Impact de l’artificialisation sur les ressources en sol et les milieux en France métropolitaine

The urban and suburban development is one of the most under-estimated causes of soil destruction. By using tools to characterize land use in the French metropolitan territory, the aim of this paper is to assess the phenomenon of artificialization and its impacts on soils and their environments.
