Book Description
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.

Book Description
Agriculture is the largest user of fresh water in the world. Therefore, any improvement in the efficiency of irrigation water use will result in cost reduction and the possibility of larger irrigated areas. This communication presents a precision irrigation system based on a wireless network of sensors and actuators in which a high level of control is achieved by means of valve automation. Water needs are calculated based on the crop characteristics, soil information, and the design of the irrigation system. Regional real-time weather data were obtained from the California Irrigation Management Information System (CIMIS). A new software system was developed to manage and control multiple valve groups according to different crops and strategies, and to make decisions on when and for how long to irrigate. The system was tested in almonds and walnuts where strategies based on evapotranspiration, stem water potential, and grower opinion were carried out. A total of 36 five-tree units were controlled with valves operated by the control software. Water use, yield, and nut quality were measured to analyze differences between the irrigation strategies. A cost/benefit analysis was also done using current water costs in different California agricultural regions. The use of this variable rate system to control irrigation based on evapotranspiration resulted in water savings of 1,776 m3/ha for almonds and 995 m3/ha for walnuts compared to normal grower control. Despite the reduction of water use, at current water costs these savings will not compensate for the differences in yield.
