Abstract: Soil is an irreplaceable natural resource, with irreplaceable ecosystem functions. One of the greatest risks of soil degradation in the Czech Republic is accelerated erosion, which causes numerous damages to soil properties with negative impacts on the environment. The climate development in recent decades and its forecasts may further intensify these processes. This article deals with the analysis of the impacts of changes in selected climatic factors on the development of erosion processes, which in the conditions of the Czech Republic are influenced mainly by the development of precipitation in the growing season and the development of the values of erosion potential of water released by snowmelt in the winter (non-growing) period. The analysis was carried out on a total area of 459.5 km2, in different morphological and climatic conditions. The impact of climate change was assessed using historical and updated values of rain erosivity and snow erosion potential factors. The results show an increase in the risk of erosive loss in the growing season for all the analysed areas, while the values of erosive loss in the non-growing period differ from each other depending on the climatic and morphological conditions of the areas under study.
