GIS & Local Food Practices

This paper combines GIS and socio-spacial analysis with different city components to view the movement of local food in Philadelphia. This study indicated only a very small portion of Philadelphia's food comes from local sources.
What local sources that do make it into the city, on average travel about 60 miles.  The authors geographically overlaid city data such as median income over the urban food system to get a better understanding of how social issues such as poverty affect the system.
Their findings indicate that farmers markets and locally sourced suppliers tend to target those with higher incomes.Those who reside in low-income areas are beginning to see an influx of locally grown foods in the form of community gardens.

  1. There is a lot of research about the overlaps of local food production and food stamps, and the effects of hunger and obesity, so it would be interesting to apply this research in that capacity.

  2. That is not something I would have initially thought of, but I am now wondering how the use of food stamps plays into the production and localities involved.

  3. I have discovered that this quite true when it comes to my hometown of Minneapolis.
