Creating the circumstances of emergence of urbanity in urban «fringes» Case of B

Resumen

The concern of Algerian experience in terms of re qualifying, depend on the choice of a vision that is evolving towards the renewal of tools and methods of intervention (la Documentation Française, 2001). This vision wishes to be a response to failing previous strategies because it wants, first, to impulse a harmonious urban and economical development and secondly, to establish social cohesiveness. The vision aims to promote the valuation of urban fringes (LEMONIER and REMY J. 2005) for their insertion and contribution in urban continuity, especially in terms of quality of place (LÉVY A and SPIGAI V.92) and quality of life. Beside, current urban instruments as PDAU and POS, until now, have not been able to provide urban landscape quality, because of lack of institutional relay. Also, they have not been able to articulate architectural multiple scales and all fields (social, environmental and economical) that concern the act of building. Consequences of this situation are: incoherence of urban landscape, decay of built places and, of course, living places.Starting with a declaration of failure, visible in the breaking of space production, we are proposing a new territorial strategy while searching urban and environmental quality. The main issue is based on the important knots between all dimensions of urban system while acting in transversal actions in order to start a credible compromise in the re insertion of urban design prerogatives (RIBOULET.P. 1998). Actually, its position, between urban planning and architecture (J.P. LACAZE, 1996), allows it to: set relevant perimeters, articulate the territorial and architectural scales and establish relays between different procedures. For example, sustainable development strategy is an alternative to the lack of social factor, wasting of territories, natural resources and urban environment damages. Our research action, rather multi-disciplinary, multi-scale and multi-dimensional, helped us elaborate a frame of quality evaluation that enlightens indicators (IFEN 97) and enables to find a target for levels of failure in order to intervene with relevance and efficiency.
