Moerlein, B.A. Fairbanks, Alaska May 2012 Ill Abstract Arctic ecosystems are undergoing rapid changes as a result of global climate change, with significant implications for the livelihoods of Arctic peoples. In this thesis, I use ethnographic research methods to detail prominent environmental changes observed and experienced over the past few decades and to document the impact of these changes on subsistence fishing practices in the Inupiaq communities of Noatak and Selawik in northwestern Alaska. Using in-depth key informant interviews, participant observation, and cultural consensus analysis, I explore local knowledge and perceptions of climate change and other pronounced changes facing the communities of Noatak and Selawik. I find consistent agreement about a range of perceived environmental changes affecting subsistence fisheries in this region, including lower river water levels, decreasing abundances of particular fish species, increasingly unpredictable weather conditions, and increasing presence of beaver, which affect local waterways and fisheries. These observations of environmental changes are not perceived as isolated phenomena, but are experienced in the context of accompanying social changes that are continually reshaping rural Alaska communities and subsistence economies. Consequently, in order to properly assess and understand the impacts of climate change on the subsistence practices in Arctic communities, we must also consider the total environment of change that is dramatically shaping the relationship between people, communities, and their surrounding environments. iv Table of Contents Page Signature Page........................................................................................................................... i Title Page...................................................................................................................................ii Abstract .....................................................................................................................................iii Table of Contents .....................................................................................................................iv Acknowledgements...............................................................................................................viii Chapter 1 Introduction: Arctic climate change and research approach ............................... 1 1.0 Arctic climate change and implications for northern communities ................... 1 1.1 Statement of research need ................................................................................. 3 1.2 Research context.................................................................................................. 4 1.3 Research objectives ..............................................................................................4 1.4.
