Deforestation:

The result of cutting down trees to use for money & free up land for farming.

**Problem: Cutting down trees leads to erosion (wearing away) of the land & leaves it useless for farming (raising livestock) & agriculture (growing crops).

**Problem: Destroying the rainforest areas & disrupting the natural balance of nature. (Both flora (plants) & fauna (animals) are becoming extinct.)

water issues etc
Water Issues, etc…
  • Farmers depend on chemical fertilizers to grow crops
  • These chemicals end up polluting Africa’s water systems (rivers & lakes).
  • People tend to live near waters systems, especially in Africa, due to the extreme dry conditions in much of the continent.
  • Limited access to water explains the low population in the Sahara Desert.
desertification
Desertification
  • Africa suffers from extreme drought (no rainfall)
  • Drought leads to the problems of:

FAMINE (EXTREME shortage of food) & DESERTIFICATION(spread of desert-like conditions) which makes farming impossible. (Also caused by over-grazing & cutting down trees=OVER USE OF LAND BY HUMANS).

  • The Sahel is slowly turning into desert (desertification).
  • The Savanna is slowly turning into the Sahel.
  • Before long….most of Africa could be a desert!
