The National Good Food Network (US) has posted a set of useful new resources, including a Food Hub Benchmarking Study (pdf 236 kB), and Food Hubs: Solving Local – Small-Farm Aggregators Scale Up With Larger Buyers (pdf 2.2mB), both March 2014.
The NGFN website also has links to the complete set of video, audio and text resources from NGFN Food Hub Collaboration Spring 2014 Conference, held in Raleigh, NC from March 26-28, 2014.
