DescriptionOver the last dozen years, satellite observations of Earth's water cycle from NASA's GRACE (Gravity Recovery and Climate Experiment) mission have provided an unprecedented view of global hydrological change and freshwater availability. Since its launch, the mission has helped to confirm that precipitation, evaporation and continental discharge rates are increasing, that the mid-latitudes are drying while the high and low latitudes are moistening, and that the hydrologic extremes of flooding and drought are becoming even more extreme. Importantly, GRACE has enabled us to peer beneath Earth's surface and characterize the worldwide depletion of groundwater aquifers, raising significant concerns about the potential for heightened conflict over transboundary water resources. In this talk, Jay Famiglietti reviews his team's recent study of groundwater depletion in the Middle East and places it into a global context of hydrologic change. The results of this study raise many important issues for climate, water, food and economic security, and have implications for the future of water availability and sustainable water resources management in the Middle East and around the world.

Jay Famiglietti is a hydrologist, a professor of Earth System Science and of Civil and Environmental Engineering at the University of California, Irvine, and the Senior Water Scientist at the NASA Jet Propulsion Laboratory at the California Institute of Technology. He was appointed by the Governor of California to the Santa Ana Regional Water Quality Control Board, and he is the Founding Director of the UC Center for Hydrologic Modeling (UCCHM) at UC Irvine. Before joining UCI in 2001, Jay was on the faculty of the Geological Sciences Department at the University of Texas at Austin, where he helped launch the program in climate and the UT Environmental Science Institute. Jay and his team have been researching and communicating about water and climate change — in academics, in business, in government and to the general public — for over 25 years. He appeared as a featured expert in the water documentary Last Call at the Oasis, and he is a regular contributor to National Geographic Water Currents and to Huffington Post. Jay is a frequent speaker, and his research is often featured in the international news media. He is currently working on his first book on climate change, emerging threats to water security, and a modern view of the global water crisis.
