AbstractAs a contribution to the Nunavut Climate Change Adaptation Plan, a multidisciplinary project is assessing climate-change impacts and fostering adaptation planning initiatives across Nunavut in the Canadian Arctic. Residents of Arctic coastal communities are increasingly aware of climate change and impacts on safety and security. A compilation of community research needs in relation to climate-change impacts and adaptation has been published by the Nunavut Research Institute. This collection of observations derived from Inuit Qaujimajatuqanginnut (IQ) traditional knowledge highlighted concerns related to rising sea levels and coastal hazards. Risks to homes were
specifically highlighted in Qikiqtarjuaq and Hall Beach. Increased shore erosion has threatened properties along
part of the Hall Beach waterfront for a number of years. IQ
and data from ice-thickness measurements indicate that the date of freeze-up has been delayed by more than five weeks over 45 years (1959-2003). Given that freeze-up occurs during the autumn storm season, it is evident that more storms will now coincide with open water and that this will result in more wave action at Hall Beach. Shoreline changes over 50 years have been documented using digital photo- grammetry with airphotos every 10 years from 1957 to
1997, high-resolution satellite imagery from 2004,
and on-site shoreline surveys in 2007. The project is continuing with an analysis of ice extent and open-water fetch in Foxe Basin, winds at Hall Beach, wave conditions and sediment transport during autumn storms. The active involvement of residents through the Hall Beach Climate Change Adaptation Committee is a key enabling factor in this pilot project. The integration of traditional knowledge and scientific data provides a sound foundation of community awareness and understanding of risks to serve as a basis for adaptation decisions and actions. Under the Nunavut Climate Change Adaptation Plan, the intent is to extend this model to other communities across Nunavut.
