Abstract

This article analyzes Argentina's Law 26.639 on Minimum Standards for the Protection of Glaciers and the Periglacial Environment as a landmark case of pioneering environmental legislation and a result of socio-ecological mobilization. Through a political ecology approach that incorporates ecological, cultural, and intergenerational justice dimensions, this study combines documentary analysis, jurisprudential review, and management experience to explore the implementation of this policy within the context of Argentine federalism. It highlights: 1. the role of the National Glacier Inventory as a scientific-legal tool; 2. the tensions between provincial autonomy and national standards; 3. resistance against regressive interpretations; and 4. the emergence of alliances between scientists, social movements, and state institutions. We argue that the law represents a significant advance in environmental governance by establishing universal protection for all ice bodies, regardless of their immediate economic value. The conclusions highlight lessons for Latin America regarding the articulation between scientific knowledge, environmental activism, and regulatory frameworks in contexts of intense land use pressure and accelerated climate change.
