It is surely of interest to liven up the debate on a concept. Nothing is more pointless than having some principles stated in a book with no practical application of them. Naturally, very often the implementation stage generates disagreements. It is useless for some social movements and inevitable for some others, while some people do not use the term but concretely apply its components. Some, however, use the concept in order to alter the emancipatory potential Henri Lefebvre had thought out.

How can we clarify it? How can we understand what the operators claiming the right to the city actually want? And, how do we connect the militants, researchers and local authorities who, without talking about it directly, try to achieve this essential utopia, the right to the city?

This publication is a result of all of these questions, thanks to all the author’s contributions.
