Valoración económica del servicio de producción hídrica de la microcuenca del Rio Blanco.

Abstract

The main purpose of this research was to conduct an economic valuation of the Multipurpose Service of the hydric supply of the micro watershedof Rio Blanco, in order to contribute to the creation of public politics addressed to the micro watershed conservation. In this context, the Río Blanco micro watershed was characterizedboth, biophysically and socioeconomically. Besides, the values of collection,protection and recovering, the value of water as a supply to the production, operation and administrative costs, were determined. These aspects made possible to understand the real value of water. The main results demonstrated that the representative heading of the sector was livestock, the opportunity cost of USD 233 / ha / year. The relevance of the vegetation covering was 83.5%; the area of water interest was 11,583 Ha almost the 79.86% of the total of the micro-watershed. The volume of available water was 1.97m3, which represents an annual flow of 62,125,920 m3 / year. The value of production or collection was USD 0.036 / m3, while the value of protection 0.00000021 / m3, and the value of recovery was USD 0.024 / m3. As a supply for production the value of water reached USD 0.024 ha / m3. The value of operational and running costs was 0.024 ha/m3, the real value of water is USD 0.08 / m3, if this collection were made to the families of the drinking water boards of the micro-watershed, it would generate about 69,505.34 annually. This research proposes a provincial ordinance through which the autonomous municipal governments feel under pressure to start carrying out economic valuation processes, and enable to chargethe value of water. The resource generated from these charges will be used to generate compensation mechanisms for the owners of the micro watershed, which will make possible to take care of water, and ensure it for the next generations.
