This is harder to organize than other things. this is not money so we need to actually generate it. if we were to observe the homelands, we will find that everyone here has food except for those without land. the cheapest but slowest solution to this is to take the rubbish from the food stuffs of those with land and give it to the people that have no food as compost or whatever you call it.
Or, we could take the excess from the established commercial farms and give to them before it spoils. this will take very little effort. we could make this more formal with paperwork or something, like an election where the people get their thumbs inked? the state could buy a lot of food with a inkling of the revenue.
