Abstract

En este artículo se estima la curva de demanda de agua de riego en un sistema de regadío a través de la Teoría de Decisión Multicriterio. Para ello, previamente se obtiene la función de utilidad que los agricultores tratan de optimizar, la cual engloba más de un objetivo simultáneamente (maximización del beneficio y minimización del riesgo). Mediante la función de utilidad se realiza una simulación de las decisiones eficientes de cultivo que establecerían los agricultores en el supuesto de aplicarse una política de tarifas sobre el agua de riego. Así se van obteniendo pares de valores (demanda de agua, precio del agua) en función del agua requerida por cada plan de cultivos, que configurarán la curva de demanda de agua de riego. Con la misma metodología se podrá cuantificar los impactos económico, social y ambiental producidos por dicha política de tarifas.....In this article the irrigation water demand curve is estimated by the Paradigm of Multicriteria Decision Making. First of all we have got a utility function that farmers try to maximize and that includes several objectives (profit maximization and risk minimization). By using the utility function we can simulate the efficient decisions of crop set up by farmers in case that a water pricing policy were applied. Thus, pairs of values are established (demanded quantities, water price) in function of the quantity of water consumed by crops, wich conform to the irrigation water demand curve. Through this methodology is also possible to evaluate, in quantitative terms, the economic, social and environmental impacts of the mentioned water pricing policy.
