This paper with the selection of regional in the western part of the country (the border of the Iraqi state), seeks to examine the role of soil and vegetation degradation in the emergence of dusts. That way, by using satellite imagery and topographic maps, geology and soil ecology, along with field visits and sampling, vegetation maps (canopy percentages, drought resistance, soil protection against degradation And fire authority), soil resources maps (erosion, drainage of soil, maternal materials, soil depth, soil gradient, percentage of gravel, permeability and texture). Then each of the maps was weighted according to the MEDALUS model and in the GIS software, it was prepared as a raster structure and finally by using the fuzzy logic operators, the zoning map of the land degradation scale was prepared on a scale of 0 to 1.The results show that the area can be classified into four very high, medium, low, and very small classes. The area that is in high class has the largest role in the production of dusts in the country, which should focus on deterrence and management in this area.xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx
