The matter of the book encompasses very different issues concerning policies affecting the city's socio-ecological system, namely the efforts to shape it as environmentally and socially sustainable as possible. The definitive message of the book avoids simplistic generalization of green urbanism approaches: indeed the definition of site-specific knowledge and place-based policies is invoked as – probably – the main “green” principle in city planning and green urbanism.
