“…We identified this issue in areas with moderate exposure to PM 10 , where some respondents reported very poor air quality when industries were in the proximity. On the other hand, the sense of attenuation mentioned in [ 82 ] is manifested here as well, since only 14% of the respondents living in extremely high exposure areas perceived very poor air quality. This sense of attenuation, in some cases, is related to the order of priorities that people have.…”

“…In agreement with previous studies [ 27 , 81 ], we found that perceived changes in air quality occur in areas where people are exposed to the visible manifestation of pollution, such as extremely high concentrations of PM 10 . For instance, a previous analysis of the spatial dimension of environmental and social hazards related to the public perception in Mexicali, Ley-García et al [ 82 ] showed that only 23% of their sample showed congruence between exposure and perception. In those instances, where the perception was higher than the exposure, the proximity to potential sources of pollution played a role.…”

Air pollution in developing countries is a growing concern. It is associated with urbanization and social and economic structures. The understanding of how social factors can influence the perception and the potential impact of air pollution have not been addressed sufficiently. This paper addresses the social vulnerability and exposure to PM10 association and its influence on the air quality perception of residents in Mexicali, a Mexico–US border city. This study used individual variables and population census data, as well as statistical and spatial analyses. A cluster of socially vulnerable populations with high exposure to coarse particulate matter (PM10) was found in the city’s peripheral areas. The spatial distribution of the local perception of air quality varied by the exposure zones of the estimated PM10 concentrations. Respondents living in very high exposure areas perceive air quality as “poor,” contrarily to a worse perception in areas of intermediate and lower exposure to PM10. Proximity to stationary sources of pollution was associated with a poor perception of air quality. Results also indicate that low household income and poor air quality perceived at the place of residence negatively influences the perceived changes in the air quality over time. The knowledge of chronic health effects related to air pollution was scarce in the sampled population, especially in the areas with very high exposure and high social vulnerability. These findings can serve as a support in local air quality management.

“…applied a pairwise comparative method in the AHP implemented in the SMCE module of the Integrated Land and Water Information System (IlWIS) software. GeoDa, an open-source software, focused on methods for spatial data has been used by authors who address the topic of spatial association (Gu et al, 2018;Ley-García et al, 2015). The aforementioned programme is an RS and GIS software, on which the robustness of the results from was also tested, with a sensitivity analysis performed in the DEFINITE toolbox implemented in Il-WIS.…”

Abstract. Society and economy are only two of the dimensions of vulnerability. This paper aims to elucidate the state of the art of data sources, spatial variables, indicators, methods, indexes and tools for the spatial assessment of socio-economic vulnerability (SEV) related to geohazards. This review was first conducted in December 2018 and re-run in March 2020 for the period between 2010 and 2020. The gross number of articles reviewed was 27, from which we identified 18 relevant references using a revised search query and six relevant references identified using the initial query, giving a total sample of 24 references. The most common source of data remains population censuses. The most recurrent spatial variable used for the assessment of SEV is households without basic services, while critical facilities are the most frequent spatial category. Traditional methods have been combined with more innovative and complex methods to select and weight spatial indicators and develop indices. The Social Vulnerability Index (SoVI®) remains the benchmark for the assessment of SEV and a reference for its spatial assessment. Geographic information systems (GIS) is the most common tool for conducting a spatial assessment of SEV regarding geohazards. For future spatial assessments of SEV regarding geohazards, we recommend considering 3-D spatial indexes at the microscale at the urban level and involving the community in the assessments.

“…Ambas situaciones han sido catalogadas como desfases perceptuales con respecto a la realidad objetiva que conllevan al incremento del riesgo (Ley, Denegri y Ortega, 2015) e implican un reto en materia de política pública, debido a que quienes no identifican los peligros del entorno, o los juzgan inofensivos e improbables, difícilmente estarán preparados o tomarán las medidas necesarias para hacerles frente (Ley, Denegri y Sánchez, 2016); mientras que quienes tienen una apreciación excesiva de los peligros pueden tener reacciones exageradas (estampidas humanas, caos, disturbios sociales, entre otros) ante cualquier indicio de la presencia de éstos en el lugar.…”

En este documento se exploran las diferencias en la percepción del riesgo que presentan los habitantes de la ciudad de Mexicali, a partir de la clasificación de información obtenida mediante una encuesta que involucra variables relacionadas con el tipo de peligro, las características sociales de los sujetos, la vía de adquisición del conocimiento y las acciones preventivas que se realizan. Entre los resultados se obtuvieron cuatro grupos perceptuales: dos extremos (amplificadores y atenuadores) y dos intermedios (de percepción focalizada o selectiva), cuyas características particulares ameritan ser consideradas en materia de prevención de desastres.
