A Soviet-era water scheme returns as a Eurasian lifeline |
For decades, the idea of redirecting a small share of Siberia’s vast freshwater resources toward Central Asia has been considered a relic of Soviet-era ambition. Recently, however, the proposal has gained renewed interest, as the underlying realities have changed: Central Asia’s water crisis is rapidly becoming existential, while Russia’s water surplus has increased to such an extent that it now poses environmental risks of its own.
The convergence of climate, economic and geopolitical crises, together with recent technological advances, has transformed this once-impractical proposal into an urgent policy priority. The Earth Sciences Division of the Russian Academy of Sciences recently announced plans to assess the feasibility of redirecting 1% to 2% of the Ob River’s annual flow to Central Asia.
This figure is deliberately modest. Siberian rivers discharge roughly 3,000 cubic kilometers (792 trillion gallons) of freshwater into the Arctic Ocean and the proposed diversion — about 20 to 70 cubic kilometers — would have virtually no impact on Russia’s vast water reserves. But for countries like Kazakhstan and Uzbekistan, it could be transformative.
The scientific rationale for such a project is straightforward. Climate change has steadily increased Siberian river runoff by roughly six cubic kilometers per year, thereby accelerating Arctic ice melt, coastal erosion and permafrost thaw. Consequently, Russia finds itself in a paradoxical situation: an overabundance of water in the north while its southern regions — particularly the Volga basin — are growing increasingly........
