Environmental and economic effects of investments in sustainable land management in the basin of Šutilovac stream

This paper presents the results of an erosion processes research on the territory of the morphological unit of Sutilovacki stream, the prevention measures of same processes, as well as the justification of socio-economic investments and a sensitivity analysis of the economic efficiency parameters. The research includes a period from 2017-2032 year, whereby the evaluation methods of professor Gavrilovic are applied in erosion process intensity assessment, on the whole research area, and universal soil loss equation - USLE, on the agricultural land area. Different rates of soil erosion vulnerability are established on the whole research area by applying these methods. Present erosion processes are prevented by the predicted model of future production from the aspect of soil resource protection in the area of the city of Belgrade, by professor Zlatic (1994). Erosion soil losses are significantly diminished and reduced under a tolerable limit, along with the accomplishment of socio-economic justification of investment, examined by the dynamic methods of internal rate of yield, term for the repayment of invested funds, cost-benefit ratio, and net present value. In addition, an analysis of internal rate of yield sensitivity and term for repayment of invested funds are executed. The obtained data indicate justification of the investment.
