I gotta imagine making the Sahara Desert habitable is a lot easier than making Mars habitable. The Sahara at least has breathable atmosphere, a 24 hour day, solar intensity that our plants are well adapted to using, and is relatively close to resupply from population centers on Earth.

And Sahara was a jungle pretty recently.
