The Argentine Chamber of Deputies is set to debate a proposed reform to the Glacier Law on April 8, following approval in committee. The national government aims for a legislative victory that could restore its political momentum, with the discussion focused on redefining which areas should be protected and granting more decision-making power to mining provinces.
The proposed changes to Law 26.639 introduce structural modifications in environmental protection. The most debated aspect is the redefinition of Article 1, which would limit protection exclusively to glaciers and landforms with proven water-related functions. According to the draft prepared by the Consejo de Mayo, each province’s environmental authority would verify whether an area serves as a water reserve or recharge basin.
Key points of the project include subordinating application of the law to Article 41 of Argentina’s National Constitution, supporting rational resource use; empowering provincial governments with verification duties; and applying restrictions on mining and hydrocarbons only in areas identified as having hydrological value by local authorities. Provinces would also determine if an industrial project causes significant alteration that could prohibit or allow such activities.
While supporters believe they have between 135 and 140 votes needed for passage, opposition parties such as Unión por la Patria plan strong resistance. They are expected to attempt delaying tactics during debate and may push for a motion affirming Argentina’s neutrality regarding conflicts involving the United States, Israel, and Iran—challenging current foreign policy alignment.
The reform also changes responsibilities for Ianigla (the Argentine Institute of Snow Research, Glaciology and Environmental Sciences), which will remain responsible for maintaining the National Inventory but will now rely on technical information from provinces. Government officials argue that after fifteen years under current law, many landforms’ real hydrological utility remains undetermined.
