Though possibly developed as early as 5000 BCE, Nsibidi may have also developed in 2000 BCE, as evidenced by depictions of the West African script on Ikom monoliths at Ikom , in Nigeria . Migration of Saharan peoples south of

294-829: A 3.2% rise in global deforestation. Massive wildfires in Canada , exacerbated by climate change , contributed to a 24% increase in global tree cover loss, highlighting the ongoing threats to forests essential for carbon storage and biodiversity . Despite some progress, the overall trends in forest destruction and climate impacts remain off track. The IPCC Sixth Assessment Report stated in 2022: “Over 420 million ha of forest were lost to deforestation from 1990 to 2020; more than 90% of that loss took place in tropical areas (high confidence), threatening biodiversity, environmental services, livelihoods of forest communities and resilience to climate shocks (high confidence).” See also: Global deforestation sharply accelerated around 1852. As of 1947,

In Cape Verde, the fishermen communities of Palmiera and Santa Maria have organized themselves to protect fishing zones. Mozambique finally created a conservation area, including a coastline. West Africa, broadly defined to include the western portion of the Maghreb ( Western Sahara , Morocco , Algeria , and Tunisia ), occupies an area in excess of 6,140,000 km , or approximately one-fifth of Africa. The vast majority of this land

588-590: A result of increasing aridification of the Green Sahara , Central Saharan hunter-gatherers and cattle herders may have used seasonal waterways as the migratory route taken to the Niger River and Chad Basin of West Africa. In 2000 BCE, " Thiaroye Woman", also known as the " Venus of Thiaroye", may have been the earliest statuette created in Sub-Saharan West Africa; it may have particularly been

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

784-547: 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

The eastern end of the highway terminates at Lagos , Nigeria . Economic Community of West African States (ECOWAS) consider its western end to be Nouakchott , Mauritania , or to be Dakar , Senegal , giving rise to these alternative names for

980-407: Is agreement that destruction of rainforests remains a significant environmental problem. The rate of net forest loss declined from 7.8 million ha per year in the decade 1990–2000 to 5.2 million ha per year in 2000–2010 and 4.7 million ha per year in 2010–2020. The rate of decline of net forest loss slowed in the most recent decade due to a reduction in the rate of forest expansion. In many parts of

1078-754: Is around 38%. Since 1960, roughly 15% of the Amazon has been removed with the intention of replacing the land with agricultural practices. It is no coincidence that Brazil has recently become the world's largest beef exporter at the same time that the Amazon rainforest is being clear cut. Another prevalent method of agricultural deforestation is slash-and-burn agriculture , which was primarily used by subsistence farmers in tropical regions but has now become increasingly less sustainable. The method does not leave land for continuous agricultural production but instead cuts and burns small plots of forest land which are then converted into agricultural zones. The farmers then exploit

1176-399: Is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh , are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in

1274-421: Is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or negative, depending on whether gains exceed losses, or vice versa. The FAO estimates that

1372-549: Is demographically and economically one of the fastest growing on the African continent. Early history in West Africa includes a number of prominent regional powers that dominated different parts of both the coastal and internal trade networks, such as the Mali and Gao Empires . West Africa sat at the intersection of trade routes between Arab -dominated North Africa and further south on

1470-605: Is estimated that some 420 million hectares of forest have been lost through conversion to other land uses , although the rate of deforestation has decreased over the past three decades. Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down from 16 million hectares per year in the 1990s. The area of primary forest worldwide has decreased by over 80 million hectares since 1990. More than 100 million hectares of forests are adversely affected by forest fires, pests, diseases, invasive species , drought and adverse weather events. Deforestation

1568-601: Is not an issue because of longer fallow periods and lesser overall deforestation. The relatively small size of the plots allowed for no net input of CO 2 to be released. Consumption and production of beef is the primary driver of deforestation in the Amazon , with around 80% of all converted land being used to rear cattle. 91% of Amazon land deforested since 1970 has been converted to cattle ranching. Livestock ranching requires large portions of land to raise herds of animals and livestock crops for consumer needs. According to

Benin Burkina Faso The Gambia Ghana Guinea-Bissau Guinea Ivory Coast Liberia Mali Mauritania Nigeria Niger Senegal Sierra Leone Togo The northern section of West Africa (narrowly defined to exclude

1764-453: Is projected to occur by the mid-21st century. In the early 2000s, some scientists predicted that unless significant measures (such as seeking out and protecting old growth forests that have not been disturbed) are taken on a worldwide basis, by 2030 there will only be 10% remaining, with another 10% in a degraded condition . 80% will have been lost, and with them hundreds of thousands of irreplaceable species. Estimates vary widely as to

Ngoye njuli is protected by the Senegalese authorities and attracts visitors. 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

1960-727: Is responsible for 48% of deforestation; commercial agriculture is responsible for 32%; logging is responsible for 14%, and fuel wood removals make up 5%. More than 80% of deforestation was attributed to agriculture in 2018. Forests are being converted to plantations for coffee, tea, palm oil , rice, rubber , and various other popular products. The rising demand for certain products and global trade arrangements causes forest conversions , which ultimately leads to soil erosion . The top soil oftentimes erodes after forests are cleared which leads to sediment increase in rivers and streams. Most deforestation also occurs in tropical regions. The estimated amount of total land mass used by agriculture

2058-461: Is that deforestation reduces the uptake of carbon dioxide ( carbon sequestration ) from the atmosphere. This reduces the potential of forests to assist with climate change mitigation . The role of forests in capturing and storing carbon and mitigating climate change is also important for the agricultural sector. The reason for this linkage is because the effects of climate change on agriculture pose new risks to global food systems . Since 1990, it

West Africa West Africa , also called Western Africa , is the westernmost region of Africa . The United Nations defines Western Africa as

2254-622: 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

2352-554: 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

2450-545: The Congolese rainforest increased by 5%. The World Wildlife Fund 's ecoregion project catalogues habitat types throughout the world, including habitat loss such as deforestation, showing for example that even in the rich forests of parts of Canada such as the Mid-Continental Canadian forests of the prairie provinces half of the forest cover has been lost or altered. In 2011, Conservation International listed

2548-708: 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

2646-697: The Philippines , Indonesia , Thailand , Burma , Malaysia , Bangladesh , China, Sri Lanka , Laos , Nigeria , the Democratic Republic of the Congo , Liberia , Guinea , Ghana and the Ivory Coast , have lost large areas of their rainforest. Much of what remains of the world's rainforests is in the Amazon basin , where the Amazon Rainforest covers approximately 4 million square kilometres. Some 80% of

2744-726: 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

The cattle industry is responsible for a significant amount of methane emissions since 60% of all mammals on earth are livestock cows. Replacing forest land with pastures creates a loss of forest stock , which leads to

3136-577: The tropics . In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests . These are areas of mature rainforest that are especially important for biodiversity and carbon storage . The direct cause of most deforestation is agriculture by far. More than 80% of deforestation was attributed to agriculture in 2018. Forests are being converted to plantations for coffee , palm oil , rubber and various other popular products. Livestock grazing also drives deforestation. Further drivers are

3234-574: The wood industry ( logging ), urbanization and mining . The effects of climate change are another cause via the increased risk of wildfires (see deforestation and climate change ). Deforestation results in habitat destruction which in turn leads to biodiversity loss . Deforestation also leads to extinction of animals and plants, changes to the local climate, and displacement of indigenous people who live in forests. Deforested regions often also suffer from other environmental problems such as desertification and soil erosion . Another problem

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

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

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

4312-562: 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

4410-508: 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

Only Liberia retained its independence, at the price of major territorial concessions. Following World War II , nationalist movements arose across West Africa. In 1957, Ghana, under Kwame Nkrumah , became the first West African colony to achieve its independence, followed

4704-626: The commodity is consumed. For example, consumption patterns in G7 countries are estimated to cause an average loss of 3.9 trees per person per year. In other words, deforestation can be directly related to imports—for example, coffee. In 2023, the Global Forest Watch reported a 9% decline in tropical primary forest loss compared to the previous year, with significant regional reductions in Brazil and Colombia overshadowed by increases elsewhere, leading to

In 2009, Paraguay's parliament refused to pass a law that would have stopped cutting of natural forests altogether. As of 2007, less than 50% of Haiti's forests remained . From 2015 to 2019, the rate of deforestation in the Democratic Republic of the Congo doubled. In 2021, deforestation of

4998-774: The decades 1990–2000 and 2000–2010. Some claim that rainforests are being destroyed at an ever-quickening pace. The London-based Rainforest Foundation notes that "the UN figure is based on a definition of forest as being an area with as little as 10% actual tree cover, which would therefore include areas that are actually savanna-like ecosystems and badly damaged forests". Other critics of the FAO data point out that they do not distinguish between forest types, and that they are based largely on reporting from forestry departments of individual countries, which do not take into account unofficial activities like illegal logging. Despite these uncertainties, there

5096-498: The deforestation of the Amazon can be attributed to cattle ranching, as Brazil is the largest exporter of beef in the world. The Amazon region has become one of the largest cattle ranching territories in the world. The regions with the highest tropical deforestation rate between 2000 and 2005 were Central America —which lost 1.3% of its forests each year—and tropical Asia. In Central America , two-thirds of lowland tropical forests have been turned into pasture since 1950 and 40% of all

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

5390-463: The extent of deforestation in the tropics. In 2019, the world lost nearly 12 million hectares of tree cover. Nearly a third of that loss, 3.8 million hectares, occurred within humid tropical primary forests, areas of mature rainforest that are especially important for biodiversity and carbon storage. This is equivalent to losing an area of primary forest the size of a football pitch every six seconds. A 2002 analysis of satellite imagery suggested that

The vast majority of agricultural activity resulting in deforestation is subsidized by government tax revenue . Disregard of ascribed value, lax forest management , and deficient environmental laws are some of the factors that lead to large-scale deforestation. The types of drivers vary greatly depending on

5586-579: The fruit and seeds are used for drinks and oils. West Africa is greatly affected by deforestation and has one of the worst deforestation rate. Even "the beloved baobab tree" which is viewed as sacred by some West African cultures are under threat due to climate change , urbanization and population growth. "Huge swaths of forest are being razed to clear space for palm oil and cocoa plantations. Mangroves are being killed off by pollution. Even wispy acacias are hacked away for use in cooking fires to feed growing families." Nigeria, Liberia, Guinea, Ghana and

As of 2019 there is still disagreement about whether the global forest is shrinking or not: "While above-ground biomass carbon stocks are estimated to be declining in the tropics, they are increasing globally due to increasing stocks in temperate and boreal forest. Deforestation in many countries —both naturally occurring and human-induced —is an ongoing issue. Between 2000 and 2012, 2.3 million square kilometres (890,000 square miles) of forests around

The rate of net forest loss has increased in Africa in each of the three decades since 1990. It has declined substantially in South America, however, to about half the rate in 2010–2020 compared with 2000–2010. Asia had the highest net gain of forest area in 2010–2020, followed by Oceania and Europe. Nevertheless, both Europe and Asia recorded substantially lower rates of net gain in 2010–2020 than in 2000–2010. Oceania experienced net losses of forest area in

As well as, intentionally set fires can possibly lead to devastating measures when unintentionally spreading fire to more land, which can result in the destruction of the protective canopy. The repeated cycle of low yields and shortened fallow periods eventually results in less vegetation being able to grow on once burned lands and a decrease in average soil biomass. In small local plots sustainability

6958-449: The opposite trends illustrated opposite tendencies (e.g. central and northern Senegal). Those patterns were further even more stimulated by the French colonial campaign. Britain controlled the Gambia, Sierra Leone, Ghana, and Nigeria throughout the colonial era, while France unified Senegal, Guinea, Mali, Burkina Faso, Benin, Ivory Coast, and Niger into French West Africa . Portugal founded

7056-548: The original 16 million square kilometres (6 million square miles) of tropical rainforest that formerly covered the Earth. More than 3.6 million hectares of virgin tropical forest was lost in 2018. The global annual net loss of trees is estimated to be approximately 10 billion. According to the Global Forest Resources Assessment 2020 the global average annual deforested land in the 2015–2020 demi-decade

7154-418: The other hand, a 2005 analysis of satellite images reveals that deforestation of the Amazon rainforest is twice as fast as scientists previously estimated. From 2010 to 2015, worldwide forest area decreased by 3.3 million ha per year, according to FAO . During this five-year period, the biggest forest area loss occurred in the tropics, particularly in South America and Africa. Per capita forest area decline

7252-410: The planet had 15 to 16 million km (5.8 to 6.2 million sq mi) of mature tropical forests , but by 2015, it was estimated that about half of these had been destroyed. Total land coverage by tropical rainforests decreased from 14% to 6%. Much of this loss happened between 1960 and 1990, when 20% of all tropical rainforests were destroyed. At this rate, extinction of such forests

7350-400: The population has been affected by five or more floods in the 17 Sahel region countries. In 2012, severe drought conditions in the Sahel were reported. Governments in the region responded quickly, launching strategies to address the issue. The region is projected to experience changes in rainfall regime, with climate models suggesting that decreases in wet season rainfall are more likely in

7448-469: The pressure for economic development, many of these ecologies are threatened by processes like deforestation , biodiversity loss , overfishing , pollution from mining , plastics and other industries, and extreme changes resulting from climate change in West Africa . The history of West Africa can be divided into five major periods: first, its prehistory, in which the first human settlers arrived, developed agriculture , and made contact with peoples to

7546-488: The rainforests have been lost in the last 40 years. Brazil has lost 90–95% of its Mata Atlântica forest. Deforestation in Brazil increased by 88% for the month of June 2019, as compared with the previous year. However, Brazil still destroyed 1.3 million hectares in 2019. Brazil is one of several countries that have declared their deforestation a national emergency. Paraguay was losing its natural semi-humid forests in

7644-463: The rate of deforestation in the humid tropics (approximately 5.8 million hectares per year) was roughly 23% lower than the most commonly quoted rates. A 2005 report by the United Nations Food and Agriculture Organization (FAO) estimated that although the Earth's total forest area continued to decrease at about 13 million hectares per year, the global rate of deforestation had been slowing. On

7742-469: The region in which they take place. The regions with the greatest amount of deforestation for livestock and row crop agriculture are Central and South America, while commodity crop deforestation was found mainly in Southeast Asia. The region with the greatest forest loss due to shifting agriculture was sub-Saharan Africa. The overwhelming direct cause of deforestation is agriculture. Subsistence farming

7840-447: 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

7938-512: 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

8036-453: 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

8134-547: The road: The capitals' airports include: Of the sixteen, the most important hub and entry point to West Africa are Kotoka International Airport , and Murtala Muhammed International Airport , offering many international connections. Deforestation Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms , ranches , or urban use. About 31% of Earth's land surface

8232-651: 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

8330-513: The size of India—by 2050. 36% of globally planted forest area is in East Asia – around 950,000 square kilometers. From those 87% are in China. Rates of deforestation vary around the world. Up to 90% of West Africa 's coastal rainforests have disappeared since 1900. Madagascar has lost 90% of its eastern rainforests. In South Asia , about 88% of the rainforests have been lost. Mexico , India ,

8428-728: 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 ,

8526-528: 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 –

8624-467: The top 10 most endangered forests, characterized by having all lost 90% or more of their original habitat , and each harboring at least 1500 endemic plant species (species found nowhere else in the world). As of 2015 , it is estimated that 70% of the world's forests are within one kilometer of a forest edge, where they are most prone to human interference and destruction. Deforestation in particular countries: Agricultural expansion continues to be

8722-649: 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

8820-463: 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

8918-545: 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

9016-473: The world were cut down. Deforestation and forest degradation continue to take place at alarming rates, which contributes significantly to the ongoing loss of biodiversity . Deforestation is more extreme in tropical and subtropical forests in emerging economies. More than half of all plant and land animal species in the world live in tropical forests . As a result of deforestation, only 6.2 million square kilometres (2.4 million square miles) remain of

9114-564: The world, especially in East Asian countries, reforestation and afforestation are increasing the area of forested lands. The amount of forest has increased in 22 of the world's 50 most forested nations. Asia as a whole gained 1 million hectares of forest between 2000 and 2005. Tropical forest in El Salvador expanded more than 20% between 1992 and 2001. Based on these trends, one study projects that global forestation will increase by 10%—an area

9212-456: Was 10 million hectares and the average annual forest area net loss in the 2000–2010 decade was 4.7 million hectares. The world has lost 178 million ha of forest since 1990, which is an area about the size of Libya. An analysis of global deforestation patterns in 2021 showed that patterns of trade, production, and consumption drive deforestation rates in complex ways. While the location of deforestation can be mapped, it does not always match where

9310-507: 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

9408-461: Was also greatest in the tropics and subtropics but is occurring in every climatic domain (except in the temperate) as populations increase. An estimated 420 million ha of forest has been lost worldwide through deforestation since 1990, but the rate of forest loss has declined substantially. In the most recent five-year period (2015–2020), the annual rate of deforestation was estimated at 10 million ha, down from 12 million ha in 2010–2015. Africa had

9506-493: 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

9604-604: 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
