Antonio Roman-Alcalá is a food activist, gardener, teacher and scholar. In 2005, with a group of friends, he broke into a vacant lot by the freeway in the southern part of San Francisco to start Alemany Farm. He has taught Ecological Horticulture there and at many other food projects. He managed a food justice project and garden at San Francisco’s Potrero Hill public housing and organized the San Francisco Urban Agriculture Alliance. He made a movie called In Search of Good Food, and worked on forming the California Food Policy Council. He was part of Occupy the Farm. He recently got a masters degree at the Institute for Social Studies at the Hague for research on Food Sovereignty. His current project is a book called entitled An antidogmatist's guide to food systems, and how to change them. He will be writing the book blog post by blog post, and you can read it as Antonio writes it at antidogmatist.com -- starting soon in the spring of 2016. He is a musician and new father, and lives in San Francisco with his family. Antonio talks with Chelsea about coming out of DIY culture, pushing institutions, and transforming the food system at multiple scales.
