Water Policy and Planning in a Variable and Changing Climate addresses the current challenges facing western water planners and policy makers in the United States and considers strategies for managing water resources and related risks in the future. Written by highly-regarded experts in the industry, the book offers a wealth of experience, and explains the physical, socioeconomic, and institutional context for western water resource management. The authors discuss the complexities of water policy, describe the framework for water policy and planning, and identify many of the issues surrounding the subject.

A provocative examination of policy issues surrounding western water resources, this book:

• Considers the implications of natural climate variability and anthropogenic climate change for the region's water resources, and explains limitations on the predictability of local-scale changes
• Stresses linkages between climate patterns and weather events, and related hydrologic impacts
• Describes the environmental consequences of historical water system development and the challenges that climate change poses for protection of aquatic ecosystems
• Examines coordination of drought management by local, state and national government agencies
• Includes insights on planning for climate change adaptation from case studies across the western United States
• Discusses the challenges and opportunities in water/energy/land system management, and its prospects for developing climate change response strategies
• Presents evidence of changes in water scarcity and flooding potential in the region and identifies a set of adaptation strategies to support the long-term sustainability of irrigated agriculture and urban communities
• Draws upon Colorado's experience in defining rights for surface and tributary groundwater use to explain potential conflicts and challenges in establishing fair and effective coordination of water rights for these resources
• Assesses the role of policy in driving flood losses
• Explores policy approaches for achieving equitable and environmentally responsible planning outcomes despite multiple sources of uncertainty

Water Policy and Planning in a Variable and Changing Climate

describes patterns of water availability, existing policy problems and the potential impacts of climate change in the western United States, and functions as a practical reference for the student or professional invested in water policy and management.

Growing populations, limited water availability, and changing social values have increased the complexity of water resource planning. Water providers and other stakeholders are struggling to understand the impacts of global climate change on water supplies, water demands and vulnerability of source-area environmental resources and socio-ecological systems. This book provides insights on these issues and describes strategies for building adaptive capacity while improving environmental stewardship. It helps readers understand patterns of water availability, existing policy problems and the potential impacts of climate change.

"? presents a synthesis of what leading scientists, lawyers, political scientists and other water professionals know about the likely adverse impacts on the region and how the West might make the hard choices to cope with its changed climate. The book covers the latest scientific understanding of climate change and its impact on the region's hydrology. It gives equal weight to both ends of the risk spectrum-stressed water availability for consumptive and non-consumptive environmental uses as well as more extreme flood events. ? essential reading for all water professionals and anyone interested in the fate of the American West." -Dan Tarlock, Chicago-Kent College of Law, Illinois Institute of Technology, USA "We have always lived with considerable variability in water supply in the western United States. Now the range of uncertainty in water supply planning has increased markedly as a consequence of climate change. This new book provides valuable contributions from a wide array of perspectives to help us better understand the challenges we now face and the responses that will be necessary under these conditions." -Lawrence J. MacDonnell, Senior Fellow, Getches-Wilkinson Center, University of Colorado, Boulder, USA "? the contributors embrace uncertainty in the physical and social systems shaping future water options. This is liberating because it enables new ways of thinking about adaptively managing water sector risks under climate change. They also provide well-grounded and thoughtful critiques of the most significant technical and policy challenges ahead. Most importantly, they give hope to those faced with the daunting task of reforming water planning by giving plenty of examples of how this can be done in practice."-Professor Robert L.
