Urbanization is the one of the most evident forms of anthropization. With most of the world population living in cities, the need of thinking about a more sustainable urban lifestyle has become an imperative.

Besides that, different communication languages can be used to enhance the development of a shared reflective vision about the future of cities among citizens, as major actors of the urban life and its transformation. This book provides an accessible overview of some key methods to deal holistically with the analysis of urban resources flows to readers with an interest in the academic or professional reference of the different approaches for studying urban metabolism.
