Resumo: | Erosion represents a crucial challenge for sustainable land use planning, especially with increasing agricultural activity and changes in production methods. This process leads to higher susceptibility to soil erosion, resulting in productivity losses and environmental degradation. Therefore, assessment methods are essential. This study compares the Universal Soil Loss Equation (USLE) with the Embrapa Erosion Susceptibility Map, utilizing geospatial data and applying it at different watershed planning scales. The objective is to assess and validate these methodologies, using satellite imagery to identify advanced erosive processes such as gullies. The results indicate that the Susceptibility Map showed better correspondence with gully areas, while the USLE had some discrepancies, possibly due to its higher spatial resolution. However, it emphasizes the importance of on-site verification through field visits to complement model analyses. |

Isso leva a uma maior suscetibilidade à erosão do solo, resultando em perdas de produtividade e degradação ambiental. Portanto, métodos de avaliação dos processos erosivos são fundamentais. Este estudo compara a Equação Universal de Perda de Solo (USLE) com o Mapa de Suscetibilidade à Erosão da Embrapa, ambos usando dados geoespaciais e aplicáveis em diferentes escalas de planejamento de bacias hidrográficas. O objetivo é avaliar e validar essas metodologias, usando imagens de satélite para identificar processos erosivos avançados, como voçorocas. Os resultados indicam que o Mapa de Suscetibilidade apresentou melhor correspondência com áreas de voçorocas, enquanto a USLE teve algumas discrepâncias, possivelmente devido à sua resolução espacial mais alta. No entanto, enfatiza-se a importância de verificar as condições no local por meio de visitas de campo para complementar as análises dos modelosInstituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte2023-12-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoapplication/pdfapplication/pdfhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/16380HOLOS; v. 3 n. 39 (2023): v.3(2023)1807-1600reponame:Holosinstname:Instituto Federal do Rio Grande do Norte (IFRN)instacron:IFRNporenghttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/16380/3850http://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/16380/3851Brasilhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSoares, Larissa Wainberg Bohrer, PedroAndrades Paixão, Mauricio de Almeida Silva, Maria Cristina2023-12-19T12:13:09Zoai:holos.ifrn.edu.br:article/16380Revistahttp://www2.ifrn.edu.br/ojs/index.php/HOLOSPUBhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/oaiholos@ifrn.edu.br||jyp.leite@ifrn.edu.br||propi@ifrn.edu.br1807-16001518-1634opendoar:2023-12-19T12:13:09Holos - Instituto Federal do Rio Grande do Norte (IFRN)false |
