The Decision Center for a Desert City at Arizona State University—funded by the National Science Foundation since 2004—conducts research relevant to water resources and urban climate dynamics under multiple uncertainties. This report summarizes and synthesizes research findings and achievements of DCDC after almost a decade of research and science-policy interactions. Water resource decision-making is complicated by climate change and variability, population growth and economic development, diverse stakeholder interests and fragmented governance. While these factors generate various uncertainties and complexities for decision-makers, DCDC pursues research to create a more sustainable future. The DCDC contributes to water management and urban sustainability by conducting basic science and collaborating with policymakers and stakeholders to solve real-world problems. As detailed herein, DCDC research, education, and community outreach have made substantial contributions to improving water-resource governance and climate adaptation.

DCDC II is focused on developing, implementing, and studying an integrated decision-support process for environmental decision making based on social science principles. Through an integrated approach to research and education, DCDC will train a new generation of scientists who can work successfully at the boundaries of science and policy, and produce innovative solutions to society’s pressing environmental challenges. To accomplish these goals, DCDC II will build a dynamic bridge between ASU and local policy communities and seek global solutions for urban climate adaptation. This plan articulates DCDC’s vision and mission, describes key tasks and outlines a process of evaluation based on both standard and innovative metrics.

Prior to developing and approving new ordinances that would further regulate sex- offender distance restrictions and clustering, the Phoenix City Council approved a study to examine the nature and impact of sex-offender clustering. Their overall goal was to use the study to fill in some important knowledge gaps about the issue of sex-offender residential clustering in order to inform the development of effective policy. To examine this issue on behalf of the city council, we relied on a multi-methodological research design. We wanted to incorporate information from several different points of view, giving policy makers a more comprehensive perspective from which to inform their decision making. For this study, we relied on four resources: official police data, offender interview data, citizen survey data, and key stakeholder interview data.

In 1993, the Arizona-Mexico Commission and its sister organization, the Comisión Sonora-Arizona, initiated a binational strategic economic planning process to analyze how the two neighboring states could increase their regional competitiveness in the world economy and enhance the overall quality of life for their residents. One of the recommendations of the Strategic Economic Development Vision was to develop a set of indicators as a tool to monitor progress toward the goals of binational economic development. The purpose of the Regional Economic Indicators is to help policy and decision-makers understand and monitor economic changes in the Arizona-Sonora region and to support policies that promote economic transformation, investment and entrepreneurship in the region.

The study reported here was designed to examine the impact of background meteorological conditions on the propagation of noise from urban freeways in the Phoenix area. The aim was to understand and predict how sound waves emanating from highways respond to the vertical profiles of atmospheric temperature gradients and velocity shear, so that sound measurements can be interpreted with regard to the environmental variability.
