Factors that Influence the Payment for Hydro-Ecosystem Services of The Chumbao River Micro-Basin

Abstract

The objective of this work was to evaluate the factors that influence the availability of economic payment of irrigation users for hydro-ecosystemic services of provision to improve conservation actions of the Chumbao river micro-basin. For this analysis, the Contingent Assessment Method was used through logistic regression analysis. The procedure begins with the application of 310 surveys to irrigation users in the communities of the Chumbao valley - Apurímac region. The results were analyzed with the statistical test criterion P <0.05, finding 4 of 5 factors that affect the payment for hydroecosystem services; and in turn, with the 98.11% predictive model, it was determined that irrigation users are willing to pay a monthly fee of s / 2.00. Finally, the factors: hypothetical amount, level of education, water quality and quantity index, and number of members per family significantly influence the availability of payment.
