How Thinking Like a Watershed System can Help Save Narragansett Bay

The Narragansett Bay, which covers almost 150 square miles along the coast of Rhode Island and Massachusetts, is New England’s largest estuary, and it is under threat from both changing patterns of land use in New England and global climate change. Recently, researchers at the University of Massachusetts Amherst published the results of a new study that connects land use, the coast and the climate, to identify various workable interventions that could guide the Bay’s restoration.

“I grew up on Narragansett Bay, 1,500 feet from the water,” says Evan Ross, senior lecturer in UMass Amherst’s College of Natural Science and the paper’s lead author. “In 2003, I saw a massive fish kill, which resulted from nutrient runoff, and I’ve watched as Rhode Island has made significant investments in protecting the bay.” But, as Ross and his co-author, Timothy Randhir, professor of environmental conservation at UMass Amherst, argue, conservation efforts may be wasted if they don’t take into account future stress caused by climate change and development. Furthermore, a full account of the Bay’s future must look beyond the Bay itself, which is why Ross and Randhir rely on what they call a “system-based” approach to their research.

A system-based approach acknowledges the reality of interaction. A bay is more than just the body of water in it. It is connected to all the rivers and streams that flow into it, the land through which those rivers and streams run, and the climate that influences everything from rainfall patterns to surface temperatures. “A systems approach should be considered for all environmental problems,” says Randhir, though managing the enormous amounts of data and variables means that a system-based approach brings with it great complexity.
