ABSTRACT
One of the key aspects of urban planning is public participation. The way citizens are involved in urban planning can vary a lot in different countries. Even if the number of existing experiments is very limited, I think it is of paramount importance in a modern democracy to offer city-dwellers some tools for, at maximum, designing their future urban environment or, at minimum, to be fully aware about it. In order to reach those ideals, among the problems to solve, let us mention
• Participative plan design, that is to say the way of involving citizens in the design of local plans; one example is the debate concerning environmental and urban planning.
