Cities

David Zipper, a senior fellow at the MIT Mobility Lab, writes for Bloomberg about how the findings of William Whyte, an urbanist observer and writer, on what attracts people to urban spaces could be used to help draw people back to downtown areas after the Covid-19 pandemic. “Whyte’s insights suggest a need to build comfortable, pleasant places that invite people to linger, perhaps eating a meal or buying a new shirt while they’re there,” writes Zipper. “And his research serves as a reminder that good public spaces strengthen human relationships, offering an antidote to the loneliness epidemic said to afflict a growing number of Americans.”

Financial Times reporters Andrew Hill and Emma Jacobs spotlight how Prof. Carlo Ratti and his colleagues have found that “people are traveling less far from their homes, consistent with more remote working.” The findings demonstrate a more flexible approach to commuting. “That’s good news [for cities], because the problem is not a problem of capacity, it’s a problem of peaks,” Ratti explains.

New York Times reporter Stephen Wallis spotlights Prof. Carlo Ratti’s proposal for the world’s first “farmscraper” in Shenzhen, China, a 51-story building that would be wrapped in a vertical hydroponic farm and could produce enough food annually to feed 40,000 people. “At this critical moment, what we architects do matters more than ever,” Ratti emphasizes. “Every kilowatt-hour of solar power, every unit of zero-carbon housing and every calorie of sustainably sourced vegetables will be multiplied across history.”

Prof. Nathaniel Hendren and Prof. Justin Steil speak with New York Times reporter Jason DeParle about the difficulty in building affordable housing in opportunity-rich neighborhoods. “A lot has changed in American life over the past 50 years, but the hostility to affordable housing has remained surprisingly durable,” Steil explains. “Where you grow up matters a great deal for shaping your life outcomes,” Hendren adds.

Former postdoc Leah Ellis speaks with GBH All Things Considered host Arun Rath about   Sublime Systems, an MIT startup she co-founded that aims to produce carbon-free cement to combat climate change. “Sublime Systems and this technology spun out of my postdoctoral work at MIT,” says Ellis. “My co-founder and I are both electric chemists, so we have experience with battery technologies and electrochemical systems. Our idea was thinking about how we might use renewable energy—which we know has become more abundant, inexpensive and available—to eliminate the CO2 emissions from cement.”

David Zipper, Senior Fellow at the MIT Mobility Initiative, speaks with Washington Post reporter Trisha Thadani about the safety behind self-driving car companies, such as Google’s robotaxi service, Waymo.  Zipper says there is a disparity that “the companies are saying the technology is supposed to be a godsend for urban life, and it’s pretty striking that the leaders of these urban areas don’t really want them.”

Prof. Kent Larson speaks with Boston Globe reporter Scott Kirsner about City Science, a research group at the MIT Media Lab that studies urban development. Larson says “home manufacturers typically run into two problems: ‘negative stereotypes’ about prefabricated housing and unpredictable demand, which makes it difficult to keep a factory operating steadily,” writes Kirsner. 

Writing for The Boston Globe, Prof. Carlo Ratti addresses New York’s congestion pricing plan – an attempt to prevent traffic build up and improve public transportation – and ways Boston can develop a similar and more effective policy. “With congestion pricing, the city and state can combat the climate emergency, the cost of living crisis, and improve quality of life,” says Ratti. “If they don’t take action now, something even worse will come to pass: Boston will find itself outdone by New York.”

Writing for Bloomberg, Prof. Carlo Ratti and Arianna Salazar-Miranda SM '16, PhD '23 explore the possibility and potential of developing 15-minute cities in America. “If implemented correctly, the 15-minute city can be an agent of freedom: freedom from traffic jams, freedom to live in a healthy environment and freedom to be outside,” they write. “It is not a one-size-fits-all solution, but our research shows that almost every community in America could benefit from a few more well-placed amenities.”

Writing for The New York Times, Prof. Carlo Ratti and Harvard Prof. Edward L. Glaeser make the case that “the Bay Area needs a lot more housing, and we may need privately built cities to get there.” Ratti and Glaeser note, “building in the Bay Area will enable America to continue its history of allowing people to relocate to more productive places.”

Prof. Yet-Ming Chiang has been named to the TIME 100 Climate list, which highlights the world’s most influential climate leaders in business. “When it comes to cleantech, if it won’t scale, it doesn’t matter,” Chiang says. “This is a team sport—companies large and small, and governments state and federal, need to work together to get these new technologies out there where they can have impact.” 

Grace Colón PhD '95, a board member of the MIT Corporation, writes for The Hill about how to transform cities into biotech innovations hubs. “The best path to biotech success will be different for each city,” writes Colón. “But by building on institutional strengths, investing in workers, and knocking down barriers to success, there’s no reason more of them can’t get there.”

New York Times reporter Conor Dougherty spotlights DUSP graduate student Nick Allen MS '17 and his work advocating for Land-value taxes (LVT) in distressed US cities.

Writing for the Financial Times, Prof. Carlo Ratti explores the concept of the “15-minute city,” which is aimed at creating walkable neighborhoods. “The 15-minute city must be paired with investment in transport between neighborhoods,” writes Ratti, noting that investment is especially needed in public transportation to ensure that 15-minute cities do not contribute to greater segregation.

Roofscapes Studio, an MIT startup co-founded by Olivier Faber MArch ’23, Tim Cousin MArch ’23 and Eytan Levi MArch/MSRED ’21, transforms rooftops into greenspaces as part of an effort to combat climate change and provide green spaces in cities, reports Kim Willsher for The Guardian. The team is looking to add, “wooden platforms fixed across the sloping panes to create roof gardens, terraces and even walkways,” in Paris to help prevent the city from overheating.
