Writing Workshops

Writing About What Matters

Transformational writing inspires others to take action by awakening readers to new possibilities—they leave changed knowing that what they experienced is real. People can and will argue with your interpretation of the facts, no one can argue with the truth of your experience, making a well-told story the most effective tool for persuasion. To create a better story, the most important voice to hear is your own so you can energetically engage in what calls to you. Then you can’t help but speak up and out, the transformational story comes from deep within you and reflects what you most care about.

True Dirt: Bring Life’s Work to the Page

Whether writing for CSA newsletters, magazines, letters to the editor, your friends, or a book deep inside you burning to be written, telling your inner story and experience serves your farm, the food and farming revolution, and your community. This hands-on workshop will include writing exercises to develop your voice and story and reach your readers on a sensory and emotional level. The intellect is engaged to understand the issues–the heart must be stirred to create  behavior change in your reader. Class time will include in-class writing and participatory workshop/sharing.

Consumer Workshops

Our Spiritual Relationship With The Land That Feeds Us

Imagine. If you had a relationship with something that was absolutely ancient, and so precious, that life – including yours – could not survive without it. What would you do to protect it? How would you care for it? Growing food is a spiritual relationship with the life process. Eating is a spiritual act. Our daily food decisions affect the wellness of the land, and the life that lives upon it. Join Atina Diffley, organic farmer and author of Turn Here Sweet Corn: Organic Farming Works for an empowering conversation about our spiritual food relationships—with the earth, plants and animals, families and communities.

Eat, Educate, and Engage in Policy As If The Earth Matters, Because It Does: Biological Diversity, Ecosystem Services, and Organic Farming

Join organic author of Turn Here Sweet Corn: Organic Farming Works, Atina Diffley, for a conversation on agriculture and biological diversity that leads right to our plates and the land that feeds us. An organic vegetable farmer and activist, Atina and her husband Martin operated Gardens of Eagan from 1973 to 2008, marketing direct to food co-op groceries and their roadside stand. Consumers have tremendous power in the work of protecting land and nature and making policy change. Informed citizen input made a big difference when the Diffleys faced the threat of eminent domain by a Koch Industries owned pipeline. The Diffleys intervened as parties to the route proceeding, and created an Organic Mitigation Plan that now provides soils and certification protections for all Minnesota organic farms threatened by a public utility.

Eating As An Earth Advocate: Scientific Findings About Organic Agriculture

How our food is grown has an impact on human health, climate change, food security, biological diversity, air, and water quality. Come hear what the scientific community has discovered about the production practices used in organic agriculture and why the President’s 2010 Cancer Panel Report urges consumers to choose foods grown without pesticides or chemical fertilizers, antibiotics, and growth hormones.
