A geographical analysis of the environmental potential and its suitability for agricultural land uses in Kalar district

Abstract

       The study was conducted in Kalar district, south of Sulaymaniyah governorate, between latitudes (˭45 32 º34) and (˭53 ¯09 º35) north, and longitudes (˭13¯ 37 º45) and (˭19¯ 09 º 45) east.  From the research, to determine the spatial suitability of agricultural land uses, it relied on the satellite visual (Landsat 8) with an accuracy of (30 m) and the type of sensor (ETM) on 3/23/2020 to derive the land cover, agricultural land uses, the digital elevation model DEM map, vegetation cover, rain data and population data,  And using the spatial analysis tools in GIS, the Arc gis10.8 program, to build a spatial fit model, six variables were identified (surface, slope, soil, rain, vegetation cover, population) and weights were given to these variables according to the nature of the effect of each variable, then weighted accumulation was done to make the fit  Then, the process of spatial matching between the map of the land cover with the map of suitability to verify the validity of the results.  The research concluded to determine the degree of spatial suitability for agricultural land uses and that there is a spatial disparity in the areas of spatial suitability, and this discrepancy was reflected in the appropriate and unsuitable categories in Kalar district.
