According to recent changes in the Italian Law, several cities must face off their metropolitan dimension and provide a new plan for this area. I am interested in recent experiences and examples which started form another point of view, based on local cooperation and voluntary actions for setting up scope-based associations, as well as multi-puropose associations of municipalities, that can became a forum and/or a strategic table in which discuss the management of wider areas and work on a common vision/strategy for a large territory. Especially I would like to know samples related with tourism, transportation, urban sustainability and metabolism experiences, but also other kinds of focuses are warm welcome.
