A sub-topic to #16: Food.

What are the commonly grown crops in your world? Tell me all the areas you thought of. Such as, in the north, the south, rural, urban, wetlands, desert, etc.

Who owns the farmland? The farmer? The lord? Government? King?

Do characters in your world keep livestock? If so, what do they keep? (This, I'm especially interested in for those of you who have a world consisted of only non-human characters.)

Are crops and livestock grown only for personal consumption or do they sell these at markets as well? How is the food transported?
