Technical Abstract: About 92% of freshwater withdrawals in Uzbekistan are used for irrigation, whereas in the United States, freshwater withdrawls account for about 33% of the total use. In Uzbekistan, most of the water suitable for irrigation has already been allocated. In the United States, groundwater depletion and reallocation of water to higher value uses is reducing the quantity of available irrigation water. In both countries, irrigators are or will be required to reduce water use. Increasing crop water productivity is a major pathway towards sustaining both economies and livelihoods while improving the sustainability of irrigated and rainfed agriculture. This talk presents research opportunities aimed at improving the efficient use of water in Uzbekistan and the arid and semi-arid regions of the United States.
