Desertification in jordan:A Security Issue

摘要

The existing ecosystems in Jordan are fragile and prone to deterioration. The leading causes of land degradation in Jordan are improper farming practices (such as failure to use contour plowing or overcultivation of the land), overgrazing, the conversion of rangelands to croplands in the marginal areas, where rainfall is not enough to support crops in the long term, and uncontrolled expansion of urban and rural settlement at the cost of cultivable land. Implementation of soil conservation and erosion control measures such as contour plowing, terracing, and stonewall construction on farmer's fields helped in curbing accelerated erosion and in protecting the potential agricultural lands.
