Worsening droughts and water shortages

concomitant with record flooding
 

I continue to update my Excel sheet tracking and depicting monthly and yearly Lake Mead water levels. We lived in Las Vegas from 1992 through 2013. Loved it there. But, I would often joke that Vegas was "the next Anasazi ruin."
 

Ran across a cool interview article the other day.
As Colorado River Dries, the US Teeters on the Brink of Larger Water Crisis
The megadrought gripping the western states is only part of the problem. Alternative sources of water are also imperiled, and the nation’s food along with it.

The western United States is, famously, in the grips of its worst megadrought in a millennium. The Colorado River, which supplies water to more than 40 million Americans and supports food production for the rest of the country, is in imminent peril. The levels in the nation’s largest freshwater reservoir, Lake Mead, behind the Hoover Dam and a fulcrum of the Colorado River basin, have dropped to around 25% of capacity. The Bureau of Reclamation, which governs lakes Mead and Powell and water distribution for the southern end of the river, has issued an ultimatum: The seven states that draw from the Colorado must find ways to cut their consumption — by as much as 40% — or the federal government will do it for them. Last week those states failed to agree on new conservation measures by deadline. Meanwhile, next door, California, which draws from the Colorado, faces its own additional crises, with snowpack and water levels in both its reservoirs and aquifers all experiencing a steady, historic and climate-driven decline. It’s a national emergency, but not a surprise, as scientists and leaders have been warning for a generation that warming plus overuse of water in a fast-growing West would lead those states to run out.

I recently sat down with Jay Famiglietti, the executive director of the Global Institute for Water Security at the University of Saskatchewan, to talk about what comes next and what the public still doesn’t understand about water scarcity in the United States. Before moving to Canada, Famiglietti was a lead researcher at NASA’s water science program at the Jet Propulsion Laboratory in Pasadena, California, and a member of the faculty at the University of California, Irvine. He pioneered the use of the Gravity Recovery and Climate Experiment satellites to peer into the earth’s mass and measure changes in its underground water supplies. The Colorado River crisis is urgent, Famiglietti said, but the hidden, underground water crisis is even worse. We talked about what U.S. leaders either won’t acknowledge or don’t understand and about how bad things are about to get.

Our conversation has been edited for length and clarity.

Let’s start with the Colorado River because it’s in the news. The federal government has put some extraordinary numbers out there, suggesting water users cut between 2 and 4 million acre-feet of water usage starting this year — roughly 40% of the entire river’s recent flow. How could that possibly happen?

It’s going to be really hard. We’re looking at drastically reduced food production and the migration of agriculture to other parts of the country and real limits on growth, especially in desert cities like Phoenix. My fear is that groundwater will, as usual, be left out of the discussion — groundwater is mostly unprotected, and it’s going to be a real shit show.

Remind us how that happens. States and farmers cut back on the Colorado River, and California and Arizona just start pumping all the water out of their aquifers?

Yeah. This started with the drought contingency plan [the 2018 legal agreement among the states on the Colorado River]. Arizona had to cut nearly 20% of its Colorado River water. To placate the farmers, the deal was that they would have free access to the groundwater. In fact, something like $20 million was allocated to help them dig more wells. So, it was just a direct transfer from surface water to groundwater. Right away, you could see that the groundwater depletion was accelerating. With this latest round, I’m afraid we’re just going to see more of that.

Some of that groundwater actually gets used to grow feed for cattle in the Middle East or China, right? There’s Saudi-owned agriculture firms planting alfalfa, which uses more water than just about anything, and it’s not for American food supply. Do I have that right?


There’s been other buyers from other countries coming in, buying up that land, land grabbing and grabbing the water rights. That’s happening in Arizona.

What about in California? Groundwater depletion has caused the earth to sink in on itself. Parts of the Central Valley are 28 feet lower today than they were a century ago.

California passed the Sustainable Groundwater Management Act in 2014, which mandated an extraordinarily long time horizon: two years to form the Groundwater Sustainability Agencies and then five years for each GSA to come up with its sustainability plan. So that’s now: 2022. And then 20 years to come into sustainability. My fear is that the slow implementation will allow for too much groundwater depletion to happen. It’s sort of the same old, same old.

But could it work?


I don’t think we’re talking about sustainability. I think we’re talking about managed depletion. Because it’s impossible to keep growing the food that we grow in California. It’s agriculture that uses most of the groundwater. The math just isn’t there to have sustainable groundwater management. If you think of sustainability as input equals output — don’t withdraw more than is being replenished on an annual basis — that’s impossible in most of California.

Will we run out of water? Are we talking about 10 years or 100 years?

Yes. We are on target to. Parts of the Central Valley have already run out of water. Before SGMA, there were places in the southern part of the valley where I would say within 40 to 50 years we would run out or the water is so saline or so deep that it’s just too expensive to extract. SGMA may slow that down — or it may not. I don’t think the outlook is really good. Our own research is showing that groundwater depletion there has accelerated in the last three years.

Then what happens? What does California or Arizona look like after that?

It looks pretty dry. Even among water users, there’s an element that doesn’t understand that this is going to be the end for a lot of farming. Farmers are trying to be really efficient but also magically want the supply of water to be sustained.

We focus on the big cities like Phoenix and Las Vegas, but it’s farms that use 80% of water. They grow crops that provide huge amounts of the winter fruits and vegetables and nuts for the entire country. Is there any way that farming in California and Arizona can continue even remotely close to how it is today?

I don’t think so. It has to drastically change. We’ll need wholesale conversion to efficient irrigation and different pricing structures so that water is better valued. We’ll need different crops that are bred to be more drought tolerant and more saline-water tolerant. And we’ll probably have a lot less production.

What does that mean for the country’s food supply?

This is the big question. I don’t want to be flippant, but people don’t understand the food-water nexus. Do we try to bring more water to the southern high plains, to Arizona, to California, because if the food system’s optimized, maybe that’s the cheapest thing to do? Or does agriculture move to where the water is? Does it migrate north and east? It’s not just food production. What about the workers? Transportation? If we were to move all of our agriculture to northern California, into Idaho, into North Dakota over the next decade, that’s a major upheaval for millions and millions of people who work in the ag industry...
Read all of it. Bracing.

AND, THE HEAT
 

One news item had 127F in Death Valley this weekend.

Uhhh... lest I forget: Flooding, anyone?
 
As I write, 1/3rd of Pakistan is under water, with more than 1,000 dead  The entire population of Jackson MS is without safe municipal water—because of record flooding that destroyed the water management infrastructure.
 
AND, RIVERS GOING DRY
 
Europe’s mighty rivers are drying up in the climate-driven drought

Europe’s major rivers are shrinking under the most severe climate-driven drought in decades.

It’s distressing enough to see mighty waterways like the Loire, Po and Rhine reduced to a trickle in places.  But the ongoing drought is also revealing how much we depend on them for trade, energy and transport.

The Rhine’s evaporation is especially concerning. At the chokepoint of Kaub, near Frankfurt, it is expected to fall below 40cm on Friday. This would make it impassable for some larger ships carrying supplies of oil, coal and gas...
We're seeing similar problems in Asia.
 
SEA LEVEL RISE?
 
 
"Zombie Ice?"

Lots of bad stuff looming.

 
Again, these travails can be multidimensionally adverse-feedback-loop reinforcing.

UPCOMING BOOK RELEASES
 

Award-winning YALE PROFESSOR Woo-kyoung Ahn delivers “A MUST-READ—a smart and compellingly readable guide to cutting-edge research into how people think.” (Paul Bloom)

 
Psychologist Woo-kyoung Ahn devised a course at Yale called “Thinking” to help students examine the biases that cause so many problems in their daily lives. It quickly became one of the university’s most popular courses. In Ahn’s class, students examine “thinking problems”—like confirmation bias, causal attribution, and delayed gratification—and how they contribute to our most pressing societal issues and inequities. Now, for the first time, Ahn presents key insights from her years of teaching and research in a book for everyone.



Ahn draws on decades of research from other cognitive psychologists, as well as from her own groundbreaking studies. And she presents it all in a compellingly readable style that uses fun examples from K-pop dancing, anecdotes from her own life, and illuminating stories from history and the headlines.


 
Thinking 101 is a book that goes far beyond other books on thinking, showing how we can improve not just our own daily lives and tackle real-world problems through better awareness of our biases but also the lives of everyone around us. It is, quite simply, required reading for everyone who wants to think—and live—better.

The tech elite have a plan to survive the apocalypse: they want to leave us all behind.

Five mysterious billionaires summoned Douglas Rushkoff to a desert resort for a private talk. The topic? How to survive The Event: the societal catastrophe they know is coming. Rushkoff came to understand that these men were under the influence of The Mindset, a Silicon Valley–style certainty that they can break the laws of physics, economics, and morality to escape a disaster of their own making—as long as they have enough money and the right technology. In Survival of the Richest, Rushkoff traces the origins of The Mindset in science and technology through its current expression in missions to Mars, island bunkers, and the Metaverse. This mind-blowing work of social analysis shows us how to transcend the landscape The Mindset created—a world alive with algorithms and intelligences actively rewarding our most selfish tendencies—and rediscover community, mutual aid, and human interdependency. Instead of changing the people, he argues, we can change the program.
I saw and read reviews on these soon-to-be-released titles today in Science.

I've previously cited Douglas Rushkoff's prior book "Throwing Rocks at the Google Bus" some years back. Adroit writer.
