Kremer and DeLiberty, the authors of this study, write that, "despite the centrality of geography of place in the study and practice of local food systems, methods of geographical analysis examining local food systems are just beginning to develop," providing a platform to analyze an area's potential for food production (Kremer & DeLiberty). The current system of industrial-scale food production, including Concentrated Animal Feedlot Operations (CAFOs), is incredible problematic. This type of food production largely contributes to deforestation, degradation of croplands, loss of biodiversity, and water, soil, and air pollution (Kremer & DeLiberty).
Kremer and DeLiberty acknowledge that
"Despite the centrality of geographical issues pertaining to local
food systems, few studies explore spatial analysis techniques for
the study of local food systems. Simple mapping tools are often
used by local food advocates. In food justice and
food access research, spatial analysis tools such as buffer distances
and service zone analysis are often used (see Russell & Heidcamp
and Eckert & Shetty in this volume)."
However, they continue on to argue that "a geospatial database is an
essential component in the understanding, development and
evaluation of local food systems" (Kreme & DeLiberty).
