Data scientists map the supply chains of every US city

No matter where you live in the United States, some food in your kitchen probably started its life in California's agricultural fields. How do you know? Vegetables, like every other product, follow a supply chain that moves them from where they're grown to where they're consumed. That supply chain can be tracked through data, and those data paint a picture of how food, water and energy move throughout the United States. The result shows that every corner of America is connected. FEWSION is a data fusion project developed by scientist Ben Ruddell of Northern Arizona University and colleagues. The project maps the food, energy and water supply chains for every community in the United States. The data were collected by hundreds of researchers at federal agencies and universities throughout the country, and, for the first time, have been placed into a searchable and visual form for anyone to use. The maps are available on the FEW-View website, enabling Gulf Coast residents to see how much their gas prices could be affected by a hurricane, or how much New Englanders should worry about water shortages. With FEWSION, people can map the sources of their community's grains, meat and other foodstuffs; crude oil, gasoline, natural gas and electricity; and water sources.
