What’s a park worth to the economy?
A first-of-its-kind study by University of Waterloo researchers has quantified the mental and physical health value of urban parks
The new framework developed by the researchers demonstrates the significant economic health savings and benefits from urban park investments.
In the first case study of its kind in Canada, researchers looked at Peterborough’s new Quaker Foods City Square, which cost taxpayers CAN$6.4m (~£3.8m), and have estimated the economic value of physical and mental health benefits that could come from it at more than CAN$4m 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 wellbeing, and as a means of cost savings to the medical system.
Jeffrey Wilson, professor in the School of Environment, Enterprise and Development at the University of Waterloo, said: “Investments in urban parks are among the soundest financial decisions a community can make.
“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 car lot to revitalise the downtown core of Peterborough.
The study’s estimated benefits of this new space represent only a portion of the value, as the researchers considered only a few benefits attributed to park use and vegetation cover.
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 rigour of the results and further quantify the return on urban park investments.
Wilson said: “Dollars drive decisions. 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.”
