Abstract
La Directiva Marco de Aguas, aprobada en el año 2000, obliga a todos los Estados miembros de la Unión Europea a introducir una política de precios del agua. Por ello se prevé que los subvencionados cánones y tarifas de riego pagados actualmente por superficie regada cambien por tarifas volumétricas mucho más elevadas. En este sentido, el objetivo del presente trabajo consiste en desarrollar una metodología que permita analizar el impacto que tendría una política de precios del agua de riego sobre la demanda de tecnologías ahorradoras de agua. Para ello se utilizan modelos de programación matemática basados en la Teoría de la Utilidad Multiatributo. Esta metodología se aplica de forma piloto en una zona regable de Castilla y León. Los resultados ponen de manifiesto la disparidad de la disposición a pagar por nuevas tecnologías de riego entre los diferentes tipos de agricultores, siendo menor a medida que presentan un perfil más conservador (menor ponderación del objetivo de maximización del beneficio)...European water policy, as set out in the Water Framework Directive (WFD), requires all EU Member States to implement volumetric water pricing at rates that roughly cover the total costs of providing water services. The objective of this paper is to develop a methodology that, for the different farm-types in an irrigable area, will enable us to analyse the differential impact that a pricing policy for irrigation water would have on the demand of new irrigation technologies. For this purpose, Multi-Attribute Utility Theory (MAUT) mathematical programming models have been used. The methodology is implemented on a representative area in the Duero Valley in Spain. Our results show the usefulness of differential analysis in evaluating the impact of a water pricing policy. This allows significant differences in the willingness to pay for new irrigation technologies in the various groups of farmers, being smaller as they present a more conservative profile (smaller weighting of profit maximization objective).
