« Zéro artificialisation nette » en aménagement : compter et conter la nature en ville pour changer les pratiques ?

Abstract

To explain the place of nature in cities, many researches focus at the macro-social level (laws, national programs, etc.) and underline the predominance of its commodification. The analysis of the Zero Artificialization of Soil (ZAN) rule as grasped by the urban development social world indicates that nature is the object of such explanatory processes at the intermediate social level (association and professional networks, etc.) and at the individual and local level (projects, developers, etc.). On these two levels, the diverse and competing narratives of urban developers attempt to make sense of ZAN. They adopt the register of quantification and accounting to facilitate the sharing of meanings in this heterogeneous social world. They are not, however, locked into economic frame. The meanings sought are also material, technical and scientific. They activate, around the construction of stories, the transformation of urban development practices as much than the legislative and political frameworks.
