OACC is not a formal organization nor is it an advocacy group that promotes an agenda, and it typically does not state positions on current issues. Rather, it is more of an ecological network and a forum for idea exchange; individual participants work in their own respective fields, but meet annually to share about their work.

Participate

We are gathering for the 46th annual OACC on September 26-28, 2025, at Hammond Mill Camp in Missouri. You're invited to attend all or part of the event. This year's theme is "Mapping our Abundance: Matching Needs and Yields."

Volunteer.
Donate.
Co-sponsor.

OACC as a ā€œcongressā€ is distinguished clearly from a run-of-the-mill ā€œconferenceā€ in that it is a gathering of peers who inexpensively and on a volunteer basis organize and conduct the event as a temporary green ā€œvillage.ā€ Decisions are made by consensus during a whole-group plenary session.

Contribute

Each year at OACC, everyone helps out: preparing food, providing our own entertainment, giving presentations, leading discussions, and cleaning up.

You can contribute in so many ways: bring food or fundraising auction items, sign up for kitchen shifts, host a nature activity for children, tell about your advocacy work, or share your Ozark poetry, photos, or expertise.

OACC is organized and run by volunteers. It is not a money-making event for any individual or organization, and we have always been committed to keeping registration fees as low as possible. Co-Sponsors are the key to keeping our rates affordable.

Co-Sponsorship

Co-Sponsors are individuals, groups, and businesses who support our efforts to realize an ecologically sustainable bioregional economy. Being a Co-sponsor puts you at the forefront of making our gatherings successful, by providing a financial foundation for OACC's continuity.
