Michigan has 2 of the 50 cities with the most green space per capita

Green space is beneficial anywhere, but especially in concrete jungles like those found in many U.S. cities. The World Health Organization reports that green areas are essential to both the ecosystem and the mental health of citizens; though the color is fading quickly in urban areas that are cutting down trees and rapidly building on open space. There are, however, some cities across America that are fighting hard to keep green space within their borders.

Using data from the Organization for Economic Co-operation and Development, analyzed by the United Nations Office for the Coordination of Humanitarian Affairs, Stacker considered the 70 U.S. cities with the most green space per capita and then ranked the top 50 by the green space areas devoted to parks and urban regions.

Read on to see which cities in your state made the list, or see the national story here.

#23. Grand Rapids

- Green space per capita: 18,177 sq. ft.
- Population: 194,352

Grand Rapids got a little greener in 2018, when the National Recreation and Parks Association donated $40,000 to the city for green space. The city also has a group dedicated to keeping it green. The Friends of Grand Rapids Parks works to make green spaces more inclusive by leading he Barbecue & Beautify series, a community-wide dinner, while also planting trees and providing green space education.

#17. Detroit

- Green space per capita: 22,572 sq. ft.
- Population: 682,669

A Toledo Blade editorial notes as the Detroit population declines, the city's green space grows, with up to 30 miles of vacant land available in the Motor City. For now, Lafayette Greens, an urban garden downtown, offers pollinator education and classes on raising butterflies, which draws many citizens to the green space. Residents can also enjoy downtown Detroit parks, including Beacon and Campus Martius that feature beach parties and concert series.

Some cities have gotten creative in constructing green space within their boundaries. Houston, Nashville, and Des Moines, Iowa, are among the many cities putting large green spaces on public rooftops. Atlanta even has plans to cover some of its highways with parks.

The former commissioner of the New York City Department of Parks and Recreation Adrian Benepe promotes the 10-Minute Walk campaign, an initiative to have a park within a 10-minute walk in all U.S. cities by 2050. Now the senior vice president for the Trust for Public Land, Benepe points to how green space helps the ecosystem. "When I see a tree, I see the work of God because a tree is a remarkable machine," Benepe said. "It does extraordinary things in exchange for very little."

What's more, the health benefits of parks and green spaces in cities are numerous, according to The National Recreation and Park Association. Large parks promote active living, which can reduce the risk of diabetes and heart disease, while research shows even small parks can reduce stress and improve creativity and mental health.
