« Researchers Find that to Achieve Long-term Sustainability, Urban Systems Must Tackle Social Justice and Equity
Newswise — Inclusivity and understanding past policies and their effects on underserved and marginalized communities must be part of urban planning, design, and public policy efforts for cities.
An international coalition of researchers — led by Georgia Tech — have determined that advancements and innovations in urban research and design must incorporate serious analysis and collaborations with scientists, public policy experts, local leaders, and citizens. To address environmental issues and infrastructure challenges cities face, the coalition identified three core focus areas with research priorities for long-term urban sustainability and viability. Those focus areas should be components of any urban planning, design, and sustainability initiative.
The researchers found that the core focus areas included social justice and equity, circularity, and a concept called “digital twins.” The team — which consists of 13 co-authors and scholars based in the U.S., Asia, and Europe — also provided guidance and future research directions for how to address these focus areas. They detailed their findings in the Journal of Industrial Ecology, published in January 2023.
“Climate change has certainly increased the amount and intensity of extreme weather events and because of that, it makes our decision making today critical to the manner in which our economy and our day to day lives can operate,” said Joe F. Bozeman III, the lead author and an assistant professor in Georgia Tech’s School of Civil and Environmental Engineering. He is also the director of Tech’s Social Equity & Environmental Engineering Lab. “Our quality of life can be negatively affected if we don’t make good decisions today.”
Three core areas of focus to achieve urban sustainability
The researchers’ first core focus area, justice and equity, addresses innovations and trends that disproportionately benefit middle and high-income communities. Trends like IoT, “smart cities,” and the urban “green movement” are part of a broader push by cities to become more sustainable and resilient. But communities of color and low-income neighborhoods — the same areas often home to environmental contaminations, infrastructure challenges, and other hazards — have often been overlooked.
The researchers’ findings showed a consistent trend with marginalized communities across several countries, including Canada, the Netherlands, India, and South Africa. They call for mandatory equity analyses which incorporate the experiences and perspectives of these marginalized communities, and, more importantly, ensure members of those communities are actively engaged in decision-making processes.
“Planning, professional, and community stakeholders,” the researchers write in the paper, “should recognize that working together gets cities closer to harmonizing the technological and social dimensions of sustainability.”
The second focus area, circularity, addresses resource consumption of staple commodities including food, water, and energy; the waste and emissions they generate; and the opportunities to increase conservation of those resources by boosting efficiencies.
“What we mean by circularity is basic reuse, remanufacturing, and recycling efforts across the entire urban system — which not only includes cities and under resourced areas within those cities — but also rural communities that supply and take resources from those city hubs,” Bozeman said. The idea is aligned with the circular economy concept which addresses the need to move away from the resource-wasteful and unsustainable cycle of taking, making, and throwing away.
Instead, the researchers argue, cities should look for ways to improve efficiency and maximize local resource use. That has potential benefits not only for urban areas, but rural communities, too. One example, Bozeman said, is the Lifecycle Building Center in Atlanta. It takes old building supplies and sells them locally for reuse.
“By doing that, they’re at the beginning stages of creating an economic system, a regional engine where we share resources between cities and rural areas,” he said. “We can start creating an economic framework, not only where both sides can make money and get what they need, but something that can actually turn into a sustainable economic engine without having to rely on another state or another country’s import or export economic pressures.”
To strengthen circularity and make it more robust, the researchers call for more expansive metrics beyond measuring recycling rates and zero waste efforts, to include other parts of the supply chain that may yield new ideas and solutions.
The third focus area, digital twins, addresses the development of automated technologies in smart buildings and infrastructure, such as traffic lights to respond to weather and other environmental factors.
“Let’s say there’s a heavy rain event and that the rainwater is being stored into retainment,” said Bozeman. “An automated system can open another valve where we can store that water into a secondary support system, so there’s less flooding, and that can happen automatically, if we utilize the concept of digital twins.”
Creating a new urban planning model
The research came about as part of the mission of the Sustainable Urban Systems Section of the International Society for Industrial Ecology, which aims to be a conduit for scientists, engineers, policymakers, and others who want to marry environmental concerns and economic activity. Bozeman is a board member of the Sustainable Urban Systems Section.
“In that role, part of we do is set a vision and foundation for how other researchers should operate within the city and urban system space,” he said.
For urban sustainability, engineers and policy makers must come to the table and make collective decisions around social justice and equity, circularity, and the digital twins concepts.
“I think we’re at a really critical decision point when it comes to engineers and others being able to do work that is forward looking and human sensitive,” said Bozeman. “Good decision making involves addressing social justice and equity and understanding its root causes, which will enable cities to create solutions that integrate cultural dynamics.”

How a 22-year-old George Washington learned how to lead, from a series of mistakes in the Pennsylvania wilderness
This Presidents Day, I’ve been thinking about George Washington − not at his finest hour, but possibly at his worst.
Christopher Magra, University of Tennessee
This Presidents Day, I’ve been thinking about George Washington − not at his finest hour, but possibly at his worst.
In 1754, a 22-year-old Washington marched into the wilderness surrounding Pittsburgh with more ambition than sense. He volunteered to travel to the Ohio Valley on a mission to deliver a letter from Robert Dinwiddie, governor of Virginia, to the commander of French troops in the Ohio territory. This military mission sparked an international war, cost him his first command and taught him lessons that would shape the American Revolution.
As a professor of early American history who has written two books on the American Revolution, I’ve learned that Washington’s time spent in the Fort Duquesne area taught him valuable lessons about frontier warfare, international diplomacy and personal resilience.
The mission to expel the French
In 1753, Dinwiddie decided to expel French fur trappers and military forces from the strategic confluence of three mighty waterways that crisscrossed the interior of the continent: the Allegheny, Monongahela and Ohio rivers. This confluence is where downtown Pittsburgh now stands, but at the time it was wilderness.
King George II authorized Dinwiddie to use force, if necessary, to secure lands that Virginia was claiming as its own.
As a major in the Virginia provincial militia, Washington wanted the assignment to deliver Dinwiddie’s demand that the French retreat. He believe the assignment would secure him a British army commission.
Washington received his marching orders on Oct. 31, 1753. He traveled to Fort Le Boeuf in northwestern Pennsylvania and returned a month later with a polite but firm “no” from the French.
Dinwiddie promoted Washington from major to lieutenant colonel and ordered him to return to the Ohio River Valley in April 1754 with 160 men. Washington quickly learned that French forces of about 500 men had already constructed the formidable Fort Duquesne at the forks of the Ohio. It was at this point that he faced his first major test as a military leader. Instead of falling back to gather more substantial reinforcements, he pushed forward. This decision reflected an aggressive, perhaps naive, brand of leadership characterized by a desire for action over caution.
Washington’s initial confidence was high. He famously wrote to his brother that there was “something charming” in the sound of whistling bullets.
The Jumonville affair and an international crisis
Perhaps the most controversial moment of Washington’s early leadership occurred on May 28, 1754, about 40 miles south of Fort Duquesne. Guided by the Seneca leader Tanacharison – known as the “Half King” – and 12 Seneca warriors, Washington and his detachment of 40 militiamen ambushed a party of 35 French Canadian militiamen led by Ensign Joseph Coulon de Jumonville. The Jumonville affair lasted only 15 minutes, but its repercussions were global.
Ten of the French, including Jumonville, were killed. Washington’s inability to control his Native American allies – the Seneca warriors executed Jumonville – exposed a critical gap in his early leadership. He lacked the ability to manage the volatile intercultural alliances necessary for frontier warfare.
Washington also allowed one enemy soldier to escape to warn Fort Duquesne. This skirmish effectively ignited the French and Indian War, and Washington found himself at the center of a burgeoning international crisis.
Defeat at Fort Necessity
Washington then made the fateful decision to dig in and call for reinforcements instead of retreating in the face of inevitable French retaliation. Reinforcements arrived: 200 Virginia militiamen and 100 British regulars. They brought news from Dinwiddie: congratulations on Washington’s victory and his promotion to colonel.
His inexperience showed in his design of Fort Necessity. He positioned the small, circular palisade in a meadow depression, where surrounding wooded high ground allowed enemy marksmen to fire down with impunity. Worse still, Tanacharison, disillusioned with Washington’s leadership and the British failure to follow through with promised support, had already departed with his warriors weeks earlier. When the French and their Native American allies finally attacked on July 3, heavy rains flooded the shallow trenches, soaking gunpowder and leaving Washington’s men vulnerable inside their poorly designed fortification.
The battle of Fort Necessity was a grueling, daylong engagement in the mud and rain. Approximately 700 French and Native American allies surrounded the combined force of 460 Virginian militiamen and British regulars. Despite being outnumbered and outmaneuvered, Washington maintained order among his demoralized troops. When French commander Louis Coulon de Villiers – Jumonville’s brother – offered a truce, Washington faced the most humbling moment of his young life: the necessity of surrender. His decision to capitulate was a pragmatic act of leadership that prioritized the survival of his men over personal honor.
The surrender also included a stinging lesson in the nuances of diplomacy. Because Washington could not read French, he signed a document that used the word “l’assassinat,” which translates to “assassination,” to describe Jumonville’s death. This inadvertent admission that he had ordered the assassination of a French diplomat became propaganda for the French, teaching Washington the vital importance of optics in international relations.
Lessons that forged a leader
The 1754 campaign ended in a full retreat to Virginia, and Washington resigned his commission shortly thereafter. Yet, this period was essential in transforming Washington from a man seeking personal glory into one who understood the weight of responsibility.
He learned that leadership required more than courage – it demanded understanding of terrain, cultural awareness of allies and enemies, and political acumen. The strategic importance of the Ohio River Valley, a gateway to the continental interior and vast fur-trading networks, made these lessons all the more significant.
Ultimately, the hard lessons Washington learned at the threshold of Fort Duquesne in 1754 provided the foundational experience for his later role as commander in chief of the Continental Army. The decisions he made in Pennsylvania and the Ohio wilderness, including the impulsive attack, the poor choice of defensive ground and the diplomatic oversight, were the very errors he would spend the rest of his military career correcting.
Though he did not capture Fort Duquesne in 1754, the young George Washington left the woods of Pennsylvania with a far more valuable prize: the tempered, resilient spirit of a leader who had learned from his mistakes.

The Building That Proved Los Angeles Could Go Vertical
Los Angeles once banned skyscrapers, yet City Hall broke the height limit and proved high-rise buildings could be engineered safely in an earthquake zone.
How City Hall Quietly Undermined LA’s Own Height Limits
The Knowledge Series | STM Daily News
For more than half a century, Los Angeles enforced one of the strictest building height limits in the United States. Beginning in 1905, most buildings were capped at 150 feet, shaping a city that grew outward rather than upward.
The goal was clear: avoid the congestion, shadows, and fire dangers associated with dense Eastern cities. Los Angeles sold itself as open, sunlit, and horizontal — a place where growth spread across land, not into the sky.
And yet, in 1928, Los Angeles City Hall rose to 454 feet, towering over the city like a contradiction in concrete.
It wasn’t built to spark a commercial skyscraper boom.
But it ended up proving that Los Angeles could safely build one.
A Rule Designed to Prevent a Manhattan-Style City
The original height restriction was rooted in early 20th-century fears:
- Limited firefighting capabilities
- Concerns over blocked sunlight and airflow
- Anxiety about congestion and overcrowding
- A strong desire not to resemble New York or Chicago
Los Angeles wanted prosperity — just not vertical density.
The height cap reinforced a development model where:
- Office districts stayed low-rise
- Growth moved outward
- Automobiles became essential
- Downtown never consolidated into a dense core
This philosophy held firm even as other American cities raced upward.
Why City Hall Was Never Meant to Change the Rules
City Hall was intentionally exempt from the height limit because the law applied primarily to private commercial buildings, not civic monuments.
But city leaders were explicit about one thing:
City Hall was not a precedent.
It was designed to:
- Serve as a symbolic seat of government
- Stand alone as a civic landmark
- Represent stability, authority, and modern governance
- Avoid competing with private office buildings
In effect, Los Angeles wanted a skyline icon — without a skyline.
Innovation Hidden in Plain Sight
What made City Hall truly significant wasn’t just its height — it was how it was built.
At a time when seismic science was still developing, City Hall incorporated advanced structural ideas for its era:
- A steel-frame skeleton designed for flexibility
- Reinforced concrete shear walls for lateral strength
- A tapered tower to reduce wind and seismic stress
- Thick structural cores that distributed force instead of resisting it rigidly
These choices weren’t about aesthetics — they were about survival.
The Earthquake That Changed the Conversation
In 1933, the Long Beach earthquake struck Southern California, causing widespread damage and reshaping building codes statewide.
Los Angeles City Hall survived with minimal structural damage.
This moment quietly reshaped the debate:
- A tall building had endured a major earthquake
- Structural engineering had proven effective
- Height alone was no longer the enemy — poor design was
City Hall didn’t just survive — it validated a new approach to vertical construction in seismic regions.
Proof Without Permission
Despite this success, Los Angeles did not rush to repeal its height limits.
Cultural resistance to density remained strong, and developers continued to build outward rather than upward. But the technical argument had already been settled.
City Hall stood as living proof that:
- High-rise buildings could be engineered safely in Los Angeles
- Earthquakes were a challenge, not a barrier
- Fire, structural, and seismic risks could be managed
The height restriction was no longer about safety — it was about philosophy.
The Ironic Legacy
When Los Angeles finally lifted its height limit in 1957, the city did not suddenly erupt into skyscrapers. The habit of building outward was already deeply entrenched.
The result:
- A skyline that arrived decades late
- Uneven density across the region
- Multiple business centers instead of one core
- Housing and transit challenges baked into the city’s growth pattern
City Hall never triggered a skyscraper boom — but it quietly made one possible.
Why This Still Matters
Today, Los Angeles continues to wrestle with:
- Housing shortages
- Transit-oriented development debates
- Height and zoning battles near rail corridors
- Resistance to density in a growing city
These debates didn’t begin recently.
They trace back to a single contradiction: a city that banned tall buildings — while proving they could be built safely all along.
Los Angeles City Hall wasn’t just a monument.
It was a test case — and it passed.

Community
Local governments provide proof that polarization is not inevitable
Local politics help mitigate national polarization by focusing on concrete issues like infrastructure and community needs rather than divisive symbolic debates. A survey indicates that local officials experience less partisanship, as interpersonal connections foster recognition of shared interests. This suggests that reducing polarization is possible through collaboration and changes in election laws.
Lauren Hall, Rochester Institute of Technology
When it comes to national politics, Americans are fiercely divided across a range of issues, including gun control, election security and vaccines. It’s not new for Republicans and Democrats to be at odds over issues, but things have reached a point where even the idea of compromising appears to be anathema, making it more difficult to solve thorny problems.
But things are much less heated at the local level. A survey of more than 1,400 local officials by the Carnegie Corporation and CivicPulse found that local governments are “largely insulated from the harshest effects of polarization.” Communities with fewer than 50,000 residents proved especially resilient to partisan dysfunction.
Why this difference? As a political scientist, I believe that lessons from the local level not only open a window onto how polarization works but also the dynamics and tools that can help reduce it.
Problems are more concrete
Local governments deal with concrete issues – sometimes literally, when it comes to paving roads and fixing potholes. In general, cities and counties handle day-to-day functions, such as garbage pickup, running schools and enforcing zoning rules. Addressing tangible needs keeps local leaders’ attention fixed on specific problems that call out for specific solutions, not lengthy ideological debates.
By contrast, a lot of national political conflict in the U.S. involves symbolic issues, such as debates about identity and values on topics such as race, abortion and transgender rights. These battles are often divisive, even more so than purely ideological disagreements, because they can activate tribal differences and prove more resistant to compromise.
Such arguments at the national level, or on social media, can lead to wildly inaccurate stereotypes about people with opposing views. Today’s partisans often perceive their opponents as far more extreme than they actually are, or they may stereotype them – imagining that all Republicans are wealthy, evangelical culture warriors, for instance, or conversely being convinced that all Democrats are radical urban activists. In terms of ideology, the median members of both parties, in fact, look similar.
These kinds of misperceptions can fuel hostility.
Local officials, however, live among the human beings they represent, whose complexity defies caricature. Living and interacting in the same communities leads to greater recognition of shared interests and values, according to the Carnegie/CivicPulse survey.
Meaningful interaction with others, including partisans of the opposing party, reduces prejudice about them. Local government provides a natural space where identities overlap.
People are complicated
In national U.S. politics today, large groups of individuals are divided not only by party but a variety of other factors, including race, religion, geography and social networks. When these differences align with ideology, political disagreement can feel like an existential threat.
Such differences are not always as pronounced at the local level. A neighbor who disagrees about property taxes could be the coach of your child’s soccer team. Your fellow school board member might share your concerns about curriculum but vote differently in presidential elections.
These cross-cutting connections remind us that political opponents are not a monolithic enemy but complex individuals. When people discover they have commonalities outside of politics with others holding opposing views, polarization can decrease significantly.
Finally, most local elections are technically nonpartisan. Keeping party labels off ballots allows voters to judge candidates as individuals and not merely as Republicans or Democrats.
National implications
None of this means local politics are utopian.
Like water, polarization tends to run downhill, from the national level to local contests, particularly in major cities where candidates for mayor and other office are more likely to run as partisans. Local governments also see culture war debates, notably in the area of public school instruction.
Nevertheless, the relative partisan calm of local governance suggests that polarization is not inevitable. It emerges from specific conditions that can be altered.
Polarization might be reduced by creating more opportunities for cross-partisan collaboration around concrete problems. Philanthropists and even states might invest in local journalism that covers pragmatic governance rather than partisan conflict. More cities and counties could adopt changes in election law that would de-emphasize party labels where they add little information for voters.
Aside from structural changes, individual Americans can strive to recognize that their neighbors are not the cardboard cutouts they might imagine when thinking about “the other side.” Instead, Americans can recognize that even political opponents are navigating similar landscapes of community, personal challenges and time constraints, with often similar desires to see their roads paved and their children well educated.
The conditions shaping our interactions matter enormously. If conditions change, perhaps less partisan rancor will be the result.
