> For California, drought/water shortage is primarily and agricultural problem, but has been externalized to urban areas and consumers - urban uses are 10%, while 40% goes to agricultural uses.
Yes, agricultural dominates usage, but southern california with no agriculture would still have to transfer water from elsewhere (colorado river, sacramento delta etc) in order to sustain the population.
This source from LATimes in 2019 seems to think it’s doable (not cheap) and doesn’t event include desalination, just recycling and capturing rainwater: https://archive.ph/l0To2
Personally, I’d want desalination in the mix for resiliency/diversification.
