The Sudanian Savanna
Sudanian Savanna
is a broad belt of tropical savanna that runs east and west across the African continent, from the Atlantic Ocean

in the west to the western lowlands in the east. The Sahel, a belt of drier grasslands and acacia savannas, lies to the north, between the Sudanian Savanna

and the Sahara

Desert. To the south the forest-savanna mosaic is a transition zone between the Sudanian Savanna and the Guinean moist forests and Congolian forests

that lie nearer the equator.

Ecoregion[edit] The World Wide Fund for Nature

divides the Sudanian Savanna
Sudanian Savanna
into two ecoregions, separated by the Cameroon Highlands. The West Sudanian Savanna runs from the Atlantic Ocean
Atlantic Ocean
to eastern Nigeria,[1] and the East Sudanian Savanna

runs from the Cameroon Highlands

east to the western lowlands of Ethiopia.[2] Physiographic province[edit] The Sudanian Savanna
Sudanian Savanna
is one of the three distinct physiographic provinces of the larger African Massive division. Physiography divides this province into three distinct physiographic sections, the Niger Basin, the Lake Chad Basin, and the Middle Nile Basin.[2] Vegetation[edit] The Sudanian Savanna
Sudanian Savanna
is characterized by the coexistence of trees and grasses. Dominant tree species are often belonging to the Combretaceae and Caesalpinioideae, some Acacia
Acacia
species are also important. The dominant grass species are usually Andropogoneae, especially the genera Andropogon
Andropogon
and Hyparrhenia, on shallow soils also Loudetia
Loudetia
and Aristida. Much of the Sudanian Savanna
Sudanian Savanna
region is used in the form of parklands, where useful trees, such as shea, baobab, locust-bean tree and others are spared from cutting, while sorghum, maize, millet or other crops are cultivated beneath.[3] Land use[edit] The Sudanian savanna is used by both pastoralists and farmers. Cattle are predominantly the livestock kept, but in some areas, sheep and goats are also kept. The main crops grown are sorghum and millet which are suited to the low levels of rainfall. With increasing levels of drought since the 1970s, pastoralists have needed to move southwards to search for grazing areas and have come into conflict with more settled agriculturalists.[4] See also[edit]
