It's not news and I'm not alone in warning you to stock up as much as you practically can. The drought is driving up food prices already. I've said it before and I'll say it again. Learn.
This is the year to learn to can and dehydrate. It's time to learn to shop the sales efficiently. Learn to use a price book. Learn to look in other places besides the grocery store for food. Learn to glean; to take advantage of free food; to use that food; to cook from scratch.
Learn where to get farm fresh eggs and how to forage for wild food. Learn to shop at farmer's markets and salvage stores.
When (if) things get back to normal, you'll be far ahead of the game.
Don't just think about it. Do it.
