The American bison, commonly known as the buffalo, is an icon of the U.S. “Wild Wild West.” The wild American bison was a major food source for native Americans for thousands of years. Yet, by the 1900s, it had been hunted to near extinction by settlers, trappers, and hunters,

The bison is the largest animal native to North America. Males weigh up to a ton (2,000 lb or 1,000 kg). At the turn of the century, there were only reportedly 23 wild bison left inside the territory of Yellowstone National Park and perhaps only a few hundred or so more scattered elsewhere in the U.S. and Canada.

In attempts to salvage the species, governments, organizations, and individuals made efforts to save a few bison. Those few in Yellowstone were successfully protected and became a core of the revival of a herd whose numbers rebounded rapidly. Other captured bison were protected by enterprising farmers and agencies, some on small farms and others as the beginnings of small herds. All of these actions saved the bison’s genetic profile from extinction.

The bison is a hardy creature, able to withstand extreme temperatures, heavy snow, drought and onslaughts of most predators. The bison’s size, herding instincts and aggression help ward off wolf packs and bears, the animal’s main threats. Accord to the National Bison Association, there were 1,986 bison ranches and farms in the U.S. in 2022.

Several issues still plague the bison from reviving to historic numbers. First of all, the territories available for wide-ranging herds of wild bison are very limited. Fences must be very strong and/or electrified to usually contain them, but even the strongest fencing cannot always contain bison, particularly large males. Private herds must be constantly managed. Although a large bison bull can literally run through fences when frightened, more “escapes” are caused by mating instincts where several males will push through their containing fences en masse to reach a female in estrus (ready to breed).

When they escape their containment as on bison farms surrounded by fences, bison are very hard to retrieve. They often require tranquilizer shots to neutralize their natural aggressiveness. Unlike cattle that can be rounded up with help of dogs, bison are almost immune to that process, sometimes only responding to food (grain) to lead them back into confinement.

Whereas bison escapes are mostly associated with bison farms and smaller ranches, the unfenced 4,900 bison in Yellowstone’s free-ranging herd are unconfined, which brings a new and different problem. When these bison leave the Park, they range onto surroundings under private ownership and National Forest Services land. Thus, they may cause jurisdictional problems, whereby they enter private grazing land and cropland, tear down farmers’ fences, damage farm equipment, destroy delicate ecosystems, and harass farm animals. Once on private land, they are unprotected and exposed to hunters and highway vehicles.

There are an estimated 400,000 bison in the United States, including 31,000 in conservation-focused facilities (parks and Tribal Lands), and the rest on bison farms and ranches. The Native Lands Advocacy Project (NALP) estimates that bison numbers overall increased at a rate of 13.36% between 2012 and 2017, while Tribal bison increased by 1031%. Clearly, Native Americans’ reverence for bison has enhanced the reproductive and survival rates among the herds under their care.

So what is the geographic distribution of bison in the United States today? Every state except the smallest East Coast states contains some small bison farms and larger

ranches. Most of the bison are raised as food, with the market prices for ground bison being three to five times more costly than beef. Consequently, commercial bison meat is mainly marketed to high-end restaurants and advertised as a healthy specialty item.

The word is out: Bison are BACK!!

And that is Geography in the News, updated October 1, 2025.

AAG’s Geography in the News is inspired by the series of the same name founded by Neal Lineback, professor and the chair of Appalachian State University’s Department of Geography and Planning. For nearly 30 years from 1986 to 2013, GITN delivered timely explainer articles to educators and students, relevant to topics in the news. Many of these were published on Maps.com’s educational platforms and in National Geographic’s blogs. AAG is pleased to carry on the series.

The Hills of San Francisco

Street hill gradient in San Francisco

Unlike the rest of California, San Francisco has a unique geography that shapes its weather and settlement patterns. The city is set on the tip of a peninsula halfway up the coast of northern California, surrounded by bodies of water on three of its sides: the Pacific Ocean, the Golden Gate strait, and the San Francisco Bay. The city is laid out over hills that stretch from coast to coast, reaching heights of nearly 1,000 feet, making the climate similar to coastal areas on the Mediterranean.

The hills of San Francisco define its topography and culture. It’s hard to pinpoint the exact number in the city, but many sources consider there to be more than 50 named hills. As Pulitzer Prize-winning San Francisco Chronicle columnist Herb Caen notes in his introduction to the Hills of San Francisco, no one can quite agree on which [hills]. Although it’s debated among locals, there are seven hills that are iconic to the city: Russian Hill, Nob Hill, Telegraph Hill, Twin Peaks, Mount Davidson, Mount Sutro, and Rincon Hill.

So, when is a hill a hill? Self-proclaimed San Francisco explorer Dave Schweisguth claims, “When it’s a lone mountain. That is, if you can walk all the way around it, always looking up to its summit. It’s not so clear cut when hills run together into a ridge, which most of San Francisco’s do. Height alone is not so important: a very small hill may be perfectly obvious, while a string of higher summits may be hard to tell one from the next. It’s easier to call a hill a hill if it’s separated from its neighbors — if, on a topographic map, a contour line or two traces all the way around its summit.”

The Range of Iconography

Originally named Blue Mountain for the wildflowers that cover the hillside, the city’s tallest hill was renamed Mt. Davidson at the urging of the Sierra Club in 1911, after George Davidson, the geographer who surveyed it. It is the focal point of San Francisco’s Mt. Davidson Park, with a forest that accounts for more than 30 of the park’s acres, quietly remaining an oasis in the most densely settled city in California. Defined by a 100-foot cross at its peak, Mount Davidson stands at an elevation of 928 feet. Urban hikers share that despite how small the overall area is, the trails aren’t consistently marked, which causes explorers to get lost in the woods.

Hikers also recommend Mount Sutro, located in central San Francisco, for its role in the city’s cultural and natural history. Its century-old trails are now preserved by the University of California, San Francisco, which guides the long-term restoration of the 61 acres and protects the ecological oasis in the heart of the urban environment, along with the citizen group Sutro Stewards. The city’s elevation and abundant summer fog contribute to the mountain’s microclimates and its plant and wildlife communities.

Originally called “Los Pechos de la Choca” (Breasts of the Maiden) by early Spanish settlers, Twin Peaks is a main landmark of San Francisco’s skyline, reaching elevations of 910 and 922 feet. Similar to Mt. Davidson and Mt. Sutro, Twin Peaks hosts a 64-acre park of coastal scrub and grassland communities that offer an idea of how San Francisco’s hills and peaks looked before development changed them forever.

Early in defining San Francisco’s history, Nob Hill, Russian Hill and Telegraph Hill continue to remain among the most popular neighborhoods to visit.

Russian Hill’s name dates to 1847 when Russian sailors were buried on the hill during the gold rush in the 1800s. The burial sites are long since deeply covered, and it’s now only possible to admire a plaque at the site where the cemetery once stood. This is the same neighborhood home to the famous Lombard Street, that draws tourists from around the world due to its scenic switchbacks and postcard views. Because the slope in this area reaches 27° (51%), 8 hairpin bends were put in the 1300 feet between Hyde Street and Leavenworth Street to allow cars to drive down the street, ultimately creating one of the most winding streets in the world.

Russian Hill borders Nob Hill to the south, one of the city’s most upscale neighborhoods.  Originally called California Hill (after California Avenue, which runs right over it), Nob Hill got its name from the word “nabob” that originated from the Hindu word meaning a wealthy or powerful person. This affluent neighborhood was home to the Central Pacific Railroad tycoons known as the “Big Four,” who were among the first to build their mansions here.

Telegraph Hill hosts Coit Tower, an iconic piece of architecture that resembles a fire hose and affords incredible views of the city; its walls are also home to historic artwork. Originally, the Tower was a windmill-like structure created in 1849 to signal ships entering the Golden Gate. Once the trek is completed, the summit provides a breathtaking panoramic view of the city with landmarks like the Golden Gate Bridge, Alcatraz, and the Transamerica Pyramid.

Whether you’re taking a leisurely stroll or hiking the steepest routes, you can recall the words of the iconic San Francisco journalist Herb Caen, who once said, “Take anything from us — our cable cars, our bridges, even our Bay — but leave us our hills.”

You can hit the trails with a guided tour or explore the city on your own. The SF Gate compiled a list of 11 hikes within the city limits that allow visitors and residents to get to know the landscape. An interactive map created by a UC Berkeley graduate student studying urban planning maps SF’s slopes and uses simple color coding to show where the flattest pockets of land are. If you’ll be attending AAG’s 2026 Annual Meeting in San Francisco, you’ll want to bring your walking shoes!

Brian Berry

On January 2, 2025, Dr. Brian Berry passed away at the age of 90. Renowned for his influential work in urban and regional research, he was also a past AAG president (1978-79).

Berry was born in Sedgely, Staffordshire, United Kingdom on February 16, 1934. He graduated from University College, London, with a B.Sc. in Economics with first class honors in 1955. He was a Fulbright scholar at the University of Washington, where he completed an M.A. in 1956, and a Ph.D. in 1958, studying under noted geographer and leader of the quantitative revolution, William Garrison, in the Department of Geography.

Upon completing his Ph.D., he began his career, which spanned more than six decades. In 1958 he was named the Irving B. Harris Professor of Urban Geography, chairman of geography and director of the Center for Urban Studies at the University of Chicago. Berry’s early spatial analytic research helped spark the scientific revolution that occurred in geography and urban studies in the 1960s, making him the world’s most frequently cited geographer for more than 25 years. He refined the concept of “central place theory” and laid the foundations of analytic urban geography, spatial analysis, and of geographic information science.

In 1975, Berry was the youngest social scientist ever elected to the National Academy of Sciences. He subsequently was named a Fellow of the American Academy of Arts and Sciences and of the British Academy. From 1976 to 1981, Berry joined Harvard University where he served as the Frank Backus Williams Professor of City and Regional Planning, chair of the Ph.D. Program in Urban Planning, director of the Laboratory for Computer Graphics and Spatial Analysis, and a faculty fellow of the Institute for International Development. He was appointed University Professor of Urban Studies and Public Policy and dean of the Heinz College at Carnegie Mellon University, until he joined the University of Texas at Dallas (UTD) in 1986.

At UTD, Berry became the first director of the Bruton Center for Development Studies. In 2005, he was appointed dean of what was then the School of Social Sciences before he engineered its transformation into the School of Economic, Political and Policy Sciences (EPPS).

Among his many accolades, Berry was the 1978-79 President of the Association of American Geographers. In 1988, he was also awarded the Victoria Meda, the Royal Geographical Society’s highest honor, and the Vautrin Lud Prize — considered the “Nobel Prize for Geography” — in 2005. He also earned the Kondratieff Medal from the Russian Academy of Sciences in 2017 and the Stanley Brunn Award for Creativity in Geography from the American Association of Geographers in 2020. Most recently, in 2021, Berry earned the University Consortium for Geographic Information Science Research Award. The award recognized Berry’s early research on geographic information systems — specifically his conceptualization of the geographic matrix in 1964 — that continues to shape practice and to ensure conceptual and functional linkages between geographic information science technique and the field’s intellectual core.

Although Berry authored over 550 books and articles, he is most proud of being the advisor to more than 150 Ph.D. students and has served on an equal number of other doctoral committees. Many of his students have gone on to successful academic and professional careers in their own right.

He also has been an active family historian and genealogist, with many additional publications to his name, most recently delving into genetic genealogy. Brian retired from active academic life to become a “gentleman rancher” in 2020. Brian is survived by his wife, Janet (Shapley) Berry; son, Duncan J. Berry; and daughter, Diane Berry Yakel.

Ross MacKinnon

Ross MacKinnon, scholar and administrative leader at UConn, SUNY-Buffalo, and the University of Toronto, passed away from pancreatic cancer at his home in Sonoma, California, surrounded by family, on Jan. 27, 2025, at the age of 82.

As a geographer, he was well-versed in the development of mathematical models for geographical systems, and he made particular contributions to geography through the application of these models to the fields of transportation and migration.

Ross grew up in New Westminster, Trail, and Kelowna, British Columbia. He earned a bachelor’s degree in geography from the University of British Columbia in 1964. He was a Woodrow Wilson Scholar, earning a Master of Science in geography from Northwestern University in 1966, and a Ph.D. in geography from Northwestern University in 1968. He was a faculty member of the University of Toronto’s geography department, where he became a Director of Graduate Studies. He joined SUNY-Buffalo in 1976 as Chair of the geography department and later became Dean of Social Sciences. He joined UConn as Dean of the College of Liberal Arts and Sciences in 1996 until he retired in 2008. He championed major investments in hiring, research, academic programing, and most importantly … people.

From Dr. Peter A. Rogerson, one of Dr. MacKinnon’s advisees at SUNY-Buffalo:

Ross MacKinnon was my Ph.D. advisor, and I’ll begin by literally “turning back the clock.”  Somewhat more than midway through my dissertation defense, I made a statement to the effect that I was running out of time. Ross immediately got up, went over to the wall clock, and turned the hand back ten minutes. That is just a small story hinting at the many ways that he showed his support over the years. He was proactive when it came to students and recruitment — while I was taking a gap year after doing my M.A. with him at the University of Toronto, he wrote to me, convincing me to do my Ph.D. at Buffalo, where he was beginning to build the department in his new role as Chair. During my first AAG, he and I split the presentation of our joint paper. Aside from recalling how much my knees were shaking, I can now recall all of his colleagues he introduced me to — and although I didn’t have a clue at the time, I now recognize how this was one of the most important moments in my career. Over time I saw the time he spent with students, the care he took with them, and how important his mentorship was to their careers. A long line of his students and eventual professors went on to have very successful careers.

One of his traits that I always marveled at was his ability to “cut to the chase.”  As a student this took the form of his knowing precisely what to ask a student.  He knew what you didn’t know and needed to know, and he was unequaled in asking exactly the right question at the right time, to push you a little further. Later on, when I saw him in his roles as Chair and Dean, this took the form of sizing up both current and prospective faculty.  He simply had an uncanny knack for seeing precisely how both personality and talent could or could not contribute to a department or program.

He saw to all aspects of a department — seeing to it that we not only had excellent personnel, but a vibrant social life with picnics, happy hours, and the like. Oh, and by the way, at one of those department picnics, while playing the outfield in the annual softball game, I tried to gun down a runner at second base.  When I started my throw, I forgot that Ross was playing second base, and it was only while the ball was in mid-flight that I realized I should have made a softer throw. My last recollection was going to some emergency room or urgent care to see how his fingers were doing and thinking that this was not a good thing to do to your advisor.

Shortly before I arrived at Buffalo, budget cuts in the SUNY system led to very serious consideration of eliminating the department.  It is difficult to capture here, but his efforts were absolutely crucial and pivotal in keeping the department alive.

He was also central to putting the department on the road to prominence (and in fact it would not be an exaggeration to say that he did this single-handedly). Part of this was attributable to his vision and his judge of talent and promise, and part was due to his vision of, and his work toward a successful bid to bring the National Center for Geographic Information and Analysis (NCGIA) to Buffalo.

Ross MacKinnon was a “quick study” when it came to sizing up people’s academic potential, their personalities, and their current or potential contributions to a department or program. His sharp wit and sense of humor gave him the ability to make lightning-quick comments about how someone could or could not help a program, might or might not become a star in the discipline, etc. Listening to his evaluations often left one both laughing at the humor and impressed with his assessment, as well as being in awe of how he could combine the two so quickly. All of this made him a fantastic mentor, colleague, Chair, Dean, and friend.

Ross was a proud Canadian and naturalized U.S. citizen. He loved travel, a good meal with friends, live jazz, contemporary painting, new plays, his dog, and the Buffalo Bills. He had a great sense of humor and was quick with encouragement.

He is survived by his wife, Marilyn Hoskin, and his two daughters, Pam and Caroline MacKinnon.

Sowing the Seeds for Food Sovereignty in Detroit

Urban agriculture is blossoming in Detroit, gaining recognition for its “green revolution,” through the rise of urban gardens and farms. With a total of 139 square miles or over 100,000 empty lots being vacant, this provides an opportunity to incorporate green spaces into communities throughout the city.

Urban gardening isn’t new to Detroiters. During the economic crisis of 1893, “Potato patches” helped feed hungry families and taught people how to grow their own food during times of social and economic crises. Later, in the 1970s, Mayor Coleman Young’s “Farm a Lot” program set an ambitious goal of transforming 3,000 empty lots into urban gardens. In the late 1960s the Black Panther party served breakfast to children in Black communities — highlighting the racialized gaps in funding from the United States government. The connections among community, mutual aid, and growing and providing food go far back in Detroit. Rather than working against each other, cooperatives and mutual aid programs ensure that groups can pull resources together to beat the system at its own game.

Detroit’s history of gardening, farming, and giving to neighbors shows how communities can move beyond food justice and into food sovereignty. Food justice addresses hunger at a basic level; food sovereignty takes it up a level to define, own, and dictate a food system. This in turn provides the earth with increased resilience to crises and climate impacts, in addition to promoting autonomy for communities. According to shakara tyler, co-executive director of the Detroit Black Community Food Sovereignty Network, part of creating a just society and systems means, “shifting from extractive economy and reinvesting into the regenerative economy.”

The growth of urban agriculture in Detroit is a testament to the resilience and innovation of its people. Initiatives such as the Oakland Avenue Urban Farm and Detroit Black Community Food Sovereignty Network are prime examples of how community-based organizations can catalyze change, serving as educational platforms for sustainable living. Explore gardens and organizations below to see how modern food sovereignty is inspiring Detroiters to create a deep praxis within other justice movements across local and state-wide levels.

Michigan Urban Farming Initiative

7432 Brush St, Detroit, MI 48202

Based in Detroit’s North End community, Michigan Urban Farming Initiative’s (MUFI) redevelopment of a three-acre area in Detroit’s North End, is being positioned as an “epicenter of urban agriculture.” With the goal of creating a sustainable “agrihood” with multiple projects, the campus is divided into thirds: production farming, interactive agriculture, and hardscaped spaces, such as their Community Resource Center. Since operating out of their new headquarters, MUFI has been able to grow and distribute over 50,000 pounds of produce (grown using organic methods) to over 2,000 households within 2-square miles at no cost to the recipients.

Oakland Avenue Urban Farm

9227 Goodwin St, Detroit, MI 48211

Operating out of Detroit’s North End neighborhood since 2010, the Oakland Avenue Urban Farm (OAUF) is “cultivating healthy foods, jobs, and active cultural spaces.” The “Farm” grows over 33 varieties of vegetables and fruits and operates a “Harvest on Demand” option with local farmers markets, allowing neighbors to have consistent access to produce. In addition to partnering with local chefs and nonprofits to distribute tens of thousands of hot meals across the city, OAUF provides training opportunities, manages a community land trust, and brings together youth to improve learning and leadership skills.

Keep Growing Detroit

1445 Adelaide St, Detroit, MI 48207

Keep Growing Detroit (KGD) is working to cultivate a food sovereign city where the majority of fruits and vegetables consumed by Detroiters are grown by residents within the city’s limits. Their Garden Resource Program (GRP) supports urban gardening in the city by providing high-quality resources to family, community, school, and market gardens located in Detroit, Highland Park, and Hamtramck. Participants receive seeds, transplants, personalized garden assistance from staff, and a connection to an incredible network of gardeners, farmers, and advocates for a thriving food system across the city.

Detroit Black Community Food Sovereignty Network

11000 W Mcnichols Rd Ste 103, Detroit, MI 48221

Another non-profit that aims to amplify and create sustainable and equitable food systems is the Detroit Black Community Food Sovereignty Network (DBCFSN). The 7-acre urban “D-Town Farm” grows more than 36 different fruits, vegetables, and herbs with cultural and social significance, with the intention of farming what people want to eat and in high demand. Their work to shift the understanding of food, is a way to have sovereignty and learn about the importance of these systems. In addition to providing security, DBCFSN co-founded the Detroit Black Farmer Land Fund with KGD and OAUF to support rebuilding black land wealth. Since 2020, over 239 awards have been made to residents, businesses, and organizations.

North End Agri-Arts Alley

Currently under-going construction

In March 2023, the city announced four new Arts Alley locations in North End, Detroit. Specifically, the North End Alley will be the first Agri-Arts alley as part of a federal grant to transform dilapidated alleys into artistic oases. Anchored by the Oakland Avenue Urban Farm in partnership with artists from the Oakland Avenue Artists Coalition, this green alley will complement the Oakland Avenue Farmer’s Market, North End Resource Center, Oakland Avenue Cooperative Greenhouse, and Black Bottom Garden Center. Major construction is currently underway and is expected to be completed in late Spring 2025.

Urban farms and gardens are not just places to grow food; they are hubs of community activity, education, and empowerment. While the challenge remains to make these green spaces accessible to all, efforts are being made by the city to provide urban agriculture government guidance and infrastructure. In September 2023, the city of Detroit named Tepfirah Rushdan, former co-director of Keep Growing Detroit, its first director of Urban Agriculture. Over the past decade, the movement has seen substantial growth, transitioning from a few community gardens to a network of over 2,00 gardens and farms engaging nearly 20,000 Detroiters as of 2023.

The Hidden Costs of Commercial Fishing: Sustaining Economies and Ecosystems

Geography In The News logoGeography in the News is an educational series offered by the American Association of Geographers for teachers and students in all subjects. We include vocabulary, discussion, and assignment ideas at the end of each article. 

By Adeti Afe

Fishing has been a part of human life for thousands of years, helping to feed societies while maintaining a balance in marine ecosystems. Traditional fishing usually keeps fish populations in check. But now, methods for industrial-level commercial fishing can cause serious harm to marine ecosystems. Scientists warn that some of the world’s most important fishing areas and habitats could be permanently damaged due to issues like overfishing, habitat destruction, and the problems caused by aquaculture.

Overfishing disrupts the balance of marine life. When certain fish populations decline, predators lose their prey, and smaller fish can overpopulate. This creates even more problems in the ecosystem. Coral reefs, for instance, rely on fish to control the growth of algae. Without enough fish, algae can grow uncontrollably, killing the reef’s ecosystem.

The United Nations’ Food and Agriculture Organization (FAO) reports that more than one-third of global fisheries are overfished. Over the past 50 years, the number of overfished areas has tripled. A major factor contributing to this is bycatch, which is the unintentional capture of animals like sea turtles, dolphins, and sharks in fishing nets. Millions of animals are killed this way each year, adding to the damage in already struggling ecosystems. Sea turtles are often caught unintentionally by getting tangled in nets and are harmed before they can be freed. Similarly, endangered species such as certain whales and dolphins suffer high mortality rates due to poor fishing practices. Bycatch damages the biodiversity necessary for healthy ecosystems.

The methods used in industrial fishing often cause harm to underwater habitats. Bottom trawling, for example, involves dragging heavy nets along the seafloor. While effective at capturing fish, this practice devastates coral reefs and seagrass beds, which are essential habitats for many marine species.

The Complex World of Fish Farming

To meet the growing global demand for seafood, many businesses have turned to aquaculture, also known as fish farming. On the surface, aquaculture appears to be a solution to overfishing, but it introduces its own set of environmental and ethical concerns. Farmed fish are often raised in overcrowded enclosures, which can lead to water pollution from waste.

Aquaculture relies heavily on fishmeal and fish oil derived from wild-caught fish, which means it continues to put pressure on already overfished stocks. Escaped farmed fish can further disrupt ecosystems by competing with native species for resources or introducing genetic and behavioral differences that harm wild populations.

Finding a Better Way

The negative effects of commercial fishing extend beyond the environment, impacting human communities. Illegal, unreported, and unregulated (IUU) fishing increases the problem. Operating outside the bounds of international and local laws, IUU fishing often targets the waters of vulnerable nations. This practice robs local fishers of their resources and disrupts efforts to maintain sustainable fishing practices.

Several actionable steps can mitigate the damage caused by commercial fishing. Stricter regulations on fish catch limits and the establishment of marine protected areas (MPAs) can help ecosystems recover and maintain biodiversity. MPAs provide safe zones where marine life can thrive without the pressure of fishing.

Technological advancements can also play a role by including selective fishing gear that can reduce bycatch. Consumers can make a difference by choosing sustainably sourced seafood, certified by organizations such as the Marine Stewardship Council (MSC).

Commercial fishing is essential for feeding millions of people around the world, but it comes at a cost. Our oceans, and the communities that depend on them, are under serious pressure from overfishing, habitat destruction, bycatch, and unsustainable fish farming. These practices are pushing marine ecosystems to their breaking point. The good news is that we still have a chance to make a difference. By enforcing smarter regulations, using better technology, and making informed choices as consumers, we can create a fishing industry that works well with the environment. If we act now, we can protect the health of our oceans and ensure they continue to provide for generations to come.

Edward Babin

Dr. Edward Babin, a long-time professor at the University of South Carolina, Upstate (USC), died Sunday, March 5, 2023, in Spartanburg, SC.

He received his B.A. degree from the University of Louisiana, Lafayette in 1965, a master’s degree in Geography from the University of Arkansas in 1967, and a Ph.D. in Geography from the University of Georgia in 1974.

He taught geography at the University of Louisiana, Lafayette from 1968 to 1973. Dr. Babin joined USC Upstate as Professor of Geography from 1974 to 2015. He served as chair of the department twice.

Ed was born on August 29, 1944, the only child of Clarence and Helen Ourso Babin in Donaldsonville, LA.

Ed married Joanne Tinie Walsh on March 18, 1989, at Jesus, Our Risen Savior Catholic Church and was her devoted husband. They had no children. After marrying, Ed and Joanne became members of St. Paul the Apostle Catholic Church where Ed was an usher there for many years. He greeted parishioners at the door at both daily and Sunday Masses and enjoyed this ministry more than any other service he performed in the church.

In about 2013, Ed also started the senior singles’ luncheon for parishioners who found themselves single for one reason or another. This became a great place for newcomers to the parish to meet longtime members.

Ed became a professed member of the Secular Franciscan Order on April 5, 1995, which was a lifetime commitment to an international lay religious order in the Roman Catholic Church. He was a member of the St. Michael the Archangel Fraternity and served as its first minister for two terms.

Ed was an avid reader on many geographical topics and loved to discuss these with others. He had a dry sense of humor and a quick wit and loved to tell jokes and stories. He loved pets and had many special dogs and two cats in his lifetime. Among the dogs were Angel, Pepita, and Pixie, whom he loved to walk with through the neighborhood and greet the neighbors.

He grew tomatoes in his garden for many years and gave away tomatoes to others generously. He did his own yard work and earned “Yard of the Month” in the Forest Hills Neighborhood Association several times.

In addition to his wife, Joanne, Edward is survived by his cousins, Jay Landry (Verlein) of Donaldsonville, LA, and “Sport” Le Blanc (Cacki) of Baton Rouge, LA; siblings-in-law, Marilyn Walsh (Ed Laskarzewski) of Glastonbury, CT, William “Bill” E. Walsh (Winnie), Marshall T. Walsh (Debbie), and Sara O. Walsh, David L. Walsh, all of Spartanburg, SC, and Natalie W. Bishop of Nashville, TN; along with many nieces and nephews. He was predeceased by a brother-in-law, T. Walsh.

John S. Adams

John S. Adams, or JSA to those who knew him, was an urban economic geographer at the University of Minnesota. As a researcher, he studied the relationships between housing markets and policy, land use, and transportation in North American metropolitan areas. As a teacher, he taught classes on urban economics, transportation and land use, geography of the Twin Cities, and regional courses on North America and Russia. As a mentor, he advised dozens of graduate students, supporting them through research assistantships, an openness to whatever topic they chose to study, and continuing to be a source of guidance well after graduation. As an administrator, he was happy to take his turn as Department Chair (multiple times), President of the AAG, the first director and later the associate dean of the Humphrey School of Planning, and wherever else he was needed.

While JSA’s academic studies began in economics, he, like so many of us, took a class in geography and was hooked. After finishing his Ph.D. at the University of Minnesota, he taught at Penn State for three years before returning to Minnesota, where he taught for an astonishing 37 years. He spent time at many other institutions as a visiting scholar during that time, including UC Berkeley, Bank of America world headquarters, Moscow State University, and the U.S. Military Academy. During this time, he investigated housing policy and economics across North America, as well as developing a history of the quantitative revolution in urban geography.

Much of his research focused on the Twin Cities, including the Transportation and Regional Growth Study, funded by the Minnesota Department of Transportation, the Metropolitan Council of the Twin Cities, and the Center for Transportation Studies — a somewhat unlikely coalition to support research in the social sciences but reflective of JSA’s integrative approach to understanding the world. He was keen on producing research that was relevant to policymakers and planners in the region — many of whom he also had as students. The Center for Transportation Studies on the University of Minnesota campus established an award in 2009 in his honor for graduate students in planning and public policy, reflecting his contributions to interdisciplinary collaboration and policy-relevant research.

JSA was endlessly curious about the world. He was always asking people to share their stories with him, whether it was where they were from, where their family was from, or what they were interested in. He taught his graduate students that one of the best ways to do research was simply to ask people what they did for a living or what they thought of something, especially when it came to people like government bureaucrats whose stories often weren’t told. Field work was also essential: part of graduate student orientation at Minnesota was a field trip around the Twin Cities led by JSA and Professor Judith Martin, introducing students to their new home through a geographic lens. His willingness to strike up a conversation with anyone was especially on display during the field courses that he led across North America, Europe, and Russia for graduate and undergraduate students, along with his dedication to service no matter where he might be:

On a 1995 field study to cities of the U.S. Midwest and Southeast, it had been another long day of studying urban structure and change. Nobody knew why JSA stopped the van in the left turn lane of a busy thoroughfare during afternoon rush hour and got out of the driver’s seat, until we saw him dragging a fallen streetlight over to the curb and out of the lanes of oncoming traffic. Horns were honking, people were gawking, and we were kind of concerned that he might get electrocuted. But the image was perfect — “Citizen Adams,” in his signature plaid short-sleeve shirt and khakis, taking charge of Nashville’s “crumbling infrastructure” and “apathetic citizenry.”

Last but not least, JSA cared deeply about the institutions of higher education and of geography, arguing that higher education helps build a healthy foundation for the future of our country. He was a strong advocate for regular participation in departmental life and contributions beyond research and teaching. He argued for regular attendance at weekly departmental colloquia, in part to be well informed on the state-of-the-art of geographic research, but also to connect with students and faculty across the department as well as visiting speakers. Similarly, he advocated regular attendance at both national and regional AAG meetings, to hear about cutting edge research but also to learn about the state of the discipline in other departments and as a whole. He enjoyed introducing current and former students to each other, keeping the network of Minnesota alumni active through in-person meetings and also his family newsletter (always sent via the USPS). His sense of humor, concern for students and colleagues, and deep commitment to service are as much his legacy as his research and teaching, for geographers across Minnesota and around the world.

This memorial was prepared by Julie Cidell, Professor and Department Head of the Department of Geography & GIS at the University of Illinois at Urbana-Champaign; and Laura Smith, Associate Professor in the Department of Geography at Macalester College.
