Glacier retreat in the Peruvian Andes is altering mountain water systems, and in some catchments exposed rock and sediments are generating acid rock drainage (ARD) – a natural acidification process that can harm ecosystems and human health.

In response to this issue, the NexGLAS project – a GEO Mountains Small Grants 2024–2025 recipient – aimed to investigate the glacier–water–health nexus in farming communities of the Cordillera Blanca, focusing on the Negro River Catchment. An interdisciplinary team from PUCP and UPCH studied how long-term glacier loss influences water quality and downstream impacts. Methods included in-situ and remote sensing monitoring, mapping and modeling, and qualitative and participatory approaches with local communities.

In this closing event, the main results of the NexGLAS project on the socio-ecological impacts of acid rock drainage in the Negro River catchment (Huaraz, Peru) will be presented. The event will also showcase a new interactive web platform, and provide an opportunity to discuss the challenges associated with monitoring and the co-production of knowledge.
