DURHAM, N.H.—Green space conversions to developed land are most common in areas where green space is already limited, according to new research released by the Carsey School of Public Policy at the University of New Hampshire.

While the research specifically looked at the Great Lakes states, the researchers found many of the trends are similar to what previous research has found in New England.

“The conversion of green space to development in New England is more likely to occur on the periphery of urban areas and in high amenity recreational areas, just as we found in the Great Lakes,” the researchers said. “Understanding how we use green space is critical because it contributes to air and water purification, storm abatement and enhanced human health and quality of life.”

The researchers also found that while population density strongly influences the conversion of green space to development, it is not the only factor. Population growth, the initial prevalence of green space and the area’s recreational or retirement appeal are also important.

“A better understanding of the links between demographic and land-cover change is crucial for future policy that works to balance development and green space conservation,” the researchers said.
