Hmmm, don't agree. Precision may be a challenge but that doesn't make attempts to define boudaries meaningless. Political boundaries? Not stable at all. Geography is best, allowing for plate shifts of course.

I think precision is more than a challenge. Precisely defining diffuse boundaries is surely an exercise in spurious accuracy rather than precision? The interface of the Maghreb with the Sahara with the Sahel is not like, say, the straights between Bali and Lombok, where these zoo-geographical boundaries are precise and have some real meaning.
