Argentina Relaxes Glacier Protections for Mining Expansion

Argentina's Congress approved an amendment that transfers authority over glacier regions from the national Argentine Institute for Snow, Ice and Environmental Sciences to provincial governments. The change allows mining activities in areas previously off-limits under the 2010 Glacier Law, which had banned all exploration to safeguard water reserves. President Javier Milei described the reform as a way to "empower the provinces to utilise their resources," potentially boosting economic opportunities in mineral-rich areas and affecting water supplies for millions of residents.

Congresswoman Natalia de la Sota warned that the reform endangers a vital resource, stating, "Without water, we can't even think about a growth and development project." Environmental groups like Greenpeace argue the bill overlooks the role of glaciers and periglacial environments as freshwater reservoirs, with biologist Agostina Rossi Serra noting that these areas "undergo a gradual thaw that feeds the rivers and streams of our country." There are 16,968 glaciers in Argentina that supply water to 36 river basins across 12 provinces, supporting seven million people and helping mitigate droughts in semi-arid regions like Mendoza.

Congresswoman Nancy Picón Martínez defended the legislation, asserting, "This law protects glaciers, no matter how much some people want us to believe otherwise." Governors from Catamarca, Jujuy, Salta, Mendoza and San Juan backed the bill, claiming the 2010 law blocked sustainable development goals for their provinces. The reform requires provincial leaders to verify that certain periglacial environments do not serve as strategic water reserves before permitting mining, aiming to balance resource use with environmental considerations.

Melted glacier water reduces drought impacts in arid provinces, where water scarcity already challenges daily life and agriculture. The reform could alter river basin flows, affecting homes and farms in areas dependent on these sources for drinking and irrigation. Governors supporting the change argued it promotes national economic growth without harming future generations, though critics like Rossi Serra pointed out that arid regions rely heavily on gradual thaws for consistent water flow.

Provinces such as Catamarca and Jujuy see the reform as a path to extract minerals without past restrictions, with backers stating it aligns with goals for sustainable development. The Senate approved the bill in February, making the lower house vote the final step in its passage. Residents in affected areas may now push for local assessments to ensure water reserves remain protected, directly influencing community access to essential resources.
