The Syrdarya River basin in Central Asia exhibits symptoms of scarcity because of growing competition between hydropower upstream and environment, cities and agriculture downstream. Different approaches to water management, based on water savings in agriculture could relieve the stress of competition, yet keep alive a vibrant agriculture. The Fergana Valley, a highly productive area within the upstream of the Syrdarya River, was analyzed to determine the water savings potential of agriculture. This paper used a water accounting procedure to identify both the scope for savings and the strategies to realize those gains. Signi cant nonproductive depletion of water at 681-4164millionm3 (Mm3) was identi ed in the formof evaporation, ows to sinks and pollution. Thewater-saving potential is estimated at 2823Mm3 annually, which is about 10% of the total in ow into the area, through a range of practical approaches. This strategy would bring regional bene ts by reallocation of surplus winter ow from the upstream for summer use in the downstream.
