Las Vegas is a fantastical Disneyland for adults in the middle of the desert. It features fabulous displays of water — like the thousand dancing fountains of the Bellagio Hotel or the winding canals that recreate Venice at the Venetian Hotel. But surprisingly, it’s a city that has also become known for water conservation and innovation.

In this episode, we sit down with Pat Mulroy, who was the top water manager in Southern Nevada for 25 years and led conservation efforts in the desert city. We talk with her about the existential crisis that Las Vegas and other desert cities face, how Southern Nevada has been able to cut its Colorado River water use by 31% in the past two decades, and what that means for the trade-offs that we all may have to consider to keep living where we want to live.

When Leigh Harris and her husband, Franck Avril, moved into their dream home, Leigh said she felt like the luckiest person in the world. The home is in Rio Verde Foothills, Arizona, outside Scottsdale, in unincorporated Maricopa County. It’s a large stucco house, with high ceilings, a fireplace and 35 windows to take in the mountain views.

There was just one downside. Their home was built on a dry lot, which meant water was hauled in by trucks from Scottsdale. And amid a worsening drought, Scottsdale had to cut them off. This episode, we follow Leigh and Franck as they scramble to find an affordable water supply and make the most of every last drop.

Kingman, Arizona, a small farming town in the desert, is a cautionary tale in the West’s water crisis.

About a decade ago, large corporate farms started moving into the desert of Mohave County, growing thirsty crops like alfalfa and nuts. At the time, there were practically no rules restricting groundwater pumping, and local officials worried the farms would run the town dry. So local leaders did something that hadn’t been done in 40 years. They asked the state to step in and pass strict rules on groundwater pumping.

This episode, we travel to Kingman to look at a complicated solution that has splintered a community, pitting neighbors against each other and farmers and ranchers against elected officials.

The city of Albuquerque exists in part because of the Azotea Tunnel, a massive infrastructure project that effectively rerouted part of the Colorado River into the Rio Grande. The project helped sustain Albuquerque’s rapid population growth. Meanwhile, some communities lost out. Water that would have flowed through the Jicarilla Apache Nation was instead diverted via the tunnel.

In this episode, we travel 180 miles north of Albuquerque to the town of Dulce to talk to Daryl Vigil, retired longtime water administrator, about how the tribe is fighting for a seat at the table in ongoing Colorado River management. And we visit To’Hajiilee, a community dealing with water insecurity that stands to benefit from leasing Jicarilla settlement water.

Over a century after its namesake river — the Gila — was stolen by colonization, the Gila River Indian Community won its water rights back. Now the community is using the water to restore its farming economy, build back wetlands that long ago dried up and help stabilize the Colorado River system.

Buckeye, Arizona, is a small city with dreams of becoming “the next Phoenix.” It’s one of the fastest-growing cities in the country. In the past few decades, its population has ballooned more than twentyfold, and the city plans to add more than 100,000 new homes in coming years.

The only catch? Growth requires water. And Buckeye doesn’t have enough. So what’s a small city with big dreams to do? Part of the answer lies in one scrubby acre of land way out in the desert that’s owned by a group of investors.

The Colorado River is the lifeblood of the American West. Millions of people rely on it to live. But we’re using more water than the river has to give, and it’s already lost trillions of gallons to rising temperatures since 2000. Meanwhile, rampant growth and water-intensive farming have depleted groundwater supplies. This means Western states must fundamentally rethink how water is divided up and used. In this season of “How We Survive,” we find an oasis in the desert, float down Las Vegas’ finest canal and give wastewater a taste as we continue our hunt for solutions to the climate crisis.

When it comes to solving the climate crisis, artificial intelligence can be a powerful tool, but it comes with some significant risks. Marketplace’s AI reporter Matt Levin talks with Priya Donti, Assistant Professor at MIT and co-founder Climate Change AI about the promises and perils of AI.

Do my food choices really matter? What about solutions like composting? In this installment of Burning Questions, NYT’s food journalist and best-selling cookbook author Priya Krishna is in conversation with restaurateur and founder of Zero Foodprint, Anthony Myint, to chat through the personal and structural changes we can make to our food choices to better the climate.

Some climate activists think it’s time to ramp up their efforts by vandalizing multimillion-dollar artworks and even sabotaging key infrastructure.  Should activists move beyond peaceful protests? Host Amy Scott talks with filmmakers Daniel Goldhaber and Ariela Barer about some of these ideas that show up in their environmental thriller “How to Blow Up a Pipeline.”
