Biodynamic Demeter Alliance Welcomes New Executive Director

As the world faces an ever-growing crisis—of climate, soil, water, even spirit—it has become increasingly clear that the Biodynamic movement plays a vital role in building solutions. Thanks to the efforts of many throughout the U.S. Biodynamic community over a number of years—and a collective desire to galvanize resources and strengthen the movement in order to “meet the moment”— the Biodynamic Demeter Alliance was born on January 1, 2022, unifying the Biodynamic Association and Demeter USA. The goal was to create an organization that could serve as a national network to offer leadership in the United States in helping to solve the multiple layers of crisis we find ourselves collectively facing. After an extensive and rigorous national search, we are pleased to announce Sheila Foster as the first Executive Director of the new Alliance.

Let's Start a Dandelion Festival!

By Sonomi Obinata

In the middle of the cold winter, we farmers get to sit and think thoughts, and imagine the wonderful things we will create when warmth returns with spring. It was January 2016 when I attended the Pfeiffer Center Midwinter Agricultural Intensive. We focused on the study of two biodynamic preparation plants: yarrow and dandelion. This study inspired me to start an event on (then) KK’s The Farm, which I called the Dandelion Festival. I wish everybody would host an event dedicated to the dandelion to celebrate the wonders of spring.

In our studies, longtime biodynamic practitioner and teacher, Harald Hoven, instructed us to stand next to the dandelion and to observe the plant, first looking at it out of focus then in focus. I asked inwardly, "May I know who you are?"

Introducing Biodynamic Hemp

By Isaac Daniel and Josh Gulliver

“Hello! We’re new around here and really excited to be a part of things, but you might need to show us around a little.” There’s really no better way for us to start. The two of us, Isaac and Josh, are both newcomers to biodynamics, new to Demeter certification, and we happen to be working with hemp, an area that is also somewhat new to biodynamics. We are new faces in a newer industry to biodynamics, and it is a beautiful place to be.
