Water/Climate Briefings

DCDC hosts Water/Climate Briefings on a regular basis. These briefings are a regular forum for the water-policy community, DCDC researchers, and students to exchange knowledge and ideas. The typical format is a panel of experts and community partners discussing issues such as the urban heat island, water re-use, and the energy-water nexus, followed by audience participation and questions. Since the launch of DCDC, we have hosted four to seven briefings each year, with panelists representing the scientific and professional perspectives.

2018-2019 Water/Climate Briefings

December 5, 2018 – Innovative Stormwater Management: Resilience for Extreme Weather

Panelists

  • Harry Cooper, Landscape architecture and Water Conservation Branch Manager, Flood Control District of Maricopa County
  • Maggie Messerschmidt, Urban Conservation Program Manager, The Nature Conservancy
  • David Sampson, Research Scientist, Decision Center for a Desert City, ASU
  • Ray Quay, Moderator and Director of Stakeholder Relations, Decision Center for a Desert City, ASU

Traditionally, urban water utilities built and maintained “gray infrastructure” to manage stormwater. These facilities were designed to safely collect and remove stormwater runoff from city buildings, streets, and parking lots. However, recent extreme weather events suggest that storms are becoming more extreme and these structures may no longer be fail-safe. Stormwater is also now being viewed not as a hazard to be removed, but a resource that can be used as a water supply.

A new stormwater management paradigm is now emerging. Practitioners and researchers are designing and testing “green” stormwater infrastructure as small scale, street-level alternatives for diverting and even collecting stormwater, often for beneficial use.

Guests joined us for an interactive discussion on the efforts to transition urban areas to new solutions for managing stormwater as a beneficial use within the urban environment while maintaining flood resilience.

September 17, 2018 – Resilient water: Adapting to drought and shortage in Phoenix and Denver

Panelists

  • Jim Lochhead, CEO/Manager, Denver Water
  • Kathryn Sorensen, Director, City of Phoenix Water Services Department
  • Dave D. White, Professor, School of Community Resources and Development, ASU
  • Wellington “Duke” Reiter, Special Advisor to President Crow, ASU

The Colorado River is essential to the social, environmental, and economic sustainability of the American West.

In cities like Phoenix, Denver, and Las Vegas, the Colorado River contributes to the water supplies of more than 1 in 10 Americans.

After nearly two decades of drought in the West and growing concern over climate change impacts, an official declaration of shortage on the Colorado River is a real and growing possibility.

These challenges also present windows of opportunity for communities to develop innovative solutions to ensure resilient and sustainable water supplies.

During this Water/Climate Briefing, leading urban water managers and researchers will discuss how they have anticipated this challenge and have developed plans to adapt to drought, climate change, and to ensure safe, resilient, and reliable water supplies for their communities.

August 21, 2018 – Building Resilience for Uncertain Water Futures

Panelists

  • Patricia Gober, Research Professor, School of Geographical Sciences and Urban Planning
  • Dave D. White, Moderator and Director, Decision Center for a Desert City, ASU

Geographer Patricia Gober, the founding co-director of the Decision Center for Desert City, launches this year’s Water/Climate Briefings with a conversation about her newly released book, Building Resilience for Uncertain Water Futures. Gober will describe the existential threats facing global water systems: population growth and economic development, unsustainable use, environmental change, and weak and fragmented governance. Because today’s water systems are increasingly complex and face greater uncertainty in the future, a “business-as-usual” approach to water science and management are not enough. Instead, a more holistic, strategic, agile, and publicly engaged process of water decision making is needed.

Gober’s research centers on climate adaptation, water-resources management, and the use of science and visualization for real-world decision-making. Gober, a fellow of the American Association for the Advancement of Science, was awarded the Prince Sultan Abdulaziz International Price for Water in 2008.

Planning for sustainable water management involves working with a wide network of complex social and natural adaptive systems.

This network intersects around both supply and demand and a key aspect of sustainability is institutional resilience to keep supply and demand balanced over the long-term.

Understanding the dynamics of demand is essential for adapting to changes that occur in this systems network.

This briefing reviewed current water management practices and ASU research that focus on the dynamics and driving forces of water demand within communities utilizing water from the Colorado River Basin.

Relationships between water demand, urban growth trends, and water management policies of different communities were explored.


2016-2017 Water/Climate Briefings

Drought and Water Shortage: Global Challenges and Solutions

March 15, 2017 – Water Governance in Pernambuco, Brazil

Panelists

  • Pedro Coli, Analyst, Integrated Water Resources Management, Inter-American Development Bank
  • Giuseppe Mascaro, Assistant Professor, School of Sustainable Engineering and the Built Environment, ASU
  • Dave D. White, Professor, School of Community Resources and Development and Director, Decision Center for a Desert City, ASU

Our panelists join us from three of the major megacities of the developing world: Johannesburg, South Africa, São Paulo, Brazil, and Delhi, India. As they engage in cross-comparative analysis and share their experiences, what lessons can communities in the Colorado River Basin take away from these discussions?

The panelists will draw connections between the structure and pattern of urban growth – particularly, in informal settlements – and the challenges of water governance. They will also examine new risks and vulnerabilities associated with rapid urbanization and discuss how these are likely to be exacerbated by climate change. In addition, the panelists will pinpoint emerging conflicts and evaluate attempts to address them through formal and informal institutions, legal structures, and policy while exploring cross-comparative lessons, particularly innovative approaches to infrastructure design, citizen participation, and social learning.


September 1, 2016 – Streaming Ahead: Unpacking Australia’s Urban Water Transition

Keynote Speaker

Megan Farrelly, PhD
Senior Lecturer, School of Social Sciences, Monash University, Australia
Project Leader CR Water Sensitive Cities Monash Water for Liveability
Chair, International Working Group for Water Sensitive Urban Design

Confronted with rapidly growing populations, increasing climate stress, and uncertain supplies of natural resources, the liveability of urban environs is seriously challenged.

Conventional, centralised, technical infrastructure systems, such as urban water and energy, are increasingly ill-equipped to meet these challenges, or to build the resilience that will safeguard our urban spaces as multifunctional, socio-cultural, and aesthetic spaces affording people safe and healthy lifestyles. Building such resilience requires a fundamental shift in environmental governance practices, which raises a core question: How can we best support this change? An emerging response lies in the view we can actively steer or facilitate a sustainability transition.

Dr. Farrelly will showcase contemporary Australian urban water practices and unpack the key socio-institutional ingredients that have helped guide this shift in practice.

A particular focus will be on how the city of Melbourne has become regarded as a front runner for advancing alternative urban water practices.


2015-2016 Water/Climate Briefings

Exploring our New NSF Award Research Themes

In summer 2015, DCDC was awarded a renewal from the National Science Foundation that effectively launches the next wave of our research, education and community outreach. Thanks to this new $4.5 million investment, DCDC will expand on the last decade of scholarship on water sustainability and climate adaptation beyond Phoenix to include other cities dependent on water from the Colorado River Basin. DCDC III will explore transformational solutions for urban water sustainability transitions necessary to sustain water supplies through the current drought and beyond. This research will be conducted through four integrated project areas.

April 27, 2016 – Sustainability Transitions for Urban Water Systems in the Colorado River Basin

Panelists

  • Arnim Wiek, IPA 4 Co-Lead, Associate Professor, School of Sustainability
  • Michael Schoon, IPA 4 Co-Lead, Assistant Professor, School of Sustainability
  • Marilyn DeRosa, Deputy Public Works, Director, City of Tempe Water Utilities
  • Kevin Moran, Senior Director, Water Program, Environmental Defense Fund
  • Dave White, Moderator and Director, Decision Center for a Desert City

The Decision Center for a Desert City (DCDC) at ASU is entering its third phase of use-inspired sustainability science on decision making under climatic, biophysical, and societal uncertainties. DCDC III research will be carried out in four Integrated Project Areas (IPA). In this briefing, the panel will discuss sustainable transformational strategies, the subject matter of IPA 4.

The goal of IPA 4 is to develop a theoretically informed understanding of sustainability transitions for urban water systems in the Colorado River Basin and to enhance the capacity of cities to develop, implement, and evaluate transformational water solutions. This will be accomplished through a review of existing water solutions, modeling simulations, and real-world transition experiments.

The panel will explore solution options for reducing the potential water deficit in the Colorado River Basin and moving towards a sustainable water future in the region. Topics include: the need for transformational solutions; how we can learn about solutions through pilot projects and evaluation; the advantage of integrated solutions and broader sustainability outcomes; the role of modeling simulations in developing and testing pilot project ideas; and an approach for transferring and scaling-up solutions.


March 3, 2016 – DCDC Annual Keynote: A Conversation about Solutions for Water Sustainability in the Colorado River Basin

Panelists

  • Tom Buschatzke, Director, Arizona Department of Water Resources
  • James Eklund, Director, Colorado Water Conservation Board
  • Wellington “Duke” Reiter, Moderator and Special Advisor on Urban Initiatives, Office of the President, ASU

The Colorado River and its tributaries provide a range of ecosystem services, contributing to municipal water supplies for nearly 40 million people in seven western states, irrigating millions of acres of farmland, generating thousands of megawatts of electrical capacity for the region, and providing critical habitat for threatened and endangered species.

While the region has thus far avoided an official declaration of water shortage on the Colorado River, significant challenges remain. Together, the states of the Colorado River Basin are developing strategies to address issues including drought, groundwater management, climate variability, and infrastructure needs. So the question remains: can an over-allocated Colorado River Basin achieve water sustainability?

Policy leaders from Arizona and Colorado will discuss this question as they explore existing and possible future innovative and collaborative solutions to water sustainability that will ensure continued social, economic, and environmental vitality for the West.
