Book Description
The question of whether the earth's climate is changing in some significant human-induced way remains a matter of much debate. But the fact that climate is variable over time is well known. These two elements of climatic uncertainty affect water resources planning and management in the American West. Managing Water Resources in the West Under Conditions of Climate Uncertainty examines the scientific basis for predictions of climate change, the implications of climate uncertainty for water resources management, and the management options available for responding to climate variability and potential climate change.

Book Description
Phoenix is known as the "Valley of the Sun," while Tucson is referred to as "The Old Pueblo." These nicknames epitomize the difference in the public's perception of each city. Phoenix continues to sprawl as one of America's largest and fastest-growing cities. Tucson has witnessed a slower rate of growth, and has only one quarter of Phoenix's population. This was not always the case. Prior to 1920, Tucson had a larger population. How did two cities, with such close physical proximity and similar natural environments develop so differently?Desert Cities examines the environmental circumstances that led to the starkly divergent growth of these two cities. Michael Logan traces this significant imbalance to two main factors: water resources and cultural differences. Both cities began as agricultural communities. Phoenix had the advantage of a larger water supply, the Salt River, which has four and one half times the volume of Tucson's Santa Cruz River. Because Phoenix had a larger river, it received federal assistance in the early twentieth century for the Salt River project, which provided water storage facilities. Tucson received no federal aid. Moreover, a significant cultural difference existed. Tucson, though it became a U.S. possession in 1853, always had a sizable Hispanic population. Phoenix was settled in the 1870s by Anglo pioneers who brought their visions of landscape development and commerce with them.By examining the factors of watershed, culture, ethnicity, terrain, political favoritism, economic development, and history, Desert Cities offers a comprehensive evaluation that illuminates the causes of growth disparity in two major southwestern cities and provides a model for the study of bi-city resource competition.

Book Description
Following enactment of the Reclamation Act, the first federally constructed dam broke ground in Arizona's Salt River Valley in 1905. With the inauguration of Roosevelt Dam, the distant dream of an abundant life in the desert became a reality. The dam and farmer-operated water distribution system tamed the vicious drought, created arable land and became an irrigation model for the West. With the water came farmers and families, all eager for the chance to build new lives and communities. Many were just like the Haley family, farmers from Kentucky and Missouri who settled in the area and whose descendants still call the valley home. Follow their journey and discover a snapshot of the life and community that grew from the ditches of the valley. Author Meredith Haley Whiteley explores this story from the ordinary person's perspective, weaving valley history through drought, loss, plenty and joy.

Book Description
Recent studies of past climate and streamflow conditions have broadened understanding of long-term water availability in the Colorado River, revealing many periods when streamflow was lower than at any time in the past 100 years of recorded flows. That information, along with two important trends-a rapid increase in urban populations in the West and significant climate warming in the region-will require that water managers prepare for possible reductions in water supplies that cannot be fully averted through traditional means. Colorado River Basin Water Management assesses existing scientific information, including temperature and streamflow records, tree-ring based reconstructions, and climate model projections, and how it relates to Colorado River water supplies and demands, water management, and drought preparedness. The book concludes that successful adjustments to new conditions will entail strong and sustained cooperation among the seven Colorado River basin states and recommends conducting a comprehensive basinwide study of urban water practices that can be used to help improve planning for future droughts and water shortages.

Book Description
Most Americans consider electricity essential to their lives, but the historic disparity of its distribution and use challenges notions of a democratic lifestyle, economy, and culture. By the beginning of the twentieth century, substations, wires, towers, and poles had followed migrants westward as the industrial era?s most prominent symbols of progress and power. When private companies controlled power production, electrical transmission, and distribution without regulation, they argued that it was not ?economically feasible? for many ethnic and rural communities to access ?the grid.? Yet, government agents continued to advocate electrical living through federal programs that reached into and across farming communities and American Indian reservations to homogenize and assimilate them through urban technologies. In the end, however, rural electrification was a locally directed process, subject to local and regional issues, concerns, and parameters. ΓΈ Electrifying the Rural American West provides a social and cultural history of rural electrification in the West. Using three case studies in Arizona, Leah S. Glaser details how, when examined from the local level, the process of electrification illustrates the impact of technology on places, economies, and lifestyles in the diverse communities and landscapes of the American West. As today?s policy-makers advocate building more power lines as a tool to bring democracy to faraway places and ?smart grids? to deliver renewable energy, they would do well to review the historical relationship of Americans with electronic power production, distribution, and regulation.
