Spending time in green spaces—such as parks, gardens, and natural landscapes—has been shown to improve physical and mental health and encourage more sustainable lifestyles. However, many people, especially in disadvantaged communities, have faced barriers to access due to safety concerns, time constraints, and limited availability. This project examined how Green Social Prescriptions (GSPs)—structured programs like nature walks, community gardening, and forest bathing—can help bridge this gap by providing equitable, supported ways to connect with nature. In collaboration with partners across Australia, the UK, and the US, the team explored the types of GSPs available, who they serve, and their accessibility, acceptability, and affordability for those who could benefit most. Bringing together expertise from environmental epidemiology, psychology, public health, clinical care, and landscape architecture, the project worked closely with government, health, and community organisations to build an evidence base and develop practical guidance to scale up inclusive, nature-based solutions advancing health equity and environmental sustainability.
