Water Use Efficiency Symposium

Learn from and interact with experts from across North America, Europe and Australia about increased water use efficiency, recent advances in grapevine water relations, irrigation technology, and water policy and politics. Speakers will address approaches to manage limited water and salinity, including use of reclaimed water. Grapevine responses to drought will be discussed as well as opportunities to improve water use efficiency through plant breeding, soil and vine monitoring, and irrigation scheduling. The session will conclude with a panel discussion focused on the increasingly important topic of water policy.
