The relict high-Andean forest covered by associations of Polylepis Rugulosa found in the arid Andean region of southwestern Peru is a provider of a series of environmental goods and services such as water supply, climate regulation, erosion control, among others, that contribute to the wellbeing of societies. This investigation allows us to know the allocation of a range of economic value of the ecosystem services developed in the study area, based on different perspectives of analysis through the application of the multicriteria model Analytic Network Process (ANP) and the economic estimation of CO₂eq sequestration. The results obtained range from USD 32,641,387 to USD 102,098,052.
