    Ancient Amazonians intentionally created fertile “dark earth”

    The Amazon river basin is known for its immense and lush tropical forests, so one might assume that the Amazon’s land is equally rich. In fact, the soils underlying the forested vegetation, particularly in the hilly uplands, are surprisingly infertile. Much of the Amazon’s soil is acidic and low in nutrients, making it notoriously difficult to farm.

    But over the years, archaeologists have dug up mysteriously black and fertile patches of ancient soils in hundreds of sites across the Amazon. This “dark earth” has been found in and around human settlements dating back hundreds to thousands of years. And it has been a matter of some debate as to whether the super-rich soil was purposefully created or a coincidental byproduct of these ancient cultures.

    Now, a study led by researchers at MIT, the University of Florida, and in Brazil aims to settle the debate over dark earth’s origins. The team has pieced together results from soil analyses, ethnographic observations, and interviews with modern Indigenous communities, to show that dark earth was intentionally produced by ancient Amazonians as a way to improve the soil and sustain large and complex societies.

    “If you want to have large settlements, you need a nutritional base. But the soil in the Amazon is extensively leached of nutrients, and naturally poor for growing most crops,” says Taylor Perron, the Cecil and Ida Green Professor of Earth, Atmospheric and Planetary Sciences at MIT. “We argue here that people played a role in creating dark earth, and intentionally modified the ancient environment to make it a better place for human populations.”

    And as it turns out, dark earth contains huge amounts of stored carbon. As generations worked the soil, for instance by enriching it with scraps of food, charcoal, and waste, the earth accumulated the carbon-rich detritus and kept it locked up for hundreds to thousands of years. By purposely producing dark earth, then, early Amazonians may have also unintentionally created a powerful, carbon-sequestering soil.

    “The ancient Amazonians put a lot of carbon in the soil, and a lot of that is still there today,” says co-author Samuel Goldberg, who performed the data analysis as a graduate student at MIT and is now an assistant professor at the University of Miami. “That’s exactly what we want for climate change mitigation efforts. Maybe we could adapt some of their indigenous strategies on a larger scale, to lock up carbon in soil, in ways that we now know would stay there for a long time.”

    The team’s study appears today in Science Advances. Other authors include former MIT postdoc and lead author Morgan Schmidt, anthropologist Michael Heckenberger of the University of Florida, and collaborators from multiple institutions across Brazil.

    Modern intent

    In their current study, the team synthesized observations and data that Schmidt, Heckenberger, and others had previously gathered, while working with Indigenous communities in the Amazon since the early 2000s,  with new data collected in 2018-19. The scientists focused their fieldwork in the Kuikuro Indigenous Territory in the Upper Xingu River basin in the southeastern Amazon. This region is home to modern Kuikuro villages as well as archaeological sites where the ancestors of the Kuikuro are thought to have lived. Over multiple visits to the region, Schmidt, then a graduate student at the University of Florida, was struck by the darker soil around some archaeological sites.

    “When I saw this dark earth and how fertile it was, and started digging into what was known about it, I found it was a mysterious thing — no one really knew where it came from,” he says.

    Schmidt and his colleagues began making observations of the modern Kuikuro’s practices of managing the soil. These practices include generating “middens” — piles of waste and food scraps, similar to compost heaps, that are maintained in certain locations around the center of a village. After some time, these waste piles decompose and mix with the soil to form a dark and fertile earth, that residents then use to plant crops. The researchers also observed that Kuikuro farmers spread organic waste and ash on farther fields, which also generates dark earth, where they can then grow more crops.

    “We saw activities they did to modify the soil and increase the elements, like spreading ash on the ground, or spreading charcoal around the base of the tree, which were obviously intentional actions,” Schmidt says.

    In addition to these observations, they also conducted interviews with villagers to document the Kuikuro’s beliefs and practices relating to dark earth. In some of these interviews, villagers referred to dark earth as “eegepe,” and described their daily practices in creating and cultivating the rich soil to improve its agricultural potential.

    Based on these observations and interviews with the Kuikuro, it was clear that Indigenous communities today intentionally produce dark earth, through their practices to improve the soil. But could the dark earth found in nearby archaeological sites have been made through similar intentional practices?

    A bridge in soil

    In search of a connection, Schmidt joined Perron’s group as a postdoc at MIT. Together, he, Perron, and Goldberg carried out a meticulous analysis of soils in both archaeological and modern sites in the Upper Xingu region. They discovered similarities in dark earth’s spatial structure: Deposits of dark earth were found in a radial pattern, concentrating mostly in the center of both modern and ancient settlements, and stretching, like spokes of a wheel, out to the edges. Modern and ancient dark earth was also similar in composition, and was enriched in the same elements, such as carbon, phosphorus, and other nutrients.

    “These are all the elements that are in humans, animals, and plants, and they’re the ones that reduce the aluminum toxicity in soil, which is a notorious problem in the Amazon,” Schmidt says. “All these elements make the soil better for plant growth.”

    “The key bridge between the modern and ancient times is the soil,” Goldberg adds. “Because we see this correspondence between the two time periods, we can infer that these practices that we can observe and ask people about today, were also happening in the past.”

    In other words, the team was able to show for the first time that ancient Amazonians intentionally worked the soil, likely through practices similar to today’s, in order to grow enough crops to sustain large communities.

    Going a step further, the team calculated the amount of carbon in ancient dark earth. They combined their measurements of soil samples, with maps of where dark earth has been found through several ancient settlements. Their estimates revealed that each ancient village contains several thousand tons of carbon that has been sequestered in the soil for hundreds of years as a result of Indigenous, human activities.

    As the team concludes in their paper, “modern sustainable agriculture and climate change mitigation efforts, inspired by the persistent fertility of ancient dark earth, can draw on traditional methods practiced to this day by Indigenous Amazonians.”

    This research at MIT was supported, in part, by the Abdul Latif Jameel Water and Food Systems Lab and the Department of the Air Force Artificial Intelligence Accelerator. Field research was supported by grants to the University of Florida from the National Science Foundation, the Wenner-Gren Foundation and the William Talbott Hillman Foundation, and was sponsored in Brazil by the Museu Goeldi and Museu Nacional.

    Q&A: Steven Gonzalez on Indigenous futurist science fiction

    Steven Gonzalez is a PhD candidate in the MIT Doctoral Program in History, Anthropology, Science, Technology, and Society (HASTS), where he researches the environmental impacts of cloud computing and data centers in the United States, Iceland, and Puerto Rico. He is also an author. Writing under the name E.G. Condé, he recently published his first book, “Sordidez.” It’s described as an “Indigenous futurist science fiction novella set in Puerto Rico and the Yucatán.” Set in the near future, it follows the survivors of civil war and climate disaster led by protagonist Vero Diaz, as they reclaim their Indigenous heritage and heal their lands.

    In this Q&A, Gonzalez describes the book’s themes, its inspirations, and its connection to research, people, and classes at MIT.

    Q: Where did the inspiration for this story come from?

    A: I actually began my time at MIT in September of 2017 when Hurricane María struck. It was a really difficult time for me at the Institute, starting a PhD program. And it’s MIT, so there’s a lot of pressure. I was still kind of navigating the new institutional space and trying to understand my place in it. But I had a lot of people at the Institute who were extremely supportive during that time. I had family members in Puerto Rico who were stranded as a result of the hurricane, who I didn’t hear from for a very long time — who I feared dead. It was a very, very chaotic, confusing, and emotionally turbulent time for me, and also incredibly difficult to be trying to be present in a PhD program for the first semester. Karen Gardner, our administrator, was really incredibly supportive in that. Also the folks at the MIT Association of Puerto Ricans, who hosted fundraisers and linked students with counseling resources. But that trauma of the hurricane and the images that I saw of the aftermath of the hurricane, specifically in the town where my grandmother’s house was where I spent time living as a child during the summers, and to me, it was the greenest place that I have ever known. It looked like somebody had torched the entire landscape. It was traumatizing to see that image. But that kind of seeded the idea of, is there a way to burn without fire? There’s climate change, but there’s also climate terror. And so that was sort of one of the premises of the book explores, geoengineering, but also the flip side of geoengineering and terraforming is, of course, climate terror. And in a way, we could frame what’s been happening with the fossil fuel industry as a form of climate terror, as well. So for me, this all began right when I started at MIT, these dual tracks of thought.

    Q: What do you see as the core themes of your novella?

    A: One major theme is rebuilding. As I said, this story was very influenced by the trauma of Hurricane María and the incredibly inspiring accounts from family members, from people in Puerto Rico that I know, of regular people stepping up when the government — both federal and local — essentially abandoned them. There were so many failures of governance. But people stepped up and did what they could to help each other, to help neighbors. Neighbors cleared trees from roads. They banded together to do this. They pooled resources, to run generators so that everyone in the same street could have food that day. They would share medical supplies like insulin and things that were scarce. This was incredibly inspiring for me. And a huge theme of the book is rebuilding in the aftermath of a fictive hurricane, which I call Teddy, named after President Theodore Roosevelt, where Puerto Rico’s journey began as a U.S. commonwealth or a colony.

    Healing is also a huge theme. Healing in the sense of this story was also somewhat critical of Puerto Rican culture. And it’s refracted through my own experience as a queer person navigating the space of Puerto Rico as a very kind of religious and traditional place and a very complex place at that. The main character, Vero, is a trans man. This is a person who’s transitioned and has felt a lot of alienation and as a result of his gender transition, a lot of people don’t accept him and don’t accept his identity or who he is even though he’s incredibly helpful in this rebuilding effort to the point where he’s, in some ways, a leader, if not the leader. And it becomes, in a way, about healing from the trauma of rejection too. And of course, Vero, but other characters who have gone through various traumas that I think are very much shared across Latin America, the Latin American experiences of assimilation, for instance. Latin America is a very complex place. We have Spanish as our language, that is our kind of lingua franca. But there are many Indigenous languages that people speak that have been not valued or people who speak them or use them are actively punished. And there’s this deep trauma of losing language. And in the case of Puerto Rico, the Indigenous language of the Taínos has been destroyed by colonialism. The story is about rebuilding that language and healing and “becoming.” In some ways, it’s about re-indigenization. And then the last part, as I said, healing, reconstruction, but also transformation and metamorphosis. And becoming Taíno. Again, what does that mean? What does it mean to be an Indigenous Caribbean in the future? And so that’s one of the central themes of the story.

    Q: How does the novella intersect with the work you’re doing as a PhD candidate in HASTS?

    A: My research on cloud computing is very much about climate change. It’s pitched within the context of climate change and understanding how our digital ecosystem contributes to not only global warming, but things like desertification. As a social scientist, that’s what I study. My studies of infrastructure are also directly referenced in the book in a lot of ways. For instance, the now collapsed Arecibo Ionosphere Observatory, where some of my pandemic fieldwork occurred, is a setting in the book. And also, I am an anthropologist. I am Puerto Rican. I draw both from my personal experience and my anthropological lens to make a story that I think is very multicultural and multilingual. It’s set in Puerto Rico, but the other half is set in the Yucatán Peninsula in what we’ll call the former Maya world. And there’s a lot of intersections between the two settings. And that goes back to the deeper Indigenous history. Some people are calling this Indigenous futurism because it references the Taínos, who are the Indigenous people of Puerto Rico, but also the Mayas, and many different Maya groups that are throughout the Yucatán Peninsula, but also present-day Guatemala and Honduras. And the story is about exchange between these two worlds. As someone trained as an anthropologist, it’s a really difficult task to kind of pull that off. And I think that my training has really, really helped me achieve that.

    Q: Are there any examples of ways being among the MIT community while writing this book influenced and, in some ways, made this project possible?

    A: I relied on many of my colleagues for support. There’s some sign language in the book. In Puerto Rico, there’s a big tradition of sign language. There’s a version of American sign language called LSPR that’s only found in Puerto Rico. And that’s something I’ve been aware of ever since I was a kid. But I’m not fluent in sign language or deaf communities and their culture. I got a lot of help from Timothy Loh, who’s in the HASTS program, who was extremely helpful to steer me towards sensitivity readers in the deaf community in his networks. My advisor, Stefan Helmreich, is very much a science fiction person in a lot of ways. His research is on the ocean waves, the history and anthropology of biology. He’s done ethnography in deep-sea submersibles. He’s always kind of thinking in a science fictional lens. And he allowed me, for one of my qualifying exam lists, to mesh science fiction with social theory. And that was also a way that I felt very supported by the Institute. In my coursework, I also took a few science fiction courses in other departments. I worked with Shariann Lewitt, who actually read the first version of the story. I workshopped it in her 21W.759 (Writing Science Fiction) class, and got some really amazing feedback that led to what is now a publication and a dream fulfilled in so many ways. She took me under her wing and really believed in this book. More

    Powering the future in Mongolia

    Nestled within the Tuul River valley and embraced by the southern Khentii Mountain Range, Ulaanbaatar (UB), Mongolia’s largest city, presents itself as an arena where nature’s forces wage an unrelenting battle against human resilience. The capital city is an icy crucible, with bone-chilling winters that plummet temperatures to an astonishing -40 degrees Fahrenheit (-40 degrees Celsius). Mongolia, often hailed with the celestial moniker of “The Land of the Eternal Blue Sky,” paradoxically succumbs to a veil of pollution and energy struggles during the winter months, obscuring the true shade of the cherished vista.

    To understand the root of these issues, MIT students from classes 22.S094 (Climate and Sustainability Systems: Decarbonizing Ulaanbaatar at Scale) and 21A.S01 (Anthro-Engineering: Decarbonization at the Million-Person Scale) visited Mongolia to conduct on-site surveys, diving into the diverse tapestry of local life as they gleaned insight from various stakeholder groups. Setting foot on Mongolian soil on a crisp day in January, they wasted no time in shaking off the weariness of their arduous 17-hour flight, promptly embarking on a waiting bus. As they traversed the vast expanse of the countryside, their eyes were captivated by snow-laden terrain.

    That is, until a disconcerting sight unfolded — thick smog, akin to ethereal pillars, permeated the cityscape ahead. These imposing plumes emanated from the colossal smokestacks of Ulaanbaatar’s coal-fired power plants, steadfastly churning electricity and heat to fuel Mongolia’s central and district energy systems. Over 93 percent of the nation’s energy comes from coal-fired power plants, where the most considerable load is caused by household consumption. Nevertheless, with nearly half of Ulaanbaatar’s population disconnected from the central heating networks, one of Mongolia’s most significant sources of pollution comes from coal-burning stoves in the residential settlements known as the ger districts. Over the past three decades, since the democratic revolution in 1990, Mongolians have grappled with escalating concerns surrounding energy provision, accessibility, and sustainability.

    Engineers who think like anthropologists

    “We find ourselves compelled to venture on-site, engaging in direct conversations with the locals, and immersing ourselves in the fabric of daily life to uncover what we don’t know,” emphasized Michael Short, professor in MIT’s Department of Nuclear Science and Engineering and faculty lead of MIT’s NEET Climate and Sustainability Systems thread, shortly before heading to Mongolia.

    The Ulaanbaatar Project sprang from a multiyear collaboration between MIT and the National University of Mongolia (NUM). Shedding light on the matter, Professor Munkhbat Byambajav of the Department of Chemical and Biological Engineering at NUM underscored the paramount importance of mitigating environmental pollution at an economic scale to alleviate the heavy burden borne by the people.

    Class 22.S094 is offered through MIT’s New Engineering Education Transformation (NEET) program, which allows students with multidisciplinary interests to collaborate across departments within four different subject areas, or threads. In this capstone project, students consider ways to decarbonize a city like Ulaanbaatar, transitioning from burning coal briquettes to a more sustainable, energy-efficient solution, given several parameters and constraints set by the local context.

    One of the ideas students have recently explored is a thermal battery made with molten salt that can store enough energy to heat a ger for up to 12 hours with added insulation for cooling curve regulation. The Mongolian ger, meaning home, is a dome-like portable dwelling covered in felt and canvas, held together by ropes traditionally crafted of animal hair or wool. Over several semesters, students have been testing a version of their proposed idea on campus, working with a prototype that weighs around 35 pounds.

    Nathan Melenbrink, the lead instructor of NEET’s Climate and Sustainability Systems (CSS) thread, believes that the complexity of the Ulaanbaatar capstone project allows students to reject the one-way solution approach and instead consider challenges with a nonprescriptive mindset. The uniqueness of the CSS thread is that students are asked to build on the previous findings from the past cohort and iterate on their designs each year. This workflow has allowed the project to mature and advance in ways that may not be feasible within a semester schedule. When asked how the recent trip impacted the ongoing research back on campus, Melenbrink states, “In light of the recent trip to Mongolia, students are beginning to see the impact of cultural immersion and social awareness leveraging the technical scope and rigor of their work.”

    Course 21A.S01, taught by Professor Manduhai Buyandelger of the MIT Anthropology Section, proved instrumental in deepening students’ understanding of the intricate dynamics at play. She asks, “The prototype works in the lab, but does it work in real life once you factor in the challenges in the larger structures of delivery, production, and implementation in Mongolia?”

    This recognition of the social dimensions of engineering permeated the early stages of the UB project, engaging all participants, including students from MIT and NUM, professionals residing in Mongolia, and local nongovernmental organizations, fostering what Buyandelger aptly describes as “a collaboration on multiple scales: trans-disciplinary and transcontinental.” Lauren Bonilla, co-lecturer for the anthropology course, was crucial in devising the first onsite trip to Mongolia. Drawing upon her extensive ethnographic research in Mongolia that spans decades, Bonilla remarks, “To me, engineering is a highly social discipline.” She further stresses how anthro-engineering elevates the social dimensions of engineering by critically questioning the framing of problems and solutions, stating, “It draws on anthropological insights and methods, like ethnography, to bring a human face to the users of a technology and adds complexity and nuance to the social constraints that limit designs.”

    Making of khorkhog

    Amidst the frigid atmosphere, a traditional Mongolian ger stands in front of the Nuclear Science Laboratory at the National University of Mongolia, emitting warm steam from its roof. The faculty and students of NUM organize a welcoming event inside the ger, inviting everyone to partake in a khorkhog cookout. Earlier that week, a remark from the Mongolian energy representative stood out during one of the presentations: “We need powerful heat. Solar is not enough, and electricity is not enough. Mongolians need fire,” he had emphasized.

    Indeed, the culinary delight known as khorkhog demands the relentless embrace of scorching flames. The process involves a large metal jug, stones, fire, and lamb. With skillful precision, the volunteer chef places the fire-heated stones and large pieces of lamb into the cooking container, triggering a cascade of steam that fills the ger, accompanied by the sounds of sizzling and hissing. Everyone waits patiently as the cook carefully inspects the dish, keenly listening for signs of readiness. And when the time comes, a feast is shared among all, complemented by steam-cooked potatoes, freshly sliced onions, and vegetables. In this moment, the presence of fire symbolizes a profound connection with the heart of Mongolian culture, evoking a deep resonance among the gathered crowd as they partake in this cherished staple meal.

    The distance between two points

    Familiar faces form a grid on the computer screen as the standing meeting between the students in Massachusetts and Ulaanbaatar begins. Sharing the morning (evening in Mongolia) for updates has been a critical effort by both sides to stay engaged and make decisions together. NEET CSS students in Cambridge proceeded to share their latest findings.

    Lucy Nester, a nuclear science and engineering major, has been diligently working on developing a high-efficiency electrical heating solution for individual consumers. Her primary focus is leveraging the discounted electricity rates available in the ger districts and utilize existing infrastructure. Recognizing the importance of maximum flexibility in heating the brick, Nester emphasizes the “no one-size-fits-all” solution. She shares the results of her test trials, which involve both inductive and resistive heating methods, outlining the advantages and disadvantages of each approach. Despite her limited experience in electrical engineering and circuit building, Nester has impressively overcome the steep learning curve. She enthusiastically describes her UB trip as “one of the most remarkable experiences I’ve had during my time at MIT.”

    Darshdeep Grewal, a dedicated materials science and engineering major with a strong passion for data science and computation, has been diligently conducting research on convection heating using COMSOL Multiphysics. In his investigation, Grewal explores the correlation between air temperature and heating, investigates the impact of convecting air arrangement on the heating process, and examines the conditions that may contribute to overheating. Leveraging his expertise in computational workflows, Grewal presents an impressive collection of heatmap simulations derived from the extensive data accumulated by his team throughout the project. Recognizing the immense value of these simulations in modeling complex scenarios, he highlights the importance of running experiments concurrently with simulations to ensure accurate calibration of results, stating, “It’s important to stay rooted in reality.”

    Arina Khotimsky, another materials science and engineering major, has actively engaged in NEET’s Climate and Sustainability Systems thread since her sophomore year. Balancing the demands of her final semester at MIT and the upcoming review of 22.S094, Khotimsky reveals how she has seamlessly integrated her project involvement into her energy studies minor. Reflecting on her journey, she remarks, “Working on the Ulaanbaatar project has taught me the significance of taking local context into account while suggesting solutions as an engineer.” Khotimsky has been tirelessly iterating and refining the insulation box prototype, which holds the thermal battery and controls the rate at which the battery releases heat. In addition, the on-site observations have unveiled another design challenge — ensuring the insulation box functions as a secure and dependable means of transportation. 

    To “engineer” means to contrive through one’s deliberate use of skills. What confronted the UB Project team on site was not the limitations of skill or technology, but the real-world constraints often amiss in the early equation: the people and their everyday lives. With over 6,195 miles of distance between the two groups, it takes more than just dedication to make a collaboration blossom. That may be the desire for a positive impact. Moreover, it may be the goal of cultivating a healthier relationship with energy that spans a million-person scale. No matter where you are, there is no one solution to the complex story of energy. This progressive realization brings the two teams together every two weeks in virtual space, bridging the distance between the two points.  More

    Living Climate Futures initiative showcases holistic approach to the climate crisis

    The sun shone bright and warm on the Dertouzos Amphitheater at the Stata Center this past Earth Day as a panel of Indigenous leaders from across the country talked about their experiences with climate activism and shared their natural world philosophies — a worldview that sees humanity as one with the rest of the Earth.

    “I was taught the natural world philosophies by those raised by precolonial individuals,” said Jay Julius W’tot Lhem of the Lummi tribe of the Pacific Northwest and founder and president of Se’Si’Le, an organization dedicated to reintroducing Indigenous spiritual law into the mainstream conversation about climate. Since his great-grandmother was born in 1888, he grew up “one hug away from pre-contact,” as he put it.

    Natural world philosophiesNatural world philosophies sit at the center of the Indigenous activism taking place all over the country, and they were a highlight of the Indigenous Earth Day panel — one part of a two-day symposium called Living Climate Futures. The events were hosted by the Anthropology and History sections and the Program on Science, Technology, and Society in MIT’s School of Humanities, Arts, and Social Sciences (SHASS), in collaboration with the MIT Office of Sustainability and Project Indigenous MIT.

    “The Living Climate Futures initiative began from the recognition that the people who are living most closely with climate and environmental struggles and injustices are especially equipped to lead the way toward other ways of living in the world,” says Briana Meier, ACLS Emerging Voices Postdoctoral Fellow in Anthropology and an organizer of the event. “While much climate action is based in technology-driven policy, we recognize that solutions to climate change are often embedded within and produced in response to existing social systems of injustice and inequity.”

    On-the-ground experts from around the country spoke in a series of panels and discussions over the two days, sharing their stories and inspiring attendees to think differently about how to address the environmental crisis.

    Gathering experts

    The hope, according to faculty organizers, was that an event centered on such voices could create connections among activists and open the eyes of many to the human element of climate solutions.

    Over the years, many such solutions have overlooked the needs of the communities they are designed to help. Streams in the Pacific Northwest, for example, have been dammed to generate hydroelectric power — promoted as a green alternative to fossil fuel. But these same locations have long been sacred spots for Indigenous swimming rituals, said Ryan Emanuel (Lumbee), associate professor of hydrology at Duke University and a panelist in the Indigenous Earth Day event. Mitigating the environmental damage does not make up for the loss of sacred connection, he emphasized.

    To dig into such nuances, the organizers invited an intergenerational group of panelists to share successes with attendees.

    Transforming urban spaces

    In one panel, for example, urban farmers from Mansfield, Ohio, and Chelsea, Massachusetts, discussed the benefits of growing vegetables in cities.

    “Transforming urban spaces into farms provides not just healthy food, but a visible symbol of hope, a way for people to connect and grow food that reflects their cultures and homes, an economic development opportunity, and even a safe space for teens to hang out,” said Susy Jones, senior sustainability project manager in the MIT Office of Sustainability and an event organizer. “We also heard about the challenges — like the cost of real estate in Massachusetts.”

    Another panel highlighted the determined efforts of a group of students from George Washington High School in Southeast Chicago to derail a project to build a scrap metal recycling plant across the street from their school. “We’re at school eight hours a day,” said Gregory Miller, a junior at the school. “We refuse to live next door to a metals scrapyard.”

    The proposed plant was intended to replace something similar that had been shut down in a predominantly white neighborhood due to its many environmental violations. Southeast Chicago is more culturally diverse and has long suffered from industrial pollution and economic hardship, but the students fought the effort to further pollute their home — and won.

    “It was hard, the campaign,” said Destiny Vasquez. “But it was beautiful because the community came together. There is unity in our struggle.”

    Recovering a common heritage 

    Unity was also at the forefront of the discussion for the Indigenous Earth Day panel in the Stata Amphitheater. This portion of the Living Climate Futures event began with a greeting in the Navajo language from Alvin Harvey, PhD candidate in aeronautics and astronautics (Aero/Astro) and representative of the MIT American Indian Science and Engineering Society and the MIT Native American Student Association. The greeting identified all who came to the event as relatives.

    “Look at the relatives next to you, especially those trees,” he said, gesturing to the budding branches around the amphitheater. “They give you shelter, love … few other beings are willing to do that.”

    According to Julius, such reverence for nature is part of the Indigenous way of life, common across tribal backgrounds — and something all of humanity once had in common. “Somewhere along the line we all had Indigenous philosophies,” he said. “We all need an invitation back to that to understand we’re all part of the whole.”

    Understanding the oneness of all living things on earth helps people of Indigenous nations feel the distress of the earth when it is under attack, speakers said. Donna Chavis, senior climate campaigner for Friends of the Earth and an elder of the Lumbee tribe, discussed the trauma of having forests near her home in the southeastern United States clear-cut to provide wood chips to Europe.

    “They are devastating the lungs of the earth in North Carolina at a rate faster than in the Amazon,” she said. “You can almost hear the pain of the forest.”

    Small pictures of everyday life

    “People are experiencing a climate crisis that is global in really different ways in different places,” says Heather Paxson, head of MIT Anthropology and an event organizer. “What came out of these two days is a real, palpable sense of the power of listening to individual experience. Not because it gives us the big picture, but because it gives us the small picture.”

    Trinity Colón, one of the leaders of the group from George Washington High School, impressed on attendees that environmental justice is much more than an academic pursuit. “We’re not talking about climate change in the sense of statistics, infographics,” she said. “For us this is everyday life … [Future engineers and others training at MIT] should definitely take that into perspective, that these are real people really being affected by these injustices.”

    That call to action has already been felt by many at MIT.

    “I’ve been hearing from grad students lately, in engineering, saying, ‘I like thinking about these problems, but I don’t like where I’m being directed to use my intellectual capital, toward building more corporate wealth,’” said Kate Brown, professor of STS and an event organizer. “As an institution, we could move toward working not for, not to correct, but working with communities.”

    The world is what we’ve gotMIT senior Abdulazeez Mohammed Salim, an Aero/Astro major, says he was inspired by these conversations to get involved in urban farming initiatives in Baltimore, Maryland, where he plans to move after graduation.

    “We have a responsibility as part of the world around us, not as external observers, not as people removed and displaced from the world. And the world is not an experiment or a lab,” he says. “It’s what we’ve got. It’s who we are. It’s all that we’ve been and all we will be. That stuck with me; it resonated very deeply.”

    Salim also appreciated the reality check given by Bianca Bowman from GreenRoots Chelsea, who pointed out that success will not come quickly, and that sustained advocacy is critical.

    “Real, valuable change will not happen overnight, will not happen by just getting together a critical mass of people who are upset and concerned,” he said. “Because what we’re dealing with are large, interconnected, messy systems that will try to fight back and survive regardless of how we force them to adapt. And so, long term is really the only way forward. That’s the way we need to think of these struggles.” More

    MIT Climate and Sustainability Consortium announces recipients of inaugural MCSC Seed Awards

    The MIT Climate and Sustainability Consortium (MCSC) has awarded 20 projects a total of $5 million over two years in its first-ever 2022 MCSC Seed Awards program. The winning projects are led by principal investigators across all five of MIT’s schools.

    The goal of the MCSC Seed Awards is to engage MIT researchers and link the economy-wide work of the consortium to ongoing and emerging climate and sustainability efforts across campus. The program offers further opportunity to build networks among the awarded projects to deepen the impact of each and ensure the total is greater than the sum of its parts.

    For example, to drive progress under the awards category Circularity and Materials, the MCSC can facilitate connections between the technologists at MIT who are developing recovery approaches for metals, plastics, and fiber; the urban planners who are uncovering barriers to reuse; and the engineers, who will look for efficiency opportunities in reverse supply chains.

    “The MCSC Seed Awards are designed to complement actions previously outlined in Fast Forward: MIT’s Climate Action Plan for the Decade and, more specifically, the Climate Grand Challenges,” says Anantha P. Chandrakasan, dean of the MIT School of Engineering, Vannevar Bush Professor of Electrical Engineering and Computer Science, and chair of the MIT Climate and Sustainability Consortium. “In collaboration with seed award recipients and MCSC industry members, we are eager to engage in interdisciplinary exploration and propel urgent advancements in climate and sustainability.” 

    By supporting MIT researchers with expertise in economics, infrastructure, community risk assessment, mobility, and alternative fuels, the MCSC will accelerate implementation of cross-disciplinary solutions in the awards category Decarbonized and Resilient Value Chains. Enhancing Natural Carbon Sinks and building connections to local communities will require associations across experts in ecosystem change, biodiversity, improved agricultural practice and engagement with farmers, all of which the consortium can begin to foster through the seed awards.

    “Funding opportunities across campus has been a top priority since launching the MCSC,” says Jeremy Gregory, MCSC executive director. “It is our honor to support innovative teams of MIT researchers through the inaugural 2022 MCSC Seed Awards program.”

    The winning projects are tightly aligned with the MCSC’s areas of focus, which were derived from a year of highly engaged collaborations with MCSC member companies. The projects apply across the member’s climate and sustainability goals.

    The MCSC’s 16 member companies span many industries, and since early 2021, have met with members of the MIT community to define focused problem statements for industry-specific challenges, identify meaningful partnerships and collaborations, and develop clear and scalable priorities. Outcomes from these collaborations laid the foundation for the focus areas, which have shaped the work of the MCSC. Specifically, the MCSC Industry Advisory Board engaged with MIT on key strategic directions, and played a critical role in the MCSC’s series of interactive events. These included virtual workshops hosted last summer, each on a specific topic that allowed companies to work with MIT and each other to align key assumptions, identify blind spots in corporate goal-setting, and leverage synergies between members, across industries. The work continued in follow-up sessions and an annual symposium.

    “We are excited to see how the seed award efforts will help our member companies reach or even exceed their ambitious climate targets, find new cross-sector links among each other, seek opportunities to lead, and ripple key lessons within their industry, while also deepening the Institute’s strong foundation in climate and sustainability research,” says Elsa Olivetti, the Esther and Harold E. Edgerton Associate Professor in Materials Science and Engineering and MCSC co-director.

    As the seed projects take shape, the MCSC will provide ongoing opportunities for awardees to engage with the Industry Advisory Board and technical teams from the MCSC member companies to learn more about the potential for linking efforts to support and accelerate their climate and sustainability goals. Awardees will also have the chance to engage with other members of the MCSC community, including its interdisciplinary Faculty Steering Committee.

    “One of our mantras in the MCSC is to ‘amplify and extend’ existing efforts across campus; we’re always looking for ways to connect the collaborative industry relationships we’re building and the work we’re doing with other efforts on campus,” notes Jeffrey Grossman, the Morton and Claire Goulder and Family Professor in Environmental Systems, head of the Department of Materials Science and Engineering, and MCSC co-director. “We feel the urgency as well as the potential, and we don’t want to miss opportunities to do more and go faster.”

    The MCSC Seed Awards complement the Climate Grand Challenges, a new initiative to mobilize the entire MIT research community around developing the bold, interdisciplinary solutions needed to address difficult, unsolved climate problems. The 27 finalist teams addressed four broad research themes, which align with the MCSC’s focus areas. From these finalist teams, five flagship projects were announced in April 2022.

    The parallels between MCSC’s focus areas and the Climate Grand Challenges themes underscore an important connection between the shared long-term research interests of industry and academia. The challenges that some of the world’s largest and most influential companies have identified are complementary to MIT’s ongoing research and innovation — highlighting the tremendous opportunity to develop breakthroughs and scalable solutions quickly and effectively. Special Presidential Envoy for Climate John Kerry underscored the importance of developing these scalable solutions, including critical new technology, during a conversation with MIT President L. Rafael Reif at MIT’s first Climate Grand Challenges showcase event last month.

    Both the MCSC Seed Awards and the Climate Grand Challenges are part of MIT’s larger commitment and initiative to combat climate change; this was underscored in “Fast Forward: MIT’s Climate Action Plan for the Decade,” which the Institute published in May 2021.

    Amy Moran-Thomas receives the Edgerton Faculty Achievement Award

    Amy Moran-Thomas, the Alfred Henry and Jean Morrison Hayes Career Development Associate Professor of Anthropology, has received the 2021-22 Harold E. Edgerton Faculty Achievement Award in recognition of her “exceptional commitment to innovative and collaborative interdisciplinary approaches to resolving inequitable impacts on human health,” according to a statement by the  selection committee.A medical anthropologist, Moran-Thomas investigates linkages between human and environmental health, with a focus on health disparities. She is the author of the award-winning book “Traveling with Sugar: Chronicles of a Global Epidemic” (University of California Press, 2019), which frames the diabetes epidemic in Belize within the context of 500 years of colonialism.

    On human and planetary well-being Moran-Thomas “stands out in this field by bringing a humanistic approach into dialogue with environmental and science studies to investigate how bodily health is shaped by social well-being at the community level and further conditioned by localized planetary imbalances,” the selection committee’s statement said. “Professor Moran-Thomas shows how diabetes resides not only within human bodies but also across toxic environments, crumbling healthcare infrastructures, and stress-inducing economic inequalities.”Heather Paxson, the William R. Kenan, Jr. Professor of Anthropology and head of the MIT Anthropology program, calls Moran-Thomas “a fast-rising star in her field.” Paxson, who nominated Moran-Thomas for the award, adds, “She is also a highly effective teacher and student mentor, an engaged member of our Institute community, and a budding public intellectual.” A profound discovery for medical equity

    “Professor Moran-Thomas’s work has an extraordinarily profound and impactful reach,” according to the committee, which highlighted a widely read 2020 essay in Boston Review in which Moran-Thomas revealed that the fingertip pulse oximeter — a key tool in monitoring the effects of respiratory distress due to Covid-19 and other illness — gives misleading readings with darkly complected skin. This essay inspired a subsequent medical research study and ultimately led to an alert from the U.S. Food and Drug Administration spotlighting the limitations of pulse oximeters.

    The selection committee further lauded Moran-Thomas for her pedagogy, including her work developing the new subject 21A.311 (The Social Lives of Medical Objects). She was also commended for her service, notably her work on the MIT Climate Action Advisory Committee and with the Social and Ethical Responsibilities of Computing group within MIT’s Schwarzman College of Computing.

    Moran-Thomas earned her bachelor’s degree in literature from American University and her PhD in anthropology from Princeton University. She joined MIT Anthropology in 2015, following postdocs at the Woodrow Institute for Public and International Affairs and at Brown University’s Cogut Humanities Center. She was promoted to associate professor without tenure in 2019.

    The annual Edgerton Faculty Award, established in 1982 as a tribute to Institute Professor Emeritus Harold E. Edgerton, honors achievement in research, teaching, and service by a nontenured member of the faculty.The 2019-20 Edgerton Award Selection Committee was chaired by T.L. Taylor, a professor of Comparative Media Studies/Writing. Other members were Geoffrey Beach, a professor in the Department of Materials Science and Engineering; Mircea Dinca, the W.M. Keck Professor of Energy in the Department of Chemistry; Hazhir Rahmandad, an associate professor of system dynamics in the Sloan School of Management; and Rafi Segal, an associate professor in the Department of Architecture.

    Q&A: Bettina Stoetzer on envisioning a livable future

    In an ongoing series, MIT faculty, students, and alumni in the humanistic fields share perspectives that are significant for solving the economic, political, ethical, and cultural dimensions of climate change, as well as mitigating its myriad social and ecological impacts. Bettina Stoetzer is the Class of 1948 Career Development Associate Professor of Anthropology at MIT; her research combines perspectives on ecology and environmental change with an analysis of migration, race, and social justice. In this conversation with SHASS Communications, she shares insights from anthropology and from her forthcoming book, “Ruderal City: Ecologies of Migration and Urban Life in Berlin” (Duke University Press, 2022).Q: You research “ruderal” ecologies — those rising up like weeds in inhospitable locales such as industrial zones. What does your work reveal about the relationship between humans and the environment, particularly as climate change presents ever more challenges to human habitation?A: The term ruderal originates from the Latin word “rudus,” meaning “rubble.” In urban ecology it refers to organisms that spontaneously inhabit inhospitable environments such as rubble spaces, the cracks in sidewalks, or spaces alongside train tracks and roads. As an anthropologist, I find the ruderal to be a useful lens for examining this historical moment when environmental degradation, war, forced migration, economic inequality, and rising nationalism render much of the world inhospitable to so many beings.

    My book, “Ruderal City: Ecologies of Migration and Urban Life in Berlin,” is inspired by the insights of botany, ecology, as well as by social justice struggles. During my fieldwork in Berlin, I engaged with diverse communities — botanists, environmentalists, public officials, and other Berlin residents, such as white German nature enthusiasts, Turkish migrants who cultivate city gardens, and East African refugees who live in the forested edges of the city.The botanists I spoke with researched so-called “ruderal flora” that flourished in the city’s bombed landscapes after the end of World War II. Berlin’s rubble vegetation was abundant with plants that usually grow in much warmer climate zones, and the botanists realized that many of these plants’ seeds had arrived in the city by chance — hitching a ride via imported materials and vehicles, or the boots of refugees. At the same time, the initial appearance of these plants illustrated that Berlin had become hotter, which shed light on the early signs of climate change. But that is only part of the story. Listening to migrants, refugees, and other Berlin residents during my fieldwork, I also learned that it is important to consider the ways in which people who are often not recognized as experts relate to urban lands. White European environmental discourse often frames migrants and communities of color as having an inappropriate relation to “nature” in the city, and racializes them on that basis. For example, Turkish migrants who barbecue in Berlin’s parks are often portrayed as polluting the “green lungs” of Berlin.Yet from working with these communities, as well as with other Berliners who cultivated urban vegetable gardens, built makeshift shelters in abandoned lots, produced informal food economies in Berlin’s parks, or told stories about their experience in the forest edges of the city, I learned that people, while grappling with experiences of racism, actually carved out alternative ways of relating to urban lands that challenged white European and capitalist traditions.Engaging with these practices, I utilize the concept of the ruderal and expand it as an analytic for tracking seemingly disparate worlds — and for attending to the heterogeneous ways in which people build lives out of the ruins of European nationalism and capitalism. My goal in the book is not to equate people with plants, but rather to ask how people, plants, animals, and other living beings are intertwined in projects of capitalist extraction and in nation-making — and how they challenge and rework these projects.Q: In what ways do you think the tools and insights from anthropology can advance efforts to address climate change and its impacts?A: When tackling complex environmental challenges, climate change included, the focus is often on “the social consequences of” climate change and technological solutions to address it. What is exciting about anthropology is that it gives us tools to interrogate environmental challenges through a broader lens.Anthropologists use in-depth fieldwork to examine how people make sense of and relate to the world. Ethnographic fieldwork can help us examine how climate change affects people in their everyday lives, and it can reveal how different stakeholders approach environmental challenges. By providing a deeper understanding of the ways in which people relate to the material world, to land, and to other beings, anthropological analyses also shed light on the root causes of climate change and expand our imagination of how to live otherwise.Through these close-up analyses, ethnography can also illuminate large-scale political phenomena. For instance, by making visible the relation between climate change denial and the erosion of democratic social structures in people’s everyday lives, it can provide insights into the rise of nationalist and authoritarian movements. This is a question I explore in my new research project. (One case study in the new research focuses on the ways in which pigs, people, and viruses have co-evolved during urbanization, industrial agriculture, and the climate crisis, e.g.: the so-called African Swine Fever virus among wild boar — which proliferate in the ruins of industrial agriculture and climate changes — trigger political responses across Europe, including new border fences.)

    Through several case studies, I examine how the changing mobility patterns of wildlife (due to climate change, habitat loss, and urbanization) pose challenges for tackling the climate crisis across national borders and for developing new forms of care for nonhuman lives.Q: You teach MIT’s class 21A.407 (Gender, Race, and Environmental Justice). Broadly speaking, what are goals of this class? What lessons do you hope students will carry with them into the future?A: The key premise of this class is that the environmental challenges facing the world today cannot be adequately addressed without a deeper understanding of racial, gender, and class inequalities, as well as the legacies of colonialism. Our discussion begins with the lands on which we, at MIT, stand. We read about the colonization of New England and how it radically transformed local economies and landscapes, rearranged gender and racial relations, and led to the genocide and dispossession of Indigenous communities and their way of life.From this foundation, the goal is to expand our ideas of what it means to talk about ecology, the “environment,” and justice. There is not one way in which humans relate to land and to nonhuman beings, or one way of (re-)producing the conditions of our livelihoods (capitalism). These relations are all shaped by history, culture, and power.We read anthropological scholarship that explores how climate change, environmental pollution, and habitat destruction are also the consequences of modes of inhabiting the earth inherited from colonial relations to land that construct human and nonhuman beings as extractable “resources.” Considering these perspectives, it becomes clear that pressing environmental challenges can only be solved by also tackling racism and the legacies of colonialism.Throughout the semester, we read about environmental justice struggles that seek to stop the destruction of land, undo the harm of toxic exposures, and mitigate the effects of climate change. I hope that one of the takeaways students gain from this course is that Black, Indigenous, people-of-color, and feminist activists and scholars have been leading the way in shaping more livable futures.

    Q: In confronting an issue as formidable as global climate change, what gives you hope?A: I am really inspired by youth climate justice activists, especially from the Global South, who insist on new solutions to the climate emergency that counter market-driven perspectives, address global economic inequalities, and raise awareness about climate-driven displacement. Confronting climate change will require building more democratic structures and climate justice activists are at the forefront of this.Here at MIT, I also see a growing enthusiasm among our students to develop solutions to the climate crisis and to social injustices. I am particularly excited about Living Climate Futures, an initiative in Anthropology, History, and the Program on Science, Technology, and Society. We will be hosting a symposium at the end of April featuring environmental and climate justice leaders and youth activists from across the country. It will be a unique opportunity to explore how community leaders and research institutions such as MIT can collaborate more closely to tackle the challenges of climate change.
