    Peatland communities in western Canada have slowly developed over thousands of years with wildfires being a constant influence on these systems. As fires move through mature peatland communities, the aftermath is an open landscape where pioneer peatland species establish and develop. The open landscape supports the growth of successional species to create a mature forest, which is then ready for the fire interval cycle to continue. Fire cycles have been a constant on the landscape with little disruption; however, as climate change in western Canada has altered precipitation and temperature regimes, typical vegetation succession patterns that establish after peatland fires may be changing. The Chisholm fire of 2001 burned over 116,000 hectares of forest in northern Alberta, with most of the area being peatlands (treed fens). Vegetation surveys were completed throughout 2018 and 2019 within the burned peatlands of the Chisholm area and compared to an unburnt control area to identify species richness, diversity, composition and vegetation trends. I found, within the re-establishing peatland, a healthy, thriving and diverse community that is developing towards a community similar to the offsite mature treed fen. After almost 20 years of recovery, the affected vegetation community is dominated by peatland species. With temperatures and precipitation levels continually changing, the area is at a transition state in which the community may be maintained on the landscape or the area may experience a regime shift to a drier state.

    China’s rapid economic growth in the past four decades has led to serious negative impacts on ambient air quality. Studies identify volatile organic compounds (VOCs) as the major cause of smog, which harms both human health and the environment. Nevertheless, VOC control faces tremendous challenges, especially when small and medium-sized enterprises (SMEs) in the furniture sector that account for a large percentage of VOCs in China find current, on-the-market technologies impractical and costly. To alleviate this problem, SunHub Inc. proposed a comprehensive 4-stage solution for abating VOCs at all stages of the production process. My study uses action research to assess the sustainability of SunHub’s solution and finds that it is indeed sustainable. To reach this conclusion, I conduct a two-phase case study. The first phase reviews the literature to determine the appropriate sustainability indicators for assessment, while the second phase analyzes SunHub’s documents and email correspondence with stakeholders.

    Red Deer, Alberta hosted Canada’s largest amateur sporting event in February 2019, the Canada Winter Games (CWG). There is little research on sustainability on the scale of a national amateur sporting event or impacts within the host community. Therefore, the research questions asked: can the introduction of sustainability initiatives through a sporting event truly have a lasting impact on the future of sustainability practices in Red Deer? Pre- and post-Game interviews were conducted with the sustainability managers and individuals at organizations involved in planning the Games. The results highlight that local community members are instrumental in affecting change by setting goals and it is critical to engage in planning sustainable initiatives as early as possible. Hosting the Games served as a catalyst for a range of sustainability initiatives in the City of Red Deer, which suggests that sustainable practices are likely to grow in the community.

    In the past fifty years, various concepts have emerged that have the potential to assist societies in achieving greater sustainability. In this article I will briefly review the evolution of the bioregion and biosphere reserve concepts, look at definitional issues, at their similarities and differences, and at their relative strengths and weaknesses as vehicles for promoting the greater sustainability of human societies. https://viurrspace.ca/bitstream/handle/10613/5436/Bioregions.pdf?sequence=4

    Hope is often credited as an inspiration for action and, in difficult circumstances, a protection against despair. But ill-considered hope can be an unreliable helper. If people choose only to hope for a happy outcome, rather than acting in their own interest, they risk losing the opportunity to improve their situation. Putting faith in hope alone, they may also find that, after crossing a critical marker, hope’s protection evaporates, suddenly and at great emotional cost. In that context and in the face of the gathering threat of climate change, this thesis records the search for a strategy that is better than hope – more active, robust and resilient. The search, including interviews with five high-profile and highly accomplished exemplars, suggests there might be value in simply recognizing the full extent of the threat and then embracing action in pursuit of a goal that is worthy, irrespective of a hoped-for result.

    Several regulatory policies have been implemented in the past five years on methane mitigation and oil sands industry emission in Alberta, Canada; however, most effective technologies in methane reduction remain to be explored in the context of these new policies in the Alberta oil sands industry. The purpose of this research was to determine the most effective technologies, based on economic and environmental criteria, to mitigate methane emissions from Alberta’s upstream oil sands processes. This was achieved through qualitative analysis of current technologies, and the development and application of a qualitative risk analysis and quantitative cost-benefit analysis considering economic and environmental factors. I concluded that high risk technologies have the lowest ratio of cost to environmental benefit and suggest that more effective technologies incur a greater risk to the industry; conversely, precise emission inventories need to be completed in order to identify areas of high emissions in individual cases.

    Energy is the dominant climate change contributor accounting for around 60% of total global gas emissions. Given the growing concerns and complexities associated with climate change, most countries worldwide have committed to delivering clean energy. One way to attain this is to invest in energy-efficient technologies such as efficient light bulb technologies. This study’s question was; what determines households’ energy efficiency light bulb adoption in Kiwatule? The main objective of this study was to investigate the behaviour and attitudes of households adopting energy-efficient light bulbs in Kiwatule. The research findings indicated financial motivation as the major determinant of efficient light bulb adoption. To facilitate this, the study suggested that the Ugandan government enacts the current energy light bulb bill and also extends efficient light bulb subsidies to all households.

    Wastewater Treatment Plants (WWTPs) frequently use anaerobic digestion (AD) to break down organics to reduce the total volume of biosolids produced. As population increases, cost of biosolids disposal increases while regulatory limits tighten. Bioaugmentation is an innovative process that enhances the biological activity within AD systems to improve performance through the addition of biocatalytic compounds (BC). Currently there is a knowledge gap regarding how the routine use of BCs, containing a consortium of bacteria and enzymes, applied directly within the AD system can affect the system’s performance and its by-products (biogas and biosolids). This study reviews the impact of routine bioaugmentation applications using a commercial grade BC on an AD system. An analysis of two full-scale AD systems inoculated with said BC has been completed to determine impacts on biosolids, and biogas production. This study provides significant information substantiating the claim that bioaugmentation enhances AD performance and long-term economic viability.

    The purpose of this thesis is to understand the perspectives of the environment among Indo-Canadian, Sri Lankan-Canadian and Filipino-Canadian immigrant communities who reside in Surrey, British Columbia. Environmental perception has commonly been defined as awareness of, or feelings about, the environment, or “the way in which an individual perceives the environment; the process of evaluating and storing information received about the environment” (Oxford Reference, 2019). By identifying key stakeholders within these communities, I explored perspectives of environmentalism and concerns for the improvement of the health of the environment, through a series of open-ended semi-structured interviews. The participants in this research demonstrated a willingness to improve and protect the quality of the natural environment. In addition, they acknowledged their lack of awareness regarding consequences of environmentally harmful activities that were occurring during their childhood, adolescence and early adulthood. The findings help identify the issues that prevent inclusive environmentalism in Surrey in these targeted immigrant populations. They could also assist policy makers and environmental programs to implement more effective approaches for raising awareness and promoting more environmentalism among the three diasporas.

    As a consequence of climate change, many populations of sockeye salmon in the U. S. Pacific Northwest are now experiencing significantly warmer river conditions during their spawning migration from the ocean to their freshwater spawning grounds compared to the 30 year average. The Columbia River witnessed an extended heat wave in 2015 and low flows pushed water temperatures to 21° C, which ended up killing 90 percent of the adult sockeye salmon returning to spawn in their natal streams in the summer months. Fish passage delays at hydro-electric dams potentially compounded this effect. The purpose of this study was to determine if water temperatures had a delay effect on run-timing and potential returning sockeye salmon population mortality in the Snake River in the Columbia Basin. Run timing and delays in migration patterns were examined over the years 2014-2018 in order to notice any trends in migration patterns. Results indicated that, as water temperatures increased, so did the travel time of returning adult sockeye salmon migrating between Bonneville Dam and Lower Granite Dam. Increased water temperatures were associated with migration delays, increasing them by as much as ten days more than the average in some years. Qualitative observations of fish vigor on migrating fish through fish windows also yielded signs of fungal disease on a small number of sockeye salmon during warmer water temperature outbreaks.
