Dynamics of the agricultural frontier of the zapotal hydrographic basin system through remote sensing tools
Deforestation is one of the most critical problems facing humanity. Ecuador is one of the Latin American countries with the highest rate of forest clearing compared to its size, mainly due to the increase in agricultural area. The objective of this work was to determine the dynamics and changes that...

| description | Deforestation is one of the most critical problems facing humanity. Ecuador is one of the Latin American countries with the highest rate of forest clearing compared to its size, mainly due to the increase in agricultural area. The objective of this work was to determine the dynamics and changes that have occurred in the agricultural frontier in the last 30 years in the hydrographic basins belonging to the Zapotal using remote sensing tools. The images were obtained from the Sentinel 2 and Landsat satellites from 1990 to 2020. The free QGIS software was used to analyze, classify and process the satellite images; Through a confusion matrix and the kappa index, precision was evaluated. High quality and resolution satellite images corresponding to the period from 1990 to 2020 were obtained and processed. The Normalized Difference Vegetation Index (NDVI) allowed us to know the dynamics of the formation of the vegetation of the studied period and, consequently, the uses of the land. soil depending on the vegetation cover. The dynamics of the agricultural frontier, determined through the remote sensing tools used in this study, shows a decrease of approximately 15%. The methodology used in this study proved to be effective and economical to understand the dynamics of the agricultural frontier, which provides an effective tool to monitor, plan, and execute various territorial planning and local development projects. |

Ecuador es uno de los países latinoamericanos con mayor tasa de tala de bosques en comparación con su tamaño, debido principalmente al aumento de la superficie agrícola. Este trabajo tuvo como objetivo determinar la dinámica y cambios ocurridos en la frontera agrícola en los últimos 30 años en las cuencas hidrográficas pertenecientes al Zapotal utilizando herramientas de teledetección. Las imágenes fueron obtenidas de los satélites Sentinel 2 y Landsat desde 1990 hasta 2020. Se utilizó el software libre QGIS para analizar, clasificar y procesar las imágenes satelitales; a través de una matriz de confusión y el índice de kappa se evaluó la precisión. Se obtuvieron y procesaron imágenes satelitales de alta calidad y resolución correspondientes al periodo de 1990 a 2020. El Índice de Vegetación de Diferencia Normalizada (NDVI) permitió conocer la dinámica de la conformación de la vegetación del período estudiado y, en consecuencia, los usos del suelo en función de la cobertura vegetal. La dinámica de la frontera agrícola, determinada mediante las herramientas de teledetección utilizadas en este estudio, evidencia una disminución de aproximadamente un 15%. La metodología utilizada en este estudio demostró ser efectiva y económica para conocer la dinámica de la frontera agrícola, lo que proporciona una herramienta eficaz para monitorear, planificar y ejecutar diversos proyectos de ordenamiento territorial y desarrollo local.O desmatamento é um dos problemas mais críticos que a humanidade enfrenta. O Equador é um dos países latino-americanos com maior taxa de desmatamento em relação ao seu tamanho, principalmente devido ao aumento da área agrícola. Este trabalho teve como objetivo determinar a dinâmica e as mudanças na fronteira agrícola nos últimos 30 anos nas bacias hidrográficas de Zapotal usando ferramentas de sensoriamento remoto. As imagens foram obtidas para os satélites Sentinel 2 e Landsat de 1990 a 2020. O software gratuito QGIS foi utilizado para analisar, classificar e processar as imagens de satélite, por meio de uma matriz de confusão, e o índice kappa avaliou a precisão. Foram obtidas e processadas imagens de satélite de alta qualidade e resolução correspondentes aos últimos 30 anos da área de estudo. O Índice de Vegetação por Diferença Normalizada (NDVI) permitiu conhecer a dinâmica da conformação da vegetação do período estudado e, consequentemente, os usos do solo com base na cobertura vegetal. O aumento da fronteira agrícola por meio das ferramentas de sensoriamento remoto utilizadas neste estudo foi de aproximadamente 23%. A metodologia utilizada neste estudo é eficaz e econômica para o conhecimento da dinâmica da fronteira agrícola, permitindo uma ferramenta eficaz para monitorar, planejar e executar diversos projetos de planejamento territorial e desenvolvimento local, entre outros.Universidad Técnica Estatal de Quevedo2023-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.uteq.edu.ec/index.php/cyt/article/view/63710.18779/cyt.v16i1.637Ciencia y Tecnología; Vol. 16 No. 1 (2023): Science and Technology Journal January - June 2023; 12-23Ciencia y Tecnología; Vol. 16 Núm. 1 (2023): Revista Ciencia y Tecnología Enero - Junio 2023; 12-23Ciencia y Tecnología; v. 16 n. 1 (2023): Revista Ciencia y Tecnología Enero - Junio 2023; 12-231390-40431390-405110.18779/cyt.v16i1reponame:Revista Ciencia y Tecnologíainstname:Universidad Técnica Estatal de Quevedoinstacron:UTEQspahttps://revistas.uteq.edu.ec/index.php/cyt/article/view/637/780https://revistas.uteq.edu.ec/index.php/cyt/article/view/637/781Derechos de autor 2023 Yoansy García, Danilo Valdez, Daniel Mancerohttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccess2025-04-11T17:03:35Zoai:revistas.uteq.edu.ec:article/637Portal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2025-04-11T17:03:35falsePortal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2025-04-11T17:03:35Revista Ciencia y Tecnología - Universidad Técnica Estatal de Quevedofalse |
