This study aims to assess the impact of climate change on vegetation and water resources in the Safsaf watershed of northeastern Algeria. We analyzed Landsat satellite imagery from 2012 to 2022 to compute the Normalized Difference Vegetation Index (NDVI) and employed MODIS and CHIRPS data through Google Earth Engine (GEE) to explore the relationships between NDVI, Land Surface Temperature (LST), and precipitation. Our analysis revealed a significant decline in water surfaces and vegetation cover, which correlates with increased human activities and rapid urbanization due to population growth. Pearson’s correlation analysis indicated a moderate negative relationship between NDVI and LST, alongside a weak negative correlation between the Normalized Difference Water Index (NDWI) and precipitation. These findings highlight the urgent need for integrated environmental management strategies to mitigate climate change impacts and prevent further degradation of the Safsaf watershed, emphasizing the importance of incorporating ecological and hydrological considerations into future planning efforts.
