Environmental Issues of Africa
2
Clean Water

• Many do not have clean drinking water
• Nile River is contaminated with human and
  industrial waste
• Most people in Egypt live along it

3
Aswan High Dam

• Allows Egypt year-round irrigation
• Farmers grow crops 3x a year
• Also used to produce electricity
• The Nile no longer floods, leaving silt on the
  land

4
Irrigation and the Nile

• Because of dam Nile does not flood
• No silt (rich topsoil) is left on the farm lands
• Farmers must use chemical fertilizers
• Problems with fertilizers
• Pollutes the rivers
• Fertilizers have caused some parts to have high
  concentrations of salt
• High salt land is no suitable for growing.

5
Niger River

• Transportation route
• Where it meets the sea it is called Oil Delta
• Area is rich in oil
• The river silt is good for growing

6
Congo River

• Provides water for
• Villages towns
• Irrigation
• Fishing
• Transportation
• Much of the wood from the Rainforest comes down
  this river

7
Clean Water

• Needed for health and sanitation
• Dirty water diseases
• Lack of clean wash water skin and eye
  infections
• Water-borne diseases spread by parasite

8
Factories

• Factories help economy jobs
• Factory waste is sent down rivers
• Gov ignores problems
• Factory workers and citizens harmed

9
Deforestation

• Trees are important because
• Produce oxygen -Paper
• Maintain ground soil -Heat
• Cool the ground -Building materials
• Prevent erosion -Home for wildlife
• Produce food
• Fruit
• animals

10
Deforestation

• Cutting down trees in large amounts destroys the
  ecosystems
• Some areas will never grow back
• Kills wildlife and forces extinction
• Cutting trees in savannas and rainforests

11
Desertification

• Spreading of the desert
• As trees are cut down they dont grow back
• The desert takes over
• Less food is produced for the people
• Resulting in famine (no food to eat)
• Famine starvationdeath

12
Desertification

• Deserts are taking over valuable farmland in the
  Sahel and the Savannas
