Avalon Organic Gardens & EcoVillage in Tumacacori, Arizona invites you to join us in an exciting and innovative approach to community development and cultural enhancement. Our model community of 115+ men, women, and children is an experimental prototype intentional community designed to be replicated throughout the world, and is the largest EcoVillage in the United States. For over 25 years, we have been working cooperatively to construct this learning center in an effort to share the fruits of our labor with other planetary citizens.

We are offering people, individuals and groups alike, the opportunity to come and learn about our method of sustainability through practical advice. We'll be providing the necessary knowledge and tools to replicate this model of living anywhere. The world is rapidly changing and many of our resources are being mismanaged and/or are in very short supply. It is with the utmost sense of responsibility and accountability that we share this wealth of information with you.

Please note: This Earth Harmony Sustainability Seminar is an academic series of panel sessions designed to teach practical lessons for building ecovillages and sustainable communities. While it provides an immersive, live-in study of a fully operational ecovillage, it is not a Hands-in-the-Soil experience. It is academic in nature. If you want a Hands-in-the-Soil experience, it would be best to come and take an agricultural internship.

Optionally, register to arrive early Wednesday & Thursday in advance of the seminar for 2 days of mini-internship, hands-on in the soil. $150 extra for these 2 days (recommended as it is only half-price). Meals included.
