There is the vapour ...

There is the vapour harvesting in Yemen: http://www.undp.org/content/undp/en/home/ourwork/ourstories/harvesting-fog-in-western-yemen.html

There is a French solution of using windmills: https://www.fastcompany.com/1679656/a-wind-turbine-turns-dry-desert-air-into-precious-drinkable-water

There are many other things, I assume. 

I was always wondered that a windmill replacing the compressor motor of a refridgerator/heat pump would create enough cooling for water harvest. The same applies for a big collector lens focused on the heating point of a vapor absorption cooler. Both of these might create something cold in a renewable way, inducing condensation.
