45-413: Tambacounda is situated on the sparsely populated sahélien plains of eastern Senegal. Nearby towns include Madina Maboule, Koukari, Yoro Sankoule, Sambadian, Djidje Kounda, Afia Seno, Saare Boylii and Kanderi Niana. Tambacounda has a hot semi-arid climate ( BSh ). Like most of West Africa , the area has two seasons, the rainy season from June to October, characterized by heat, humidity and storms, and

90-575: A great deal of autonomy. The larger Sahelian kingdoms emerged from 750 AD and erected several large cities in the Niger valley region, including Timbuktu , Gao and Djenné . Due to the wooded areas to their south, the Sahelian states were hindered from expanding into the north Akan state of the Bonoman and Yoruba peoples , as mounted warriors were all but useless in the forests. In addition,

135-448: A relative humidity under 35%. The Sahel is characterized by constant, intense heat, with an unvarying temperature. The Sahel rarely experiences cold temperatures. During the hottest period, the average high temperatures are generally between 36 and 42 °C (97 and 108 °F) (and even more in the hottest regions), often for more than three months, while the average low temperatures are around 25 to 31 °C (77 to 88 °F). During

180-623: A series of monarchies centered in the Sahel between the 9th and 18th centuries. The wealth of the states, like the legendary Mali Empire at the time of Mansa Musa , came from controlling the trans-Saharan trade routes across the desert, especially with the Maghreb . Their power came from having large pack animals like camels and horses that were fast enough to keep a large empire under central control and were also useful in battle. All of these empires were quite decentralized with member cities having

225-560: A system of transhumance . The difference between the dry North with higher levels of soil nutrients and the wetter South with more vegetation, is utilized by having the herds graze on high-quality feed in the North during the wet season, and trek several hundred kilometers to the South to graze on more abundant, but less nutritious feed during the dry period. In Western Sahel, polygamy and child marriage are common. Female genital mutilation

270-794: A warmer Atlantic Ocean. Warming of the Mediterranean Sea may also be a factor. Protected areas in the Sahel include Ferlo Nord Wildlife Reserve in Senegal, Sylvo-Pastoral and Partial Faunal Reserve of the Sahel in Burkina Faso, Ansonga-Ménake Faunal Reserve in Mali, Tadres Reserve in Niger, and Waza National Park in Cameroon. Traditionally, most of the people in the Sahel have been semi- nomads , farming and raising livestock in

315-608: Is a common area for dust storms, occurring on average on 100 days every year. On 23 March 2010, a major sandstorm hit Mauritania, Senegal, The Gambia , Guinea-Bissau , Guinea , and inland Sierra Leone . Another struck in southern Algeria , inland Mauritania, Mali and northern Ivory Coast at the same time. Following the drought period of the 1970s and 1980, however, the Sahel began to experience increased rainfall. This may be due to global warming , which can cause changes that may result in changes in large-scale weather patterns, such as increased stronger monsoons, in turn caused by

360-400: Is also a center for agricultural processing, with millet, sorgum, maize and cotton grown in the dry plains of the region. Sodefitex operates a large cotton processing plant in the town. Tambacounda is the capital of Tambacounda Department (which includes three administrative regions) and the large Tambacounda Region . The Niokolo-Koba National Park lies just to the south of the town, and

405-541: Is also called the Sahelian Acacia savanna in honour of its most prominent and very drought tolerant genus of tree. The topography of the Sahel is mainly flat; most of the region lies between 200 and 400 meters (660 and 1,310 ft) in elevation. Several isolated plateaus and mountain ranges rise from the Sahel (e.g. Marrah Mountains , Aïr Mountains , Ennedi Plateau ), but are designated as separate ecoregions because their flora and fauna are distinct from

450-525: Is also practiced across the Sahel. The term "Sahel" is borrowed from the Arabic name for the region, الساحل al-sāḥil . Sāḥil literally means "coast, shore", which has been explained as a figurative reference to the southern edge of the vast Sahara. However, such use is unattested in Classical Arabic , and it has been suggested that the word may originally have been derived from

495-525: Is famed for its wildlife. In 2003, the iron-framed rail station, the Hôtel de la Gare, and the colonial Préfecture building were placed on Senegal's list of Monuments historiques . Sahel The Sahel region ( / s ə ˈ h ɛ l / ; from Arabic ساحل ( sāḥil [ˈsaːħil] )  'coast, shore'), or Sahelian acacia savanna , is a biogeographical region in Africa . It

540-413: Is only a matter of time before countries like Niger lose their entire landmass to desert due to unchecked unsustainable human practices. Over-farming , over-grazing, over-population of marginal lands, and natural soil erosion , have caused serious desertification of the region. This has affected shelter construction, making it necessary to change the used materials. The Woodless Construction project

585-590: Is probably extinct in the wild , and both Pelorovis and the Bubal hartebeest are now extinct). The seasonal wetlands of the Sahel are important for migratory birds moving within Africa and on the African-Eurasian flyways . The Sahel has a tropical semi-arid climate ( Köppen climate classification BSh ). The climate is typically hot, sunny, dry and somewhat windy all year long. The Sahel's climate

630-461: Is similar to, but less extreme than, the climate of the Sahara desert located just to the north. The Sahel mainly receives a low to very low amount of precipitation annually. The steppe has a very long, prevailing dry season and a short rainy season. The precipitation is also extremely irregular, and varies considerably from season to season. Most of the rain usually falls during four to six months in

675-617: Is the transition zone between the more humid Sudanian savannas to its south and the drier Sahara to the north. The Sahel has a hot semi-arid climate and stretches across the southernmost latitudes of North Africa between the Atlantic Ocean and the Red Sea . Although geographically located in the tropics, the Sahel does not have a tropical climate . Especially in the western Sahel, there are frequent shortages of food and water due to its very high government corruption and

720-624: The G5 Sahel , an anti-terrorism alliance, after the military regimes in Burkina Faso, Niger, and Mali withdrew. On 9 July 2020, the United States raised concerns over growing number of allegations of human rights violations and abuses by state security forces in Sahel. The US response came after Human Rights Watch released documents regarding the same on 1 July. Reports in March 2022 show militants are expanding and spreading out south of

765-417: The Red Sea in the east, in a belt several hundred to a thousand kilometers (c. 600 miles) wide. It covers an area of 3,053,200 square kilometers (1,178,850 sq mi). Representing a climatic and ecological transition zone with hot semi-desert and steppe conditions , the Sahel region borders the more humid Sudanian savannas to its south and the dry Sahara desert to the north. This ecoregion

810-400: The semi-arid climate . This is exacerbated by very high birthrates across the region, resulting in a rapid increase in population. In recent times, various coups , insurgencies , terrorism and foreign interventions have taken place in many Sahel countries, especially across former Françafrique . The Sahel spans 5,900 km (3,670 mi) from the Atlantic Ocean in the west to

855-429: The "coldest period", the average high temperatures are between 27 and 33 °C (81 and 91 °F) and the average low temperatures are between 15 and 21 °C (59 and 70 °F). Everywhere in the Sahel, the average mean temperature is over 18 °C (64 °F). The Sahel has a high to very high sunshine duration year-round, between 2,400 hours (about 55% of the daylight hours) and 3,600 hours (more than 80% of

900-566: The Arabic word سهل sahl "plain" instead. Around 4000 BC, the climate of the Sahara and the Sahel started to become drier at an exceedingly fast pace. This climate change caused lakes and rivers to shrink significantly and caused increasing desertification . This, in turn, decreased the amount of land conducive to settlements and caused migrations of farming communities to the more humid climate of West Africa . The Sahelian kingdoms were

945-410: The Sahel region has experienced frequent droughts and megadroughts . One megadrought lasted from 1450 to 1700, 250 years. There was a major drought in the Sahel in 1914 caused by annual rains far below average, leading to large-scale famine. From 1951 to 2004, the Sahel experienced some of the most consistent and severe droughts in Africa. The 1960s saw a large increase in rainfall in the region, making

990-473: The Sahel. The area has also seen a high prevalence of coups d'état , with military juntas currently ruling in Mali, Burkina Faso, Niger, Chad, and Sudan. The violent herder–farmer conflicts in Nigeria , Mali , Sudan and other countries in the Sahel region have been exacerbated by climate change , land degradation , and rapid population growth . Droughts and food shortages have been also linked to

1035-648: The beginning of the 20th century. There is a Roman Catholic Diocese of Tambacounda , but only 1.8% of the population of the region is Roman Catholic . Besides the Dakar–Bamako railway , historically the city's major engine of growth, Tambacounda lies on the N1 and N7 roads . As a part of the Trans-Sahelian Highway system, these are critical for traffic going between the Kayes Region of Mali and

1080-623: The coastal regions of Sénégal ( Dakar , Thiès , Saint-Louis ), the most densely populated parts of both these nations. This east–west travel intersects with Senegal's most important route from Dakar to the Casamance region, which is cut off by Gambia . The road through Tambacounda is the only internal route between the two parts of the country that does not cross the Gambian border. The town also has an airport, Tambacounda Airport , serviced by national and international flights. Tambacounda

1125-501: The community after him. The town, a center of the peanut trade with the English, was attacked by Bundu in 1863. The Kingdom of Wuli became a French protectorate in 1888. The Dakar–Bamako railway reached Tambacounda in 1913. In 1919, it became the administrative capital of a new eponymous cercle . With access to the railroad, in the 1920s came more intensive cultivation of grains, peanuts and cotton. French colonial authorities made

1170-534: The daylight hours). The sunshine duration in the Sahel approaches desert levels, and is comparable to that in the Arabian Desert , for example, even though the Sahel is only a steppe and not a desert. The cloud cover is low to very low. For example, Niamey , Niger has 3,082 hours of bright sunshine; Gao , Mali has near 3,385 hours of sunshine; Timbuktu , Mali has 3,409 sunny hours, and N'Djamena , Chad has 3,205 hours of sunlight. For hundreds of years,

In

1260-671: The founding of the International Fund for Agricultural Development . Between June and August 2010, famine struck the Sahel. Niger's crops failed to mature in the heat, 350,000 faced starvation, and 1,200,000 were at risk of famine. In Chad the temperature reached 47.6 °C (117.7 °F) on 22 June in Faya-Largeau , breaking a record set in 1961 at the same location. Niger tied its highest temperature record set in 1998, also on 22 June, at 47.1 °C in Bilma . That record

1305-888: The giant prehistoric buffalo ( Pelorovis ) , and Bubal hartebeest (Alcelaphus buselaphus buselaphus) , along with large predators, such as the African wild dog (Lycaon pictus) , the Northwest African cheetah (Acinonyx jubatus hecki) , the Northeast African cheetah (Acinonyx jubatus soemmeringii) , and the lion (Panthera leo) . The larger species have been greatly reduced in number by over-hunting and competition with livestock, and several species are vulnerable (Dorcas gazelle, cheetah, lion and red-fronted gazelle), endangered ( Dama gazelle and African wild dog ), or extinct (the Scimitar-horned oryx

1350-399: The heat reached near-record levels over Chad and Niger, and in northern Niger about 20 people reportedly died of dehydration by 27 July. The Sahel region faces environmental issues that are contributing to global warming . If the change in climate in the Sahel region "is not slowed-down and desertification possibly reversed through sustainable practices and any form of reforestation , it

1395-530: The horses and camels were susceptible to the humidity and diseases of the tropics. The Western Sahel fell to France in the late 19th century as part of French West Africa . Chad was added in 1900 as part of French Equatorial Africa . The French territories in the Sahel were decolonized in 1960. The Sahel's easternmost region did not fall to the European powers but to the Khedivate of Egypt when it

1485-473: The middle of the year, while the other months may remain absolutely dry. The interior of the Sahel region generally receives between 200 mm and 700 mm of rain yearly. A system of subdivisions often adopted for the Sahelian climate based on annual rainfall is as follows: the Saharan-Sahelian climate, with mean annual precipitation between around 100 and 200 mm (such as Khartoum , Sudan),

1530-433: The northern drier region more accessible. There was a push, supported by governments, for people to move northwards. When the long drought period from 1968 through 1974 began, grazing quickly became unsustainable and large-scale denuding of the terrain followed. Like the drought in 1914, this led to a large-scale famine, but this time somewhat tempered by international visibility and an outpouring of aid. This catastrophe led to

1575-500: The northern part of the Sahel, areas of desert shrub, including Panicum turgidum and Aristida sieberiana , alternate with areas of grassland and savanna. During the long dry season, many trees lose their leaves and the predominantly annual grasses die. The Sahel was formerly home to large populations of grazing mammals, including the scimitar-horned oryx (Oryx dammah) , dama gazelle (Gazella dama) , Dorcas gazelle (Gazella dorcas) , red-fronted gazelle (Gazella rufifrons) ,

1620-442: The population reached 78,800 persons. Settled first by Mandinka people , on the regular transhumance routes of Fula cattle herders , and settled again by Wolof farmers in the early 20th century, Tambacounda has a mix of most of the ethnic groups in Senegal . The Tambacounda region is famous for its rich djembe and dance culture and heritage with some of the greatest djembe masters from Segu, Mali coming to Tambacounda in

1665-511: The strict Sahelian climate, with mean annual precipitation between around 200 and 700 mm (such as Niamey , Niger) and the Sahelian-Sudanese climate, with mean annual precipitation between around 700 and 900 mm (such as Ouagadougou , Burkina Faso). The relative humidity in the steppe is low to very low, often between 10% and 25% during the dry season and between 25% and 75% during the rainy season. The least humid places have

1710-495: The surrounding lowlands (e.g. East Saharan woodlands ). Annual rainfall varies from around 100–200 mm (4–8 in) in the north of the Sahel to around 700–1,000 mm (28–39 in) in the south. The Sahel is mostly covered in grassland and savanna, with areas of woodland and shrubland. Grass cover is fairly continuous across the region, dominated by annual grass species such as Cenchrus biflorus , Schoenefeldia gracilis and Aristida stipoides . Species of acacia are

1755-541: The sweltering, rainless dry season from November to May. The average precipitation is 742 mm (29.2 in). Tambacounda was founded by Mandinka settlers of the Jatta (Diatta) family who had been driven out of the valley of the Faleme river by an expanding Bundu in the 18th century. When they arrived at the future side of Tambacounda they found a single hut, inhabited by a slave named Tamba, who welcomed them, and named

1800-501: The town a major transport hub , and a number of buildings, including the rail station retain the colonial flavor. The train ran until 2018, when it was forced out of service due to a lack of maintenance of the rails. As of January 2024, however, major upgrades are being done, with plans to relaunch passenger and freight service between Tambacounda and Dakar . Between the censuses of 1988 and 2002, Tambacounda grew from 41,885 to 67,543 inhabitants. In 2007, according to official estimates,

1845-709: The violence, extremism and instability of the region. In March 2020, the United States sent a special envoy for the Sahel region to combat the rising violence from terrorist groups. The Catholic charity Aid to the Church in Need has highlighted the fact that the Sahel has become one of the most dangerous regions in the world for Christians. As of 2024, a wave of new military juntas in Africa, favoring Russian mercenaries over Western forces and UN peacekeepers, has intensified violence. This led Mauritania and Chad to disband

The hottest temperature recorded in Sudan was reached on 25 June, at 49.6 °C (121.3 °F) in Dongola , breaking a record set in 1987. Niger reported on 14 July that diarrhoea , starvation, gastroenteritis , malnutrition and respiratory diseases had sickened or killed many children. The new military junta appealed for international food aid and took serious steps to call on overseas help. On 26 July,

2025-624: Was introduced in Sahel in 1980 by the Development Workshop, achieving since then a high social impact in the region. A major initiative to combat desertification in the Sahel region via reforestation and other interventions is the Great Green Wall . Major dust storms are a frequent occurrence as well. During November 2004, a number of major dust storms hit Chad , originating in the Bodélé Depression . This
