Residents of San Juan province in western Argentina fear that prospective mining projects in the Andes will deplete and pollute scarce water supplies [1, 2].
The conflict pits the pursuit of critical minerals against the survival of local agriculture and ecosystems in a region facing a severe water crisis. Because mining operations can divert and contaminate water sources, local communities worry that industrial growth will permanently damage the province's ability to sustain its population [2, 4].
San Juan is currently experiencing a critical shortage of water driven by a combination of prolonged drought and the broader effects of climate change [1, 4]. Some reports describe the situation as a result of once-sparkling rivers shriveling due to drought, while others emphasize a persistent shortage tied to climatic shifts [1, 2].
For local producers, the stakes are immediate. Virginia de Valle, who manages a 16-hectare vineyard [3], said, "Without water, there would be no wine."
The vulnerability of the region's hydrology is underscored by broader environmental pressures across Argentina. The country's ice cover, which spans 8,484 square kilometers [5], serves as a vital reservoir for the Andes. Meanwhile, other parts of the country have faced extreme weather, such as the fires in Patagonia during the summer of 2025 that burned over 270,000 acres [6].
Local residents argue that the introduction of large-scale mining during this period of instability is a risk the province cannot afford. They said that the diversion of water to processing plants will leave farmers, and residents, without the resources necessary for basic survival and economic stability [2, 4].
“Without water, there would be no wine.”
This situation highlights a growing global tension between the 'green transition' and local environmental preservation. As Argentina seeks to capitalize on critical minerals required for global technology and energy shifts, it faces a domestic crisis where the industrialization of the Andes may jeopardize the water security of its agricultural heartlands.
