary the evidence indicates Bantu speakers's presence very much earlier by over 1800 years and over 1400 years before the first European settlement in the south African regions of Mozambique and South Africa respectively.[3]

The importation Bantu pastoralism reshaped the continent's economy. Sometime in the first millennium, an equally important change began as crops began to arrive from Southeast Asia. The Indian Ocean has always been far more open to trade than the turbulent Atlantic and Pacific. Traders could ride the monsoon winds west early in the year and return east on them later. It is guessed that these crops first arrived in Madagascar, which also adopted Southeast Asian languages, sometime between AD 300 and 800. From the island, the crops crossed to African Great Lakes region. They included many crops, the most important being the banana.

The banana and other crops allowed for more intensive cultivation in the tropical regions of Africa, this was most notable in the Great Lakes region, an area with excellent soil, that saw many cities and states form, their populations being fed largely

Many wealthy empires grew around coastal areas or large rivers that served as part of important trade routes. The kingdoms of Mali and Songhai Empire grew along the Niger River between 1200 and 1590. Berber traders from the Sahel—a region south of the Sahara Desert—traded dates, copper, horses, weapons and cloth that they brought from north Africa in Camel trains.[5] Trade with the Berber people, and other groups, drove the growth of the Ghana empire, which traded its gold, kola nuts, and slaves. West Africans created a demand for salt, which was collected at desert oases, and which they used to preserve food as well as for seasoning it.[6]

In 1324, Mansa Musa, the king of Mali, made a historically famous Hajj (pilgrimage) to Mecca. There was an enormous group organized to undertake the Hajj with the king. It included "60,000 men, including 1200 servants" and records show that Mansa Musa gave out so much gold in Egypt, that its economy became depressed.[7]

Between 1000 and 1500, the forests of West Africa also became part of trade networks, particularly under the reigns of the Yoruba kings. Ifé was a vital trade town, along the route from the tropical forests to Djenné, a major trade centre in Sudan, near other large trade cities such as Timbuktu and Gao.[8] Ifé's location also placed it near Benin and the Atlantic Ocean. Yoruba civilization was supported by cities surrounded by farmed land, but extensive trade development made it wealthy.[9]

By 1000, the Bantu language-speaking people of Zimbabwe and Southern Africa developed extensive overseas trade with lands as far away as China and India, from which they received porcelain, beads, and Persian and Arab pots. They traded domesticated beef (rather than meat from game animals), iron, and ivory and gold.[10] The city of Great Zimbabwe, founded around 1100, was the centre of the Shona kingdom until around 1400.[11]

Much trade in the forest kingdoms was done at the local level, typically by ordinary Yoruba people at local markets. In some towns these were held every 3 or 4 days. Cloth, vegetables, meat, and other goods were traded, and paid for using small seashells called cowries which were imported from East Africa.[12] Bars of copper and iron, called manilas, were produced in standard shapes to be used as currency. Other items used in trade as a form of currency included salt, cloth, and bars of gold.[9]

Trade with the Middle East had begun as early as ancient Egypt. Islam was introduced to the Horn region early on from the Arabian peninsula, shortly after the hijra. Zeila's two-mihrab Masjid al-Qiblatayn dates to the 7th century.[13] The spread of Islam brought Arab traders as far as Morocco. The Adal Sultanate in the Horn region also maintained bilateral relations with the Ottoman Empire.[14] The institutional framework for long-distance trade across political and cultural boundaries had long been strengthened by the adoption of Islam as a cultural and moral foundation for trust among and with traders.[15] On the Swahili Coast to the southeast, the Sultan of Malindi sent envoys to the Chinese imperial palace in Nanjing Yongle bearing a giraffe and other exotic gifts.[16]

The earliest European colonists settled in North Africa in ancient times. These colonists included Phoenicians and Greeks. Settlers from ancient Athens and other parts of Greece established themselves along the Mediterranean coast of North Africa. They were later followed by colonists of the Roman Empire. Rome's colonies "served as a prototype" for later European colonial movement into the continent.[17]

Portugal was the first European empire to penetrate deep into Sub-Saharan Africa to establish colonies. Portuguese prince Henry the Navigator advanced Portuguese exploration of Africa, driven by two desires: to spread Christianity, and to establish Africa as a bastion of Christianity against the Ottoman Empire, which was making many African converts to Islam. Africa was exploited for commercial purposes because of another Portuguese goal: to find a route to India, which would open the entire Indian Ocean region to direct trade with Portugal. Conquest of territory in Africa also meant that the Portuguese could use African gold to finance travel along this new trade route.[18]

The Portuguese began significant trading with West Africa in the 15th century. This trade was primarily for the same commodities the Arabs had bought—gold, ivory, and slaves. The Portuguese sold the Africans Indian cloth and European manufactured goods but refused to sell them guns. Soon, however, other European powers such as France, Denmark, the Netherlands and Britain were developing their own trade with Africa, and they had fewer restrictions. The major European imperial powers in Africa were Portugal, Great Britain, France, and to a lesser extent Germany, Belgium, Spain and Italy. Portugal's presence in Africa as an imperial power lasted until the 1970s, when the last of its former colonies declared independence after years of war.

The Atlantic Ocean had long been all but impenetrable to the galleys that plied the Mediterranean. That any ship needed to pass thousands of kilometers of waterless desert before reaching any populated regions also made trade impossible. These barriers were overcome by the development of the caravel in Europe. Previously, trade with Sub-Saharan Africa could only be conducted through North African middlemen. Now Europeans could trade directly with the Africans themselves.

This valuable trade lead to rapid change in West Africa. The region had long been agriculturally productive and, especially in western Nigeria, densely populated. The massive profits from trade and the arrival of guns lead to significant centralization and a number of states formed in the region such as the Ashanti Confederacy and Kingdom of Benin. These states became some of the wealthiest and most advanced in Africa. Wealthy merchants began to send their children to European universities and their well armed standing armies could challenge European forces.

Many West-African natives, such as Seedies and Kroomen, served on European ships, and received regular pay, which greatly enhanced their status back home.

Clearly, the slave trade enriched the segments of African society that traded in slaves. However, the modern historiography of slavery has swung between two poles on the question of its demographic and economic effects on Africa as a whole. Early historical accounts of the Atlantic slave trade were largely written for a popular audience by abolitionists and former slaves like Olaudah Equiano who emphasized its profoundly negative effects on African peoples. As the 19th century progressed, accounts of the negative impact of slavery were increasingly used to argue for European colonization of the continent. Conversely, there were those, like the British explorer and geographer William Winwood Reade, who drew on the accounts of slave traders to argue that the effects of slavery were positive.[19]

By the early 20th century, the view of slavery as a negative influence on Africa prevailed among professional academic historians in Europe and the United States. During the decolonization period following World War II, an influential group of scholars, led by J.D. Fage, argued that the negative effects of slavery had been exaggerated, and that the export of slaves had been offset by population growth. Walter Rodney, a specialist on the Upper Guinea Coast, countered that European demand for slaves had vastly increased the economic importance of the slave trade in West Africa, with catastrophic effects. Rodney, who was active in Pan-African independence movements, accused Fage of whitewashing the role of Europeans in Africa; Fage responded by accusing Rodney of nationalist romanticism.[20]

Debates on the economic impacts of the Atlantic trade were further stimulated by the publication of Philip Curtin's The Atlantic Slave Trade: A Census (1969), which argued that 9.566 million slaves were exported from Africa through the Atlantic trade. In the 1970s, the debate on the economic impacts of the Atlantic trade increasingly turned on demographic estimates of slave exports in relation to continental birth rates. Most scholars now believe that Curtin was too conservative in his calculation, with most estimates ranging between 11.5 million to 15.4 million.[21] More recently, John K. Thornton has presented an argument closer to that of Fage, while Joseph Inikori, Patrick Manning and Nathan Nunn have argued that the slave trade had a long-term debilitating impact on African economic development.[22]

Manning, for example, arrived at the following conclusion, after accounting for regional variations in slave exports and assuming an annual African population growth rate of 0.5.%: the population of Africa would have been 100 million rather than 50 million in 1850, if not for the combined effects of the external and internal slave trades.[23] Nunn, in a recent econometric analysis of slave-exporting regions in all parts of Africa, found "a robust negative relationship between the number of slaves taken from a country and its subsequent economic development."[24] Nunn argues, moreover, that this cannot be explained by poverty prior to the slave trade, because more densely populated and economically developed parts of Africa regressed behind previously less developed, non-slave exporting areas during the course of the Atlantic, trans-Saharan, Red Sea and Indian Ocean slave trades.

The Berlin Conference (German: Kongokonferenz or "Congo Conference") of 1884–85 regulated European colonization and trade in Africa during the Imperialism period, and coincided with Germany's sudden emergence as an imperial power. Called for by Portugal and organized by Otto von Bismarck, first Chancellor of Germany, its outcome, the General Act of the Berlin Conference, can be seen as the formalization of the Scramble for Africa. The conference ushered in a period of heightened colonial activity by European powers, while simultaneously eliminating most existing forms of African autonomy and self-governance.[25] During this colonial time, the economy of Africa was re-arranged to serve Europe and Europeans, and the European industrial chain began in Africa and ended in European industrial warehouses.

All of Africa would ultimately fall under European colonial rule by 1914, with the exceptions of Ethiopia and Liberia.[26] The partitioning of African territory among European regimes often violated existing boundaries recognized by local Africans. Some of the independent African states affected by the partitioning of the continent included:[27]

Under colonial rule, the plantation system of farming was widely introduced in order to grow large quantities of cash crops, and employing cheap (often forced) African labor for export to European countries. Mining for gems and precious metals such as gold was developed in a similar way by wealthy European entrepreneurs such as Cecil Rhodes. The implementation and effects of these colonial policies could be brutal. One extreme example of exploitation of Africans during this period is the Congo Free State, administered under a form of "company rule". The Belgians, under Leopold II of Belgium, allowed businesses to use forced labour as they saw fit. The brutal conditions, famine and disease ended in the deaths of an estimated 10 million Congolese between 1885 and 1908.[28]

Belgian government commissions in the 1920s found that the population of Belgian Congo had fallen by as much as 50% under Congo Free State rule as a result of forced labor (largely for the purposes of rubber cultivation), massacre by colonial troops, famine and disease.[29] In white settler colonies like Algeria, Kenya, Rhodesia (now Zimbabwe), South Africa and Southwest Africa (now Namibia), the most fertile lands were forcibly expropriated from the indigenous populations for use by white settlers. In these countries African farmers were pushed onto "native reserves," usually located on arid, marginal lands. Slavery was also widely abolished by colonial powers.

To some colonizers, such as the British, the ideal colony was based on an open economy, actively engaged in world trade through the export of raw materials and the import of finished goods.[30] The British practiced a policy of light administration, enforcing relatively little regulation on their colonies, especially in non-economic matters. As long as British interests were achieved, native populations were given greater individual freedoms. However, other colonizers, such as the French, took a more active approach to governance, encouraging or even requiring their subjects to more fully assimilate into French culture.[31]

Colonizers were under heavy political pressure to make their colonies immediately and continuously profitable. In almost all cases, this constraint led to a shortage of long-term investment from the mother countries into the economic development in their colonies. While these countries did finance some major infrastructure projects designed to facilitate trade, this was primarily to aid in the immediate extraction of valuable resources, and there was little to no investment into growing local business. Another reason colonial governments allowed local economies to lag behind was that competitive local industries would have reduced the colonies’ trade dependence on the central economies in Europe.

For the colonies to be integrated into the world economy and imperial trade network, the colonial governments needed the local citizens to engage in market activity, rather than simply subsistence agriculture. One method that colonial powers used to urge the native populations into participating in the larger economy was the requirement that taxes be paid in official currency. This made subsistence farming less feasible, as the producers then needed to sell at least some surplus in the market to obtain the currency needed for the payment of taxes.[32]

Many times colonial powers collected these taxes through the assistance of local African chiefs, who were politically and financially supported by the colonial governments in exchange for their assistance in enforcing these governments’ policies, especially for policies that could be unpopular. Thus, the colonizers themselves avoided some degree of animosity from their subjects by using these established chiefs as proxies to enforce many of their coercive policies.

Today, many African economies are affected by the legacy of colonialism. In agriculture, the plantation systems that they introduced were highly unsustainable and caused severe environmental degradation. For example, cotton severely lowers soil fertility wherever it is grown, and areas of West Africa that are dominated by cotton plantations are now unable to switch to more profitable crops or even to produce food because of the depleted soil. Recently, more countries have initiated programs to change to traditional, sustainable forms of agriculture such as shifting cultivation and bush fallow in order to grow enough food to support the population while maintaining soil fertility which allows agriculture to continue in future generations.
