Resumo: Removing original vegetation, irregularly waste dispositioning, increasing impermeable area on slopes, along with high rainfall, cause accidents that generate property damage and risk to people. Thus, the present study aims to assess the risk degree for a slope located in Olinda, Pernambuco, Brazil. As for the methodology, there was a site visit to assess factors that enhance the landslides followed by a quantitative analysis of the occupation dynamics at the site, through Qgis software, from 1975 to 2018. Finally, a qualitative analysis was carried out through the matrix of probability/consequence for risk assessment. Over time, the percentage of urban areas increased by 122.95% while the percentage of vegetation decreased by 55.40%. It was concluded that the environmental impacts affect or interfere at a median level. The anthropic actions most likely to have an impact on the area were: land use and occupation, sewage released directly into the soil, and vegetation cover suppression.

Así, el presente estudio tiene como objetivo evaluar el grado de riesgo de un talud ubicado en el municipio de Olinda-PE. La metodología consistió en una visita al sitio para evaluar los factores que potencian los deslizamientos, seguido de un análisis cuantitativo de la dinámica de ocupación del sitio utilizando el software Qgis entre los años 1975 y 2018. Finalmente, se realizó un análisis cualitativo a través de la matriz. de probabilidad / consecuencia para la evaluación de riesgos en el sitio. Con el tiempo, el porcentaje de área referida a áreas urbanas aumentó en un 122,95% y el porcentaje de vegetación disminuyó en un 55,40%. Se evaluó que, para el área de estudio, los impactos ambientales analizados afectan o interfieren a nivel mediano. Las acciones antrópicas con mayor probabilidad de tener impacto en la zona fueron el uso y ocupación del suelo, las aguas residuales vertidas directamente al suelo y la supresión de la cubierta vegetal.A retirada da vegetação original, a deposição irregular de lixo e resíduo, o aumento da área impermeável em locais de encostas, atrelado aos altos índices pluviométricos, acabam por desencadear acidentes que geram danos materiais e à própria vida dos moradores. Dessa forma, o presente trabalho tem o objetivo de avaliar o grau de risco de uma encosta localizada no município de Olinda-PE. A metodologia consistiu em visita ao local para avaliação dos fatores que potencializam os deslizamentos, seguido de uma análise quantitativa da dinâmica de ocupação do local através do software Qgis entre os anos de 1975 e 2018. Por fim, foi realizado a análise qualitativa através da matriz de probabilidade/consequência para avaliação do risco no local. Com o passar do tempo, o percentual de área referente a mancha urbana aumentou 122,95% e o percentual de vegetação, reduziu 55,40%. Foi avaliado que, para a área de estudo, os impactos ambientais analisados afetam ou interferem em nível mediano. As ações antrópicas com maior probabilidade de gerar impactos na área foram o uso e a ocupação do solo, o esgoto lançado diretamente no solo e a supressão da cobertura vegetal.Research, Society and Development2020-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/981710.33448/rsd-v9i11.9817Research, Society and Development; Vol. 9 No. 11; e3499119817Research, Society and Development; Vol. 9 Núm. 11; e3499119817Research, Society and Development; v. 9 n. 11; e34991198172525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/9817/10535Copyright (c) 2020 Aléssia de Albuquerque Pedrosa; Suyanne Monteiro de Almeida; Kalinny Patrícia Vaz Lafayettehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPedrosa, Aléssia de Albuquerque Almeida, Suyanne Monteiro deLafayette, Kalinny Patrícia Vaz 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/9817Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:00.553246Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
