Svalbard's cultural heritage sites are important remnants of an international history in the High North. Cultural heritage in the Arctic is being impacted by climate and environmental change as well as increased human activity. Tourism is a potential cause of transformation in cultural heritage sites, such as increased wear and tear, creation of paths and traces as people walk through cultural environments. Cultural heritage management is therefore an increasingly challenging endeavor as management authorities must take under consideration multiple impacts and threats to cultural heritage sites in a changing environment. Based on research conducted in Svalbard from 2014 to 2016 on methods for long-term systematic cultural heritage monitoring, this paper will discuss dilemmas for a sustainable use and management of vulnerable cultural heritage sites in the Arctic.
