I don't recall reading something like that in the Volume 7 intermission. The conversation between PDL and Rigrit never mention such a thing other than the hint about conflict between wild magic and yddrasil  type magic. As for the beastman nation, it is likely that something or someone is instigating them to create people farm. The concept of farming for food maybe quite new for the beastman. Hence, it can be speculated someone is teaching them this concept. If someone is teaching them, who could it be doing that? They maybe several suspects.

1) Demiurge - He has operations around Holy Kingdom which is near the Dragonic Kingdom. Could he be using the farms for his breeding experiments? He can masked the actual the presents of his breeding experiments by making it look like a large scale food farm.

2) Unknown party - possibly additional Yddrasil players transported same time as Nazarick? They maybe demi-humans being transported to the beastman nation.
