I have a strange kind of Deja-vu feeling. I remember answering this question some days ago, but I can't find it. Perhaps I only intended to answer or got interrupted.

Starving numbers is random, but dependent on needed supplies vs total supplies.

Terrain survival: 50% chance of not affected by starvation (IIRC).
