I would like to insert that large scale agriculture may not be the short term solution to the problems. For example, it has been said that Uganda currently produces enough food to feed itself however it has energy problems (read that fuel) in transporting it from where it is grown to where it is needed. With that in mind, perhaps (certainly for the short term) a solution is much more sufficiency agriculture that requires no transport. Large scale agriculture often involves mono-cropping which in itself is economically risky for poor people. It also means that I might grown cassava but not any of the other food required to live. That then makes me dependent on a cash economy to fulfill daily requirements. If nature or politics destroys my ability to produce and distribute my mono-crop, I am in serious trouble. Most famines in the world today have nothing to do with lack of food but rather distribution.
