RESUMO:

 

The degradation of water resources, especially springs, has intensified due to urban expansion, agriculture, and unsustainable land use models, compromising the quantity and quality of available water. In the municipality of Sinop/MT, located in the Upper Teles Pires basin, the Ribeirão Preto river basin has been suffering strong anthropogenic pressure, marked by the replacement of forest cover with agriculture and urban densification. In this context, the present study aimed to assess the conservation status of the springs in the Ribeirão Preto river basin, through the identification and mapping of springs, the combined application of the Spring Environmental Impact Index (IIAN) and an adapted Rapid Assessment Protocol (PAR), as well as the development of cartographic products and educational material aimed at environmental education. This is a case study, developed between 2023 and 2025, organized in three stages: (i) a literature review, articulated as a state-of-the-art study in CAPES and SciELO databases, focusing on the restoration, regeneration, and degradation of springs; (ii) field surveys and drone image recording of 12 springs, georeferenced with GPS, with macroscopic evaluation of physical, anthropogenic, and legal protection parameters; and (iii) the creation of thematic maps and educational material for children entitled "The Adventures of Mika and Rafa," focusing on environmental awareness. The application of the IIAN (Integrated Environmental Assessment Index) indicated a polarized scenario: four springs in "Excellent" condition, one in "Good" condition, and four in "Very Poor" condition, associating the best performances with the presence of continuous riparian forest, absence of sewage, low presence of waste, and effective protection of the Permanent Preservation Area (APP). Conversely, the most degraded springs are linked to urban and rural areas, with fragmented or absent vegetation, artificial dams, rainwater drainage directed towards the spring, and a riparian buffer zone (APP) smaller than the minimum radius of 50 m stipulated in the Forest Code. The adapted PAR (Riparian Conservation Assessment) method, applied with drone imagery support, confirmed the observed pattern: springs with wider riparian zones, stable surroundings, and isolated APPs were classified as Excellent or Good, while those with degraded surroundings, drained wetlands, and lack of protection were classified as Poor or Very Poor. The generated maps highlighted the direct relationship between land use and occupation and the degree of conservation of the springs, providing support for municipal management and Basin Committees. The educational material produced reinforces the educational component of the research, contributing to the formation of a culture of preservation aimed at future generations and aligned with SDGs 4, 6, 13, and 15.
