EPA is releasing a Synthesis Report on the Importance of Water to the U.S. Economy. This report is intended to help raise the awareness of water’s importance to our national economic welfare, and to summarize information that public and private decision-makers can use to better manage the nation’s water resources. It highlights EPA’s review of the literature and practice on the importance of water to the U.S. economy, identifies key data gaps, and describes the implication of the study’s findings for future research. EPA hopes this report will be a catalyst for a broader discussion about water’s critical role in the U.S. economy.
Water is vital to a productive and growing economy in the United States, and directly affects the production of many goods and services. While some data are available about how important clean and available water is to various economic sectors--including agriculture, tourism, fishing, manufacturing, and energy production -- the information is often dispersed and incomplete. Additionally, understanding the economic significance of water is difficult because it depends upon several interacting elements: the volume supplied, where and when it is supplied, whether the supply is reliable, and whether the quality of the water meets the requirements of its intended use.
Check out these recent articles regarding the science policy interface in Nature and The Guardian.
Policy: Twenty tips for interpreting scientific claims, by William J. Sutherland, David Spiegelhalter, and Mark Burgman. Published November 20,2013. Calls for the closer integration of science in political decision-making have been commonplace for decades. However, there are serious problems in the application of science to policy — from energy to health and environment to education.This list will help non-scientists to interrogate advisers and to grasp the limitations of evidence.
British and Australian scientists compile a list of tips to help policy makers better understand the 'imperfect nature of science'. Politicians lack the skills to properly interpret and analyse science, according to a group of Australian and British scientists who have compiled a list of 20 tips for MPs to ponder. The tips, published in Nature, have been compiled by William Sutherland, a zoologist, and David Spiegelhalter, a mathematician – both are from the University of Cambridge – and Mark Burgman, an ecologist at the University of Melbourne. The trio argue the "immediate priority is to improve policy makers’ understanding of the imperfect nature of science" by suggesting 20 concepts that should be taught to government ministers and public servants.
There are some common misunderstanding among scientists about how governments make their policy decisions. When scientists moan about how little politicians know about science, I usually get annoyed. Such grouching is almost always counterproductive and more often than not betrays how little scientists know about the UK's governance structures, processes, culture and history. So when the Guardian reported on a Nature article that listed 20 things that politicians should know about science, I started reading it with apprehension, half expecting my head to explode within a few paragraphs.
We've had 20 things politicians need to know about science and 20 things scientists need to know about policy. Where's the rest of society fit into this? We have had the Top 20 things politicians need to know about science and the Top 20 things scientists need to know about policy-making. But where does the rest of society fit into this? People can easily become invisible in the discourse between policy wonks and scientists, or they are regarded as barriers to ‘acceptance’ of whatever particular policy or technology is the flavour of the moment. That is simplistic of course because there are multiple ways in which people can and do have their voice within our democracy, but in the interest of balance here is a complementary list. There are only 12 of them, because 20 are too many. The evidence for these derives from the public dialogues evaluated by Sciencewise alongside public attitude surveys and direct personal experience of public engagement over many years.

This study investigates the impact of urban form and landscaping type on the mid-afternoon microclimate in semi-arid Phoenix, Arizona. The goal is to find effective urban form and design strategies to ameliorate temperatures during the summer months. We simulated near-ground air temperatures for typical residential neighborhoods in Phoenix using the three-dimensional microclimate model ENVI-met. The model was validated using weather observations from the North Desert Village (NDV) landscape experiment, located on the Arizona State University’s Polytechnic campus. The NDV is an ideal site to determine the model’s input parameters, since it is a controlled environment recreating three prevailing residential landscape types in the Phoenix metropolitan area (mesic, oasis, and xeric). After validation, we designed five neighborhoods with different urban forms that represent a realistic cross-section of typical residential neighborhoods in Phoenix. The scenarios follow the Local Climate Zone (LCZ) classification scheme after Stewart and Oke. We then combined the neighborhoods with three landscape designs and, using ENVI-met, simulated microclimate conditions for these neighborhoods for a typical summer day. Results were analyzed in terms of mid-afternoon air temperature distribution and variation, ventilation, surface temperatures, and shading. Findings show that advection is important for the distribution of withindesign temperatures and that spatial differences in cooling are strongly related to solar radiation and local shading patterns. In mid-afternoon, dense urban forms can create local cool islands. Our approach suggests that the LCZ concept is useful for planning and design purposes.

In anticipation of its 10-year anniversary, Arizona State University’s Decision Center for a Desert City (DCDC) has released a major new report, "Advancing Science in Support of Water Policy and Urban Climate Change Adaptation at Arizona State University’s Decision Center for a Desert City: A Synthesis of Interdisciplinary Research on Climate, Water, and Decision-Making Under Uncertainty." The report summarizes the center’s major achievements in research, education, and community and institutional outreach since its founding in 2004.
Funded by the National Science Foundation (NSF) and organized under ASU’s Global Institute of Sustainability, DCDC is focused on water sustainability, urban climate adaptation, and decision-making under uncertainty. The center pursues research, in close collaboration with stakeholders, to create a more sustainable future. Research and modeling efforts analyze interacting factors such as population growth and economic development, climate change and variability, water supplies and demands, and governance to inform water management and other environmental decisions among diverse stakeholders.
This report was authored by co-investigators Kelli Larson, Dave White, Pat Gober, Craig Kirkwood, V. Kerry Smith, Margaret Nelson, and Charles Redman, along with research professional Sally Wittlinger.
"This synthesis of DCDC findings was essential for us to back up and say, ‘What have we learned from it all, and where are we going next?’" says Kelli Larson, the report’s lead author and a co-principal investigator at DCDC.
Since its founding, DCDC participants have published over 340 peer-reviewed journal articles and book chapters and supported 69 graduate students who have authored 18 doctoral dissertations and 17 master’s theses. In addition, more than 70 undergraduate students have been involved in DCDC’s research through the Internship for Science-Practice Integration, the Community of Undergraduate Scholars program, and other research assistantships.
"The most challenging and complex sustainability problems facing society today—like climate change—require a new approach to science," says Dave White, DCDC principal investigator and co-director. "We must combine interdisciplinary science within the university with meaningful stakeholder engagement. This ‘transdisciplinary’ approach is reflected in the report, which synthesizes DCDC’s most important findings across a diverse range of disciplines and identifies the most pressing new issues."
The report recaps the history and role of DCDC within scientific and policy dialogue and then plunges into the research results that have been produced over the years. A major theme is the challenge for cities to provide and maintain secure and reliable water supplies despite an uncertain future that will likely include warming temperatures, reduced precipitation, and more extreme weather events such as droughts, fires, and floods.
"Key findings across DCDC research have revealed uneven spatial and social vulnerabilities to water scarcity and other risks, as well as inevitable tradeoffs and uncertainties in decision-making," Larson says. "To cope with the complexities of environmental change, collaborations, and social learning across different actors—such as scientists and policy makers, water managers and land use planners—is essential for urban sustainability."
The report covers topics ranging from climate models used to predict how climate change affects water supplies and demands to analyses on risk perceptions and policy attitudes regarding water resource sustainability. DCDC participants have also contributed substantially to the ASU portfolio of research into climate dynamics including the potential for climate change scenarios to affect regional water resources, in addition to localized urban heat island (UHI) effects and especially their impact on water resources. This work has involved analyzing how urban land-use and land-cover patterns interact with climatic factors to affect water demands.
One of the signature products of DCDC, WaterSim, is described in detail in the report. WaterSim is a systems dynamics model used by researchers, educators, and decision-makers to explore scenarios of climate change, population growth, and how policy choices could alter water supply and demand in central Arizona.
Since its inception, DCDC has served as a type of "boundary organization" designed to bring together academic researchers with diverse stakeholders to ensure that science is not only credible, but also relevant for decision-making. In this role, DCDC has engaged with its partners through educational activities including joint research projects and collaborative workshops. Many of these activities are highlighted throughout the report.
Arizona Republic environmental reporter Brandon Loomis investigates the wicked problem of keeping or destroying Glen Canyon Dam, a decision that seems to have no positive outcomes. Water managers, some scientists, and activists would like to see the dam removed in order to drain Lake Powell and feed a drought-stricken Lake Mead, a water source for major cities including Las Vegas and Phoenix. Draining Lake Powell would also return Glen Canyon to its former, natural glory.
However, some suggest negative consequences if the dam is to be removed. ASU’s Decision Center for a Desert City co-director and senior sustainability scientist Dave White says removing Glen Canyon Dam would rid thirsty cities of a captured and stored water supply.
"(Dam removal) would be fairly catastrophic," White says. "We have too much demand on an annual basis to be met by the natural in-flow of the river."
He says if anything, Glen Canyon Dam would be re-designed, improved, and repaired.
October 16, 2013 - Effective Communication of Scenarios and Scenario Analysis for Decision Making
Scenarios are one method to describe the complexity and uncertainty inherent within the management of complex systems.
The development and analysis of these scenarios is an effective method to synthesize simple facts about a system’s complexity and uncertainty that can be used as a guide for decisionmaking.
Our panelists will focus on how to communicate effectively scenarios and scenario analysis to a wide audience of the general public, policy professionals, and political decision makers in order to facilitate effective and sustainable system management.

De facto wastewater reuse is the incidental presence of treated wastewater in a water supply source. In 1980 the EPA identified drinking water treatment plants (DWTPs) impacted by upstream wastewater treatment plant (WWTP) discharges and found the top 25 most impacted DWTPs contained between 2% and 16% wastewater discharges from upstream locations (i.e., de facto reuse) under average streamflow conditions. This study is the first to provide an update to the 1980 EPA analysis. An ArcGIS model of DWTPs and WWTPs across the U.S. was created to quantify de facto reuse for the top 25 cities in the 1980 EPA study. From 1980 to 2008, de facto reuse increased for 17 of the 25 DWTPs, as municipal flows upstream of the sites increased by 68%. Under low streamflow conditions, de facto reuse in DWTP supplies ranged from 7% to 100%, illustrating the importance of wastewater in sustainable water supplies. Case studies were performed on four cities to analyze the reasons for changes in de facto reuse over time. Three of the four sites have greater than 20% treated wastewater effluent within their drinking water source for streamflow less than the 25th percentile historic flow.
The border region of southern Arizona and Sonora, Mexico faces the sustainability challenges of a semi-arid climate that experiences long periods of water scarcity. Economic, social and political cooperation will be required for the neighboring states to ensure the viability of their water resources in the future, says Arizona State University engineer Enrique Vivoni.
Vivoni is an associate professor in the School of Sustainable Engineering and the Built Environment, one of ASU’s Ira A. Fulton Schools of Engineering, and in the School of Earth and Space Exploration in ASU’s College of Liberal Arts and Sciences. Vivoni also is a researcher with Decision Center for a Desert City.
This summer, the program brought together 11 ASU students and 13 students from three Mexican universities (the Universidad de Sonora, the Instituto Tecnologico de Sonora and the Universidad Autonoma de Ciudad Juarez), along with 14 faculty members from ASU and other universities to gain a deeper understanding of the water scarcity problem in the Arizona-Sonora border region.
The group included professors and students in the fields of civil and environmental engineering, geology, ecology, agriculture, environmental science and global health.
Lessons in water conflicts
Their endeavor started with a week at ASU, where students spent time "organizing travel logistics, getting to know each other, preparing equipment and familiarizing themselves with the state of Sonora and the current water infrastructure," explains Nolie Pierini, an ASU engineering doctoral student.
In the second week, students traveled to Mexico to learn about a major ongoing water dispute in Hermosillo, the largest city in Sonora and the state’s capitol, which has experienced significant population growth in the past decade. To meet the city’s increasing water demand, officials constructed a 162-kilometer-long aqueduct to transfer water from the Yaqui River Basin, a major supplier of water, to agricultural users in Ciudad Obregon.
"It's a commonly seen water conflict between industrial water users and agricultural water users," says Matthew Thompson, who is pursuing a master’s degree in civil engineering at ASU. "The problem is amplified in the case of Sonora because they are in an area with significant drought and not enough water to meet everyone’s needs."
Hydrology field studies
Students visited both Hermosillo and Ciudad Obregon, and heard discussions and presentations from those on both sides of the water debate. They took field trips to an aqueduct, a dam and reservoir, a hydroelectric power plant and a water treatment plant – all parts of water infrastructure in the state of Sonora.
After a week of tours and presentations from water policymakers and stakeholders, the students traveled to the nearby rural city of Rayón for a week of hydrology field research.
One research project, led by David Gochis, a scientist with the National Center for Atmospheric Research in Boulder, Colo., involved attaching radiosonde sensors to large helium weather balloons to track various atmospheric conditions at altitudes as high as 20 kilometers (65,600 feet) at various times of the day. The radiosonde measures temperature, humidity and pressure in the atmosphere, data that is sent directly to a laptop computer and then used to create an atmospheric model that tracks monsoon-season weather dynamics and patterns.
Another project, led by Agustin Robles-Morua, a professor at the Instituto Tecnologico de Sonora and a former postdoctoral researcher at ASU, surveyed people living in Rio San Miguel about water use practices, water quality and the impacts of new infrastructure.
Seth Morales, an ASU senior civil engineering major who is fluent in Spanish, was able to lead his group as they learned about different perspectives of water management and the water-use practices of specific users in the Rio San Miguel area near the town of Rayón.
ASU student Thompson, who worked with a team to install a weir (a barrier placed in a channel to enable measurement of water discharge) in a small stream, says he liked the hands-on aspect of the project. "It was gratifying to go to a remote, cool area and to use our hands to get a job done," he says.
Seeing impact of research
Ara Ko, an ASU engineering doctoral student supervised by Vivoni, worked with water plant pressure chambers under the direction of Instituto Tecnologico de Sonora faculty member Enrico Yepez. Ko says she liked learning about semi-arid plant dynamics and exploring a climate and an ecosystem that is extremely different from her hometown in Korea.
Many of the students say learning about the region’s water issues during their first week in Mexico made the research experience more rewarding.
"Research like we did in Rayón can help us learn how to use water more efficiently and can ease future problems in water policy," Pierini says.
"It was surprising to see how the research, or lack of research, can really have an impact on a whole community," Morales says.
Along with gaining a renewed appreciation for thorough research, the ASU students say they enjoyed learning about a different culture.
"It was amazing to see people living in the same hot summer climate as in Arizona, but without abundant water resources," Morales says. "Some homes only have access to water every three days for a two-hour window."
Along with making him more appreciative of the quality of water infrastructure in the United States, Morales says the program was a "turning point" for him. The experience led him to decide that hydrosystems engineering is the career path he wants to pursue.
Thompson, a self-proclaimed lover of the hot Sonoran desert climate, says he is glad he had the opportunity to get to know some of his "neighbors to the south." He enjoyed learning about the government, culture, universities and people in Mexico, and says he was surprised that he formed a bond with people in Mexico, despite the language barrier.
"It definitely forces you out of your comfort zone, which is something that is essential for anyone who wants to learn how to coexist with people from other cultures," Thompson says.
Adds Morales, "Interaction with another culture opens your mind and impacts the way you view science in general."
Moving Forward to Address Challenges Identified in the Study
In 2012, the Bureau of Reclamation, in partnership with the seven Colorado River Basin States, published the most comprehensive study of future supplies and demands on the Colorado River ever undertaken. The Colorado River Basin Water Supply and Demand Study confirmed what most experts knew: there are likely to be significant shortfalls between projected water supplies and demands in the Colorado River Basin in coming decades.
On May 28, 2013, Department of the Interior Assistant Secretary for Water and Science Anne Castle and Bureau of Reclamation Commissioner Michael L. Connor convened key stakeholders representing the Basin States, Native American Tribes, and the conservation community to discuss the future of the Colorado River Basin. The Moving Forward event in San Diego, California, identified next steps to address actions identified in the Study.
Those who rely on the Colorado River and its tributaries are committed to approaching these future challenges with the same steadfastness that they have approached and overcome past challenges. Following the call to action of the Study and as a first step in that commitment, all that rely on the Colorado are taking initial steps — working together — to identify positive solutions that can be implemented to meet the challenges ahead.
Next Steps - Phase 1
Phase 1 of the Next Steps activities includes the formation of a Coordination Team and three Workgroups with members who represent federal, state, tribal, agricultural, municipal, hydropower, environmental and recreational interests. The Coordination Team directs and reviews the efforts of the three workgroups, which are listed below. Each workgroup consists of members with subject-matter expertise from various entities in an effort to bring important and varying perspectives to build on collaborative findings to pursue the next steps identified in the Study.
This paper evaluates whether the property value capitalization effects measured with quasi-experimental methods offer reliable estimates of willingness to pay for changes in amenities. We propose the use of a market simulation as a robustness check. Two applications establish the method’s relevance. The first examines the conversion of land cover from desert to wet landscape. The second examines cleanup of hazardous waste sites. We find that even when quasi-experimental methods have access to ideal instruments, their performance in measuring general equilibrium willingness to pay cannot be assumed ideal. It needs to be evaluated considering the specific features of each application.
There is a fundamental distinction between estimating the effect of a policy that influences the value of a parcel on that land’s price and estimating what an individual would be willing to pay to obtain the policy. This issue is important to nearly all of the reduced form quasi-experimental (QE) and hedonic property value analyses conducted over the past decade. This distinction arises because the source of identifying information used to avoid biases in hedonic estimates that can arise from omitted variables and sorting behavior is not neutral to the economic interpretation of what is measured.1 Two approaches have been used to evaluate the empirical significance of this logical distinction in recovering estimates of economic trade-offs associated with a change in a nonmarket service. The first uses analytical models to describe the properties of these trade-off estimates, using the evaluation logic often associated with quasi experiments.2 The second approach uses simulation methods to evaluate the quantitative importance of distinguishing specific types of changes in site-specific amenities and [End Page 413] compares the evaluation logic to conventional cross-sectional hedonic methods.
The theoretical analysis by Kuminoff and Pope (2012) is an example of the first strategy. They adapt the Tinbergen-and-Jan-1959Tinbergen (1959)-Epple (1987) description of the features of a hedonic price function to describe a hedonic equilibrium. With this model they demonstrate that for an infinitesimal, exogenous change in a spatial attribute, conveyed with a house, the prechange and postchange marginal willingness to pay (MWTP) measures will be equal and correspond to the incremental price capitalization. However, in other situations the price differential associated with capitalization may not correspond to either the prechange or the postchange MWTP. In evaluating policies that are inherently nonmarginal, the close relationship between capitalization and willingness to pay (WTP) may not hold. In the current paper, we use simulation methods originating in the logic developed by Cropper, Deck, and McConnell (1988) and Kuminoff, Parameter, and Pope (2010) to provide a strategy for developing an understanding of this relationship as it arises in each specific type of application. An economic model, calibrated to a specific market, is used to simulate different hedonic equilibria and then to evaluate the performance of conventional cross-sectional hedonic models and methods based on the logic of program evaluation for estimating specific trade-offs people would make in response to changes in spatially varying amenities.
Our analysis complements the existing hedonic simulation papers and extends them to demonstrate how a market simulation can serve as a robustness check on the maintained assumptions of the evaluation logic when it is used to develop measures in property value applications of the trade-offs a person would make to secure more of a desirable amenity. For small changes, analysts have interpreted these measures as point estimates of the MWTP. For large, discrete changes associated with some applications of the evaluation framework, the appropriate interpretation of these measures is a topic of debate. Our analysis provides additional guidance on the interpretation of these measures. We focus on situations where the measure of interest is the general equilibrium willingness to pay (GE WTP) for changes in amenities, which is often the goal of policy analysis. We present two examples to illustrate the importance of a simulation check. Our findings in these examples imply that quasi experiments that are routinely a part of the evaluation logic can have large errors when their estimates of price capitalization are treated as estimates of WTP. We also find that the use of instruments with cross-sectional hedonic modeling can improve the quality of the estimates for the WTP for discrete changes in amenities. This is true even when the changes are large enough to induce re-sorting and result in a new hedonic price function. Finally, we find that the context for each application matters, so that general conclusions about robust strategies for estimating GE WTP do not follow; and therefore, it would be prudent to consider the use of similar simulations as a complement to empirical research on a case-by-case basis.

Advancing Climate Adaptation in Flagstaff: Expert Discussion Session
On August 20, 2013 at the Global Institute of Sustainability, in preparation for workshops with Flagstaff's Public Works and Police Departments, a team of researchers is convening a small workshop with experts on climate and health, transportation materials, fire, storm water management, and emergency management. This discussion session will lead to a deeper understanding of the critical issues faced by the two departments. The Flagstaff City Council recently adopted strategies based upon the City’s 2012 City of Flagstaff Resiliency and Preparedness Study. Flagstaff’s management team hopes to implement these strategies through its performance measure and budgeting processes. The University of Arizona’s Climate Assessment for the Southwest (CLIMAS) program and Arizona State University’s Decision Center for a Desert City (DCDC) and Center for Integrated Solutions to Climate Challenges is assisting the City in this process. The team will work with Flagstaff’s management team to convene workshops targeted at the police and public works departments. The goals for the workshops will be to identify adaptation strategies that can be implemented now and planned for in the medium- and long-terms as climate and social conditions evolve. Once these strategies have been identified, we will develop performance measures and progress indicators for each strategy.
Expert Discussion Session Objectives
Document expert opinions on how human vulnerability as they relate to health, storm water drainage, street pavement, forest fire, population, and emergency managers will be impacted by climate changes (impacts germane to the City of Flagstaff public works and police departments).
Develop an understanding of the ideal strategies available to adapt to the aforementioned climate change impacts, the information necessary to implement those strategies, and metrics to measure their success (ostensibly improving resilience).
Identify, in general, the information and tasks Flagstaff will likely need to plan and implement these strategies. This information will be incorporated into subsequent workshops with the City of Flagstaff.

Tracking drought blends science and art. No single definition of drought works for all circumstances, so people rely on drought indices to detect and measure droughts. But no single index works under all circumstances, either. That's why we need the Drought Monitor, a synthesis of multiple indices and impacts, that represents a consensus of federal and academic scientists. The product will be refined over time as find ways to make it better reflect the needs of decision-makers and others who use the information.
The data cutoff for Drought Monitor maps is Tuesday at 7 a.m. Eastern Time. The maps, which are based on analysis of the data, are released each Thursday at 8:30 a.m. Eastern Time.
The U.S. Drought Monitor is produced in partnership between the National Drought Mitigation Center at the University of Nebraska-Lincoln, the United States Department of Agriculture, and the National Oceanic and Atmospheric Administration. Map courtesy of NDMC-UNL.
The National Science Foundation (NSF) and NBC Learn (NBC News' educational arm) have teamed up to produce a new informative video series that examines the long-term health of one of America's most important resources: water.
As climate rapidly changes and population grows, providing a sufficient supply and quality of water will be a critical challenge to people everywhere. These videos aim to help advance public understanding of the effects human activity and climate variability have on water and its distribution system.
"Sustainability: Water," an original seven-part collection, consists of detailed stories explaining significant challenges to managing the water supply in selected regions and cities across the United States.
The series highlights research funded by NSF and looks at the lives of scientists who are hard at work on projects designed to help pave the way to a more sustainable future. Each video features an NSF-supported scientist from a diversity of fields, geographic locations and institutions explaining a specific challenge and how these challenges are affecting the water supply. Each episode is available cost-free to teachers, students and the public at NSF and NBCLearn.com websites.
"Most Americans take water for granted," said Roger Wakimoto, assistant director for NSF's Directorate for Geosciences. "We have occasional water restrictions, but for most of us, when we turn on the tap, water is there. This series with NBC Learn aims to help people become more conscious of the threats to our water supply and understand the steps that need to be taken to maintain it."
"Our new series with NSF is an excellent opportunity to raise awareness about the challenges to our environment," said Soraya Gage, general manager of NBC Learn. "By exploring the challenge of sustainable water, we hope to raise awareness and spur dialogue about managing the water system and conserving Earth's most precious resource."
This video uses animation, graphics, and video clips to illustrate and explain each of the "flow" and "storage" processes in the Hydrologic Cycle, more commonly known as the Water Cycle: precipitation, interception, runoff, infiltration, percolation, groundwater discharge, evaporation, transpiration, evapotranspiration, and condensation.
Baltimore, Maryland is a major city situated on the Chesapeake Bay- a sprawling 64,000 square mile watershed. Currently, the Chesapeake is facing an environmental crisis due to pollutants. Scientist Claire Welty of the University of Maryland-Baltimore County is monitoring the travel times of pollutants in the urban streams in and around Baltimore. Through her research, she hopes to gain an understanding of the urban water cycle, and how municipalities can better prevent pollutants from contaminating the greater watershed.
The Rocky Mountains supply water to more than 60 million homes in the West, but this crucial water shed is in peril due to a tiny insect called the mountain pine beetle. Scientists Reed Maxwell of Colorado School of Mines and John Stednick of Colorado State University have teamed up to study the impact of the mountain pine beetle on water quantity and quality in the area.
Snow melt from the snow pack in the Sierra Nevada mountain range provides drinking water to about 30% of California’s residents, irrigates key crops in the San Joaquin valley, and runs hydroelectric power plants that supply at least 15% of the state’s electricity. Scientists Martha Conklin and Tom Harmon of the University of California, Merced are conducting research at the Southern Sierra Critical Zone Observatory, using wireless sensor technology to more accurately measure snow pack and snow melt so that state water managers can make better decisions on how to allocate this precious resource.
Part of the earth's largest surface freshwater system, Lake Erie is a vital source of drinking water for 11 million people. Researchers Anna Michalak, Tom Bridgeman, and Pete Richards are studying how farming practices and severe weather can increase the amount of fertilizer-derived nutrients in the water, which diminishes water quality and threatens the lake's ecosystem and the public's health.
Farmers in Kansas and other states that sit atop the Ogallala aquifer – the largest freshwater aquifer in North America – are pumping out water for crop irrigation far faster than natural seepage of rainwater can replenish it. Scientist David Hyndman from Michigan State University is helping develop a plan to better manage this vital resource for sustainable farming.
The nearly 10 million people in the city and county of Los Angeles, California require a lot of water – most of which is imported snow melt from the Eastern Sierra Nevadas and Rocky Mountains, hundreds of miles away. UCLA researchers Stephanie Pincetl and Mark Gold are studying how Los Angeles can reduce its water imports and better capture, store and reuse water for a more sustainable water supply.

In conjunction with Arizona Project WET, the Water Sustainability Program, and UA’s Water Resources Research Center, DCDC hosted 35 teachers at the eighth annual workshop. The theme of this year’s workshop was, "Using Models to Simplify the Complex Interactions of Water in the Valley."
Educators joined us to enhance their knowledge about how scientists and engineers develop and use models to solve problems and ask questions about water in the city. After completing this workshop educators understood how:
models are used to explain phenomena, analyze systems, and solve problems
Science and Public Policy, published by Oxford Journals, is a leading international journal on public policies for science, technology and innovation. It covers all types of science and technology in both developed and developing countries.

The connection between scientific knowledge and environmental policy is enhanced through boundary organizations and objects that are perceived to be credible, salient, and legitimate. In this study, water resource decision makers evaluated the knowledge embedded in WaterSim, an interactive simulation model of water supply and demand presented in an immersive decision theater. Content analysis of individual responses demonstrated that stakeholders were fairly critical of the model’s validity, relevance, and bias. Differing perspectives reveal tradeoffs in achieving credible, salient, and legitimate boundary objects, along with the need for iterative processes that engage them in the co-production of knowledge and action.

User engagement, stakeholder involvement, and public consultation in sustainability research have received increased attention over the last decade. Key driving factors behind this are that social outcomes, policy relevance, and user engagement have all become requirements for securing research funding. Many articles have provided compelling arguments for the need to reconsider why, when and how users are engaged within the research process. We propose a typology of user engagement strategies in research, focusing on the actual research process and emphasizing types of engagement in research. We illustrate these types with a comparative analysis of empirical examples from three interactive sustainability research projects, based in Canada and Switzerland. The article discusses the challenges that require a reconfiguration of institutional and organizational structures to seize the full potential of interactive sustainability research.
BEIJING — China is pushing ahead with a sweeping plan to move 250 million rural residents into newly constructed towns and cities over the next dozen years — a transformative event that could set off a new wave of growth or saddle the country with problems for generations to come.
The government, often by fiat, is replacing small rural homes with high-rises, paving over vast swaths of farmland and drastically altering the lives of rural dwellers. So large is the scale that the number of brand-new Chinese city dwellers will approach the total urban population of the United States — in a country already bursting with megacities.
This will decisively change the character of China, where the Communist Party insisted for decades that most peasants, even those working in cities, remain tied to their tiny plots of land to ensure political and economic stability. Now, the party has shifted priorities, mainly to find a new source of growth for a slowing economy that depends increasingly on a consuming class of city dwellers.
The shift is occurring so quickly, and the potential costs are so high, that some fear rural China is once again the site of radical social engineering. Over the past decades, the Communist Party has flip-flopped on peasants’ rights to use land: giving small plots to farm during 1950s land reform, collectivizing a few years later, restoring rights at the start of the reform era and now trying to obliterate small landholders.
Across China, bulldozers are leveling villages that date to long-ago dynasties. Towers now sprout skyward from dusty plains and verdant hillsides. New urban schools and hospitals offer modern services, but often at the expense of the torn-down temples and open-air theaters of the countryside.
"It’s a new world for us in the city," said Tian Wei, 43, a former wheat farmer in the northern province of Hebei, who now works as a night watchman at a factory. "All my life I’ve worked with my hands in the fields; do I have the educational level to keep up with the city people?"
China has long been home to both some of the world’s tiniest villages and its most congested, polluted examples of urban sprawl. The ultimate goal of the government’s modernization plan is to fully integrate 70 percent of the country’s population, or roughly 900 million people, into city living by 2025. Currently, only half that number are.
The building frenzy is on display in places like Liaocheng, which grew up as an entrepôt for local wheat farmers in the North China Plain. It is now ringed by scores of 20-story towers housing now-landless farmers who have been thrust into city life. Many are giddy at their new lives — they received the apartments free, plus tens of thousands of dollars for their land — but others are uncertain about what they will do when the money runs out.
Aggressive state spending is planned on new roads, hospitals, schools, community centers — which could cost upward of $600 billion a year, according to economists’ estimates. In addition, vast sums will be needed to pay for the education, health care and pensions of the ex-farmers.
While the economic fortunes of many have improved in the mass move to cities, unemployment and other social woes have also followed the enormous dislocation. Some young people feel lucky to have jobs that pay survival wages of about $150 a month; others wile away their days in pool halls and video-game arcades.
Top-down efforts to quickly transform entire societies have often come to grief, and urbanization has already proven one of the most wrenching changes in China’s 35 years of economic transition. Land disputes account for thousands of protests each year, including dozens of cases in recent years in which people have set themselves aflame rather than relocate.
This case study applies the theoretical concepts of frame and framing processes to identify and describe the diagnostic and prognostic frames for water sustainability expressed through an environmental decision support system. The research examines the development of WaterSim, a computer simulation model of water supply and demand in central Arizona. Qualitative data were generated through semistructured individual and group interviews, participant observations, and document analysis. The analysis identified a diagnostic frame defining the water sustainability problem as uncertain and long-term water supply shortage caused by prolonged drought, climate change impacts, and population growth. The prognostic frame for water sustainability defined the solutions to be urban residential water demand management, retirement of agricultural lands, and conversion of agricultural water to municipal uses to achieve safe yield of groundwater. The results of the study are discussed in terms of implications for decision support systems (DSS) design.
On June 10, 2013, Dave White, DCDC co-director and Senior Sustainability Scientist with the Global Institute of Sustainability and an ASU contingent, had the unique opportunity to travel to Tec de Monterrey in Monterrey, Mexico to participate in an exchange program focused on sustainability education.
Dave presented the sustainability research, education, and community and institutional outreach efforts conducted by DCDC with an emphasis on two key aspects.
First, the ongoing research and stakeholder outreach project which involves faculty researchers from both ASU and Tec. This project, informally called the Water Innovation Consortium, involves stakeholder engagement, social science, hydrology, and integrated decision support and was funded by the two universities along with Inter-American Development Bank and FEMSA Foundation.
Second, Dave also met with colleagues from Tec taking the opportunity to learn about their approach to sustainability education with the aim of improving our related efforts at ASU.
Dave met with specific faculty partners including Dr. Jurgen Malknecht, Director, Water Center for Latin America and the Caribbean(CAALCA), Tec de Monterrey.
