AbstractWithin Europe, Spain is one of the most endangered countries of potential environmental changes leading to desertification. At present, about 40% of the Spanish territory is seriously threatened by erosion, that specially affects some landscapes in the central part of the Ebro basin. Increasing loss of productive soils is a main concern in some se¬miarid regions of the Mediterranean area. In this work, the 137Cs technique is applied as an approach to examine the environmental impact of erosion and sedimentation on soil and water sustainability in Mediterranean landscapes of NE Spain. This region has a large diversity from the semiarid steppe in the centre of the Ebro valley to alpine mountains in the Pyrenees Range. The role played by land cover and cultivation on soil loss is assessed on representative slopes of the phyisographic variety in central Ebro basin by using the radiometric technique.These case-studies evidence the fragility of Mediterranean agrosystems and the need for establishing land management practices aimed to landscape conservation as in this environment soil essentially constitutes a non renewable resource.
