How will declining inflows and regional water stress affect Uzbekistan's water security?
Uzbekistan faces direct implications for water security due to declining regional inflows. The decline in water inflows to reservoirs in Central Asia, including the Shardara Reservoir in Kazakhstan, is linked to significant glacier mass loss and reduced river flows in the region. Because Uzbekistan relies on transboundary water resources for over 80% of its supply, these regional declines have direct implications for the country’s water security. The situation is compounded by the fact that the Amu Darya and Syr Darya, the region’s two major rivers, are crucial for national water and agricultural needs.

How it reaches Uzbekistan
-
Central Asia is experiencing growing pressure on water resources due to declining river flows and below-normal freshwater reserves. Reports indicate significant declines in water inflows to reservoirs in Tajikistan, Uzbekistan, the Kyrgyz Republic, and Afghanistan. Furthermore, glacier mass balance in the region is among the most negative on record, with Tajikistan losing over 10% of its glacier cover and the Kyrgyz Republic losing over 25%.
The full event1independent outlet -
Declining inflows to reservoirs in Central Asia, such as the Shardara Reservoir in Kazakhstan, are part of a broader trend of reduced river flows. This decline is driven by significant glacier mass loss across the region, which generates more than half of the river runoff.

Everything about Syr Darya -
Declining glacier contributions to the upper reaches of the Syr Darya and Amu Darya have direct implications for Uzbekistan’s water security. This vulnerability is heightened by the fact that Uzbekistan depends on transboundary water resources for more than 80% of its water supply.

- Kazakhstan plans to reduce water losses in irrigation canals from 50% to 25% by 2030.astanatimes.com
Why it matters
Water security is a critical issue for Uzbekistan, as its economy and population depend heavily on agricultural irrigation, which relies on the Syr Darya and Amu Darya. The high dependency on external water sources means that regional climate shifts and upstream water management decisions directly translate into risks for its domestic water supply and agricultural output.
This challenge is part of a long-standing regional issue dating back to the collapse of the Soviet unified water system. The current situation is complicated by differing national priorities, with upstream countries like Tajikistan and Kyrgyzstan prioritizing hydropower generation, while downstream countries like Uzbekistan and Kazakhstan rely heavily on the same resources for agriculture.
What we don't know yet
- Will regional cooperation frameworks, such as the 1998 agreement, be updated to reflect current climate conditions and consumption patterns?
- How quickly will the rate of glacier mass loss accelerate or stabilize?
