Production of food is not the problem. The problem is getting it to where it's needed. Often the worst famines have nothing to do with not enough but with inadequate distribution, often due to war. Many times food that is delivered by charities is taken over by warlords who then profit on it.
Yeah, but there is something to be said for sending food when there is a drought or some other disaster that has caused an actual shortage of food.
Some of the food that we send will end up in the hands of the people after the government officials have stolen their share of the food and the local warlord has taken his toll and what not.
