This may seem like an aside, but in the D&D setting Dark Sun, most of the city-states use something called the "ceramic piece" as a basic unit of currency. It, like the Fremen water rings in the Dune series, was a system of currency based on obtaining water from the public water supply. There was never any mention of seed, so one can assume that the Templars were actively banking seed as well as water.

After all, the Sorcerer-Kings needed a ton of life energy so they could undergo the rituals needed to become dragons, and they couldn't drain enough energy from the plants and animals alone. Kinda grisly, but at least they had a bit of forethought.
