Tree cover far bigger than expected on farms: study | Green Business | Reuters

OSLO (Reuters) - Almost half of the world's farmland has at least 10 percent tree cover, according to a study on Monday indicating that farmers are far less destructive to carbon-storing forests than previously believed.

"The area revealed in this study is twice the size of the Amazon, and shows that farmers are protecting and planting trees spontaneously," Dennis Garrity, Director General of the World Agroforestry Center in Nairobi, said in a statement.
