Based on the theoretical framework of environmental risk, this article discusses the management of air quality in the Autonomous City of Buenos Aires in relation to current and potential impacts of toxic gases and global climate change on the health of the population. Information on historical and current management of the air was linked to the results of the South American Emissions, Megacities and Climate research project to assess danger, exposure, vulnerability and uncertainty as the dimensions of risk. By contextualizing public policies developed in recent decades on this subject, it was possible to identify emerging configurations of risk and uncertainties as accelerators of social vulnerability. On the one hand, the fact that there is a positive correlation between mortality, changes in temperature and air pollution was confirmed. On the other hand, it became clear that there is a disconnect between air quality management and health care management, while limitations were found in the proposed mitigation measures relating to emissions of greenhouse gases produced by fuel, revealing uncertainties regarding their efficacy.

Desde el marco teórico del riesgo ambiental, el presente artículo aborda la gestión de la calidad del aire en la Ciudad Autónoma de Buenos Aires en relación con los impactos actuales y potenciales de los gases tóxicos y del cambio climático global sobre la salud de la población. Se vinculó información sobre gestión histórica y actual del aire con los resultados del proyecto de investigación South American Emissions, Megacities and Climate para evaluar peligrosidad, exposición, vulnerabilidad e incertidumbre como dimensiones del riesgo. Al contextualizar las políticas públicas desarrolladas en las últimas décadas sobre este tema, fue posible identificar configuraciones de riesgo y de incertidumbres emergentes, amplificadoras de la vulnerabilidad social. Por una parte se confirmó que existe una correlación positiva entre la mortalidad, los cambios en la temperatura y en la contaminación del aire. Por otra se constató la desvinculación entre la gestión de la calidad del aire y la gestión de salud, a la vez que se encontraron limitaciones en las medidas de mitigación propuestas en relación a las emisiones de gases efecto invernadero producidas por los combustibles, señalando las incertidumbres respecto a su eficacia.

Este artigo tem por objetivo analisar a vulnerabilidade socioambiental das populações afetadas por desastres, adotando como estudo de caso as inundações ocorridas no Estado de Alagoas, Brasil, em 2010. Para tanto, foram pesquisadas as bases de dados Scielo e Medline, livros, dissertações e teses. Além disso, foram levantadas e analisadas matérias publicadas na imprensa local e nacional sobre essas inundações. Realizou-se também uma visita à Colônia Prisional Santa Fé, localizada no município de União dos Palmares (AL), onde se encontra abrigada parte da população afetada por inundações. A vulnerabilidade resulta, entre outras coisas, de condições de vida precárias dessa população. Mas, mesmo entre os vulneráveis há alguns grupos que se tornam ainda mais vulneráveis, vivenciando sem possibilidades de mudança uma situação de cronificação do desastre, de perpetuação do ciclo vicioso da pobreza e das precárias condições de vida.

The scope of this article is to analyze the social and environmental vulnerability of the population affected by disasters adopting the floods that occurred in the State of Alagoas in 2010 as a case study. For this, research was conducted in the Scielo and Medline databases as well as books, dissertations and theses. In addition, newspaper articles published in the local and national press about these floods were located and examined. A visit was made to some of the individuals who were affected by the flood and subsequently housed in the Santa Fé Prison Colony located in the municipality of União dos Palmares in the State of Alagoas. Among other aspects, the vulnerability is a consequence of the precarious living conditions of this population. However, even among the vulnerable there are some groups that are even more vulnerable without any possibility of changing a situation of chronic repetition of the disaster, perpetuating the vicious cycle of poverty and precarious living conditions.
