critical minerals – As demand for lithium, cobalt and rare earths surges, mining strains water and health in poorer communities. Misryoum reports on what must change.
A cleaner, tech-driven future is increasingly being built on polluted rivers and depleted water sources in some of the world’s poorest regions.
The global race for critical minerals used in batteries. electronics. wind power and defense systems is exposing a painful contradiction: the same materials that help drive the transition can come with heavy environmental and social costs at the mining sites.. Misryoum highlights a core concern raised by researchers focused on water. arguing that without tighter monitoring and regulation across supply chains. the poorest communities risk bearing the worst impacts.
In this context, water is emerging as the central battleground.. Misryoum reports that extraction processes for minerals such as lithium and rare earths can require large volumes of freshwater and can generate toxic waste and wastewater.. Where water is already scarce. mining can intensify competition with agriculture and ecosystems. while pollution can contaminate groundwater and surface water. leaving communities with fewer safe options for drinking and farming.
This matters because water stress and contamination tend to spread beyond the mine perimeter, shaping everyday health, local livelihoods and the ability of families to maintain stable food supplies.
Health consequences, too, are becoming harder to ignore.. Communities near mining operations describe illnesses linked to long-term exposure to heavy metals and contaminated water. including a range of chronic conditions.. Misryoum notes that reports point to especially severe outcomes in places where mining is intertwined with weak public services. making it more difficult for families to prevent. detect and treat illness.
Beyond health, the shift toward “clean energy” also risks tightening the squeeze on food systems.. When watersheds are affected by mining runoff or chemical contamination. irrigation can become unreliable and livestock can fall ill. threatening both household nutrition and local economies.. In mining regions, shortages and degraded water quality can translate into higher hardship for communities already facing economic pressure.
This matters because the energy transition’s benefits are often measured in technology and emissions, while the costs show up in water security, childhood health and local economic resilience.
So what can be done to prevent “sacrifice zones,” where human and ecological well-being is treated as collateral?. Misryoum emphasizes that the policy discussion increasingly centers on stronger governance across the supply chain. moving from voluntary commitments to binding rules.. Supporters argue that enforceable environmental and human-rights standards. more rigorous wastewater controls. independent monitoring. and stronger protections for affected communities could help reduce pollution and improve accountability.
Just as importantly, solutions are expected to extend beyond extraction sites.. That includes backing less water-intensive approaches. improving transparency so supply-chain impacts are visible. and reducing pressure on newly mined materials through longer product lifespans and recycling.. If governments and companies fail to address these issues early. Misryoum warns the transition could end up repeating an older pattern: growth built on communities that carry risks they were never meant to absorb.
This matters at the end of the chain as well. When the real human and environmental costs are hidden, consumers and policymakers lose leverage to demand safer practices, and the transition’s promise weakens.
