Valoración del agua de riego por el método de precios quasi-hedónicos: Aplicación al Guadalquivir

Abstract

The valuation of natural resources is a tool used for improving allocation and management of water resources. This research proposes a «quasi-hedonic» approach as a simple way for estimating the value of irrigation water. Water is considered here as an exogenous variable impacting on land price, which is estimated for the Guadalquivir River Basin (Southern Spain). Results show a capitalized water value in the range 2.8 €/m3 to 4.2 €/m3. The most frequent value is 3.46 €/m3, resulting in a value of water rent between 0.14 €/m3 (r = 4%) to 0.35€/m3 (r = 10%), depending upon the applied discount rate.
