🧊💧 A GEO Mountains-supported project in Peru's Cordillera Blanca is helping uncover a lesser-known climate risk: declining water quality linked to glacier retreat and acid rock drainage.
New research from the NexGLAS project found:
💧 Several glacier-fed catchments showed increasing acidity and poorer water quality
🌾 Shifts in local livelihoods away from traditional crop farming
🏥 Community concerns about water quality and associated health impacts
Importantly, the project combined satellite monitoring, hydrological research, and participatory approaches to better understand these interconnected challenges and identify locally relevant adaptation pathways.
The findings highlight the need to view glacier retreat not only as a cryosphere issue, but as a broader challenge for water security, governance, and human well-being in mountain regions.
