I haven't seen many food problems in my realms, but they are a very small sample of the game's realms. I still think one of the easiest solutions would be to implement partial order fillings for purchasing/selling along with auto-offers.
From what I see in my Dwilight realm, it's more about finding where the large surplus is and then shuffling it into a central area for sales. My lord on the outskirts of the Farronite Republic is now seeing little offers being taken up at only 10 gold per 100 bushels, and gradually building a stockpile from neighboring realms and even a neighboring region of my realm. It is kind of weird, since the margrave of the capital complains about often paying more than 50g/100b....I pay 10/100 without even having to write a word. Maybe people just want to keep Hvrek passive.
