What you'll learn...

Hybrid Curriculum Preview

For a month before arriving at OAEC, participants will learn foundational permaculture concepts by reading and watching curriculum online. Then students come and spend a week at living and learning at OAEC.  Here, participants will undertake a community-based permaculture design project and will have the opportunity to practice a number of hands-on techniques commonly used in regenerative land management such as swales, composting, food forestry, small animal systems, and wildlands management.

The curriculum and learning objectives for OAEC’s Permaculture Design Certificate are adapted from the Permaculture Institute of North America’s Core Curriculum.

Online Foundations: Participants will read and/or watch four lessons to prepare for the week at OAEC.

You will be required to complete an online quiz at the end of the online portion of the course to make sure that you’ve completed the readings and have a good handle on the foundational concepts.  Being well-versed in the basic principals of permaculture before arriving at OAEC will be key to making the most out of our time together and will allow us to really focus on the application of these concepts.

The material will include:

  1. Introduction to Permaculture
  2. Earth Systems Science
  3. Justice and Ecology Framework
  4. Permaculture Design Process:
    1. Site assessment: map making, pre-site assessment, site assessment
    2. Visioning: client interviews, north star vision, functions, elements
    3. Design Process: Zones, bubble mapping, access, water, food, shelter, community, final project presentation
  5. Climate and Justice
  6. Water Systems
  7. Carbon Cycling

During the In-person Week at OAEC, we will complete the following:

  1. Permaculture Design Project – The class will work with a local community organization and create several permaculture designs that will be presented to them. Teams will undertake site assessment, visioning, and conceptual design during the in-person week.
  2. Hands-on Practices – We will learn how to apply a toolbox of different regenerative land management practices, such as:
    1. Water systems – water infiltration techniques like swales and sheet mulching
    2. Carbon cycling – composting, vermiculture, humanure
    3. Annual gardening – bed prep, planting method, seed saving
    4. Perennial food forest gardening – design, plant selection, planting
    5. Wildlands management – fuel load reduction, brush berms, gully repair

Frequently Asked Questions

What kind of technology will I need?

You will need a computer, access to a reliable high-speed internet connection for the on-line assignments, and a Google account for using Google Docs, Slides, etc. You will also need to download Zoom prior to the orientation meeting. Access to a printer is useful, but not necessary.

How much time should I budget for the online portion? 

During the month of online foundations work, you will read and watch online content approximately 4 hours per week. The lessons are self-paced, so you can plan your time according to your own schedule.

Are there any books or materials I will need to purchase?

No. Aside from the technology mentioned above to access the course, all of the necessary information and materials to complete the course are provided. There are books and apps that we suggest but are not required. Here are a few of our recommended (again, not required) readings that you may wish to start delving into as you familiarize your self with the discipline of permaculture:

• Permaculture Design: A Step by Step Guide by Aranya
• How to Grow More Vegetables by John Jeavons
• Rainwater Harvesting for Drylands and Beyond by Brad Lancaster Volume 1

What should I expect during my week at OAEC? 

On Saturday, you will arrive at OAEC at 12:30 pm to move into your housing and then tour the site. We will wrap up by 12 noon the following Saturday.

Each day, we will meet from 8:30 am until 8:30 pm doing hands on learning and undertaking the design project.

Participants should come prepared to work outdoors in all weather conditions. Please bring a wide-brimmed sunhat, multiple layers for chilly mornings and evenings outside, sturdy shoes or work boots for gardening, plus work gloves and hand pruners if you have them.

We will have three organic, vegetarian, farm-based meals each day.

Students stay in shared accommodations (2 to 4 people per room) and shared bathrooms. Currently, we are offering permaculture students the option to camp in our 80-acre backcountry with a strict no fires policy (If you are interested in camping, please indicate this on the registration form.) While the schedule is fairly packed with course time and field trips, students have access to the hot tub, swimming pond, hiking trails, etc during breaks. See our Visitor Info and Visual Tour pages for more about food, accommodations, parking and other details on what to expect.

What Covid protocols are in place for the residential week at OAEC? Are participants required to be vaccinated?

We will be adhering to recommendations from the State of California and our local Sonoma County Department of Public Health, which may change as the course date approaches and the dynamic conditions of this pandemic unfold.

While some of our time together will be spent outdoors in the fresh air where social distancing is possible, participants stay in shared sleeping accommodations and use common indoor spaces such as dining facilities, classrooms, bathrooms etc. Out of care for the safety of our residential community and visitors who also use these shared spaces, all OAEC staff and residents are vaccinated against Covid-19. As of now, OAEC requires that course participants be vaccinated, unless they have a documented medical exemption. Upon registering for the course, you will be asked to provide proof of vaccination or documentation of medical exemption.  We are also requiring a negative covid test dated 48 hours before the start of the course for all participants. Please read and agree to our Covid Safety Protocols for Summer 2022 Permaculture Courses page before registering.

We appreciate your understanding and collaboration as we navigate how to best support everyone’s health during this still-changing pandemic.


Our Site

Everything we teach in our course is deeply steeped in decades of lived experience on the land and in relationship.

For over 25 years, the Occidental Arts & Ecology Center and onsite intentional community have been tending the land through ecological design on our 80-acre demonstration site and home in western Sonoma County, California. As the longest continuously operating permaculture center in the West, it is considered one of the nation’s best examples of a working site that is set up as a holistic, well-functioning organism at every level. This is our classroom. There are a wide array of integrated systems in action here that students have the opportunity to interact with – grey water, roof water catchment, composting toilets, erosion control and storm water management, seed bank, food forests and biointensive gardensWildlands tending and restoration, natural building, etc., in addition to innovative structures of self-governance in community. We’ve experimented with lots of ideas over the years and many of them failed – students get the benefit of learning from our mistakes!  

In addition to the hands-on learning that our site provides, students also get to taste the fruits of the land including delicious organic vegetarian meals based on produce from the OAEC garden and orchards. Students stay in comfy eco-dwellings and can enjoy other amenities such as our hot tub, sauna, hiking trails and swimming pond. Watch the visual tour of our retreat facilities.

Our Approach

We have translated hard-learned lessons from the land and our relationships into a design methodology that empowers you to not only Do-It-Yourself but to Think-It-Yourself; to apply elegant theory to the complexities of real places and people.

We teach Resilient Community Design – where ecosystem meets ‘ego-system.’ In this course, you will get to practice skills in group process, democratic decision-making, and self-governance as you work with your small design group. We practice what we call “public permaculture.” The ethics of “Earth Care, People Care, Fair Share” are baked into the course structure as the design practicum is focused on creating a design for a local community group.  Past Permaculture courses have co-created designs with organizations such as: The Cultural Conservancy, Saint Steven’s Church, Occidental Center for the Arts, Northwest Prep School, and more.

Our work comes out of years of community organizing at the inextricable juncture of social justice and ecology and a long-standing history with the Movement Generation Justice and Ecology Project. From a systems theory perspective that is rooted in justice, this course will help you identify false solutions and understand that true sustainability requires uprooting systems of oppression at every level. We will examine historical legacies and current legal, financial, cultural violence that separates people from the land and incentivizes unethical land management. We will focus on ways to legalize sustainability at the policy level and build ‘infrastructures of justice’ on the ground in our homes and communities.

Our certification program is accredited by the Permaculture Institute of North America (PINA).

The PDC course at OAEC is part of a larger Resilient Communities program and social change Vision & Strategy that extends well beyond the physical site. OAEC is at the forefront of several important regional-scale campaigns to Change the Rules at the local and state level to support sustainable systems of governance and economy. One exciting example is the Compost Toilet Research Project which is currently trialing three different mid-sized commercial scale composting toilet systems to provide data and recommendations to our county regulatory officials.


“Thank you for giving me the roadmap back to right relations with the earth. After decades of schooling on engineering our environments and 'reducing impact,' the PDC has ignited an intuitive capacity to observe, imagine and act with integrity and humility. Regenerate, we will!”

“I appreciated the emphasis on social permaculture and the importance of communication within community. OAEC is a great living experiment to witness.”

“The course exceeded my expectations. I see and think differently now. I think the concept of humans co-evolving with nature was my biggest take away. I felt like I was relearning skills and an intimate way of seeing that I used to know as a kid roaming the forest – that my initial intuition had been right all along before I got bombarded with our consumerist society. I have so much to think about.”
