Easing the problem of homelessness will require communities to build more affordable housing, and that will require creating a new narrative with people who oppose it, according to two Arizona State University experts.

“We need to get businesses, public safety, education and neighborhood groups on board,” said Senior Sustainability Scientist Joanna Lucio, associate dean of academic affairs and an associate professor in the School of Public Affairs.

Climate change is complicating land conservation practices because of how it alters land over time. Among other things, climate change is raising new questions about perpetual conservation easements — a critical land preservation tool relied upon by government agencies and nonprofit land trusts. A six-author team that conducted an unprecedented analysis of the structuring of conservation easements in the face of rapid climate change has been awarded the 2019 Morrison Prize, an honor established in 2015 and administered through the program on Law and Sustainability at the Sandra Day O’Connor College of Law at Arizona State University.

Honeybees frequently make international news, as their global decline threatens the world’s food supply. Since honeybees pollinate the majority of crops that humans use for food, scientists have been searching for a way to maintain healthy bee populations.

Now, researchers with Arizona State University’s School of Life Sciences and the University of Helsinki are one step closer to understanding the complex immune mechanism that protects honeybees from diseases in their environments.

At Arizona State University, successful results often come from collaborative action, especially when making events more eco-friendly. Thanks to ASU students and the work of two ASU sustainability leaders, Colin Tetreault and Lesley Michalegko, the NCAA Women’s Collegiate Triathlon National Championships that took place at Tempe Town Lake on November 4, 2018, was a more sustainable endeavor.

Tetreault is an instructor in the School of Sustainability and Michalegko is a program manager for University Sustainability Practices. Through mutual effort and the support of students, they made the NCAA triathlon a place where functionality met sustainability. They found ways to reduce waste, save money, and increase the fan and competitor experience while simultaneously driving revenue.

Climate change. Species loss. Pollution.

These are well-known consequences of economic development threatening human and ecological health. International efforts to mitigate these threats are also familiar, including reducing greenhouse gas emissions, protecting endangered animals and cleaning our air and waterways.

However, perhaps the most crucial threat is also the most neglected — land degradation.

Approximately 1.3 billion people depend on polluted or degraded agricultural land. This leads to reduced agricultural productivity and access to water and increased carbon emissions. It is a complex problem with serious implications for food security, health and sustainable development.

Around the world, scientists are solving serious issues using modern technology. Whether the solution is genetically modified, malaria-fighting mosquitoes or other gene editing technologies, Arizona State University sustainability scientist James P. Collins is calling for careful risk assessment.

Collins, the Virginia M. Ullman Professor of Natural History and the Environment at ASU's School of Life Sciences, co-authored a paper published in the journal "Science." The authors urgently encourage global governance to review new technologies on a a case-by-case basis — a decision-making process that must include the local communities that would feel the biggest and most immediate effects.

Still most widely associated with the invention of velcro, ASU researchers are walking the talk of biomimicry with a newly renovated office space and a new seed exhibit they hope will capture the imagination of innovators seeking solutions for complex human problems.

"Seeds continue to offer a bottomless design and engineering trove for many other innovations," said Heidi Fischer, assistant director at the Biomimicry Center. "We hope that our exhibition can provide new models for some of these innovations."

Titled “Designed to Move: Seeds that Float, Fly or Hitchhike through the Desert Southwest,” the exhibit, opening Oct. 30 in the Design School South Gallery on ASU's Tempe campus is offering viewers an extraordinary look at the beauty of desert seeds as captured through the macro photography lens of Taylor James, an alumni of ASU’s Masters of Fine Arts program.

At an October 5 Food and Thought event sponsored by Arizona State University College of Health Solutions, Author Adrian Miller spoke about the importance of African-Americans to the executive kitchen. Miller, a James Beard Award winner, signed copies of his new book at the event, which also featured food tastings an an audience question-and-answer session.

Miller’s book, "The President’s Kitchen Cabinet: The Story of African-Americans Who Have Fed Our First Families, from the Washingtons to the Obamas," takes a look at some of the most pivotal characters in the White House’s kitchen history, some of which he spoke about at the event hosted by the ASU College of Health Solutions.

The reception also featured some of the recipes included in the book that were prepared for presidents and their families throughout history, including first lady Caroline Harrison’s deviled almonds and a baked macaroni and cheese that was served to Thomas Jefferson.

The Arizona State University Zero Waste department collected 58,000 pounds of reusable items in the spring 2018 Ditch the Dumpster event, more than any previous years.

Ditch the Dumpster is a campus program to collect and redistribute or divert student's items when they move out of the dorms. Collected items are donated to organizations including Big Brothers Big Sisters, Goodwill, St. Mary's Food Bank, The Center for Habilitation, and United Food Bank.

This year, Zero Waste collected 58,820 pounds of reusable clothing, electronics, furniture, and other household items. On top of these donations, 97,480 pounds of materials were recycled. The Ditch the Dumpster program also donated more than $5,400 in scholarships for local students.

Using a combination of field instrumentation, unmanned aerial vehicles and a hydrologic model, a team of researchers from Arizona State University and the Jornada Long-Term Ecological Research Program of the National Science Foundation has been studying the fate of monsoon rainfall and its impact on groundwater recharge in the Chihuahuan Desert of New Mexico.

Their findings, recently published in the journal Water Resources Research, explain how a surprising amount of rainfall, nearly 25 percent, from monsoon storms is absorbed into small stream beds and percolates into the groundwater system. The researchers identified factors affecting the percolation process through the use of a numerical model that reproduced the long-term observations obtained at a highly instrumented research site.

“The results of this study show that monsoon storms serve an important role in recharging groundwater aquifers near the point of runoff generation,” said ASU hydrologist Enrique Vivoni of the School of Earth and Space Exploration and the School of Sustainable Engineering and the Built Environment. “This is an essential process that banks renewable surface water for future use as a groundwater resource in the arid Southwest and throughout the world.”

New solar energy research from Arizona State University demonstrates that silicon-based tandem photovoltaic modules, which convert sunlight to electricity with higher efficiency than present modules, will become increasingly attractive in the U.S.

A paper that explores the costs vs. enhanced efficiency of this new solar technology appears in Nature Energy this week. The paper is authored by ASU Ira A. Fulton Schools of Engineering Assistant Research Professor Zhengshan J. Yu, graduate student Joe V. Carpenter and Assistant Professor Zachary Holman.

The Department of Energy’s SunShot Initiative was launched in 2011 with a goal of making solar cost-competitive with conventional energy sources by 2020. The program attained its goal of $0.06 per kilowatt-hour three years early, and a new target of $0.03 per kilowatt-hour by 2030 has been set. Increasing the efficiency of photovoltaic modules is one route to reducing the cost of the solar electricity to this new target. If reached, the goal is expected to triple the amount of solar installed in the U.S. in 2030 compared to the business-as-usual scenario.

Three times farther from the sun than Earth, a massive asteroid made of metal floats in space between Mars and Jupiter. Its name is Psyche, and it could be the core of an early planet that survived violent collisions when the solar system was forming. Psyche was the sixteenth asteroid ever discovered, in 1852, but only recently has a spacecraft mission been initiated by Arizona State University and NASA to study this asteroid in more depth.

Unlike most other known asteroids, which are primarily rocky, Psyche appears to be made almost entirely of nickel-iron metal — much like Earth’s own core. According to ASU’s Psyche website, “The asteroid Psyche may be able to tell us how Earth’s core and the cores of the other terrestrial (rocky) planets came to be.” Scientists can’t investigate Earth’s core directly, so studying an asteroid with a similar makeup may be the next best thing.

ASU leads the Psyche mission, and NASA’s Jet Propulsion Laboratory is responsible for its management, operations and spacecraft navigation. The spacecraft is slated to launch in 2022, and then it will spend nearly four years cruising through space, using the gravitational field of Mars to increase in speed, until it reaches Psyche in 2026. Upon arrival, the spacecraft will orbit Psyche for 21 months, mapping and studying the asteroid’s properties.

Earth is experiencing a Great Transition as its peoples slowly shift from fossil fuels to wind, plants, natural processes and our sun.

It’s not the first time people have changed where they get their energy sources, but as energy historian Chris Jones

said, what makes the Great Transition different is that this time we need to get rid of something, instead of just adding something. Climate change is the binding constraint.

Arizona State University is part of a new coalition of 13 leading research universities committed to tackling climate change. The group — called the University Climate Change Coalition — includes universities from the United States, Canada and Mexico.

Read the full story on ASU Now to learn how ASU energy scholars are confronting the difficult challenges of transforming the climate narrative and enacting change through policy.

As many as 1.3 billion people lack access to electrical power, according to Senior Sustainability Scientist Nathan Johnson. That's why the ASU engineer – who directs the Laboratory for Energy And Power Solutions – is advancing technologies for electrical-grid modernization and off-grid electrification.

One of these solutions is the microgrid, which provides independent power generation and storage. Johnson and the LEAPS team are developing microgrids that are more technically and economically viable – easier to design, scale and transport. On top of providing the world's poorest and most remote communities with stable power, this technology can improve scenarios like disaster relief and medical care.

Johnson’s approach to military microgrids won a TechConnect Defense Innovation Award at the Defense Innovation Technology Acceleration Challenges Summit.

If cities in developing nations don’t address their burgeoning slums, poverty will increase, political instability will heighten and human misery will continue.

That's according to Senior Sustainability Scientist José Lobo, one of the authors of a 2018 report presented at the World Urban Forum. The report detailed the efforts of Know Your City, an initiative that organized slum residents in 103 cities to profile, enumerate and map their communities.

“The central premise of community data collection is that the data collected becomes an instrument to foster a dialogue among the many different parties (communities, public agencies, governments, NGOs, international funding agencies) about the design and implementation of effective solutions,” Lobo said.

Chris Wharton, director of the Food Systems Transformation Initiative, gives the latest KEDTalk hosted by ASU's Knowledge Enterprise Development. "We live in a world of wild, damaging, unsustainable excess," he says, and the solution requires a rapid, transformational response. By revealing what is hidden in plain sight, Wharton illuminates a path to health, wealth, happiness and sustainability through values-based behavior change.

ASU is part of a new coalition of 13 leading research universities committed to tackling climate change. The group – called the University Climate Change Coalition, or UC3 – includes distinguished universities from the United States, Canada and Mexico.

Each university has committed to mobilizing its resources and expertise to help businesses, cities and states achieve their climate goals. Specific UC3 goals include hosting cross-sector forums and producing a climate mitigation and adaptation report.

The formation of UC3 was announced at the Second Nature 2018 Higher Education Climate Leadership Summit.

There are plenty of sci-fi stories set in post-apocalyptic scenarios where urban ruins crumble amid mass environmental destruction, and the remaining human communities struggle to find food, water and shelter. Charlie Jane Anders’ short sci-fi story “The Minnesota Diet” is different, and the Food Systems Transformation Initiative (FSTI) director Chris Wharton explains why in a special Future Tense article for Slate.

Anders’ story begins in fictional New Lincoln, a technologically advanced, future urban city seemingly well-insulated from agricultural vulnerabilities—until it isn’t.

Wharton says “The Minnesota Diet” offers opportunities for backcasting and reflection on our current behaviors when it comes to our food system. Anders’ story lends insight into more than just the technological efficiencies required for food production and delivery systems — it invites us to think critically about the choices we make right now with the resources we have today.

While Habitat for Humanity CEO Jonathan Reckford was in Phoenix as a speaker for the Wrigley Lecture Series, he stopped by the public radio station KJZZ to talk about the importance of affordable housing.

"Housing is complicated and expensive. It's hard to tackle," Reckford said in the segment. "The only real solutions are to get the public sector, the private sector and the nonprofit community working together on community transformation."

“What we’ve seen — and the data is very strong — is that mixed-income, mixed-use communities are the healthiest approach for everybody involved,” Reckford told the show's host Mark Brodie. Reckford went into more detail about affordable housing in his lecture, "Housing for Inclusive and Equitable Cities," sponsored by the Julie Ann Wrigley Global Institute of Sustainability at Arizona State University.

$200 billion worth of consumer products are now managed using tools created by The Sustainability Consortium – an organization run by ASU and the University of Arkansas – according to the consortium's 2017 impact report.

TSC helps companies define, develop and deliver more sustainable products by providing them with science-based tools. Its members – which exceed 100 and include brands like Walmart, Amazon and Walgreens – have access to research insights in almost 130 product categories. To date, 85 percent of consumer goods are covered.

“We are now seeing the tide changing in the number of companies committing to creating sustainable products for a more sustainable planet,” said TSC Chief Executive Euan Murray.
