In the world
Peatlands cover some 423 million hectares of the Earth, which represents 2.8% of the total land surface area (Xu et al., 2017). Peatlands are more widespread in Asia (38% of peatlands) and in North America (32%) followed by Europe (12%) and South America (11%).
Canada contains 27% of the world’s peatlands and is the second country with the most peatlands after Russia.
