Sharon B. Megdal is Director of The University of Arizona Water Resources Research Center and C.W. and Modene Neely Endowed Professor in the College of Agriculture and Life Sciences. She also serves as Director of the University of Arizona Water Sustainability Program. Her work focuses on state, regional and transboundary water resources management and policy. She places particular emphasis on how to achieve desired policy objectives in terms of institutional structures and possible changes to them. In 2010, she was named Distinguished Outreach Professor by the University of Arizona, and she serves as an elected member of the Central Arizona Project Board of Directors. Sharon B. Megdal holds a Ph.D. degree in Economics from Princeton University. Robert G. Varady is deputy director of the University of Arizona’s Udall Center for Studies in Public Policy, research professor of environmental policy and of arid lands studies, and adjunct professor of hydrology and water resources. Varady has written extensively on transboundary environmental policy, and on global water initiatives and international water governance. He is a former president of the International Water History Association. Varady obtained his Ph.D. in 1981 in modern history from the University of Arizona, and B.S. and M.S. degrees in mathematics from the City College of New York and Polytechnic Institute of NYU, respectively.Susanna Eden is Assistant Director of the Water Resources Research Center, University of Arizona. She worked internationally as North American coordinator for the UNESCO IHP HELP (Hydrology for Environment, Life and Policy) Program.

• 1. Water Development: Infrastructure and Institutions; 2. Political and Economic Perspectives; 3. Learning from Comparison; 4. Challenges, New and Old: Climate Change and Wastewater; 5. Expanding Water Supplies: Promising Strategies and Technologies.

As global environmental and demographic changes heighten competition for limited water resources, we are thankful for efforts that attempt to harness science to achieve effective water-management policies. Shared Borders, Shared Waters is that rare book that seeks to promote this aim by drawing on the expertise of scientists and practitioners from sometimes-contentious border regions. In spite of its conflict potential, water connects rather than divides, giving us hope for increased cooperation and conflict avoidance. For the arid areas that are the focus of this collection, the book offers the promise of the best of science diplomacy.— András Szöllösi-Nagy, Rector, UNESCO-IHE
