Climate change has caused significant transformations in the water conditions of the Chingaza reservoir and its relationship with climatic and environmental factors. This research focuses on the use of aerospace technologies, environmental monitoring through satellite remote sensing, and geospatial data analysis to examine patterns and trends. The study emphasizes the importance of theChingaza reservoir as a crucial water source for millions of people in the city of Bogotá, which is currently facing daily water rationing. The correlation between NDVI and temperature shows a determination coefficient (R²) of 0.2531, indicating that 25.31% of the variability in temperature can be explained by NDVI. This suggests a moderate positive correlation between NDVI and temperature, with a p-value of 0.0001, indicating very high statistical significance. Regarding the correlation between NDWI and temperature, an R² of 0.2150 was observed, also suggesting a moderate positive correlation, with a p-value of 0.0005. Predictions for the years 2026, 2036, and 2046 indicate a decreasing trend in vegetation and surface moisture, suggesting possible desertification and biodiversity loss. These results underline the urgent need to implement conservation measures to mitigate these negative effects and protect the ecosystem in the region.
