Joining the broken down rock is decaying organic living matter such as fallen leaves leaf litter , and dead trees and organisms. Any area of land will support in perpetuity only a limited number of people and if this limit is exceeded without a compensating change in the system of land usage, then a cycle of degenerative changes is set in motion, which must result in deterioration or destruction of the land.

Loss of traditional cultures sil the Masai’s way of life and traditional farming methods have been disrupted by the setting up of the Serengeti National Park. For example, where soils have a high organic matter content and have stable aggregates they are able to withstand the effects of raindrop impact more readily than soils with low organic matter content and unstable aggregates.
