Metodologia para priorização de ações em aglomerados subnormais considerando os riscos de deslizamentos e inundações e as condições de moradia

Abstract

The problems regarding disaster risk areas in Brazilian cities, mainly hydrometeorological ones, such as flooding, as well as geological, like landslides, are typically related to socioeconomic and environmental determinants. Therefore, the search for methodologies aiming at understanding the vicissitudes of the dynamics in urban environment is essential in order to develop actions that may minimize these issues. This article proposed a novel integrated multiobjective methodology with the purpose of prioritizing actions for housing improvements or relocation of slums settlements in risk-prone areas. In addition, a brief analysis of three areas in the city of João Pessoa, state of Paraíba, Brazil, was presented. The results indicated that the best option is housing relocation for 4.5% of the total dwellings surveyed, and for 14.1% of them, housing improvement was proposed.
