Introduction: Mountain ecosystems are particularly sensitive to the impacts of climate change, which, in turn, affect the wellbeing of local populations. In this context, the sustainable use of ecosystem services is crucial to supporting the social and economic welfare of Andean communities in South America. The development of local ecological knowledge has facilitated both environmental adaptation and strengthened environmental awareness. Particularly, the qocha, an ancestral water-related agricultural technology, provides hydro-social value, and represents a local climate-change adaptation measure, however their ecosystem services valuation has not been integrally performed. Thus, we aimed to map and assess the perceived services associated with Yuyuchaqocha, a small reservoir managed by a high-Andean community characterized by pronounced economic poverty. Methods: The methodology incl...
