AbstractCentral Asia is region, where drought is routine condition of life and crop production and agricultural production are adopted to such enormous climatic conditions. The natural deficit of water as difference between precipitation and evaporation deviates from 600800 mm in area of ancient oasis and hillside up to 14001600 mm in desert and steppe. As result of such climate irrigation and water development are two major foundations of sustainable agriculture and water supply, which are oriented on the average indicator of water scarcity in long-term climatic range. Nevertheless, the deviation from those regular indicators of scarcity - precipitation, flow, groundwater level, evapotranspiration - creates the problems, which reacted sharply on crops growing, production market and as result poverty and well-being of the people. Experience of 20002001 - two very water scarce years - showed big influence of abnormal drought on the all life of Aral Sea basin. From this point of view, potential change of climate became one of the principal future issues for 5 states of the region The research was intended to study and demonstrate the possible ways to increase food crop productivity and improve irrigation efficiency under conditions of aridization forecasted for the region. Together with the specialists of MacGill University (Canada) the irrigation and agriculture research in the fields of farms in Uzbekistan , Kazakhstan, Tadjikistan is implemented.
