Kazakhstan’s Looming Water Shortage Puts Development Plans at Risk

Kazakh Officials Seek Aid From International Lenders As Rivers, Reservoirs And Old Canals Strain Under Growing Demand

Kazakh authorities, together with the United Nations Development Programme and several multilateral lenders, are scrambling to blunt a fast-growing water shortfall that analysts say could undercut the country's economic goals. UNDP projections indicate the country could face up to half of its water needs missing by 2040, and that the shortfall may shave roughly one out of every 20 dollars from gross domestic product by midcentury if unchecked. Government sources say the shortage is now a central factor in planning for future power, industry and farming investments.

Much of the problem springs from Kazakhstan's dependence on rivers that originate beyond its borders. Nearly half of the inflow that feeds Kazakh waterways comes from neighboring states, including China, putting Kazakhstan at the mercy of upstream water use and policymaking. "When water supply is unstable, it becomes a binding constraint on growth in the same way that lack of financing or electricity would," said Alikhan Sadyrov, an Almaty-based economist who studies resource risks. He urged faster regional talks on allocation and shared infrastructure to prevent unilateral reductions upstream from cascading into domestic shortages.

Large-scale energy projects illustrate the stakes. Plans to build a nuclear power station on the shore of Lake Balkhash — billed by officials as a keystone for energy security — have raised unease among hydrologists and planners who warn that falling lake levels could complicate cooling requirements and long-term operations. Local engineers argue that siting major thermal or nuclear facilities without stronger guarantees about water availability creates long-lived exposure to climate and regional demand shifts.

Aging irrigation systems amplify the squeeze. UNDP and local ministry assessments show only about a third of irrigation channels use modern water-saving methods, and roughly half of canals are in poor condition. Of each 1 million cubic meters drawn from rivers, only about 40 to 45 percent reaches fields, compared with a roughly 70 percent standard in better-performing systems; losses can reach as much as three-fifths of supplies. Irrigated yields in Kazakhstan run two to four times below comparable countries, putting the farming sector — a major employer — at risk of lower output and income unless efficiency improves.

Multilateral development banks have begun funding upgrades. In late 2024 the Islamic Development Bank rolled out a program worth about $1.15 billion to strengthen institutional water-management capacity, build storage, expand new technologies and rehabilitate canals. The Eurasian Development Bank approved a roughly $5.3 million grant late last year to create regional irrigation centers and improve hydrological forecasting. Officials say an implementation phase is underway, but observers note that hardware fixes must be paired with pricing reform, leak repairs, incentives for drip irrigation and better water accounting to deliver durable gains.

Astana will host a regional environmental summit April 22–24 that organizers hope will weld together national, regional and international responses to these pressures. Policymakers face a narrow window: invest quickly in both infrastructure and governance, or accept meaningful constraints on industrial expansion and rural livelihoods. Farmers, energy planners and urban utilities are already adjusting to tighter supplies — and the speed of the national response will determine whether Kazakhstan can sustain its modernization agenda or see growth plans deferred.
