Iran has launched this year’s cloud-seeding operations over the Lake Urmia basin as the country faces one of its worst droughts in decades, with authorities simultaneously urging nationwide rain-seeking prayers as reservoirs run dry and water shortages deepen across major cities.
The Energy Ministry’s atmospheric water technologies organization said the first flight of the 2024–25 water year was conducted on Saturday over northwestern Iran, where Lake Urmia – once the Middle East’s largest saltwater lake – has largely dried into a salt plain after years of drought, over-extraction and extreme heat.
Mohammad-Mehdi Javadianzadeh, who heads the state body, said a specialized aircraft equipped for cloud seeding was deployed as a suitable weather system passed over the region.
He said teams plan to conduct operations “on all incoming systems that are technically viable” and are assessing conditions over Tehran and other provinces to determine whether additional flights can be launched in the coming days.
He said the aim is to maintain continuous operational capacity in the northwest, with authorities planning to base a dedicated aircraft in Tabriz to service both East and West Azarbaijan provinces.
The program is expected to run until mid-May using both aircraft and drones. Cloud seeding, Javadianzadeh added, is internationally recognized as a cost-effective tool for atmospheric water harvesting.
“Cloud seeding has been shown to increase precipitation and is used around the world not only to enhance rainfall but also to suppress hail, disperse fog and increase hydropower reserves,” he said.
But he warned that the technology has limits and requires clear public messaging: “If the issue is not explained properly, expectations beyond the capacity of the technology or disappointment with it may emerge among society and decision-makers.”
Cloud seeding widely used, but not a cure-all
Cloud seeding is used in more than 50 countries, including the United States, China, Australia and several Middle Eastern states. Scientific reviews suggest that under favorable atmospheric conditions the process can boost precipitation by 5 to 15 percent, though results vary widely and remain difficult to measure precisely.
Iran’s neighbors – especially the United Arab Emirates and Saudi Arabia – have expanded large-scale seeding programs, with the UAE carrying out more than 200 missions a year and investing in drone-based techniques similar to those Iran has begun deploying.
Experts say that while cloud seeding can marginally increase rainfall, it cannot compensate for decades of overuse, aquifer depletion and climate-driven aridity across the region.
Prayers for rain held nationwide
The new operations come as Iran faces what water specialists describe as a nationwide emergency. Reservoirs supplying Tehran are at or near historic lows, and authorities warn the capital could face extensive rationing if winter rains fail. Some neighborhoods have already reported intermittent cuts.
This week, cities across Iran held rain-seeking prayers as clerics urged the faithful to perform the traditional salat al-istisqa amid the worsening drought.
In Tehran, worshippers gathered at the Imamzadeh Saleh shrine in the north of the capital on Friday. Similar ceremonies were held in Mashhad, Qom and Qazvin.
Ayatollah Abdollah Javadi Amoli said the prayer is “asking for water in all forms, not just rain,” calling it a moment for repentance and unity as water shortages deepen nationwide.
Experts say Iran is experiencing “water bankruptcy,” a condition in which consumption has exceeded renewable supply after decades of over-pumping, large-scale basin transfers and agricultural expansion.
Northwestern Iran has been among the hardest-hit regions. Lake Urmia’s collapse has triggered expanding salt storms that have damaged farmland and forced some residents to leave nearby villages, according to local media and environmental researchers.
Officials say unauthorized wells and heavy irrigation remain major drivers of groundwater decline.
Meteorological officials say rainfall so far this autumn is nearly 90% below long-term averages, making it the driest season in half a century.
