Abstract

In this study, the Modèle d'Evaluation Spatiale de l'Aléa Erosion des Sols) MESALES model was applied to 3 large areas in Europe and Morocco, using soil data from the European Soil Database (ESDB) and Digital Soil Map of the World (DSMW) as well as from the newly developed e-SOTER database. Land use data were derived from the Global Land Cover 2000 database, and slope angle from the HYDRO1K DEM. The aim was to evaluate whether the e-SOTER database resulted in better assessment of soil erosion sensitivity than existing data. The comparison of results obtained with existing data and with e-SOTER data showed considerable differences. However, it proved impossible to say which results were better. The fact that the application of different soil databases resulted in quite different results does, however, indicate the importance of using the best available data for evaluation of soil threats. However, a current lack of options to validate soil erosion sensitivity estimates was also identified
