A participant in the International Military Education and Training program, he received training "at training programmes in

188-637: A Berber language, in which "gher" means "watercourse", confusion could easily arise. Pliny connected these two rivers as one long watercourse which flowed (via lakes and underground sections) into the Nile, a notion which persisted in the Arab and European worlds – and further added the Senegal River as the "Ger" – until the 19th century. While the true course of the Niger was presumably known to locals, it

The area's climate and ecology are heavily influenced by the dry Sahara to the north and east, which provides dry winds during the Harmattan , as well as the Atlantic Ocean to the south and west, which provides seasonal monsoons. This mixture of climates gives West Africa a rich array of biomes , from biodiversity-rich tropical forests to drylands supporting rare and endangered fauna such as pangolins , rhinoceros , and elephants . Because of

752-554: A subgroup of the Igbo people. The Kingdom of Nri was unusual in the history of world government in that its leader exercised no military power over his subjects. The kingdom existed as a sphere of religious and political influence over a third of Igboland and was administered by a priest-king called an Eze Nri . The Eze Nri managed trade and diplomacy on behalf of the Nri people and possessed divine authority in religious matters. The Oyo Empire

In West Africa, as in other parts of Africa where the baobab tree is found, the leaves are mixed with couscous and eaten, the bark of the tree is used to make ropes, and

1598-597: Is the Benue River . The Niger has different names in the different languages of the region: The earliest use of the name "Niger" for the river is by Leo Africanus in his Della descrittione dell’Africa et delle cose notabili che ivi sono , published in Italian in 1550. Nevertheless, "Nigris" was already the name of a river in West Africa, as mentioned by Pliny the Elder and Solinus, among others. Whether this river

1692-633: The African slave trade began not long after, which over the following centuries would debilitate the region's economy and population. The slave trade also encouraged the formation of states such as the Bono State , Bambara Empire and Dahomey , whose economic activities include but not limited to exchanging slaves for European firearms . In the early 19th century, a series of Fulani reformist jihads swept across Western Africa. The most notable include Usman dan Fodio 's Fulani Empire , which replaced

1786-560: The Benue Trough , and others on a line running from Mount Cameroon to Lake Chad . Colonial boundaries are reflected in the modern boundaries between contemporary West African states, cutting across ethnic and cultural lines, often dividing single ethnic groups between two or more states. In contrast to most of Central, Southern, and Southeast Africa, West Africa is not populated by Bantu -speaking peoples. The West African region can be divided into four climatic sub-regions namely

1880-727: The Hausa city-states, Seku Amadu 's Massina Empire , which defeated the Bambara, and El Hadj Umar Tall 's Toucouleur Empire , which briefly conquered much of modern-day Mali. However, the French and British continued to advance in the Scramble for Africa , subjugating kingdom after kingdom. With the fall of Samory Ture's established Wassoulou Empire in 1898 and the Ashanti queen Yaa Asantewaa in 1902, most West African military resistance to colonial rule resulted in failure. Part of

2068-536: The Scramble for Africa at the end of the 19th century. As part of the West Africa Sahel region, Niger River has a hot climate characterized by very high temperatures year-round; a long, intense dry season from October–May; and a brief, irregular rainy season linked to the West African monsoon. The Niger River is a relatively clear river, carrying only a tenth as much sediment as the Nile because

2162-751: The Senegambia region (Senegal and the Gambia) used to have a diverse wildlife including lions , hippopotamus , elephants , antelopes , leopards etc. However, during colonization, the European colonizers such as the French and British killed most of the wildlife particularly the lions, using their body parts as trophies. By the turn of the 20th century, the Senegambia region had lost most of its lion population and other exotic animals due to poaching . By

2256-588: The Wadi Ghir on the north-western edge of the Tuat , along the borders of modern Morocco and Algeria . This would likely have been as far as Ptolemy would have had consistent records. The Ni-Ger was likely speculation, although the name stuck as that of a river south of the Mediterranean's "known world". Suetonius reports Romans traveling to the "Ger", although in reporting any river's name derived from

2350-459: The forest-savanna region, were ultimately acculturated and admixed into the larger groups of West African agriculturalists , akin to the migratory Bantu -speaking agriculturalists and their encounters with Central African hunter-gatherers . The development of the region's economy allowed more centralized states and civilizations to form, beginning with Dhar Tichitt that began in 1600 B.C. followed by Djenné-Djenno beginning in 300 B.C. This

2444-560: The population history of West Africa . Acheulean tool-using archaic humans may have dwelled throughout West Africa since at least between 780,000 BP and 126,000 BP ( Middle Pleistocene ). During the Pleistocene , Middle Stone Age peoples (e.g., Iwo Eleru people , possibly Aterians ), who dwelled throughout West Africa between MIS 4 and MIS 2 , were gradually replaced by incoming Late Stone Age peoples , who migrated into West Africa as an increase in humid conditions resulted in

2538-576: The 10th-century Kingdom of Nri , which helped birth the arts and customs of the Igbo people , Bono State in the 11th century, which gave birth to the numerous Akan States, while Ife rose to prominence around the 12th century. Further east, Oyo arose as the dominant Yoruba state and the Aro Confederacy as a dominant Igbo state in modern-day Nigeria. The Kingdom of Nri was a West African medieval state in present-day southeastern Nigeria and

The modern nations of Nigeria and Niger take their names from the river, marking contesting national claims by colonial powers of the "upper", "lower" and "middle" Niger river basin during

2820-494: The 1930s, the Gambian elephant population became extinct. That phenomenon was not only limited to the Senegambia region but affected much of West Africa as the region lost much of its "natural resources once tied so closely to its cultural identity. Poaching has stolen most of its wildlife." The British issued poaching licenses, and although they would later try to reverse the damage that had been done by attempting to preserve what

2914-418: The 1950s. Some have identified the two recent decades as a recovery period. Others refer to this as a period of "hydrological intensification" with much of the annual rainfall increase coming from more severe rain events and sometimes flooding rather than more frequent rainfall, or similarly other works underline the continuity of the drought even though the rainfall has increased. Since 1985, 54 percent of

3008-592: The 1980s. The Niger takes one of the most unusual routes of any major river, a boomerang shape that baffled geographers for two centuries. Its source ( Tembakounda ) is 240 km (150 mi) inland from the Atlantic Ocean, but the river runs directly away from the sea into the Sahara Desert , then takes a sharp right turn near the ancient city of Timbuktu and heads southeast to the Gulf of Guinea . This strange geography apparently came about because

3102-615: The Atlantic. Due to Mauritania's increasingly close ties to the Arab World and its 1999 withdrawal from the Economic Community of West African States (ECOWAS), in modern times it is often considered, especially in Africa, as now part of western North Africa . Major and principal cities in West Africa include, geographically eastward: Before European colonisation , West African countries such as those from

A Trans-ECOWAS project, established in 2007, plans to upgrade railways in this zone. One of the goals of the Economic Community of West African States (ECOWAS) is the development of an integrated railroad network. Aims include the extension of railways in member countries,

3290-684: The Guinea Coast, Soudano-Sahel, Sahel (extending eastward to the Ethiopian border) and the Sahara, each with different climatic conditions. The seasonal cycle of rainfall is mainly driven by the south-north movement of the Inter-Tropical Convergence Zone (ITCZ) which is characterised by the confluence between moist southwesterly monsoon winds and the dry northeasterly Harmattan. Based on the inter-annual rainfall variability, three main climatic periods have been observed over

The average loss is estimated at 31 km /year but varies considerably between years. The river is then joined by various tributaries but also loses more water to evaporation. The quantity of water entering Nigeria

3478-654: The Interior of Africa . Park proposed a theory that the Niger and Congo were the same river. Although the Niger Delta would seem like an obvious candidate, it was a maze of streams and swamps that did not look like the head of a great river. He died in 1806 on a second expedition attempting to prove the Niger-Congo connection. The theory became the leading one in Europe. Several failed expeditions followed; however

3572-625: The Ivory Coast, have lost large areas of their rainforest . In 2005, the Food and Agriculture Organization of the United Nations ranked Nigeria as the state with the worst deforestation rate in the entire world. Causes include logging, subsistence agriculture , and the collection of fuelwoods. According to a ThoughtCo publication authored Steve Nix (2018), almost 90 percent of West Africa's original rainforest has been destroyed, and

After having persisted as late as 1000 BP, or some period of time after 1500 CE, remaining West African hunter-gatherers, many of whom dwelt in

3854-467: The Niger River is two ancient rivers joined together. The upper Niger, from the source west of Timbuktu to the bend in the current river near Timbuktu , once emptied into a now dry lake to the east northeast of Timbuktu, while the lower Niger started to the south of Timbuktu and flowed south into the Gulf of Guinea. Over time upstream erosion by the lower Niger resulted in stream capture of the upper Niger by

3948-428: The Niger bend region also brought Islam to the region in approximately the 14th century CE. Much of the northern Niger basin remains Muslim today, although the southern reaches of the river tend to be Christian. Classical writings on the interior of the Sahara begin with Ptolemy , who mentions two rivers in the desert: the "Gir" (Γειρ) and farther south, the "Nigir" (Νιγειρ). The first has been since identified as

The irrigation potential was estimated at 1.68m ha in Nigeria 0.56m ha in Mali, and the actual irrigated area was 0.67m ha and 0.19m ha. West Africa West Africa , also called Western Africa , is the westernmost region of Africa . The United Nations defines Western Africa as

4136-633: The Niger's headwaters lie in ancient rocks that provide little silt . Like the Nile, the Niger floods yearly; this begins in September, peaks in November, and finishes by May. An unusual feature of the river is the Inner Niger Delta , which forms where its gradient suddenly decreases. The result is a region of braided streams , marshes , and large lakes; the seasonal floods make the Delta extremely productive for both fishing and agriculture. The river loses nearly two-thirds of its potential flow in

4230-597: The Sahel: the wet period from 1950 to the early 1960s followed by a dry period from 1972 to 1990 and then the period from 1991 onwards which has seen a partial rainfall recovery. During the dry period, the Sahel experienced a number of particularly severe drought events, with devastating effects. The recent decades, have also witnessed a moderate increment in annual rainfall since the beginning of 1990s. However, total annual rainfall remains significantly below that observed during

4324-567: The Sahelian region resulted in seasonal interaction with and gradual absorption of West African hunter-gatherers, who primarily dwelt in the savannas and forests of West Africa. In West Africa, which may have been a major regional cradle in Africa for the domestication of crops and animals, Niger-Congo speakers domesticated the helmeted guineafowl between 5500 BP and 1300 BP; domestication of field crops occurred throughout various locations in West Africa, such as yams (d. praehensilis) in

He also studied English language at Lackland Air Force Base in Texas. His first actions as de facto head of state included suspending the constitution and activities of some organizations, as well as declaring a curfew and closing

4512-453: The West African regions underwent an increase in the numeracy level throughout the 19th century. The reason for such a growth was predetermined by a number of factors. Namely, the peanut production and trade, which was boosted by the demand of the colonial states . Importantly, the rise of numeracy was higher in the regions which were less hierarchical and had less dependence on the slavery trade (e.g. Sine and Salum). Whereas areas with

The UN region also includes the United Kingdom Overseas Territory of Saint Helena, Ascension and Tristan da Cunha in

5546-626: The end of the African humid period around 5,500 years before present, the modern Sahara Desert, once a savanna , underwent desertification . As plant species sharply declined, humans migrated to the fertile Niger River bend region, with abundant resources including plants for grazing and fish. Like in the Fertile Crescent , many food crops were domesticated in the Niger River region, including yams , African rice ( Oryza glaberrima ), and pearl millet . The Sahara aridification may have triggered, or at least accelerated, these domestications. Agriculture, as well as fishing and animal husbandry, led to

6956-447: The region through colonial relationships . For example, they continued exporting a number of extractive goods , including labor-intensive agricultural crops like cocoa and coffee , forestry products like tropical timber , and mineral resources like gold. Since independence, many West African countries, like Ivory Coast , Ghana , Nigeria and Senegal , have played important roles in the regional and global economies. West Africa has

7050-521: The region's wildlife populations, there are still some protected nature reserves within the region. Some of these include: West Africa is also home to several baobab trees and other plant life . Some baobab trees are several centuries old and form part of the local folklore, for example, a mythical baobab tree named Ngoye njuli in Senegal which is regarded as a sacred site by the Serer . The tree itself

7144-453: The rest is "heavily fragmented and in a degraded state, being poorly used." Overfishing is a major issue in West Africa. Besides reducing fish stocks in the region, it also threatens food security and the livelihoods of many coastal communities that largely depend on artisanal fishing . The overfishing generally comes from foreign trawlers operating in the region. To combat the overfishing, Greenpeace has recommended countries reduce

7238-504: The rise of settlements like Djenné-Djenno in the Inner Delta, now a World Heritage Site . The region of the Niger bend, in the Sahel , was a key origin and destination for trans-Saharan trade , fueling the wealth of great empires such as the Ghana , Mali, and Songhai Empires . Major trading ports along the river, including Timbuktu and Gao, became centers of learning and culture. Trade to

7332-410: The river Niger. As Timbuktu was the southern end of the principal Trans-Saharan trade route to the western Mediterranean , it was the source of most European knowledge of the region. Medieval European maps applied the name Niger to the middle reaches of the river, in modern Mali, but Quorra ( Kworra ) to the lower reaches in modern Nigeria , as these were not recognized at the time as being

7426-692: The river – the myth connecting the Niger to the Nile persisted. Many European expeditions to plot the river were unsuccessful. In 1788 the African Association was formed in England to promote the exploration of Africa in the hopes of locating the Niger, and in June 1796 the Scottish explorer Mungo Park was the first European to lay eyes on the middle portion of the river since antiquity (and perhaps ever). He wrote an account in 1799, Travels in

7520-736: The same regions (e.g., Djado , Acacus , Tadrart ). Hunters in the Central Sahara farmed, stored, and cooked undomesticated central Saharan flora , underwent domestication of antelope , and domesticated and shepherded Barbary sheep . After the Kel Essuf Period and Round Head Period of the Central Sahara, the Pastoral Period followed. Some of the hunter-gatherers who created the Round Head rock art may have adopted pastoral culture, and others may have not. As

7614-474: The same river. When European colonial powers began to send ships along the west coast of Africa in the 16th and 17th centuries, the Senegal River was often postulated to be the seaward end of the Niger. The Niger Delta, pouring into the Atlantic through mangrove swamps and thousands of distributaries along more than 160 kilometres (100 mi), was thought to be coastal wetlands. It was only with

7708-848: The south Atlantic Ocean . In the United Nations scheme of African regions , the region of Western Africa includes 16 states and the United Kingdom Overseas Territory of Saint Helena, Ascension and Tristan da Cunha : Mali , Burkina Faso , Senegal and the Niger are mostly in the Sahel , a transition zone between the Sahara desert and the Sudanian Savanna ; Benin , Ivory Coast , The Gambia , Ghana , Guinea , Guinea-Bissau , Liberia , Sierra Leone , Togo and Nigeria compose most of Guinea ,

7802-538: The subsequent expansion of the West African forest . West African hunter-gatherers occupied western Central Africa (e.g., Shum Laka ) earlier than 32,000 BP, dwelled throughout coastal West Africa by 12,000 BP, and migrated northward between 12,000 BP and 8000 BP as far as Mali, Burkina Faso, and Mauritania. During the Holocene , Niger-Congo speakers independently created pottery in Ounjougou , Mali –

7896-611: The traditional name for the area near the Gulf of Guinea ; Mauritania lies in the Maghreb , the northwestern region of Africa that has historically been inhabited by West African groups such as the Fulani , Soninke , Wolof , Serer and Toucouleur people , along with Arab-Berber Maghrebi people such as the Tuareg ; Cape Verde is an island country in the Atlantic Ocean ; and Saint Helena, Ascension and Tristan da Cunha consists of eight main islands located in four different parts of

7990-470: The western Maghreb) is composed of semi-arid terrain known as Sahel , a transitional zone between the Sahara and the West Sudanian savanna . Forests form a belt between the savannas and the southern coast, ranging from 160 km to 240 km in width. The northwest African region of Mauritania periodically suffers country-wide plagues of locusts which consume water, salt and crops on which

8084-545: The western Sahel, and increases more likely in the central to east Sahel, although opposite trends cannot yet be ruled out. These trends will affect the frequency and severity of floods, droughts, desertification , sand and dust storms, desert locust plagues and water shortages. However, irrespective of the changes in seasonal mean rain, the most intense storms are expected to become more intense, amplifying flood frequency. Enhanced carbon emissions and global warming may also lead to an increase in dry spells especially across

8178-517: Was a Yoruba empire of what is today Western, North Central Nigeria and Southern Republic of Benin . Established in the 14th century, the Oyo Empire grew to become one of the largest West African states. It rose through the outstanding organizational skills of the Yoruba, wealth gained from trade and its powerful cavalry . The Oyo Empire was the most politically important state in the region from

8272-463: Was a mystery to the outside world until the late 18th century. The connection to the Nile River was made not simply because this was then known as the great river of " Aethiopia " (by which all lands south of the desert were called by Classical writers), but because the Nile like the Niger flooded every summer. Through the descriptions of Leo Africanus and even Ibn Battuta – despite his visit to

8366-415: Was arrested and charged with complicity in the kidnapping and disappearance of rivals within the Malian military. He remains in detention while awaiting trial. In January 2020, it was announced that Sanogo would be released pending his upcoming trial. This was in accordance with a court decision ordering Sanogo's release after Sanogo's trial date was postponed at the last minute. Niger River This

8460-469: Was estimated at 25 km /year before the 1980s and at 13.5 km /year during the 1980s. The most important tributary is the Benue River which merges with the Niger at Lokoja in Nigeria. The total volume of tributaries in Nigeria is six times higher than the inflow into Nigeria, with a flow near the mouth of the river standing at 177.0 km /year before the 1980s and 147.3 km /year during

8554-499: Was left of the local wildlife, but by that time, it was too late. During the 1930s, the elephant population in the Gold Coast was about 300, and Sierra Leone between 500 and 600. Although a small number of elephants survived in Nigeria, hunting, agricultural expansion and clearing of forest in that country drastically affected its wildlife population, particularly elephants. Despite the historical damage that has been done to

8648-511: Was the same as the actual Niger, or rather the river also known as Ger (currently known as Oued Guir, in Morocco), is a matter of discussion. This Nigris was said to divide "Africa proper" from the land of the (Western) Ethiopians to the south, and its name (as well as that of the river Ger) might well come from the Berber phrase gr-n-grwn meaning "river of rivers", as the current Tuareg name for

8742-625: Was then succeeded by the Ghana Empire that first flourished roughly between the 2nd and 12th centuries C.E., which later gave way to the Mali Empire . In current-day Mauritania, there exist archaeological sites in the towns of Tichit and Oualata that were initially constructed around 2000 B.C., and were found to have originated from the Soninke branch of the Mandé peoples . Also, based on

8836-743: Was used to illustrate Rouch's subsequent book "Le Niger En Pirogue" (Fernand Nathan, 1954), as well as Sauvy's "Descente du Niger" (L'Harmattan, 2001). A typewriter was brought as well, on which Ponty produced newspaper articles he mailed out whenever possible. The water in the Niger River basin is partially regulated through dams. In Mali the Sélingué Dam on the Sankarani River is mainly used for hydropower but also permits irrigation. Two diversion dams, one at Sotuba just downstream of Bamako , and one at Markala , just downstream of Ségou , are used to irrigate about 54,000 hectares. In Nigeria
