ABSTRACT

Erosion risk in Poland is generally well recognized. The first country wide map in mid-scale map of potential water erosion risk was produced in '80 according to the qualitative method of potential water erosion risk (PWER) indicator, developed by Anna and Czeslaw Jozefaciuk. The potential erosion risk indicator corresponds to an erosion thread for the soil without any plant cover. It bases on relatively static factors of slope, soil texture and average annual rainfall, distinguishing five grades of erosion intensity. The indicator provides no information on the real and actual state of erosion risk, which depends mostly from the kind of land use. Anna and Czesław Józefaciuk from the Pulawy Erosion Research Center, located in the Institute of Soil Science and Plant Cultivation – State Research Institute, developed methodology for the qualitative indicator of actual water erosion risk (AWER), which includes a land use factor, as well as the factor for erosion prevention techniques.
The work includes the production of an actual water erosion map, based on the digitized map of potential water erosion at a scale of 1:300.000 and CORINE Land Cover 2006. The results show relative high actual erosion risk in highest intensities – up to 1.7% of Poland under the very strong erosion, up tp 0.9% under strong erosion and up to 4.4% under medium erosion. Compared to potential water erosion, where the same grades cover 17.6% of country's area, the erosion risk at high grades decreased by 10.6%. The values are almost identical to the results of AWER assessment performed basing upon CORINE CLC2000 (10), however the general trend is decreasing for the erosion risk grades: 0, 1, 2 and 4; while grades 3 and 5 very slightly increased. According to the land use structure derived from CLC2006, up to 2.18 million hectares (compared to 2.23 million in 2000) remain under the risk of water erosion in high erosion intensity grades and requires erosion control measures.

Key words: soil erosion, water erosion risk, erosion risk indicator, erosion risk map.
