High Rate of Yazd Land Subsidence Alarming

The average global land subsidence is two centimeters per year, but it is much higher in some parts of Iran, mainly due to the over-extraction of water from groundwater resources, especially in Yazd Province.
“The annual drop in the level of groundwater in Yazd is caused by both over-extraction and reduction in rainfall. Every year, when there is poor rainfall, more water is extracted and as a result, the groundwater level declines. In such years, the land subsides by 50 cm,” the managing director of Yazd Regional Water Company said.
