World forest cover declined by some 5.3 million hectares a year between 1990-2010, said FAO while releasing data on forest resources on the occasion of International Day of Forests.
As of 2010, the total forest cover was 3.89 billion hectares, or 30 percent of the land area, according to the updated findings of a global remote sensing survey.
The area of tropical forests declined in South America, Africa and Asia - with the biggest loss in absolute terms in tropical South America, followed by tropical Africa.
