Abstract

En el presente trabajo se simula la introducción de diferentes métodos de reparto del agua en la agricultura, y se aplican a una zona de regadío del valle central del Ebro. En concreto, se han escogido tres métodos diferentes de asignación con el fin de comparar su eficiencia económica. Además del actual sistema proporcional y el sistema de mercado, se simulará la introducción de la regla de reparto uniforme, desarrollada en la teoría de la elección social. Los resultados permiten concluir que aunque el mercado de agua conduzca a mejores resultados globales en todos los casos, la regla uniforme puede resultar una alternativa interesante cuando las dotaciones de agua se encuentran en el intervalo habitual, mientras que en situaciones de escasez severa de agua, el mercado presenta una ventaja más clara con respecto a cualquier otro sistema de asignación. Asimismo, los resultados demuestran que los niveles superiores de heterogeneidad entre los usuarios y altos precios administrativos del agua representan situaciones más ventajosas para la aplicación de la regla de asignación uniforme en comparación con el actual sistema proporcional. Palabras clave: agricultura, gestión del agua de riego, mercado de agua, elección social.
