Abstract

Resumen Nos planteamos como objetivo poner de manifiesto las relaciones que se establecen entre los sectores productivos y el consumo de agua que éstos realizan para generar su producción. Aplicamos el estudio a Andalucía, Comunidad Autónoma del sur de España caracterizada por su escasez de agua, y nos preguntamos si la dependencia excesiva de los recursos hídricos que algunos sectores productivos de dicha Comunidad pueden llegar a tener, podría afectar de forma negativa, no sólo a la conservación y a la calidad del recurso, sino también a la sostenibilidad de la propia economía. Utilizamos una metodología mixta en la que combinamos el análisis Input-Output, con el que definimos un modelo de consumo de agua y a partir de él elaboramos una Matriz de Intercambios de Agua, con la Teoría de Grafos, mediante la cual analizamos las relaciones contenidas en dicha matriz. Concluimos que la especialización económica de Andalucía no sólo no contribuye a la conservación del recurso sino que además podría llegar a poner en peligro la propia sostenibilidad de la economía regional si los dirigentes políticos no asumen estas limitaciones hídricas en la definición de su política económica. PALABRAS CLAVE: Consumo de agua, Teoría de Grafos, Análisis Input-Output. Summary The aim of this work is to demonstrate the relationships established between an economy's productive sectors and the water consumption generated during their productive processes. We study de Andalusian reality, region of the South Spain characterized by its scarcity, and we will examine if the excessive dependence on water resources which may occur in some productive sectors might affect not only the conservation and quality of this resource, but also have negative effects upon the stability of the economy itself. A mixed methodology has been used, combining Input-Output analysis with Graphs Theory. We obtain a water Input-Output model and an interrelationship matrix which is analysed by Graphs Theory. The main conclusion is that Andalusian's economic specialisation does not make a positive contribution water conservation and, moreover, the regional economy's sustainability might be seriously endangered if the authorities do not take into account water limitations in their economy policy.
