... that'll be a drop in the bucket. cereal grains alone use more than 10x [1] the amount of land used for vegetables. Add in other large users (coarse grain / oil crops) and it's over 20x, meaning you'd get like a 5% increase by replacing all vegetable land with grains.

thanks for sharing, thats pretty good data.

can't disagree with that. seems like even more reason to not use the land for things that can be grown vertically/hydroponically.

But definitely something i'll be reading more on, thanks for the resource.

It wouldn't be particularly nutritionally useful, and you'd be able to grow grain for a couple of years before your soil turned into dust.

That's why America starved in the 1930s.
