- ItemAcesso aberto (Open Access)Análise da vulnerabilidade socioambiental em Cubatão-SP por meio da integração de dados sociodemográficos e ambientais em escala intraurbana(Associação Brasileira de Estudos Populacionais, 2013-12-01) Alves, Humberto Prates da Fonseca [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The paper Population, poverty and pollution in Cubatão, São Paulo (1993), by Dr. Daniel Hogan, was published in the first book written by the Working Group on Population and Environment, of the Brazilian Association of Population Studies (ABEP). Twenty years have gone by since the book and paper were published, and this text is now presented as an updated analysis of the coastal municipality of Cubatão, in the State of São Paulo. It uses results from the Brazilian 2010 Census and is based on concepts and methodologies currently present in the debate on Population, Space and Environment, which are tributaries of Dr. Hogan's contributions. The major objective of the paper is to empirically operationalize the concept of socio-environmental vulnerability by constructing social and environmental indicators. In the process, socioeconomic and demographic data from the IBGE 2010 Census is used, as well as data on areas of environmental risk. GIS and spatial analysis methods are used to analyze situations of socio-environmental vulnerability on an intra-urban scale in the municipality of Cubatão. The results show the existence of intense concentration and spatial overlapping of situations of susceptibility, poverty and exposure to environmental risk in certain areas of the municipality. With reference to Daniel Hogan's seminal article, this paper aims to contribute to the development of methodologies for integrating socio-demographic and environmental data in analyses of situations of socio-environmental vulnerability at the intra-urban scale. This approach should be an important part of the research agenda of the Working Group on Population, Space and Environment, of the Brazilian Association of Population Studies (Abep).
- ItemAcesso aberto (Open Access)Dinâmicas de urbanização na hiperperiferia da metrópole de São Paulo: análise dos processos de expansão urbana e das situações de vulnerabilidade socioambiental em escala intraurbana(Associação Brasileira de Estudos Populacionais, 2010-06-01) Alves, Humberto Prates da Fonseca [UNIFESP]; Alves, Claudia Durand; Pereira, Madalena Niero; Monteiro, Antonio Miguel Vieira; Universidade Federal de São Paulo (UNIFESP); Instituto Nacional de Pesquisas Espaciais Divisão de Sensoriamento Remoto; Universidade de São Paulo (USP)The objective of this article is to analyze, on an intraurban scale, the interrelations among processes of urban expansion and situations of socioenvironmental vulnerability in a hyperperipheral region of the São Paulo Metropolitan Region in recent years (2000 to 2006). This geographical region includes the district of Cidade Tiradentes and its surrounding area, located at the extreme eastern side of the municipality of São Paulo. The overall methodology of the study involves the mapping of the use of the soil and of the areas of urban expansion, using satellite images, as well as the identification and characterization of situations (areas) of socioenvironmental vulnerability. To this end, socioenvironmental indicators are constructed and analyzed based on census sectors from the Federal Census of 2000, including socioeconomic, demographic and environmental data. The results show a strong correlation between the processes of urban expansion and growth of substandard settlements and situations of socioenvironmental vulnerability in the hyperperipheral region of Cidade Tiradentes and its surrounding area. It was also seen that there are broad overlappings between social and environmental vulnerabilities, with strong concentration of social and environmental problems and risks in certain areas, as is the case of the census sectors of high socioenvironmental vulnerability in the Cidade Tiradentes region. These areas show irregularity in the use of the soil and widespread presence of substandard settlements such as shantytowns and irregular subdivision projects. There are also extremely critical socioeconomic conditions, with very low levels of income, formal education and sanitation.
