I'm thinking wildly here and not getting into technicals, but it could also be seen not necessarily for humans but also for ecosystem restoration efforts in harsh remote environments.

For example, while I have some viability questions the company Terraformation has been trial'ing photovoltaic solar powered water desalinization (using brackish wells as a source) in deforested areas for water - https://www.terraformation.com/blog/solar-powered-desalinati...

If I understand correctly (still learning and might be wrong), another way to frame this is in perceiving water vapor itself - you can be in desertifying areas and yet supposedly have plenty of water vapor to a lack of evapotranspiration. This is what some have framed 'the second leg of anthropogenic climate change' - ( https://museecology.com/2020/10/30/15-professor-millan-the-s... , https://www.youtube.com/watch?v=mf4jwkhCk_A - "Desert or rainforest" , https://www.youtube.com/watch?v=UdcsQw3ma_Y - "Restoring the Water Cycle 1" )
