A Vancouver family physician has launched the International Nature Prescribing Alliance to help medical professionals worldwide adopt nature-based health interventions. Announced at the COP17 biodiversity summit in Armenia, the initiative connects healthcare providers through a global digital hub so more patients can be guided toward time outdoors.
How do nature prescriptions work?
Nature prescriptions encourage patients to improve their physical and mental well-being by spending time outside. Doctors at PaRx say that as little as two hours a week outdoors is linked to documented health gains. In practice, clinicians can issue formal prescriptions that give patients concrete opportunities, such as:

- Free or reduced-cost park passes
- Tickets to nature-themed art exhibits
- Access to other nature-related community offers
Why is this expanding internationally?
The movement builds on a Canadian foundation known as the PaRx program. This national model, endorsed by the Canadian Medical Association, has already gained participation from more than 22,000 healthcare providers. According to Dr. Melissa Lem, the founder of the new alliance, international interest surged after Canada began collaborating with organizations like Parks Canada to reduce barriers to nature access. Lem said countries repeatedly asked for a version of what Canada has built.
What is the goal of the alliance?
The alliance functions as an online hub featuring an interactive map of existing nature prescription initiatives worldwide. This tool lets healthcare providers see how different regions run their programs and connect with global counterparts to share expertise. While the United States and Canada already have established programs, the alliance aims to help other regions adapt proven methods to their local ecosystems and public health needs. Italy recently adopted a similar approach.
