FAO today released findings of their global remote sensing survey. This is the first comprehensive picture of losses and gains of forests worldwide.
The results largely confirm earlier numbers by the FAO Global Forest Resources Assessment 2010, which is based on country reporting, however some obaervations can be made:
Tropical deforestation was lower than previously reported, averaging about 9 millon ha/year for the 1990-2005 period. The net loss in the tropics was about 7 million ha/year.
Boreal, temperate and subtropical zones all show net gains of forest area, only the tropical zone has a net loss.
The results will lead to new analyses of forest and land use dynamics, and the approach used offer interesting possibilities for monitoring in REDD+ countries.
