This study takes place in Tucson, Arizona, and focuses on the constraints of accessibility to a farmers’ market. Consumers who prefer healthy and environmentally friendly food have certain struggles that are not experienced with general grocery stores, such as limited hours of service and practical locations.
Figure 1 displays the distribution of population based on living location and what time of day that they work. The spatial distribution of city population varies with the time
of a day
Figure 3 illustrates the number of potential customers for each market within Tucson. There is a large area within the city limits that does not have a famers’ market within 8 miles. To maximize accessibility to all people, travel distance needs to be taken into account.

It would be awesome if GIS could be applied in order to explain the distribution of farmers market products to larger grocery stores as this could be a follow up/similar study to this one
ReplyDeleteI wonder if GIS could contribute to any studies that acknowledge the racial disparities in access to farmers markets. Are minorities disproportionately affected by lack of access to organic food?
ReplyDeleteOne of my posts was about a similar article that highlighted more the impact of distance as a factor of accessibility on local food. I would be especially curious in relation to Fig. 3 where they got the numbers on the potential consumers. Are those people who would walk, drive, bike, etc. to the market? And how can we tell if those people have those capabilities. I think this study could be expanded in very interesting ways.
