End of Deforestation in View?

An increasing number of countries and regions are transitioning from deforestation to afforestation, raising hopes for a turning point for the world as a whole, according to researchers advancing a more sophisticated approach to measuring forest cover.

Among the 50 nations studied, forest area in percentage terms shrank fastest from 1990 to 2005 in Nigeria and the Philippines, and expanded fastest in Viet Nam, Spain and China.

Growing stock fell fastest in Indonesia, Nigeria and the Philippines, and increased fastest in the Ukraine and Spain.

In absolute terms, Indonesia and Brazil experienced the greatest losses of both forested square kilometers and cubic meters of growing stock; China and the USA achieved the greatest gains.
