Drought and desertification in IRANby Morteza Aminmansour
Desertification means land degradation in arid, semi-arid and dry sub-humid area resulting from various factors, including climate variations and human activities.
Desertification can only be reversed through profound changes in local and international behavior, these changes will ultimately lead to sustainable land use and food security for a growing world population.
Due to IRAN geographical situation and topographical features, about 80% of Iranís total area have arid or semiarid climate.
Land degradation and desertification in Iran have accelerated during recent decades due to the following factors:
Denuded soil is exposed to wind erosion and shifting sand dunes destroy orchards, gardens, farming lands and threaten industrial and economical centers and leads to total collapse of economy, devastation of the environment, abandonment of settlements and migration of people to other cities and residential centers.
The policies and programs to rehabilitate and develop renewable natural resources, with consideration for desertification control are as follows:
Desertification is a global concern not limited to specific geographical regions.
In the case of IRAN: Wind erosion and its effects on natural resources and the environment has been a serious problem in the last 25 years.
Two of the major environmental hazards affecting the planet are deforestation and desertification, in terms of the nature and magnitude of the problem as faced by the developing world including Iran.
More than 250,000 ha of tropical forest are destroyed annually in 14 developing countries in South America, Africa, and South- East Asia.
The expansion of communication, the construction of large dams, the failure to assist the poor, and climatic anomalies of fire and drought only aggravate this problem further.
Global warming and the greenhouse effect, which have their origin in deforestation and desertification.
