The issue of urban liveability has been extensively debated by global agencies and scholars, as evidenced by the New Urban Agenda, in response to the impact of urbanisation. Urban liveability pertains to the ability of urban communities to achieve a high-quality living environment. While participatory planning is often presented as a means of empowering communities to attain better living conditions, it has presented challenges for decision-makers. Furthermore, dominant actors often influence participation processes, benefiting certain community segments. As a result, collaborative planning has emerged as an approach that seeks to address the interests of multiple urban factors by promoting consensus in decision-making. This paper aims to examine the collaborative planning methods that have been used in strategic planning that have empowered the community to participate in the planning process. Content analysis was employed as a research method to explore the empirical evidence of collaborative planning that has successfully empowered community participation in strategic planning and its impact on the liveability of metropolitan areas. Correspondingly, the Melbourne, Vancouver, and Helsinki case studies were selected based on five liveable city indices. This study's findings suggest a positive correlation between the implementation of collaborative planning by the selected metropolitan areas and their status as the most liveable cities. This paper contributes to the ongoing debate on the role of collaborative planning in promoting urban liveability. [ABSTRACT FROM AUTHOR]

The process of urbanization resulting from population growth is causing a transformation of natural landscapes into built environments, and contributing to a significant rise in air and surface temperatures in urban areas, resulting in what is known as the urban heat island (UHI). Ignoring the UHI effect and use of weather data from open fields and airport locations for energy and thermal comfort analysis can lead to over- and underestimation of heating and cooling loads, improper sizing of equipment, inefficiencies in the mechanical systems operation, and occupants' thermal discomfort. There is a need for computationally efficient urban canopy temperature prediction models that account for the urban morphology and characteristics of the study area. This paper presents the development and application of an artificial neural network (ANN)-based method for generating hourly urban canopy temperature and local wind speed for energy simulation. It was used to predict the urban canopy temperature of a neighborhood in downtown Vancouver and the resulting building energy consumption and indoor temperature in a typical building in the area. The results showed that the UHI effect increased the total cooling energy demand by 23% and decreased the total heating energy consumption by 29%, resulting in an overall negative effect on the total energy demand of the building, which was 18% higher in the urban area. The UHI effect also increased the number of hours of indoor temperature above the cooling set point by 7.6%. The methodology can be applied to determine the urban canopy temperature of neighborhoods in different climate zones and determine the varying urban heat island effects associated with the locations.

Background: The COVID-19 pandemic had a disproportionate impact on the health and wellbeing of people who use drugs (PWUD) in Canada. However less is known about jurisdictional commonalities and differences in COVID-19 exposure and impacts of pandemic-related restrictions on competing health and social risks among PWUD living in large urban centres. Methods: Between May 2020 and March 2021, leveraging infrastructure from ongoing cohorts of PWUD, we surveyed 1,025 participants from Vancouver (n = 640), Toronto (n = 158), and Montreal (n = 227), Canada to describe the impacts of pandemic-related restrictions on basic, health, and harm reduction needs. Results: Among participants, awareness of COVID-19 protective measures was high; however, between 10 and 24% of participants in each city-specific sample reported being unable to self-isolate. Overall, 3–19% of participants reported experiencing homelessness after the onset of the pandemic, while 20–41% reported that they went hungry more often than usual. Furthermore, 8–33% of participants reported experiencing an overdose during the pandemic, though most indicated no change in overdose frequency compared the pre-pandemic period. Most participants receiving opioid agonist therapy in the past six months reported treatment continuity during the pandemic (87–93%), however, 32% and 22% of participants in Toronto and Montreal reported missing doses due to service disruptions. There were some reports of difficulty accessing supervised consumption sites in all three sites, and drug checking services in Vancouver. Conclusion: Findings suggest PWUD in Canada experienced difficulties meeting essential needs and accessing some harm reduction services during the COVID-19 pandemic. These findings can inform preparedness planning for future public health emergencies. [ABSTRACT FROM AUTHOR]

Rats are an important issue in cities globally. Despite their ubiquity, perceptions and concerns about rats vary with circumstance and the context in which a person interacts with them. Municipal rat management programs are a service to communities and therefore must be responsive to the varied concerns of their residents. Understanding why communities are concerned about rats can help inform rat management programs to meet the specific needs of their residents. The objective of this study was to identify why the residents of Vancouver, Canada care about rats and what they want done to address them. To do this, we qualitatively analyzed 6,158 resident complaints about rats made to the city's municipal government between January 2014 and May 2020. Using a qualitative descriptive coding process, we found that rats were a priority in a minority of cases. In general, people were more concerned about broader community issues, such as neighborhood disorder, of which rats were one part. Complaints tended to be made when problems were highly visible, nearby, and when the complainant wanted the city to take action to alleviate this issue, particularly when they were in and around their living spaces. The rates of complaints were highest in the most economically and socially deprived neighborhoods and lowest in the most privileged neighbourhoods. We synthesize this information with a view towards understanding how to develop objectives and actions for municipal management strategies that are grounded in community concerns.

• Assessment framework reveals progress in climate action planning in BC, Canada. • City differences clear: Victoria and Vancouver ahead of Surrey in sustainable paths. • Partnerships have been critical for supporting engagement in climate action. • Conditioning cities to report climate action progress has set a successful standard. • Feedback through self-assessment needed to identify most effective climate actions. To transition to a more sustainable and low-carbon economy, a series of local governments in British Columbia, Canada, are implementing climate action and innovation. This is largely in response to a need for societal changes in current development paths. However, there has been a lack of studies assessing the effectiveness of these actions and whether these municipalities are on track to meet their targets. This paper tests a newly developed assessment framework to evaluate local government actions and to better understand city-wide community development paths in three major cities in British Columbia—Vancouver, Victoria and Surrey. This assessment reveals notable progress in their transitions to sustainable pathways in areas such as agenda setting and strategy, plan formulation and implementation, and these sometimes result in transformative actions. Nonetheless, a gap between these actions and their performance reveals that local governments from this study are failing to properly address the current climate emergency. In particular, the municipalities lack processes for evaluating their progress in changing their current paths. This reduces their capacity to identify best practices to improve the effectiveness of climate actions and also hinders their ability to act on feedback and make adjustments to meet their stated goals and targets.

Introduction: Sex differences exist in children’s obesity rates, dietary patterns and television viewing. Television continues to be a source of unhealthy food advertising exposure to children in Canada. Our objective was to examine sex differences in food advertising exposure in children aged 2 to 17 years across four Canadian Englishlanguage markets. Methods: We licensed 24-hour television advertising data from the company Numerator for January through December 2019, in four cities (Vancouver, Calgary, Montréal and Toronto) across Canada. Child food advertising exposure overall, by food category, television station, Health Canada’s proposed nutrient profiling model, and marketing techniques were examined on the 10 most popular television stations among children and compared by sex. Advertising exposure was estimated using gross rating points, and sex differences were described using relative and absolute differences. Results: Both male and female children were exposed to an elevated level of unhealthy food advertising and a plethora of marketing techniques across all four cities. Differences between sexes were evident between and within cities. Compared to females, males in Vancouver and Montréal viewed respectively 24.7% and 24.0% more unhealthy food ads/person/year and were exposed to 90.2 and 133.4 more calls to action, 93.3 and 97.8 more health appeals, and 88.4 and 81.0 more products that appeal to children. Conclusion: Television is a significant source of children’s exposure to food advertising, with clear sex differences. Policy makers need to consider sex when developing food advertising restrictions and monitoring efforts. [ABSTRACT FROM AUTHOR]

A method for directly measuring carbon dioxide (CO2) emissions using a mobile sensor network in cities at fine spatial resolution was developed and tested. First, a compact, mobile system was built using an infrared gas analyzer combined with open-source hardware to control, georeference, and log measurements of CO2 mixing ratios on vehicles (car, bicycles). Second, two measurement campaigns, one in summer and one in winter (heating season) were carried out. Five mobile sensors were deployed within a 1 x 12:7 km transect across the city of Vancouver, BC, Canada. The sensors were operated for 3.5 h on pre-defined routes to map CO2 mixing ratios at street level, which were then averaged to 100 x 100m grid cells. The averaged CO2 mixing ratios of all grids in the study area were 417.9 ppm in summer and 442.5 ppm in winter. In both campaigns, mixing ratios were highest in the grid cells of the downtown core and along arterial roads and lowest in parks and well vegetated residential areas. Third, an aerodynamic resistance approach to calculating emissions was used to derive CO2 emissions from the gridded CO2 mixing ratio measurements in conjunction with mixing ratios and fluxes collected from a 28m tall eddycovariance tower located within the study area. These measured emissions showed a range of -12 to 226CO2 h-1 h-1 in summer and of -14 to 163 kgCO2 h-1 h-1 in winter, with an average of 35.1 kgCO2 h-1 h-1 (summer) and 25.9 kgCO2 h-1 h-1 (winter). Fourth, an independent emissions inventory was developed for the study area using buildings energy simulations from a previous study and routinely available traffic counts. The emissions inventory for the same area averaged to 22.06 kgCO2 h-1 h-1 (summer) and 28.76 kgCO2 h-1 h-1 (winter) and was used to compare against the measured emissions from the mobile sensor network. The comparison on a grid-by-grid basis showed linearity between CO2 mixing ratios and the emissions inventory (R² = 0:53 in summer and R² = 0:47 in winter). Also, 87% (summer) and 94% (winter) of measured grid cells show a difference within ±1 order of magnitude, and 49% (summer) and 69% (winter) show an error of less than a factor 2. Although associated with considerable errors at the individual grid cell level, the study demonstrates a promising method of using a network of mobile sensors and an aerodynamic resistance approach to rapidly map greenhouse gases at high spatial resolution across cities. The method could be improved by longer measurements and a refined calculation of the aerodynamic resistance. [ABSTRACT FROM AUTHOR]

This article discusses aboriginal language revitalization and education in urban areas. The author discusses various challenges facing language workers and learners in cities, including the perception that urban lifestyle and aboriginal identity are not compatible, linguistic and cultural diversity among urban aboriginal people, and issues surrounding urban residents' connections to the land. It is suggested that language workers and learners can form homeland-urban partnerships and bring language into previously existing forms of urban cultural expression. Details related to qualitative research on urban language revitalization in Vancouver, British Columbia and Coast Salish territories are presented. Popular stereotypes surrounding urban aboriginal peoples are also discussed.
