TUSAQUILLAS, Argentina>> Irene Leonor Flores de Callata, 68, treks along a bone-dry riverbed, guiding a herd of llamas and sheep through stretching desert.

Flores de Callata’s native Kolla people have spent centuries climbing deep into the mountains of northern Argentina in search of a simple substance: fresh drinking water.

Here, in one of the most arid environments in the world, it’s a life force that underpins everything. In rainy months, the sacred lands surrounding their small adobe town of Tusaquillas well with water. In the dry months, families hike miles under the beating sun, hopeful their livestock can sip from a small plastic container, fed by a hose running high into the distant mountains. Today is a lucky day. Their blue container is brimming with fresh water.

But communities such as hers increasingly worry that their luck may run out. That’s because the parched waterways surrounding their town are intrinsically connected with spanning white salt flats below, subterranean lagoons with waters jam-packed with a material that’s come to be known as “white gold” — lithium.

In the “lithium triangle” — a region spanning Argentina, Chile and Bolivia — native communities sit upon a treasure trove of the stuff: an estimated trillion dollars in lithium.

The metal is key in the global fight against climate change, used in electric car batteries, crucial to solar and wind energy and more. But to extract it, mines suck water out of the flats, tethered to the lives of thousands of communities, including Flores de Callata’s.

As the world’s most powerful increasingly look toward the Triangle, the largest reserve of lithium on Earth, as a crucial puzzle piece to save the environment, others worry the search for the mineral will mean sacrificing that very life force that has sustained the region’s native people for centuries.

“We will lose everything,” said Flores de Callata. “What will we do if we don’t have water? If the mines come, we’ll lose our culture. We won’t be left with anything.”

At the same time Flores de Callata’s town and thousands of others across the “lithium triangle” have lived quietly off the sparse food and water their lands offer, the price for lithium skyrocketed in 2022.

From 2021 to 2023, the price for a ton of lithium in U.S. markets nearly tripled, reaching a high of $46,000 last year, according to a United States Geological Survey report. In China, the main customer of the region’s lithium, a ton of the metal went for a whopping $76,000 at its peak last year.

Leaders, mining executives and companies from across the world began to turn their heads. From the U.S. and China, they looked to the region’s barren deserts both as a source of wealth and an engine to power the transition to green energy.

U.S. President Joe Biden has pushed for a shift to more sustainable energy sources, such as wind and solar, and aimed to have half of all new vehicle sales in the U.S. — about 8 million cars a year — be electric by 2030. All require lithium.

In late February, Biden’s top diplomat, Antony Blinken, underscored the importance of Argentina’s lithium in a visit to the South American country.“One of the most important (steps) to our shared future — in fact, one of the most important to the entire planet — is clean energy,” Blinken said. “Argentina is poised to play a critical role in building supply chains for critical minerals that will drive the economy of the 21st century, particularly things like lithium.”

The high demand surged global lithium production, but in recent months prices have dipped significantly because of a short-term oversupply in the metal and overestimates in electric vehicle purchases. Yet global consumption of the lithium continues to rise.

The “white gold” they seek is contained in the hundreds of salt flats, or salares, speckling the region.

From afar, they look like fields of Arctic snow, but below are deep wells of salted groundwater packed with minerals. Unlike other forms of mining, lithium here is extracted not from rock, but rather from the brine water pumped from the salt flats.

The problem is that the salt flats also act as an essential part of a highly biodiverse ecosystem, say scientists such as Ingrid Garcés, a hydrologist from Chile’s University of Antofagasta.

Although the water inside the lagoons is not drinkable, they are tethered to surrounding fresh water sources, sparse rains and nearby mountain streams, essential for the survival of thousands of indigenous communities.

The concern by scientists interviewed by the AP is that industrial-scale water pumping contaminates fresh water with brine they pump and effectively dries up the surrounding environment. They say it has produced cascading ripple effects for life in the region at a time it’s been hit by drought.

“We’re talking about a living ecosystem, because what you’re extracting from this salt flat is water. And water is life,” Garcés said. “Think of it as an interconnected ecosystem.”

Because of their environmental significance, the salt flats and their surrounding waters have gained a sacred place for Indigenous cultures, an essential part of native celebrations the entire month of August.

Flores de Callata’s town is one of 38 pressed up against two such salt flats — the Guayatayoc lagoon and Salinas Grandes — which bring income to towns such as hers through tourism and small-scale salt harvesting.

At the beginning of any day of work, Flores de Callata’s family makes an offering to Pachamama, an Andean deity representing the Earth. Inside their stone corral of llamas and sheep, they dig a hole in the ground, burying coca leaves, meant to represent life, and a clear liquor, representing water.

Just as the basin provided for the Kolla people, fundamental to their culture is giving back to the land. For decades, their collective of communities have fought off large-scale mining and waged long legal battles to halt projects.

But year by year, it’s grown more difficult to fend off those mining companies.

More than 30 companies are officially seeking permission to mine the water in the two salt flats. Signs put up by the community line the edges of the flats reading, “Respect our territory. Get out, lithium company.”

“We are guardians of the highlands,” said Flores de Callata. “We defend our land. … I’m worried not just for myself but for all of us. If the lithium (mines) come, it’s going to affect the entire region, all of the waterways by extension.”

Things came to a head last summer when the local government, eager for the profits by the mines, changed its constitution, making it easier to waive certain indigenous land rights and limiting the ability to protest against the expansion of mining.

Alicia Chalabe, the environmental lawyer representing the communities, and others argue the move violates international law.

Thousands of indigenous people erupted in protest, blocking off roadways used by lithium mines and carrying rainbow indigenous flags. The backlash by authorities toward peaceful protesters was marked by violent repression and arbitrary arrests, according to groups such as Amnesty International and the United Nations. Yet protests are expected to continue.

“This is a domestic conflict that is set in the context of a global issue, where there’s a tremendous pressure to exploit lithium for electric vehicles,” Chalabe said. “It’s global because of the importance lithium has for the world, but at the same time, so is the resistance of these communities. They’re not alone.”

 

Concerns in Chile

 

Argentine concerns are born in neighboring Chile, where lithium mining has been in full force for decades in the Atacama Desert, the driest place on Earth.

Giant black tubes pumping salted groundwater run like veins through the cracked, white earth of the Atacama Salt Flat. They wind past roaring yellow bulldozers and workers in bright orange vests.

The flat is home to the two lithium companies operating in Chile, SQM and American-owned Albemarle.

“We’re living through a crisis in which we have big obstacles, but we also have solutions. Lithium represents one of those solutions,” said Valentín Barrera, a spokesman for Chile’s largest lithium mine, SQM. “We want to grow, understanding that it’s needed to mitigate climate change.”

Here in the SQM mine, that means pumping at least 1,280 liters of salted groundwater a second — somewhere between 6 to 8 bathtubs — according to the mine’s numbers. The tubes converge at rows of blue, green and yellow pools, where lithium-concentrated water is passed from pool to pool.

The harsh desert sun evaporates the water, and strong winds often blow it out of the ecosystem, carried as far as Brazil, one mine official said. Because of the evaporation process and harsh winds, hardly any water can be reinjected into the soil. It leaves behind salt and lithium, to be processed and used by some of the world’s biggest companies, such as Tesla.

Meanwhile, surrounding communities have watched their lands shrivel.

Farmers like 62-year-old Orlando Morales living near the mines complain of smaller crop yields.

Flamingos, feeding on microorganisms within the brine, have slowly been killed off by mining, a 2022 study showed. Their eggs were once a crucial part of the local diet, and the birds continue to be a big part of indigenous celebrations.

Meanwhile, wells and lagoons next to the mines brimming with intense blue fresh water dried up. The grass Morales’ livestock would once eat has vanished, he said.

“Before, it rained more here, and today it practically doesn’t rain. If you look out, it’s all dry. So it’s hard to care for your sheep, your llamas because there’s no vegetation,” Morales said as his wife tended to a patch of corn. “Our people are losing our traditions, our customs are being lost.”

Like in Argentina, the mining spurred on waves of criticisms and court battles as locals demand to have a voice on the fate of their lands.

In 2013, an environmental inspection found that a third of the carob trees — a plant known to survive in harsh environments — near the SQM mine had died. Many more trees were withering.

An investigation in 2016 found SQM extracted more groundwater than legally permitted for consecutive years, something authorities said “put the stability of the ecosystem in extreme risk.” SQM later accused its neighbor of doing the same. In 2022, SQM was ordered to pay $51.7 million to correct the damages caused by six infractions, including transparency concerns and contamination of fresh water wells.

SQM spokesman Barrera would not directly respond when asked if it can say definitively that it hasn’t damaged the environment. “With the information we have available, we can say there has been no fundamental change in the surroundings (of the mines),” he said.

He attributed court rulings and criticisms to “disinformation,” and cast blame on state-run copper mines, also heavy water users. The mine’s director said the water the lithium mines pump is slowly refilled by rain and fresh water in the mountains, a water source for local communities.

At Albemarle, the other mine occupying the flat, one spokesperson insisted that the brine water it pumps “is not water” because it is not drinkable.

Nearly a dozen scientists said it is almost inconceivable that the heavy water use would have no environmental impact.

Garcés, the Chilean hydrologist, added that the extraction may even speed the effects of climate change.

“The Earth is warming, and you are evaporating more water in a shorter amount of time,” she said. “Through this industry you are accelerating water loss.”

 

Boom in Chile

 

Lithium mining also has sparked an economic boom in parts of Chile.

Since the beginning of the native Atacama people, generations of Ramon Torres’ family guided their pack of goats along the rolling hills of Peine, a town sitting at the mouth of Chile’s salt flats.

When companies started extracting lithium in the early 1980s, Ramon Torres was among the people to raise his hand. He worked the tinted pools, going from subsisting like his parents and grandparents to saving.

Today, he sits on the porch of his small brick house scrolling through his smartphone, purchased with the money he earned from the mine. Cherry-red trucks loaded with miners rumble past his home on their way to a long day of work as the sun rises.

“There is development, but there’s also the water issue. And they contradict each other,” he said. “Because everyone needs money, everyone also needs the basics, like health care and education.”

That same tension has divided mining towns such as his in Chile and Argentina: The economic benefits of lithium are undeniable. Mining makes up a whopping 62% of Chile’s exports, a crucial backbone to the country’s economy.

The money that the mines have brought has rippled across Peine. Torres now works building homes for and rents to mine workers, who have flooded the region.

Companies advertise investment projects in nearby towns, touting mobile dental clinics and soccer fields, in many ways filling the endemic absence of the Chilean government.
