| Summary: | This dissertation addresses climate and coastal changes in three small communities across the Canadian Arctic. The most pressing physical hazards were observed in Tuktoyaktuk, Northwest Territories (NWT) where erosive storm action and floods act on low-lying thermokarst terrain and shoreline infrastructure. Sachs Harbour, NWT is also experiencing rapid coastal erosion and permafrost ablation, although risks are moderated by the greater elevation of the townsite. Relatively few physical hazards were identified in Gjoa Haven, Nunavut but a sudden reservoir failure above the townsite in 2005 highlighted latent risks in infrastructure engineered to suit former climatic norms. -- In concert with physical hazard evaluations, community assessments were undertaken which revealed a variety of factors conditioning changes at the local level. They exposed significant community adaptation challenges stemming from human resource, organizational and relational factors. This approach also contributed to a working understanding of the many cross-scale interactions that ongoing physical changes are precipitating, in tandem with globalizing economic and social influences, on northern populations. Rapid changes in ice-rich terrain have raised concerns in relation to traditional Inuit livelihoods, knowledge and practices, but significant implications for northern community governance must also be recognized. Resilience is rendered as a dynamic, composite property of communities. A basic analytical framework derived from resilience theory was developed and used in the three Things Change, We Change community-based adaptation case studies. Adjustments were made along the way to suit arising local circumstances, in keeping with an exercise of adaptive as well as adaptation planning. The process has highlighted a number of factors conditioning community responses to environmental changes: examples are outlined using the Four Dimensions of Community Resilience defined and presented in a variety of ways to enhance legibility. -- ... |
