De la ciudad a la metrópoli: una interpretación teórica del fenómeno expansivo ligado a la vivienda, a la vulnerabilidad y a la pobreza: el caso del área metropolitana de Monterrey... por Sousa González, Eduardo

“…Abstract: At the moment, the urban space represents the main way of demographic and economic concentration, not only in Mexico cities, but also, in almost all the Latin-American ones, and maybe of the world; to understand the way in which these urban spaces transform to “metropolis”, is fundamental to try to affect them in a way, this, by means of the generation of suitable instruments of planning, which will produce operative public policies that avoid the proliferation and occupation of vulnerable spaces. …”
