This book deals with the transformation of the Arctic from an isolated or a distant region to a member of the global community, vulnerable to global changes, and an area frequently in the very center of the world’s attention. Increased global interest is a potential source of tensions between the need for exploration or exploitation, and the requirements of protection. This context calls for new data, knowledge and information vital for a better understanding of interactions between different systems, as well as developing awareness about the current and potential changes in the future. The objective of the book is to help develop a strategy of adaptation to climate change based on the knowledge and experience of the extremely effective mechanisms which for centuries made survival possible in this region.
