West Sudanian savanna in the context of "Kwara State"

The Mandinka or Malinke are a West African ethnic group primarily found in southern Mali, The Gambia, southern Senegal and eastern Guinea. Numbering about 15 million, they are the largest subgroup of the Mandé peoples and one of the largest ethnolinguistic groups in Africa. They speak the Manding languages in the Mande language family, which are a lingua franca in much of West Africa. They are predominantly subsistence farmers and live in rural villages. Their largest urban center is Bamako, the capital of Mali.

The Mandinka are the descendants of the Mali Empire, which rose to power in the 13th century under the rule of king Sundiata Keita, who founded an empire that would go on to span a large part of West Africa. They migrated west from the Niger River in search of better agricultural lands and more opportunities for conquest. Nowadays, the Mandinka inhabit the West Sudanian savanna region extending from The Gambia and the Casamance region in Senegal, Mali, Guinea and Guinea Bissau. Although widespread, the Mandinka constitute the largest ethnic group only in the countries of Mali, Guinea and The Gambia. Most Mandinka live in family-related compounds in traditional rural villages. Their traditional society has featured socially stratified castes. Mandinka communities have been fairly autonomous and self-ruled, being led by a chief and group of elders. Mandinka has been an oral society, where mythologies, history and knowledge are verbally transmitted from one generation to the next. Their music and literary traditions are preserved by a caste of griots, known locally as jalolu (singular, jali), as well as guilds and brotherhoods like the donso (hunters).

Adamawa is a state in the North-East geopolitical zone of Nigeria, bordered by Borno to the northwest, Gombe to the west, and Taraba to the southwest while its eastern border forms part of the national border with Cameroon. It takes its name from the historic emirate of Adamawa, with the emirate's old capital of Yola serving as the capital city of Adamawa State. The state was formed in 1991 when the former Gongola State was broken up into Adamawa and Taraba states. The state is one of the most heterogeneous in Nigeria, having over 100 indigenous ethnic groups.

Of the 36 states, Adamawa is the eighth largest in the area, but the thirteenth least populous with an estimated population of about 4.25 million as of 2016. Geographically, the state is mainly composed of highlands and mountains (the Atlantika, Mandara, and the Shebshi ranges) and the Adamawa Plateau crossed by valleys and rivers, most notably the Benue and Gongola rivers. The lowlands of Adamawa are all part of the West Sudanian savanna in the north and the wetter Guinean forest-savanna mosaic in parts of the south, while elevated areas are parts of the Mandara Plateau mosaic and Cameroonian Highlands forests ecoregions. In the extreme south of the state is part of the Gashaka Gumti National Park, a large wildlife park that contains large populations of bushbuck, African buffalo, patas monkey, black-and-white colobus, giant pangolin, and hippopotamus along with some of Nigeria's last remaining Nigeria-Cameroon chimpanzee, African leopard, and African golden cat populations.

Niger State is a state in the North Central region of Nigeria, bordered to the east by Kaduna State and the Federal Capital Territory, to the north by Kebbi State and Zamfara State, and to the south by Kogi and Kwara states, while its western border makes up part of the international border with Benin.

The Kainji Lake as well as the Niger and Kaduna rivers are the state's major water bodies, with the River Niger flowing through from Kainji Lake through the western part of the state and forming the border with Kwara State. Niger State is also home to the Kainji, Jebba, and Shiroro Dams, which are major sources of hydroelectric power. Also situated there is Kainji National Park, the largest National Park in Nigeria, which contains Kainji Lake, the Borgu Game Reserve and the Zugurma Game Reserve.

The North Central (often hyphenated to the North-Central) is one of the six geopolitical zones of Nigeria representing the majority of the country's Middle Belt. It comprises six states – Benue, Kogi, Kwara, Nasarawa, Niger, and Plateau — in addition to the Federal Capital Territory.

The North Central stretches across the whole width of the country, from the border with Cameroon to that with Benin. In terms of the environment, the zone is dominated by the Guinean forest–savanna mosaic, with the western portion falling into the West Sudanian savanna ecoregion. Plateau State is also named for the Jos Plateau, which lies in the east-central portion of the zone.

In the centre of the state is part of the Chad Basin National Park, a large national park that contains populations of black crowned crane, spotted hyena, patas monkey, and roan antelope along with transient herds of some of Nigeria's last remaining African bush elephants. However, a section of the park, the Sambisa Forest, was taken over during the Boko Haram insurgency in the early 2010s forcing many fauna to flee; large animals were not seen until 2019 and 2020 when a massive herd of migratory elephants returned to Borno.
