    Investing in Urban Forests

    As the state of Connecticut’s urban forester, Danica Doroski ’21 PhD is working with municipalities, nonprofits, and residents to grow and maintain urban forests. 

    “Investments in urban tree cover is a vital environmental justice issue,” Doroski says. “Urban areas with fewer trees can be as much as 20 degrees hotter than surrounding rural areas. By increasing tree cover, we can keep our cities cooler, which translates to both health and energy benefits.”

    Insights from the Night Sky

    Using data from the Visible Infrared Imaging Radiometer Suite aboard NASA’s Suomi NPP satellite spacecraft, Eleanor Stokes ’18 PhD is mapping disaster impacts in vulnerable communities. As co-leader of Black Marble, NASA’s first nighttime light dataset, Stokes has helped FEMA and other relief organizations direct their boots-on-the ground operations after natural disasters. “Humanity is facing major global risks from extreme weather and rising sea levels,” she says. “It’s very important to have a satellite record that can speak to the human piece of the puzzle.”

    Re-imagining Urban Tree Life

    Cambium Carbon, a startup company founded by Ben Christensen ’20 MEM and Marisa Repka ’20 MEM, is re-imagining the urban tree lifecycle — and combatting climate change in the process. The company is building  “reforestation hubs,” a unique private-public partnership that restores city forests across the U.S. Cambium Carbon received its initial funding from the Center for Business and the Environment at Yale and the Tsai Center for Innovative Thinking at Yale. It launched pilot reforestation hubs in four U.S. cities in 2021. It recently raised $3 million in seed funding that will allow it to reinvest in urban tree restoration and create local jobs.
