"The book gathers a knowledge about the city from multiple aspects, an undoubtedly impressive knowledge due to its extension and depth, as well as the ability to combine objective data with conceptual reflections regarding the scope and impact of different perspectives about the subject of urban transformation and the different actors that have participated in this process. It's the beginning of a deep and complex reflection, which is both a project of knowledge and an instrument of action and participation ".
