The Syrian steppe occupies an area of about ١٠ millions hectares representing ٥٥٪ of the country. Due to the relatively high rainfall averages the steppe is known as one of the best grazing areas in the Arab World. This picture however has been ch anged in the recent decades due to the expansion of rainfed barley cultivation and consequent destruction of the natural shrubby cover by tillage. Other reasons leading to land degradation is the steppe overgrazing and shrub cutting for fuel . High soil erodibility is caused by the week structure and light texture of the soils of the steppe. As a result wind erosion became a prevailing process in the steppe. This phenomenon was remarkably accelerated during the last decade. Dust, dust storm, sand accumulation on roads, railroads, villages houses, formation of sand sheets with different thickness and sand hummocks around shrubs were the main environmental features consequences.
