Who’S Cooking Tonight? A Time-Use Study Of Coupled Adults In Toronto, Canada, Bochu Liu, Michael J. Widener, Lindsey G. Smith, Steven Farber, Dionne Gesink, Leia M. Minaker, Zachary Patterson, Kristian Larsen, Jason Gilliland

Geography & Environment Publications

Understanding how coupled adults arrange food-related labor in relation to their daily time allocation is of great importance because different arrangements may have implications for diet-related health and gender equity. Studies from the time-use perspective argue that daily activities such as work, caregiving, and non-food-related housework can potentially compete for time with foodwork. However, studies in this regard are mostly centered on individual-level analyses. They fail to consider cohabiting partners’ time spent on foodwork and non-food-related activities, a factor that could be helpful in explaining how coupled partners decide to allocate time to food activities. Using 108 daily time-use logs …

Parents’ Perceptions Of Their Children’S Physical Activity During The Covid-19 Pandemic, Emma Ostermeier, Patricia Tucker, Danielle Tobin, Andrew Clark, Jason Gilliland

Geography & Environment Publications

Background

COVID-19 has drastically changed the everyday lives of children, including limiting interactions with peers, loss of regularly organized activities, and closure of schools and recreational facilities. While COVID-19 protocols are in place to reduce viral transmission, they have affected children’s access to physical activity opportunities. The purpose of this study was to understand how COVID-19 has affected children’s engagement in physical activity and to identify strategies that can support children’s return to physical activity programming in public places.

Methods

Parents of past participants in the Grade 5 ACT-i-Pass Program in London, Ontario, Canada were invited to participate in a …

Intake Of Fruits, Vegetables, And Sugar-Sweetened Beverages Among A Sample Of Children In Rural Northern Ontario, Canada, Brenton L.G. Button, Louise W. Mceachern, Gina Martin, Jason A. Gilliland

Geography & Environment Publications

There is evidence to suggest that dietary intake of children differs by rural/urban place of residence: rural children may have a higher intake of foods high in fat and sugar than those living in urban environments. The aim of this study was to examine the intake of fruits and vegetables (FV) and the frequency of sugar-sweetened beverage (SSB) consumption, among a sample of rural children in Northern Ontario, Canada, in two different seasons. Sociodemographic factors and children’s FV and SSB intake were measured using two repeated cross-sectional surveys, and seasonal information was based on the month of data collection. Logistic …

Junk Food Accessibility After 10 Years Of A Restrictive Food Environment Zoning Policy Around Schools, Lindsey Soon, Jason Gilliland, Leia M. Minaker

Geography & Environment Publications

Zoning has been proposed as a way of reducing unhealthy food access for youth, but little research has evaluated outcomes of proposed or existing junk food bans, and even less research has considered equity implications of such zoning policies. In this simulation study, set in the Region of Waterloo, Ontario (Canada), we examined how secondary student access to fast food restaurants and convenience stores would change under such a policy over 10 years in a mid-sized Canadian municipality. Outcomes are presented by school-level advantage (derived from the proportion of students in equity-deserving subgroups: low income, students who speak English …

This study (i) investigates elementary school children’s knowledge about food and nutrition and (ii) identifies sociodemographic factors influencing children’s reported knowledge. Methods: In 2017–2019, a survey was administered to 2443 students (grades 5–8) at 60 schools across southwestern Ontario, Canada, and a parent survey was used to validate self-reported sociodemographics. Multiple regression was used to analyse children’s knowledge scores and related sociodemographic factors. A total knowledge score was calculated by summing correct responses derived from 46 individual questions in the student …

Rethinking Walkability And Developing A Conceptual Definition Of Active Living Environments To Guide Research And Practice, Melissa Tobin, Samantha Hajna, Kassia Orychock, Nancy Ross, Megan Devries, Paul J. Villeneuve, Lawrence D. Frank, Gavin R. Mccormack, Rania Wasfi, Madeleine Steinmetz-Wood, Jason Gilliland, Gillian L. Booth, Meghan Winters, Yan Kestens, Kevin Manaugh, Daniel Rainham, Lise Gauvin, Michael J. Widener, Nazeem Muhajarine, Hui Luan, Daniel Fuller

Geography & Environment Publications

Background

Walkability is a popular term used to describe aspects of the built and social environment that have important population-level impacts on physical activity, energy balance, and health. Although the term is widely used by researchers, practitioners, and the general public, and multiple operational definitions and walkability measurement tools exist, there are is no agreed-upon conceptual definition of walkability.

Method

To address this gap, researchers from Memorial University of Newfoundland hosted “The Future of Walkability Measures Workshop” in association with researchers from the Canadian Urban Environmental Health Research Consortium (CANUE) in November 2017. During the workshop, trainees, researchers, and practitioners …

School-Level Perspectives Of The Ontario Student Nutrition Program, Mariam R. Ismail, Jason A. Gilliland, June I. Matthews, Danielle S. Battram

Geography & Environment Publications

The purpose of this study was to assess the implementation of a school snack program for children in elementary schools. School-level program volunteers’ experiences were explored using semi-structured interviews. Fieldnotes were taken during on-site school visits. Quantitative data were collected through a General Information Form and Weekly Logbooks. Seven elementary schools in Southwestern Ontario were invited and agreed to participate. Interviews (n = 27) revealed that volunteers valued the program for its universality, the excitement it created, the opportunity for students to try new foods, and the social interactions that it generated. Challenges included the burden on snack volunteers to …

Parents’ Attitudes Regarding Their Children’S Play And Sport During Covid-19, Monika B. Szpunar, Leigh M. Vanderloo, Brianne A. Bruijns, Stephanie Truelove, Shauna M. Burke, Jason Gilliland, Jennifer D. Irwin, Patricia Tucker

Geography & Environment Publications

The COVID-19 pandemic and associated public health measures have interrupted the daily routines of parents and children. The purpose of this study was to explore parents’ attitudes regarding their children’s play/sport during COVID-19. A secondary objective was to explore the influence of parent demographics and parent-reported physical activity levels and risk tolerance on these attitudes. Ontario parents of children aged 12 and younger completed an online survey (August—December 2020) that assessed their attitudes (grouped by support, safety and socialization-related attitudes; n = 14 items) regarding their child(ren)’s play/sport, their physical activity levels (n = 2 items), and demographic details …

The Mobility Of Experiential Learning Pedagogy: Transferring Ideas And Practices From A Large- To A Small-Campus Setting, Roza Tchoukaleyska, Ken Carter, Emily Dluginski, Marilyn Forward, Andrew King, Olivia Leblanc, Christopher Ratcliffe

Geography & Environment Publications

In this article, we examine the development of a new, experiential learning human geography and planning course at a smaller campus in Newfoundland, Canada. Our interest is twofold: to consider how pedagogical approaches can be transferred between a large urban campus and a small-town location; and to examine the benefits and complications of such transfers through a reflective examination of the resulting experiential learning program. The article captures the experiences of students, faculty, and university engagement staff in the deployment of the course. From these perspectives, we situate the decision to transfer an existing program across universities, the nuances of …

Comparing Household And Individual Measures Of Access Through A Food Environment Lens: What Household Food Opportunities Are Missed When Measuring Access To Food Retail At The Individual Level?, Lindsey G. Smith, Michael J. Widener, Bochu Liu, Steven Farber, Leia M. Minaker, Zachary Patterson, Kristian Larsen, Jason Gilliland

Geography & Environment Publications

Geographers and public health researchers have long been interested in social, spatial, and economic factors that drive access and exposure to food retail. A growing body of evidence draws on mobility data to capture locations accessed by individuals beyond the home address. Given that food-related activities are shared by household members and often gendered, taking an individual-level approach might limit researchers’ ability to accurately describe access to food retail. Using data that includes Global Positioning System trajectories of forty-six adults from twenty-one households in Toronto, this study compares access to food retailers at the individual and household levels and evaluates …

Building Climate Resilient Communities: Living Within The Earth’S Carrying Capacity, Gordon Mcbean, Paul Kovacs, James Voogt, Greg Kopp, Sophie Guilbault

Geography & Environment Publications

This Knowledge Synthesis examines how Canadian communities can proactively advance climate resilience to effectively reduce the risk from climate change impacts.

Our synthesis reveals that some communities have prepared high level adaptation plans, but very few have a detailed implementation strategy with established funding frameworks. Most actions to build community resilience in Canada are unplanned and take place in recovery following an extreme loss event. Indigenous communities are at the forefront of climate change adaptation in Canada. Self-determination and adaptive capacity building through community-led risk assessments, planning, and disaster recovery organizations, while addressing the broader context of reconciliation gaps and …

"Anishinaabe Time": Temporalities And Impact Assessment In Pipeline Reviews, Sakihitowin Awasis

Geography & Environment Publications

Indigenous ways of living that embrace multiple temporalities have been largely supplanted by a single, linear colonial temporality. Drawing on theoretical insights from Indigenous geographies and political ecology, this article considers how pipeline reviews come into being through contested temporalities and how dominant modes of time dispossess Indigenous peoples of self-determination in energy decision-making. In particular, Anishinaabe clan governance – a form of kinship that provides both social identity and function based on relations to animal nations – is undermined in colonial decision-making processes. Through analysis of documents from Canada’s National Energy Board and interviews with Anishinaabe pipeline opponents, I …

Gwaabaw: Applying Anishinaabe Harvesting Protocols To Energy Governance, Sakihitowin Awasis

Geography & Environment Publications

Oil and gas extraction has transformed Anishinaabe society in ways that undermine the consensual, holistic, and egalitarian basis of natural law. To many Indigenous people, framing fossil fuels and other energy sources as “natural resources” does not accurately define energy projects or capture related risks. Some Anishinaabe pipeline opponents have suggested that traditional harvesting protocols–culturally embedded moral precepts that govern the gathering of food and medicinal plants–also be applied to activities that produce energy. This paper explores how this could be done, focusing on tar sands extraction and the Line 3 expansion plan. I begin by discussing Anishinaabe harvesting protocols, …

Soundscaping The Archives: Disrupting Boundaries Through Sensory Research, Kathryn Allyn, Roza Tchoukaleyska

Geography & Environment Publications

Through this paper, we seek to re-imagine and challenge the meaning of archival spaces. While archival spaces are repositories of information, they are also sites where cultural values and public memory are shaped, and forms of power enacted. Drawing on sensory ethnography research in the Le Corbusier archives in Paris, France, we consider how boundaries are disrupted through noise, echo, reverberations, buzzing, and other “sounds.” Our work is presented in two overlapping textures: a soundtrack, with recordings from the Le Corbusier archives; and the text written out below. Alongside tracing archival soundscapes, a secondary function of this paper is to …

Short Communication: Challenges And Applications Of Structure-From-Motion Photogrammetry In A Physical Model Of A Braided River, Peter Ashmore, Pauline Leduc, Sarah Peirce

Geography & Environment Publications

For extending the applications of structure-from-motion (SfM) photogrammetry in river flumes, we present the main challenges and methods used to collect a large dataset ( > 1000 digital elevation models, DEMs) of high-quality topographic data using close-range SfM photogrammetry. Automatic target detection, batch processing, and considerations for image quality were fundamental to the successful implementation of the SfM technique on such a large dataset, which was used primarily for capturing details of gravel-bed braided river morphodynamics and sedimentology. While the applications of close-range SfM photogrammetry are numerous, we include sample results from DEM differencing, which was used to quantify morphology change …

Conceptualizing Youth Participation In Children’S Health Research: Insights From A Youth-Driven Process For Developing A Youth Advisory Council, Mohammad El-Bagdady, Krishna Arunkumar, Drew Bowman, Stephanie Coen, Christina Ergler, Jason Gilliland, Ahad Mahmood, Suraj Paul

Geography & Environment Publications

Given the power asymmetries between adults and young people, youth involvement in research is often at risk of tokenism. While many disciplines have seen a shift from conducting research on youth to conducting research with and for youth, engaging children and teens in research remains fraught with conceptual, methodological, and practical challenges. Arnstein’s foundational Ladder of Participation has been adapted in novel ways in youth research, but in this paper, we present a new rendering: a ‘rope ladder.’ This concept came out of our youth-driven planning process to develop a Youth Advisory Council for the Human Environments Analysis Laboratory, an …

Rates Of Planimetric Change In A Proglacial Gravel-Bed Braided River: Field Measurement And Physical Modeling, Lara Middleton, Peter Ashmore, Pauline Leduc, Darren Sjogren

Geography & Environment Publications

Planimetric change was measured on daily hydrographs over two meltwater seasons using time-lapse images of the proglacial, gravel, braided, Sunwapta River, Canada. Significant planimetric change occurred on 10-15 days per year. Area of planimetric change correlated with peak and total daily meltwater hydrograph discharge. A clear threshold discharge can be identified below which no planform activity occurs, an intermediate range over which change occurs conditionally, and a peak flow range at which significant change always occurs. Field conditions were reproduced in a physical model in a laboratory flume. Photogrammetric DEMs of bed morphology and measurements of bedload output were made …

Evolution Of Grain Size Distributions And Bed Mobility During Hydrographs In Gravel-Bed Braided Rivers, Sarah Peirce, Peter Ashmore, Pauline Leduc

Geography & Environment Publications

Evolution of bed material mobility and bedload grain size distributions under a range of discharges is rarely observed in braiding in gravel-bed rivers. Yet, the changing of bedload grain size distributions with discharge is expected to be different from laterally stable, threshold, channels on which most gravel bedload theory and observation are based. Here, simultaneous observations of flow, bedload transport rate, and morphological change were made in a physical model of a gravel-bed braided river to document the evolution of grain size distributions and bed mobility over three experimental event hydrographs. Bedload transport rate and grain size distributions were measured …

The Variability In The Morphological Active Width: Results From Physical Models Of Gravel‐Bed Braided Rivers, Sarah Peirce, Pauline Leduc, Peter Ashmore

Geography & Environment Publications

The morphological active width, defined as the lateral extent of bed-material displacement over time, is a fundamental parameter in multi-threaded gravel-bed rivers, linking complex channel dynamics to bedload transport. Here, results are presented from 5 constant discharge experiments, and three event hydrographs, covering a range of flow strengths and channel configurations for which morphological change, bedload transport rates, and stream power were measured in a physical model. Changes in channel morphology were determined via differencing of photogrammetrically-derived digital elevation models (DEMs) of the model surface generated at regular intervals over the course of ~115 hours of experimental runs. Independent measures …

Expanding The "Active Layer", Peter Ashmore, Sarah Peirce, Pauline Leduc

Geography & Environment Publications

Church and Haschenburger (2017) make helpful distinctions around the issue of defining the active layer, with which we agree. We propose expanding discussion and definition of the ”active layer” in fluvial bedload transport to include the concept of the “morphological active layer”. This is particularly applicable to laterally unstable rivers (such as braided rivers) in which progressive morphological change over short time periods is the process by which much of the bedload transport occurs. The morphological active layer is also distinguished by variable lateral and longitudinal extent continuity over a range of flows and transport intensity. We suggest that the …

Technical Note: Ground-Based Remote Sensing Of A Mountain Stream: Measuring Stage And Water Width Using A Simple Time-Lapse Camera., Peter Ashmore, Pauline Leduc, Darren Sjogren

Geography & Environment Publications

Remote sensing applied to river monitoring adds complementary information useful for understanding the system behaviour. In this paper, we present a method for visual stage gauging and water surface width measurement using a ground-based time-lapse camera and a fully automatic image analysis algorithm for flow monitoring at a river cross section of a steep, bouldery channel. The remote stage measurement was coupled with a water level logger (pressure transducer) on site and shows that the image-based method gives a reliable estimate of the water height variation and daily flow record when validated against the pressure transducer (R = 0.91). …

Public Places And Empty Spaces: Dislocation, Urban Renewal And The Death Of A French Plaza, Roza Tchoukaleyska

Geography & Environment Publications

This article examines the dislocations produced when competing understandings of public space come into contact. Focusing on Montpellier, France, where an urban renewal program has seen portions of the city-centre renovated, the article considers the breaking apart of a North African commercial cluster under the guide of French heritage protection. Arguing that such action is tiedto municipal urban politics and wider trajectories that place diverse identities in a separate category, I trace the process through which a plaza encompassed in the urban renewal program has been labelled as “empty” and “dead” space. Suggesting that the relocation of a well-used outdoor …

Flume Tests On Fluvial Erosion Mechanisms In Till-Bed Channels, Peter Ashmore

Geography & Environment Publications

Semi-alluvial stream channels eroded into till and other glacial sediments are common in areas of extensive glacial deposition such as the Great Lakes region and northern interior plains of North America. The mechanics of erosion and erosional weakness of till results in the dominance of fluvial scour and spontaneous fracture at planes of weakness under shearing flow. There have been few controlled tests looking at erosional mechanisms and resistance of till in river channels. We subjected small blocks of till to unidirectional flows in a laboratory flume to measure the threshold shear stress for erosion and observed the erosion mechanics. …

Accuracy Evaluation Of The Canadian Openstreetmap Road Networks, Hongyu Zhang, Jacek Malczewski

Geography & Environment Publications

Volunteered geographic information (VGI) has been applied in many fields such as participatory planning, humanitarian relief and crisis management. One of the reasons for popularity of VGI is its cost-effectiveness. However, the coverage and accuracy of VGI cannot be guaranteed. The issue of geospatial data quality in the OpenStreetMap (OSM) project has become a trending research topic because of the large size of the dataset and the multiple channels of data access. This paper provides details on a national study of the Canadian OSM street network data for the assessment ofcompleteness, positional accuracy, attribute accuracy, semantic accuracy and lineage. The …

Morpho-Sedimentary Characteristics Of Proximal Gravel Braided River Deposits In A Froude-Scaled Physical Model, Peter Ashmore, Tobias Gardner, Pauline Leduc

Geography & Environment Publications

A Froude‐scaled physical model of a proximal gravel‐bed braided river was used to connect the river morphological characteristics, and sedimentary processes and forms, to deposit geometry. High resolution continuous three‐dimensional topographic data were acquired from sequential photogrammetric digital elevation models paired with grain‐size surface maps derived from image analysis of textural properties of the surface. From these data, the full three‐dimensional development of the braided river deposit and grain‐size sorting patterns was compiled over an experimental time period of 41 h during which the model river reworked a large portion of the braided channel. The minimum surface of the deposit …

Urbanizing Physical Geography, Peter Ashmore, Belinda Dodson

Geography & Environment Publications

The physical environment of cities and processes of urbanization have a long‐standing presence in the field of physical geography and can give physical geography a renewed relevance in urban sustainability and planning. Existing approaches in physical geography will be a valuable component of this work. New insights and understanding of urban environments may be gained by engaging with ideas of urban landscapes as socio‐natures; adopting critical, political, and reflexive modes of thought and practice; and thinking beyond the physical structures and spatial boundaries of the city to planetary urbanization. Thinking about urban environments in these ways also opens up possible …

Grain Sorting In The Morphological Active Layer Of A Braided River Physical Model., Pauline Leduc, Peter Ashmore, James T. Gardner

Geography & Environment Publications

A physical scale model of a gravel-bed braided river was used to measure vertical grain size sorting in the morphological active layer aggregated over the width of the river. This vertical sorting is important for analyzing braided river sedimentology, for numerical modeling of braided river morphodynamics, and for measuring and predicting bedload transport rate. We define the morphological active layer as the bed material between the maximum and minimum bed elevations at a point over extended time periods sufficient for braiding processes to rework the river bed. The vertical extent of the active layer was measured using 40 hourly high-resolution …

Transformative Geomorphic Research Using Laboratory Experimentation, Sean J. Bennett, Peter Ashmore, Cheryl Mckenna Neuman

Geography & Environment Publications

Laboratory experiments in geomorphology is the theme of the 46th annual Binghamton Geomorphology Symposium (BGS). While geomorphic research historically has been dominated by field-based endeavors, laboratory experimentation has emerged as an important methodological approach to study these phenomena, employed primarily to address issues related to scale and the analytical treatment of the geomorphic processes. It is contended here that geomorphic laboratory experiments have resulted in transformative research. Several examples drawn from the fluvial and aeolian research communities are offered as testament to this belief, and these select transformative endeavors often share very similar attributes. The 46th BGS will focus on …

Towards A Sociogeomorphology Of Rivers, Peter Ashmore

Geography & Environment Publications

While human impacts on rivers and other landforms have long been a component of geomorphic research, little of this work explicitly includes insights into human agency from social science or recognises that in many cases rivers can be considered to be hybrid coproductions or „socio-natures‟. A socio-geomorphic approach proposed here has parallels with some aspects of sociohydrology and can extend and enrich existing geomorphic explanations of the morphology of, for example, urban rivers by explicitly recognising and working with the coevolution of the human and natural systems. Examples from recent literature illustrate ways in which these relationships can be understood …

Perceptions And Experiences Of Environmental Health Risks Among New Mothers: A Qualitative Study In Ontario, Canada, Eric Crighton, C Brown, Jamie Baxter, L Lemyre, J R. Masuda, F Ursitti

Geography & Environment Publications

There is a growing awareness and concern in contemporary societies about potential health impacts of environmental contaminants on children. Mothers are traditionally more involved than other family members in managing family health and household decisions and thus targeted by public health campaigns to minimise risks. However little is known about how new mothers perceive and experience environmental health risks to their children. In 2010, we undertook a parallel case study using qualitative, in-depth interviews with new mothers and focus groups with public health key informants in two Public Health Units in Ontario Province, Canada. We found that the concern about …
