Land degradation by erosion and its economic consequences for the region of South Moravia (Czech Republic)

Popis výsledku v původním jazyce

The quality of agricultural land fund in the Czech Republic is assessed via a valuation system based on the ecological-productive land evaluation. This system was established in the 1960-1980s after a complex survey of agricultural land. It provided integral information on the agricultural land quality and on the price of agricultural land parcels derived from their productive capacity. Starting from the 1990s, evidence in the database of evaluated soil-ecological units (further referred to as ESEU) has been currently updated. Intensive cultivation of wide-spaced crops, namely in extended, largely sloped land parcels, has resulted in degradation of land characteristics by the effects of erosion. ESEU updating enables detection of these changes and their quantification by differences in land price. This approach was applied to evaluation of the economic impacts of erosion in two model localities in intensively exploited agricultural areas, in the region of the most productive soils of the Czech Republic. We compared the price per 1 m2 of land according to the land characteristics determined by the first land valuation with the current soil price based on the ESEU update. We also compared changes in the land characteristics. In the GIS environment, we established the mean long-term soil loss by erosion based on the original ESEU and compared it with the calculated soil loss based on the updated ESEU. The calculation method used was in accordance with the valid methodology for erosion calculation in the Czech Republic.
