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.
