No matter if you’re whipping up a cacciatore, amatriciana or a homemade pizza, you’re going to need one thing: tomatoes.

But while most of the tomatoes consumed in the U.S. — fresh, canned, and otherwise — come from California, factors like the ongoing drought, rising fuel prices, and a changing climate are making the fruit harder and more expensive to grow. And that’s prompting some California farmers to consider raising other, hardier crops that require less irrigation.
