Riesgo por inundaciones en asentamientos precarios del periurbano. Morelia, una ciudad media mexicana. ¿El desastre nace o se hace?

Abstract

During the past decades, cities at risk have considerably increased in number, particularly in developing countries, stimulated by demographic growth and constant urban remodeling. Such parameters are expressed in urban expansion, creating marginal and precarious peri-urban sectors that when impacted by flooding events magnify their vulnerable condition. During the past ten years the city of Morelia has repeatedly shown such problematic due to the increase in precarious populations, which is in turn, is a reflection of the periphera socio-residential characteristics. Therefore, the consequences of flooding tend to be accompanied by different decisions and human conditions. The present work branches off from the correlation of physical and social variables, as well as from the use of a number of methods and tools in order to obtain the needed parameters for the recognition of precarious areas and their relationship with risk of disaster due to flooding
