This book deals with international law in Antarctica and the Arctic. It reviews how each region is managed by the individual legal regimes, and how the special international laws developed specifically to deal with polar problems (for instance, protection of the environment) have contributed to the development of international law. It covers the legal issues concerning the geography and environment of the regions; the relevant aspects of the law of the sea; resource management; and environmental protection. The author reviews the international relations regime theory to analyse the development of the Polar regimes, and considers how the international relations necessary to deal with the unique problems caused by the polar environment and regional politics, has contributed to a greater understanding of international law.
