Remote sensing and measuring deforestation

Forests occupy one-third of the planet's landmass, covering nearly 4 billion hectares. The largest forested areas are located in the boreal and equatorial zones. This current distribution is not fixed, but has continuously changed over time due to the influence of environmental change and anthropogenic impact. One-third of current forested areas are made up of forest that is considered primary or intact. The remaining two-thirds are subject to anthropogenic activity and have, as a result, an uncertain future. (Résumé d'auteur
