More efficient water use

Central Asia does not really suffer from the lack of water - inefficient use of the resource is the real problem. See e.g. GIWA Regional Assessment on the Aral Sea Basin. How to improve the efficiency of water supply and use? Focus on demand management is needed. Basin-wide monitoring, new facilities, less water consuming crops and cultivation methods, benefit sharing instead of quarelling about regional water allocations - what do you think of these proposals, who could make the difference? What else is needed? Join the discussion!
