Kazakhstan, Uzbekistan and Tajikistan are negotiating summer water allocations as rising temperatures, agricultural demand and pressure on shared rivers intensify water security concerns across Central Asia.
As summer approaches, Central Asia is once again confronting one of its most persistent challenges: water security.
Kazakhstan, Uzbekistan and Tajikistan have begun negotiations over how to manage supplies during the coming irrigation season amid concerns that southern Kazakhstan could face shortages at the peak of the agricultural cycle.
At the centre of the discussions is the interstate Dostyk Canal, which supplies water to the Maktaaral and Zhetysai districts in Kazakhstan’s Turkestan Region. In one of the country’s most important farming areas, irrigation is not simply a seasonal issue but a condition for agricultural production itself. Cotton, vegetables and melons grown in the region depend heavily on stable water supplies during the hottest months of the year.
Kazakhstan’s Minister of Water Resources and Irrigation, Nurzhan Nurzhigitov, joined officials from Uzbekistan and Tajikistan for a trilateral meeting to discuss water allocations and the operating regime of the Bahri Tojik reservoir between June and August 2026, a period when regional demand for water traditionally reaches its highest point.
For Kazakhstan, the issue extends well beyond agriculture. Water shortages can quickly reduce harvests, squeeze farmers’ incomes and contribute to higher food prices, turning seasonal irrigation into a matter of broader economic importance.
Across Central Asia, negotiations over rivers such as the Syr Darya are becoming increasingly consequential. Hotter summers, rising demand for water, climate change and mounting pressure on transboundary rivers are placing greater strain on already limited resources, making regional cooperation more urgent than ever.
“Year after year, our joint work allows us to ensure a fair distribution of transboundary water resources. Kazakhstan confirms its readiness to continue cooperation to maintain stable water management in the Syr Darya river basin. It is critically important for us that decisions taken reflect the interests of all parties,” Nurzhigitov said.
The consequences extend beyond farming communities. In a region where agricultural output remains closely tied to water availability, disruptions to irrigation can affect harvest volumes, food supply chains and, ultimately, regional food security.
The talks come as water shortages deepen across Central Asia. Scientists warn that agricultural water demand could rise by as much as 30% by 2030, while experts say growing shortages may also affect energy supplies, food production and public health.
At the same time, Kazakhstan is exploring technological ways to reduce the impact of drought. Authorities in Turkestan Region recently launched a project aimed at artificially increasing rainfall, making Kazakhstan the first country in Central Asia to move towards the practical use of weather modification technologies.
The project is intended to improve reservoir levels and stabilise water supplies for agriculture in southern Kazakhstan, particularly in Turkestan Region, where arable land exceeds 911,000 hectares. International estimates suggest cloud-seeding technologies can increase precipitation by between 10% and 20% compared with natural levels.
Officials estimate the initiative could generate an economic benefit of around U.S.$75 million annually through improved water availability, reduced drought risks and stronger crop yields.
