Qualitative and quantitative changes of agricultural land resources in the Czech Republic after 2000.
Gebeltová, Zdeňka ; Boháčková, Ivana (advisor) ; Jarmila, Jarmila (referee)
The main aim of the dissertation is to quantify changes in agricultural land use and propose some solutions to reduce or compensate for quantitative and qualitative degradation of the agricultural land resources in the Czech Republic. Data (WTO, FAO, CIMSC, RISWC, CSO, FADN) are processed by the geographic associations index, environmental stability index, regression and correlation analysis and multi criteria analysis. The quality of the agricultural land is decreased in southern Moravia and central Bohemia (Voltr, 2012).
The quality farmland is mainly reduced in agriculturally valuable soils, i.e. for soils with higher average official price. There is the largest quantitative loss of farmland above all in South-Moravian region and Zlín Region. A distinction of five soil quality classes is made. The large amount of land falls from the highest classes of protection in those two regions. The cultivation of certain crops (wheat, barley, canola, corn, perennial forage, permanent grassland) is located without scant regard for the production of soil conditions. It is not a good way from the agronomical perspective in the Czech Republic. Homogenization of arable crops and their range adversely can affect the long-term productive ability. Although above average high percentage of leased farmland is in the monitored regions, its influence on the GARE change was not statistically confirmed. The irrigation systems should affect the quality of agricultural land. However, the construction of new irrigation systems and the usability of many existing systems is economically limited and influenced by form of ownership too. Subsidies for the sustainability of the production capabilities of agricultural land (Rural Development Program) are paid not for prevention, but as result of erosion processes only. In the dissertation was created multi criteria analysis includes criteria, which can be potential causes reduction of the soil quality. They can simultaneously act on the degradation of agricultural land.
