    Two MIT films nominated for New England Emmy Awards

    Two films produced by MIT were honored with Emmy nominations by the National Academy of Television Arts & Sciences Boston/New England Chapter. Both “We Are the Forest” and “No Drop to Spare” illustrate international conversations the MIT community is having about the environment and climate change.“We Are the Forest,” produced by MIT Video Productions (MVP) at MIT Open Learning, was one of six nominees in the Education/Schools category. The documentary highlights the cultural and scientific exchange of the MIT Festival Jazz Ensemble, MIT Wind Ensemble, and MIT Vocal Jazz Ensemble in the Brazilian Amazon. The excursion depicted in the film was part of the ongoing work of Frederick Harris Jr., MIT director of wind and jazz ensembles and senior lecturer in music, to combine Brazilian music and environmental research.“No Drop to Spare,” created by the Department of Mechanical Engineering (MechE), was nominated in the Environment/Science and Video Essayist categories. The film, produced by John Freidah, MechE senior producer and creative lead, follows a team of researchers from the K. Lisa Yang Global Engineering and Research (GEAR) Center working in Kenya, Morocco, and Jordan to deploy affordable, user-driven smart irrigation technology.“We Are the Forest” tells the story of 80 MIT student musicians who traveled to Manaus, Brazil in March 2023. Together with Indigenous Brazilian musicians and activists, the students played music, created instruments with found objects from the rainforest, and connected their musical practice to nature and culture. The trip and the documentary culminated with the concert “Hearing Amazônia: Art and Resistance.”“We have an amazing team who are excited to tell the stories of so many great things that happen at MIT,” says Clayton Hainsworth, director for MVP. “It’s a true pleasure when we get to partner with the Institute’s community on these video projects — from Fred [Harris], with his desire for outreach of the music curriculum, giving students new perspectives and getting beyond the lab; to students getting to experience the world and seeing how that affects their next steps as they go out and make an impact.”The documentary was produced by Hainsworth, directed by Jean Dunoyer, staff editor at MVP, and filmed by Myles Lowery, field production videographer at MVP. Hainsworth credits Dunoyer with refining the story’s main themes: the universality of music as a common human language, and the ways that Indigenous communities can teach and inform the rest of the globe about the environment and the challenges we are all facing.“The film highlights the reach of how MIT touches the world and, more importantly, how the world touches MIT,” says Hainsworth, adding that the work was generously supported by A. Neil Pappalardo ’64 and Jane Pappalardo. “No Drop to Spare” evoked a similar sentiment from Freidah. “What I liked about this story was the potential for great impact,” says Freidah, discussing the MechE film’s production process. “It was global, it was being piloted in three different places in the world, with three different end users, and had three different applications. You sort of go in with an idea in mind of what the story might be, then things bubble up. In this story, as with so many stories, what rose to the top was the students and the impact they were having on the real world and end users.” Freidah has worked with Amos Winter SM ’05, PhD ’11, associate professor of mechanical engineering and MIT GEAR Center principal investigator, to highlight other impact global projects in the past, including producing a video in 2016. That film, “Water is Life,” explores the development of low-cost desalination systems in India. While the phrase “it’s an honor to be nominated” might seem cliched, it remains often used because the sentiment almost always rings true. Although neither film triumphed at this year’s awards ceremony, Freidah says there’s much to be celebrated in the final product. “Seeing the effect this piece had, and how it highlighted our students, that’s the success story — but it’s always nice also to receive recognition from outside.”The 47th Boston/New England Emmy Awards Ceremony took place on June 8 at the Marriott Boston Copley Place. A list of nominees and winners can be found on the National Academy of Television Arts and Sciences Boston/New England Chapter website.  More

    Making climate models relevant for local decision-makers

    Climate models are a key technology in predicting the impacts of climate change. By running simulations of the Earth’s climate, scientists and policymakers can estimate conditions like sea level rise, flooding, and rising temperatures, and make decisions about how to appropriately respond. But current climate models struggle to provide this information quickly or affordably enough to be useful on smaller scales, such as the size of a city. Now, authors of a new open-access paper published in the Journal of Advances in Modeling Earth Systems have found a method to leverage machine learning to utilize the benefits of current climate models, while reducing the computational costs needed to run them. “It turns the traditional wisdom on its head,” says Sai Ravela, a principal research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS) who wrote the paper with EAPS postdoc Anamitra Saha. Traditional wisdomIn climate modeling, downscaling is the process of using a global climate model with coarse resolution to generate finer details over smaller regions. Imagine a digital picture: A global model is a large picture of the world with a low number of pixels. To downscale, you zoom in on just the section of the photo you want to look at — for example, Boston. But because the original picture was low resolution, the new version is blurry; it doesn’t give enough detail to be particularly useful. “If you go from coarse resolution to fine resolution, you have to add information somehow,” explains Saha. Downscaling attempts to add that information back in by filling in the missing pixels. “That addition of information can happen two ways: Either it can come from theory, or it can come from data.” Conventional downscaling often involves using models built on physics (such as the process of air rising, cooling, and condensing, or the landscape of the area), and supplementing it with statistical data taken from historical observations. But this method is computationally taxing: It takes a lot of time and computing power to run, while also being expensive. A little bit of both In their new paper, Saha and Ravela have figured out a way to add the data another way. They’ve employed a technique in machine learning called adversarial learning. It uses two machines: One generates data to go into our photo. But the other machine judges the sample by comparing it to actual data. If it thinks the image is fake, then the first machine has to try again until it convinces the second machine. The end-goal of the process is to create super-resolution data. Using machine learning techniques like adversarial learning is not a new idea in climate modeling; where it currently struggles is its inability to handle large amounts of basic physics, like conservation laws. The researchers discovered that simplifying the physics going in and supplementing it with statistics from the historical data was enough to generate the results they needed. “If you augment machine learning with some information from the statistics and simplified physics both, then suddenly, it’s magical,” says Ravela. He and Saha started with estimating extreme rainfall amounts by removing more complex physics equations and focusing on water vapor and land topography. They then generated general rainfall patterns for mountainous Denver and flat Chicago alike, applying historical accounts to correct the output. “It’s giving us extremes, like the physics does, at a much lower cost. And it’s giving us similar speeds to statistics, but at much higher resolution.” Another unexpected benefit of the results was how little training data was needed. “The fact that that only a little bit of physics and little bit of statistics was enough to improve the performance of the ML [machine learning] model … was actually not obvious from the beginning,” says Saha. It only takes a few hours to train, and can produce results in minutes, an improvement over the months other models take to run. Quantifying risk quicklyBeing able to run the models quickly and often is a key requirement for stakeholders such as insurance companies and local policymakers. Ravela gives the example of Bangladesh: By seeing how extreme weather events will impact the country, decisions about what crops should be grown or where populations should migrate to can be made considering a very broad range of conditions and uncertainties as soon as possible.“We can’t wait months or years to be able to quantify this risk,” he says. “You need to look out way into the future and at a large number of uncertainties to be able to say what might be a good decision.”While the current model only looks at extreme precipitation, training it to examine other critical events, such as tropical storms, winds, and temperature, is the next step of the project. With a more robust model, Ravela is hoping to apply it to other places like Boston and Puerto Rico as part of a Climate Grand Challenges project.“We’re very excited both by the methodology that we put together, as well as the potential applications that it could lead to,” he says.  More

    Improving working environments amid environmental distress

    In less than a decade, MIT economist Namrata Kala has produced a corpus of work too rich, inventive, and diverse to be easily summarized. Let’s try anyway.Kala, an associate professor at the MIT Sloan School of Management, often studies environmental problems and their effects on workers and firms, with implications for government policy, corporate managers, and anyone concerned about climate change. She also examines the effects of innovation on productivity, from farms to factories, and scrutinizes firm organization in light of such major changes.Kala has published papers on topics including the long-term effects of climate change on agriculture in Africa and India; the impact of mechanization on farmers’ incomes; the extent to which linguistic differences create barriers to trade; and even the impact of LED light bulbs on factory productivity. Characteristically, Kala looks at issues of global scale and pinpoints their effects at the level of individuals.Consider one paper Kala and two colleagues published a couple of years ago, about the effects of air pollution on garment factory workers in India. The scholars examined patterns of particulate-matter pollution and linked that to detailed, worker-level data about how productive workers were along the production line. The study shows that air pollution damages sewing productivity, and that some managers (not all) are adept at recognizing which workers are most affected by it.What emerges from much of this work is a real-time picture of human adaptation in a time of environmental distress.“I feel like I’m part of a long tradition of trying to understand resilience and adaptation, but now in the face of a changing world,” Kala says. “Understanding interventions that are good for resilience while the world is changing is what motivates me, along with the fact that the vast majority of the world is vulnerable to events that may impact economic growth.”For her research and teaching, Kala was awarded tenure at MIT last year.Joining academia, then staying in itKala, who grew up in Punjab, India, was long mindful of big issues pertaining to society, the economy, and the environment.“Growing up in India, it’s very difficult not to be interested in the some of the questions that are important for development and environmental economics,” Kala says.However, Kala did not expect that interest to lead her into academia. She attended Delhi University as an undergraduate, earning her degree with honors in economics while expecting to find a job in the area of development. To help facilitate that, Kala enrolled in a one-year master’s program at Yale University, in international and development economics.Before that year was out, Kala had a new realization: Studying development problems was integral to solving them. Academia is not on the sidelines when it comes to development, but helps generate crucial knowledge to foster better and smarter growth policies.“I came to Yale for a one-year master’s because I didn’t know if I wanted to be in a university for another two years,” Kala says. “I wanted to work on problems in the world. And that’s when I became enthralled with research. It was this wonderful year where I could study anything, and it completely changed my perspective on what I could do next. So I did the PhD, and that’s how I became an economist.”After receiving her PhD in 2015, Kala spent the next two years supported by a Prize Fellowship in Economics, History, and Politics at Harvard University and a postdoctoral fellowship at MIT’s own Abdul Latif Jameel Poverty Action Lab (J-PAL). In 2017, she joined the MIT faculty on a full-time basis, and has remained at the Institute since then.The source material for Kala’s studies varies widely, though in all cases she is looking for ways to construct well-defined empirical studies tackling major questions, with key issues often revealed in policy or firm details.“I find reading stuff about policy reform strangely interesting,” she quips.Development, but with environmental qualityIndeed, sometimes the spark for Kala’s studies comes from her own broad knowledge of past policy reforms, combined with an ability to locate data that reveals their effects.For instance, one working paper Kala and a colleague recently completed looks at an Indian policy to move industrial firms out of Delhi in order to help solve the city’s pollution problems; the policy randomly relocated companies in an industrial belt around the city. But what effect did this have on the firms? After examining the records of 20,000 companies, the researchers found these firms’ survival rate was 8 percent to 20 percent lower than if the policy called for them to be clustered more efficiently.That finding suggests how related environmental policies can be designed in the future.“This environmental policy was important in that it improved air quality in Delhi, but there’s a way to do that which also reduces the cost on firms,” Kala says.Kala says she expects India to be the locus of many, though hardly all, of her future studies. The country provides a wide range of opportunities for research.“India currently has both the largest number of poor people in the world as well as 21 of the 30 most polluted cities in the world,” Kala says. “Clearly, the tradeoff between development and environmental quality is extremely salient, and we need progress in understanding industrial policies that are at least environmentally neutral or improving environmental quality.”Kala will continue to look for new ways to take pressing, large-scale issues and study their effects in daily life. But the fact that her work ranges so widely is not just due to the places she studies; it is also because of the place she studies them from. MIT, she believes, has provided her with an environment of its own, which in this case enhances her own productivity.“One thing that helps a lot is having colleagues and co-authors to bounce ideas of off,” Kala says. “Sloan is the heart of so much interdisciplinary work. That is one big reason why I’ve had a broad set of interests and continue to work on many things.”“At Sloan,” she adds, “there are people doing fascinating things that I’m happy to listen to, as well as people in different disciplines working on related things who have a perspective I find extremely enriching. There are excellent economists, but I also go into seminars about work or productivity or the environment and come away with a perspective I don’t think I could have come up with myself.” More

    Microscopic defects in ice influence how massive glaciers flow, study shows

    As they seep and calve into the sea, melting glaciers and ice sheets are raising global water levels at unprecedented rates. To predict and prepare for future sea-level rise, scientists need a better understanding of how fast glaciers melt and what influences their flow.Now, a study by MIT scientists offers a new picture of glacier flow, based on microscopic deformation in the ice. The results show that a glacier’s flow depends strongly on how microscopic defects move through the ice.The researchers found they could estimate a glacier’s flow based on whether the ice is prone to microscopic defects of one kind versus another. They used this relationship between micro- and macro-scale deformation to develop a new model for how glaciers flow. With the new model, they mapped the flow of ice in locations across the Antarctic Ice Sheet.Contrary to conventional wisdom, they found, the ice sheet is not a monolith but instead is more varied in where and how it flows in response to warming-driven stresses. The study “dramatically alters the climate conditions under which marine ice sheets may become unstable and drive rapid rates of sea-level rise,” the researchers write in their paper.“This study really shows the effect of microscale processes on macroscale behavior,” says Meghana Ranganathan PhD ’22, who led the study as a graduate student in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS) and is now a postdoc at Georgia Tech. “These mechanisms happen at the scale of water molecules and ultimately can affect the stability of the West Antarctic Ice Sheet.”“Broadly speaking, glaciers are accelerating, and there are a lot of variants around that,” adds co-author and EAPS Associate Professor Brent Minchew. “This is the first study that takes a step from the laboratory to the ice sheets and starts evaluating what the stability of ice is in the natural environment. That will ultimately feed into our understanding of the probability of catastrophic sea-level rise.”Ranganathan and Minchew’s study appears this week in the Proceedings of the National Academy of Sciences.Micro flowGlacier flow describes the movement of ice from the peak of a glacier, or the center of an ice sheet, down to the edges, where the ice then breaks off and melts into the ocean — a normally slow process that contributes over time to raising the world’s average sea level.In recent years, the oceans have risen at unprecedented rates, driven by global warming and the accelerated melting of glaciers and ice sheets. While the loss of polar ice is known to be a major contributor to sea-level rise, it is also the biggest uncertainty when it comes to making predictions.“Part of it’s a scaling problem,” Ranganathan explains. “A lot of the fundamental mechanisms that cause ice to flow happen at a really small scale that we can’t see. We wanted to pin down exactly what these microphysical processes are that govern ice flow, which hasn’t been represented in models of sea-level change.”The team’s new study builds on previous experiments from the early 2000s by geologists at the University of Minnesota, who studied how small chips of ice deform when physically stressed and compressed. Their work revealed two microscopic mechanisms by which ice can flow: “dislocation creep,” where molecule-sized cracks migrate through the ice, and “grain boundary sliding,” where individual ice crystals slide against each other, causing the boundary between them to move through the ice.The geologists found that ice’s sensitivity to stress, or how likely it is to flow, depends on which of the two mechanisms is dominant. Specifically, ice is more sensitive to stress when microscopic defects occur via dislocation creep rather than grain boundary sliding.Ranganathan and Minchew realized that those findings at the microscopic level could redefine how ice flows at much larger, glacial scales.“Current models for sea-level rise assume a single value for the sensitivity of ice to stress and hold this value constant across an entire ice sheet,” Ranganathan explains. “What these experiments showed was that actually, there’s quite a bit of variability in ice sensitivity, due to which of these mechanisms is at play.”A mapping matchFor their new study, the MIT team took insights from the previous experiments and developed a model to estimate an icy region’s sensitivity to stress, which directly relates to how likely that ice is to flow. The model takes in information such as the ambient temperature, the average size of ice crystals, and the estimated mass of ice in the region, and calculates how much the ice is deforming by dislocation creep versus grain boundary sliding. Depending on which of the two mechanisms is dominant, the model then estimates the region’s sensitivity to stress.The scientists fed into the model actual observations from various locations across the Antarctic Ice Sheet, where others had previously recorded data such as the local height of ice, the size of ice crystals, and the ambient temperature. Based on the model’s estimates, the team generated a map of ice sensitivity to stress across the Antarctic Ice Sheet. When they compared this map to satellite and field measurements taken of the ice sheet over time, they observed a close match, suggesting that the model could be used to accurately predict how glaciers and ice sheets will flow in the future.“As climate change starts to thin glaciers, that could affect the sensitivity of ice to stress,” Ranganathan says. “The instabilities that we expect in Antarctica could be very different, and we can now capture those differences, using this model.”  More

    New MIT-LUMA Lab created to address climate challenges in the Mediterranean region

    The MIT School of Architecture and Planning (SA+P) and the LUMA Foundation announced today the establishment of the MIT-LUMA Lab to advance paradigm-shifting innovations at the nexus of art, science, technology, conservation, and design. The aim is to empower innovative thinkers to realize their ambitions, support local communities as they seek to address climate-related issues, and scale solutions to pressing challenges facing the Mediterranean region.  The main programmatic pillars of the lab will be collaborative scholarship and research around design, new materials, and sustainability; scholar exchange and education collaborations between the two organizations; innovation and entrepreneurship activities to transfer new ideas into practical applications; and co-production of exhibitions and events. The hope is that this engagement will create a novel model for other institutions to follow to craft innovative solutions to the leading challenge of our time.The MIT-LUMA Lab draws on an establishing gift from the LUMA Foundation, a nonprofit organization based in Zurich formed by Maja Hoffmann in 2004 to support contemporary artistic production. The foundation supports a range of multidisciplinary projects that increase understanding of the environment, human rights, education, and culture.These themes are explored through programs organized by LUMA Arles, a project begun in 2013 and housed on a 27-acre interdisciplinary campus known as the Parc des Ateliers in Arles, France, an experimental site of exhibitions, artists’ residencies, research laboratories, and educational programs.“The Luma Foundation is committed to finding ways to address the current climate emergencies we are facing, focusing on exploring the potentials that can be found in diversity and engagement in every possible form,” says Maja Hoffmann, founder and president of the LUMA Foundation. “Cultural diversity, pluralism, and biodiversity feature at the top of our mission and our work is informed by these concepts.” A focus on the Mediterranean region“The culturally rich area of the Mediterranean, which has produced some of the most remarkable civilizational paradigms across geographies and historical periods, plays an important role in our thinking. Focusing the efforts of the MIT-LUMA Lab on the Mediterranean means extending the possibilities for positive change throughout other global ecosystems,” says Hoffmann. “Our projects of LUMA Arles and its research laboratory on materials and natural resources, the Atelier Luma, our position in one of Europe’s most important natural reserves, in conjunction with the expertise and forward-thinking approach of MIT, define the perfect framework that will allow us to explore new frontiers and devise novel ways to tackle our most significant civilizational risks,” she adds. “Supporting the production of new forms of knowledge and practices, and with locations in Cambridge and in Arles, our collaboration and partnership with MIT will generate solutions and models for the future, for the generations to come, in order to provide them the same and even better opportunities that what we have experienced.”“We know we do not have all the answers at MIT, but we do know how to ask the right questions, how to design effective experiments, and how to build meaningful collaborations,” says Hashim Sarkis, dean of SA+P, which will host the lab. “I am grateful to the LUMA Foundation for offering support for faculty research deployment designed to engage local communities and create jobs, for course development to empower our faculty to teach classes centered on these issues, and for students who seek to dedicate their lives and careers to sustainability. We also look forward to hosting fellows and researchers from the foundation to strengthen our collaboration,” he adds.The Mediterranean region, the MIT-LUMA Lab’s focus, is one of the world’s most vital and fragile global commons. The future of climate relies on the sustainability of the region’s forests, oceans, and deserts that have for millennia created the environmental conditions and system-regulating functions necessary for life on Earth. Those who live in these areas are often the most severely affected by even relatively modest changes in the climate. Climate research and action: A priority at MITTo reverse negative trends and provide a new approach to addressing the climate crisis in these vast areas, SA+P is establishing international collaborations that bring know-how to the field, and in turn to learn from the communities and groups most challenged by climate impacts.The MIT-LUMA Lab is the first in what is envisioned as a series of regionally focused labs at SA+P under the conceptual aegis of a collaborative platform called Our Global Commons. This project will support progress on today’s climate challenges by focusing on community empowerment, long-term local collaborations around research and education, and job creation. Faculty-led fieldwork, engagements with local stakeholders, and student involvement will be the key elements.The creation of Our Global Commons comes as MIT works to dramatically expand its efforts to address climate change. In February 2024, President Sally Kornbluth announced the Climate Project at MIT, a major new initiative to mobilize the Institute’s resources and capabilities to research, develop, deploy, and scale-up new climate solutions. The Institute will hire its first-ever vice president for climate to oversee the new effort. “With the Climate Project at MIT, we aim to help make a decisive difference, at scale, on crucial global climate challenges — and we can only do that by engaging with outstanding colleagues around the globe,” says Kornbluth. “By connecting us to creative thinkers steeped in the cultural and environmental history and emerging challenges of the Mediterranean region, the MIT-LUMA Lab promises to spark important new ideas and collaborations.”“We are excited that the LUMA team will be joining in MIT’s engagement with climate issues, especially given their expertise in advancing vital work at the intersection of art and science, and their long-standing commitment to expanding the frontiers of sustainability and biodiversity,” says Sarkis. “With climate change upending many aspects of our society, the time is now for us to reaffirm and strengthen our SA+P tradition of on-the-ground work with and for communities around the world. Shared efforts among local communities, governments and corporations, and academia are necessary to bring about real change.” More

    Sophia Chen: It’s our duty to make the world better through empathy, patience, and respect

    Sophia Chen, a fifth-year senior double majoring in mechanical engineering and art and design, learned about MIT D-Lab when she was a Florida middle schooler. She drove with her family from their home in Clearwater to Tampa to an MIT informational open house for prospective students. There, she heard about a moringa seed press that had been developed by D-Lab students. Those students, Kwami Williams ’12 and Emily Cunningham (a cross-registered Harvard University student), went on to found MoringaConnect with a goal of increasing Ghanaian farmer incomes. Over the past 12 years, the company has done just that, sometimes by a factor of 10 or more, by selling to wholesalers and establishing their own line of moringa skin and hair care products, as well as nutritional supplements and teas.“I remember getting chills,” says Sophia. “I was so in awe. MIT had always been my dream college growing up, but hearing this particular story truly cemented that dream. I even talked about D-Lab during my admissions interview. Once I came to MIT, I knew I had to take a D-Lab class — and now, at the end of my five years, I’ve taken four.”Taking four D-Lab classes during her undergraduate years may make Sophia exceptional, though not unusual. Of the nearly 4,000 enrollments in D-Lab classes over the past 22 years, as many as 20 percent took at least two classes, and many take three or more by the time the graduate. For Sophia, her D-Lab classes were a logical progression that both confirmed and expanded her career goals in global medicine.Centering the role of project community partnersSophia’s first D-Lab class was 2.722J / EC.720 (D-Lab: Design). Like all D-Lab classes, D-Lab: Design is project-based and centers the knowledge and contributions of each project’s community partner. Her team worked with a group in Uganda called Safe Water Harvesters on a project aimed at creating a solar-powered atmospheric water harvester using desiccants. They focused on early research and development for the desiccant technology by running tests for vapor absorption. Safe Water Harvesters designed the parameters and goals of the project and collaborated with the students remotely throughout the semester.Safe Water Harvesters’ role in the project was key to the project’s success. “At D-Lab, I learned the importance of understanding that solutions in international development must come from the voices and needs of people whom the intervention is trying to serve,” she says. “Some of the first questions we were taught to ask are ‘what materials and manufacturing processes are available?’ and ‘how is this technology going to be maintained by the community?’”The link between water access and gender inequityElecting to join the water harvesting project in Uganda was no accident. The previous summer, Sophia had interned with a startup targeting the spread of cholera in developing areas by engineering a new type of rapid detection technology that would sample from users’ local water sources. From there, she joined Professor Amos Winter’s Global Engineering and Research (GEAR) Lab as an Undergraduate Research Opportunities Program student and worked on a point-of-use desalination unit for households in India. Taking EC.715 (D-Lab: Water, Sanitation, and Hygiene) was a logical next step for Sophia. “This class was life-changing,” she says. “I was already passionate about clean water access and global resource equity, but I quickly discovered the complexity of WASH not just as an issue of poverty but as an issue of gender.” She joined a project spearheaded by a classmate from Nepal, which aimed to address the social taboos surrounding menstruation among Nepalese schoolgirls.“This class and project helped me realize that water insecurity and gender inequality — especially gender-based violence — ​are highly intertwined,” comments Sophia. This plays out in a variety of ways. Where there is poor sanitation infrastructure in schools, girls often miss classes or drop out altogether when menstruating. And where water is scarce, women and girls often walk miles to collect water to accommodate daily drinking, cooking, and hygiene needs. During this trek, they are vulnerable to assault and the pressure to engage in transactional sex at water access points.“It became clear to me that women are disproportionately affected by water insecurity, and that water is key to understanding women’s empowerment,” comments Sophia, “and that I wanted to keep learning about the field of development and how it intersects with gender!”So, in fall 2023, Sophia took both 11.025/EC.701 (D-Lab: Development) and WGS.277/EC.718 (D-Lab: Gender and Development). In D-Lab: Development, her team worked with Tatirano, a nongovernmental organization in Madagascar, to develop a vapor-condensing chamber for a water desalination system, a prototype they were able to test and iterate in Madagascar at the end of the semester.Getting out into the world through D-Lab fieldwork“Fieldwork with D-Lab is an eye-opening experience that anyone could benefit from,” says Sophia. “It’s easy to get lost in the MIT and tech bubble. But there’s a whole world out there with people who live such different lives than many of us, and we can learn even more from them than we can from our psets.”For Sophia’s D-Lab: Gender and Development class, she worked with the Society Empowerment Project in Kenya, ultimately traveling there during MIT’s Independent Activities Period last January. In Kenya, she worked with her team to run a workshop with teen parents to identify risk factors prior to pregnancy and postpartum challenges, in order to then ideate and develop solutions such as social programs. “Through my fieldwork in Kenya and Madagascar,” says Sophia, “it became clear how important it is to create community-based solutions that are led and maintained by community members. Solutions need community input, leadership, and trust. Ultimately, this is the only way to have long-lasting, high-impact, sustainable change. One of my D-Lab trip leaders said that you cannot import solutions. I hope all engineers recognize the significance of this statement. It is our duty as engineers and scientists to make the world a better place while carrying values of empathy, patience, and respect.”Pursuing passion and purpose at the intersection of medicine, technology, and policyAfter graduation in June, Sophia will be traveling to South Africa through MISTI Africa to help with a clinical trial and community outreach. She then intends to pursue a master’s in global health and apply to medical school, with the goal of working in global health at the intersection of medicine, technology, and policy.“It is no understatement to say that D-Lab has played a central role in helping me discover what I’m passionate about and what my purpose is in life,” she says. “I hope to dedicate my career towards solving global health inequity and gender inequality.” ​ More

    Convening for cultural change

    Whether working with fellow students in the Netherlands to design floating cities or interning for a local community-led environmental justice organization, Cindy Xie wants to help connect people grappling with the implications of linked social and environmental crises.The MIT senior’s belief that climate action is a collective endeavor grounded in systems change has led her to work at a variety of community organizations, and to travel as far as Malaysia and Cabo Verde to learn about the social and cultural aspects of global environmental change.“With climate action, there is such a need for collective change. We all need to be a part of creating the solutions,” she says.Xie recently returned from Kuala Lumpur, where she attended the Planetary Health Annual Meeting hosted by Sunway University, and met researchers, practitioners, and students from around the world who are working to address challenges facing human and planetary health.Since January 2023, Xie has been involved with the Planetary Health Alliance, a consortium of organizations working at the intersection of human health and global environmental change. As a campus ambassador, she organized events at MIT that built on students’ interests in climate change and health while exploring themes of community and well-being.“I think doing these events on campus and bringing people together has been my way of trying to understand how to put conceptual ideas into action,” she says.Grassroots community-buildingAn urban studies and planning major with minors in anthropology and biology, Xie is also earning her master’s degree in city planning in a dual degree program, which she will finish next year.Through her studies and numerous community activities, she has developed a multidimensional view of public health and the environment that includes spirituality and the arts as well as science and technology. “What I appreciate about being here at MIT is the opportunities to try to connect the sciences back to other disciplines,” she says.As a campus ambassador for the Planetary Health Alliance, Xie hosted a club mixer event during Earth Month last year, that brought together climate, health, and social justice groups from across the Institute. She also created a year-long series that concluded its final event last month, called Cultural Transformation for Planetary Health. Organized with the Radius Forum and other partners, the series explored social and cultural implications of the climate crisis, with a focus on how environmental change affects health and well-being.Xie has also worked with the Planetary Health Alliance’s Constellation Project through a Public Service Fellowship from the PKG Center, which she describes as “an effort to convene people from across different areas of the world to talk about the intersections of spirituality, the climate, and environmental change and planetary health.”She has also interned at the Comunidades Enraizadas Community Land Trust, the National Institutes of Health, and the World Wildlife Fund U.S. Markets Institute. And, she has taken her studies abroad through MIT International Science and Technology Initiatives (MISTI). In 2023 she spent her Independent Activities Period in a pilot MISTI Global Classroom program in Amsterdam, and in the summer of 2023, she spent two months in Cabo Verde helping to start a new research collaboration tracking the impacts of climate change on human health.The power of storytellingGrowing up, Xie was drawn to storytelling as a means of understanding the intersections of culture and health within diverse communities. This has largely driven her interest in medical anthropology and medical humanities, and impacts her work as a member of the Asian American Initiative.The AAI is a student-led organization that provides a space for pan-Asian advocacy and community building on campus. Xie joined the group in 2022 and currently serves as a member of the executive board as well as co-leader of the Mental Health Project Team. She credits this team with inspiring discussions on holistic framings of mental health.“Conversations on mental health stigma can sometimes frame it as a fault within certain communities,” she says. “It’s also important to highlight alternate paradigms for conceptualizing mental health beyond the highly individualized models often presented in U.S. higher education settings.”Last spring, the AAI Mental Health team led a listening tour with Asian American clinicians, academic experts, and community organizations in Greater Boston, expanding the group’s connections. That led the group to volunteer last November at the Asian Mental Health Careers Day, hosted by the Let’s Talk! Conference at the Harvard Graduate School of Education. In March, the club also traveled to Yale University to participate in the East Coast Asian American Student Union Conference alongside hundreds of attendees from different college campuses.On campus, the team hosts dialogue events where students convene in an informal setting to discuss topics such as family ties and burnout and overachievement. Recently, AAI also hosted a storytelling night in partnership with MIT Taara and the newly formed South Asian Initiative. “There’s been something really powerful about being in those kinds of settings and building collective stories among peers,” Xie says.Community connectionsWriting, both creative and non-fiction, is another of Xie’s longstanding interests. From 2022 to 2023, she wrote for The Yappie, a youth-led news publication covering Asian American and Pacific Islander policy and politics. She has also written articles for The Tech, MIT Science Policy Review, MISTI Blogs, and more. Last year, she was a spread writer for MIT’s fashion publication, Infinite Magazine, for which she interviewed the founder of a local streetwear company that aims to support victims of sexual violence in the Democratic Republic of Congo.This year, she performed a spoken word piece in the “MIT Monologues,” an annual production at MIT that features stories of gender, relationships, race, and more. Her poetry was recently published in Sine Theta and included in MassPoetry’s 2024 Intercollegiate Showcase. Xie has previously been involved in the a capella group MIT Muses and enjoys live music and concerts as well. Tapping into her 2023 MISTI experience, Xie recently went to the concert of a Cabo Verdean artist at the Strand Theatre in Dorchester. “The crowd was packed,” she says. “It was just like being back in Cabo Verde. I feel very grateful to have seen these local connections.”After graduating, Xie hopes to continue building interdisciplinary connections. “I’m interested in working in policy or academia or somewhere in between the two, sort of around this idea of partnership and alliance building. My experiences abroad during my time at MIT have also made me more interested in working in an international context in the future.” More

    Q&A: The power of tiny gardens and their role in addressing climate change

    To address the climate crisis, one must understand environmental history. MIT Professor Kate Brown’s research has typically focused on environmental catastrophes. More recently, Brown has been exploring a more hopeful topic: tiny gardens.Brown is the Thomas M. Siebel Distinguished Professor in History of Science in the MIT Program in Science, Technology, and Society. In this Q&A, Brown discusses her research, and how she believes her current project could help put power into the hands of everyday people.This is part of an ongoing series exploring how the MIT School of Humanities, Arts, and Social Sciences is addressing the climate crisis.Q: You have created an unusual niche for yourself as an historian of environmental catastrophes. What drew you to such a dismal beat?A: Historians often study New York, Warsaw, Moscow, Berlin, but if you go to these little towns that nobody’s ever heard of, that’s where you see the destruction in the wake of progress. This is likely because I grew up in a manufacturing town in the Midwestern Rust Belt, watching stores go bankrupt and houses sit empty. I became very interested in the people who were the last to turn off the lights.Q: Did this interest in places devastated by technological and economic change eventually lead to your investigation of Chernobyl?A: I first studied the health and environmental consequences of radioactive waste on communities near nuclear weapons facilities in the U.S. and Russia, and then decided to focus on the health and environmental impacts of fallout from the Chernobyl nuclear energy plant disaster. After gaining access to the KGB records in Kiev, I realized that there was a Klondike of records describing what Soviet officials at the time called a “public health disaster.” People on the ground recognized the saturation of radioactivity into environments and food supplies not with any with sensitive devices, but by noticing the changes in ecologies and on human bodies. I documented how Moscow leaders historically and decades later engaged in a coverup, and that even international bodies charged with examining nuclear issues were reluctant to acknowledge this ongoing public health disaster due to liabilities in their own countries from the production and testing of nuclear weapons during the Cold War.Q: Why did you turn from detailed studies of what you call “modernist wastelands” to the subject of climate change?A: Journalists and scholars have worked hard in the last two decades to get people to understand the scope and the scale and the verisimilitude of climate change. And that’s great, but some of these catastrophic stories we tell don’t make people feel very safe or secure. They have a paralyzing effect on us. Climate change is one of many problems that are too big for any one person to tackle, or any one entity, whether it’s a huge nation like the United States or an international body like the U.N.So I thought I would start to work on something that is very small scale that puts action in the hands of just regular people to try to tell a more hopeful story. I am finishing a new book about working-class people who got pushed off their farms in the 19th century, and ended up in mega cities like London, Berlin, Amsterdam, and Washington D.C., find land on the periphery of the cities. They start digging, growing their own food, cooperating together. They basically recreated forms of the commons in cities. And in so doing, they generate the most productive agriculture in recorded history.Q: What are some highlights of this extraordinary city-based food generation?A: In Paris circa 1900, 5,000 urban farmers grew fruits and vegetables and fresh produce for 2 million Parisians with a surplus left over to sell to London. They would plant three to six crops a year on one tract of land using horse manure to heat up soils from below to push the season and grow spring crops in winter and summer crops in spring.An agricultural economist looked at the inputs and the outputs from these Parisian farms. He found there was no comparison to the Green Revolution fields of the 1970s. These urban gardeners were producing far more per acre, with no petroleum-based fertilizers.Q: What is the connection between little gardens like these and the global climate crisis, where individuals can feel at loss facing the scale of the problems?A: You can think of a tiny city garden like a coral reef, where one little worm comes and builds its cave. And then another one attaches itself to the first, and so on. Pretty soon you have a great coral reef with a platform to support hundreds of different species — a rich biodiversity. Tiny gardens work that way in cities, which is one reason cities are now surprising hotspots of biodiversity.Transforming urban green space into tiny gardens doesn’t take an act of God, the U.N., or the U.S. Congress to make a change. You could just go to your municipality and say, “Listen, right now we have a zoning code that says every time there’s a new condo, you have to have one or two parking spaces, but we’d rather see one or two garden spaces.”And if you don’t want a garden, you’ll have a neighbor who does. So people are outside and they have their hands in the soil and then they start to exchange produce with one another. As they share carrots and zucchini, they exchange soil and human microbes as well. We know that when people share microbiomes, they get along better, have more in common. It comes as no surprise that humans have organized societies around shaking hands, kissing on the cheek, producing food together and sharing meals. That’s what I think we’ve lost in our remote worlds.Q: So can we address or mitigate the impacts of climate change on a community-by-community basis?A: I believe that’s probably the best way to do it. When we think of energy we often imagine deposits of oil or gas, but, as our grad student Turner Adornetto points out, every environment has energy running through it. Every environment has its own best solution. If it’s a community that lives along a river, tap into hydropower; or if it’s a community that has tons of organic waste, maybe you want to use microbial power; and if it’s a community that has lots of sun then use different kinds of solar power. The legacy of midcentury modernism is that engineers came up with one-size-fits-all solutions to plug in anywhere in the world, regardless of local culture, traditions, or environment. That is one of the problems that has gotten us into this fix in the first place.Politically, it’s a good idea to avoid making people feel they’re being pushed around by one set of codes, one set of laws in terms of coming up with solutions that work. There are ways of deriving energy and nutrients that enrich the environment, ways that don’t drain and deplete. You see that so clearly with a plant, which just does nothing but grow and contribute and give, whether it’s in life or in death. It’s just constantly improving its environment.Q: How do you unleash creativity and propagate widespread local responses to climate change?A: One of the important things we are trying to accomplish in the humanities is communicating in the most down-to-earth ways possible to our students and the public so that anybody — from a fourth grader to a retired person — can get engaged.There’s “TECHNOLOGY” in uppercase letters, the kind that is invented and patented in places like MIT. And then there’s technology in lowercase letters, where people are working with things readily at hand. That is the kind of creativity we don’t often pay enough attention to.Keep in mind that at the end of the 19th century, scientists were sure that the earth was cooling and the earth would all under ice by 2020. In the 1950s, many people feared nuclear warfare. In the 1960s the threat was the “population bomb.” Every generation seems to have its apocalyptic sense of doom. It is helpful to take climate change and the Anthropocene and put them in perspective. These are problems we can solve. More
