This article summarizes research completed to assess the risk of lightning-related injuries and fatalities in Canada. Although lightning mortality has declined significantly over the past century, it remains a common meteorological hazard that regularly kills and injures. Based on an analysis of media reports, vital statistics, hospital admission and emergency room visit records, and fire loss data, the authors estimate that on average about 9-10 lightning-related deaths and 92-164 injuries occur each year in Canada. The distribution of casualties reflects current provincial population and cloud-to-ground lightning densities. Consistent with similar studies in other developed nations, most lightning-related fatalities and injuries in Canada occur during the June-August summer season, coincident with peak lightning, and during the Thursday-Saturday period, most likely related to higher rates of participation in outdoor activities. The majority of victims are male, less than 46 years old, and engaged in outdoor recreational activities when injured or killed in a lightning incident. Media reports used in the study were found to underestimate both lightning mortality (36%) and morbidity (20-600%).
The scientifi c community and park professionals recognize that climate change could have a substantial impact on the natural landscape of mountain parks worldwide, with important implications for conservation policy and park planning. Little is known however about how tourists may respond to these projected environmental changes. To explore this question in the context of Canada's Rocky Mountain national parks, a visitor survey was administered (n = 809) in two national parks: Banff and Waterton Lakes. The environmental change scenarios constructed for the early and mid-decades of the 21st century were found to have minimal infl uence on intention to visit. The environmental change scenario for the latter decades, under a high emission climate change scenario, was found to have a negative effect on intention to visit, as 36% of respondents indicated they would visit the parks less often and 25% not at all. Visitors most likely to be negatively affected by climate-induced environmental change were nature-based tourists from overseas, motivated by the opportunity to view mountain landscapes and wildlife. The hitherto largely overlooked conceptual and methodological challenges of understanding how tourists may respond to multidecadal environmental changes induced by global climate change in any tourism setting is also discussed.
Urbanization and re‐urbanization continually alter spatial patterns of social disadvantage and hazard exposure, which in turn affect social vulnerability. The current study explores vulnerability to hazards in Greater Vancouver over a 15‐year period (1986 to 2001). Results illustrate how social disadvantage is multi‐dimensional and emerges from the social geography of a city. The study illustrates the speed with which both the structure and spatial patterns of social disadvantage can change in cities experiencing rapid growth or redevelopment. The study also suggests that Greater Vancouver does not display consistent patterns of minority‐ or income‐based environmental inequity in hazard exposure, which raises questions about the role of various policies in ameliorating vulnerability to natural and technological hazards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
