Resumo: | Through almost five centuries of occupation and the resulting processes of landscape transformation, ecological scenarios in the neighborhood of Guaratiba have become areas of production, residence, and urban transition. This historicity is a key element to understand local vulnerabilities and associated risks. Thus, within the scope of landscape management and under an integrative approach of vulnerabilities and risks, our objective in this study is to map and analyze socio-ecological vulnerabilities and risks in the study area. Research was structured on i) investigating the history of landscape use, occupation and transformation, ii) identifying vulnerable areas, and iii) classifying socio-ecological risks. Three methodological steps were used: (1) analysis of historical processes of land use and occupation in Guaratiba; (2) delimitation of Socio-ecological Landscape Units (SELU) in order to understand current levels of heterogeneity in the study area; and (3) modeling and characterization of identified socio-ecological risks. Based on the geoprocessing technique known as fuzzy logic, analysis led to a socio-ecological classification of risks, recognizing that such phenomena can only be understood by examining human presence in face of the relevance of events which can harm exposed groups. The investigation showed that four out of six delimitated landscape units have points on which there is a tendency of risks: SELU 2, SELU 4, SELU 5, and SELU 6. These areas suggest socio-ecological risks of the physical type, related to geomorphologic (landslides and floods) and environmental health dynamics. |

Essa historicidade constitui elemento-chave para a compreensão das vulnerabilidades locais e riscos associados. Nesse sentido, no âmbito da gestão da paisagem, sob uma abordagem integradora de vulnerabilidade e riscos, temos como objetivo mapear e analisar as vulnerabilidades e riscos socioecológicos na área de estudo. O trabalho se estruturou na investigação da história de uso, ocupação e transformação da paisagem, na identificação de áreas vulneráveis, bem como na classificação dos riscos socioecológicos. Assim, estabeleceram-se três etapas metodológicas para tal compreensão: (1) análise dos processos históricos de uso e ocupação das terras em Guaratiba; (2) delimitação das Unidades Socioecológicas da Paisagem (USEP), com o intuito de compreender os níveis atuais de heterogeneidade da área estudada; e por fim, (3) a modelagem e categorização dos riscos socioecológicos identificados. Essa análise, baseada na técnica de geoprocessamento conhecida como lógica fuzzy, levou ao entendimento de uma classificação socioecológica dos riscos, reconhecendo que tais fenômenos só podem ser compreendidos a partir da presença humana perante a pertinência de eventos que possam ferir os grupos expostos. Como resultado desta investigação, quatro das seis unidades de paisagem delimitadas apresentaram locais com tendência a riscos: USEP 2, USEP 4, USEP 5 e USEP 6. Tais áreas sugerem riscos socioecológicos do tipo físico relacionados a dinâmicas geomorfológicas (deslizamentos e de enchentes) e de saúde ambiental.Universidade Federal de Uberlândia2021-05-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/5884110.14393/SN-v33-2021-58841Sociedade & Natureza; Vol. 33 (2021)Sociedade & Natureza; v. 33 (2021)1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/58841/31655https://seer.ufu.br/index.php/sociedadenatureza/article/view/58841/31656Copyright (c) 2021 Maria Luciene da Silva Lima, Alexandro Solórzano, Luiz Felipe Guanaes Rego, Marcelo Motta de Freitas, Bianca Pereira Alvim Portoinfo:eu-repo/semantics/openAccessLima, Maria Luciene da Silva Solórzano, Alexandro Rego, Luiz Felipe GuanaesFreitas, Marcelo Motta de Porto, Bianca Pereira Alvim2021-07-28T18:28:11Zoai:ojs.www.seer.ufu.br:article/58841Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-07-28T18:28:11Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
