14th Annual San Juan Islands Agricultural Summit

Growing Resilience

February 27th & 28th

The San Juan Islands Agricultural Summit is a cornerstone gathering for farmers, food producers, land stewards, and community members working together to build a resilient local food system.

In 2026, we return to San Juan Island with the theme “Growing Resilience” — a call to deepen our collective response to climate, land, and economic challenges, and to celebrate what’s possible when island communities come together.

We’re delighted to host Helen Atthowe as the keynote speaker for the 2026 San Juan Islands Agricultural Summit. With more than 35 years of experience linking farming, food systems, land stewardship, and conservation, Helen is a national leader in ecological farming.

2x more likely to have the goal of being a leader
3x more likely to participate in community service
2x more likely to report living life with intentionality and purpose
