ICMM Global Water Dataset Highlights Escalating Water Risks Threatening Mining Operations and the Global Clean Energy Transition

Recent Developments:

• The International Council on Mining and Metals (ICMM) has released the Global Mining and Metals Water Dataset, the first global assessment mapping physical water risks across mining and metals facilities.
• The report finds that nearly two-thirds of mining and metals processing facilities worldwide are exposed to at least one major physical water hazard, raising concerns over the long-term sustainability of critical mineral supply chains essential for the global clean energy transition.

About the Global Mining and Metals Water Dataset Report:

Overview:

• The Global Mining and Metals Water Dataset is the first comprehensive cross-commodity assessment examining the exposure of mining and metals operations to physical water risks worldwide.
• The assessment was prepared by the International Council on Mining and Metals (ICMM) in collaboration with research partners using geospatial analysis.
• The study overlays the locations of nearly 12,000 mining and metals facilities across 148 countries and regions with globally recognised water-risk indicators.
• The report evaluates five major physical water hazards, namely baseline water stress, water depletion, drought, flood risk and interannual water variability, enabling facility-level risk assessment.

About the International Council on Mining and Metals (ICMM):

• ICMM is a global industry organisation established in 2001 to promote responsible mining, environmental sustainability and social performance.
• It brings together leading mining companies and regional mining associations to develop common standards for sustainable mineral extraction.
• The Council promotes responsible management of water resources, biodiversity, mine waste, climate change and community engagement, aligning mining practices with the Sustainable Development Goals (SDGs).

Major Findings of the Report:

Water Stress as the Dominant Risk:

• 38% of global facilities are located in river basins experiencing high or extremely high baseline water stress or arid climatic conditions.
• More than 70% of these facilities simultaneously experience high groundwater depletion, indicating severe pressure on freshwater availability.
• Competition between mining operations, agriculture, industries and domestic users has emerged as the most widespread physical water challenge.

Growing Drought Vulnerability:

• Around 27% of mining facilities are exposed to severe drought risk globally.
• The risk reaches 81% across Africa and the Middle East, while countries such as Zambia, Ghana and Uzbekistan show almost universal drought exposure.
• Persistent drought reduces operational efficiency, increases production costs and threatens long-term mine viability.

Flood Risks in Mineral Processing:

• Although global flood exposure averages 14%, several mineral processing activities face substantially higher flood vulnerability.
• Steel production, alumina refining, molybdenum processing and aluminium smelting exhibit elevated exposure because of their dependence on water-intensive infrastructure.
• Extreme flooding can damage processing plants, disrupt logistics and contaminate surrounding ecosystems through tailings failures.

Interannual Water Variability:

• About 16% of global facilities experience large year-to-year fluctuations in water availability.
• Oceania, particularly Australia, records exceptionally high variability, making long-term operational planning increasingly difficult.
• Climate change is expected to intensify hydrological uncertainty and increase operational risks.

Compound Water Risk Hotspots:

• Nearly 5% of mining facilities face simultaneous exposure to three or more major water hazards.
• Major hotspots include Chile, Peru, the western United States, southern Africa, northern China, central India and western Australia.
• Compound risks significantly reduce resilience because multiple hazards occur together rather than independently.

Risks to Critical Energy Transition Minerals:

• Minerals essential for renewable energy technologies exhibit above-average exposure to physical water risks.
• Platinum Group Elements, manganese, copper and lithium are increasingly produced in water-stressed regions.
• Water scarcity could become a major constraint on manufacturing electric vehicles, solar panels, wind turbines and battery storage systems.

Mining–Water Nexus: How Mining Affects Water Resources:

High Freshwater Consumption:

• Mining requires substantial quantities of water for ore processing, dust suppression, slurry transportation, drilling and equipment cooling.
• Large-scale withdrawals often increase competition with agriculture, industries and local communities, particularly in semi-arid regions.

Groundwater Depletion:

• Continuous groundwater pumping for mine dewatering lowers regional water tables and reduces groundwater recharge.
• Excessive extraction may permanently alter aquifer systems, affecting drinking water security and agricultural productivity.

Water Pollution:

• Tailings storage facilities, acid mine drainage and untreated industrial effluents may release heavy metals, toxic chemicals and suspended sediments into nearby rivers and groundwater.
• Such contamination threatens aquatic biodiversity, drinking water quality and ecosystem health.
• Recent mining-related tailings failures have reinforced the need for stronger environmental safeguards and monitoring.

Alteration of Natural Hydrology:

• Open-pit excavation, waste dumps and land clearance modify natural drainage patterns and watershed hydrology.
• These changes increase soil erosion, sediment transport, flash floods and habitat degradation, reducing ecosystem resilience.

Significance of the Findings:

Energy Transition Challenge:

• Critical minerals such as copper, lithium, nickel and rare earth elements form the backbone of the global low-carbon economy.
• Water scarcity may become a major bottleneck for expanding renewable energy infrastructure despite growing mineral demand.
• Sustainable mineral production is therefore inseparable from sustainable water management.

Supply Chain Risks:

• Climate-induced droughts and floods can interrupt mining operations, reduce global mineral supply and increase commodity price volatility.
• Supply disruptions may delay renewable energy projects and increase manufacturing costs for clean technologies.

Socio-Economic Consequences:

• Water competition often intensifies conflicts among mining companies, farmers, indigenous communities and local governments.
• Social unrest, litigation and environmental protests can delay mining projects and reduce investor confidence.

Financial and Regulatory Risks:

• Companies failing to manage water sustainably may face regulatory penalties, higher operational costs, insurance liabilities and stranded assets.
• Investors increasingly evaluate Environmental, Social and Governance (ESG) performance before financing mining projects.

Way Forward:

Integrated Catchment-Based Water Management:

• Water governance should move beyond individual mining sites towards river basin and catchment-level planning involving governments, industries, communities and environmental agencies.
• Integrated Water Resources Management (IWRM) principles should guide water allocation and ecosystem conservation.

Strengthening Water Efficiency:

• Mining companies should expand closed-loop water recycling, wastewater reuse, desalination technologies and alternative water sources to reduce freshwater dependence.
• Circular water management can improve both operational resilience and environmental sustainability.

Improving Transparency and Monitoring:

• Public disclosure of facility-level water withdrawal, consumption, recycling and discharge data should become standard industry practice.
• Greater transparency supports informed regulation, investor confidence and scientific risk assessment.

Integrating Water into Critical Mineral Policies:

• Governments should incorporate water availability, climate resilience and watershed carrying capacity into critical mineral strategies and mining approvals.
• Environmental impact assessments should explicitly evaluate cumulative water risks before granting new mining leases.
