The rich countries are also going to be outbidding each other though. Some nations may decide not to sell it all because they need to eat themselves. This would be worse due to limited supply and no way to quickly ramp up.

Countries like the US and Canada, who are net food exporters, would basically be fine. China would face huge problems. Failed states would experience catastrophic famine.

I agree rich countries could buy food up to a point, but if the us and canada had drastically lower yields for a few years, there would be world wide shortages, countries would limit exports eventually.

I asked the question about what would northern countries do because the volcanic eruption impacts seemed to be more focused on the north in the article. But of course the world is connected, and the south is relatively poorer, and we are all connected, and there's not that much excess food. When a huge eruption does occur, or other destructive things like a CME, it will affect the world.

They are currently net food exporters, but with catastrophic harvest failures that would probably change. I'm not sure if anyone has run a detailed analysis taking all the factors in to account, but I wouldn't be so quick to assume they would "be fine".
