Book Description

Water managers in Arizona are facing difficulties due to population and urban infrastructure growth. An understanding of water use patterns is critical to the management of urban water resources. This study focuses on estimating spatial and socioeconomic patterns of water users in the Phoenix Metro area through a series of statistical analysis. Using total water use for 2010 as a dependent variable and 36 socioeconomic characteristics as explanatory variables, four statistical methods were used to analyze the relationships: 1) Individual regression analyses, 2) A multivariate regression analysis 3) a principal components analysis (PCA) and 4) a principal components regression. Results show that water users between ages of 55 to 69 by census tract correlated strongest with total water use in 2010. Results of the multivariate regression of seven socioeconomic variables were able to explain 77% of the variability of water use across the study area. PCA analysis identified three components of socioeconomic variables that in combination explained 73% of water use. From the components four specific socioeconomic groups were identified: high income retiree populations, large Hispanic families, high income families, and low to middle income populations. To analyze the spatial clustering of water use and socio-economic data, local index of spatial autocorrelation (LISA) mapping was used. The identified socioeconomic clusters were found to overlay political boundaries. Recommendations presented include possible water use patterns for each identified socioeconomic group and some suggested programs that may be beneficial to water management. LISA results also suggest that addressing intra-city water management to account for the spatial variability of water use their users across political boundaries is important. The analysis presented here may be used as tool to identify broad spatial and statistical water use patterns, but it has limitations to understanding patterns at the level of households.

Book Description

The central challenge for Arizona and many other arid regions in the world is keeping a sustainable water supply in the face of rapid population growth and other competing demands. This book highlights new approaches that Arizona has pioneered for managing its water needs. The state has burgeoning urban areas, large agricultural regions, water dependent habitats for endangered fish and wildlife, and a growing demand for water-based recreation. A multi-year drought and climate-related variability in water supply complicate the intense competition for water. Written by well-known Arizona water experts, the essays in this book address these issues from academic, professional, and policy perspectives that include economics, climatology, law, and engineering. Among the innovations explored in the book is Arizona‘s Groundwater Management Act. Arizona is not alone in its challenges. As one of the seven states in the Colorado River Basin that depend heavily on the river, Arizona must cooperate, and sometimes compete, with other state, tribal, and federal governments. One institution that furthers regional cooperation is the water bank, which encourages groundwater recharge of surplus surface water during wet years so that the water remains available during dry years. The Groundwater Management Act imposes conservation requirements and establishes planning and investment programs in renewable water supplies. The essays in Arizona Water Policy are accessible to a broad policy-oriented and nonacademic readership. The book explores Arizona‘s water management and extracts lessons that are important for arid and semi-arid areas worldwide.

Book Description

Cities in the arid West would not be what they are today without water and the technology needed to deliver it to users. The history of water development in Arizona goes hand in hand with the state's economic growth, and Arizona's future is inextricably tied to this scarce resource. Fuel for Growth describes and interprets the history of water resource development and its relationship to urban development in Arizona's three signature cities: Phoenix, Tucson, and Flagstaff. These three urban areas could hardly be more different: a growth-oriented metropolis, an environmentally conscious city with deep cultural roots, and an outdoor-friendly mountain town. Despite these differences, their community leaders and public officials have taken similar approaches to developing water resources with varying degrees of success and acceptance. Douglas Kupel has created a new vision of water history based on the Arizona experience. He challenges many of the traditional assumptions of environmental history by revealing that the West's aridity has had relatively little impact on the development of municipal water infrastructure in these cities. While urban growth in the West is often characterized as the product of an elite group of water leaders, the development of Arizona's cities is shown to reflect the broad aspirations of all their citizens. The book traces water development from the era of private water service to municipal ownership of water utilities and examines the impact of the post-World War II boom and subsequent expansion. Taking in the Salt River Project, the Central Arizona Project, and the Groundwater Management Act of 1980, Kupel explores the ongoing struggle between growth and environmentalism. He advocates public policy measures that can sustain a water future for the state. As the urban West enters a new century of water management, Arizona's progress will increasingly be tied to that of its ever-expanding cities. Fuel for Growth documents an earlier era of urban water use and provides important recommendations for the future path of water development in the West's key population centers.

Book Description

The desire for economic growth in Phoenix, Arizona has promoted the growth of the citys population and the expansion of the city itself. Phoenix has grown from a small desert town into one of the largest cities in the United States. Phoenixs economic development after World War II enabled it to retain its workforce and employers, while attracting new workers and companies.However, Phoenix is located in the desert of the Salt River Valley in Central Arizona. Phoenix has always had to face the challenge of water security. The emergence and intensification of climate change will force the city to struggle even more in the 21st century as the population increases and demand for fresh water grows, while supply remains scarce. 1) This thesis will argue that population growth and a political system that prioritizes economic growth have been, and will continue to be, the catalysts for Phoenixs increasing water demand. Phoenixs population has grown unchecked because of the desire for economic growth, and the lack of population control measures. 2) This thesis will also argue that Phoenixs city officials have not adequately addressed the threats to water supply that are posed by population growth. 3) This thesis will argue that the city government ultimately bears responsibility for any impending water shortages that the city will face in the 21st century. 4) Finally, this thesis will use historical water consumption data to examine quantities of water that could have been conserved if water demand levels had been lower at earlier times in Phoenixs history.

Book Description

Phoenix, Arizona is one of America's fastest growing metropolitan regions. It is also its least sustainable one, sprawling over a thousand square miles, with a population of four and a half million, minimal rainfall, scorching heat, and an insatiable appetite for unrestrained growth and unrestricted property rights. In Bird on Fire, eminent social and cultural analyst Andrew Ross focuses on the prospects for sustainability in Phoenix--a city in the bull's eye of global warming--and also the obstacles that stand in the way. Most authors writing on sustainable cities look at places that have excellent public transit systems and relatively high density, such as Portland, Seattle, or New York. But Ross contends that if we can't change the game in fast-growing, low-density cities like Phoenix, the whole movement has a major problem. Drawing on interviews with 200 influential residents--from state legislators, urban planners, developers, and green business advocates to civil rights champions, energy lobbyists, solar entrepreneurs, and community activists--Ross argues that if Phoenix is ever to become sustainable, it will occur more through political and social change than through technological fixes. Ross explains how Arizona's increasingly xenophobic immigration laws, science-denying legislature, and growth-at-all-costs business ethic have perpetuated social injustice and environmental degradation. But he also highlights the positive changes happening in Phoenix, in particular the Gila River Indian Community's successful struggle to win back its water rights, potentially shifting resources away from new housing developments to producing healthy local food for the people of the Phoenix Basin. Ross argues that this victory may serve as a new model for how green democracy can work, redressing the claims of those who have been aggrieved in a way that creates long-term benefits for all. Bird on Fire offers a compelling take on one of the pressing issues of our time--finding pathways to sustainability at a time when governments are dismally failing in their responsibility to address climate change.

Book Description

This dissertation demonstrates the importance and necessity of incorporating spatio-temporal components, such as scale, dependence, and heterogeneity, into SFR water use research. Spatial statistical models should be used to understand the effects of associated factors on water use and test the effectiveness of certain management policies since spatial effects probably will significantly influence the estimates if only non-spatial statistical models are used. Urban water demand management should pay attention to the spatial heterogeneity in predicting the future water demand to achieve more accurate estimates, and spatial statistical models provide a promising method to do this job.

Book Description

Science Be Dammed is an alarming reminder of the high stakes in the management—and perils in the mismanagement—of water in the western United States. It seems deceptively simple: even when clear evidence was available that the Colorado River could not sustain ambitious dreaming and planning by decision-makers throughout the twentieth century, river planners and political operatives irresponsibly made the least sustainable and most dangerous long-term decisions. Arguing that the science of the early twentieth century can shed new light on the mistakes at the heart of the over-allocation of the Colorado River, authors Eric Kuhn and John Fleck delve into rarely reported early studies, showing that scientists warned as early as the 1920s that there was not enough water for the farms and cities boosters wanted to build. Contrary to a common myth that the authors of the Colorado River Compact did the best they could with limited information, Kuhn and Fleck show that development boosters selectively chose the information needed to support their dreams, ignoring inconvenient science that suggested a more cautious approach. Today water managers are struggling to come to terms with the mistakes of the past. Focused on both science and policy, Kuhn and Fleck unravel the tangled web that has constructed the current crisis. With key decisions being made now, including negotiations for rules governing how the Colorado River water will be used after 2026, Science Be Dammed offers a clear-eyed path forward by looking back. Understanding how mistakes were made is crucial to understanding our contemporary problems. Science Be Dammed offers important lessons in the age of climate change about the necessity of seeking out the best science to support the decisions we make.
