Política de gerenciamento de risco nas encostas: estudo de caso Vila Sahy, litoral norte de São Paulo

Abstract

The vulnerability of Brazilian citizens to natural disasters is closely linked to the lack of adequate housing for the working classes and the lack of land-use planning that prioritizes the social interest over the private interest of landowners. The lack of access to housing and land regularization has led the lower classes to resort to self-building and occupying public or private land with lower market value, often in areas of risk, environmental preservation or protection of water sources, where the real estate market has no interest or viable action. This history of occupation has resulted in adverse impacts both from the action of nature on the built space and from the effects of space on nature, manifested in natural disasters, pollution of water sources and lack of green areas, which affect the entire population. Irregular occupation in precarious settlements in Brazil increases and amplifies environmental risk scenarios. In this context, it is up to the states and the federal government to support the implementation of public policies that link housing production, the provision of infrastructure and the execution of safety works on slopes and macrodrainage. Based on this data, the aim of this paper was to study the risk management policy and the mapping carried out by Civil Defense together with the Institute for Technological Research (IPT) in Vila Sahy, located in São Sebastião, on the north coast of São Paulo. A field survey was therefore carried out in the region to assess whether the population interviewed is aware of the risk management policy and whether they are aware of the government platforms that indicate these situations. It is hoped that this project can contribute to improving the work already carried out by Civil Defense to prevent possible tragedies in areas of vulnerability. After surveying the data, it is evident that in addition to analyzing the Civil Defense's method of action, it would also be necessary to structure the site with escape routes and lectures to raise awareness among the local population
