Flora & Fauna

Andean Flamingo (Phoenicoparrus andinus)
Status: Vulnerable
Threat: Water depletion and loss of lagoon habitats in the Salar de Atacama due to brine extraction disrupt their feeding and nesting grounds.
James's Flamingo / Puna Flamingo (Phoenicoparrus jamesi)
Status: Near Threatened
Threat: Disappearance of high-altitude saline lakes and lagoons due to lithium mining water-use impacts their food supply (diatoms).

Ecology Impact

The trade deal's focus on critical minerals like lithium and copper from Chile could intensify mining in fragile ecosystems like the hyper-arid Atacama Desert. This water-intensive extraction depletes local aquifers, leading to the subsidence of salt flats (salars) and the disappearance of critical wetland lagoons.

Science & Tech Angle

The underlying science involves the extraction of lithium from subterranean brine through solar evaporation in open pools, which requires evaporating approximately 500,000 liters of water per ton of lithium. This is contrasted with newer Direct Lithium Extraction (DLE) technologies that aim to reinject brine back into aquifers to minimize water loss.

Climate Change Link

Securing lithium and copper is vital for India's green energy transition, supporting its Nationally Determined Contributions (NDCs) under the Paris Agreement, such as achieving 500 GW of non-fossil fuel capacity by 2030. This aligns with India's domestic policy shift under the Mines and Minerals (Development and Regulation) Amendment Act, 2023, which de-listed lithium from atomic minerals to encourage private exploration and secure supply chains.

Sustainable Development

The partnership directly links to SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action) by securing materials for clean energy technologies. However, it poses challenges to SDG 6 (Clean Water and Sanitation) and SDG 15 (Life on Land) due to the high water footprint and ecological degradation associated with mineral extraction in Chile.

International Frameworks

Paris Agreement
Securing critical minerals like lithium and copper is essential for India to meet its NDCs, specifically transitioning to electric mobility and expanding renewable energy capacity.
Convention on the Conservation of Migratory Species of Wild Animals (CMS)
Both the Andean Flamingo and Puna Flamingo are listed under Appendix I of the CMS, which has a specific Memorandum of Understanding (MOU) on the Conservation of High Andean Flamingos and their Habitats to protect them from threats like mining.
