População urbana exposta aos riscos de deslizamentos, inundações e enxurradas no Brasil

Abstract: O conhecimento sobre a população urbana expostos ao risco de desastres é imprescindível para o planejamento de ações de prevenção e resposta. O objetivo do presente trabalho é analisar as condições de exposição de grupos populacionais  em áreas de risco de desastres em 479 municípios brasileiros. O procedimento metodológico baseou-se na associação de dados censitários e de áreas de risco de deslizamentos, enxurradas e inundações. A base de dados foi constituída de dados sociodemográficos e ambientais, que perm… Show more

“…The authors suggest that such knowledge is essential for decision-making in several strategic areas, especially the planning of activities aimed at mitigating the impacts associated with extreme hydrological events. Saito et al (2019) reported that, although hydrological processes are part of the natural dynamics of the earth's surface, a social system prepared to counter these events is more successful in reducing economic and social impacts, given the complexity in the relationships of the natural components involved in hydrographic basins (Aragão and Gomes, 2019). Miguez et al (2018) reported that the probability of occurrence of a dangerous event is one of the components of the modern concept of risk management having the expectation of losses caused by the event as the other component (this subdivided according to the danger and vulnerability, among other factors).…”

“…Pesquisa conduzida pelo Centro Nacional de Monitoramento e Alertas de Desastres Naturais (Cemaden, 2019) e publicada, também, em 2019, indica que a região Sudeste concentrou, no ano de 2018, a maior quantidade de áreas de risco de inundações e deslizamentos mapeadas do Brasil (Saito et al, 2019). Por apresentar as mais altas taxas de densidade demográfica do País, é de se supor que resultou em um maior número de pessoas afetadas por desastres naturais durante o perío do analisado.…”

“…The effects of ENSO phenomena vary according to the region of the continent, depending on the interaction between the Andes Mountains located on the coast of the Pacific Ocean [12,13] and climate systems acting on the continent, such as the Bolivian Alta (AB), which has a strong ability to make air rise that is directly related to the rainfall regime of the South American continent [14,15]; the Intertropical Convergence Zone (ITCZ), which is the area where the northern hemisphere trade winds converge with the southern hemisphere trade winds; and the Humidity Convergence Zone (ZCOU), where the humidity and upward movements of air converge, forming clouds, rains, storms, and hurricanes [16].…”
