Chapter 6: the soil

What are the effects of soil erosion?
  • Decline/reduction in soil fertility: The fertile topsoil is carried away leaving only the infertile subsoil.
  • Low inadequate food production leading to starvation, and even famine. Widespread poverty of farmers who produce little food.
  • Migration of people from affected areas to less affected areas -Soil eroded by water or wind may be deposited at the bott6m of a slope over fertile, cultivated lands thereby ruining them.
  • Sediments that. Accumulate down slope of the erosion can obstruct the flow of water in streams and drainage canals, leading to flooding.
