Spring NEARC 2012

Graham Jeffries, Tufts University, Friedman School of Nutrition:

Eating “locally” has adsorbed to popular understanding of sustainable living, but the notion that “local is best” goes largely untested in much dialog at the intersection of food, environment, and social justice. In this presentation I show how spatial analysis tools are used to tease out the geographic intricacy of connecting balanced diets and biophysical resources in re-scaled “foodsheds” across the United States. The central inquiries of this presentation are, “what foodshed size could produce enough food for all of its residents?” and “how does the ‘optimum’ size vary across the US?”. I demonstrate how Python scripting and parallel processing are used to complete highly iterative network-based foodshed analyses. The novel “comparative foodshed analysis” approach demonstrates that there may be many more than 100 food miles between you and a resilient, just food system.
