La place et le sens contemporain du végétal en ville

Abstract : Nowadays, vegetation seems to have an uncontested place in cities. Vegetation is regarded as valuable for well-being, social link, health, biodiversity, etc. Many rich knowledge exist on the subject but these ones only offer thematic or partial views, which make them difficult to mobilize in practise, especially for urban designing.In order to study urban vegetation and its complexity, a landscape approach has been chosen to have a transversal view on physical aspects (biological aspects included) and on immaterial ones, at different temporal and spatial scales. The methodology develops a diachronic urban landscape analysis on the city of Angers. We also use a research on design approach based on three contemporary urban projects located in Bordeaux, Lyon and Angers. Results show that vegetation, through specific places and precise shapes, appears to be a valuable resource to help solving different urban challenges. Nevertheless, far from being a panacea, vegetation as urban design material and tool, is based on particular knowledge and skills, but also on clear politic choices. We show that vegetation is also a conceptual resource to understand and to conceive urban management. Beyond this, the use of vegetation expresses a complex connection to nature. Urban design choices seem to express contradictory wishes, oscillating between a wish of comfort and neatness, and a wish to leave more space for wild and natural elements. Such contradiction may denote different ethic and politic positions.
