Vancouver physician Dr. Melissa Lem launched the International Nature Prescribing Alliance this week at the COP17 biodiversity summit in Armenia. The collaborative effort aims to share expertise and facilitate nature-based health programs globally.

Why it matters

The move follows international demand to replicate Canada's successful nature prescription model, which connects health outcomes to environmental engagement. By facilitating global connectivity, the alliance seeks to support the health benefits of spending time in nature.

The PaRx program currently includes 22,000 health-care providers who advocate for two hours of weekly nature exposure to improve health. This initiative aligns with the 2030 global target to protect 30 percent of the world's land and water.
