A senior Iranian water expert warned on Sunday that the country’s central plateau could be emptied of inhabitants if authorities fail to address the worsening water crisis, as officials in Tehran admit that rationing in the capital began too late to avert shortages.
Ali Moridi, head of the Water, Wastewater and Environmental Engineering Department at Shahid Abbaspour University of Water and Power Industry, said Iran’s water emergency stemmed not only from its arid climate but from a chronic disconnect between scientists, industry, and government agencies.
“If the current situation continues, it is not unlikely that Iran’s central plateau will become depopulated,” Moridi told reporters at a university briefing.
Moridi cited research linking groundwater depletion and soil salinity to rural migration in southern provinces such as Fars, where vanishing wells have pushed villagers toward cities, worsening urban sprawl and social pressures.
“Many rural communities with high migration rates were directly affected by falling groundwater levels and the salinization of drinking water,” he said.
He urged stronger cooperation between academia and policymakers and showcased a new university-led “biochar” project that converts agricultural waste into a soil additive capable of reducing water use in farming – a sector that consumes over 80 percent of Iran’s water.
“The project must move from the lab to the field,” he said. “Reducing agricultural water use is vital if Iran is to survive this crisis.”
Nationwide emergency
Moridi’s comments come as Tehran faces unannounced nightly water cuts, with reservoirs at record lows and drought conditions worsening across 20 provinces.
The Karaj Dam, one of the capital’s main suppliers, has dropped to less than 10 percent of capacity, officials said this week.
Energy Minister Abbas Aliabadi said on Saturday that some of the city’s pipeline infrastructure was “over 100 years old and severely damaged,” forcing the government to cut nighttime supply to prevent network collapse.
President Masoud Pezeshkian warned earlier this week that Tehran could face mass evacuation if the drought persists through winter. “If it doesn’t rain, we will have no water,” he said.
Meteorologists say the country has entered one of its driest 50-year periods, with rainfall down more than 85 percent compared with last year.
The National Drought Crisis Center has classified the situation as “severe,” warning that no significant rain is forecast for at least ten days.
