We assembled information on the contribution and value of forests to w
orld food security. An assessment was made of the role of forests and
non-timber products in the food system of developing countries. We est
imated that upwards of 300 million people annually earn part or all of
their livelihood and food from forests. A total of about $90 billion
in non-timber products are harvested each year. Forests also help to p
rotect land water and biological resources, and they play an important
role in maintaining the productivity of agricultural and environmenta
l systems.
