Dangers of Lithium Mining: 7 Key South America Risks (2025)

“Lithium mining in South America uses up to 2 million liters of water per ton of lithium extracted.”

Summary: Environmental and Socioeconomic Dangers of Lithium Mining in 2025

As global demand for lithium surges, driven by the electrification of transport and the proliferation of renewable energy storage systems, lithium mining has become a critical industry—especially across South America’s Lithium Triangle (Argentina, Bolivia, Chile). However, the dangers of lithium mining extend well beyond its role in green technologies. Extraction processes frequently threaten water, agriculture, forestry, and the very fabric of local communities, particularly in vulnerable regions by 2025.

The most significant environmental impacts include water scarcity and soil degradation, which compromise surrounding agricultural regions, endanger food security for farmers, and reduce biodiversity within forests. Pollution, chemical contamination, and air quality degradation imperil nearby rural communities, disrupt traditional practices, and contribute to socioeconomic tension among indigenous groups. As the world seeks sustainable solutions, recognizing and mitigating the dangers of lithium mining is essential for balanced development.

Understanding the Global Surge in Lithium Demand

Demand for lithium is increasing rapidly, fueled largely by the shift toward electric vehicles (EVs), renewable energy storage systems, and digital devices reliant on lithium-ion batteries. The Green Transition, underpinned by these technologies, is projected to make lithium the world’s most sought-after critical mineral by 2025.

• The electrification of transport is a principal driver, as nations transition away from fossil fuels and towards green alternatives.
• The proliferation of energy storage systems in both grid and off-grid applications amplifies the urgency to secure reliable lithium supplies.
• South America’s Lithium Triangle, containing more than half of the world’s known lithium reserves, has become the epicenter of global extraction and associated risks.

The dangers of lithium mining are not abstract or distant—they are real, persistent, and deeply enmeshed in the physical and socioeconomic landscapes of South America.

Key Extraction Methods: Hard Rock vs Brine—South America in Focus

Lithium extraction occurs primarily via two methods, each with distinct but pronounced environmental impacts on surrounding ecosystems:

• Hard Rock Mining (Spodumene):
  Extracting lithium from spodumene ores via open-pit mines is resource and energy-intensive. This method causes deforestation, soil erosion, and loss of biodiversity in adjacent forests, while also fragmenting habitats and disrupting local climate conditions essential for sustaining agricultural ecosystems. Deforestation near mining sites is particularly damaging in arid locations, exacerbating climate changes.
• Brine Extraction:
  In brine extraction, lithium-rich saline groundwater is pumped out from underground reservoirs to large evaporation ponds. This process is dominant across the Lithium Triangle (northern Chile, Argentina, southern Bolivia)—arid to semi-arid regions with already limited water resources. Extracting one ton can require up to 2 million liters (about 500,000 gallons) of water, intensifying water scarcity and threatening the sustainability of local agriculture and forestry.

Both extraction methods lead to lowered water availability for local farmers and livestock owners, threaten food security, and often result in contamination of the soil and water near mining sites.

“By 2025, 65% of lithium mines in South America risk affecting local agriculture due to groundwater depletion.”

Dangers of Lithium Mining: 7 Critical South America Risks (2025)

The dangers of lithium mining in South America for 2025 and beyond revolve around seven key risks. Viewed through the lens of sustainability and environmental responsibility, each of these risks poses significant threats to water availability, agriculture, forestry, and the livelihoods of nearby communities.

1. 1. Water Depletion and Scarcity in Arid Regions

   Lithium brine extraction consumes vast amounts of water—up to 2 million liters per ton. In the Lithium Triangle (spanning parts of Argentina, Bolivia, Chile), vast withdrawals from delicate underground aquifers lead to reduced availability of water for farmers, livestock, and rural communities. This intensifies existing water shortages, particularly in already arid locations.

   Groundwater levels near mining sites drop, leading to jeopardized food security and threatening traditional agricultural practices among indigenous and rural communities. Reduced water means lower crop yields and diminished pasturelands.

2. 2. Soil Salinization and Degradation of Productive Soils

   Discharge of extracted brines—usually high in salts and chemicals—changes the salinity of both soil and water, leading to the degradation of productive soils, a decline in crop yields, and loss of biodiversity. Salinization is one of the most insidious side effects, as it may take years before impacts become visible, but is often irreversible.

   Productive soils surrounding brine projects often suffer, resulting in lower food production and broader impacts on local food systems—a critical issue in rural South America.

3. 3. Agricultural and Forestry Impacts

   Water withdrawal and changes in soil chemistry directly threaten agricultural regions adjacent to mining sites. With reduced water availability and salinity changes, farmers’ ability to irrigate crops and manage pasturelands for livestock is compromised.

   • Loss of forest cover due to mine expansion, clearing, and infrastructure development further fragments animal habitats and affects microclimates essential for sustainable agriculture.
   • Both subsistence and commercial farmers in the region face lowered productivity and increased risk of food insecurity.

4. 4. Threats to Biodiversity and Forest Ecosystems

   Deforestation for mine infrastructure, access roads, and evaporation ponds—especially via open-pit mining—causes habitat fragmentation and threatens local wildlife. The Lithium Triangle is home to unique forests and wetlands that play a crucial role in global biodiversity. Reduction in forest cover often has pronounced effects on local climate conditions, impacting life beyond direct mining areas.

5. 5. Chemical Pollution and Contamination Risks

   The use of hydrochloric acid, lime, solvents, and other chemicals in lithium extraction and processing creates contamination risks for local soils and water. Improper disposal, spills, or leakages can lead to pollution and long-lasting damage to both terrestrial and aquatic systems.

   Farmers and rural communities near these sites are often first to experience the consequences, from the loss of fish and aquatic life to outbreaks of disease and respiratory issues caused by airborne particulates.

6. 6. Socioeconomic Disruption and Infrastructure Pressure

   Mining expansion brings an influx of workers and demands additional infrastructure. This strains local roads, health, and water systems, often without proportional benefit to communities.

   Indigenous groups and rural populations may face land dispossession, disruption to traditional practices, and inequitable sharing of mining proceeds. The strain on cultural coherence and social frameworks can lead to conflict and migration.

7. 7. Water Conflicts and Resource Insecurity

   As water becomes more scarce, conflicts emerge among stakeholders—miners, farmers, local governments, and indigenous leaders. With groundwater depletion projected to worsen by 2025, disputes over resource allocation will likely increase.

   These conflicts threaten long-term regional stability, undermining sustainable development goals and community well-being.

Socioeconomic Impacts on Local Communities

While the environmental dangers of lithium mining are evident, the deeper socioeconomic consequences are equally concerning, especially when viewed through the lens of agriculture, rural communities, and indigenous practices in 2025 and beyond.

• Displacement and Land Dispossession: Many lithium reserves are beneath indigenous territories or smallholder farmland. Mine expansion and associated infrastructure can push rural and indigenous residents off ancestral lands, breaking long-standing agricultural traditions and cultural ties.
• Uneven Economic Benefits: While global investors and mining corporations profit handsomely, the direct benefits for local communities are often limited. Small farmers and indigenous groups commonly receive inadequate compensation, while their primary resources and means of survival—land, water, forests—sustain irreversible damage.
• Stress on Local Infrastructure: A sudden population influx for mining operations puts immense pressure on already fragile health, water, and road networks. These strains disrupt economic life and essential services for residents, leading to increased poverty and social tension.
• Loss of Agricultural Livelihoods: With water scarcity and soil degradation, local farmers experience lower crop yields and may be forced out of agriculture altogether—compromising food security and deepening poverty cycles.
• Cultural Erosion: Traditional agricultural and forestry practices, community rituals, and indigenous knowledge systems are threatened as rural populations are displaced and the environment that sustains them is degraded.
