Risk urbanism, the principle of urban disasters and their prevention with geo-computerized systems, CDMX, Mexico

The so-called urbanism of risk created the conditions for the inadequate urban planning in Mexico City (CDMX), which affects the populations established there. This term is little known today and should not be confused with urban risk. Nowadays, the incorrect urban configuration creates awareness in the inhabitants about the risks present in their lives, according to the impact of natural phenomena (hazards). It is important to understand that the effects of disasters in urban areas are derived from growth in places with unsuitable characteristics, due to the irregularity of the terrain. Risk is the result between hazard and vulnerability, which becomes urban risk when it affects the established population. The contribution of this article shows that the beginning of the adequate urban configuration based on geoinformatics systems will prevent risk urbanism in areas where there is no city growth yet. As a result, it is shown the crossing of variables provided by governmental institutions and real events occurred, according to floods, landslides, earthquakes and collapse of mined areas, using geoinformatics systems to show the municipalities with greater affectation, according to the existing urban risk, which can be replicated and attended in other parts of the country and the world, based on the management between government, academics and population, with the objective of preventing the creation of risk urbanism.
