Resumen
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.
