Mining, energy and infrastructure sectors in the circum-Arctic region are subject to extreme challenges and unlimited opportunities. This region has great natural resource potential with energy, mining and infrastructure development being the largest private sector contributors to economies. Adaptations to climate and other global environmental changes is occurring in the energy, mining and infrastructure sector by owners, operators, utilities and businesses in cooperation with governments, academic institutions, northern communities, and non-governmental organizations. This paper will discuss risk assessments, adaptation opportunities, the development of best practices and resiliency between these private and public actors.See Arctic Resource Development and Climate Impacts, Adaptation, and Mitigation project at http://www.arctic.ucalgary.ca/research for further information on the background research for this paper.
