ECOLOGICAL-ECONOMIC (ECO-ECO) MODELLING IN THE MOUNTAINOUS RIVER BASINS: IMPACT OF LAND COVER CHANGES ON SOIL EROSION

Abstract

The research results show that the application of the Eco-Eco modelling, by using the IntErO model for studying the effect of soil erosion and possible land use for intensive seed potato production in the selected River Basin provides cost effective solutions for the benefit of the local population. The objective of the present research was ecological-economic modelling by using the IntErO computer graphic model to simulate soil erosion scenarios associated with intensive seed potato production at one of the sub-basins of the River Lim in the Northeast Montenegro: Bijeli Potok River Basin (2.9 km2). 7.Pinetum peuces: a. Pinetum peuces montenegrinum Blec. between 1800-2000 m; b. Pinetum heldreichii-peuces Lak. between 1700-2000 m; c. Pinetum mughi above 2000 m. According to our analysis, the coefficient fs, (part of the river basin under forests) is 0.50, ft (grass, meadows, pastures and orchards) is 0.42 and fg (bare land, plough-land and ground without grass vegetation) is 0.08. The reason for introduction of seed potato production is economic valuation of natural resources at the observed area. Because of the introduction of seed potato production it was necessary to balance out the increased soil erosion at the area.
