My understanding is that desalinization should be a method of last resort, since it produces a lot of brine that is hard to deal with at scale in a way that isnt bad for the marine life. Depending on the desert, dew collectors might work, although I havent looked into how much water sphagnum moss needs over a year, now much a dew collector can produce, how much evaporation would happen, etc.
