DEFORESTATION: GETTING TO THE ROOT OF THE PROBLEM disappearing at a rate equivalent to 6 DID YOU KNOW? 27 football 昀椀elds per minute with 10 million ha lost in the last ten years. A昀昀orestation is the conversion from other land uses into forest, or the Forest degradation is a related issue increase of the canopy cover of a particular area of land by more than 10%. 9 which plays a signi昀椀cant role in This includes the conversion of land to forest. reducing biodiversity and preventing Reforestation is the re-establishment of forested areas which have recently carbon removal. It is de昀椀ned as a 10 deterioration in the density or structure dropped below 10% tree coverage. of vegetation cover or its species composition. This can be temporary or 7 permanent. Degraded forests do have Scale of the problem tree coverage, but their environmental contribution to biodiversity and carbon Forests cover almost one-third of The good news is that the rate of sinks is reduced. Fires, disease and pest the Earth’s land.
