Pumping the desert wetlands.
A far easier way is to simply pump seawater up to hill tops opened up with retention ponds. These ponds are then used to feed terraced wetlands cascading down hill. all this can be planted with useful salt resistant cultivar's.
All this humidifies the former desert air which then runs a full on hydraulic cycle as the ground is covered with trees and other vegetation.
The fresh water circulation soon clears away the salinity. I think we will be shocked at how fast this can progress once we get over ourselves. suddenly the Sahara et al become the Amazon with a an inch of rain every day.
The central fact we forget, is that a tree sucks up seventy liters of water and dumps it into the atmosphere which moves it along before dumping it back a few short hours later. All driven by the sun
All this begs the big question. Just how are we going to lift all that sea water. I do think tgat our best strategy is to run channels inland all along the coast so that you can have a tidal drive to fill the storage pond and then have the water lifted to a next hydraulic stage retention pond. this can operate 24/7 using a local power solution. Additional lifts can also be installed to gain greater elevation. The fact is that we do not have to lift all the system water to the highest point. We need just enough to ensure wetlands for every contour.
What this does do is provide a base load for the grid that is large enough and flexible enough to handle large populations.
in fact, once built, the actual induced rainwater may well fill the whole system and obviously transition to a freshwater system.
However long we take to build all this, it is plausible the salinity will be washed out inside of a decade upon completion..
We have had our eyes on the lack of water and forget it is lack of trees. any mangrove will do as a starter and a couple of decades later we will grow redwoods.
