Optimization of soil use according to the environmental and social restrictions: the case of the Riogrande II basin
Main Article Content
Abstract
The productive activities carried out at the basin of the Riogrande II press (Antioquia, Colombia)
generate negative environmental affections upon the soil and water. The integration of hydrological
and economical models provides a scientific foundation for planned use of the territory that is ratio-
nal and adequate for the actual agricultural vocation. Starting from the data generated by the SWAT
model, the Ecossaut model is reformulated for determining the optimal use of the soil according
to the social and environmental restrictions, finding out that in order to reassure the reliability of
the basin is necessary an implementation of rotation system composed of grass and potato crops
along with a reduction of around 42 % of the soil currently used for agricultural activities.
