Urbanización difusa y consumo de agua para usos domésticos. Una exploración de relaciones
Resumen
En el ámbito mediterráneo, con problemas recurrentes de disponibilidad hídrica, el uso del agua destinada a los usos exteriores de las viviendas unifamiliares, aisladas o adosadas (piscina, jardín, huerto, etc.), resulta uno de los factores importantes para entender por qué este modelo residencial computa unos consumos de agua por cápita superiores comparados con los modelos residenciales de alta densidad. Sin embargo, otras características del modelo urbano y de sus viviendas pueden resultar determinantes para entender y estimar el metabolismo hídrico de estos espacios urbanos residenciales. Este artículo trata de esclarecer cuál es la interrelación existente entre los procesos de urbanización y los patrones sociales en el consumo de agua para usos domésticos, en especial en ámbitos urbanos de baja densidad. Lo hace centrando la atención en la práctica de la jardinería y los diferentes usos del agua en el exterior de las viviendas.Palabras clave
