Abstract: This study examines the environmental impacts of drought in Andalusia (Spain) at a municipal scale, using satellite data from Google Earth Engine for the period 2004-2022. Key environmental variables analyzed include vegetation condition indices, primary productivity, terrestrial and groundwater levels and soil moisture. The research highlights the significant, yet often indirect, effects of drought on the environment and ecosystem services, particularly vegetation and water resources. Ground-truthing with official statistical data strengthens the reliability of the findings. The study reveals strong correlations between drought events and environmental variables, particularly during short-term droughts, demonstrating the significant influence of seasonal drought on vegetation, especially in grasslands and meadows. The results underscore the urgent need for enhanced climate change adaptation strategies and the development of greater resilience in ecosystems and local communities to address the increasing frequency and severity of droughts in the region.
