Diet-related chronic diseases are highly prevalent among indigenous populations in the Canadian Arctic. A community-based, multi-institutional nutritional and lifestyle intervention-Healthy Foods North-was implemented to improve food-related psychosocial factors and behaviors among Inuit and Inuvialuit in four intervention communities (with two comparison communities) in Nunavut and the Northwest Territories, Canada, in 2008. The 12-month program was developed from theory (social cognitive theory and social ecological models), formative research, and a community participatory process. It included an environmental component to increase healthy food availability in local stores and activities consisting of community-wide and point-of-purchase interactive educational taste tests and cooking demonstrations, media (e.g., radio ads, posters, shelf labels), and events held in multiple venues, including recreation centers and schools. The intervention was evaluated using pre- and postassessments with 246 adults from intervention and 133 from comparison communities (311 women, 68 men; mean age 42.4 years; 78.3% retention rate). Outcomes included psychosocial constructs (healthy eating knowledge, self-efficacy, and behavioral intentions), frequency of healthy and unhealthy food acquisition, healthiness of commonly used food preparation methods, and body mass index (kg/m2). After adjustment for demographic, socioeconomic status, and body mass index variables, respondents living in intervention communities showed significant improvements in food-related self-efficacy (β = 0.15, p =.003) and intentions (β = 0.16, p =.001) compared with comparison communities. More improvements from the intervention were seen in overweight, obese, and high socioeconomic status respondents. A community-based, multilevel intervention is an effective strategy to improve psychosocial factors for healthy nutritional behavior change to reduce chronic disease in indigenous Arctic populations. © 2012 Society for Public Health Education.

The construction of the White Pass & Yukon Route (WP&YR) railway in 1900 from Skagway Alaska to Whitehorse, Yukon brought the supply centres of Vancouver and Seattle, 1600 kilometres closer to the Klondike region of the Yukon. The previous river supply route to Dawson was 2400 kilometres long and started at St. Michael, Alaska, at the mouth of the Yukon River on the Bering Sea. With the construction of the railway to the head of navigable water on the Yukon River, the river supply route was reduced to an 800 kilometre trip down the Klondike River from Whitehorse to Dawson City. Sternwheelers became a vital part of Yukon transportation, and the Yukon River sternwheelers were designed to carry heavy cargoes downstream on a light draft and make the return trip upstream with lighter loads. The S.S. Klondike was one of these sternwheelers, originally built in Whitehorse, in 1929 by the British Yukon Navigation Company. With a cargo capacity 50 percent greater than other boats on the river at the time, it was the first sternwheeler on the Yukon River large enough to handle a cargo in excess of 272 tonnes (300 tons) without having to push a barge. Carrying general cargo and a few passengers, the S.S. Klondike would make the downstream run from Whitehorse to Dawson City - a distance of some 740 kilometres (460 mi.) in approximately 36 hours with one or two stops for wood. The upstream journey back to Whitehorse, would take four or five days and six wood-stops. The SS Klondike is now a National Historic Site of Canada.

Cumulative effects management requires understanding the environmental impacts of development and finding the right balance between social, economic, and environmental objectives. We explored the use of choice experiments to elicit preferences for competing social, economic, and ecological outcomes in order to rank land and resource development options. The experiments were applied in the Southeast Yukon, a remote and resource rich region in Northern Canada with a relatively large aboriginal population. The case study addresses two issues of concern in cumulative effects management: the willingness to discount future environmental costs for immediate development benefits, and the existence of limits of acceptable change for communities affected by development. These issues are thought to be particularly relevant for First Nations in Northern Canada where cultural identify is tied to the land and continuity of the community is an important value. We found that residents of the Southeast Yukon value benefits from both development and conservation and must make trade-offs between these competing objectives in evaluating land use scenarios. Based on the preference information we evaluated four land use scenarios. Conservation scenarios ranked higher than development scenarios, however, there was significant heterogeneity around preferences for conservation outcomes suggesting a low degree of consensus around this result. We also found that residents did not discount the future highlighting the importance of intergenerational equity in resource development decisions. We did not find evidence of development thresholds or limits of acceptable change. Interestingly we found no difference in preferences between the aboriginal and non-aboriginal populations. © 2012 by the author(s). Published here under license by the Resilience Alliance.

Conservation programs often manage populations indirectly through the landscapes in which they live. Empirically, linking reproductive success with landscape structure and anthropogenic change is a first step in understanding and managing the spatial mechanisms that affect reproduction, but this link is not sufficiently informed by data. Hierarchical multistate occupancy models can forge these links by estimating spatial patterns of reproductive success across landscapes. To illustrate, we surveyed the occurrence of grizzly bears (Ursus arctos) in the Canadian Rocky Mountains Alberta, Canada. We deployed camera traps for 6 weeks at 54 surveys sites in different types of land cover. We used hierarchical multistate occupancy models to estimate probability of detection, grizzly bear occupancy, and probability of reproductive success at each site. Grizzly bear occupancy varied among cover types and was greater in herbaceous alpine ecotones than in low-elevation wetlands or mid-elevation conifer forests. The conditional probability of reproductive success given grizzly bear occupancy was 30% (SE = 0.14). Grizzly bears with cubs had a higher probability of detection than grizzly bears without cubs, but sites were correctly classified as being occupied by breeding females 49% of the time based on raw data and thus would have been underestimated by half. Repeated surveys and multistate modeling reduced the probability of misclassifying sites occupied by breeders as unoccupied to <2%. The probability of breeding grizzly bear occupancy varied across the landscape. Those patches with highest probabilities of breeding occupancy-herbaceous alpine ecotones-were small and highly dispersed and are projected to shrink as treelines advance due to climate warming. Understanding spatial correlates in breeding distribution is a key requirement for species conservation in the face of climate change and can help identify priorities for landscape management and protection. © 2014 Society for Conservation Biology.

The Canadian province of Alberta is partnering with the world’s leading all-electric bus firm, BYD, for the development of “smarter, safer transit buses,” according to an email sent to CleanTechnica and EV Obsession. The new framework agreement seems to be a serious one, as it was actually signed in the presence of Canadian Prime Minister Justin Trudeau and Canadian Minister of International Trade Chrystia Freeland, while in Shanghai. “Alberta is making strides in clean technology development and is looking to be a leader in smart infrastructure and electric transportation systems. BYD is excited to leverage the province’s machine learning, advanced sensors, and software development expertise to build even smarter and safer zero-emission buses,” stated BYD Heavy Industries Vice President Ted Dowling. “Not only has BYD delivered more than 10,000 buses worldwide that have more than 250 million kilometers of in revenue service, but in head-to-head trials against diesel buses, our battery-electric buses have proven their reliability in even the coldest climates. BYD is proud of our record as a global leader in all-electric buses, and this partnership will support both smarter transit technology and high-tech skill creation for a greener future.” The email notes that BYD is bringing substantial electric bus expertise to the partnership, having been arguably the first to bring a long-range, all-electric transit bus to market (back in 2011). The BYD lineup now includes 7 different electric bus models, “ranging from a 23-foot coach to a 60-foot articulated transit bus,” BYD notes. Going on: “There are BYD battery-electric buses running on 6 continents that have together saved customers tens of millions of dollars in fuel and maintenance costs. BYD’s proprietary Iron-Phosphate (or ‘Fe’) Battery is the safest and longest lasting electric bus battery available on the market today. Not only is the battery fully recyclable and flame resistant, but BYD also offers a full 12-year battery warranty, the longest electric battery warranty available in the industry.” “We are very pleased to be partnering with BYD to promote the facilitation of collaborative research and development, and commercialization activities,” commented Deron Bilous, Minister of Economic Development and Trade with the Government of Alberta. “Collaboration with global firms like BYD support diversification of Alberta’s economy, high tech skill creation, and increased export of technology products and services.” Current plans call for initial program details to be hammered out between BYD, partner firms in Alberta’s tech industry, the Alberta Centre for Advanced MNT Products, the University of Alberta, and the University of Calgary, later this fall.
