URBAN METABOLISMS. SUSTAINABLE TRANSFORMATION OF THE HISTORIC TOWN

The transformations that took place in the contemporary city have quickly transformed not only the image but also the metabolism of urban spaces. Cities are living in multiple ways, with di erent time frames, use and sharing of space. We live as tourists, residents, workers, artists, musicians and in many other ways. The attractiveness of a city, with its repercussions in economic terms, is closely linked to cultural activities, provision of services, creative content that expresses the tolerance of diversity. The city has become, on di erent levels, a service provider; carried out by public and private entities, or better, in partnership. These services are increasingly being provided within the twenty- four hours, in a continuous cycle that is radically changing the way of life of the users and consumers of the city. Key words and concepts: urban metabolisms, new forms of living, sustainable tourism, urban acupuncture, temporary re-use, greening, densi cation, suburbs, fear, mixité, cultural nomadism.
