Badlands (waste lands) are the most expressive form of surface devastation in the landscape. Erosive processes together with destructive activities of the man (deforestation, grazing, forest fires, nonappropriated technologies of ploughing etc.) are the main factors of badlands origin. The paper is concentrated on analysis of origin and classification of badlands as well as on quantification of their areas in Slovakia (about 225 thousand ha) and soil erosion rate on their surface (retreat of slopes due to influence of erosion processes varies from 1.4 to 31 mm yearly on average in relation to geological setting, inclination, altitude and type of badlands). Badlands are the most widespread (65 %) on carbonate bedrocks in Slovakia, but they are present also on the flysch, neovulcanic bedrocks, on loess loams as well as on silicate and carbonate rocks above the timberline. The author anticipates further development of badlands in connection with the global climate change.
