DCDC II will launch its new website in Fall 2011.
Since 2004, DCDC has served as one of five research projects funded by the National Science Foundation's Decision Making Under Uncertainty initiative. DCDC research, outreach and educational activities have focused on water management decisions in central Arizona in the context of the area's rapid population growth and urbanization, complex political and economic systems, variable desert climate, and the specter of global climate change. Although DCDC has been a regional case study, its research products and decision-support tools can be generalized to rapidly growing desert regions worldwide.
Over the six years of its first phase, DCDC has emerged as a "boundary organization," working at the interface of science and policy, coproducing new knowledge in partnership with the water management community. Through WaterSim, DCDC's simulation and decision tool, and extensive scientific research, it has developed "what if" scenarios of the future, using them to explore the potential, even likely, consequences of today's decisions. Engaging with stakeholders in the government, industry and the public, it has explored key questions, applying the best available scientific and institutional knowledge, and collaborating closely with water managers and policymakers to answer them. During its run, DCDC I produced nearly 200 publications, including five books, 50 book chapters and 138 journal articles.
Now in its second phase, DCDC II continues, expands and refines this mission, applying lessons learned and building upon the foundations laid to generate new knowledge about urban-system dynamics and decision-making in the face of long-term environmental risk. By improving adaptation and planning strategies, based on the best available social science understanding of individual motivations and societal norms, it will be possible for cities to become less climate-sensitive. In the process, DCDC II will also help to produce the next generation of researchers, transdisciplinary scholars that can move easily between the worlds of science and policy.
The Decision Center for a Desert City has created WaterSim on the Web, an interactive tool that brings science to the general public. It allows you to explore future water scenarios for metropolitan Phoenix in an easy-to-understand format. With WaterSim at your command, you can gauge water availability in response to changes in climate conditions, drought, population growth, urbanization, land use, and technological innovation, as well as test policy decisions about the built environment, landscaping practices, and recycled water.
Using WaterSim Explorer, users move decision-input levers and instantly view potential outcomes. Using WaterSim Scenario Builder, you can compare, side-by-side, two different scenarios. These features, along with the historical and geographical background provided, make WaterSim a powerful instructional and informational resource.
DCDC II is an interdisciplinary research center advancing knowledge, education, and community outreach for urban climate adaptation. Within the Center's activities:
Research, learning and outreach are synergistic activities that feed upon and reinforcing one another.
Discovery occurs at the intersection of basic and applied research where new strategies are found to address real‐world societal problems.
New data collection and analysis is adequately mixed with synthetic discoveries based on integrating existing data, models, and knowledge.
Problem solving is adaptive and reflexive, building upon past experiences and lessons learned in other centers engaged in the newly evolving field urban climate adaptation.
Emphasis is placed on feedbacks and nonlinearities that produce unintended consequences and reveal hidden vulnerabilities in complex urban resource systems.
Scenarios, simulation modeling, and principles of decision making under uncertainty build capacity to anticipate the future.
Develop new understandings of how complex urban systems will function in a changing climate.
Translate climate modeling and research into tools for managing complex urban systems in the face of climate change and other environmental risks.
Build a boundary organization in which science is informed by and informs policy and decision making.
Develop and implement learning opportunities at the boundary of science and policy for students interested in urban climate adaptation.
Communicate the need for urban climate adaptation to decision makers and larger public audiences.
Some people and places are at greater risk than others in the face of climate change, rapid growth, and institutional factors. DCDC examines vulnerability to water shortage in Greater Phoenix and in the upland watersheds upon which it depends for water. Researchers investigate the physical, social, and institutional factors that put people and their communities at risk, how aware they are of relevant risk, and what actions are most effective in mitigating risk.
DCDC uses a complex integrative model to anticipate the effects of climate conditions, rapid growth, and policy decisions on future water supply and demand conditions in Phoenix. The model, dubbed WaterSim, is shown in the Decision Theater where regional water managers and other decision makers can experiment with and discuss the model, and where DCDC social scientists can investigate the water decision making process. WaterSim on the Web also is available online, along with a body supporting information to help users understand what they are seeing.
DCDC is engaged in water education at a variety of levels, ranging from K-12 to graduate education. Activities include water education workshops for water providers and teachers and the development of new classroom materials such as learning modules, an online atlas, and WaterSim on the Web. DCDC offers research experiences and internships for undergraduates and seminar classes in decision making under uncertainty for graduate students.
DCDC seeks a more complete understanding of the local and regional climate conditions that influence Phoenix's water supply and demand. Studies include efforts to improve drought prediction, downscale general circulation models to the watersheds upon which Phoenix depends for its water, estimate the uncertainty in runoff associated with climate change models, represent the urban heat island and predict its characteristics with future growth, and evaluate the effects of the urban heat island on water use.
DCDC studies the factors influencing water demand and how different policies, attitudes, and behaviors might mitigate the increasing demand for water in Phoenix. Projects include small-area water demand forecasting, analyses of the future effects of water conservation policies on residential water use, studies of the values and objectives of water stakeholders, and studies of the way environmental values structure people's water use and conservation attitudes.
DCDC operates at the boundary of science and policy and investigates ways to more easily cross that boundary. Researchers interact on a regular basis with the regional water community and consider their views in the development of WaterSim and project management. In addition, several researchers are studying how decision makers view and engage with scientific products and how the social networks of scientists and policy makers evolve with participation in DCDC.
