Raquel Celina Rodriguez watches her step as she walks throughout the Vega de Tilopozo in Chile’s Atacama salt flats.

It is a wetland, recognized for its groundwater springs, however the plain is now dry and cracked with holes she explains had been as soon as swimming pools.

“Earlier than, the Vega was all inexperienced,” she says. “You could not see the animals by means of the grass. Now every thing is dry.” She gestures to some grazing llamas.

For generations, her household raised sheep right here. Because the local weather modified, and rain stopped falling, much less grass made that a lot more durable.

Nevertheless it worsened when “they” began taking the water, she explains.

“They” are lithium firms. Beneath the salt flats of the Atacama Desert lie the world’s largest reserves of lithium, a comfortable, silvery-white metallic that’s an integral part of the batteries that energy electrical automobiles, laptops and photo voltaic vitality storage.

Because the world transitions to extra renewable vitality sources, the demand for it has soared.

In 2021, about 95,000 tonnes of lithium was consumed globally – by 2024 it had greater than doubled to 205,000 tonnes, based on the Worldwide Power Company (IEA).

By 2040 it is predicted to rise to greater than 900,000 tonnes.

A lot of the improve might be pushed by demand for electrical automobile batteries, the IEA says.

Locals say environmental prices to them have risen too.

So, this hovering demand has raised the query: is the world’s race to decarbonise unintentionally stoking one other environmental drawback?

Flora, flamingos and shrinking lagoons

Chile is the second-largest producer of lithium globally after Australia. In 2023, the federal government launched a Nationwide Lithium Technique to ramp up manufacturing by means of partly nationalising the business and inspiring non-public funding.

Its finance minister beforehand stated the rise in manufacturing might be by as much as 70% by 2030, though the mining ministry says no goal has been set.

This yr, a serious milestone to that’s set to be reached.

A deliberate joint enterprise between SQM and Chile’s state mining firm Codelco has simply secured regulatory approval for a quota to extract at the very least 2.5 million metric tonnes of lithium metallic equal per yr and increase manufacturing till 2060.

Chile’s authorities has framed the plans as a part of the worldwide struggle towards local weather change and a supply of state revenue.

Mining firms predominantly extract lithium by pumping brine from beneath Chile’s salt flats to evaporation swimming pools on the floor.

The method extracts huge quantities of water on this already drought-prone area.

Faviola Gonzalez is a biologist from the native indigenous neighborhood working within the Los Flamencos Nationwide Reserve, in the midst of the Atacama Desert, residence to huge salt flats, marshes and lagoons and a few 185 species of birds. She has monitored how the native surroundings is altering.

“The lagoons listed below are smaller now,” she says. “We have seen a lower within the copy of flamingos.”

She stated lithium mining impacts microorganisms that birds feed on in these waters, so the entire meals chain is affected.

She factors to a spot the place, for the primary time in 14 years, flamingo chicks hatched this yr. She attributes the “small reproductive success” to a slight discount in water extraction in 2021, however says, “It is small.”

“Earlier than there have been many. Now, just a few.”

The underground water from the Andes, wealthy in minerals, is “very previous” and replenishes slowly.

“If we’re extracting a variety of water and little is getting into, there may be little to recharge the Salar de Atacama,” she explains.

Injury to flora has additionally been present in some areas. On property within the salt flats, mined by the Chilean firm SQM, nearly one-third of the native “algarrobo” (or carob) timber had began dying as early as 2013 as a result of impacts of mining, based on a report printed in 2022 by the US-based Nationwide Assets Protection Council.

However the situation extends past Chile too. In a report for the US-based Nationwide Assets Protection Council in 2022, James J. A. Blair, an assistant professor at California State Polytechnic College, wrote that lithium mining is “contributing to situations of ecological exhaustion”, and “could lower freshwater availability for natural world in addition to people”.

He did, nonetheless, say that it’s tough to seek out “definitive” proof on this subject.

Mitigating the harm

Environmental harm is in fact inevitable on the subject of mining. “It is onerous to think about any sort of mining that doesn’t have a damaging influence,” says Karen Smith Stegen, a political science professor in Germany, who research the impacts of lithium mining the world over.

The problem is that mining firms can take steps to mitigate that harm. “What [mining companies] ought to have carried out from the very starting was to contain these communities,” she says.

For instance, earlier than pumping lithium from underground, firms might perform “social influence assessments” – critiques which take into consideration the broad influence their work could have on water, wildlife, and communities.

Extracting lithium entails pumping brine from beneath Chile’s salt flats to evaporation swimming pools on the floor

For his or her half, mining firms now say they’re listening. The Chilean agency SQM is likely one of the major gamers.

At one in every of their vegetation in Antofagasta, Valentín Barrera, Deputy Supervisor of Sustainability at SQM Lithium, says the agency is working carefully with communities to “perceive their issues” and finishing up environmental influence assessments.

He feels strongly that in Chile and globally “we’d like extra lithium for the vitality transition.”

He provides that the agency is piloting new applied sciences. If profitable, the concept is to roll these out of their Salar de Atacama vegetation.

These embrace each extracting lithium instantly from brine, with out evaporation swimming pools, and applied sciences to seize evaporated water and re-inject it into the land.

“We’re doing a number of pilots to grasp which one works higher with a purpose to improve manufacturing however scale back at the very least 50% of the present brine extraction,” he stated.

He says the pilot in Antofagasta has recovered “multiple million cubic metres” of water. “Beginning in 2031, we’re going to begin this transition.”

However the locals I spoke to are sceptical. “We imagine the Salar de Atacama is like an experiment,” Faviola argues.

She says it is unknown how the salt flats might “resist” this new expertise and the reinjection of water and fears they’re getting used as a “pure laboratory.”

Sara Plaza, whose household additionally raised animals in the identical neighborhood as Raquel, is anxious in regards to the modifications she has seen in her lifetime.

She remembers water ranges dropping from as early as 2005 however says “the mining firms by no means stopped extracting.”

‘The businesses give the neighborhood somewhat cash, however I would want no cash. I would want to dwell off nature and have water to dwell’

Sara turns into tearful when she speaks in regards to the future.

“The salt flats produce lithium, however at some point it is going to finish. Mining will finish. And what are the individuals right here going to do? With out water, with out agriculture. What are they going to dwell on?”

“Perhaps I will not see it due to my age, however our youngsters, our grandchildren will.”

She believes mining firms have extracted an excessive amount of water from an ecosystem already struggling from local weather change.

“It is very painful,” she provides. “The businesses give the neighborhood somewhat cash, however I would want no cash.

“I would want to dwell off nature and have water to dwell.”

The influence of water shortages

Sergio Cubillos is head of the affiliation for the Peine neighborhood, the place Sara and Raquel dwell.

He says Peine has been pressured to alter “our complete consuming water system, electrical system, water therapy system” due to water shortages.

“There may be the difficulty of local weather change, that it does not rain anymore, however the principle influence has been attributable to extractive mining,” he says.

He says because it began within the Nineteen Eighties, firms have extracted tens of millions of cubic metres of water and brine – lots of of litres per second.

“Selections are made in Santiago, within the capital, very removed from right here,” he provides.

He believes that if the President desires to struggle local weather change, like he stated when he ran for workplace, he must contain “the indigenous individuals who have existed for millennia in these landscapes.”

Sergio understands that lithium is essential for transitioning to renewable vitality however says his neighborhood shouldn’t be the “bargaining chip” in these developments.

His neighborhood has secured some financial advantages and oversight with firms however is fearful about plans to ramp up manufacturing.

He says whereas searching for applied sciences to cut back the influence on water is welcome that “cannot be carried out sitting at a desk in Santiago, however somewhat right here within the territory.”

Sergio Cubillos says his neighborhood shouldn’t be a “bargaining chip”

Chile’s authorities stresses there was “ongoing dialogue with indigenous communities” and so they have been consulted over the brand new Codelco-SQM three way partnership’s contracts to deal with issues round water points, new applied sciences and contributions to the communities.

It says growing manufacturing capability might be primarily based on incorporating new applied sciences to minimise the environmental and social influence and that the excessive “worth” of lithium as a consequence of its position within the world vitality transition might present “alternatives” for the nation’s financial growth.

Sergio although worries about their space being a “pilot challenge” and says if the influence of latest expertise is damaging, “We are going to put all our energy into stopping the exercise that might finish with Peine being forgotten.”

A small a part of a worldwide dilemma

The Salar de Atacama is a case examine for a worldwide dilemma. Local weather change is inflicting droughts and climate modifications. However one of many world’s present options is – based on locals – exacerbating this.

There’s a widespread argument from individuals who help lithium mining: that even when it damages the surroundings, it brings enormous advantages by way of jobs and money.

Daniel Jimenez, from lithium consultancy iLiMarkets, in Santiago, takes this argument a step additional.

He claims that environmental harm has been exaggerated by communities who need a pay-out.

What’s occurring within the Salar de Atacama is a case examine for a worldwide dilemma – and debate

“That is about cash,” he argues. “Corporations have poured some huge cash into enhancing roads, faculties – however the claims of communities actually return to the very fact they need cash.”

However Prof Stegen is unconvinced. “Mining firms at all times wish to say, ‘There are extra jobs, you are going to get extra money’,” she says.

“Properly, that is not notably what a variety of indigenous communities need. It truly might be disruptive if it modifications the construction of their very own conventional financial system [and] it impacts their housing prices.

“The roles will not be the be all and finish all for what these communities need.”

‘Our sacred birds which might be disappearing,’ says Faviola

In Chile, these I spoke to did not speak about wanting extra money. Nor are they against measures to sort out local weather change. Their major query is why they’re paying the worth.

“I believe for the cities perhaps lithium is nice,” Raquel says. “Nevertheless it additionally harms us. We do not dwell the life we used to dwell right here.”

Faviola doesn’t assume electrifying alone is the answer to local weather change.

“All of us should scale back our emissions,” she says. “In developed nations just like the US and Europe the vitality expenditure of individuals is far larger than right here in South America, amongst us indigenous individuals.”

“Who’re the electrical automobiles going to be for? Europeans, People, not us. Our carbon footprint is far smaller.”

“Nevertheless it’s our water that is being taken. Our sacred birds which might be disappearing.”
