Maybe we need to look at cloud-seeding or other rainmaking solutions like the UAE is doing

Sure, let's ignore the simple solution - stop consuming so much water - and jump to a high-tech, unknown impact, expensive, complex, expensive solution. What could go wrong?

The thing is, "stop consuming so much water" not the simple solution.

Chinese and other overseas investors own those US desert farms. They were attracted here by the massively generous water rights they get automagically. ref: https://grist.org/agriculture/u-s-southwest-already-parched-...

Damn I want a dessert farm

It works, but it requires tons of precious metals to get to work and we could never recover the amount of water or even the metals themselves to make it efficient. Do-able, just going to cost money like no tomorrow. Literally the definition of throwing money at the problem. When you have a uber rich oil state with plenty of cash to burn, it'll work until they run out of cash or desire.

I just read an article (maybe on HN) that they are doing so with drones that shoot electricity or something like that

No heavy metals or consumable materials needed?

seems like desalination parried with nuclear and solar power (because desalination is expensive electricity wise) is the solution. most of our problems comes down to energy, to which fusion power will one day solve. we just need some stop gaps.

Why would we desalinate water when there is water already desalinated by nature available for us? Like I mentioned earlier, I'm not against desalination, it just seems crazy to leverage it to supply all of our water shortfall. Wouldn't a network of canals and pipelines allow the country to be more secure and handle disasters more effectively?

You would still need a network of canals and pipelines, because places like Colorado and Utah facing imminent water shortages aren't close to the ocean.

Desalinating plus pumping water up to those places would be insanely expensive though. It's not economically feasible for the primary uses of fresh water (farming).

Does anyone have educated views on desalinization tech? That seems to be the few ways out of this that's totally within our control. I imagine we'll rob Peter to pay Paul with it via extincting a bunch fish we didn't mean to in desal turbines or something unexpected like that, but that aside..

It works just fine, but it's expensive and requires a lot of power as well as access to an ocean. You can read about the one that San Diego uses for something like 7% of total water needs here: https://www.carlsbaddesal.com/ and here: https://en.wikipedia.org/wiki/Claude_%22Bud%22_Lewis_Carlsba...

Definitely, but highly wasteful nonetheless. Easier to tell someone to stop growing their lawn than telling a farmer to stop growing their crops

Is it? Farming represents 3% of California's GDP, but 40% of the water. If California decided to simply sell that water to other states and then give the money to the farmers in exchange for not farming, the farmers would probably come out ahead. It's also a lot easier to enforce than making sure people don't grow lawns.

> It's also a lot easier to enforce than making sure people don't grow lawns.

It might be easier to convince people to not grow lawns if we'd do away with some of the stupid laws and ordinances that require people to have "well groomed" lawns in places where such grass is an unnatural imported occurrence.

Perhaps even offer some tax breaks or other incentives to "zeroscape" or landscape their yards using native plant life suited to the climate. A yard without a lush verdant lawn need not be an ugly yard. It can still have plants and look nice without grass, if we'd "normalize" more nature/planet friendly practices instead of punishing people for not being destructive to their environment.

I bring this point up because here in Utah many neighborhoods will actually fine you if you don't have a lush green lawn in your yard. (Unless of course you're rich, then somehow you magically get approval to go the zeroscape route if you so desire.)

> 82% of Utah water goes to farmers. Of the remaining 18%, ~ 8% goes to commercial/industrial use ~ 10% goes to municipal residential use (outdoor: 6%, indoor: 4%) [1] [1] https://le.utah.gov/interim/2012/pdf/00002706.pdf

i.e. taking shorter showers ain't gonna cut it

There was also a segment on water usage in Cowspiracy for California I think.

Water usage in industry is massive. Individuals aren't to blame and shouldn't take any part of the burden. Similarily, CO2.

I know this may be silly but one reason why I stay in the "Great lakes states" and own property here is because of global warming and my lack of hope that tech/governments/capitalism will solve it before we reach a point of no return during which we will experience massive property and life loss in the US. Only then significant change will occur IMO. There are places in the south now that need water to be delivered b…

It's not that you aren't correct on some time frame, its more so that you have to live your life there for the entire duration that you aren't correct.

So, whatever helps you sleep at night.

Approximately 27% of the water used in Utah comes from the Colorado River and 60% of Utahans benefit from the river. 82% of Utah water goes to farmers. Significant amounts of that water usage is to grow Cotton and Alfalfa. Two water intensive crops that are largely exported out of the country. In my opinion we have absolutely no business growing these crops in a desert, especially just to ship them out of the country…

Expecting all the modern amenities of life while living in the desert is just pure arrogance. I seriously don't know why governments subsidize it.

People absolutely should live in the desert.

It's better than what we usually do: destroy natural bio-diverse habitats along rivers and coasts and replace them with housing and strip malls.

It's arrogant to expect that water irresponsible states should have any claim whatsoever to the water in states that are responsible with their supply.
