Seventy percent of the world's hungry are rural people dependent on farming. This number rises to 80 percent when including those who herd, fish or rely on forest resources.
"FAO calculates that around half of the world's hungry people are from smallholder farming communities, surviving off marginal lands prone to natural disasters like drought or flood. Another 20 percent belong to landless families dependent on farming and about 10 percent live in communities whose livelihoods depend on herding, fishing or forest resources."
