Ecological issues

Towns and villages around Isfahan have been hit so hard by drought and water diversion that they have emptied out and people who lived there have moved. An anonymous journalist said that what's called drought is more often the mismanagement of water. The subsidence rate is dire, and the aquifer level decreases by one meter annually. As of 2020, the city had the worst air quality between major Iranian cities.
