Your buffer here is meat. Cattle are tremendously inefficient consumers of grain. Eat your burgers in the bountiful years, then slaughter 75% of the herd in a hardship year, eat well for six months, then spend the next three, four, five years eating more grains while the herds recover.
Ethanol is another one.
That's the sensible way to do it.
Somehow I doubt that it's the way we do it... But maybe the variability is coming from world trade and developing nations.
Cattle are inefficient consumers of grain, but highly efficient consumers of grass. Most land used for pasture can't effectively be used for anything else.
This argument might sound good, but those cattle are fed crops, not just sunshine and the grass they walk on.
Most crops grown in the US are used as animal feed. They are dependent on arable land that could be used to grow food for humans directly and much more efficiently. We just like the taste, so we accept the inefficiency.
Eh. The "inefficent calorie conversion" take is sort of lazy and misses the nuances. I just looked it uo, and it seems that only about 55% of yields are for feed, and there is definitely some more nuance there, since a lot of feed meal comes from stalks and parts if the plants humans would not consume. This notion of calorie inefficiency also misses the mark on what would be planted and harvested instead to contain the same bioavailable nutrient profile thay comes from meat. In otber words, using land for feed to convert grains to another type of food is probably more necessary than just "taste".
I don't care to research it further, but I own a small 5 acre farm and can attest that some crops grow in some areas and some don't. So even if you did map it all out on a piece of paper where you'd get all your beans and lentils and whatnots I doubt it would work in real life. Cattle can handle a couple hard freezes. My tomatoes can't.

We feed the average cow >10lbs of grain and also some alfalfa for every pound of meat we get out right now.
Part of the cull would likely be shifting towards more grass fed production. Another part would simply be prioritizing chicken or pork for a while.
Americans would riot without burgers.
