1. Desertification in AFRICA

2. Desertification
Desertification is the process of fertile, arable land turning into dry, useless land.
Understand that much of Africa that is not already a desert is in danger of becoming a desert.
Agriculture (farming) can only exist on arable land. Arable land is fertile and good for growing crops.
Areas of greatest danger are the Sahel and Madagascar.

4. Desertification Causes – factors contributing to desertification:
Drought: prolonged period without rain.
Overgrazing: animals eat all vegetation.
Deforestation: cutting down trees.
Erosion (wind and water): washes away the topsoil

5. Desertification Effects
Famine: long period of time without food. Usually leads to high rate of disease or death.
Human and animal migration; cities are overpopulated leading to urbanization.
Urbanization is the movement of people from rural communities to urban communities. Urbanization leads to over-crowding, unemployment, crime, and a lack of housing.

6. Desertification Possible solutions include: Restricted grazing
planting trees
agricultural education such as crop rotation.
