Sustainability Assessment of Lithium Mining in the Atacama Desert
Balancing the Global Energy Transition with Local Environmental Justice
Project Type: Multidisciplinary Case Study — Sustainability & Resource Governance
Year: 2019
Institution: University of Bath (UK)
Context
Lithium is a critical mineral powering the global transition to renewable energy and electric vehicles. Over half of the world’s lithium reserves are concentrated in the “Lithium Triangle” of Chile, Argentina, and Bolivia. This case study examined lithium brine extraction in the Salar de Atacama, Northern Chile — one of the driest regions on Earth — where large-scale evaporation ponds are used to extract lithium for battery production.
While lithium supports decarbonization globally, its extraction raises urgent concerns around water depletion, ecosystem damage, and indigenous community rights. This project explored whether growing lithium demand can be satisfied without causing environmental and social harm

Project Goals
1. Evaluate Environmental Sustainability
Assess water consumption, brine depletion, chemical processing, and ecological impacts associated with lithium extraction in arid ecosystems.2. Examine Social & Ethical Implications
Analyze impacts on indigenous Atacameño communities, including water access conflicts, land rights, and stakeholder inequality.3. Assess Economic & Policy Drivers
Understand global lithium demand linked to electric vehicle batteries and evaluate governance structures regulating extraction in Chile.4. Develop Balanced Sustainability Recommendations
Propose strategies to reconcile climate transition objectives with local environmental protection and social justice.
Project Context
Lithium in Chile is extracted from underground brine reservoirs through solar evaporation ponds — a process requiring significant water withdrawal in a region already experiencing extreme water scarcity.
Key challenges investigated included:
- Over-extraction of brine beyond recharge capacity
- Declining groundwater levels affecting agriculture and biodiversity
- Increased socio-environmental conflicts
- Limited transparency in hydrological monitoring
- Tension between national economic growth and local sustainability
The project incorporated real-world stakeholder perspectives, including:
- Mining companies
- Indigenous communities
- NGOs
- Chilean government agencies
Technical & Sustainability Scope
The assessment covered:
- Brine extraction and evaporation processes
- Water balance analysis and recharge limitations
- Chemical treatment and waste management
- Life Cycle Thinking and sustainability trade-offs
- Climate adaptation risks (extreme rainfall events impacting operations)
Frameworks applied:
- UN Sustainable Development Goals (SDGs) mapping
- Stakeholder Power–Interest analysis
- Environmental and Social Governance (ESG) evaluation
- Sustainability trade-off analysis
- Brine extraction and evaporation processes
- Water balance analysis and recharge limitations
- Chemical treatment and waste management
- Life Cycle Thinking and sustainability trade-offs
- Climate adaptation risks (extreme rainfall events impacting operations)
Frameworks applied:

Key Contributions
1. Environmental Risk Analysis
Evaluated hydrological stress and long-term ecosystem impacts associated with lithium brine extraction.2. Stakeholder Negotiation & Governance Assessment
Participated in multi-party negotiation exercises to reconcile competing interests between government, corporations, and local communities.3. Sustainability Trade-off Evaluation
Assessed the paradox between global decarbonization benefits and localized environmental degradation.4. Strategic Recommendations
Proposed improved monitoring transparency, stronger community consultation mechanisms, and resource efficiency strategies.Impact
This case study highlighted the complexity of responsible mineral extraction in the energy transition.
It demonstrated that sustainability in critical mineral supply chains requires:
- Integrated environmental governance
- Community-inclusive decision-making
- Transparent water monitoring
- Balanced economic development
The project strengthened my ability to analyze ESG risks in resource-intensive industries and evaluate sustainability beyond surface-level climate benefits.
