I don't think forbidding the sale of water internationally would be a good idea.

Many places like Hong Kong heavily depend on imports of water.

They could build desalination plants but those are often very polluting as they don't have space for more passive solar powered desalination systems.

But farmers in California for example pay only 70$ for an acre-foot of water. An acre-foot is 1233m³ and is enough for about 10 families for a year (that pay on average 70$ per month).

So farmers are paying less than 1% of the price of the water.

Maybe bringing that up to 100% would be too large of a shock and put all farmers out of business but it's clear they will have to pay a larger share in the future.

Perhaps they can make exceptions for locally consumed foods to incentivize that. But that is a bit hard to track and verify. And I think more expensive food would most likely be consumed locally anyway.

Not forbid, just heavily regulate. Make sure you settle all domestic uses for water first and then sell abroad. But only to the point where it can be easily replenished in a short amount of time.

Right now we need to focus on our own needs and replenishing our reservoirs more than anything, otherwise ‘nobody’ is getting water.
