Pianificazione ambientale e paesaggistica nell’area metropolitana di Torino. Nascita e sviluppo di un’infrastruttura verde 1995-2015

Previously known as a one-company town, and then become a post-industrial shrinking city, Turin reacted by embracing a new urban model of sustainable development: the regeneration of brownfield, of degraded and periurban areas was the effect of a landscape project at large scale. The aim of this article is to show how a city region developed a system of blue and green networks, so enhancing the quality of its environment and the quality of life of more than one million people. How the idea of a network of green spaces was conceived, planned and implemented during the last twenty years, thanks to a process of strategic planning and governance, will be analysed, focusing on the planning tools, and their interrelation at different scales, ranging from the urban scale up to the metropolitan and regional level. The implementation of this ‘green’ vision is now opening new perspectives and opportunities, but also questions how to manage a supra-level infrastructure in a systemic way
