Fringe-belt analysis in France :<br />A Conzenian approach to urban renewal

This study is based on the fringe-belt model, tested on Nantes and Rennes (France). The model stresses the alternance of high and low density zones (fringe belts). Formerly at the edge of the built-up area, they are now embedded within it. Their formation and evolution are analysed. This model is used with GIS and considered in relation to the recent French law on Urban Solidarity and Redevelopment which encourages compact city policies, calling low-density fringe belts areas into question. The evaluation of the model could shed new light on the French decision making in urban planning, in relation to urban renewal (renouvellement urbain).
