Resumo: | The mangrove is a transitional ecosystem between terrestrial and marine environments and represents an important ecological indicator for the ecosystem services provided. However, despite its ecological relevance, it still suffers anthropic pressures and has been losing in extent and environmental quality. In Brazil, and specifically in the municipality of Paranaguá, a mix of anthropogenic use has caused significant pressures on mangroves. In this sense, the aim of this study is to assess the degree of anthropization of the urban mangroves in the city of Paranaguá (PR), through the use of very high spatial resolution images, obtained from Remotely Piloted Aircraft in order to support municipal policies for land-use planning. From the methodological point of view, from field campaigns, maps were produced with the aid of QGIS 3.10 software, from the photointerpretation of orthomosaics. The legend of the anthropization classes covered: deposition of household waste (i), rubble (ii), discharge of untreated domestic effluents (iii) and manholes (iv). The results indicated a total of 475 points of anthropic pressure on the 22 mangrove patches analysed. The most prominent class was household waste, followed respectively by untreated domestic effluent discharge, debris (construction material) and, finally, shackle. In conclusion, the use of high-resolution orthomosaics proved to be an important and effective tool in the analysis of anthropization of urban mangroves, thus highlighting the areas with greater pressure and contributing to a continuous monitoring. The products of this research can help in the elaboration of land-use planning instruments for the municipality, highlighting the need for the construction of a holistic view in favor of mangrove conservation. |

No entanto, apesar da relevância ecológica, ainda sofre pressões antrópicas e vem perdendo em extensão e qualidade ambiental. No Brasil e, especificamente, no município de Paranaguá, uma mescla de uso antrópico tem causado pressões significativas sobre os manguezais. Neste sentido, o objetivo deste estudo é avaliar o grau de antropização dos manguezais urbanos do município de Paranaguá (PR), através da utilização de imagens de altíssima resolução espacial, obtidas através de Aeronave Remotamente Pilotada a fim de subsidiar políticas municipais de ordenamento territorial. Do ponto de vista metodológico, a partir de campanhas de campo, foram produzidos mapas com auxílio do software QGIS 3.10, a partir da fotointerpretação de ortomosaicos . A legenda das classes de antropização abrangeu: deposição de lixo domiciliar (i), entulhos (ii), lançamento de efluentes domésticos sem tratamento (iii) e manilhas (iv). Os resultados apontaram um total de 475 pontos de pressão antrópica sobre as 22 manchas de manguezal analisadas. A classe de maior destaque foi a de lixo domiciliar, seguida respectivamente de lançamento de efluentes domésticos sem tratamento, entulhos (material de construção) e, por fim, manilha. Como conclusão, o uso de ortomosaicos de alta resolução mostrou ser uma ferramenta importante e eficaz na análise da antropização dos manguezais urbanos, destacando assim , as áreas com maior pressão e, contribuindo para um monitoramento contínuo. Os produtos desta pesquisa podem auxiliar na elaboração de de instrumentos de ordenamento territorial do município, destacando a necessidade da construção de um olhar holístico em prol da conservação dos manguezais.Universidade Federal de Uberlândia2023-04-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/6751510.14393/SN-v35-2023-67515Sociedade & Natureza; Vol. 35 No. 1 (2023): Sociedade & Natureza; v. 35 n. 1 (2023): 1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/67515/35986https://seer.ufu.br/index.php/sociedadenatureza/article/view/67515/35987Copyright (c) 2022 Sidney Vincent de Paul Vikou, Otacílio Lopes de Souza da Paz, Daiane Maria Pilatti, Eduardo Vedor de Paulahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessVikou, Sidney Vincent de Paulda Paz, Otacílio Lopes de SouzaPilatti, Daiane Mariade Paula, Eduardo Vedor2023-08-25T14:35:59Zoai:ojs.www.seer.ufu.br:article/67515Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2023-08-25T14:35:59Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
