This workshop attempted to restart thinking on geographical areas affected by settlement dispersion or sprawl, in the light of phenomena which seem to place question marks over the social and economic assumptions behind these urban forms. More specifically, the decrease in the role of the self promotion of property and the development of housing preferences are currently generating new segments of demand and they are leaving a large number of underused buildings on the land. The workshop considered hypotheses for intervention that are alternatives to the densification projects developed in the nineteen nineties and put forward a working agenda, the terms of which address the question of infrastructures, the redefinition of public transport, a change in settlement composition through building loans and the re-use of emerging abandoned areas to provide diffuse urban areas with services and community areas.
