Join us on your lunch break at Virtual 4TH SPACE over six days in July to hear from Concordia students and professors as they discuss their research on sustainability in general and the climate emergency in particular.
Originally scheduled as part of the now postponed cross-disciplinary conference Sustainability and the Climate Crisis, each of these six talks will highlight the varied research Concordians are currently undertaking to tackle the unfolding environmental emergency.
Rapid urban development in many countries worldwide has become a controversial issue due to its many negative effects. In Canadian metropolitan areas, built-up areas have increased by 157% between 1971 and 2011. Urban sprawl refers to dispersed, low-density development and research is urgently needed about patterns of urban sprawl in the past and in the present. This project assesses temporal changes in urban sprawl across all census metropolitan areas (CMAs) in Canada from 1991 to 2011 using the Urban Sprawl Metrics (USM) Toolset. It measures the metric of Weighted Urban Proliferation (WUP) and its three components: percentage of built-up area in the landscape (PBA), the dispersion of built-up area (DIS), and land uptake per person (LUP). The value of WUP answers the question of how strongly the landscape within the boundaries of the CMA is sprawled per km2. We also present Weighted Sprawl per Capita (WSPC), which answers the question of how much on average each inhabitant or workplace contributes to urban sprawl in a CMA. For example, in 2011, Saint John scored highest for WSPC (70.5 kUPU/(inhab. or job)), followed by Thunder Bay (61.5 kUPU/(inhab. or job)) and Greater Sudbury (59.7 kUPU/(inhab. or job)). The lowest values of WSPC were observed in Toronoto (13 kUPU/(inhab. or job)), Montreal (14.1 kUPU/(inhab. or job)), Vancouver (16 kUPU/(inhab. or job)), and Calgary (20.3 kUPU/(inhab. or job)). In addition, we compare CMAs in which the increase in urban sprawl has accelerated to those in which the increase has slowed down. Potential causes of these differences are discussed. The results are valuable for future urban and regional land use planning, such as the protection of agricultural soils, and for environmental monitoring.
