The 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
Ethiopian Highlands in the east. The
Sahel , a belt
of drier grasslands and acacia savannas, lies to the north, between
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.

World Wide Fund for Nature divides the
Sudanian Savanna into two
ecoregions , separated by the
Cameroon Highlands . The West Sudanian
Savanna runs from the
Atlantic Ocean to eastern Nigeria, and the East
Sudanian Savanna runs from the
Cameroon Highlands east to the
Ethiopian Highlands .
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 .
Sudanian Savanna is characterized by the coexistence of trees and
grasses. Dominant tree species are often belonging to the Combretaceae
Caesalpinioideae , some
Acacia species are also important. The
dominant grass species are usually
Andropogoneae , especially the
Hyparrhenia , on shallow soils also
Aristida . Much of the
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.
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
