Description:
Soil erosion by water is one of the most significant forms of soil degradation not just globally, but also in Europe. A new soil erosion risk map of Hungary has been compiled and published recently, using the combined outputs of the USLE and PESERA models. Our study aimed at providing evaluation of the map by using semi-quantitative validation data obtained from the Hungarian Soil Degradation Subsystem (TDR) of the National Environmental Information System (OKIR). The TDR database contained information at farm level as well as indicators based on laboratory data for 5 ha representative plots. Based on the semi-quantitative analysis, the map results align well with the farm-based degradation data, and provide viable information not only at the regional scale, but also at the farm scale. However, indicators from representative plots did not support model results, indicating possible conflict between farm level and plot level data. Cross-comparison of these indicators showed only limited correlation between farm and plot level indicators.
