The Mundaú River Basin has already faced several problems, such as droughts and floods, which have significantly impacted the societies that live in and depend on it. Considering the relevance of the basin, this study sought to investigate its socio-environmental susceptibility, analyzing the transformations in land cover and land use and understanding how these changes, together with extreme climatic events, intensified the socio-environmental impacts. The analyses were carried out in an integrated manner, aiming to broaden the understanding of the influence of extreme climatic phenomena, land use and cover, and the risks of susceptibility present in the region. Data from institutions such as the National Institute for Space Research (INPE), the National Institute of Meteorology (INMET), the National Water Agency (ANA), the Pernambuco Water and Climate Agency (APAC), the Brazilian Institute of Geography and Statistics (IBGE), and the Secretariat of Environment and Water Resources (SEMARH) were used. Transformations in land use and cover were identified through geoprocessing and remote sensing techniques, based on satellite images and thematic maps. Extreme climatic events were characterized through historical rainfall series and specific indices calculated with the help of the RClimdex software. The mapping of socioenvironmental susceptibility was carried out by combining physical, social, and climatic parameters, allowing the identification of areas more susceptible to floods, droughts, and environmental degradation. Based on the analyses carried out, it was possible to identify the main impacts associated with changes in land use and hydrometeorological events, as well as to evaluate the mitigation or adaptation measures adopted, where they exist, by local public authorities. At the end of the research, a more in-depth view of the environmental dynamics of the Mundaú River Basin was obtained, as well as technical information that can guide public policies aimed at the sustainable management of natural resources. As a technicaleducational product, an illustrated and interactive didactic material was developed for high school students, covering content on cartography, land use, extreme weather events, and environmental sustainability. It is expected that this material will contribute to the critical thinking of young people and to the strengthening of environmental education in the territories that make up the basin.ptGerenciamento de bacias hidrográficasRio MundaúEnchentesVariação climáticaCobertura de terraLand CoverWatershed ManagementMundaú RiverFloodsClimate VariabilityDissertaçãoOUTROS
