Vers la ville symbiotique ?

Abstract

Le fonctionnement actuel des villes et des agglomérations se caractérise par un métabolisme qui peut être qualifié de linéaire. Il repose sur d’importantes quantités d'apports extérieurs, en grande partie issus de ressources non-renouvelables, et génère de nombreux rejets non valorisés sous forme de déchets et de pollutions. Face aux multiples conséquences de ce modèle non pérenne, divers axes d’optimisation se révèlent nécessaires pour tendre vers un équilibre à long terme de l’environnement construit. Le concept de ville symbiotique permet de synthétiser ceux-ci dans une vision à la fois intégrée et cohérente, qui consiste à augmenter l’efficacité intrinsèque de la ville, à recourir principalement à des agents renouvelables et, surtout, à valoriser par des cycles courts les diverses ressources cachées au cœur du milieu urbain.

Water pollution

Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources: sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution is either surface water pollution or groundwater pollution.

Groundwater pollution

Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater. This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
