Planning instruments towards Urban Biosphere

In European cities, the increasing environmental and economic cost of unsustainable cities planning, during the last years, allowed us to obtain a major environmental awareness and to shift the focus on alternative use of urban environment to cope climate change. According to the provisions of the Road Map 2050, 80% of the world's population will live in cities. Urban planning has adopted only recently Sustainable Energy Action Plans (SEAP), taking into consideration clearly separated from urban ecosystems and agricultural. For this reason the author of this study realized a critical review based on the state of the art in the field of SEAP, with specific regards to the relationship with the urban green spaces. This has been considered achievable just through an urban planning proved to be deeply tied to the particular biodiversity a of the involved area, towards the creation of a Urban Biosphere.
