Announcing a New Specialty Group at AAG: Critical Islands, Archipelagos, and Oceans (CIAO)

From CIAO founding members Meagan Harden, Marina Karides (Chair), Neha Kohli, and Emily Mitchell-Eaton

We are thrilled to announce the launch of the AAG’s newest specialty group, Critical Islands, Archipelagos, and Oceans (CIAO). CIAO is a scholarly and activist community committed to advancing the study of islands, archipelagos, and oceans as lived spaces and geographic forms enabling for critical thought. In the present moment of environmental injustice, capitalist failure, and the enduring realities of colonialism that work to divide us, we are dedicated to building solidarities across—and through—oceanic space.

CIAO’S vision

We envision CIAO as a dynamic space for geographers, Islanders, and others committed to social justice to convene in the co-creation of knowledge specific to islands, archipelagos, and oceans. In this spirit, we invite diverse perspectives that adopt a critical lens to interrogate the following topics:

  • Migration, mobility, and transoceanic networks
  • Archipelagic relationalities
  • Indigenous sovereignty
  • Island economies
  • Oceanic borders, territorialities, and governance
  • Responses to climate change
  • Militarism and militarization
  • Island feminism and island-based social movements
  • Indigenous futurisms

These topics are starting points rather than constraints and we welcome scholarly engagement beyond these themes.

CIAO’S activities

Upon joining CIAO, members can look forward to the following activities:

  • Virtual and in-person networking opportunities
  • Professional development and peer mentoring
  • Student travel grants
  • Awards for outstanding papers and creative scholarship
  • Conference activities at the AAG Annual Meeting including paper/panel sessions, social gatherings, and organized field trips.
  • At AAG 2026, CIAO will sponsor:
    • A session titled “Island Feminisms: Anti-racist and Decolonial Scholar-Activist Solidarities for Social and Environmental Justice/Feminismos isleños: solidaridades antirracistas y decoloniales entre académicas/os activistas por la justicia social y ambiental”
    • A panel
    • Any relevant sessions that AAG members suggest!

CIAO’S commitments

As a Specialty Group that explicitly recognizes the colonial legacy of the geography discipline, as well as the myriad ways that academia reinforces social, political, and economic inequalities, CIAO is committed to building an inclusive space safe from discrimination and violence. In addition to the professional benefits of CIAO membership, CIAO is committed to:

  • Celebrating and amplifying the voices of Islander and coastal communities; Indigenous peoples, women, people of color, and other marginalized communities
  • Upholding academic freedom within CIAO activities;
  • Facilitating transparent and accountable governance; and
  • Aligning with the AAG’s ethics of care for creating safe space at AAG Meetings, its Statement of Professional Ethics, and Professional Conduct Policies and Procedures

By Emily Frisan

The world will have to feed 10 billion people by 2050. For the past 60 years, agricultural production has been driven by management of labor, technological advancements, and the expansion of irrigated areas. In the United States, the rise of single-crop farming became more intense in the early 20th century. It powered a larger scale of production so we could feed a rapidly increasing global population. Despite this, over 735 million people worldwide still go to bed hungry each night.

The world’s agricultural land can be divided into two basic categories: cropland and land for livestock (pastureland). As of 2020, both of these cover 32 of the world’s total land area. That’s nearly 8% growth since 1961. Farms and pastures cover 40 of all habitable land in the world, about 4.2 billion hectares.

The immense agricultural space and over 14,000 edible plant species should mean more diversified food choices. Yet 75% of the world’s food comes from just twelve plant species and five animal species. Wheat, corn, and rice together provide nearly half of the world’s plant-derived calories. These major crops are often grown at large scales as “monocultures:” a single crop grown alone in large fields.

Where the World’s Food Grows

Before European colonization, thousands of ecosystems, species of plants, and animals thrived in regions worldwide. Agriculture was more local. Communities were rooted in local traditions for caring for land and growing food. Today, these major food-producing regions include Africa, Asia, and parts of North and South America.

The Global North and Global South are terms used to group countries based on their wealth and development. These categories are sorted to understand differences in how countries are similar economically and politically. Typically, the Global South countries’ economies depend on shipping out agricultural products and raw materials. While crops are grown worldwide, in 2020, the Global South accounted for 73% of agricultural production across the world. This has increased 33% since 1961.

Crops and livestock vary in different geographic regions. This might be due to climate, native species, or economic and cultural significance. For instance, the United States is a major producer of corn and soybeans. Countries like India and China are producers of rice and wheat. Explore this interactive map to learn about where your food comes from — past and present.

Old Techniques for New Growth

Feeding the world’s people is not as easy as expanding farmland. That would come at the cost of forests and other ecosystems. This further contributes to biodiversity loss and climate change. Agriculture is a leading cause of habitat loss, using 70% of global water use and releasing over 25% of the earth’s greenhouse gas emissions. Increasing agricultural productivity without using more land is essential. It is being lost to urban sprawl, erosion, sea level rise, change in climate, and chemical pollution.

An answer to these growing problems includes looking to Indigenous agriculture management systems. These practices include a wide range of techniques. For example, intercropping is used with multiple species of plants, such as the Three Sisters (corn, beans, and squash). Crop rotation is used to preserve soil health. Also, farmers can burn certain sections of the forest to clear the land for agriculture and encourage “interspecies synergies” where animals benefit from working together.

Once set aside by Western water managers, traditional irrigation practices like the “acequia system” can improve water quality using physical geography. Gravity carries water downhill. This slowly distributes minerals and rich soil throughout the landscape. Acequia developed from Native people’s experiences farming in the Southwest United States. The Acequia Institute in San Luis, Colorado, is one organization that is working to bring back traditional farming practices. They hope to revive Indigenous methods that work with natural water systems to introduce a closer connection of food and nutrition to the community.

North American Beavers in South American Forests?

By Cadence Bowen

Patagonia, a remote region at the tip of South America, has some long-distance intruders. In 1946 the North American beaver (Castor canadensis), was brought here. Its population has thrived—to the dismay of local humans.

The story of beavers in Patagonia shows how humans can introduce invasive species. These are non-native species which can overrun native species. This often causes an imbalance in the ecosystems in these environments. The problem of invasive species is driven by human interests, such as commercial or agricultural use of animals or plants.

North American beavers were almost wiped out in their native habitats by 1900. They were saved through intense conservation. Ironically, in Patagonia the focus is how to get rid of them. The Wildlife Society’s Pablo Jusim says, “Technically, it’s viable to eradicate beavers from South America—one of the biggest eradications in the world if we achieve it.” He estimates a cost of about $31 million and 20 to 30 years to eliminate Patagonian beavers and restore ecological balance.

Well, How Did They Get Here?

Imagine the southernmost part of South America: that’s Patagonia. Part of both Chile and Argentina, Patagonia is known for its diverse geography. Snowy mountains and lush forests in the west are answered by steppes and deserts in the east. The archipelago of Tierra del Fuego is at the tip of this area. It has its own diverse and rugged terrain, from lowlands and glaciated coasts in its north to high mountains in the east.

In 1946, the Argentine government introduced just 20 North American beavers to Tierra del Fuego. The intention was to kickstart a fur trade for pelts. Officials believed the climate would be similar enough to the beavers’ native climate to suit them. Little thought was given to native trees, plants, and ecosystems. The trees and forests of North America co-evolved with beavers and can take their energetic tree felling and dam building. The native forests of Tierra del Fuego had never experienced anything like this. Plus, beavers have no natural predators in Tierra del Fuego. Eighty years later, the species’ population is more than 150,000, almost outnumbering human inhabitants.

Impacts of these “Ecosystem Engineers”

Beavers are ingenious animals with the ability to alter the landscapes they inhabit. These furry creatures are admired for their important roles in North America, both their contributions to river ecologies, and their earlier pivotal role in the fur trade of early America. They shape the environment more than any other species besides humans. Kodi Jo Jaspers, manager of the Wenatchee Beaver Project in Washington State, calls them “ecosystem engineers.”

When beavers build dams in North America, they create habitat for a lot of different species. This can help address the impacts of climate change by retaining groundwater, absorbing rain, and stopping or slowing the spread of wildfires.

Beavers’ impacts in North American ecosystems don’t translate well to the South American islands of Tierra del Fuego. They have become destructive toward its pristine forests and rivers. They lack the natural predators that North American beavers face, such as bears, wolves, and coyotes. Their natural behavior—gnawing trees and building dams—causes the roots of the remaining trees to rot in the saturated soil. Eventually, these trees to die. The river systems and watersheds that support life on the islands are filled with dead flora and sediment.

“I admire the animal actually. … How it works with the rivers, how it is adapted, how they molded nature for their own benefit, builds his house, his dams. ”

—Pablo Kunzle, Interviewee in Beavers: Patagonia Invaders

Is there a future Patagonia without beavers?

The 2015 documentary, Patagonia Invaders, highlights the community response to Tierra del Fuego’s beavers. From trendy fur coats to beaver tenderloins, locals have taken unusual steps to reduce the numbers of these invasive critters and their continuing impacts.

A study in the 1990s showed they had colonized about 94% of the rivers in the archipelago. Peacefull population control measures had limited results. In 2015, the Argentine government began a three-year eradication project. They applied the toughest means: full-body traps and hunting. The approach was successful enough for The Wildlife Society to recommend a larger-scale approach.

Researcher Mara Dicenta coined the term “Beavercene” to describe the changed landscape of Tierra del Fuego since 1946. She views the introduction and attempted eradication of beavers there as two ends of the same spectrum, caused by “a history of colonial interventions that ignore local environments.”

The latest approach to managing beavers in Tierra del Fuego’s forests might result in harmony or further destruction. In a fragile place that is out of balance, that question still hangs in the balance.

The Geography of Bison: Returned from the Brink

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!!

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!

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.
