Les objets de nature : Quelles places dans la ville ? Conditions d’appropriation des dispositifs de gestion des eaux pluviales de la métropole lyonnaise

Abstract : To better manage storm water and to respond to problems related to the sanitation networks conceived in the 19th Century, some alternative techniques, other than networks, are being put forward. The “all tubes” concept is giving way to various technical objects of a hybrid nature made up of natural components and synthesized material. The physical appearance of these “natural objects” is double (both natural and artificial) and they fulfil various purposes. Thus, their insertion in the landscape can be delicate. How are these natural objects seized by society? In this process are any difficulties encountered? How is the place for natural objects defined in a city? The purpose of this dissertation is triple: (1) gather information on the relationship between societies and natural objects, (2) collect data on the public's use and practices, (3) discuss a methodology to study human behavior. Three inquiries were carried out during the four seasons of the year and in twelve sites; they were based on direct observation and systematized photography. Based on the fieldwork and the concept of “genèse instrumentale” developed by Rabardel, a discussion was developed on the building of a natural object as a tool. Subsequently, based on the observation of the public, practices, uses and the conditions in which these natural objects are used were defined. The dissertation concludes by highlighting the advantages and the limits of direct observation, and by developing the biases such as the context in which the data was analyzed, in order to suggest some possible methodological enhancements which could help future studies.
