Resumo: The land use and occupation in watersheds directly influences the water resources, and the vegetation cover is a crucial factor for water maintenance. The objective of this study was to characterize the land use and occupation in nine watersheds of the Lower Iguaçu River (Andrada, Monteiro, Gonçalves Dias, Floriano, Silva Jardim, Cotejipe, Sarandi, Capanema and Santo Antônio sub-basin rivers), using the classification from satellite images. The classification area obtained high accuracy (Kappa coefficient of 99.4 to 99.9%). The Floriano River sub-basin presented the highest degree of environmental preservation, followed by Silva Jardim and Gonçalves Dias River sub-basins, fully or partially inserted in Iguaçu National Park. Monteiro and Sarandi river sub-basins showed the smallest areas of vegetation, and Capanema, Cotejipe, Andrada and Santo Antônio River sub-basins exhibited an intermediate condition. This tendency was verified by the cluster analysis. These results can serve as a baseline for planning, monitoring and management of this area, environmental modeling, conservation of water resources, biodiversity, and environmental services.

El objetivo de este estudio fue caracterizar el uso y la ocupación del suelo en nueve cuencas del bajo Iguaçú (ríos Andrada, Monteiro, Gonçalves Dias, Floriano, Silva Jardim, Cotejipe, Sarandi, Capanema y Santo Antônio), utilizando la clasificación de uso y ocupación de la tierra a partir de imágenes de satélite. La clasificación de áreas obtuvo una buena precisión (coeficiente Kappa de 99,4 a 99,9%) y la cuenca del Floriano fue la que presentó el mayor grado de preservación ambiental, seguida por las cuencas de los ríos Silva Jardim y Gonçalves Dias, insertas total o parcialmente en el Parque Nacional de Iguaçú. Las cuencas de los ríos Monteiro y Sarandi poseen las menores áreas de vegetación y los ríos Capanema, Cotejipe, Andrada y Santo Antônio se encuentran en una condición intermedia. La misma tendencia se verificó mediante el análisis de conglomerados.  Los resultados pueden servir de base para la planificación, el seguimiento y la gestión de la zona, la elaboración de modelos ambientales, la conservación de los recursos hídricos, la biodiversidad y los servicios ambientales.O uso e ocupação da terra em bacias hidrográficas influencia diretamente os recursos hídricos, sendo a cobertura vegetal um fator determinante para a conservação dos rios. O objetivo deste estudo foi caracterizar o uso e ocupação do solo em nove bacias do baixo rio Iguaçu (rios Andrada, Monteiro, Gonçalves Dias, Floriano, Silva Jardim, Cotejipe, Sarandi, Capanema e Santo Antônio), utilizando a classificação do uso e ocupação da terra a partir de imagens de satélite. A classificação da área obteve boa acurácia (coeficiente Kappa de 99,4 a 99,9%) e a bacia do Floriano foi a que apresentou o maior grau de preservação ambiental, seguida pelas bacias dos rios Silva Jardim e Gonçalves Dias, integral ou parcialmente inseridas no Parque Nacional do Iguaçu. As bacias dos rios Monteiro e Sarandi possuem as menores áreas da classe vegetação e os rios Capanema, Cotejipe, Andrada e Santo Antônio, encontram-se em uma condição intermediária. A mesma tendência foi verificada pela análise de agrupamento.  Os resultados podem servir de linha de base para o planejamento, monitoramento e manejo da área, modelagem ambiental, conservação dos recursos hídricos, da biodiversidade e dos serviços ambientais.Research, Society and Development2022-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3486810.33448/rsd-v11i13.34868Research, Society and Development; Vol. 11 No. 13; e66111334868Research, Society and Development; Vol. 11 Núm. 13; e66111334868Research, Society and Development; v. 11 n. 13; e661113348682525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/34868/29479Copyright (c) 2022 Jhony F.
