Back to the Future: Terra Preta – Ancient Carbon Farming System for Earth Healing in the 21st Century
Courses/Workshops, Rehabilitation, Soil Biology, Soil Erosion & Contamination — by Planet People Passion May 25, 2010
Terra Preta, meaning "Black Earth" in Portuguese, is a soil building technique developed by ancient Amazonian civilizations at least 7000 years ago as a solution to permanently solve the problems of poor tropical soil fertility. Large deposits of this black earth are still found today with depths of up to 2 meters. The first deposits where discovered in 1870, but it has only been in the last 10 years that significant interest and study have been initiated.
This soil is attributed to the complex civilizations that reportedly once thrived in the Amazon. Prior to the onset of diseases brought on by the western settlers, this expansive web of communities is estimated to have totaled over 100 million people. It is speculated that Terra Preta soils are what sustained them in harmony with their ecosystems.

The Amazon rainforest is one of the most amazing displays of symbiotic relationships one can experience in the world. This complex and layered eco-system thrives through the many systems and cycles that interweave through the layers of canopy, creating one of the most bio-diverse displays of life on the planet. Nature designs the most magnificent Permaculture systems – it is quite an experience to spend time in this magical place and humbly observe her teachings.

Observing the thriving and abundant rainforest, it is hard for some to comprehend why neighboring agriculture in the region experiences quite the opposite affect, but the answer is quite simple – it’s all about the soil.

Editor’s Preamble: Permaculturists famously endeavour to ‘turn the problem into a solution’. At the moment we have a tremendous opportunity to apply this principle in wonderful, productive ways in disaster-hit Chile. The quake-tsunami combo that hit on February 27, 2010 has created a void just begging for sustainable relief and re-development. Grifen Hope, who writes below and who leads out at Ecoescuela El Manzano, a partner organisation to the Permaculture Research Institute, is well positioned to fill that void with all kinds of permaculture goodness – in the form of low-cost environmentally friendly buildings, improved sanitation and nutrient cycling through construction of composting toilets, water harvesting systems and in education in home garden design, etc. Grifen’s already established and successful project and his national contacts make this a particularly significant opportunity, to not only directly help people in great need at this time, but to also offer more holistic and community centred alternatives to local and national government – alternatives with far greater short and long term potential than those offered by the scores of contractors seeking to cash in on misery. PRI Australia feels so strongly about assisting Grifen with his noble ambitions, that we’re putting forward the first AU$1,000 donation. Both PRI Australia and PRI USA are taking donations for this cause (people in the U.S. will want to donate through PRI USA, to take advantage of their tax-exampt non-profit status). In the interests of transparency, PRI USA will take 5 percent of donations to cover administration and the work that had to be done to facilitate the legal aspects of sponsoring this project – but that 5% will help PRI USA develop its own projects). PRI Australia will pass 100% of donations to the project in Chile. Additionally, as we feel this work deserves significant exposure, and as we seek to ensure that valuable permaculture relief work gets noticed at the highest levels, to attract further governmental support for future disasters worldwide, PRI Australia and myself (Craig Mackintosh) will share the costs for myself to go to Chile to cover and report on Grifen’s work via photographs, writing and video. I would like to take this opportunity to ask people to get behind this in whatever way they can. Donations, large or small, will all assist in what is the very best form of aid work. Perhaps ask your employer to match your donation – many will. Additionally, people with contacts in government, aid agencies and other NGOs are invited to share this page with them. Thanks in advance to the worldwide permaculture community for getting behind this work. You never know – in the future you may be the recipient of such assistance.

Comments (0)My Experience of Permaculture in Guatemala
Community Projects, Demonstration Sites, Education Centers, Food Forests, Food Plants - Annual, Food Plants - Perennial, Land, Plant Systems, Project Positions, Rehabilitation, Trees, Water Harvesting — by Kevin Mascarenhas February 7, 2010
The Ijatz cooperative is possibly the best demonstration of the transformative power of permaculture in Guatemala. The site, in San Lucas Toliman near Lake Atitlan, was purchased at low cost since the parish council considered the land to be of low value. Previously, it was a swampy bog inundated with refuse and flood water from the surrounding hills.
In classic permaculture style, within the problem lay the seeds of the solution. The deforestation due to conventional agriculture in these surrounding hills has caused soil erosion and during the rainy season much of this rich volcanic black top soil is washed downstream. This annual bounty has been redirected through the Ijatz site using a sequence of channels and sink holes, which in turn slows the water flow enabling the nutrient rich humus to be captured and stored on site. The earth has been moulded to create slopes, edges and contours essential for increased growing opportunity.

Biodiversity, General, Land, Rehabilitation — by Rhamis Kent January 2, 2010
Here’s an idea that should be embraced and championed by all earth repair advocates: The Buffalo Commons.
The Buffalo Commons is a conceptual proposal to create a vast nature preserve by returning 139,000 square miles (360,000 km2) of the drier portion of the Great Plains to native prairie, and by reintroducing the buffalo, or American Bison, that once grazed the short grass prairie.
Comments (0)From Annuals to Perennials
Conservation, Food Plants - Annual, Food Plants - Perennial, Plant Systems, Rehabilitation, Seeds, Structure — by Craig Mackintosh December 19, 2009
Permaculture is all about mimicking natural systems – patterning our agriculture and other critical human needs on the symbiotic processes we observe all around us. If you compare nature’s methods we see that stable natural plant systems are polycultures, and perennial, whereas our modern industrial agriculture is the exact opposite – largely being monocultures and annuals.
But, imagine if the annual crops we rely on the most, grains and pulses, could be made to grow perennially instead. No end/beginning of year ploughing, no annual replanting, etc. It would save enormous amounts of time and energy on cultivation and planting, and allow soils to remain undisturbed for longer, with immense benefits to soil life, structure, organic matter and carbon content.
The video below highlights this out-of-the-box permaculture thinking. The Land Institute in Kansas has been working solidly on engineering annuals into perennials (by way of natural plant breeding – not by gene gun). They take ancient wild, perennial varieties of grains, and cross them with their modern annual counterparts, and repeat, and repeat, until they end up with a harvestable product from a plant that doesn’t have to be resown every year. Or at least that’s the aim. This is still a work in progress, but their purpose is "to develop an agricultural system with the ecological stability of the prairie and a grain yield comparable to that from annual crops".
Comments (0)Yeomans’ Pioneer Demonstration Site to Be Turned into Housing Estate
Conservation, Demonstration Sites, Irrigation, Land, Rehabilitation, Structure, Water Harvesting — by Craig Mackintosh
One of the most influential people in sustainable agricultural systems development is the late P.A. Yeomans. Yeomans went against the contemporary fertility-in-a-bottle school of thought to develop ‘keyline’ concepts of land management that work in harmony with natural land features (working with contours), to maximise water harvesting in the landscape, minimise soil erosion and build lasting soil fertility. His observations and practice led him to design and develop the keyline plow, a deep chisel plow that maximises water infiltration and soil aeration – setting up conditions that soil macro and microorganisms can flourish in – but that doesn’t overturn the soil, with its associated destruction of soil structure and life, as other plows do.
The ABC just ran an interesting spotlight (video – or transcript here if you prefer) where we learn that one of Yeomans’ properties, ‘Yobarnie’, in Richmond, north of Sydney, is facing ‘development’ that would turn this important historical demonstration site into a housing estate. In the 1950s and ’60s the site attracted busloads of people on weekend tours where observers could see the transformation his methods effected and learn about their implementation.

 What Manhattan may have looked like… |
Often, as I’ve travelled and lived in different parts of the globe, I’ve stood on mountains and beaches and looked around, somewhat wistfully, trying to visualise how those landscapes would have looked a few centuries ago. I’m sure you’ve done it too.
Many, if not most, of these places were once vast tracts of old growth forest, with rich diversity in flora and fauna. Natural biological water cleaning systems were in place, as the hydrological cycle was efficient and largely unmolested by man. Most places still had rich, dark soils and no chemicals had yet been employed to stamp out soil life.
These were the days of 280ppm. We lived then with respect, if not even fear, for a nature wide and wonderful – never for a moment thinking we could one day be the cause of these vast and mysterious systems collapsing wholesale.

The Greening the Desert II video I shared with you recently was edited in Jordan. Now that I’m back at my desk again I’ve had time to edit it slightly. I’ve added the original five-minute Greening the Desert clip in to the front of it, to ensure viewers have context for Part II (and we’ve also had requests for both to be made available together), as well as cut a few minutes out of Part II to keep it flowing a little better. You can not only watch online below and embed on your own websites (click for embed code at top right of video screen), but it’s also available for download, so those who’d like to have a ‘hard copy’ to circulate are welcome to download, burn to disk or transfer to USB key, etc., and circulate freely.
Download: You’ll see the option to download the 913 megabyte MP4 file at bottom right side of this page.

I would like to take the opportunity to thank Kelly Kellogg at this juncture. Kelly donated initial funding that enabled the purchase of the land for the Jordan Valley Permaculture Project site (aka ‘Greening the Desert – the Sequel’). But, upon watching the Greening the Desert Part II video, Kelly was inspired to donate an additional $20,000. These gifts are very encouraging to us as we try to solve problems at source (teach a man to fish…). Others who may feel inspired to donate to help us move this work forward faster can do so here.

The video embedded in this page spotlights the excellent work of Willie Smits I profiled a little while ago, where rainforest restoration in Borneo not only restored biodiversity and gave increased livelihood opportunities to local people, but it also increased cloud cover and rainfall as well. It’s well worth a watch:
We’re pleased to announce that we’re partnering with the makers of the video above, WeForest, to help establish self-replicating permaculture reforestation demonstration sites in accordance with our Permaculture Master Plan, in several worldwide locations – starting in Zambia in the first instance. Our Geoff Lawton has just agreed to be on their advisory board, and we’ll be working to supply guidance, knowhow and staff to pioneer these projects.
This is just one example of the many encouraging collaborative results we get as people boil current events down to their only logical conclusion – discovering we need to quit battling nature and get busy harnessing biological synergies to repair the earth and rebuild sustainable community interactions.

Geoff Lawton and Darren Doherty are the two highest profile people in Australian Permaculture when it comes to broadacre water harvesting earthworks. They’ve both had success in some very tough environments, and yet it’s interesting that their styles are quite different, particularly when it comes to infiltration strategies.
This article is a short comparison of their approaches, along with an idea I had recently for amalgamating the benefits of each.

That comment use to cross my mind, but luckily I got over it.
I completed my PDC in January ‘09 with Geoff at Zaytuna farm, along with a lovely range of fellow students from the far reaches of the globe. I sincerely hope they also post stories to share – come on guys, it’s time to be brave!
I returned to my home in south western Victoria (Australia) a changed woman, and I sometimes wonder what it was I use to believe in before I was transformed.

I recently had opportunity to visit a Permaculture site called ‘Dalpura Farm’, near Geelong, outside of Melbourne. Although (or perhaps, because) designed by Darren Doherty, the very well known Permaculture designer and teacher, it was dramatically different than your average Permaculture site. Rather than an urban edible garden, or a fruit-/veg-/livestock-oriented rural block, this 140-acre property was all about trees.
It’s an experimental agro-forestry project, aimed at finding the best way to produce a range of commercial products and ecological benefits from trees, with timber production being the primary focus.
I contacted Darren, the designer, and George Howson, the owner of the property, to see what it was all about.

A wise person once said that soil is not only more complex than we know, it is more complex than we can ever know! The good news is humans have lately achieved a level of practically applicable knowledge and experience in soil biology to be absolutely capable of massive, positive impacts on sustainable soil use world-wide! It is undoubtedly true that we’ll never know everything, but no matter – we already know enough to get very, very busy!
