Green spaces could save millions in healthcare costs, study finds

ADELAIDE: Researchers from the University of Adelaide have highlighted how access to green spaces, such as national parks, could significantly reduce healthcare costs, with an estimated annual savings of $140 million for Adelaide alone. The study, published in Urban Forestry and Greening, underscores the health benefits associated with visiting natural areas, such as improved mental well-being and reduced chronic disease burdens.
Using mobile phone data from 2018-2019, the research analyzed visits to 20 national parks in Adelaide, combining this with survey data from over 1,000 park visitors. The findings reveal that green spaces contribute to better health outcomes, leading to reduced reliance on public and private healthcare services. These benefits are particularly relevant as urban populations grow and green spaces become increasingly essential for well-being.
However, access disparities exist, with lower socio-economic groups living three times farther from metropolitan parks than higher-income groups. These barriers not only perpetuate social inequalities but also hinder potential health benefits for disadvantaged communities. The researchers advocate for investments in green space infrastructure and equitable access to ensure all populations can reap these health benefits.
Further research is encouraged to explore how health system savings could be optimized through nature-focused urban planning and policies.
