This study is a direct result of the Committee’s previous study, Canadian Farmers at Risk.1 As part of that study, the Committee travelled to the Maritimes to hear from farmers about their concerns. Farmers repeatedly expressed apprehension about changes in climate and were unsure as to how they could cope with – or adapt to – apparently new climate scenarios. After identifying the leading researchers in the field of climate change and adaptation in Canada and abroad, the Committee heard from witnesses at the forefront in this area from universities, research centres, and governments across Canada as well as internationally. The Committee took a country-wide approach and actively sought the views of farmer organizations, rural associations, ecotourism groups, and environmental and conservation organizations from all regions of Canada. The Committee held hearings in Ottawa and travelled to Saskatchewan, Alberta, and British Columbia (see the
