Formulación de medidas encaminadas a la restauración hidrológico forestal de la subcuenca laguna de Suesca (Cundinamarca)

Abstract

In this work, measures were formulated to contribute to the hydrological-forest restoration of the Laguna de Suesca sub-basin, for this purpose a diagnosis of the socio-environmental conditions was made through social mapping workshops carried out in the El Hatillo and Ovejeras villages, the state of vegetation cover under the Corine Land Cover methodology and the water behavior of the sub-basin through the water balance and the multitemporal analysis of the changes in the Laguna's water mirror. As a result of the participatory diagnosis, it was identified that cattle ranching, agriculture and mining are the main causes of the current state of the sub-basin, and the lagoon is considered by the population as the central axis of life. Regarding vegetation cover, it was determined that clean pastures occupy most of the territory with a percentage of 60%. On the other hand, it was identified that the sub-basin is in water deficit and the water mirror has been reduced by 57.06%. For the prioritization of the areas to be intervened, the EDANA - C methodology was used, where areas were categorized by environmental damage, so that low damage was 26 %, medium damage was 56 % and the remaining 17 % presented high environmental damage. In accordance with the above, measures aimed at hydrological-forest restoration were designed for the recovery of forest cover, implementation of a community nursery, bioengineering works (trenches) and silvopastoral systems (live fences and protein banks).
