To supply water through ditches, pipes, or canals to areas without water for growing crops

• Desertification

• Irrigation

• Poor sanitation

• Economic development

Poor water quality in Africa

• is mostly a result of industrial pollution

• can be solved by irrigation in Africa's dry areas

• is mostly a result of sewage and garbage

• can be solved by building more dams

Desertification is CAUSED by

• deforestation, drought, and overgrazing

• crop rotation, fertilizers, and insecticides.

• overpopulation, migration, and decline.

• sewage, parasites, and poor sanitation

Slash and burn agriculture is mainly harmful to Africa because it

• pollutes the soil used for farming.

• causes deforestation in the rainforest.

• worsens the unequal distribution of water.

• increases the number of parasites in the rivers.
