Uzbekistan introduces “Ice Stupa” artificial glacier technology for the first time

As part of the 31st UN Climate Change Conference (COP31), held in Antalya, Türkiye, Aziz Abdukhakimov, Adviser to the President of the Republic of Uzbekistan on Environmental Issues and Chairman of the National Committee on Ecology and Climate Change, held a meeting with representatives of the UN Food and Agriculture Organization (FAO).

One of the practical areas of cooperation presented at the meeting was the artificial glacier technology (Ice Stupa), introduced in Uzbekistan for the first time.

Why is this needed?

Climate change has made the protection of water resources one of the highest priorities in Central Asia.

According to forecasts, by 2050, water availability could decrease by 30–40 percent, while demand for irrigation water could increase by 25 percent.

The water deficit could rise from approximately 3 billion cubic metres in 2015 to 7 billion cubic metres in 2030 and reach 15 billion cubic metres by 2050.

How does the technology work?

During the cold winter months, water is sprayed upwards through pipes into the air.

The sprayed water freezes and gradually forms a large, cone-shaped ice structure.

The accumulated ice melts in spring and summer, supplying water when demand is at its highest.

Experimental glacier

The first artificial glacier was built in the Sarchashma area of Shahrisabz district, Kashkadarya Region, and became operational in January 2026.

The system operates solely through natural differences in elevation and water pressure, meaning it does not require electric pumps.

During its initial trial, it accumulated approximately 800 cubic metres of ice, which provided meltwater to around 60 local households.
