With garden season in the Southern Hemisphere getting underway, we’re offering a popular workshop on eco-effective, beyond-organic gardening. Below is a draft for a book proposal that I wrote two years ago before my thesis writing got underway. It should provide an idea of the 4 dimensional design and management strategies we employ in our carbon positive agriculture.

Maximizing Human-Scale Food Production

Organic Weed Control: Human-Scale Design and Management
Weed management is the greatest challenge to both large scale organic farming and the home gardener. Many home gardeners abandon their vegetable patches because they fall behind on weeding and then get overwhelmed. I’ve seen it happen over and over again. It’s a pity because this is completely unnecessary if the garden is designed well in the first place. Planning a garden around weed control may not sound exciting, but the result can save hours of drudgery and frustration, and potentially abandonment. It can make the difference between success and failure, and may mean the difference between a novice giving up after one attempt or making gardening a lifelong passion. For the experienced gardener it means doubling or tripling the size of a vegetable patch with no additional time commitment or expensive mulches.

Low/no maintenance edge even with invasive grasses.
Over the course of ten years I have developed a highly effective organic weed management system that also breaks insect pest and disease cycles, builds soil fertility, and cuts down on watering needs. It is also inexpensive to establish and maintain. The original system, designed for cold climates, relies on a four year rotation in beds from one square meter up to a quarter acre. For milder climates, I’ve modified the system to accommodate six half-yearly rotations over the course of three years. In both systems, an extra year of cover crop/green manure can easily be added if desired.

In an era of rising energy prices, economic volatility, and changing climate it is significant to note that one person can manage up to an acre of vegetables using only hand tools. Forget carbon-neutral. This is a carbon positive system, as it uses no fossil fuels and actually sequesters carbon in the soil. By converting lawn into garden beds, concerned citizens of planet earth can save time, money and carbon by not mowing, and simultaneously increase their personal food security. Anyone can turn high maintenance/low productivity landscapes into low maintenance/high productivity foodscapes. The keys are design, timing and tools.

It is human nature to blossom at the possibility of building something new, but to wilt at the thought of ongoing upkeep. People tend to love projects but hate maintenance. This system is designed with that in mind. The system harnesses natural energy flows, including human energy. After the initial design and construction, ongoing maintenance is kept to a minimum. Time spent on weeding, watering, and pest control are all reduced. The result is more food calories grown on fewer food calories (and no fossil fuels) burned. I have traveled the world looking for examples of sustainable agriculture and have found few better. Where conventional agriculture requires up to 20 fossil fuel calories burned for every food calorie produced, this system reverses those figures. It produces a net energy profit, instead of loss, and uses no fossil fuels at all.

The system relies on thoughtful design, the right tools, and proper timing. It is a low budget system as it relies on a few high quality tools that will pay for themselves many times over in time savings and food production. I developed the system on my farm in Andover, New Hampshire. During my time there, Pedal Power Farm was over 95% energy independent. Keeping costs low and productivity high is crucial to any small-scale farmer. This system is ideal for anyone growing produce in four square meters up to an acre.

As with birthdays, wedding anniversaries and holidays, we met the 10-year anniversary of the plane crashes of the 11th of September divided. Days arrive a day earlier in New Zealand than they do in the USA. As we awoke on Sunday, 11-09-11 in Wanganui, NZ, our families were enjoying an autumn Saturday afternoon in New Jersey, Washington DC, Pennsylvania and Massachusetts. As I write these words on Monday, 12-09-11 in Wanganui, memorial services are taking place on Sunday, 11-09-11 in New York City and elsewhere around the country. Living between two worlds reminds me of an amazing book about the Native American experience called Neither Wolf Nor Dog.













We expressed our need to have sustainability issues linked to science curriculum requirements in the run-up to the Science Fair which has been a bugbear for some. Nelson made the link in a clever way linking ideas with a narrative style. Many staff spoke to me about how useful the session was and ALL asked for follow-up.
-Keith Beautrais, Head of Science and Environment, Wanganui Intermediate School.
Was invaluable to have so many ideas that are quick to set up, cost efficient and aimed at the students level.
– Teacher, Wanganui Intermediate School.
Nelson was really involved and passionate in his discussion with the kids – in turn this has helped them to get into their research.
– Teacher, Wanganui Intermediate School.
As a first year teacher I found the presentation provided me with a lot of ideas to hap me to guide my class in their projects. Enviro was not an area that I felt confident to suggest to my students as a topic for science fair until I heard Nelson’s talk.

This excellent feedback is joined by similar compliments on other educational projects we’ve done outside of schools. This one comes after a powerpoint presentation on “The Principles of Eco-Thrifty Renovation” presented to the Pukenamu PROBUS Club. (PROBUS stands for professionals and business people. Mostly retired.)
Many club members have said to our committee how much they enjoyed the talk and generally they were amazed at what you have been doing and what you have achieved. Your power bill shows just how much we could all save for ourselves and for this earth if our building practices and living styles were focused on the principles you espouse.
– Colin Clancy, President, Pukenamu PROBUS Club
A colleague in the field of environmental education just told me that she presented the idea of the Eco-Thrifty Renovation to a group of 300 at a professional development programme in Winnepeg, Canada. And I just received confirmation that I will be presenting the ETR at the New Zealand Association for Environmental Education conference in January. Here is the abstract as submitted.
A Whole Community Approach to EfS
Introduction: The ECO School is a tiny organisation presently operating in Wanganui. It’s current focus is a project called The Eco-Thrifty Renovation, which takes a multi-modal, multi-generational approach to EfS, and has achieved outstanding success in just its first 9 months.
Content: The Eco-Thrifty Renovation is a 12-month project to turn an abandoned house on a weed-infested section into a sustainable urban homestead while sticking to a tight budget and abiding by the New Zealand Building Code. Meanwhile the project is being used as the context through which to bring EfS to learners in our community from Year 1 all the way through senior citizens. The educational effort emphasises: saving energy through passive solar design and energy efficiency; growing food organically at home; and saving money through the first two emphases. Thus far, the ECO School has partnered with Sustainable Whanganui to bring the lessons of this project to Year 1 and Year 2 classrooms, all intermediate years, and senior secondary students, all within the framework of The New Zealand Curriculum. Additionally, the ECO School runs weekend workshops for adult learners and has presented to the Senior Lions and PROBUS clubs.
Perspectives: This educational effort takes a permaculture perspective that highlights multi-functionality. In other words, this one project provides both formal and informal education, reaches multiple generations of learners, and addresses both ecological literacy and economic literacy.
Summary: The Eco-Thrifty Renovation offers a unique permaculture approach to providing EfS to an entire community of learners. Feedback in just the first 9 months has been excellent.
We have even been getting positive feedback from the red shavers lately.

And even the pekins are contributing…

… to the extent they can.

But we’re still waiting on some donors.

So this is the first appeal that we’ll send out to potential donors (this means you) for a raft of potential projects to come. If you have enjoyed this blog, if you have learned something from this blog, if you have laughed at this blog, then maybe you can give something back to our education work. We are currently looking for funding for the following programmes:
Solar Sausage Sizzle. For classrooms in Wanganui schools.
Keen Green Teens. Leadership training retreat for high school students in our region.
Kai and Comfort for Kids. An educational programme for parents and guardians on low incomes that shows inexpensive ways to grow food and make houses warmer.
If you are interested in learning more details about any of these programmes, please contact us through the ECO School email.
