Capturing urban activities and environment across time scales: Object detection and time-series analysis of 6.8 million images in Accra, Ghana
Cities have complex dynamics on timescales from hourly and daily changes to monthly shifts and annual trends. We used time-lapsed street-view imagery (SVI) to capture and analyse temporal trends of urban environmental features in Accra, Ghana. We collected a novel dataset of 6.8 million street-view images (SVI) at five-minute intervals over five years at ten representative locations in Accra, Ghana. We used a fine-tuned YOLOv7 object detection mo…
Development and application of a geospatial index of urban playability for young children
Playing outdoors supports young children's physical, cognitive and social-emotional health and development. However, urban environments may limit children's outdoor play. We developed an evidence-based index to evaluate neighbourhood supportiveness for young children's outdoor free play, and applied it across 35 Canadian cities. From an evidence-based, theoretical framework for neighbourhood playability among children, 2–6 years, we identified fi…
Priority climate and health modelling needs
Climate and health modelling is necessary for improving understanding of the current and future distribution and timing of climate-related health risks. However, underinvestment in this area has limited the understanding required to inform policies that enable multisectoral interventions to safeguard health. We synthesised insights from a survey of 65 global climate and health modelling experts and 36 participants in a hybrid meeting to identify …

Inequalities in urban air pollution in sub-Saharan Africa: An empirical modeling of ambient NO and NO 2 concentrations in Accra, Ghana
Road traffic has become the leading source of air pollution in fast-growing sub-Saharan African cities. Yet, there is a dearth of robust city-wide data for understanding space-time variations and inequalities in combustion related emissions and exposures. We combined nitrogen dioxide (NO 2 ) and nitric oxide (NO) measurement data from 134 locations in the Greater Accra Metropolitan Area (GAMA), with geographical, meteorological, and population fa…
HealthyPlan.City: A Web Tool to Support Urban Environmental Equity and Public Health in Canadian Communities
Urban environmental factors such as air quality, heat islands, and access to greenspaces and community amenities impact public health. Some vulnerable populations such as low-income groups, children, older adults, new immigrants, and visible minorities live in areas with fewer beneficial conditions, and therefore, face greater health risks. Planning and advocating for equitable healthy urban environments requires systematic analysis of reliable s…
