Changes of the intensity of Ljig river basin erosion: Influence of anthropogenic factor

Abstract

According to new field investigations as well as mapping of erosion in Ljig river basin we have found out that its intensity has changed in regard to period of 40 years ago. The most expressive changes were noticed in Ljig river basin. As we have not noticed changes in physical-geographical factors the cause of the intensity decrease might be only influenced by indirect anthropogenic factor. Processes of growing old and decrease of rural population, migration village-town, marginalization of agriculture and decrease of cattle reserves caused the changes of land utilization. Agriculture areas were becoming overgrown with growing wild vegetation which restrained gradually considerable expressed processes of erosion in the past.
