Abstract

Resumen Nos planteamos como objetivo poner de manifiesto las relaciones que se establecen entre los sectores productivos y el consumo de agua que ÃƒÂ©stos realizan para generar su producciÃƒÂ³n. Aplicamos el estudio a AndalucÃƒÂa, Comunidad AutÃƒÂ³noma del sur de EspaÃƒÂ±a caracterizada por su escasez de agua, y nos preguntamos si la dependencia excesiva de los recursos hÃƒÂdricos que algunos sectores productivos de dicha Comunidad pueden llegar a tener, podrÃƒÂa afectar de forma negativa, no sÃƒÂ³lo a la conservaciÃƒÂ³n y a la calidad del recurso, sino tambiÃƒÂ©n a la sostenibilidad de la propia economÃƒÂa. Utilizamos una metodologÃƒÂa mixta en la que combinamos el anÃƒÂ¡lisis Input-Output, con el que definimos un modelo de consumo de agua y a partir de ÃƒÂ©l elaboramos una Matriz de Intercambios de Agua, con la TeorÃƒÂa de Grafos, mediante la cual analizamos las relaciones contenidas en dicha matriz. Concluimos que la especializaciÃƒÂ³n econÃƒÂ³mica de AndalucÃƒÂa no sÃƒÂ³lo no contribuye a la conservaciÃƒÂ³n del recurso sino que ademÃƒÂ¡s podrÃƒÂa llegar a poner en peligro la propia sostenibilidad de la economÃƒÂa regional si los dirigentes polÃƒÂticos no asumen estas limitaciones hÃƒÂdricas en la definiciÃƒÂ³n de su polÃƒÂtica econÃƒÂ³mica. PALABRAS CLAVE: Consumo de agua, TeorÃƒÂa de Grafos, AnÃƒÂ¡lisis 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.
