I have yet to hear about the possibility of printing ration books, but would not surprise me if that process has already been completed - Ian, having been in a similar position as you some time ago, and have had some experience how the military and gov work, everything as you are no doubt aware is 'compartmented' - the idea being that no one section really knows what the other section is doing..LOL typical political speak etc..this basically cuts down to a 'need to know' basis
However, I do know that here in Wales for example, due to the poor weather conditions, many spud harvests have been affected by blight, and the grain has resulted in browny harvests rather than golden yellow - the result being farmers will have to buy in grain for animal feed, and because they have to buy in from USA who have suffered major droughts, the feed is expensive and soon prices will be doubled - result... higher prices and shortages - many farmers may go bankrupt and supplies of meat products will be in lean supply.
Here is today's news from BBC wales on this very subject..

The situation will worsen at a rapid rate...
