March 5 Water/Climate Briefing
Arizona Water Supply Sustainability: In-state Water Transfers
Moving water from one area of Arizona to another has the potential to create controversies, especially if the area from which the water is being transferred has existing water uses and economies built on that water supply.
In the Arizona Department of Water Resources report, “Arizona’s Next Century: A Strategic Vision for Water Supply Sustainability”, it is suggested that in-state water transfers will play a strategic role in Arizona’s sustainable water future. Yet, the report suggests that a comprehensive analysis of water transfers is needed to better understand their role in our water future and their secondary benefits and impacts.
This Water/Climate Briefing will be held at the ASU Downtown Phoenix campus in the A. E. England Auditorium. RSVP today with Katie Peige!
Water Reuse in Central Arizona
DCDC co-director on KAET Ch 8 Arizona Horizon
Check out DCDC co-director, Dave White, tonight Tuesday, March 4, 2014 at 5:30pm on KAET Channel 8′s Arizona Horizon. Dave will speak with host Ted Simons about the Decision Center for a Desert City’s recently released technical report, Water Reuse in Central Arizona.
Authored by Ariane Middel, Ray Quay, and Dave White, the report explores issues critical to water reuse, along with challenges and opportunities for the future. This report attempts to inform policy conversations around wastewater use in Arizona.
Covering topics including existing and projected wastewater supply and demand, potential for increased competition and costs, the role of public perceptions, and industrial perspectives, the report highlights issues vital to the water sustainability of Arizona and presents a framework to address public policy issues.

Water management decision makers’ evaluations of uncertainty in a decision support system: the case of WaterSim in the Decision Theater
Authors: Dave White, Amber Wutich, Kelli Larson, and Tim Lant
Model-based decision support systems are increasingly used to link knowledge to action for environmental decision making. How stakeholders perceive uncertainty in models and visualisations affects their perceptions of credibility, relevance and usability of these tools.
This paper presents a case study of water decision makers’ evaluations of WaterSim, a dynamic water simulation model presented in an immersive decision theatre environment.
Results reveal that decision makers’ understandings of uncertainty in their evaluations of decision support systems reflect both scientific and political discourse. We conclude with recommendations for design and evaluation of decision support systems that incorporate decision makers’ views.
