The Science Barge is a prototype, sustainable urban farm and environmental education center. It is the only fully functioning demonstration of renewable energy supporting sustainable food production in New York City. The Science Barge grows tomatoes, cucumbers, and lettuce with zero net carbon emissions, zero chemical pesticides, and zero runoff. From May to October 2007, the Science Barge hosted over 3,000 schoolchildren from all five New York boroughs as well as surrounding counties as part of our environmental education program. In addition, over 6,000 adult visitors visited the facility along with press from around the world.

The Science Barge: now in Yonkers, New York

The ownership of the Science Barge program has been assumed by Groundwork Hudson Valley, located in Yonkers, NY. For information about public tours, opening times and education programming, please follow this link to the Groundwork Hudson Valley website

“The Science Barge is not only an invitation to ideas and learning, but to change.”
Dr. Jeffrey Sachs, director of the Earth Institute at Columbia University
and special economic advisor to the United Nations.
