One of the large problems facing the fauna of the African savannah is illegal poaching. Elephant tusks and Rhino horns are very valuable on the black market. The savannah also faces agriculture related issues such overgrazing, and the clearing of native grasslands to grow crops.
Woody regrowth in savanna systems is environmentally desirable to control erosion, supply fuel wood and sequester carbon but farmers dislike regrowth in their fields as it reduces the grazing potential for cattle.
There are actually many factories, mines, houses and farms there, and so air pollution also one of the main threats to Africa’s savannas. The air can be polluted by smoke and exhaust fumes.
