I have some food stored away, enough for a few months that I rotate out as it ages. But it's for emergencies, not EOTWAWKI.

Thing is, staples are still so cheap, relatively speaking, and food so currently plentiful, that I find this very difficult to believe.

What may happen, is a Camp of Saints like famine in very marginal regions, because existing and future supply will be allocated, via the market, to places that can afford to pay more, which is the developed world.
