Analyzing Environmental Dynamics in the Center of Iran: Impacts of Climatic and Environmental Factors Using Remote Sensing and Spatial Analysis in Google Earth Engine and R Software

Introduction: Environmental changes driven by anthropogenic and natural factors significantly affect human health, the environment, and economic systems globally. This study investigated the ecological impacts of environmental variables in the Yazd-Ardakan Plain using remote sensing data and geospatial analysis. Materials and Methods: Google Earth Engine (GEE) and R software were used to assess spatiotemporal trends from ۲۰۱۸ to ۲۰۲۳ using data from Landsat-۸, Sentinel-۲, and Sentinel-۵P. Key indices, including the Normalized Difference Vegetation Index (NDVI), temperature, surface runoff, and concentrations of NO۲, CO, O۳, and SO۲, were calculated to evaluate patterns in green space, air quality, temperature, and precipitation. Results: Elevated NO۲ and CO levels were observed in the centers of Yazd and  Ardakan, with O۳ and SO۲ peaking in ۲۰۱۹-۲۰۲۰ and improving by ۲۰۲۳. The highest aerosol concentrations were in ۲۰۱۹ and ۲۰۲۳, with a decrease in ۲۰۲۲. NDVI values peaked in ۲۰۲۰ but declined until ۲۰۲۳. The spatial analysis identified denser green spaces in Ardakan, elevated temperatures in Steel, and consistent precipitation across the regions. A positive correlation was found between temperature and pollution, whereas NDVI and precipitation showed negative correlations with temperature, indicating that vegetation loss exacerbates the effects of warming and pollution. Conclusion: This study highlights significant climatic and environmental changes in the Yazd-Ardakan plain from ۲۰۱۸ to ۲۰۲۳, including rising temperatures and pollution, alongside declining precipitation and vegetation. These trends underscore the need for targeted management strategies to mitigate environmental degradation, protect public health, and promote sustainable development through advanced monitoring and policy intervention.
