Abstract

A deeper understanding of environmental vulnerability is essential for crafting effective sustainability strategies. However, data deficiencies and methodological uncertainties often obscure a comprehensive grasp of the underlying issues. This study employs Google Earth Engine (GEE)-coded satellite imagery and the Getis spatial autocorrelation test to examine spatial patterns of environmental vulnerability in 397 Iranian counties from 2011 to 2021, framed within the theoretical lens of vulnerability.
The results of the Getis test reveal heterogeneous distributions and diverse vulnerability patterns across Iranian counties in various dimensions, including air pollution, greenhouse gas emissions, changes in temperature and precipitation, groundwater depletion, biodiversity threats, and soil erosion, particularly in the central, southern, eastern, and northern regions. Emphasizing the role of distinct spatial patterns in terms of "sensitivity" and "exposure," this research suggests that environmental policies in Iran should be tailored to regional spatial disparities and socio-ecological characteristics.
This approach can enhance adaptive capacity and mitigate environmental vulnerability in critical areas. The use of algorithmic techniques for environmental vulnerability indexing, combined with spatial data and population analysis, provides a robust framework for future research. This framework can be applied in national and regional planning to alleviate environmental pressures and improve sustainability.
