The Buenos Aires Environment Minister, Daniela Vilar, expressed her opposition to the project seeking to amend the Glacier Law. The initiative, with Senate approval, is progressing in the Chamber of Deputies.
In this context, the environmental debate gains prominence due to its impact on water access. Additionally, the legislative process includes public hearings with high citizen participation.
More than 27,000 people registered to express their views on the reform. Thus, the issue is solidified as one of the country’s most relevant environmental topics.
A key system for water balance
The current law, enacted in 2010, protects glaciers and periglacial environments. These ecosystems function as strategic reserves of fresh water.
Additionally, they regulate the flow of rivers during drought periods. According to specialists, about 70% of the country depends on these systems.
Therefore, their preservation is essential for multiple productive activities. Even in the province of Buenos Aires, without glaciers, the impact is indirect.
The case of the Colorado River illustrates this interjurisdictional connection. This watercourse crosses Mendoza, Neuquén, La Pampa, Río Negro, and Buenos Aires. In Buenos Aires territory, it supports irrigation systems in Villarino and Patagones.
Environmental risks under discussion
From the ecological perspective, the reform raises concerns about possible irreversible impacts. Among them, the loss of fresh water reserves is mentioned.
There are also warnings about the contamination of basins by extractive activities. Furthermore, it could increase water variability and the frequency of droughts.
Without active glaciers, water could concentrate in specific seasons. This would imply excesses in spring and shortages in summer.
Additionally, there are warnings about inequalities between provinces due to environmental competition. This phenomenon could lead to a progressive relaxation of regulations.
Proposed changes to the Glacier Law
The project promoted by the national government proposes to modify the protection limits. In this way, productive activities would be allowed in currently restricted areas.
Among them, mining and hydrocarbon ventures are included under certain conditions. Additionally, the reform seeks to redefine periglacial areas.
This could reduce the area protected by the current regulations. On the other hand, it is argued that the changes would improve predictability for investments.
However, environmental sectors warn about possible legal conflicts. In parallel, there are questions about compatibility with regulations such as the Escazú Agreement. Tensions with article 41 of the National Constitution are also pointed out.
Civic participation and future challenges
The legislative process includes public hearings with strong social interest. However, the limited number of planned speakers is questioned.
This could restrict the right to environmental participation. In turn, the discussion is linked to economic policies such as the promotion of extractive investments.
In this context, the role of resources like lithium and copper is highlighted. However, the challenge lies in balancing development and sustainability, which is why specialists propose strengthening the implementation of the current law.
Among the measures, improving monitoring and updating the glacier inventory are included. Thus, the debate raises a central question: how to ensure development without compromising water, a vital resource for present and future generations.
