GPS/GIS-integrated approach to the assessment of current soil erosion by water – experiences from Mediterranean NW-Syria

Abstract

The assessment of site-specific soil erosion and the detection of its causes are preconditions for the implementation of adapted land use and land management practices. “Soil erosion damage mapping”, a well-tried erosion assessment method, was updated and improved by the integration of GPS and GIS. The method – developed in co-operation between the University of Bonn and ICARDA1 in Aleppo – proved to be helpful in acquiring rapid and detailed information about the current erosion problems. Causal relationships of relief parameters, soil characteristics, land use, vegetation cover and management practices to soil erosion can be detected and analyzed statistically by the use of this method. Based on the findings, recommendations for effective soil conservation measures can be given to achieve sustainable land management.
