This book presents a great diversity of approaches that make use of the concept of urban fragmentation. Its objective is the understanding of this process, its forms of expression, its causes and effects. In particular, it seeks to understand what question the concept of urban fragmentation tries to resolve. In that sense, this name may be the conceptual answer to the questions that urban researchers have asked. For example, those made by the Americans Marcuse and Van Kempem: is there something different in the spatial pattern of current cities that differentiates them from the cities of before? What would be new in cities and, particularly, in the intra-urban structure? Another of the questions that the concept of fragmentation seeks to answer are those asked by Brazilian researchers Suzana Pasternak and Lucia Machado, in the sense that although cities are in a constant process of internal change, spatial divisions are not a thing either. new, how have they positioned themselves in recent decades? Do they maintain the causes, the scale, the form, the local? Given this context, the book takes up these major research questions and assumes the concept of urban fragmentation as a theoretical and empirical development that tries to provide answers to the questions of contemporary urbanism.
