The empty spaces could accommodate houses, parks, factories... they could accommodate a lot of city

The book discusses urban space, with an emphasis on urban voids, questioning the contribution of this element in structuring the urban form of two medium-sized cities. Firstly, it considers that the existence, maintenance, and multiplication of these urban elements, inscribed in their landscape, have been indicative of the production of cities in terms of capital reproduction, to the detriment of a less unequal city that favors life from a social point of view. The work focuses on the expansion of the urban fabrics of Presidente Prudente and Londrina and the proliferation of urban voids, considering, as far as possible, the producing agents that act and benefit from the territorial dispersion of these cities. Through a comparative study, we aim to understand how urban forms, actions, and dynamics develop to produce this element-the urban void. Based on an assessment of the distinguishing characteristics of each city, as well as their common aspects, this movement, which is partly known, will be explained, in addition to understanding the dynamics and implications of the permanence of these empty areas for cities and urban life.
