A new framework developed by the University of Waterloo researchers demonstrates the significant economic health savings and benefits from investments in green parks.
In the first case study of its kind in Canada, researchers looked at Peterborough’s new Quaker Foods City Square park, which cost taxpayers $6.4 million, and have estimated the economic value of physical and mental health benefits that could come from it at more than $4 million per year. The framework considers the health savings associated with improved mental health and better air quality, the avoided economic burden of physical inactivity and higher life satisfaction.
The study demonstrates the value of developing and enhancing urban parks as a strategy to improve population health and well-being and as a means of cost savings to the medical system.
Sound community investment
“Investments in urban parks are among the soundest financial decisions a community can make,” said Jeffrey Wilson, professor in the School of Environment, Enterprise and Development. “When you consider the population health benefits, the value of lessening climate-related impacts and the role of parks to support economic development, we see how parks provide a large payback.”
The park was developed on land previously used as a parking lot to revitalize the downtown core of Peterborough. The study’s estimated benefits of this new space represent only a portion of the park’s value, as the researchers considered only a few benefits attributed to park use and vegetation cover.
Multiple benefits from green parks
Future research could calculate other benefits such as respite from hot temperatures, relief from noise pollution, increased biodiversity, and social benefits resulting from stronger feelings of community cohesion, higher levels of community engagement, and reduced isolation. The researchers also identified other factors, such as socio-demographic, cultural variables, and urban design features, that could be included to increase the rigor of the results and further quantify the return on urban park investments.
“Dollars drive decisions,” said Wilson. “It can be challenging for decision-makers to support the development and expansion of urban parks because there are competing land use pressures, and municipalities are responsible for park operation and maintenance costs. However, this study offers concrete evidence that the health system savings alone justify the financial investment.”
