Valoración económica ambiental del servicio hidrológico de la Microcuenca del Río Cebadas del Cantón Guamote, provincia de Chimborazo

Abstract

It was raised to estimate the environmental economic value of the Hydrological service of the watershed of Cebadas River, for that the morphometric, social and environmental characteristics were determined; using contingent valuation method the willingness to pay (WTP) for hydrological service and design of a proposal for the implementation of polices of payment for water services was determined. The methodology was based on empowerment processes and social involvement, for that cartographic tools were used in the Arc Gis 10.2.1, as well as the application of the methodology to raise information of floristic composition, structure and diversity of vegetation, hydrometric analysis of binary logistic regression in SPSS. For designing local policy for charging for hydrological service, guide REMURPE, 2007 was used, focused on the analysis of the problems and the approach of programs and projects. The results show that the watershed is represented by the 83% of paramo with great erosive potential, encompassing 27 indigenous communities, the water supply is 16,65 m³, the water demand of 7 m³, there is a shortage index of 53,30%. The non-acceptance of the WTC is represented by 100%, while the WTP by 96% with a value of 12.00 dollars / year, with a 98.8% of probability of real payment. Sustainable management of the watershed of Cebadas River is determined in eight policies, six programs and twenty-four projects under the sustainability approach. To achieve the proposed goals is recommended that the project be clearly participatory.
