“…Burgoine [52] underlines "the time consuming negotiations, possible expense and probable stress of acquiring foodscape data from a robust source". The validity of secondary sources of food-outlet data to describe foodscapes was tested in the United Kingdom [46,47,51], and in Denmark [49,50]. Lebel et al [48] perform a systematic review and meta-analysis of such studies, showing greater variability in validity estimates in studies conducted in the USA than in Canada, the United Kingdom and Denmark.…”

Foodscape: A scoping review and a research agenda for food security-related studies

Since 1995, the term 'foodscape', a contraction of food and landscape, has been used in various research addressing social and spatial disparities in public health and food systems. This article presents a scoping review of the literature examining how this term is employed and framed. We searched publications using the term foodscape in the Web of Science Core Collection, MEDLINE, and Scopus databases. Analyzing 140 publications, we highlight four approaches to the foodscape: (i) Spatial approaches use statistics and spatial analysis to characterize the diversity of urban foodscapes and their impacts on diet and health, at city or neighborhood scales. (ii) Social and cultural approaches at the same scales show that foodscapes are socially shaped and highlight structural inequalities by combining qualitative case studies and quantitative surveys of food procurement practices. (iii) Behavioral approaches generally focus on indoor micro-scales, showing how consumer perceptions of foodscapes explain and determine food behaviors and food education. (iv) Systemic approaches contest the global corporate food regime and promote local, ethical, and sustainable food networks. Thus, although spatial analysis was the first approach to foodscapes, sociocultural, behavioral and systemic approaches are becoming more common. In the spatial approach, the term 'foodscape' is synonymous with 'food environment'. In the three other approaches, 'foodscape' and 'food environment' are not synonymous. Scholars consider that the foodscape is not an environment external to individuals but a landscape including, perceived, and socially shaped by individuals and policies. They share a systemic way of thinking, considering culture and experience of food as key to improving our understanding of how food systems affect people. Foodscape studies principally address three issues: public health, social justice, and sustainability. The review concludes with a research agenda, arguing that people-based and place-based approaches need to be combined to tackle the complexity of the food-people-territory nexus.

“…Data on fast food outlets and supermarkets were retrieved from the national business register (CVR) and the national food safety and hygiene regulation register (Smiley). The spatial and semantic validity has been described in previous research [ 37 ]. A pre-classification method of the business type based on the outlets name was applied as described in [ 37 ].…”

Neighbourhoods are frequently used as a measure for individuals’ exposure to the food environment. However, the definitions of neighbourhoods fluctuate and have not been applied consistently in previous studies. Neighbourhoods defined from a single fixed location fail to capture people’s complete exposure in multiple locations, but measuring behaviour using traditional methods can be challenging. This study compares the traditional methods of measuring exposure to the food environment to methods that use data from GPS tracking. For each of the 187 participants, 11 different neighbourhoods were created in which the exposure to supermarkets and fast food outlets were measured. ANOVA, Tukey’s Honestly Significant Difference (HSD) test and t-tests were performed to compare the neighbourhoods. Significant differences were found between area sizes and the exposure to supermarkets and fast food outlets for different neighbourhood types. Second, significant differences in exposure to food outlets were found between the urban and rural neighbourhoods. Neighbourhoods are clearly a diffused and blurred concept that varies in meaning depending on each person’s perception and the conducted study. Complexity and heterogeneity of human mobility no longer appear to correspond to the use of residential neighbourhoods but rather emphasise the need for methods, concepts and measures of individual activity and exposure.

“…Moreover, suggested to combine at least two secondary databases to increase the accuracy of food store data, especially for supermarkets and grocery stores [30][31][32]. Thus, in the first step, the most resent two secondary databases (for year 2015) from InfoCanada Group and Enhanced Point of Estimate (EPOI) (by DMTI Spatial Inc.) [33] were considered for this study.…”

Abstract:The rate of food insecurity has increased tremendously over the past decade in Canada. This increase has been more pronounced in rural and remote areas especially among Aboriginal peoples. Substantial studies indicated that nearly half of the on-reserve Aboriginal households in British Columbia (BC) suffer from some degree of food insecurity. Despite the valuable research about obtaining traditional food, the issue of access to market food has been less discussed in the literature. The aim of this study was to assess the local food environment of on-reserve Aboriginal peoples by using a proximity-based approach tool in terms of access to healthy food stores such as supermarket and grocery stores. In the first stage, the addresses of all healthy food stores were geocoded into a map layer. Then the locations of Aboriginal reserves were geocoded to a separate map layer. In the second stage, using "Closest Facility Analysis" tool in ArcGIS Version 10.3, the distance based on a 15-minute driving time was measured from each reserve to the closest healthy food destination on CanMapRouteLogistics network. The results indicated that 25% of Aboriginal reserves did not have reasonable access to healthy food stores. We concluded that Aboriginal peoples in low access rural reserves with lower socioeconomic status are at potential risk of perpetuate food insecurity.
