Overview

This analysis reveals severe land surface subsidence in Iran, with aquifer depletion indicating significant risk for urban populations.

Key Points

  • Iran is experiencing an extensive aquifer depletion, with documented land surface subsidence over 31,400 km² impacting groundwater resources.
  • Maximum subsidence rates reached 340 mm/yr in Rafsanjan, with 77% of subsidence faster than 10 mm/yr linked to agricultural activities.
  • Independent Component Analysis highlighted that 60% of the observed subsidence is irreversible, indicating a severe hydrological issue.
  • Recent drought conditions from 2020 to 2023 further escalated the risks associated with differential subsidence gradients, affecting 650,200 residents.
