Procesos urbanos, pobreza y ambiente, implicaciones en ciudades medias y megaciudades

The urban space arises as a social need of the sedentary man, at the same time as an opportunity for settlement, coexistence, identity and lifestyle. These spaces throughout their evolution have been accompanied by the pressure exerted by the economic models themselves and their reproduction needs. On the one hand, the current urban development model exhibits the pressure derived from fragmentation and polarization processes arranged through clusters with different land uses, forms and diverse flows (housing, industry, shops, services, equipment, infrastructure) that affect in the construction of the same urban space. On the other hand, the population enclaves account for the socio-spatial segmentation through the consolidation of socioeconomically heterogeneous human settlements and of different residential typology that, in addition to contributing to urban morphology, also contributes to the forms and quality of life , as well as in the processes of functionality of the cities and in the challenges that from the planning and ordering of the territory arise.

This work investigates some urban and peri-urban problems in the context of Mexico. Although the works address a Mexican situation, it is important to point out that the results and connotations of each research work present in this work lead to raise and / or reformulate reflections and questions about the theoretical foundations, as well as the mechanisms, processes and urban models that prevail in the vast majority of Latin American cities. In this context, the content was divided into nine chapters, which provide theoretical-conceptual views on issues such as poverty, periurbanization, territorial management or social capital, or several of the investigations presented here are applied through case studies such as Mexico City, and the middle cities of Morelia and Querétaro.
