The study identified that the origin of the erosion is associated with the concentration of stormwater runoff from the road system (Ayrton Senna Ring Road and BR- 050 highway), which altered the natural water flow and directed large volumes to a single point within the property. Based on satellite imagery, drone surveys, and field analyses, it was possible to monitor the evolution of the gully from 2016 to 2025, revealing continuous expansion. The study proposes the implementation of a Degraded Area Recovery Project (PRAD), using techniques such as the construction of bamboo check dams, seeding of grasses and legumes, installation of contour lines, and maintenance of existing drainage structures. It is concluded that the recovery of the area requires integrated interventions both at the erosion site and upstream, aiming to restore soil stability, vegetation cover, and the hydrological functionality of the landscape.

The use of satellite images and vegetation indices has proven effective in the analysis and assessment of vegetation cover in watersheds, especially in understanding biomass and its implications for climate change mitigation. The objective of this study is to analyze changes in land use and occupation in the Ribeirão Bom Jardim basin, using the Normalized Difference Vegetation Index (NDVI), the Photochemical Reflectance Index rescaled for positive values (sPRI), and Carbon Dioxide Flux (CO2 FLUX), allowing for an understanding of forest density patterns, atmospheric carbon sequestration capacity, and the photosynthetic efficiency of the region. Firstly, the study area was delineated, enabling the examination of its key characteristics such as topography, climate, soil type, and vegetation. Subsequently, using GIS (Geographic Information System), land use and deforestation analysis was conducted using Landsat 7 and 5 images. Finally, NDVI, sPRI, and CO2 FLUX indices were calculated. The results demonstrate a significant suppression of native cerrado vegetation between 2002 and 2008, leading to a decrease in carbon sequestration and photosynthetic efficiency. These findings underscore the importance of native cerrado vegetation not only as valuable ecosystems but also as significant contributors to climate change mitigation.

Without proper treatment, it can cause various diseases, especially diarrhea. One of the main indicators of water quality is the presence of coliform bacteria, which determine the presence of fecal contamination and waterborne pathogens. In universities, determining water potability is essential to assess potential health risks for the academic community. In this context, this study evaluated water samples from drinking fountains in the libraries of the UFU campuses with the highest concentration and flow of people: Glória, Santa Mônica, and Umuarama (blocks 1C, 3C, and 4G), verifying microbiological and physicochemical parameters and comparing them to the reference values of Ordinance No. 888/2021 of the Ministry of Health. Water samples were aseptically collected from all library drinking fountains, classified as 1C, 4G-E, 4G-T, 4G-P1 (these four in the first six weeks), 3C-E, 3C-T, 3C-P1, and 3C-P2 (these in the last six weeks), according to their location on each campus. Microbiological analysis was performed using the Standard Multiple Tube Method to obtain the Most Probable Number of bacteria. Gram staining was also used to further characterize bacteria. pH was measured using the potentiometric method. Electrical conductivity and total dissolved solids were measured using a multiparameter. Turbidity was measured using a turbidimeter. Free chlorine concentration was assessed using the colorimetric method. No total or thermotolerant coliforms were detected in any of the samples analyzed. Likewise, the physicochemical parameters also complied with the legislation. However, the chlorine concentration was below the minimum limit in several samples, particularly those from block 3C. These low concentrations may be due to natural decay due to distance from the chlorination point, lack of maintenance, low consumption, or high temperatures, in the case of water fountain 3C-E, which is exposed to the sun. It is recommended that the frequency of water fountain filter cleaning be reviewed and that water fountain 3C-E be moved so that chlorine concentrations meet the maximum permitted value established by law. Overall, this study indicated that the water supplied to the university community meets potability standards.
