Yep. When I go to my neighborhood grocery store in the SF bay area, half of the fruits and vegetables tend to be arriving from Mexico or elsewhere in Latin America or Washington state already. The percentage is even higher in the off-season. Put another way: Where do Maine or Texas or Hawaii get fruits and vegetables that aren't local? (And why are we growing rice in drought conditions?)

Also: desalination puts a floor on the cost of water for drinking purposes. Modern desalination techniques are very electricity-bound, though, in terms of cost.
