Jean-Martin Fortier is a farmer, author, educator, and advocate for regenerative, human-scale, profitable agriculture. For over 20 years he and his wife Maude-Helene Desroches have operated les Jardins de la Grelinette, a successful 2-acre microfarm. His bestselling book The Market Gardener, which has sold a quarter million copies in nine languages, describes the biointensive principles used at his micro-farm. In 2015, he established a research farm, la Ferme des Quatre-Temps, where he trains apprentices and develops new strategies for market gardening, including year-round production. His methods of production are taught to a worldwide audience through the Market Gardener Masterclass, an online course of the Market Gardener Institute, which is tailored to small-scale food growers. He is the founder of Growers & Co., a tool and apparel company which celebrates sustainable, local, and equitable food producers. Jean-Martin farms and lives in Quebec, Canada.
