If he's travelling long distances through arid terrain, yes.

GURPS' default style is "realistic cinematic" - characters need to make sensible plans, use the right equipment and supplies, and consider realistic costs, problems and logistics. As GM, you can ignore some of these issues if you want, which will get you more of a TV show atmosphere. It's a good idea to make those decisions deliberately, and tell your player(s) about them, to avoid clashes of expectations.
