Avaliação da vulnerabilidade socioambiental dos distritos do município de São Paulo ao processo de escorregamento.

Abstract

With so many crises and disasters in recent years, related to extreme precipitation events, which often result in serious damage and, especially, loss of human lives, the discussion on social and environmental risks gains another dimension. The current model of development is characterized by the risk trivialization, considering that the incessant production of wealth is linked to the production of an increasing number of vulnerable contexts, especially in areas of great poverty-where the response to different impacts is greatly reduced. In the urban environment, the problem is further evidenced by the large extent of areas occupied by slums. The microclimatic changes observed in the large cities, as well as the scenarios presented by the Intergovernmental Panel on Climate Change, indicate the need for developing measures for the proper management of risks related to extreme events, since these may become more frequent and intense in the coming decades. This study seeks to accomplish a multidimensional analysis of the vulnerability of São Paulo city against processes related to heavy rainfall, particularly the landslides. Intends to point in space paulistano the close relationship between social and infrastructural vulnerability, and the area"s most susceptible to this type of phenomenon, a situation that characterizes urban segregation. To do this, makes use of social and environmental indicators. Based on secondary data, obtained from the IBGE and the Municipality of Sao Paulo, was developed a set of synthetic indices. They were integrated and included in a Geographic Information System, in order to point out different levels of socioenvironmental vulnerability among districts facing the process of landslide.

Vulnerability and Climate Change Perceptions: A Case Study in Brazilian Biomes

“…Thus, a situation of deprivation, which generally speaking characterizes poorer populations, fragile infra-structure, and precarious public services are some contributing factors. Brazilian studies that analyze vulnerability in urban areas describe these variables as socio-economic and socio-demographic factors Alves et al, 2010;Gamba, 2010).…”

Proposal of a Socio-Environmental Vulnerability Scale of Municipalities That Receive Financial Compensation – Brazil

“…In detail, socioeconomic indicators covered characteristics related to education, health, poverty, and socio-environmental conflicts. Such aspects are pointed out by the literature as necessary when assessing socio-environmental vulnerability, the indicators being selected according to their importance in the area, data availability, and methodological suitability to the Rasch model used (Philip & Rayhan, 2004;Gamba, 2010;Fernandes, 2007;Fernandes, 2016;Alijanzadeh, Asefzadeh & Zare, 2016;Unicef, 2020, Fiocruz, 2015Cannon, Twigg & Rowell, 2003;Almeida, 2010;Brooks, 2003;Freitas et al, 2012).…”

Vulnerabilidade Social E Infraestrutural Na Área Urbana De Campina Grande, Paraíba, Brasil

“…According to Gamba (2011), the concept of risk has a close relationship with that of vulnerability. Starting from the 1980s, the concept of vulnerability was incorporated into studies on Natural Hazard, however, it was only in the 1990s that this concept began to be disseminated and nowadays it is used in several areas of knowledge (MACEDO et al, 2015), covering, according to Anazawa et al (2011), a multiplicity of approaches.…”
