This symposium will deal in particular with totally or partially vegetated urban wastelands, and proposes to question the roles played by wastelands in the green infrastructure, and in particular the differences with other urban green spaces. We can wonder whether brownfields can be considered as informal green spaces and to what extent they can help to change the current perception of urban nature. Three aspects will be considered, linked to three major issues: social, ecological and urban planning stakes.
Les friches font partie du paysage urbain et du quotidien de beaucoup de citadins. Bonthoux et al. Sont-elles en relation avec la dimension de la tache urbaine? Quelles dynamiques urbaines ces friches traduisent-elles?

Very variable in their shape and size, in their place on the urban gradient, in their longevity, urban wastelands are generally present in all cities, whatever their size. Urban wastelands are former cultivated fields encompassed in the city by urban sprawl, or former residential, industrial or services areas, involved in urban renewal or located in shrinking cities. In all cases, the existence of urban wastelands is closely linked to the evolution of cities: they are an integral part of them.
This symposium addresses the scientific community and practitioners. It will deal in particular with totally or partially vegetated urban wastelands, and proposes to question the roles played by wastelands in the green infrastructure, and in particular the differences with other urban green spaces Saint-Laurent, We can wonder whether brownfields can be considered as informal green spaces Rupprecht et al.
