Argentina Eases Glacier Mining Rules, Raising Water Security Questions
Argentina has approved a controversial reform easing restrictions on mining in glacier regions, sparking strong opposition from environmental groups and key industries.
The move effectively weakens the landmark Glacier Law of 2010, which made Argentina the first nation in the world to legally protect its glaciers as strategic water reserves, banning all mining and exploration in those areas.
Backed by President Javier Milei, the reform shifts decision-making power to provincial governments. Milei defended the change as a way to “empower the provinces to utilise their resources,” arguing it enables mining in areas “where there was nothing to protect.”
Under the new framework, glaciers not permanently covered in ice will remain protected for now, but only until provinces determine whether they are critical for water supply.
The reform has alarmed winemakers in Mendoza, the country’s wine-producing heartland. Vineyards there depend heavily on meltwater from the Andes Mountains for irrigation, and producers fear mining activity could disrupt or contaminate this vital resource.
Concerns extend far beyond one region. Argentina is home to 16,968 glaciers that feed 36 river basins across 12 provinces, supporting water access for around seven million people. Environmentalists warn that loosening protections could jeopardise long-term water security in a country already facing climate-related pressures.
As provinces begin reassessing their glacier resources, the reform sets up a contentious debate between economic development and environmental preservation—one with potentially far-reaching consequences.
