Habitat for the addax antelope, which can go a year without drinking

I believe the answer is:

sahara

(Other definitions for sahara that I've seen before include "About 3,500,000 square miles of Africa" , "Great desert in N Africa" , "Hottest desert" , "Uncultivated region of north Africa" , "Great African desert" .)

I've seen this clue in The New York Times.
