Real soil erosion risk

The Soil, Environment and Landscape Study Centre of the former ARSSA has developed in collaboration with the CRA-RPS 2 specific environmental indicators (erosion and organic carbon) using data from 1799 georeferenced soil profiles with: altitude, slope, horizons and related granulometric analyses (percentages of sand, silt, clay and organic carbon content) and precipitation data (monthly averages) from 17 rain stations of the national network (source CRA-CMA). The digital model of the land with 30 m resolution (source ASTER) and the soil use paper (source Corine Land Cover) were also used. The estimated amount of eroded soil (t/ha x year) in the regional territory was made using the Revised Universal Soil Loss Equation (RUSLE): The results of the RUSLE were represented as real erosion (i.e. including cover factors and soil conservation practices) and the value assigned to the INSPIRE network cells is the average of the 30 m cell values inscribed in each 1x1 km cell.
