Evaluation of estimates of soil erosion risks on a European scale
The increasing availability of data on a regional scale concerning climate, topography and land use has recently led to the development of models for calculating soil erosion risks on a European scale. It is important to evaluate the accuracy of such estimates, which could be used in the context of soil protection. However, this is relatively problematic at a European level, because it is very difficult, not to say impossible, to obtain direct measurements of soil erosion for large zones. That is why indirect measurements of soil erosion, derived from the amounts of sedimentation in reservoirs in Belgium, the Czech Republic, Italy and Spain, were used to calculate the accuracy of soil erosion estimates produced by three models, USLE, INRA and PESERA. The results show that none of the three models provide precise estimates of soil erosion risks for all European environments when using data at a resolution of 1km x 1km.
