Metabolismo urbano : comprensión entre la ciudad con su entorno natural

Abstract

Las ciudades o áreas urbanas son caracterizadas por la centralización de actividades económicas, una gran población, grandes densidades de materiales en stock, incluyendo altos niveles de flujos de materiales y energía (Niza, 2009); además de grandes problemas de contaminación ambiental. Actualmente el mayor problema que presentan las ciudades es la linealidad de su metabolismo, es decir para su funcionamiento requiere grandes cantidades de materia y energía que son extraídas de un entorno natural, posteriormente son procesados dentro del territorio urbano y finalmente devueltos al entorno natural en otro estado físico. Lo ideal, sería cambiar de un modelo de metabolismo lineal a un modelo de metabolismo circular, donde la ciudad pueda ser autosuficiente, lo mayormente posible, y así comenzar la desmaterialización de las economías. Para entender la relación que tiene la ciudad con su entorno natural, es necesario analizar los flujos de energía y materiales que atraviesan las economías a lo largo del tiempo ((Carpintero Redondo, 2005)). Por lo que el objetivo de este trabajo es cuantificar los flujos materiales de Terrassa mediante la adaptación de la metodología propuesta por (EUROSTAT, 2001) a una escala a nivel ciudad, en el periodo comprendido de 2005, 2007 y 2008. Los resultados obtenidos muestran una gran dependencia con el exterior, así como la heterotroficidad que presenta la ciudad al no ser autosustentable.
