The subject of this paper is the influence of anthropogenic factors on the state of erosion in the rural part of the municipality of Voždovac. The aim of the research is the anal- ysis of the influence of the local population on land resources, based on the past and present state of erosion and sediment production, the usage of land resources, as well as natural and mechanical population movements. The municipality of Voždovac is one of the 17 municipali- ties in Belgrade area, which covers an area of 15,000 ha. The municipal territory includes both urban and rural parts (9216 ha). When it comes to how land resources are used, it is a charac- teristic example of erosion processes in the mountainous Belgrade area. This paper presents an analysis of the degree of erosion threat to agricultural land in the municipality of Voždovac, including three periods (1971; 1988; 2012), where the method used is the erosion potential method by professor Gavrilović. However, the calculation of sediment yield was made by the method of S. Gavrilović. The analysis of demographic factors pointed to the influence of an- thropogenic factors on the state of erosion. Mathematical methods were used - geometric and exponential progression for population projections in 2020 and 2030. The results of this study showed that the intensity of erosion in that area significantly decreased and that it has a tendency of further decline.
