NEW DATA: Land Preservation, Farm, Health, and Farmers Market Data. Plus updates to Baltimore Food History Map and Food: An Atlas!


Happy New Year!

New data added to the map:

  • Land Preservation layers – including protected lands and Rural Legacy lands. Specifically, the protected lands cover Maryland Agricultural Land Preservation Foundation (MALPF) easements, Department of Natural Resources (DNR) public lands and protected open space, and Maryland Environmental Trust (MET) easements. For Rural Legacy lands, we include both the properties purchased as well as lands designated for future purchase under the program.
  • Large-scale livestock farms – In our efforts to include more specific information about farms in Maryland, we are adding new categories of farms as they are available. With these updates, we are including those large-scale livestock farms that qualify by law as Concentrated Animal Feeding Operations (or CAFOs) or Maryland Animal Feeding Operations (MAFOs).
  • Health Data – We are pleased to now include the 2011 Obesity and Diabetes incidence rates, collected through the Behavioral Risk Factor Surveillance Survey (BRFSS). This national survey takes an annual sample of health and behaviors, some related to food consumption.
  • Farmers Markets – Thanks to Amy Crone at the Maryland Department of Agriculture, we have updated our farmers markets list for the whole state. Each site now includes information about the number of vendors, whether Farmers Market Nutrition Program (FMNP) and Fruit and Vegetable Coupons (FVC) are accepted and whether Supplemental Nutrition Assistance Program (SNAP, formerly known as Food Stamps) are accepted .

All of these new data layers are further defined in the "Glossary" in the "About the Map" section.

Updates to two of our Special Projects:

  • Baltimore Food History Map – Thanks to our partners at the Baltimore Museum of Industry, Collections Manager Catherine Scott Dunkes and intern Zack Wellington, we have added a number of new sites to this interactive time-scale map as well as historical photos which will show up in the info boxes. It is great to work with the Museum of Industry, and be able to tap into their wealth of knowledge on food processing and distribution in Baltimore. You can go directly to this map by clicking here.
  • Food: An Atlas – As mentioned in the previous newsletter, we are contributors to this "cooperatively-created, crowd-sourced and crowd-funded project of guerrilla cartography and publishing." The Atlas has now gone to press! We expect to have a copy of the printed Atlas in the CLF office by mid-February. In addition, the two maps we submitted are now online on our special projects page for you to view. One of the maps shows Baltimore City Food Swamps, while the other is a map of livestock production and slaughter capacity in Maryland. There is a website in the works to house all of the Atlas maps, hopefully to debut later this spring. We'll keep you posted.
