We investigated the spatial and temporal variation in June mean minimum temperatures for weather stations in and around metropolitan Phoenix, USA, for the period 1990 to 2004. Temperature was related to synoptic conditions, location in urban development zones (DZs), and the pace of housing construction in a 1 km buffer around fixed-point temperature stations. June is typically clear and calm, and dominated by a dry, tropical air mass with little change in minimum temperature from day to day. However, a dry, moderate weather type accounted for a large portion of the inter-annual variability in mean monthly minimum temperature. Significant temperature variation was explained by surface effects captured by the type of urban DZ, which ranged from urban core and infill sites, to desert and agricultural fringe locations, to exurban. An overall spatial urban effect, derived from the June monthly mean minimum temperature, is in the order of 2 to 4 K. The cumulative housing build-up around weather sites in the region was significant and resulted in average increases of 1.4 K per 1000 home completions, with a standard error of 0.4 K. Overall, minimum temperatures were spatially and temporally accounted for by variations in weather type, type of urban DZ (higher in core and infill), and the number of home completions over the period. Results compare favorably with the magnitude of heating by residential development cited by researchers using differing methodologies in other urban areas.

Latinas may be unlikely to report violent crime, particularly when undocumented. This research examines the impact of fear of deportation and trust in the procedural fairness of the justice system on willingness to report violent crime victimization among a sample of Latinas (N = 1,049) in the United States. Fear of deportation was a significant predictor of Latinas perceptions of the procedural fairness of the criminal justice system. However, trust in the police is more important than fear of deportation in Latinas’ willingness to report violent crime victimization. Social workers can provide rights-based education and encourage relationship building between police and Latino communities.

City governments are increasingly interested in the concept of urban resilience. While theoretical debates continue to develop and critique the value of ‘urban resilience,’ a growing number of cities are organizing policies and projects around the concept. Building urban resilience is viewed as a key concern for cities facing, in particular, climatic threats –although other urban challenges and equity concerns are increasingly prioritized. Support from city leadership and large funding opportunities, such as the Rockefeller Foundation’s 100 Resilient Cities program, have encouraged some leading cities to create and manage city-wide resilience strategies. Yet pioneering cities have few guideposts to institutionalize resilience. This research evolved out of conversations with city officials in Portland, OR who were interested to learn how other cities were organizing resilience work. We explore how urban resilience is being structured and coordinated in 19 North American cities, focusing on emerging definitions, organizational structures, internal and external coordination efforts, and practitioners’ insights. We situate our findings on emerging governance approaches and lessons learned within the current urban resilience literature on governance by reviewing 40 academic papers and identifying 6 recurrent factors for effective governance. Additionally, we conducted 19 semi-structured interviews with North American resilience practitioners to describe emerging organization trends and share lessons from practice. Based off our interviews, we propose 5 key findings for structuring resilience work in cities effectively. These include: establishing a clear, contextual definition and scope, bringing communities into the process, championing the agreed-upon vision, balancing a centralized and dispersed approach, and recognizing tradeoffs in organizational placement. This research provides practitioners with insights to help facilitate resilience work within their cities and contributed to the scholarly debate on moving resilience theory toward implementation.

This report describes the process by which I created a concise but comprehensive online source of information about best practices in sustainability for urban planners. The goal of the project was to provide accessible information that would help planners in ways that help them comprehend and implement sustainable solutions to common planning problems that are found throughout the United States. To create the website, I researched methods for communicating clearly to planners, took a graduate course in communicating about sustainability, and drew on information that I had compiled on sustainable solutions for transportation, economy, water, green space, and governance.

Cities are developing innovative strategies to combat climate change but there remains little knowledge of the winners and losers from climate-adaptive land use planning and design. We examine the distribution of health benefits associated with land use policies designed to increase vegetation and surface reflectivity in three US metropolitan areas: Atlanta, GA, Philadelphia, PA, and Phoenix, AZ. Projections of population and land cover at the census tract scale were combined with climate models for the year 2050 at 4 km × 4 km resolution to produce future summer temperatures which were input into a comparative risk assessment framework for the temperature-mortality relationship. The findings suggest disparities in the effectiveness of urban heat management strategies by age, income, and race. We conclude that, to be most protective of human health, urban heat management must prioritize areas of greatest population vulnerability.

We use the Northeast US Urban Climate Archipelago as a case study to explore three key limitations of planning and policy initiatives to mitigate extreme urban heat. These limitations are: (1) a lack of understanding of spatial considerations—for example, how nearby urban areas interact, affecting, and being affected by, implementation of such policies; (2) an emphasis on air temperature reduction that neglects assessments of other important meteorological parameters, such as humidity, mixing heights, and urban wind fields; and (3) too narrow of a temporal focus—either time of day, season, or current vs. future climates. Additionally, the absence of a direct policy/planning linkage between heat mitigation goals and actual human health outcomes, in general, leads to solutions that only indirectly address the underlying problems. These issues are explored through several related atmospheric modeling case studies that reveal the complexities of designing effective urban heat mitigation strategies. We conclude with recommendations regarding how policy-makers can optimize the performance of their urban heat mitigation policies and programs. This optimization starts with a thorough understanding of the actual end-point goals of these policies, and concludes with the careful integration of scientific knowledge into the development of location-specific strategies that recognize and address the limitations discussed herein.
