A multifaceted quantitative index for sustainability assessment of groundwater management: application for aquifers around Iran

This study developed a groundwater sustainable management index including components of environmental, social, economic and institutional responsibility. Four significant indicators: integrated groundwater footprint, population density, percentage of groundwater used for agricultural and industrial sectors, and density of observation wells were adopted and executed for 443 of Iran’s aquifers. The results indicated that the groundwater sustainable management for 32% of Iran’s aquifers is poor–very poor, and this index is more sensitive to economic and social indicators. Finally, an inverse correlation was observed between the groundwater sustainable management index values and the coefficient of variation of normalized difference vegetation index (R ² = −0.437).
