Prolonged drought and the halt to permanent flows in the Zayandeh-Roud river have driven land subsidence and the Gavkhouni wetland toward an apparent point of no return, raising risks to Isfahan’s drinking-water supply, a provincial environmental official said.
“The continued drying and the cut in permanent flows have brought land subsidence and the death of Gavkhouni to a point of no return and even put drinking water on the threshold of threat,” said Dariush Golalizadeh, the provincial environment department chief.
“The Zayandeh-Roud played a key role in recharging aquifers and preventing subsidence. With multi-year drought and sharply reduced inflows, alongside heavier pumping from wells and wastewater use, subsidence has intensified alarmingly.”
Golalizadeh said the internationally listed Gavkhouni wetland downstream of Isfahan is turning into a dust hotspot. “When the wetland falls apart, it means there are serious problems in water and land management above it.”
He linked the ecological stress to livelihoods, saying orchards, urban green spaces and farmers have been hit across the basin. Authorities are now working on support programs for Isfahan’s eastern districts to soften the blow to agriculture, he said.
The official urged emergency measures to keep minimum flows to the river and wetland.
“At present, because of the sharp drop in river yield, drinking water is under threat,” he said. “We are looking to other sources, but rising temperatures and drought have cut inflows to a minimum.”
