Sustainability scientist Deepak Chhabra, a professor in the School of Community Resources and Development, led a study commissioned by the Maricopa County Parks and Recreation Department to demonstrate how investment in public parks provides an economic return.
Using survey data from park visitors to eight iconic parks – six in Maricopa County and two that span into Pinal and Yavapai counties – the team ran impact studies for each park, as well as an aggregate study on the Phoenix metropolitan area. For every dollar invested by Maricopa County parks, Chhabra and her team found approximately $1.40 was generated, after costs.
Chhabra noted that although individual park returns varied, it is difficult to determine why; the size of the park and amenities offered differ and could factor in. This provides feedback to the parks on how they might improve their individual results.

The Arizona Extreme Weather, Climate and Health Profile Report – a document produced by a team of ASU researchers and the Arizona Department of Health Services in March 2015 – is now available to the public.
In an effort to provide local health officials with a mechanism for addressing climate-related public health impacts, and to support the creation of regional public health adaptation and mitigation efforts, the U.S. Centers for Disease Control and Prevention developed the Building Resilience Against Climate Effects framework.
This report addresses the first step in the framework, which is focusing on climate-related hazards and associated health impacts of major importance to Arizona – namely, extreme heat and air pollution. It also summarizes historic temperature and precipitation trends, and provides projections for the future.
Among the report’s authors are sustainability scientists Nalini Chhetri, David Hondula, Ariane Middel and Nancy Selover, as well as Alex Karner – a postdoctoral research fellow with the Rob and Melani Walton Sustainability Solutions Initiatives.

More than 60 law professors from around the country convened at the conference for panels on issues such as climate-change policy, natural-resources law, agricultural and food regulation, and disaster law. By assembling many of the nation’s preeminent legal scholars in these fields, the conference – hosted by the Program on Law and Sustainability at ASU’s Sandra Day O’Connor College of Law – seeks to spur new research ideas and collaborations.
“Sustainability-related policy innovation is occurring at a rapid pace throughout the country, but there are limited opportunities for legal scholars researching in this area to come together and share ideas,” said sustainability scientist Troy Rule, who serves as faculty director of the Program on Law and Sustainability. “This conference will help to fill this gap.”

On June 6, World Wide Views invites participants from around the world to share their perspectives on climate change and energy. The one-day event rolls out in time zones around the world, with more than 5,000 citizens and 50 countries participating. The views that are shared will be incorporated into the United Nations Framework Convention on Climate Change in Paris this December.
“We want to honor the multiple views about climate and energy because the policy or outcome of this UN framework should be useful for everybody,” says Netra Chhetri, a senior sustainability scientist and a WWViews project director. “Even if someone hasn’t finished high school, he or she is still a citizen of this particular geography. They have their views, and they may be different than those embraced by the educated community, but that doesn’t mean those views should be neglected.”

At the April 14 President’s Recognition Reception, ASU President Michael M. Crow awarded university movers and shakers with the President’s Award for Innovation, the President’s Award for Sustainability and the President’s Medal for Social Embeddedness, as well as the SUN Awards for Individual Excellence.
Recipients of the President’s Award for Sustainability included the Seville Orange Juicing Partnership, a venture among ASU Facilities Management Grounds Services, Aramark, Campus Harvest and local Sun Orchard Juicery. This past year, volunteers and Facilities Management Grounds staff harvested 10,000 pounds of Seville oranges from the Tempe campus, and Sun Orchard processed and bottled 380 gallons of juice. Aramark then purchases the juice for their chefs to use in residence halls, restaurants and at catered events. Even the orange peel is processed and used by local farmers as a healthy, all-natural feed for cattle and hogs.
The Clinton Global Initiatives’ University Zero Waste and Biodesign’s Sustainability Science Education Project also received the President’s Award for Sustainability.

The Julie Ann Wrigley Global Institute of Sustainability is now equipped with a system capable of achieving zero waste, defined as 90 percent diversion from landfills. The system offers the option of recycling, composting, TerraCycling, plastic film and bag recycling, and landfilling “waste” – a term now nullified as all materials diverted from the landfill are valuable resources.
This seemingly complex five-option system is viewed as standard in many countries around the world, including Germany and Japan.
The opportunity to practice what is preached at the sustainability headquarters of ASU requires students, staff and faculty to learn how to properly use the zero waste system. In order for Wrigley Hall inhabitants and visitors to see these bins as empowering rather than overwhelming, graduate student zero waste advocates held a Zero Waste Kick-Off Party on April 9. The celebration on the first floor of Wrigley Hall helped to raise awareness about the new zero waste pilot, eliminate myths about “waste” and educate on proper diversion practices.

By the time we reach adulthood, most Americans have come to understand that money doesn’t grow on trees. But a new study published in PLOS ONE this month shows that trees do – figuratively speaking – grow on money.
Christopher Boone, dean of the School of Sustainability at Arizona State University, was among the authors of the study. The article resulted from a workshop led by Boone at the National Center for Ecological Analysis and Synthesis.
“We studied seven cities across the U.S.,” says Boone. “What we found was a correlation between low-income neighborhoods and low-density tree cover.”

A study led by ASU sustainability scientist Arianne Cease demonstrates how human food production can have a profound impact on ecosystems.
For example, phosphorous is commonly added to foods as a preservative, leading to an excess in waste streams. It can also run off and enter the water supply when waste is used as fertilizer in agriculture. When there is an imbalance of nutrients like phosphorous entering bodies of water, toxic algal blooms may result.
“These algal blooms can contaminate drinking water and reduce water clarity, oxygen levels and biodiversity,” said Michelle McCrackin, a researcher at Stockholm University (Sweden) and a member of Cease’s team.
Cease’s study shows that new ways of recycling nutrients to fertilize crops, along with upgrades to waste treatment facilities to remove more nutrients like phosphorus, could substantially reduce water pollution.

A new study led by sustainability scientist Matei Georgescu reveals some of the dynamics at play as one region of the country, the Central Valley of California, braces for substantial population growth and all it entails. The study, based on computer simulations of rural to urban land conversion, shows that as areas of California grow and develop, the resulting built environment could generate additional heat.
Georgescu used ensemble-based simulations employing EPA projections of urban growth to assess urban expansion climate effects by the year 2100 in the Central Valley. He first assessed the resulting rise in regional temperatures and then explored several temperature mitigating strategies for buildings: cool roofs, green roofs and hybrid approaches. He found that as the state deploys temperature-mitigating technologies, there are secondary effects that appear to take place, such as less daytime air turbulence, which could lead to higher concentrations of pollutants.
But the urban heat island effect can be mitigated using new technologies and the latest in sustainable design techniques, said Georgescu, whose “Challenges associated with adaptation to future urban expansion” appears in the April 1 issue of the Journal of Climate. Finding the right combinations of technologies and techniques will be key.

Arizona State University computer scientist Carole-Jean Wu is gaining attention for her work to improve the energy efficiency of both large- and small-scale computing nodes, encompassing everything from desktop processors, smartphones and other mobile devices to business-scale data centers.
Wu’s research focuses on designs for chip-multiprocessors and heterogeneous computing systems, energy-efficient smartphone architecture and architectural energy harvesting techniques for modern computing nodes. Rather than allowing superfluous heat generated by devices to reduce performance speed, Wu decided to harvest it with a thermoelectric generator, which converts heat to electricity using a phenomenon called the Seebeck effect.
Wu’s paper, “Architectural Thermal Energy Harvesting Opportunities for Sustainable Computing,” recently received the Best of Computer Architecture Letters (CAL) award.

The story goes that when beetles were discovered in the eaves of the great hall at New College in Oxford, everyone began wondering where they could possibly find replacements for the gigantic timbers that had held up the roof for hundreds of years. They needed oak trees almost as old as the building itself. As it turned out the founders of the college had planted oaks expressly for the purpose of repairing structures, with university foresters protecting them over generations. The great hall was completed in the late 1300s, and they were building something that they intended to last functionally forever.
Today it seems like the expected lifespan of a building is getting shorter, not longer. More alarmingly, our perception of time seems to be narrowing—we forget our history just as readily as we ignore the future.

Using a three-year $600,000 grant from the Water Sustainability and Climate program, ASU engineers and sustainability scientists Mikhail Chester and Thomas Seager are leading a project that will provide a guide to boosting the resilience of infrastructure systems against potential threats posed by climatic changes.
Seager will work on developing one of the key methods the project team hopes will encourage foresight in policymaking and planning for these infrastructure networks. Using Arizona as a case study, Seager will devise a game-based learning platform – specifically a computer game – to educate leaders about possible future infrastructure vulnerability issues and how to approach the task of assessing what can be done to deal with them sooner rather than later.
The work based at ASU’s Sustainable Urban Systems Lab, which is directed by Chester, will focus primarily on desert regions because they are especially vulnerable to environmental impacts brought on by climate-related factors.

In the latest installment of the “Sustainable Cities” series, Senior Sustainability Scientist Nancy Grimm discusses common misconceptions about ecologists and nature. She presents the idea of untouched wilderness as an example.
“We’ve recognized that there really aren’t such places, or are very few such places, left on Earth,” says Grimm, an ecologist herself who has worked in the field for more than 30 years.
Grimm is also the director of Central Arizona-Phoenix Long-Term Ecological Research, a project launched in 1997. CAP LTER is one of 26 LTER sites throughout the United States. Based at ASU, it is one of only two sites that examine urban ecosystems. Specifically, the Phoenix site answers questions about ecosystem services – benefits provided to people by the environment or wildlife – and studies how humans interact with nature in their cities.
