The savannah ecosystem is a delicate balance of interdependent relationships between different species. This balance is easily disrupted by any human intervention, and the smallest change can have knock-on effects on other people, animals, plants and the wider environment.

Desertification

The effects of drought in Namibia

Desertification can result from poorly managed human intervention in the savannah. Areas of desert are created by the destruction of natural vegetation. Causes of desertification include:

  • Removal of vegetation cover.
  • Overgrazing.
  • Uncontrolled fuel wood collection.
  • Unsustainable farming practice and loss in fertility of soil.
  • Excessive tree felling.
