Maybe this is a little late, but isn't the idea of food rations for peasants a bit strange? They aren't soldiers you distribute food to. They farm all of the food, and some of it (the surplus) is taken as taxes for the lord. If surplus is is lower than 0, the region starves.
In order to make a region last longer on food, instead of handing out rations, doesn't it make more sense to lower surplus extraction? I wouldn't propose calling them taxes though, as that can only cause confusion.
