New High Line Bridge: A Safe, Ecological Connection

In midtown Manhattan, the street crossings surrounding the entrance to the Lincoln Tunnel were once some of the most challenging in the city. A mess of highway ramps, missing sidewalks, and concrete barriers made the corner of Dyer Avenue and 30th Street an area to avoid.

Now with a new $50 million elevated connector, pedestrians can safely move 30 feet above the intersections, using a 600-foot-long L-shaped bridge from the High Line to Moynihan Train Hall.

On their way, they can take a moment to experience a woodland landscape and a marvel of glulam wood engineering designed by landscape architects at James Corner Field Operations (JCFO) and architects and engineers at Skidmore, Owings & Merrill (SOM).

“This new and vital pedestrian walk connects Midtown to the High Line and the West Side with a heightened sense of drama, spectacle, and delight,” said James Corner, FASLA, founder and CEO of JCFO.

The connector links the High Line — which starts on Ganesvoort Street in the Meatpacking District and ends at Hudson Yards and the Jacob Javitz Convention Center on 34th Street — with the $1.6 billion train hall that opened in 2021.

The new pedestrian passage can be expected to be used by tens or even hundreds of thousands of people a year. Pre-Covid, the High Line saw eight million visitors annually; and the train station has already welcomed 700,000 travelers.

Like all complex NYC projects, the connector came out of collaboration among a slew of public, private, and non-profit organizations — Empire State Development, the Port Authority of New York and New Jersey, Brookfield Properties, and the Friends of the High Line.

This team states that the connector is part of a collective effort “to create safer, more enjoyable pedestrian access, connect people to transit, and seamlessly link public open spaces and other community assets in the neighborhood.”

And JCFO, which has designed the High Line since 2004, notes that the connector is just one of new access improvements for the elevated park. A street-level plaza at the edge of the park on 18th Street is in development, and additional spaces to integrate the High Line into the community could happen in the future.

Spanning 600 feet, the walkway is comprised of two segments — a 340-foot-long woodland bridge running east to west, and a 260-foot-long timber bridge going north to south.

The woodland bridge is an extension of the landscape of the High Line Spur, which veers east off the main route of the High Line for half a block at 30th Street. Connected soil beds built into the black steel structure support 60 trees, 90 shrubs, and 5,200 grasses and perennials.

“The trees [are] characteristic of an Eastern deciduous forest that will grow into a lush landscape for birds and pollinators, provide shade, and shield pedestrians from traffic below,” the team writes. Ninety percent of the landscape is comprised of native plants, selected to provide color year round and habitat.

The timber bridge rises above the stream of traffic coming out of the Lincoln Tunnel, using a truss structure to minimize its footprint on the ground.

Made of glulaminated Alaskan yellow cedar wood from British Columbia, Canada, the connector also advances more sustainable practices. The highly compressed wood layers sequester carbon, and construction of the beams released far less greenhouse emissions than a steel alternative.

“The selection of glulam was based on its numerous benefits: It is a sustainably-sourced building material that has a lower carbon footprint than concrete or steel, while still providing exceptional durability and strength. Additionally, it adds warmth and texture as a natural material, enhancing the pedestrian experience, and offering a modern take on New York’s historic warren truss railroad bridges and structures,” said Lisa Switkin, ASLA, senior principal at JCFO.

(Switkin explains that glulam has many potential uses for landscape architects. The same Alaskan yellow cedar glulam was also used in their Tongva Park in Santa Monica, California).

Where the two bridges meet, the team also created a small plaza that offers a “moment of pause” amid the cacophony of midtown. Instead of dodging traffic, one can sit and take in the vista.

“We’ve heard for years about how inhospitable these streets around the entrance to the Lincoln Tunnel felt for people in the community. Now, the connector will give our neighbors a safe, green, and inspiring pathway,” said Alan van Capelle, executive director of the Friends of the High Line.

The Opportunities of Decarbonization

Architecture 2030 states that the built environment generates 40 percent of global greenhouse gas emissions annually. Building operations, which includes lighting, heating, and cooling, are responsible for 27 percent of those emissions. Building materials and the construction process – which is often called embodied carbon – are responsible for another 13 percent every year.

When looking at landscapes, the share of embodied carbon as a percentage of total emissions changes. For landscape architects, approximately 75 percent of project emissions come from materials.

But one major benefit of landscapes is they can store carbon through trees, plants, and soils while also reducing climate impacts and improving ecological and human health. Landscapes are a key part of the broader effort to reduce emissions and drawdown more carbon.

“We know the built environment is more than just buildings. We need to start thinking about whole projects or whole sites instead of whole buildings when we discuss climate solutions,” said ASLA CEO Torey Carter-Conneen, at Sustainability Week US, organized by Economist Impact in Washington, D.C.

In a discussion moderated by Carter-Conneen, government, non-profit, and corporate built environment leaders discussed the collective actions driving down emissions from both buildings and landscapes.

Electrification of the millions of buildings in the U.S. and worldwide is seen as an important next step to reduce operational emissions.

Peter Templeton, CEO of the U.S. Green Building Council, noted that an increasing number of new buildings are now “electricity ready,” meaning they weren’t built with oil or gas-powered furnaces or boilers.

These buildings simply need to be connected to a “green grid” powered by renewable sources, like wind and solar, instead of fossil fuels, like coal, oil, or natural gas. Utilities need to accelerate the shift to renewable energy so the power used in all-electric buildings is clean.

More financing is needed to make the transition to electric buildings and renewable energy happen, said Joe Rozza, chief sustainability officer at Ryan Companies.

To receive private financing from the markets, companies need to show a return on investment with their electrification and energy efficiency improvements. This calculus is complicated by evolving building performance standards in different U.S. state and city jurisdictions.

For companies developing or managing millions of square feet of real estate, one common strategy amid the regulatory flux has been to make incremental improvements to decarbonize each year while also reducing climate and water risks.

But Gina Bocra, chief sustainability officer, New York City Department of Buildings, argued the time of incremental change will soon be over. New government mandates will significantly speed up the decarbonization process.

New York City government is now implementing a “robust new building energy code” — Local Law 97 — a “landmark building performance standard that mandates carbon reductions in our 50,000 largest buildings.” In addition, the city’s recent building electrification law will “restrict fossil fuel combustion in new buildings” starting in 2024. Bocra said these new regulations will help the city become carbon neutral by 2050.

“The city is now obligating building owners to make reductions in their climate impacts each year. 20-30 percent of building energy is wasted every day. Fixing these problems will create jobs, economic opportunities, and improve public health,” she said.

And it is not just NYC taking action: 40 other cities are creating similar regulations.

As cities and developers tackle operational emissions, it’s important not to forget about embodied carbon, Carter-Conneen said.

“We know that concrete and steel are major sources of embodied carbon in buildings. That is also true in landscape architecture projects,” he said.

“We can scale up low-carbon steel and cement and the use of timber and integrated solar panels. We can also reduce the amount of cement required in our buildings,” Bocra said, explaining a few solutions New York City is exploring.

Susan Uthayakumar, chief energy and sustainability officer at Prologis, a logistics company that manages 1.2 billion square feet of real estate worldwide, sees opportunities to reduce embodied carbon through economies of scale.

$40 billion in concrete is procured each year from giant companies like Cemex. Through advocacy and aggregating demand, companies can “accelerate the transition to low-carbon concrete.”

Templeton also urged the audience to think about “whole life carbon” — to look at it holistically as a resource. He noted that environmental product declarations (EPDs) are key to measuring the life cycle of embodied carbon in materials — from extraction to creation and reuse. The idea is to achieve a circular approach, leveraging the carbon in materials again and again.

Architects, landscape architects, developers — and the governments shaping their projects — are also now looking at how to maximize the many co-benefits of decarbonization.

Templeton noted that the Sustainable Sites Initiative (SITES) — which is a result of a partnership between ASLA, the U.S. Botanic Garden, and the Lady Bird Johnson Wildflower Center at the University of Texas at Austin — offered an early framework for decarbonization while also increasing the environmental and human health co-benefits of landscapes.

SITES showed developers the value in “investing in green infrastructure, public rights of way, building sites — they are all part of the solution,” he said.

Rozza also sees the landscape around buildings as critical to realizing co-benefits. “With green infrastructure and focusing on biodiversity and water, we can extend the value of the experience of the property.” There is a return on investment from creating “immersive landscape experiences for tenants.”

Since 2019, New York City has required new buildings and significantly renovated ones to add green roofs or rooftop solar. Green roofs reduce stormwater runoff. But what many don’t realize is that stormwater management has a carbon connection. “It takes a lot of energy to move and treat stormwater in waste water treatment plants.” So less water treated means less energy used and lower emissions.

And Uthayakumar said many of her company’s facilities are extending renewable energy co-benefits. Rooftop solar on their logistics centers is now powering their electric vehicles, which means cleaner air for surrounding communities. And their rooftop solar is also powering neighboring homes. “This just makes sense from a business perspective.”

“When we talk about decarbonization, we also need to talk about equity. As we know, not everyone has access to the benefits that come with green buildings and healthy landscapes that store carbon,” Carter-Conneen said.

To address this, the “Biden-Harris administration has focused on increasing investment in underserved communities through the Infrastructure Investment and Jobs Act, Inflation Reduction Act, and implementation of the Justice 40 initiative.”

“How can we make sure more communities reap the rewards of decarbonization?” he asked.

For Bocra, those federal funds have helped implement NYC’s decarbonization plans in a more equitable way.

“We have 1.1 million buildings in the city. We need to decarbonize 130 buildings every week until 2050. We have affordable housing and building owners in disadvantaged communities. We seek to lift up these building owners through training, direct assistance, and financing.”

And looking at the global scale, Templeton said “we need to bring green buildings to all. Green building councils are active in 180 countries. With significant investment, we can help developing countries leapfrog developed countries, learn new skills, and create new jobs.”

Park(ing) Day is Friday, September 15. The focus of this year’s Park(ing) Day, which is now in its 17th year, is pollinators.

Birds, bats, bees, butterflies, and other insects need our help more than ever. Use your Park(ing) Day space to educate the public. Show them how landscape architects create healthy places for an important pollinator in your community.

You can use your space to:

  • Provide educational materials about a pollinator in your community that is at risk
  • Show native plants the pollinator relies on
  • Create an interactive game or demonstration that teaches how to design habitat

Post images of your Park(ing) Day installation to your social (Facebook, Twitter, Instagram). Use the hashtag #ParkingDay and tag us (@Nationalasla)

Make sure you have permission or signed release forms from anyone you photograph.

ASLA will highlight the best posts from students, firms, and chapters across our social platforms!

Ideas for How to Highlight Pollinators

In 2019, MKSK partnered with the Washington, D.C. Department of Energy and Environment (DOEE) and the US National Arboretum for Park(ing) Day. The team transformed two parking spots in downtown Washington, D.C. into a native “Pollinator Gallery” that educated the public about the importance of pollinators and the role landscape architects play in protecting them.

Landscape architects showed the world from a bee’s perspective. “We show how color perception, habitat requirements, and food source change throughout the seasons and are vital to understanding how to create functional ecosystems in designed landscapes,” MKSK explains.

Their Park(ing) Day installation included a meadow of potted native perennials and grasses, and a field of pinwheels, ranging from violet to yellow. “They were painted to represent patterns of ultra-violet light that bees see on flower petals.” The pinwheels were also “fixed at varying heights to indicate the yearly summer peak of insect biomass and its overall decline in recent decades.”

Two bee box brackets “mimic the nesting tunnels created in the ground by solitary, native bees.” The brackets also became an “unexpected, impromptu photo booth for enthusiastic Park(ing) Day visitors.”

Climate Change Is Driving Canada’s Worst-Ever Wildfire Season

Fire Map, June 8. 2023 / Canadian Natural Resources

Canada’s Minister of Emergency Preparedness said that 9.4 million acres of forests have already burned in Canada, 15 times higher than the 10-year average. And, unfortunately, this is just the start of the summer wildfire season. The Canadian government points to climate change as the culprit.

Wildfires are common in Canada, but “it is unusual for blazes to be burning simultaneously in the east and west,” Reuters reported. There have been more than 2,300 wildfires just this year. Many of the worst fires have occurred in the Eastern province of Quebec, where 11,000 people have been evacuated. Five Canadian provinces, covering a broad swath of the country, have been impacted.

Climate change is causing abnormal weather patterns, increased temperatures, and droughts, leading to drier forests. When combined with growing forest fuels — which include combustible pine needles, twigs, shrubs, and dead trees — wildfire risks significantly increase.

In additional to abnormally dry conditions, extreme heat has been cited as a cause of the early, widespread conflagrations this year. The Washington Post reports that the Canadian provinces of Alberta, Nova Scotia, and Quebec have “experienced record heat.” Areas in Alberta recorded temperatures more than 12.6 F hotter than in a typical May.

Parts of Canada have experienced a “heat dome,” a high-pressure system, which spurred on early fires in its prairie region. Florida-based meteorologist Jeffery Berardelli told The Guardian, “a ‘heat dome’ like this is a very rare occurrence in this part of the world this time of year. Historically and statistically speaking, it is rarer than a 1-in-1,000-year event.” With climate change, heat domes are expected to occur earlier and more often, putting greater pressure on Canadian and other forests.

In the United States, smoke from the wildfires has blanketed the Midwest, Northeast, Mid-Atlantic, and is heading towards the South and Southeast. An interactive map from BlueSky Canada shows the extent and movement of the smoke in near real-time. Air quality in New York City and other Northeastern cities have been the worst on record.

So far this year, Americans on the East Coast have inhaled more wildlife smoke than those on the West Coast, argues Heatmap. Wildfires have significantly increased air pollution in Western states for many years, but now it’s a national issue. In The New York Times, David Wallace-Wells writes: “Across the country, the number of people exposed to what are sometimes called extreme smoke days has grown 27-fold in just a decade, and exposure to even-more-extreme smoke events has grown 11,000-fold.”

Landscape architects have been planning and designing solutions to reduce wildfire risks. These include planning communities with wise land-use approaches that reduce fire risks associated with the wildland-urban interface; designing more fire-resilient public landscapes; and protecting communities, schools, and other critical infrastructure through Firewise or defensible space approaches.

In a post from 2020, Rob Ribe, FASLA, PhD, professor and director of the master’s of landscape architecture program at the University of Oregon, told us: “Fuels reduction is the only known option to increase forests’ resilience. Prescribed portions of young or smaller trees, dead wood, and shrubs could be reduced in hundreds of millions of acres in the American West, and again, later on, in the forests of the eastern states. This is happening at a growing pace, but piecemeal, wherever funding and political support coalesce. It’s not enough to meet the larger challenge.”

With climate change, Canada’s national, provincial, and territorial governments also clearly need more resources to reduce forest fuels, including through controlled burns, and restore forests. The number of out-of-control fires continues to grow.

The Landscapes of the Black Atlantic World (Part II)

The institution of slavery shaped landscapes on both sides of the Atlantic Ocean. And in turn enslaved and free Africans and their descendants created new landscapes in the United States, the Caribbean, and Sub-Saharan Africa. African people had their own intimate relationships with the land, which enabled them to carve out their own agency and culture.

At Dumbarton Oaks in Washington, D.C., a symposium — Environmental Histories of the Black Atlantic World: Landscape Histories of the African Diaspora — organized by N. D. B. Connolly, a professor at Johns Hopkins University, and Oscar de la Torre, a professor at the University of North Carolina at Charlotte, sought to highlight those forgotten relationships between people and their environment.

In the 18th and 19th centuries, slaves brought from Sub-Saharan Africa were central to the production of many U.S. and Caribbean commodities, including cotton, tobacco, rice, rum, and sugar, and the industrialization and financial markets that resulted from them. The success of the Domino Sugar Company and its refinery on the waterfront of Williamsburg, Brooklyn, was a direct result of enslaved labor. As such, “Brooklyn is a part of the Black Atlantic,” said Emily Holloway, a PhD student at Clark University. “Slavery in the south and Caribbean underwrote industrialization in the North.”

Holloway uses multiple academic disciplines to disentangle the “messy reality of racial capitalism,” which runs from Africa to Haiti, Cuba to the Northeast. This economic system relied on slaves and the accumulation of capital, which took the form of buildings and infrastructure.

The success of the Domino Sugar Company can also be understood as a result of a slave rebellion, which drove major changes in the sugar cane economy of the Caribbean. “The beginnings of the Domino Sugar Company leads back to the Haitian revolution,” Holloway said.

Self-liberated Haitians rose up and defeated the French colonial army, which caused sugar plantation owners on the island to flee to eastern Cuba. There, they clear-cut the land and reinstalled their slave-based sugar cane economy. This sugar was then sent to New York City for processing as the granular table sugar consumers bought in stores.

William Havemeyer, the founder of a company that later grew into Domino Sugar Company and later Domino Foods, Inc., formed a sugar refinery in lower Manhattan in 1807. Fifty years later, his firm moved to Williamsburg, where they built a larger refinery.

After that burnt down, the company built a colossal building in 1883 that could produce a million pounds of sugar a day. The company took up four city blocks and created a “densely populated industrial ecosystem.” Today, the building is being redeveloped as an office building, and the Domino waterfront has become “gentrified” and transformed into a park.

This industrialization process was mirrored in the sugar cane plantation landscapes of Cuba. Small farms multiplied and grew in size. Enslaved and then free laborers were still needed to harvest the cane but the processing at the farms became increasingly mechanized. “This history has been largely erased in the archives,” Holloway said, and a “more creative approach to research is needed.”

Holloway said the artist Kara Walker spoke of these relationships with her monumental, 75-foot-tall sculpture, A Subtlety or the Marvelous Sugar Baby, created in 2014 for then derelict Domino sugar factory space. “This was the Black Atlantic answering back in defiance.”

Justin Dunnavant, a professor at the University of California, Los Angeles, approaches the history of the Caribbean through multiple academic lenses as well.

He said there are researchers exploring the ideas of Black ecology, which examines the unique ways Black people interact with nature and how they are also erased from the environment. And there are also researchers focused on historical ecology, looking at how relationships between societies and environments have changed over time.

His goal is to synthesize these approaches into the new study of Black historical ecology, which can explore how ecological relations changed because of the slave trade. This will involve weaving together multiple narratives to examine the plantation system’s impact on both terrestrial and marine ecosystems. His hope is it can result in “a call to action to redress.”

Dunnavant has focused on the island of St. Croix, which was part of the Danish West Indies and is now part of the U.S. Virgin Islands. As part of an archeological research collective, he and his team are investigating the ecological impacts of slavery and plantations, including the deforestation that occurred to clear lands for sugar cane; the soils that were degraded by agriculture and development; and the coral mined for buildings. His work is also a part of the Estate Little Princess Maritime and Terrestrial Archaeology Field School, which trains Crucian high-school students in archaeology while investigating the remnants of Danish slavery.

At the same time, he is also uncovering the little known legacy of the maroons that claimed isolated areas of the island. Maroons were Black slaves who freed themselves by escaping, and some were their descendants. They formed self-sufficient communities throughout the Caribbean and southern United States. They often mixed with Indigenous peoples, forming new creole communities. In St. Croix, they led a slave rebellion that ended slavery in 1848.

The part of the island where the maroons found sanctuary was “unmapped” in Danish historical records, but it was actually a “rich area of Black freedom.” Using Lidar data and other archeological tools, Dunnavant’s team is uncovering the remnants of what he calls a “Black geography.” He is interested in how the maroons terraced the land for agriculture and created fortifications and leveraged the dense landscape to protect themselves. “Uncovering their stories is a form of redress.”

Matthew Francis Rarey, a professor at Oberlin College, then took the audience to Brazil to focus on the Portuguese colonial empire and its deadly campaign against maroons.

Approximately 80 fugitive slaves had made a home at Buraco do Tatu, on the coast of Bahia in Northeast Brazil. Their quilombo, or fugitive community, was destroyed by colonial forces. And that destruction was documented in a unique map that accompanied a letter to the viceroy.

Map of Quilombo at Buraco do Tatu / Capoeira Online

The map was meant to provide evidence of the colonial power’s success in suppressing maroons, but it has become an “icon of scholarship,” as it is one of the few comprehensive aerial perspectives on how maroons organized themselves.

The map depicts a community nestled in sand dunes and blended into surrounding trees and shrubs. At its outer perimeter are fields of surrounding wood spikes. There are spiked trap holes. And there’s also a single path to the sea. The inner sanctum, the community itself, is organized on a grid, with homes arranged by streets. And there are food gardens and a trellis for growing passion fruit. “It shows a rebellion landscape,” Rarey said.

The maroons would use the path to reach roads where they would rob wayfarers. “They were fighting against inequality and capitalism.” The maroons would also target enslaved Black people going to market in an attempt to strike a blow at the plantation economy. “Their goal was to dismantle plantations from the inside” by “weaponizing blackness” and making plantation owners “look foolish,” Rarey said. They also participated in informal exchanges to build their supply of guns and gunpowder.

The map includes a legend that explains how the maroon community were killed in the onslaught by Portuguese colonial forces. One maroon woman was labeled a sorceress and “defamed after her death.” Many others killed themselves instead of risking re-enslavement. In the map, the corpses become “part of the subjugated landscape.”

The Portuguese process of mapping the community is an attempt to reinstate colonial order on a free Black landscape. Rarey said you can sense the “anxiety of the cartographer” as they had “no reference point.”

The institution of slavery shaped landscapes on both sides of the Atlantic Ocean. And in turn enslaved and free Africans and their descendants created new landscapes in the United States, the Caribbean, and Sub-Saharan Africa. African people had their own intimate relationships with the land, which enabled them to carve out their own agency and culture.

At Dumbarton Oaks in Washington, D.C., a symposium — Environmental Histories of the Black Atlantic World: Landscape Histories of the African Diaspora — organized by N. D. B. Connolly, a professor at Johns Hopkins University, and Oscar de la Torre, a professor at the University of North Carolina at Charlotte, sought to highlight those forgotten relationships between people and their environment.

Thaisa Way, FASLA, director of the garden and landscape studies department at Dumbarton Oaks, said the symposium was the fourth in a series meant to “curate a people’s history of landscape.”

African slaves in the United States’ Southern states and the Caribbean were forced to work in their owners’ plantations. They were seen as cogs in an industrial farming system driven by a trans-Atlantic capitalist market economy. But many owners also set aside land slaves could use to grow, trade, and sell food. “This was advantageous for the slave owner,” said C.C. McKee, a professor at Bryn Mawr College and the University of Copenhagen, as it meant having to spend less on feeding them.

McKee is intrigued by a painting by the artist simply known as Le Masurier, created in the French colony of Martinique in the 1770s (see image above). It clearly shows slave children eating sugar cane, the result of the plantation monoculture, but also the “Afro-Caribbean ecologies,” the many African and native trees and plants slaves planted at the edges of plantations, including cashew and tamarind, pea, and starfruit.

According to historical accounts of plantation life during that time, slaves also planted potatoes, yams, cabbages, herbs, and melons. They blended native Caribbean and African plants, taking a “creolized approach to food production.”

The edges of plantations were places where African social structures could be asserted. In these remnant spaces, slaves could decide how to parcel and cultivate the land. And while slave ownership of these areas was impossible, in some communities, hereditary claims were made on parcels, and kinship structures could play a role. In some communities, they functioned as a slave commons. They were “sites of resistance” to the slave owner’s world.

What isn’t seen in the painting McKee highlights is a depiction of the important role indigenous Caribbean peoples played in cultivating trees and plants, and on many islands, their role in teaching Africans how to harvest and prepare food from them. “The indigenous people have been ghosted because they were completely expelled by the 18th century. They were exterminated and exported; it was genocide.”

Slave children also had a complex relationship with the landscapes of the American South, explained Mikayla Janee Harden, a PhD student at the University of Delaware. They were put at greater risk by a dangerous landscape but also “knowingly imprinted on that landscape,” she said.

Children were left on their own or in the care of an elder while their parents worked the fields. Depending on their age, many were also tasked with clean-up and other responsibilities.

On plantations, slaves lived near untamed landscapes. Children who worked and played in these places without shoes were at great risk from snake bites. The few references to slave children in historical records relate to the medical knowledge gleaned from these bites. Children’s lack of “experience, wisdom, and judgement increased their risk of environmental harm.”

But children could also benefit from their “tacit knowledge” of the landscape. While still enslaved, some apprenticed at a young age to learn important trades. Harden highlights the example of Edmond Albius. Enslaved as a child on the French island colony of Reunion, he discovered a highly efficient way to cultivate vanilla that is still used today.

Landscape was a source of “pain and pleasure” for enslaved children. Untended by their working parents, they could be bitten by snakes or have accidents but could also learn, play, and imagine. Harden is next exploring the material culture — the corn-husk dolls and games enslaved children created — and how these objects transmitted African folklore and culture to the next generation.

The conversation then shifted to the other side of the Atlantic. The landscapes of the Falémé Valley in western Sub-Saharan Africa are a source of deep interest for Jacques Aymeric-Nsangou, a professor at the University of Manitoba in Canada. The valley provides insights into how African people avoided the process of enslavement and commodification.

Aymeric-Nsangou decided to research the hinterlands because most Africans captured and enslaved came from the interior, not the coasts. “Many had never seen the ocean before” when they were loaded into slave ships at coastal ports.

The Falémé River spans approximately 250 miles and flows south to north — from northern Guinea, through Mali and Senegal. It flows through mountains, forests, and deserts, and experiences dramatic seasonal changes. It is a tributary of the Senegal River, which flows east to west, so it could be used by slavers to carry captured people to ports on the western coast.

The landscape of the valley included both independent kingdoms and villages of the varied Madinka (otherwise known as the Manlinke or Mandingo) people, who are of similar ethnic origins. They were targeted by the Muslim Fulani (or Fulu) kingdom for capture as part of jihad (holy war). Enslavement had a long history in this part of the world. For centuries, captives were taken as a product of war. People could also be enslaved if, after a trial, they were deemed criminal or for other reasons.

Aymeric-Nsangou explored the few remnants of Tatas, the fortified defensive homes and landscapes of the region, with a team of archeologists. “The Tatas didn’t appear before the 18th century; they increased because of the slave trade,” Aymeric-Nsangou said.

There are no remaining, intact Tatas in the region, because the French colonial government largely destroyed them. But historic photographs show they were made with raw mud cement and stone.

The interiors of the Tatas were labyrinthine and had multiple layers of walls. Noble families occupied the innermost Tata, which also had the strongest walls. Outside, wood palisades, which are still seen in many communities today, provided an extra layer of security against slavers. And these communities also sometimes “weaponized African bees.” These insects are famously aggressive. And “there are stories that villagers could command them to attack.”

While the Tatas could offer defense, they could also be a trap. Another strategy villagers in the region took was to keep their community small so they could quickly relocate.
