Depending on the state, actually, you might be able to do something like that. One of the requirements for adverse possession is that the use is hostile--not by consent of the person who holds the title to the land. If you own land (or an appurtenant right to land, like an easement or a water right (though water law is a whole other ball of wax, especially in the West)), you can often stop an adverse possession claim from arising by merely drafting a "license" that allows the person to use the land, but states clearly that you can revoke the license anytime you want. Sign it, and get the person using the land to sign it, and you should be good to go. No "hostile" use = no adverse possession. FWIW, when the LDS Church was suing the RLDS Church over the Kirtland temple some years ago, I'm told the court dodged the issue of having to choose the "real" successor to Joseph Smith by simply giving the temple to the RLDS on a claim of adverse possession.
