Finally, by public space, we also designate the concrete formal space accessible to the public, as well as the virtual space of dialogue which indicates the political debate. Public space is the political construction of a common world through debate and dialogue, but it is also a concrete reality, inasmuch as it is a space of life. However, today, in the context of environmental complexity, public space is no longer only the space of debate, it has become the stake of the debate. The question of the environment, i.e. a social question, but also the natural and constructed environment, turns public space into a shared material space which must be debated publicly.
