At the dawn of this new decade, you can renew the vitality of the earth, the integrity of our food, and the health and wholeness of our communities by becoming a member of the Biodynamic Association or renewing your membership now, and inviting friends and family to join you in membership. Members are the living essence of the Biodynamic Association, and to start 2020 strong our goal is for 500 members to renew or join before April 30, collectively giving at least $50,000 in member dues to support the work of the BDA.

This year, two donors have stepped forward to match your membership gift dollar for dollar, up to $16,000. When you give generously, your membership will go twice as far in bringing biodynamics to meet the challenges and ensuring the BDA can continue connecting, sharing, and revitalizing the agricultural movement!

Who We Are

The Biodynamic Association (BDA) awakens and enlivens co-creative relationships between humans and the earth, transforming the practice and culture of agriculture to renew the vitality of the earth, the integrity of our food, and the health and wholeness of our communities. 

We are a participatory, membership-based nonprofit organization that works to nurture the North American biodynamic movement as a diverse, collaborative, and thriving ecosystem.  We aim to incubate strong leadership in the biodynamic community; grow the community of biodynamic farmers, ranchers, gardeners, and land stewards; communicate the powerful vision of biodynamics and the potential it holds for the Earth; and nurture the deep spiritual roots and insights of biodynamics.

Biodynamics is a holistic, ecological, and ethical approach to farming, gardening, food, and nutrition. Biodynamics is rooted in the work of philosopher and scientist Dr. Rudolf Steiner, whose 1924 lectures to farmers opened a new way to integrate scientific understanding with a recognition of spirit in nature. Biodynamics has continued to develop and evolve over the past century through the collaboration of many farmers and researchers. Around the world, biodynamics is alive in thousands of thriving gardens, farms, vineyards, ranches, and orchards. The principles and practices of biodynamics can be applied anywhere food is grown, with thoughtful adaptation to scale, landscape, climate, and culture.
