For Beluaterra, at least in Fronen, there seems to be a general surplus and we have supplies to last a while. I believe it is due at least in part to which regions were lost permanently. The continent lost a disproportionate number of cities & townslands compared to other regions.
I'm not a trader but there are usually a number of sale offers sitting on the market. Prices seem low (between 20 and 25 gold with some less than that) due to the abundance of food in regions so rural lords have an incentive to reduce prices to try to get cities to buy before it rots.
