"The food-versus-fuel debate is
about whether the use of agricultural output for energy purposes competes with its use for food purposes either directly (where the same crop could be used for either food or fuel) or indirectly (where land use for energy crops displaces food crops) and leads to food shortages and/or higher food prices as a result. The debate has been around for a long time, but it was the steep rise in global food prices that started in 2006 that has catapulted the debate to global prominence."

Whatever the discussion, Industries for Africa Foundation has the perfect solution - using non-arable drylands for the growth of jatropha ( a poison plant that happen to like drylands) to produce biodiesel and hereby create arable land around the plantations for foodcrops.
I think the discussions are barking on the wrong tree, mostly cause people are not checking the facts proberly before stating an opinion.
Please correct me if I am wrong - or discuss the topic with me!
