The global push for clean energy is intensifying pressure on lithium-rich regions of northern Chile, where Indigenous communities warn that large-scale extraction risks undermining fragile ecosystems, water resources, and traditional ways of life.

Chile, one of the world’s leading producers of lithium, has become central to the energy transition as demand for electric vehicle batteries and energy storage systems accelerates. However, in the high-Andean salt flats where much of the mineral is found, local communities say the costs of extraction are being borne disproportionately at the territorial level.

In the Atacama region, the Colla Indigenous community of Pastos Grandes lives near the Salar de Maricunga, a high-altitude ecosystem characterized by salt flats, wetlands, and limited freshwater sources. The environmental balance in the region depends on underground aquifers and scarce water flows that sustain both human livelihoods and biodiversity.“Living in our territory today means resisting,” said Zulema Mancilla, a member of the Colla community.

She described growing concerns over water depletion linked to lithium extraction, noting that the pumping of underground aquifers has reduced water availability in downstream areas where communities live and work.“We have serious problems with water,” she said, adding that while extraction projects are advancing, local populations face increasing environmental stress.Further north, in the highlands of Tarapacá near the Bolivian border, Aymara communities rely on pastoralism and subsistence agriculture, including llama and alpaca herding and quinoa cultivation.

These activities depend on high-altitude wetlands, known locally as “bofedales,” which are particularly sensitive to changes in water availability.“If this lithium project goes ahead, it will become an enormous ‘sacrifice zone’ for our people,” said Juana Mamani Flores of the Panavinto community, highlighting concerns over the long-term viability of local livelihoods.

For many Indigenous residents, the issue extends beyond environmental impact to encompass cultural and spiritual dimensions. Eva Mamani, also from Panavinto, described the territory as intrinsically connected to community identity and belief systems.“The waters have spirit, the shrubs have spirit, the mountains have spirit,” she said, framing environmental protection as both a practical and cultural imperative.

United Nations human rights officials say such perspectives underscore the need to reframe discussions around the energy transition. Jan Jarab, Regional Representative for South America, noted that areas targeted for lithium extraction are not uninhabited resource zones but living territories shaped by long-standing social and cultural systems.

While communities acknowledge the importance of addressing climate change and transitioning to cleaner energy sources, they emphasize the need for clearer information and stronger safeguards. Samuel García, an Aymara leader, said there is a lack of reliable data on the potential environmental impacts of lithium extraction.“We do not have a specific and reliable study of the damage,” he said, pointing to uncertainty surrounding long-term consequences.

The debate, according to observers, is shifting from whether lithium extraction is necessary to how it is conducted and who bears its costs. UN Human Rights has facilitated dialogues among Indigenous leaders, governments, and industry stakeholders across the “lithium triangle,” a region spanning Chile, Argentina, and Bolivia that holds more than half of the world’s lithium reserves.

These discussions focus on aligning extraction practices with international human rights standards, particularly the principle of free, prior, and informed consent for Indigenous Peoples. Jarab emphasized that affected communities must be involved in decision-making processes and have the opportunity to influence project outcomes.“Communities themselves best understand their needs and know how to care for the environment,” he said, adding that consultation mechanisms should enable equitable participation and benefit-sharing.

The UN has framed the issue within the concept of a “just transition,” warning that without adequate safeguards, the shift to renewable energy could replicate historical patterns of extractive industries, where economic gains are concentrated while environmental and social costs are localized.The role of both governments and corporations is central to this process.

Under the UN Guiding Principles on Business and Human Rights, companies involved in lithium extraction are expected to conduct due diligence, assess environmental and social impacts, and establish mechanisms to address harm. States, in turn, are responsible for regulating these activities and ensuring compliance with human rights obligations.

Jarab noted that state-owned enterprises, in particular, are expected to uphold higher standards of accountability, given their direct link to public policy and governance.The broader debate reflects a tension between global climate objectives and local realities. As countries accelerate decarbonization efforts, the extraction of critical minerals such as lithium has become essential.

However, the Chilean case illustrates the complexity of ensuring that environmental goals do not come at the expense of vulnerable communities.For Indigenous groups, the stakes extend beyond economic considerations to the preservation of cultural identity and long-term sustainability.

Decisions made in the coming years are likely to shape not only environmental outcomes but also the future of traditional ways of life in the region.The discussion, UN officials say, is ultimately about ensuring that the benefits of the energy transition are distributed equitably, and that its implementation does not undermine the rights of those living in resource-rich territories.

A controversial reform to Ley de Glaciares has intensified debate in Argentina, as the government moves to relax environmental protections in high-altitude regions to facilitate mining investment.

The decision has triggered protests from environmental groups and raised concerns among communities dependent on glacier-fed water systems.The shift follows years of tensions surrounding mining operations such as the Veladero mine, a gold and silver project that began operating in 2005 in San Juan Province.

The mine, jointly owned by Barrick Mining Corporation and Shandong Gold, has long been at the center of environmental scrutiny. A cyanide spill in 2015 polluted rivers in the region, raising concerns about downstream water safety in the Jáchal basin, although subsequent studies indicated that contamination levels remained within safe limits.

Additional spills reported in 2016 and 2017 remain under investigation.Local residents and environmental advocates have argued that operations at Veladero violate glacier protection laws, which were originally designed to prohibit industrial activity in sensitive high-mountain ecosystems.

These concerns have persisted despite legal challenges by mining companies, including attempts to have the law declared unconstitutional, which were rejected by Argentina’s Supreme Court.The newly approved reform, backed by President Javier Milei, introduces significant changes to how glacier protection is applied.

Passed by 137 votes to 111 in the Chamber of Deputies following earlier Senate approval, the legislation allows provincial authorities to determine which glaciers and periglacial areas qualify for protection.

The criteria hinge on whether these ice formations serve a “relevant water function,” effectively decentralizing decision-making that was previously governed by national standards.

Government officials argue that the reform is essential to unlocking Argentina’s mineral wealth, particularly as global demand for critical resources such as lithium and copper rises in response to the energy transition.

Milei described the previous framework as overly restrictive, stating that it created “artificial obstacles” and prevented development even in areas lacking significant environmental value.However, critics contend that the changes weaken a foundational environmental safeguard.

Andrés Nápoli, executive director of the Foundation of Environment and Natural Resources, warned that the reform undermines protections for key water reserves. He argued that linking glacier exploitation to sustainable energy goals presents a contradiction, emphasizing that glaciers play an essential role in maintaining ecological balance.

Environmental groups estimate that approximately 7 million people, or 16 percent of Argentina’s population, rely on glacier-fed water systems. Beyond supplying rivers, glaciers regulate fragile ecosystems that are increasingly vulnerable to climate change.

In the country’s northwest, scientists report that glacier mass has declined by around 17 percent over the past decade, heightening concerns about long-term water availability.The reform has prompted public demonstrations, including protests organized by Greenpeace outside the National Congress.

Several activists were detained earlier this year during a demonstration coinciding with Senate deliberations. Protesters argue that transferring authority to provincial governments risks prioritizing short-term economic gains over environmental sustainability.

Supporters of the reform, including provincial leaders in resource-rich regions, maintain that the previous law was overly broad and hindered investment in areas where environmental impact is minimal. Luis Lucero stated during a congressional hearing that framing mining and environmental protection as mutually exclusive is misleading, describing it as a misconception that should be removed from public discourse.

Experts caution that the issue extends beyond technical definitions of glaciers. Ruiz noted that glaciers are dynamic systems whose role in water supply can vary over time, making it difficult to assess their importance through fixed criteria.

He argued that the debate is ultimately political, centering on who has the authority to determine what constitutes a resource worth protecting.In communities such as Jáchal, the stakes are immediate and tangible. Residents have expressed fears about water contamination and long-term environmental degradation.

Activists like Zeballos, a local campaigner, have taken personal measures such as avoiding river water, citing concerns over safety. For many, the issue is framed not only as an environmental question but as one of survival.The reform underscores the broader challenge facing resource-rich nations seeking to balance economic development with environmental preservation.

As Argentina positions itself as a key supplier of minerals critical to global energy systems, tensions between national growth strategies and local ecological concerns are likely to intensify.
