$34.6M investment in ASU to help create reliable internet access and training for the region

September 29, 2022

Funding makes ASU home to the largest university-led digital equity initiative in the country

Editor’s note: This story is featured in the 2022 year in review.

Like food, clothing and shelter, the internet has become a basic need. Today, access is a determining factor for quality of life as it connects people to vital health care, learning experiences and work opportunities.

Yet, across Arizona, reliable access to high-speed broadband remains unequal. In Maricopa County, some neighborhoods report as many as 70% of residents are still without adequate internet performance needed for remote work, downloading homework or streaming.

Arizona State University is leading an effort to bridge this divide. The Maricopa County Board of Supervisors recently voted unanimously to provide ASU and its collaborators $34.6 million through 2026 to advance broadband, community support, equipment and training across Maricopa County, which includes the metro Phoenix area.

The funding makes ASU home to the largest university-led digital equity initiative in the country. ASU Enterprise TechnologySun Corridor Network and the 501(c)(3) Digital Equity Institute will lead the effort along with hundreds of faculty, students and staff to bolster digital proficiency and distribute internet-connected devices to those in need.

"The idea of providing access at scale is embedded in the ASU Charter,” said Chris Howard, executive vice president and chief operating officer of the ASU Public Enterprise, which aims to design, build and oversee a new model for a national university. “Our digital equity agreement with Maricopa County signifies that as a public enterprise our commitment extends well beyond ASU's physical locations."

Mary Haddad, an ASU undergraduate student, shared at an ASU Town Hall her vision for the future where the internet is readily accessible for all: “In an ideal future, we are providing training, online tools and resources, making sure that we are continuously available if they need help and support.”

Partnering for social impact

It took an agile collaboration between government, education, community and industry to get to the point of funding. When the White House administration announced the American Rescue Plan, a $1.9 trillion economic stimulus package, broadband was featured prominently on the national solutions agenda. 

Seeing the opportunity and the need, a group of regional partners sprung into action.

A broadband task force convened under the umbrella of The Connective, Greater Phoenix’s smart region consortium and an initiative of the Partnership for Economic Innovation. The group consisted of government officials, Maricopa County and a technical advisory team led by ASU and the Digital Equity Institute.

“Through the broadband task force, we have an opportunity to build a region where every person is a fully engaged and active participant in shaping the future of the community in which they live,” said Chris Camacho, president and CEO of the Greater Phoenix Economic Council, a task force member and a board member of the Partnership for Economic Innovation. 

The nearly $35 million in funding to ASU comes through the American Rescue Plan package, awarded by Maricopa County. 

“It is only through a collaborative partnership and proactive leadership that we will begin to address these structural barriers at a regionwide level to ensure the digital economy reaches all Greater Phoenix households,” said Bill Gates, Maricopa County Board of Supervisors chairperson.

Moving forward, collaboration will remain at the center. ASU Enterprise Technology, Sun Corridor Network and the Digital Equity Institute will partner to connect community anchor institutions, such as schools, health clinics and other neighborhood assets, and provide educational programs that support communities’ journeys from digital inequity to full participation. 

Work is aready underway to build a better connected community 

Recent broadband installation pilots with Phoenix’s Isaac School District, led by ASU’s Watts College of Public Service and Community Solutions and Enterprise Technology, already revealed positive impacts from improving access in K–12. Now, the implications of this latest funding allocation reach every facet of learning, working and thriving. 

“The Digital Equity Institute is committed to taking a holistic approach to leveling the playing field,” said Erin Carr-Jordan, managing director of the Digital Equity Institute. “Through meaningful collaboration, we can amplify the voices of disadvantaged communities and provide people with access to the knowledge, skills and support needed to fully participate in every aspect of society, democracy and the economy.” 

ASU is already analyzing the data and preparing the geographic maps as the basis for the forthcoming broadband installations.

“We must know where the gaps in service are, and this granular level of data will help us scale to serve more of our communities,” said Lev Gonick, chief information officer at ASU. “We want to make sure that the resources allocated to solving this pervasive, systemic challenge are directed to where they are most needed."

This Monday, Oct. 3, marks the first Arizona Digital Inclusion Celebration Summit, hosted by the Digital Equity Institute and ASU’s ShapingEDU — free and open to all.

Gates, from the Maricopa County Board of Supervisors, will kick off the event by sharing the current and future state of digital equity. Government officials, broadband experts, digital literacy champions and other key groups will detail what the community needs to know — and what comes next.

Climate change could mean more intense locust outbreaks, threat to food security

ASU researchers develop new predictive model based on locust digestion

September 29, 2022

A new study by a research team from Arizona State University has found that climate change will dramatically increase the intensity of locust swarms, resulting in even more crops lost to insect pests and threatening food security. 

The study, recently published in Ecological Monographs, outlines the results of considerable data gathered on the physiology of South American locusts, and demonstrates that species distribution models that consider physiology in addition to temperature may reshape what we can expect to see as climate change continues.  ASU PhD Jacob Youngblood using a net to capture locusts in a field.

"One unique aspect of our study is that we combined many different research approaches, including field observations, laboratory experiments and computational modeling,” said Jacob Youngblood, recent ASU biology PhD graduate and first author on the study.

“To combine these approaches, we assembled a diverse team of researchers, which included physiologists, ecologists, entomologists and agriculturists. Collaborating with such a diverse team enabled us to study the effects of climate change on multiple aspects of locust biology."

The international team included researchers from ASU’s Global Locust Initiative: Assistant Professor Arianne Cease, President’s Professor Michael Angilletta and Professor Jon Harrison from the School of Life Sciences, and postdoc Stav Talal from the Global Institute of Sustainability and Innovation, as well as innovators and collaborators in South America.

Plagues of old

Since at least the days of the pharaohs of ancient Egypt in 3,200 B.C., locusts have been erupting into massive swarms that descend upon crops and plant life, causing almost total devastation. 

Why do these destructive swarms suddenly occur?

Just like people, locusts can be either shy or gregarious. For the most part, locust populations can spend several seasons in a low-density population, called a solitarious phase. The locusts are a cryptic brown or green — shy, solitary and relatively harmless on a global economic scale. However, when circumstances are just right, the locust numbers swell to overcrowding, triggering a drastic switch to a gregarious phase — social, brightly colored and capable of forming migratory swarms of 80 million locusts per square kilometer.

With each locust consuming up to 2 grams of vegetation every day, a swarm of this size can travel up to 90 miles a day, consuming the same amount of food as 35,000 people. It’s no wonder they are considered the world’s most devastating pest. 

To help unravel the driving forces behind swarms, the team studied the physiology of the South American locust (Schistocerca cancellata). 

"Conducting the research in Paraguay was really exciting for me because it was the first time I saw locust outbreaks in person,” Youngblood said. “Seeing tens of thousands of locusts together really made me realize how big of a problem locusts can be for local farmers and land managers.

“Most research on locusts has been performed on colonies that have been raised in the lab for years, so our research was a rare opportunity to study outbreaking locusts in their natural environment. This opportunity would not have been possible without the help of our colleagues in Argentina, Bolivia and Paraguay, who have been managing these outbreaks for the past seven years.”

Modeling the future 

To try to predict where swarms will migrate, and where crops will be threatened, scientists use species distribution models — computer algorithms that predict the distributions of a species across a geographic area using environmental data. 

The most common modeling technique has been correlative models. However, given the unknown variables inherent in a changing global climate, this method has lost its efficacy. 

The research team employed a mechanistic modeling approach, gathering data about locust physiology to inform their model. In this case, the researchers measured how quickly locusts digest food in different environments.

“Jacob’s study is a beautiful example, demonstrating that predicting how animals will respond to climate change, and helping humans survive and prosper despite climate change, is going to require in-depth studies of the intricate inner workings of our fellow biological organisms,” said Harrison. 

The energy to swarm

A key factor of environmental data used for traditional correlative models is temperature, which has major impacts on locusts' eating habits. 

However, this environmental data alone cannot adequately predict the effects of climate change on locust populations. First, locusts can exist and eat in a variety of temperatures. And as generalist herbivores who can travel long distances for readily available food, locusts can fill their stomachs with food faster than they can digest it. 

While locusts can and will eat in a wide range of temperatures, the optimal temperature for digestion is much more specific. 

Youngblood and his associates homed in on this element as a decisive criterion for a thriving locust population likely to result in outbreak scenarios. 

The team measured how thermal conditions affected the rates of eating and digesting for field-captured locusts and used this data to model energy gain in both current and future climate scenarios. Next, they established this new data as a predictive variable for a new species distribution model that predicted the spread of locust outbreaks across multiple scenarios. 

Their predictions show that locusts will be able to assimilate far more energy in future climates than current climates, between 8% and 17% more energy per wet season than currently, proportional to how much warmer it is. 

Typically, the South American locusts complete only two generations per growing season. This increased energy per wet season would cause a shortening of generation times and fuel population growth, leading to more swarms. Future, warmer climates allow populations to grow and develop faster, supporting more years with three generations per season, and outbreaks more likely.

Migratory populations of South American locusts are also expected to expand their range away from the equator due to climate change. Models that consider locust physiology actually predict a smaller range of expansion than typical correlative models, but the physiology-based models also predict an increase in population growth rate, resulting in even greater crop damage. 

Previous models predicted crop loss from insect pests to increase by 10%–25% under climate change, but scientists did not know if these predictions were relevant to the South American locust. The new model created by Younglood matched the earlier models, predicting a 17% increase in crop losses from South American locusts. 

"Climate change has become a keynote theme in scientific research literature,” said collaborator Eduardo Trumper of the National Agricultural Technology Institute in Argentina. “Plenty of it is correlational. The excitement of collaborating in this article stems from the exploration of likely mechanisms involved in the response of a high-impact agricultural pest to warming."

“Together, this information should help farmers and governments plan ahead for the next outbreak,” said Youngblood. “And although more research is needed, this physiological modeling approach could help predict outbreaks for other locust species too.”

Global collaboration

This research is part of an ongoing partnership between ASU’s Global Locust Initiative (GLI) and national plant protection organizations, farmers groups and universities in Argentina, Bolivia and Paraguay that started at the beginning of the South American locust upsurge. 

“Locusts are part of complex social-ecological-technological systems that require teams to work together across disciplines, sectors and boundaries,” said Cease, GLI director. 

In 2020, GLI led a stakeholder workshop in Argentina to bring diverse participants together to formalize what they experience on a daily basis as locust governance. 

“All of these stakeholders and areas of expertise are critical,” said Cease. “And understanding locust biology and being able to predict when and where outbreaks will occur is a key piece of the puzzle where we have surprisingly limited research globally, relative to the challenge. Jacob’s collaborative work building these models is an important advancement for biology and food security.”
