Resumen
Ecosystem services and their contribution to local economies and livelihoods still need to be fully
understood and recognized by many policymakers. The primary purpose of this research is to
integrate land use and land cover data and local ecological knowledge-based data with
geographical information systems through a participatory approach to enhance natural resource
management. We selected the Pariac-Rajucolta watershed as a study area because it is a typical
landscape in the high-Andean mountains, with half of its territory inside a protected area. The
methods involved a six-month participatory approach quantifying the benefits and exchange
values of 33 provisioning ecosystem services, compiling the primary data from the locals and
spectral information from Sentinel-2A. The results show that only agricultural and artificial areas
delivered multiple benefits and offered the highest commercialization value of ecosystem ser-
vices. The community mainly benefits from nutrition, materials, or energy from cultivated
terrestrial plants, reared animals, wild plants, and surface water at the watershed level. At the
same time, the services with high exchange proportions were mainly short -only meat of guinea
pigs, manure, wild fruits, mushrooms, and wild plants for food. The abundance and the spatial
distribution of benefits and exchange values of ecosystem services displayed a pattern of high
quantity for the downstream and low in the basin’s top and midstream of the watershed (inside
the protected area). In conclusion, the study shows the importance of knowing ecosystem services
benefits and exchange values as an initial approach to developing participatory strategies for
managing and conserving natural resources.
