A team of 10 UCLA professors has earned a $956,000 award for a project that will combine their expertise in engineering, urban planning, public health and environmental law to address the rapid increase in the number of extreme heat days in Los Angeles.

The prize is funded by a 2015 donation from the Anthony and Jeanne Pritzker Family Foundation.

The project, called Heat Resilient L.A., will over the next two years determine where and when people moving around the city are most vulnerable to the effects of extreme heat — a problem being caused by climate change — and assess which communities most need cooling interventions.

Based on their findings, the team will design new cooling structures and work with local stakeholders to determine where they should be installed. The team has designed a prototype structure that resembles a bus stop shelter, but in addition to a roof that provides shade, it also uses a combination of radiant and evaporative cooling technologies to provide “passive cooling” for those nearby.

Throughout the project, the researchers plan to engage directly with communities to produce the best possible design for the cooling structures and choose the best possible locations. Among the elements that helped the project stand out: its focus on equity and community engagement, and its use of devices other than shade and trees to provide cooling for local hot spots.

“What’s unique right now is that we have access to a portfolio of solutions and technologies that hadn’t been either thought of as plausible solutions or, frankly, available even just a few years ago,” said Aaswath Raman, a member of the Heat Resilient L.A. team and an assistant professor of materials science and engineering at the UCLA Samueli School of Engineering. Raman, who is designing the cooling structures using technology that has been developed in recent years at UCLA and elsewhere, said the project is an opportunity to explore the real-world use of emerging cooling technologies and materials.

That should not only help Los Angeles communities but also provide insights that he and others can use to continue building better technologies.

‘We wanted to bring together brilliant minds at UCLA who had never collaborated before, and push them to bring fresh ideas to the table.’ — Cassie Rauser, executive director of the UCLA Sustainable LA Grand Challenge

The winning project was chosen through a new UCLA initiative that upended the traditional model for conceiving and funding research projects. The program, called the Sustainable LA Grand Challenge Sandpit, emphasized connection, experimentation and blue-sky thinking.

In all, eight teams made up of more than 60 faculty members from 27 UCLA departments participated.

The program culminated in December with an online pitch event that worked more like the TV show “Shark Tank” than a typical call for proposals. Instead of preparing dense written submissions, the teams had to sell their research projects — all focused on sustainability — to a panel of jurors that included UCLA deans as well as chief sustainability officers from the city and county.

The Heat Resilient L.A. pitch was led by Raman; V. Kelly Turner, an assistant professor of urban planning at UCLA Luskin; and David Eisenman, a professor in residence at the David Geffen School of Medicine at UCLA and at the UCLA Fielding School of Public Health.

The other members of the winning team are Cara Horowitz, co-executive director of the UCLA Emmett Institute on Climate Change and the Environment; Sungtaek Ju, professor of mechanical and aerospace engineering, and of bioengineering; Travis Longcore, associate adjunct professor at the UCLA Institute of the Environment and Sustainability; Juan Matute, deputy director of the UCLA Institute of Transportation Studies; Gregory Pierce, associate director of the UCLA Luskin Center for Innovation; Kirsten Schwarz, associate professor of urban planning; and Walker Wells, lecturer in urban planning.

“The sandpit was definitely not business as usual, and that was the point,” said Cassie Rauser, executive director of the UCLA Sustainable LA Grand Challenge, a campuswide initiative to help transform Los Angeles into the world’s most sustainable megacity by 2050. “We wanted to bring together brilliant minds at UCLA who had never collaborated before, and push them to bring fresh ideas to the table. This type of interdisciplinary problem-solving is absolutely critical for addressing Los Angeles’ complex sustainability challenges.”

Competitors were invited to develop projects that directly address goals outlined in sustainability plans put forward by Los Angeles County and the city of Los Angeles, while paying particular attention to environmental justice and equity. The “sandpit” name was meant to encourage participants to bring a childlike sense of curiosity, openness and possibility into the process.

Teams and research concepts formed over the course of three months of online workshops designed to push participants out of their disciplinary bubbles and intellectual comfort zones — a critical aspect of the experience, according to Turner, who has studied what makes interdisciplinary collaborations work.

“So often it is about the informal interactions that get folks comfortable with being uncomfortable with each other, so that they can come up with the really innovative ideas,” she said.

The seven teams that did not win the grand prize will each receive $25,000 in seed funding from the Sustainable LA Grand Challenge, which will also provide continued research development support to help the teams further develop their ideas and pursue full funding from external organizations.

“One of the most exciting aspects of the sandpit is that we heard eight fantastic pitches,” said Eric Hoek, a UCLA professor of civil and environmental engineering and director of the Sustainable LA Grand Challenge. “Any of those projects could make a significant, tangible contribution toward our city’s and county’s sustainability goals, and we’re excited to help them all realize their potential.”

Park on Cumulative Effect of Heat on Learning

R. Jisung Park, associate director of economic research at the UCLA Luskin Center for Innovation, spoke to KJZZ’s The Show about his research into the link between hotter temperatures and the racial achievement gap in U.S. schools. Park’s study, which measured the impact of heat exposure on reduced learning, found that the negative effect of heat is more pronounced in school districts serving underrepresented minorities. “Over time, if you experience more hot days during the school year, and especially if you go to school in an area that doesn’t appear to have adequate school facilities, for whatever reason, those small cuts do seem to add up in a way that actually ends up being measurable in your standardized achievement,” said Park, an assistant professor of public policy. “To the extent that education is such an important component of economic mobility, one would be concerned about the cumulative nature of these cuts.”

New Research Shows Global Impact of Extreme Heat on Learning

/0 Comments/in /by

Extreme heat deepens educational inequities for students around the world, according to new research by R. Jisung Park, associate director of economic research at the UCLA Luskin Center for Innovation. Just published in the journal Nature Human Behaviour, Park’s study analyzed standardized achievement data for more than 144 million 15- to 19-year-olds in 58 countries, as well as detailed weather and academic calendar information. The findings showed that the rate of learning decreases with an increase in the number of hot school days. “Temperature is a surprisingly disruptive factor for students — both for high-stakes test-taking and for learning over the longer term,” said Park, an assistant professor of public policy specializing in environmental and labor economics. The new study broadens Park’s body of research into the effect of extreme heat on learning. Previous analyses of U.S. data showed that high temperatures can diminish student performance on standardized exams. In addition, minority and low-income students who attend U.S. schools that lack air conditioning are particularly vulnerable to the negative effects of heat, the research found. The latest study measured the effects on a global scale, showing that “heat disrupts learning across a wide range of climates and levels of development,” Park said. The research underscores the importance of policies aimed at improving physical learning environments. More broadly, it demonstrates that the impact of climate change on personal development can add up over time, possibly putting a brake on national economic growth and individual economic mobility.

 

Park on California as Ground Zero for Climate Disaster

/0 Comments/in /by

Assistant Professor of Public Policy R. Jisung Park spoke to the New York Times for a story about the engineering and land management innovations that led to California’s tremendous growth but also left it vulnerable to climate disaster. For generations, the state has moved vast quantities of water and suppressed wildfires to transform its arid and mountainous landscape into the “richest, most populous and bounteous place in the nation,” the article noted. While these accomplishments reflect the optimism that defines California, Park said, they were not designed to accommodate the increasingly harsh extremes of climate change. “The shocks are outside the range, in many cases, of historical experience,” he said. Park also noted that California’s engineered landscapes are not the only factor behind its high-impact disasters. The state’s size, geographic diversity and large population also expose it to an unusually wide range of extreme climate events.

Hecht on Infrastructure Projects’ Threat to Tropical Forests, Rural People’s Rights

/0 Comments/in /by

In an opinion piece published in Proceedings of the National Academy of Sciences, leading tropical scholars, including Professor Susanna Hecht of UCLA Luskin Urban Planning and the UCLA Institute of the Environment and Sustainability, warn that large-scale infrastructure projects in Latin America are undermining efforts to prevent climate change and biodiversity loss and enhance community land and resource rights. The researchers suggest alternative approaches to infrastructure, guided by an understanding of development that prioritizes human and environmental flourishing, equitable participation in decision-making, climate change mitigation, and a deepened relationship between science and public debate. The opinion is a response to the Group of 20’s emphasis on investment in large-scale infrastructure as a means of promoting economic growth. Governments are also promoting investment in infrastructure as a response to economic recession in the wake of the COVID-19 pandemic, according to the authors. They outline how science can guide infrastructure planning to emphasize sustainability and respect for human rights.

A Guardian story on the harmful impact of extreme heat on communities of color cited research by Assistant Professor of Public Policy R. Jisung Park. Data from the Union of Concerned Scientists shows that U.S. counties with large Black and Latino populations experience a disproportionately high number of days with temperatures above 100 degrees Fahrenheit, the article said. Research by Park, an environmental economist at the UCLA Luskin Center for Innovation, focuses on the effect of extreme heat on students’ ability to learn. His analysis of data from 10 million U.S. students over 15 years found that minority and low-income students who attend schools that lack air conditioning are particularly vulnerable. “Adapting to climate change is a matter of racial and economic justice, especially in schools,” said Park, who also discussed his research in an interview with America Adapts, beginning at minute 3:18.

Grant Funds Research Into Heat-Resilient Streetscapes

/0 Comments/in /by

When it comes to beating the Southern California heat, small-scale interventions can have a big impact. If you’ve ever waited for the bus on a hot summer day, you’ve felt how a shady tree or a covered bus shelter can help keep you cool. Despite these tangible benefits, few studies have focused on micro-scale, or street-level, interventions to reduce heat for pedestrians and transit riders. A new grant from the California Strategic Growth Council will fund a UCLA Luskin Center for Innovation analysis of these micro-scale cooling strategies to mitigate heat at bus stops and other streetscapes. V. Kelly Turner, assistant professor of urban planning and associate director of the Center for Innovation, will lead the project, which aims to empower communities, particularly disadvantaged and heat-vulnerable communities, to cost-effectively design cooling solutions for pedestrians and transit riders. This focus on active transportation can help reduce greenhouse gas emissions and local pollution while creating climate-resilient neighborhoods. Community-engaged research will center on four historically disadvantaged areas that are vulnerable to extreme heat — Pacoima, Watts/South Los Angeles, Ontario/Inland Valley and Oasis/Coachella Valley. These communities represent a range of climate zones and built environment forms in Southern California. The project, part of the Center for Innovation’s large body of climate adaptation and resiliency research, will also leverage ongoing partnerships among UCLA, Kounkuey Design Initiative and the state’s Transformative Climate Communities program. — Michelle Einstein

 

UCLA Supports Launch of California’s Transformative Climate Communities Program New Luskin Center for Innovation resource page tracks state's innovative effort to fight climate change

The UCLA Luskin Center for Innovation (LCI) has supported the launch of California’s innovative Transformative Climate Communities Program (TCC), one of the world’s most comprehensive sets of investments in local climate action. This includes developing the evaluation plan to track progress and evaluate outcomes from investments that could serve as a global model for community-scale climate action.

Now, inaugural progress reports for the first communities awarded TCC grants — Fresno, Ontario and Watts in Los Angeles — are authored by LCI researchers. These reports, and other resources related to LCI’s tracking of the groundbreaking efforts in local climate action, are centralized on a new TCC resource page. Policymakers, community stakeholders, researchers and others interested in local strategies to combat climate change can use this page to monitor progress, best practices and lessons learned over the five-year TCC grant implementation period that began in the spring of 2019.

The program to fund the development and implementation of neighborhood-level transformative plans that include multiple projects to reduce greenhouse gas emissions was authorized by Assembly Bill 2722 in 2016. In addition to fighting climate change, the program empowers disadvantaged communities impacted by poverty and pollution to support projects that advance their local economic, environmental and health goals.

“TCC may be the most holistic investment in neighborhood-scale and community-driven climate action anywhere on the planet,” said Jason Karpman MURP ’16, project manager of UCLA’s TCC evaluation. “Lessons learned from this new program could have potentially broad implications for climate action elsewhere.”

The California Strategic Growth Council serves as the lead administrator of TCC and awarded the first round of grants to Fresno ($66.5 million), Ontario ($33.25 million) and the Watts neighborhood of Los Angeles ($33.25 million).

Communities are empowered to customize their projects and plans based on their priorities and partnerships. The program includes mechanisms for accountability, including oversight from community members as well as third-party evaluation from academic researchers.

The team at the Luskin Center for Innovation and a similar group from the UC Berkeley Center for Resource Efficient Communities comprised the evaluation team for round 1 of TCC grants. UCLA researchers will take on a fourth TCC site for evaluation, Northeast Valley Los Angeles, during round 2 of TCC implementation.

The evaluation team worked with Fresno, Ontario and Watts stakeholders to create the Transformative Climate Communities Evaluation Plan, which UCLA published in late 2018. This research roadmap is being used to track and assess progress and results over a five-year period in those communities.

Now, UCLA has released the first annual report spanning the initial months of grant implementation.These reports highlight a wealth of data, including community conditions that could change during the five years of TCC implementation. Baseline trends relate to demographic, economic, energy, environmental, health, housing and transportation conditions.

“This first set of reports also documents progress on TCC implementation to date, including project milestones and personal stories of how TCC investments are affecting the lives of people who live and work in the pilot communities,” Karpman said. “This includes the voices of resident leaders in Ontario working to implement the site’s community engagement plan, a job trainee in Fresno learning how to install solar panels, and a high school student in Watts helping to expand a community garden.”

The first set of annual reports focuses on the period following the initial announcement of the TCC awards in 2018 through June 2019, which includes the first few months of project implementation. Common milestones across the three sites include laying the foundation for grant success, establishing partnerships and a governance structure, and launching new local initiatives around health, economic development and the environment.

UCLA’s page includes a number of other resources. Photos of residents and project staff show them working to bring their communities’ vision to reality. Supplemental methodological documentation such as open source code is available for those seeking to replicate findings. And staff bios show the evaluators involved with the project.

TCC is part of a suite of efforts, known as California Climate Investments, funded by the state’s cap-and-trade program. It unifies many of the California Climate Investments project types into a single, place-based initiative. Specifically, TCC funds the following project types:

  • construction of affordable housing near transit;
  • installation of rooftop solar and energy efficiency improvements for homes;
  • purchase of electric vehicles, including buses, that can run on clean energy instead of fossil fuels;
  • expansion of bus service coverage or frequency;
  • improvement and expansion of bike lanes and sidewalks;
  • planting of trees along bike and pedestrian routes and near buildings;
  • implementation of waste diversion programs, such as the collection and reuse of food waste and neighborhood-scale composting.

To maximize the benefits of these types of projects, grantees also must develop and implement the following transformative plans:

  • a community engagement plan to ensure TCC investments reflect the vision and goals of community members;
  • a workforce development plan to bring economic opportunities to disadvantaged and low-income communities;
  • a displacement avoidance plan to minimize the risk of gentrification and displacement of residents and businesses following neighborhood improvements.

 

 

Turner on Effects of ‘Cool Pavement’

/0 Comments/in /by

KNX 1070 spoke with V. Kelly Turner, assistant professor of urban planning, about Los Angeles’ “cool pavement” project, part of an initiative to test strategies to adapt to climate change. The city has been pouring reflective coating on dozens of roads, and Turner is among the researchers measuring the effects. “Cool pavement is working. It greatly reduces surfaces temperatures,” she found. But she noted that the energy reflected from the cooler surfaces are radiated out and can be absorbed by the human body. As a result, pedestrians walking on “cool pavement” surfaces during the middle of the day may feel warmer, Turner found.

 

Turner Tracks Effectiveness of ‘Cool Pavement’ Technology

A CityLab story on the city of Los Angeles’ efforts to pursue “cool pavement” technologies to address rising urban temperatures featured the research of V. Kelly Turner, assistant professor of urban planning. While other cool pavement studies have measured surface and air temperature, Turner’s research is the first to focus on “mean radiant temperature,” which is most related to thermal comfort. Turner and Ariane Middel, assistant professor of arts media and engineering at Arizona State University, studied unshaded streets in Pacoima and Sun Valley that had been coated with an asphalt mixture called CoolSeal, which reflects, rather than absorbs, the energy from sunlight. They measured air temperature, wind speed, humidity and radiation from morning to sundown, and their preliminary findings will soon be published by the American Meteorological Society. The project is one part of a greater effort to collect data on the effectiveness of strategies to address so-called urban heat islands.
