Available for the first time in English, this collection is of particular significance in a world where global climate change and its impact on communities, flora, and fauna is changing the way we govern our lives. Presented in both contemporary and historical perspectives, Petersen's interviews of residents shed further light on what is referred to as "tradi-tional knowledge" and regarded by Greenlanders as most pertinent to their own lives. Included here are illustrations and photographs from Petersen's extensive collection. Reliable first hand accounts of these subjects in the arctic, over an extended time span, are rare. Local Knowledge is an invaluable research tool into the causes and effects of 20th century industrialization, and its effects of the land.
