‘It’s Russian roulette’: alarm as Europe backs critical minerals mines in water-stressed regions

The European Commission plans to rewrite the EU’s flagship water protection law to speed up the development of critical minerals mines, despite many being located in drying and water-stressed regions, analysis has found. Mining is a water-intensive industry, requiring large volumes of water for ore processing, dust suppression, waste management and mine dewatering. While modern projects recycle water, they still require significant amounts, and in water-stressed regions those demands can add to pressure on already stretched rivers, aquifers and water supplies. Analysis and mapping by Watershed Investigations, shared with the Guardian, found that more than half of the 33 planned new or expanded mines designated as “strategic projects” under the EU’s Critical Raw Materials Act are located in areas that have been drying over the past two decades, according to Nasa satellite data. Nearly half are in zones that experienced drought conditions in the past three months, according to EU data, and a quarter are in regions deemed water-stressed. Drought conditions in Europe – graphic Six of the strategic mines are planned for highly water-stressed areas in Spain, with others in Portugal and Greece. All three countries rank among the top 10 EU nations with the worst water scarcity, according to the European Environment Agency. In 2024, the Spanish region of Catalonia declared a state of emergency over its worst ever drought, and water-use restrictions were imposed in Andalucía. …
