Resumo: Purpose: The study aims to identify areas vulnerable to soil loss in the Potengi River hydrographic basin (BHRP) in Rio Grande do Norte, through a multicriteria analysis involving various geo-environmental attributes, in order to guide efforts towards efficient actions for the Recovery of Degraded Areas (RAD). Methodology: Data on geology, climate, geomorphology, pedology, hydrographic network, and interpretation of land cover and land use were collected. Through map algebra, it was possible to model the landscape of the basin and locate the areas most vulnerable to soil loss. Originality/Relevance: After the investigation using geoprocessing, the results generated in the form of cartographic products were evaluated and validated through field inspections to verify all situations identified as critical and assess the accuracy of the method used. It is important to note that in other studies conducted in BHRP, there was no specific objective of evaluating and validating the reality. Results: It was found that approximately 76% of the 4,170 km² area of the basin is moderately vulnerable to erosion, with nine critical areas of very high vulnerability identified, which need to reduce soil loss to avoid future effects such as drainage siltation and transport of soil nutrients. Social/Managerial contributions: Mapping the current state of land cover, land use, and preservation areas is essential to develop protection and monitoring measures. This allows for the implementation of initiatives such as Payment for Environmental Services (PSA) and the creation of a bank of priority areas, aiming to preserve water resources, especially in the semiarid region of Northeast Brazil.

Metodología: Se recopilaron datos de geología, clima, geomorfología, pedología, red hidrográfica e interpretación fotográfica de cobertura y uso de la tierra. Mediante álgebra de mapas, fue posible modelar el paisaje de la cuenca y localizar las áreas más vulnerables a la pérdida de suelo. Originalidad/Relevancia: Después de la investigación con geoprocesamiento, los resultados generados en forma de productos cartográficos fueron evaluados y validados mediante inspecciones de campo para verificar todas las situaciones señaladas como críticas y evaluar la precisión del método utilizado. Es importante destacar que, en otros trabajos realizados en BHRP, no se identificó un objetivo específico de evaluar y validar la realidad. Resultados: Se encontró que aproximadamente el 76% de la superficie de 4.170 km² de la cuenca es moderadamente vulnerable a la erosión, con nueve áreas críticas de alta vulnerabilidad identificadas, que necesitan reducir la pérdida de suelo para evitar futuros efectos, como el enarenamiento de los drenajes y el transporte de nutrientes del suelo. Contribuciones Sociales/Gerenciales: Mapear el estado actual de la cobertura y uso de la tierra y las áreas de preservación es esencial para desarrollar medidas de protección y vigilancia. Esto permite la implementación de iniciativas como el Pago por Servicios Ambientales (PSA) y la creación de un banco de áreas prioritarias, con el objetivo de preservar los recursos hídricos, especialmente en el semiárido del noreste de Brasil.Objetivo: O estudo visa identificar áreas vulneráveis à perda de solo na Bacia hidrográfica do Rio Potengi (BHRP) no Rio Grande do Norte, por meio de análise multicritério envolvendo vários atributos geoambientais, a fim de orientar esforços para ações eficientes de Recuperação de Áreas Degradadas (RAD). Metodologia: Foram levantados dados de geologia, do clima, da geomorfologia, pedologia, rede hidrográfica e foto interpretação da cobertura e uso da terra. Por meio da álgebra de mapas foi possível modelar a paisagem da bacia e localizar as áreas mais vulneráveis à perda de solo. Originalidade/Relevância: Após a investigação com geoprocessamento, os resultados gerados na forma de produtos cartográficos foram avaliados e validados por meio de vistorias de campo, a fim de verificar todas as situações apontadas como críticas e avaliar a precisão do método utilizado. É importante ressaltar que, em outros trabalhos realizados na BHRP, não foi identificado um objetivo específico de avaliar e validar a realidade. Resultados: Verificou-se que cerca de 76% da área de 4.170 km² da bacia encontra-se moderadamente vulnerável à erosão, sendo identificadas nove áreas críticas de vulnerabilidade muito alta, e que precisam reduzir a perda de solo para evitar efeitos futuros, como o assoreamento das drenagens e transporte de nutrientes do solo. Contribuições Sociais/Gerenciais: Mapear o estado atual da cobertura e uso da terra e das áreas de preservação é essencial para desenvolver medidas de proteção e fiscalização. Isso permite a implementação de iniciativas como o Pagamento por Serviços Ambientais (PSA) e a criação de um banco de áreas prioritárias, visando preservar os recursos hídricos, especialmente no semiárido do Nordeste brasileiro.Universidade Nove de Julho - Uninove2024-02-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://periodicos.uninove.br/geas/article/view/2424710.5585/2024.24247Revista de Gestão Ambiental e Sustentabilidade; v. 13 n. 1 (2024): Fluxo Contínuo; e242472316-9834reponame:Revista de Gestão Ambiental e Sustentabilidade - GeASinstname:Universidade Nove de Julho (UNINOVE)instacron:UNINOVEengporhttps://periodicos.uninove.br/geas/article/view/24247/10732https://periodicos.uninove.br/geas/article/view/24247/10733Copyright (c) 2024 Matheus Natan Ferreira Alves Sousa, Caio Victor Macêdo Pereira, Fellipe Souza Araujo, Ivo Cavalcanti Neto, Joyce Clara Vieira Ferreira, Paulo Eduardo Vieira Cunha, Carlos Wilmer Costahttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessSousa, Matheus Natan Ferreira AlvesPereira, Caio Victor MacêdoAraujo, Fellipe SouzaNeto, Ivo CavalcantiFerreira, Joyce Clara VieiraCunha, Paulo Eduardo VieiraCosta, Carlos Wilmer2024-03-21T13:19:54Zoai:ojs.periodicos.uninove.br:article/24247Revistahttps://periodicos.uninove.br/geasONGhttps://periodicos.uninove.br/geas/oai||journalgeas@gmail.com2316-98342316-9834opendoar:2024-03-21T13:19:54Revista de Gestão Ambiental e Sustentabilidade - GeAS - Universidade Nove de Julho (UNINOVE)false
