Opis (eng)

Landscape transformation, degradation and destruction are caused by fluvial processes asthe predominant erosive processes in Serbia. The loss of arable land due to riverbankerosion is permanent, and the economic consequences are, therefore, especially pro-nounced. The primary aim of this study was to quantify the intensity of riverbank erosionin the lower part of the South Morava River (Serbia) during period 1924–2020, evaluate itseconomic consequences, and conduct a cost benefit analysis of revetment investments.The economic effects of riverbank erosion were analyzed by means of land loss andreduction in the quantity of agricultural production. An interdisciplinary research approachwas applied using specific methodological procedures to calculate the riverbank erosionand soil (land) loss intensity (geographic information system-GIS), the economic con-sequences of riverbank erosion (ECRE), and the results of an investment decision-makingmodel. The results showed that 202.6 ha of arable land was lost during the observed period,the value of arable land loss was almost 622,000 USD, and the loss in agricultural pro-duction was 7.5 million USD (discount rate 3.7%). The model is seen as the main research output and can be used for the assessment of long-term capital-intensive infrastructureprojects in developing countries. The analysis identified the river segments that are eco-nomically viable for investments in riverbank revetments to preserve the largest area offertile agricultural land. The results are especially valuable for river channel management,environmental planners and policy-makers, who deal with decisions regarding planningand the protection of bank erosion in areas of particular interest.
