I'm not sure what you mean by "there" because metropolitan areas typically do not have much agrarian enterprise, but Arizona grows plenty of cotton, beef, and citrus, and always has.

Of course, the urban landscape as it is now, used to be dominated by farmland, and so it isn't what it used to, but if you meant to write "they can't grow food there" that also another lie, because there is plenty of food that grows quite well here. In fact, several of my friends love to share the produce from the trees in their yards and their backyard gardens.
