Mountains and desertification, the social and economic reasons and consequences
Abstract
The population of Globe exceeds 6 milliard people. Till now the history did not know such fast rates of growth of the population. In the current times, the growth rate of world population is app. 80 million people per year. Very soon, we may await a problem of maintenance of mankind resources and especially high – quality food stuffs, fresh water, ecologically pure regions for rest and recovery of health.
In the Central Asia republics and Kazakhstan also, the history doesn’t know such fast rates of growth of the population. Physico – geographic conditions of the Central Asia are very variable. In many parts, there is an intensive human activity, which has led to meso – scale changes of a climate, desertification, and air pollution at transboundary scale. (e.g. Aral sea, Fergana valley, etc.).
Desertification is one of the largest ecological, social and economic problems of the current times. Desertification is degradation of the grounds in droughty, half – arid and dry subgumed areas as a result of action of various factors, including change of a climate and activity of the people. Changes in climate cause deficiency of water resources. Other determining factorof desertification is the anthropogenous impact.
