This study was conducted to assess soil degradation status in the Abhar-Khorramdarreh Plain. A geopedologic map (soil map) was produced by integration of three information layers including the lithologic, geomorphic, and pedologic characteristics of the study area in the ILWIS environment. Information from the produced geopedologic map, together with the data extracted from the existing soil maps, was used as input to GLASOD approach to assess the susceptibility of soils to degradation. In addition to the above data layers, several other layers including the salinity map, alkalinity map, and land irrigabillity map were also produced to fulfill the requirements of the GLASOD approach. The result revealed that from a total 45,500 ha land areas studied, only 14% showed little or no evidence of degradation while the rest had varied degrees of susceptibility to degradation. Moderately and highly susceptible lands covered, respectively, 6,000 ha and about 17,000 ha. Based on the results, it is recommended to take the necessary measures to combat soil degradation in moderately and highly sensitive areas to ensure sustainable land management in the studied plain.
