Forests, trees and green spaces, hereinafter ‘forests and trees’ for short, provide multiple goods and services that contribute to human health. These include medicines, nutritious foods and other non-wood forest products (NWFPs). Globally, at least 3.5 billion people use NWFPs, including medicinal plants, which are particularly important for vulnerable groups and Indigenous Peoples and local communities (IPLCs). During periods of crises, such as the COVID-19 pandemic, demand for forest products typically increases amongst these groups. Forests and trees also contribute to better health by playing a role in climate change mitigation and adaptation, contributing to regulating the carbon cycle, but also moderating the micro-climate, filtering pollutants from the air and protecting settlements against the effects of extreme events such as droughts and flash floods.
