Permanencia y cambio en la percepción de los peligros urbanos

Abstract

This paper explores changes and permanence in the perception of environmental hazards of the inhabitants of the city of Mexicali, Mexico, from 2011 to 2016. The analysis is based on a previous study that identified an amplified perception of hazards as an effect of their physical manifestation at the site and predicted the attenuation of perception as the supply of stimuli decreased or ceased. This work takes into account this assumption to contribute to the analysis of a broader path on risk perception in the city with emphasis on its dynamics and temporality. For that purpose, the information from two local surveys about the dangers that inhabitants recognized in the place was compared and based on indicators of change, the permanent and changing hazards in social perception were identified, as well as their physical manifestation in the city. As a result of this analysis, a significant decrease in social which may result in the reduction of preventive measures and safety practices in urban homes.
