Challenges in Evaluating Mining Impacts in the Periglacial Environment of the South American Andes

摘要

The evaluation of construction related impacts in the arid South American Andes is challenging. The main issues concern: (a) definitions, terminology and theoretical framework, (b) heterogeneity of mountain periglacial environment and permafrost conditions; and (c) the hydrological role of permafrost and related landforms such as rock glaciers. These issues need to be resolved to ascertain scientifically-based environmental impact assessment in such environments, which help project proponents and stakeholders alike. This requires additional scientific studies that address potential impacts from construction activities in such environments and a joint international effort and initiatives for consensus-building on the topics of terminology, heterogeneity of mountain conditions and the hydrological role of permafrost landforms and the periglacial zone.
