Evaluación de la percepción sociocultural de los servicios ecosistémicos en la cuenca del río Orotoy aplicando la metodología de proceso analítico jerárquico-ahp

Abstract

This research evaluated the sociocultural perception of ecosystem services (SE) of the Orotoy River basin (Meta, Colombia), through the hierarchical analytical process methodology (AHP). Initially it was carried out the identification of the SE through a bibliographical review of previous studies carried out in the study area and complemented with the realization of workshops of focal groups with key actors, to define the ones provided by the Natural system, where six were identified (water regulation, food, soil fertility, climate regulation, scenic beauty tourism and identity). Subsequently, semi-structured interviews were carried out to 60 people, where ranchers, farmers (subsistence and medium production crops), oil palm companies and managers with high levels of knowledge of the basin participated; this made it possible to achieve a context analysis of the current situation in the different sections of the basin and the use of the SE. Likewise, it enabled the valuation of the SE according to the criterion of the interviewees through the AHP; to prioritize the we obtained the value of importance (own VP vector) of each one on each other; finally, it related the hierarchy obtained with the sociocultural environment in several scenarios (by sections and type of actor) to complement the analysis of the general prioritization of the basin. It was found that the population interviewed and who valued the were prioritized provision services on the regulations and cultural, where the water Regulation (supplying waters) was classified as the most important in all scenarios, then of food service, climate regulation, soil fertility, identity and scenic beauty tourism respectively.
