After studying biodynamic agriculture at Emerson College, he established a mixed community farm in Wales in 1973, producing at various times: wheat for flour production sold locally, carrots and milk from an 85 cow Ayrshire dairy herd, now made into a single farm cheddar style cheese.
He was the founding chairman of British Organic Farmers in 1982, before joining the Soil Association, where he worked for nearly 20 years and during which time the organisation led the development of organic standards and the market for organic foods.
His advocacy for a major global transition to more sustainable food systems now entails international travel and regular broadcasts and talks at public events.
He is Patron of the UK Biodynamic Association and was awarded the CBE for services to organic farming in 2005.
