how does waste prevent a shortage from becoming a famine ?
Making the expected production a higher number than the expected need will give the headroom necessary to deal with a shortage without people starving.
If you’re aiming to produce food for a population of 100,000, but have the capacity to make food for 200,000, then you can afford to waste half of your food without starvation. You can also accommodate a 50% drop in production without starvation.
So that buffer is expected waste, but it’s also starvation resistance.
