One of the most important ecosystem services provided by high Andean ecosystems is water regulation; however, these are degraded and their management faces barriers to the availability of economic resources. Therefore, it is necessary to optimize scarce resources through measures that generate greater benefits in terms of water provision. The objective of this study is to evaluate the cost-effectiveness of high Andean ecosystems management in water regulation of the Rontoccocha basin, and then to compare it with other regulation alternatives: construction of rustic micro-dams, concrete dam and payment of the opportunity cost of the families that inhabit the basin of interest. To do this, the effectiveness of the four regulatory measures was first determined; then, each measure was evaluated with the Incremental Cost-effectiveness Ratio estimator and; finally, for the choice of the profitable option, the Cost-effectiveness Threshold was established. This last aspect was determined by the Willingness to Pay of the population of Abancay that contributes to the Payment for Water Ecosystem Services fund in the Mariño basin. The cost-effectiveness threshold was estimated at S / 0.20 / m3 of water, while the incremental cost-effectiveness ratio of the evaluated strategies were: i) restoration of ecosystems through a public investment project (S / 0.35 / m3), ii) construction of rustic micro-dams (S / 1.89 / m3), iii) construction of a concrete dam (S / 0.71 / m3) and iv) payment of the opportunity cost (S / 0.04 / m3). Therefore, considering the threshold, only the fourth alternative is considered profitable since it represents what the Abancay population can finance. The results offer relevant criteria to be able to economically evaluate environmental projects in a context of budgetary restriction and payment schemes for water ecosystem services.
