The Biodynamic Farming and Gardening Association (BDA) membership-based nonprofit organization in North America committed to the transformation of the whole food system, from farm to table, drawing inspiration from the spiritual-scientific insights of Rudolf Steiner. Biodynamics is a worldwide movement for the renewal of agriculture based on an understanding of the spiritual forces at work in nature and in human social life. From this understanding, a particular form of organic farming has been developed that continues to grow and evolve around the world.
