Africa Desertification SS7G2

The Sahel is one part of Africa that is experiencing severe problems with Desertification, the process of the desert expanding into areas that had formerly been farmland. As land is overused, the soil becomes poor and powdery. The winds coming from the Sahara gradually blow the dry topsoil away, leaving a barren and rocky land that loses it ability to hold water.

Cause: Some areas of Africa are to hot
Effect: Africa is in danger of lots more desert land

Africa Deforestation SS7G2

As Africa's population increases and nations try to develop economically, deforestation has become a growing concern. Deforestation is the process of forests being destroyed to make way for human development. The main cause of deforestation in Africa's rain forests today is commercial logging. the timber from the rain forest is exported all over the world and helps boost the economy of many African countries. Unfortunately, the environment, is destroying as a result.


Cause: People are cutting down tress for commercial logging in the Tropical Rain Forest.
Effect: Its hurting the nature around it and less Rain Forest then the less medicine it also hurts the amount of oxygen.

Africa Poor Soil SS7G2

Over a thousand years, hunting, gathering, grazing animals, and small scale farming have made Africa's soil very poor. It started when the European countries took over Africa in the 1800s. they started to export on a large scale. They exported natural resources such as rubber, ivory, timber, and copper. It put Africa into a fragile ecosystem. today most of Africa soil is less fertile then the soil found in other continents.

Infertile soils add to several other problems too. For example, slash-and-burn agriculture is used because of low soil productivity. In this type of agriculture, poor farmers continually clear land which helps speed up deforestation and desertification.


Cause: Europeans took over the land and did there own thing.
Effect: That the soil is so poor in some places that people can't grow crops.
