Resumo: Studying a watershed in the Amazon region requires understanding that this region has national and global relevance. The fact that the study area is located in the so-called arc of deforestation raises the need to understand its context, its vulnerabilities, and its physical, environmental, and anthropic components. This research assesses the environmental vulnerability of the Buriticupu River Watershed in Maranhão State, Brazil. The aim is to foster improvements that may contribute to environmental planning and, specifically, to water resource management. For this purpose, the authors used the Geographic Information System environment to work with Map Algebra, interrelating primary and secondary data on geology, relief, pedology, and land use and land cover to generate synthesis cartography. The results pointed to areas with predominantly medium vulnerability. However, the analyses highlight alluvial plains, which became the most fragile areas from an environmental point of view. This is mainly because these areas comprise water-saturated soils (gleysols), unconsolidated deposits of sand and silt (alluvial deposits), and extensive humid vegetation, characteristics of igapó and floodplain forests. This research generated a document that applies is applicable to the study area. It also provided, in a systemic and integrated way, a product that will help in planning, which is very important for the creation of a watershed committee, something necessary and still embryonic in Maranhão State, Brazil.

Esta investigación tuvo como objetivo evaluar la vulnerabilidad ambiental de la cuenca del río Buriticupu/Maranhão con el fin de promover mejoras que puedan contribuir al proceso de planificación ambiental y, específicamente, de los recursos hídricos. Para ello, se utilizó el entorno del Sistema de Información Geográfica para trabajar con el Álgebra de Mapas, interrelacionando los datos primarios y secundarios sobre geología, relieve, edafología y uso y cobertura del suelo, para generar una cartografía de síntesis. Los resultados indicaron áreas con predominio de clases de vulnerabilidad media, sin embargo, el destaque es para las planicies aluviales, que se convirtieron, en los análisis, en las áreas más frágiles desde el punto de vista ambiental, especialmente por ser suelos saturados de agua (gleissolos), depósitos no consolidados de arena y limo (depósitos aluviales) y por exhibir una extensa vegetación húmeda, característica de los bosques de igapó y de las planicies aluviales. Este estudio pudo generar un documento aplicable al área de estudio, además de proporcionar, de forma sistémica e integrada, un producto que contribuirá a una posible planificación, especialmente para un futuro comité de cuenca hidrográfica, algo necesario y aún embrionario en Maranhão.Pesquisar uma bacia hidrográfica na região Amazônica requer assimilar que esta apresenta uma relevância nacional e mundial, estando a área de estudo situada no chamado arco do desmatamento, eleva a necessidade de entender seu contexto, vulnerabilidades e componentes físicos, ambientais e antrópicos. Esta pesquisa objetivou avaliar a vulnerabilidade ambiental da Bacia Hidrográfica do rio Buriticupu/Maranhão, com vistas a fomentar melhorias que possam contribuir com o processo de planejamento ambiental e, especificamente, de recursos hídricos. Para tanto, utilizou-se o ambiente de Sistema de Informação Geográfica para trabalhar com a Álgebra de Mapas, interrelacionando dados primários e secundários sobre a geologia, relevo, pedologia e uso e cobertura da terra, para gerar uma cartografia de síntese. Os resultados apontaram áreas com predominância das classes médias de vulnerabilidade, entretanto, o destaque fica por conta das planícies aluviais, que se tornaram, nas análises, as áreas mais frágeis do ponto de vista ambiental, sobretudo por serem solos saturados em água (gleissolos), depósitos inconsolidados de areia e silte (depósitos aluvionares) e por exibirem extensas vegetações úmidas, características de matas de igapó e de várzea. Este estudo foi capaz de gerar um documento que seja aplicável à área de estudo, além de propiciar, de modo sistêmico e integrado, um produto que contribuirá para possíveis planejamentos, sobretudo para um futuro comitê de bacia hidrográfica, algo necessário e ainda embrionário do Maranhão.Universidade Federal de Uberlândia2023-01-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/6667910.14393/SN-v35-2023-66679Sociedade & 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/66679/35486https://seer.ufu.br/index.php/sociedadenatureza/article/view/66679/35487Copyright (c) 2022 Rafael Brugnolli Medeiros, Luiz Carlos Santos, José Fernando Rodrigues Bezerra, Quesia Duarte Silva, Silas Nogueira Melohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMedeiros, Rafael BrugnolliSantos, Luiz CarlosBezerra, José Fernando RodriguesSilva, Quesia DuarteMelo, Silas Nogueira2023-08-25T14:36:00Zoai:ojs.www.seer.ufu.br:article/66679Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2023-08-25T14:36Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false
