The following videos are segments on beginning farmers from the program Market to Market from Iowa Public Television. They reference Iowa State University's Beginning Farmer Center, Farm On, California Farm Link, California Coastal Rural Development Coalition, USDA Loan Programs, and the importance and potential for building relationships outside traditional family succession. They talk about the difficulty of getting started, and the potential for finding people to take over existing farm operations, and part two talks about direct marketing and adding value.
I like the fact that they show how this happens in very different production systems, and on different scales. They are worth a look!
