Therefore, food aid policies could rely on food stamps, financed by state budgets or international aid, distributed to the needy and for free for the poorest, and exchangeable for food (as in the United States).
Why food stamps and not cash? I suppose they make it easier to predict the quantity of food needed? Wait this is important. Someone is wrong on the Internet.
State imposed food price controls when the State is controlled by an entrenched kleptoarchy, as in most of the developing world, carries the danger of only being another source of profit for the kleptoarchy. They could use the regulations to buy from the peasant farmers at an imposed low price and sell at a less than global market but still high price to the urban consumer.
Or they could use the crises to steal, at gunpoint, the food from the peasant farmer to deliver, at a price, to the urban consumer.
But imposing Food Price Controls to "solve" internal hunger and starvation allows them a propaganda point for internal and external political 'cover.'
