The ‘Adobe House’, El Manzano’s ecological demonstration house.

In the middle of the little El Manzano village, on display to all in the community, is the ‘Adobe House’. This demonstration house is a project by Eco Escuela El Manzano to demonstrate to the community several low-tech but effective techniques for improving quality of life whilst reducing a home’s impact on the environment.

Houses made from adobe bricks are common in Chile, although, increasingly, like many ‘developing’ countries, people are turning towards energy disastrous concrete instead. The Adobe House was not purpose built – rather, it is actually a very old house that was retrofitted in 2008. It is thus a good example of what many villagers could do if they had a mind to.

I’ll share a few of its features.

Against one wall they built a simple conservatory. The earth brick wall absorbs heat during the day, warming the home, and radiates it back out during the night – to ensure an extended frost-free period for vegetables. Well positioned terracotta tiles or other high thermal mass elements can increase this energy buffering as well (even just barrels of water can do the trick). Though not incorporated here, another addition can be to add vents between the conservatory and the home to allow excess heat to pass into the house.

During the hotter parts of the year the ends of the conservatory are easily opened up.

Outside the house and conservatory there’s a trellis hung heavy in grape. It creates an excellent, and edible, shade area under which sits an outdoor table and benches for summer breakfasts and lunches. The foliage dies back during the winter months to let more sunshine through.

Next to this sits a fantastic earth oven. And yes, the bread was as good as it looks:

Other elements include the all-important manual pump for water – without which this community would have suffered dearly during the recent earthquake (see Part I) – and a greywater system for biologically cleaning household waste water, returning it, slowly, to the water table after several stages of natural cleaning.

Potty Training

The ‘centrepiece’ of this demonstration site, however, is this:

A composting toilet (or ‘dry toilet’ as they’re called here)

This elevated, dual-chamber throne room (similar to the one at Zaytuna Farm) serves as the home’s fertiliser collection station. When enconsed therein, or thereon, as the case may be, the room is notable for its lack of odor. Any odor.

Although composting humanure should be regarded as an urgent… um… call of nature everywhere (the world is running out of potable water, and yet we’re crapping in it, and we still haven’t come to terms with the significance of phosphorus recycling yet either), it is arguably even more important here in El Manzano.

I say this for two connected reasons: 1) most of the community here rely on ‘long drop’ toilets (simple holes dug into the ground), and 2) the water table in El Manzano is incredibly close to the surface – in many places barely a metre below ground.

In case the obvious eludes you – this means that these smelly, bacteria-filled repositories will be seeping into the water table…. Yes, this is the same water table they’re pumping water from so as to quench their thirsty lips. If it weren’t for the very low population density here I think we could be looking at some serious health issues.

The Eco Escuela El Manzano team are therefore turning the problem into the solution, by demonstrating how a potentially disastrous waste stream can instead become a resource. The Abobe House has a constant stream of students and interns residing in it – all of whom are building site fertility rather than contributing to water contamination.

With the high risk of our seeing hyperinflation hit us sometime in the next 2-3 years, many are wondering what to do with their money before it becomes worthless. This is why serious investors have at least part of their portfolio in tangible assets such as gold or land.

For a long time I wanted to buy some land and do something with it, but where I live the land is stupidly expensive (particularly for small amounts), the prices propped up by grants and other scams. I knew there was affordable land in other parts of the world but I had neither the contacts nor the confidence to do anything. Recently I bought a small piece of land in Morocco to build a school and internet project, based around permaculture. Having gone through the purchasing process, with some good friends over there helping, and having the deeds in my possession, I am in a good position to help others do something good with their money.

Starting from the edges, it is quite possible to turn the desert back into a forest. Your investment would be part of the first stage, using permaculture principles to halt the spread of the desert, bring back fertility and then eventually expand into the sand dunes. Reforest the Sahara and not only keep your capital, but also have a good chance of increasing its value massively. Use your ‘insider knowledge’ of permaculture to invest in the real future.

The land I bought was quite fertile agricultural land, and quite expensive; altogether with legal costs it was about 3000 euros for a hectare or so. There’s marginal land in the area much cheaper because people don’t realize what can be achieved on such land. I was inspired by the whole region – it’s turning to desert but could easily be turned around with a little judicious planting and a respite from the goats. Anyone (or a group of friends) with around 3,000 euros could buy some and make it into a forest. This is the kind of land I’m talking about:

How it Works

We act as an agent:

• for the initial purchase, ensuring that the purchaser has legal title
• to employ local people to do the work
• for any subsequent sale or transfer

The agency would be entirely voluntary, no long term contract or penalty clauses. If you decide to manage your own land, or appoint someone else at any time, you are entirely free to do so.

The fees to cover labour and expenses could be annual or monthly, with no obligatory minimum, and as more land comes into the scheme the labor costs per acre would go down. As the land develops into forest, you will have crops such as nuts, fruit and olives, as well as timber. These can be used to pay the workers maintaining the forest, thus offsetting the ongoing expense altogether. All this can be managed for you by us, or by anyone else you choose to appoint.

Much of the initial work could be done as part of the courses we’ll be running for local people, as well as international students, volunteers and interns, who would benefit from the experience, This would mean you would not need to pay much for the time it should take to become productive enough to cover costs. After the intial earthworks we could pay someone 20 to 25 euros for a full day every now and then, at your discretion. The more work is done, the faster it will develop. This need not be intensive permaculture, more like zone three or four.

We can arrange hospitality and accommodation for you at local rates, so you can visit the project and see your land at any time with minimum cost. The area we are in has stunning scenery and welcoming people, so this could be a low-cost and unique holiday for you too.

Advantages over traditional ‘charity’:

• Totally Ethical (your ethics). Your children’s world will be enhanced by your investment, and no damage is done anywhere
• Land price would increase as the whole area becomes fertile. So your investment starts to grow even just in cash terms very soon
• The investment is under your control completely. You can run it yourself or appoint someone else as an agent at any time
• It’s free from the pitfalls of fiat currency, which affect virtually every other form of investment except things like gold
• None of your money is wasted. Most organizations spend a significant proportion of your donations on administrators, offices, computers etc. We will be using the already existing resources of the School/Permaculture Centre.
• You get to do something useful with your money and still keep it!

Small is Beautiful

By keeping the operation small we can save costs and avoid the burgeoning bureaucracy that plagues many projects.The core operation—the land agency and work co-ordination—can be done by two people, who will use the same resources as all the other projects, and not rely on this as a full-time job. Thus commission and admin fees can be kept to a bare minimum. The vast majority of your money is in the investment itself, and fees are in line with those of banks and other investment agents. The work will be carried out by local people trained on the permaculture design ceritifcate courses at our centre. Thus the communty will see immediate benefits from the project.

You Choose the Kind of Forest

• Food Forest: This is a diverse woodland designed with an overstory of thngs like palm, wth many fruit and nut trees growing beneath it, as well as a thriving support community of plants and animals. It mimics the natural forest system, producing a sturdy and stable ecosystem with abundant food and water. This is the best for our area, as it has a human population and we need to convince the locals of the benefits of permaculture.
• Timber: Similar design to the food forest, but with an emphasis on trees that wll be valuable for timber when fully grown.
• Wild: This would be left alone after some optional initial earthworks to preserve water. Many people believe wild land is worth nothng, but you only need to look at the degrees of corruption timber companies will go to in order to exploit the Public wildlands in the USA to see that this is not true. Usually there is quite an expense in fencing for this knd of project, but the goats here are herded, not free-ranging, and the locals will respect your wishes and not graze the land. There are wild baby-tree predators but the removal of the goats will be sufficient to ensure success.

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.

During the dry season any rainfall is held in the pond sequence, maintaining the local water table which is the source for the hundreds of trees and plants. While the flora perpetually contributes biomass to improve soil fertility, a micro climate suitable for growing has developed in what is essentially a few acres on the edge of town. Prior to the establishment of the Ijatz project, over one hundred homes were annually flooded in the immediate vicinity. Currently, the site can receive flood water to the depth of more than a metre during the wet season. A perfect demonstration of a multifunctional permaculture design element, the banana circle has provided the solution. Acting as a pump, that most excellent of pioneer species, the banana simply sucks up and holds this water. The spaces between the rubbery concentric rings of a banana tree are simply saturated in water. The centre of the circle becomes a compost heap for any site prunings while the worms of the vermicomposting stations make short shrift of sections of banana trunk. The composted output is another useful income stream for the coop. Of course, let us not forget nature’s own delicious potassium stick – the banana itself! All this and the local community benefits from dry homes throughout the rainy season too. This in turn satisfies one of the cornerstone ethics of permaculture: people care – positively affecting the local community.

Banana circle

The project is only thirteen years in the making and boasts a diverse range of trees and plants that reach every level of the canopy. Timber is harvested and the bamboo stands are about 6m tall. There are a number of guava, grapefruit, lime and lemon fruit trees. A vine layer producing a vegetable called güisquil (sechium edule) when boiled is similar in texture and taste to a tender swede or turnip. There are several other local tropical plants that contribute roots or leaves to the kitchen table. The annually deposited soil is then built up to form raised beds for growing vegetables. My three week stint centred around reinstating the vegetable and herb beds preparing them for fresh seedlings, including lettuce, coriander, frijoles (beans), parsley, celery and radish. This soil food web is teaming with life and I encountered countless worms, spiders and other small creatures. Thankfully, the nesting cobra we stumbled across only wrapped itself around Pancho’s arm (the head gardener). No harm done – sadly only true for Pancho!

The core focus of the Ijatz cooperative is coffee production. On the final day of my visit, the ladies of the cooperative harvested fifty kilos of coffee beans ready for processing. However, they collectively own several plots of land on the slopes of the now extinct Volcán Tolimán. Through the cooperative, the workers have generated a stable income which has funded educational programmes on child care and nutrition. They also have discussions to understand where their high value product sits in the open market. I was invited to describe the drinking habits of Europeans. My talk was graciously received even though my Spanish is woefully short of adequate.

If you are interested in volunteering your time and energy to the assist the Ijatz project and you have a command of Spanish language you can contact them directly at asociacionIjatz (at) gmail.com otherwise I can advise you. Volunteer opportunities exist throughout the year.

A gentle slice of moon on the star crowded sky of southwestern Madagascar just set gracefully and yet another day is over; we are now in the second half of January 2010.

And what day is today: Monday, Wednesday or perhaps Sunday? We easily lose track when in the field, especially during our prolonged stays – keeping busy in the nursery, forest and the village of Ranobe with several community participatory projects – keeping the momentum of excitement and action. The dynamics are encouraging and there is wonderful energy flowing. Every day is somewhat special; ups and downs along the journey to the ultimate balance. Capacity building is about trust building and about generosity, patience, humbleness as well as discipline. It’s a wonderful lesson for all of us, for ho avy team and for FIMPAHARA.

And what is the fresh news? Ino vao vao? As expressed in Malagasy. Aha… tsisy vao vao, is the universal answer – there is no news (even though there actually are news). In fact, misy maro vao vao – there are many good news in the process of ‘growing for the future’. And so let us fill you on those:

Work in our three native tree nurseries has been truly a rewarding time; reconnecting with nature and sharing the cheerful time with FIMPAHARA members actively involved. It’s been a pleasureable time of nature observations, provided that we are situated between a nice patch of mostly continuous forest in southwestern Madagascar and diverse agricultural land. Our nurseries attract a lot of incredibly interesting wildlife. Spectacular wildlife moments are abundant: we have been observing several local endemic species of frogs, a slim worm-sized transparent skink Voeltzkowia sp. ‘pallida’, about which not much is known, ancient looking dragonflies, beautiful butterflies and their colorful caterpillars, bizarre insects, flies, beetles and even a ‘may fly’ specimen looking quite prehistoric.

The forest is culminating in its green coat refreshed by spectacular flowers of the most bizarre shapes and structures, opening after a couple rain storms, the first just before Christmas and in the first week of January, each yielding about 20 mm. Days have been pretty hot here with maximum of 39°C and up to 70% humidity, so we like to spend our lunch breaks at what we call ‘a la plague’ (on the ‘beach’ of the lake Ranobe) in a shadow of graceful bananas. Since the beginning of January we have a very good track of weather measurements logged by our meteorological station; great tool for long term monitoring of climatic changes.

Trees in our two full-to-capacity nurseries are doing well. New species are germinating continuously and we have been monitoring their growth each month. Replanted trees have each gotten their unique tags for long-term monitoring. FIMPAHARA receives introductions to plant growth monitoring. Ho avy together with FIMPAHARA is finding local solutions to upcoming issues such as nutrient balance and plant survival. We have been supplying the saplings with compost tea, with a solution of local natural insecticides: the soaked bark of katrafay (Cedrelopsis grevei and soaked crushed leaves of neem, Azedirachta indica), keeping the insect herbivores off and strengthening the health of the seedlings; this is part of our nursery maintenance lessons we have engaged FIMPAHARA into.

Creating sunken vegetable beds

Our third nursery’s construction has just been completed we have been filling it up with pots rapidly. It is an extensive nursery, 4m wide and 16m long, with a capacity of more than 6000 pots. At the moment we have 4000 pots waiting for planting in just a few days and we are continuously filling new pots. We anticipate the seed planting will be finished by the end of January – when we will be up to 10,000 pots with growing native plants. This is certainly exciting progress. The children are a dynamic component in that progress; they have been engaged in pot filling and cheerfully carrying bags on their heads. One boy has carried a pot filled with soil on his nose; laughing when we called him ‘mifioky’ (which is the vernacular name for the endemic ephemeral chameleon Furcifer labordi – meaning the one with long nose who can whistle). We have been designing the third nursery to combine natives, food and medicinal plants, using the full potential of the nursery and proximity to the agricultural field for future tree transplanting to agroforestry schemes.

Last Sunday we had an important meeting in the village, during which FIMAPAHRA and ho avy organized a guided tour through the three nurseries, potato cropped land, our two new completed biogas installments, of which the first one has started to produce biogas already, just after two weeks. This is certainly one exciting alternative to the local cooking options – that being open fire and charcoal from the endemic forest wood. One night, returning from the nursery after the sunset, Ondra, our biogas technician grabbed our attention and whispers "come over… I’ll show you something." Taking us to the biogas storage tank, he lit the burner and … a powerful blue flame lightened up the scene. We have natural gas! It’s methane produced by anaerobic fermentation from zebo dung and water.

The villagers were impressed by the flame, and with the fact this may reduce the amount of wood they burn to cook their daily rice. More than 75 members of the community, the local land and land management association (GELOSE), local forest service (SAGE), WWF, the inter-communal association MITOIMAFI, ho avy and FIMPAHARA have gathered to carry discussion on forest protection and sustainable use within the new protected area being finally zoned. All the involved parties have officially approved patrolling against further wood cutting and charcoal making and assist ecological restoration within an area of up to one thousand hectares behind the nursery. This is certainly an incredible step forward with the prospect of sustainable conservation of the unique spiny forest in Southwest Madagascar. We are currently drafting and discussing further agreements between individual parties and discussing the local land policy (dina) for protection and enforcement. The next couple months will be an exciting time to get these documents finalized and implemented.

Along with the nursery works many activities have been carried on in the village through the interactions of ho avy and FIMPAHARA: an effective wood burning mud stove built by ho avy as demonstration has been already replicated in the seasonal home at rice fields, a new well with natural and effective filtering system put in place, language exchange has become popular and we have finally started and are highly energized for building our reforestation center which will be developed over the next month.

Well building

Before…

On November 15th, a group of relative strangers gathered on the dry, red dirt of Moloka’i with the same question firing in their minds. How will we create permanent agriculture on this parched, eroded acre of red dust?

Once the proper introductions were made, our fearless leader, instructor Andrew Jones faced the burning question head-on. Both class and client got a quick review of the Permaculture design process before heading out for a site tour. Site conditions (minimal rainfall, soil erosion, landscape slope) and the challenges of a bustling axis deer super-highway bisecting the property were observed then discussed.

The next day’s visit to Perma-farmer Joe Kennedy’s 25 acres provided numerous examples of effective dry land systems. Dragonflies and bees bustled around the shady ponds he created, in sharp contrast to the neighboring expanse of Monsanto-land. We reaped many benefits from Joe’s 20 plus years of dedication to sustainable agriculture, the tastiest being the bucket-loads of produce we harvested from his farm (Sri-Lankan & cholesterol spinach, pomegranates, tropical almond papayas, 2 types of bananas and more).

In the afternoon we focused on water-harvesting techniques and a Baja case study involving heavy swale work. Then we got down to the business of constructing our swale survey tools (A-frame & bunyip) for measuring the contour lines for flagging the initial swale.

The next morning, we reviewed the design for the project and discussed additions including; deer exclusion strategies, water storage and expanding the potential plant species selection. A bustling axis deer super-highway means anywhere from 15-60 deer cruising directly through the site, everyday, looking for grinds. After much discussion, we decided to start planting areas closer to the house, and seeding the outer zones. Later in the week, a visit to the neighbor’s property would inspire us to try their solution to the crop-grinding deer problem; a tall thorny kiawe fence built from abundant on-site kiawe. It was a beautiful example of art in function. The sun-bleached wall of thorny bones, reaching out to protect its green charge. Less than a week after the course was finished, the clients built their own.

After lunch that day, we marked out the remaining swales and designed the kitchen garden using existing materials (relocating heavy planter boxes from the deer roadside rest stop to a space nearest to the well-used kitchen).

The following morning we were up before the sun, and fortunate enough to watch it light up Moloka’i from a friend’s sailboat as we cruised to the outer reef. An hour of snorkeling gave us a chance to appreciate Moloka’i’s blue underworld.

On our way back from the harbor, we contacted four potential earthmovers to carve our swales. We ended up finding Uncle Ray. Not only did we get the island’s best, we got two loads of mulch (free from dump) delivered before the sun went down. We investigated the piping system for grey and black water, working out the diversion of grey water from the leach field to the banana circle. If you’re gonna shower, you might was well grow some food. Wash your hands, water your taro.

After breakfast we were greeted by Uncle Ray, Penny and their heavy machinery. Once they fixed the driveway, they began fixing the site. Two consecutive “banana circles” or mulch gardens in the shape of a figure 8 and the lower swale and part of the second were dug. The swales were mulched and the greywater was re-directed to the mulch gardens. After we investigated the existing irrigation system layout, we walked over to the neighbor’s house in the golden light, waiting for the “green flash” to see their beautiful gardens and meet their magnificent fence.

The next day, at 7:00 am, Uncle Ray and Penny were at it again, completing the second and third swales. From Farmer Joe’s, we collected plant keikis (banana, taro, sweet potato). We rounded the deep pits dug for our “banana circles” and reinforced their outer walls with rocks found onsite. We mulched the pits with waste materials gathered from the site and stomped them down doing our little “danse composte” as we layered in dump mulch. After filling them to three feet above ground level, we watered down our giant stone-lined figure 8 to give the composting process a proper start. After planting the first of the circles with bananas, sweet potatoes and squash, we gave her another drink.

The final day of class was a busy and emotional one. We finished the top and final (or so we thought) swale, collected aged manure from a local paniolo for the kitchen garden, gathered and prepared additional wild-gathered seed for swales, harvested and diluted ocean water for the pre-existing fruit trees and the keikis in our crazy 8. After the course was wrapped up and evaluations were collected, it was so hard to leave this incredible group that instructors and faculty (Andrew, Nichole and I) almost missed our flight home to the Big Island. My last look at those four giant sleeping swales, snaking across the site, filled me with such joy and hope, hope for rain. Most of the students and the clients stayed on to tour Robin and Dano’s world-renowned perma-farm on the East side and get more plants and seeds into the quickly rehabilitating soil onsite.

After the students left, the work continued. First, our inspired clients took it upon themselves to build their own Kiawe fence. Then, ironically, the night the first big rains came in, their good friends, Robin and Dano happened to be at their home just in time to witness the swales fill to the top. The fab four put their heads together and calculated that, from those rains, 75,000 gallons of water was held in the ground instead of being dumped into the ocean where it chokes out the reef with eroded soil.

After the rain, the clients carefully observed the evolution of the swales and made necessary adjustments. They found mushrooms in their swales, a clear indicator of moisture retention. By observing the way the rainwater charged through the swales, they also determined that a fifth swale was needed. So they gave Uncle Ray a call, and got it done. This work was done only a month ago, working with what we had, using local resources – all chemical free. Looks like Permanent Agriculture to me.

One month later…

I’ve learned that Permaculture courses are often more than educational experiences designed to promote sustainable living. When people from varying backgrounds and generations tune their minds and actions into the harmony of a shared goal, a truly moving lesson in human-potential is learned. The teachers, students, clients, locals, contractors, faculty, family, friends and neighbors involved create a great human exchange. In the sprit of such flawless cooperation, we reshaped the earth to position it in time for Molokai’s allusive rainy season. Our clients are comforted in knowing they are now catching and keeping their topsoil. When our minds are focused and our actions are supported, we can move the Earth in beautiful ways.

On that note, I offer my heart-felt thanks to the following people for making this great work possible. To our clients, for their endless support and hospitality. To Farmer Joe for his generous supply of greens and keiki plants. To Angel Frau and her whirling dust devil of a husband for their utter joy of life. To Ali’i Tasi for her great love and dedication to Hawaii and her people. Mahalos to Auntie Bertha, what an honor to meet such a vital and gifted member of the community. To Uncle Ray and Penny for artfully moving the earth to heal the damage done by years of erosion. To Spurdy for having the intelligence and courage to clean (and mop!) the kitchen of the crowded house wearing only an expertly tied sarong. Thank you Nichole and Andrew for mastering the delicate balance of structure and chaos necessary to obtain true knowledge. To the up-and-comers, the bright and ambitious ones who have a lot of work ahead of them; Hunter, Rob, Eric and Laura, thanks for giving a damn and having the courage to do something about it. Mahalo Nui to Uncle Billy. On a magical night at Hotel Moloka’i, his words set the tempo for this great human experience. “You always gotta come from da heart, and Molokai is from da heart”. Good words to live by.

I’m forever inspired by this outstanding group of characters, and I eagerly wait to roll up my sleeves with the next class. At this moment, strangers from strange places unknowingly wait to become life-long friends. Judging by the momentum created from the connections made, I won’t be waiting long. Check the website for up-coming Moloka’i and greater Hawaii courses. Aloha and a hui ho.

* Our hosts/clients Roshani and John Nash wished to be named in the article. Their support and passion for Permaculture was key to getting this important work done. The fifth swale wasn’t done by Uncle Ray, they in-fact hand dug it.

It’s taken a while to find the time to sit down and report on Part B of our earthworks here at Rosella Waters, near Cairns in far North Queensland. Phase I Part A was documented whilst the process was taking place. This latest update however will rely on memory and hurried notes made during the process, together with numerous photos. Large excavations such as the two large dams we constructed in part A are considerably easier to direct and far less time consuming than the finer detail work using smaller machinery as we experienced in putting in Part B.

Once again we had an excellent earthmover that came on the recommendation of the guys who did the two large dams. Sparky, as he is known, is a very knowledgeable and experienced earthmover, having spent a great deal of the last 40 odd years driving a 46 tonne excavator, building large scale dams, roads and “opening up new country”, as the saying round here goes. Now he runs a private earthmoving business and has at his disposal an 85HP bobcat and a 4 tonne mini excavator with numerous attachments. All of the following work was done with these two small machines.

The first part of the process in Part B was to construct a gabion rock wall at the very top of our system, in the gully that feeds our two dams. Previously, we had done a catchment analysis and based on the 1000mm of rain we receive per year, we arrived at a figure of 5,000,000 liters moving through it. We used this figure to calculate levels and engineer our spillways, level sill heights, the freeboard on the dam walls, trickle pipes, lock pipes, etc. The gully in question begins on our neighbour’s property. It is fed from the hill behind it and also from the diversion drains the road department puts in on the dirt road leading to our front gate. The catchment is predominately regrowth after being cleared 30 years ago with two dozers and a ball and chain. The catchment area is not a well functioning bio-diverse eco system and as such there is little water infiltration and a lot of sheet flow that brings top soil/sediment run off into our system. During the wet season of 2008 we did a small trial by hand building a rock wall just inside our fence line to get an idea of how much material would be trapped and how long it would take to fill up. After only 3 rain events, the small rock wall was fully backed up with silt 1.5 feet deep and the moisture remained just under the surface of that material well into our dry season. With that experience and the slight scar constructed at the back of the Lap Pool dam during its construction, we decided on a larger than first thought gabion, to (a) repair the damage caused by the construction of the Lap Pool dam (b) trap silt/top soil and sediment, preventing it washing through our system and ultimately ending up on the Great Barrier Reef, and (c) provide a small scale example of a solution to dry eroded gullies, that run like rivers in the wet, utilizing a “waste” product of local agriculture.

The “waste” product I speak of are the mountains of volcanic rock that many farms in the area have piled up in massive windrows. Farmers spend up to $4000 an acre to pull them out in preparation for planting avocados, potatoes, mangoes, bananas, sugar cane, etc. Rosella Waters sits right on the edge on an ancient lava flow so the farms that surround us are littered with such rocks, some as large as a car down to rocks as small as a grapefruit. We approached our neighbours up the top of the hill, who grow avocados and mangos, and who had recently put in a mass planting of new trees. Prior to that they had a 20 tonne excavator and dump truck working for a week to pull every rock out. They followed this by traversing over the land with a pickup and five workers pulling the grapefruit sized ones out by hand. Anyway, they were more than happy for us to go onto their property and select as many rocks as we liked from the windrows, which they had conveniently separated into different sizes.

Gabion rock wall trapping silt/sediment & top soil

The cost in building the gabion was therefore the time for Sparky to load up the individually selected rocks into his tip truck and then place them one by one with a claw on the end of his excavator arm. The process took two days in total and we estimate that it cost us close to $1800 to build. As we had large rocks to work with we decided against both “keying in” the base of the gabion wall into the side of the gully and constructing a net meshing to encase them in.

The volume and more importantly the velocity of the water coming down the gully in this case didn’t necessitate us doing either. Choosing the largest rocks first, we placed each one exactly where we wanted to create a firm base on which to construct the wall. It was built much in the same way as a dam wall is built, starting out wide at the base, six meters in this case, and tapering up to two meters wide at the top. The height of the gabion is nearly three meters. After placing each rock, Sparky would firm it down, swivel it around until it was firmly wedged. This in itself is more difficult than it might seem and does take time, but it is VERY important to get right. In all, the wall required 7 full dump truck loads of rock to construct. Once the main frame of the wall was complete we got another two loads of grapefruit sized rock which we have since placed by hand to smooth out the top of the gabion, thus providing a great access path across the gully that we can push a wheel barrow across, drive an ATV over or lead a goat and cart. To repair the scars at the side of the back of the Lap Pool Dam, just in front of the gabion wall, we placed some large rocks on the ledge and back filled behind the rocks with some top soil we had had set aside from the construction of the two dams. This was immediately cover cropped with cowpea and a crotalaria variety called gambia pea. All of the seed we used to cover crop was bought from a local seed merchant as seconds, which means there is a low strike rate (around 40%) but at $1 per kilo and having used the correct inoculant, we gained excellent coverage and stabilized the area. It’s important to remember that seed is the cheapest herbicide!

The next element we tackled was the overflow swale and spillway connected to the larger Mushroom Dam at the bottom of the property. We decided that after completing the gabion it would be best to start at the bottom of the system and then work our way back towards the front gate so that by the time it was all done, Sparky could load up and head off without risk of doing any damage with his machinery.

The first swale was only fifteen odd meters in length and had a level sill spillway half way along it that would spread the overflow of the system over a 3 meter wide area right on a broad ridge point, making it very safe to discharge and presenting no danger of causing an erosion gully. The construction of this small element proved to be a major turning point in our working relationship with Sparky. In the end it took the best part of a day to complete, due to a number of factors including our newfound language barrier. There were some important miscommunicated terms that needed clarification as we went: level sill spillway, back cut, swale, swale mound, swale dish, bottom of the swale dish and most importantly LEVEL. The idea that we wanted to construct something that didn’t run and was in fact perfectly level and on contour was quite a paradigm shift for Sparky, as in his words he had “spent his whole life draining landscapes” and what we wanted to do was quite the opposite.

The swale needed to be constructed on a steepish slope and we decided that we wanted it to hold 300mm of water in the base and have the top of the swale mound 800mm high – thus a substantial 500mm freeboard on the swale mound. The freeboard on the dam wall is one meter, so if ever there was a chance of water spilling over it would go over the swale mound first. It is unlikely to occur as we have “over engineered” things, but if it did the swale mound can be repaired with a shovel unlike the dam wall! What we soon discovered in constructing the swale was that due to the slope of the land we just wouldn’t have enough material to make the swale mound as high as we wished. The answer was to dig further up the hill from the back cut, as gently as possible, in a 1:1 cut. We didn’t want to dig too far up the hill so we adjusted the level of the swale mound back to 700mm high and with a three-meter long level sill spillway, the swale mound still wouldn’t be at risk.

First swale constructed leading off the Mushroom Dam

The data records for the region showed that the largest single 24-hour rain event in the last 30 years had been 284mm. We rounded this out to 300mm and built the spillway to be able to deal with ½ cubic meter of water per second. Together with another spillway on the swale connected to the opposite side of the dam wall, we have more than ensured the dam wall’s safety. Another safety margin we designed into the system was a 110mm lock pipe set at the bottom of the Mushroom Dam wall. The lock pipe is 27 meters long and goes right through the bottom of the wall. On the outlet side there is a butterfly valve, which can be opened wide in the event that the spillways aren’t coping. At the bottom of our system, and being our primary aquaculture dam, it also means we can drain this dam if needed. The dam also faces West, which is likely to be the direction of any fire entering our property, so in the event of a fire we have the added security of being able to drain 2.5 mega liters of water in that direction.

For ease of construction we built this first swale with the 85HP bobcat, equipped with a 1.7 meter wide tilt bucket. Time is money with earthworks, so we decided to make the swales a bucket width wide. Sparky started by running across the slope with his bucket following the back cut line we had marked out, corresponding to the high water mark of the dam. The spill was flicked down slope forming the first part of the swale mound. Once we had the basic shape and marked the position of the level sill spillway, Sparky used his tilt bucket to scrape beyond the back cut line up the slope to get the material we needed to gain the swale mound height we were after. We also took quite a bit of material from the area leading onto the dam wall, progressively cutting back to smooth out the sharpness of the cut. Sparky did a great job and we can easily drive through this area and up and onto the dam wall, giving us access to the other side of the property. The swale runs dead level at 300mm deep all the way through, from the exit point at the dam to the end of the swale itself. On the final scraping run we asked Sparky to tilt the blade slightly down slope in the swale dish, meaning that water will be predominated into the swale mound during rain events. With our first swale complete, fully seeded and earthmover trained we we’re ready to attack the rest of the design. Together with a mix of gambia pea, cow pea and pigeon pea we also planted sweet potato cuttings, aibika, cassava, pumpkin seeds, etc… giving us full cover leading into the wet. In the last few days we have started to receive our first rains in 9 months, so now we have a good base in which to begin our major plantings.

The next swale was a short one connected to the opposite side of the dam wall. It was constructed in the same fashion and care was taken again to ensure a smooth driveway leading off the dam wall for ease of access. With not much room to play with within our boundary line, the swale was extended right up to the fence line with our neighbours and the three-meter level sill spillway will serve as discharge of excess water into the creek below, and also as access to behind the dam wall and our Zone IV area of the property.

Moving further up the slope, we then tackled the 25-meter long swale connected to the Lap Pool dam. With this swale we had a few important decisions to make. Firstly it was going to be the Lap Pool’s only swale and only level sill spillway, the overflow from this leading to the Mushroom dam. The placement of this level sill was therefore vitally important as it would be the major source of water that fills the Mushroom dam and we also have future plans for structures connected to the 6m x 3m jetty we placed on the dam. We saw the opportunity for the level sill to be a feature and a potential wet/dry growing area, in close proximity to the jetty and eventual cabin connected to it. We decided to step the overflow down into a further two level sills before it entered the Mushroom dam.

The step down spillways leading overflow from the Lap Pool Dam swale into the Mushroom Dam. Jetty posts in waiting.

In this way, we slow down the volume of water, create further edge and add an aesthetic feature in the process. The level ditches are slightly wider than the level sill on the swale itself and together with generous amounts of cover crop seed, we planted clumps of vetiver grass to further stabilize the area and slow down water flow. We used the same technique on all the level sill spillways. With such an abundance of rock at hand and a couple of quite steep spillways to stabilize, we saw this as our best option. On two steep spillways, we planted out clumps of vetiver grass across the slope, starting at the top and offset all the way down. Then we placed rocks from the bottom up, starting with larger rocks in an arc, wider than the spillway, followed by smaller rocks all the way up the spillway wall face. We left a 200mm space around each of the vetiver clumps and now 3 months later we have a very stable, rock wall face to our spillways, with large clumps of green vetiver grass breaking up the brown.

Back on the Lap Pool swale we asked Sparky to dig ½ meter deep x 1 meter long x ½ meter wide ditches within the swale dish itself. These ditches will hold water for longer than the rest of the 300mm deep swale and as such become growing zones for some wet crops. We now have these ditches planted out with Taro, with water chestnuts on the edges, all of which is shaded by bananas growing at the inside edge of the swale mound.

Again the whole swale was cover cropped with cowpea, Gambia pea, pigeon pea and dotted with cassava, Aibika, sweet potato and pumpkins. The larger long-term support species and variety of fruit and nut trees are now ready to be planted. We had considered putting all of plantings in at the same time but with no rain at all for close to 9 months we decided to get cover crops and shorter term nitrogen fixers going and wait for the beginning of the first rains before putting them in. The earthworks couldn’t be put back to a more appropriate time due to the availability of machinery.

The rice paddy system was by far the biggest challenge. To look at now, it seems all we have done is push a little dirt up to make a wall and dig a couple of holes for the ducks to live near. In a sense that’s true, but the process of constructing the 1:300 diversion drain from the Lap Pool dam to a duck pond connected to a rice paddy (the overflow of which runs along a diversion drain with a 20mm fall over 20 meters, to another duck pond connected to another rice paddy, the discharge of which drops down into a 25 meter long bio-filter which is itself a level sill spillway), dropping water into the Mushroom dam wasn’t that simple! Plus, the overflow of the second duck pond, leads to a short swale with level spillway that drops down to a 20-meter long swale, the spillway of which also drops into the bio-filter before being discharged into the Mushroom dam. Phew.

The rice paddies with bio-filter below. The beach area is on the edge of the Mushroom Dam with the back side of the Lap Pool Dam wall behind it.

A great deal of gravel road base material was taken out of the rice paddy area and we used this to repair/construct a proper ringed access road, our main access road on the property. The road has now been graded correctly so that water will run into drains leading along side it directed to water storages. On the road we have placed 150mm x 50mm x 4 meter long blue gum planks in sets of two, 4 inches apart, at an angle across the road, every 10-12 meters. We first heard of this idea from Rainbow Valley Farm in New Zealand who has the same system on much steeper roads. As water runs over the road it only has a short distance to run before it drops down into these drains that run across the road at a slight angle. By not allowing the water to build up speed over the road surface the material stays on the road rather than down the bottom of the hill, with obvious benefits.

The diversion drain leading to the 1st duck pond needed to fall at 1:300 and be set low enough in the Lap Pool dam so that it was the first water to leave the dam as it filled. We can regulate this fact by capping the end of the 150mm pipe. The level at which we set the150mm diversion pipe was 450mm below the high water mark of the dam which also corresponds to the level of the level sill spillway. That is 150mm lower than the depth of the swale and the level at which water exits the dam into the swale. As I said, setting the pipe at that level ensures we can control when the water heads to the duck ponds. We have a 30,000 L concrete water tank connected to our shed with approximately 100,000 L of potential roof catchment. We needed to decide what to do with the extra 70,000L. In a minor brain wave, we came up with the idea to pipe the overflow through a 90mm pipe down the side of the tank, under the road and into the 150mm diversion pipe with a t-piece. At the entry point into to first duck pond, we have rocked the spill and next to the 150mm diversion drain pipe we have another 150mm pipe under the road that collects all the water in the drain running alongside the road. At the end of the drain along the side of the road we have dug a meter deep silt trap, concreted the base and placed a grill over the top. This will keep silt out of the duck ponds and provide another source of potting mix from the material that does ultimately come from the road.

The main issue we faced with the levels we were dealing with was to get the duck ponds as high up the slope as we could, leaving us room to put in the proposed rice paddies. The duck ponds would end up being quite small as a result and have a 800mm slope at the back of them from the ridge road. We saw this back slope as another opportunity to be creative and decided to step this down in 300mm wide ledges to the high water level of the ponds. The end result is a duck pond amphitheatre on both ponds! This stepped area will be fully planted out with duck habitat and forage, shading the ponds in the process.

Duck ponds at the back of the paddies, connected by a diversion drain. The amphitheatres at the back of the ponds are well cover cropped and stable.

The two ponds are connected by a diversion drain that runs from 1st pond to 2nd pond, with a 20mm fall over its 20-meter length. This isn’t a great deal of fall, but it’s enough. It has meant we have been able to keep the 2nd pond up as high a possible to give us room for the paddy below. The water from the duck ponds are released into the paddies by way of gates we picked up from an old rice farmer up here. They used to grow two crops a season using the channel that leads from Tinaroo Dam as a source of their water. One of the reasons they gave it up was when the cost of water went from $8 p/ML to $18 p/ML. Now they flood irrigate sugar cane instead. We swapped the four gates for a case of beer and made metal plates that slide into the 3mm gap in the concrete gates, to control the flow of water. The same gates are used at the exit end of the paddies, to discharge the nutrient rich water into the bio-filter below before it heads to the Mushroom dam.

The bio-filter that acts a level sill, taking nutrient rich water from the paddies as well as the swale in the background at the base of the chicken tractor system, overflows into the Mushroom Dam.

The two paddies are separated by a meter wide bund and surrounded by a meter wide, meter high bund with a slight grade. All of this will become a growing zone for duck forage, mulch and some soft fruits such as pawpaw and banana. The meter high bunds, once planted out, will become a living fence keeping the ducks in the paddies during the rice-growing season. We plan to grow rice using the integrated rice and duck growing system I had learnt whilst living with Takao Furuno and his family in Japan. Takao is a social entrepreneur with the world economic forum with his rice duck growing system and has an excellent book out through Tagari publications titled “The Power of Duck”.

The short swale connected to the second duck pond drops down into a longer swale, which will form part of our chicken tractor system. This 20 meter long swale lies at the bottom of the contour chicken runs and borders the Mushroom dam. It’ll take excess nutrients from the chicken system and grow some large trees on the north side of the dam, providing shade. Due to this swale being constructed on less of a slope than the first, it was built with the four tonne excavator. Working from the downward side of the swale, the bucket cut on the back cut line and the spill was dropped to create the swale mound. Following Sparky along with the laser we ensured that the swale dish was 200mm level all along. It doesn’t need to be within a mm but it does help to make the dish as level as possible so as to get an even distribution of water along the swale in lesser rain fall events. Obviously the best way to check that level is to fill the completed swale with water and adjust accordingly with a shovel. It is cheaper to do this in your own time than to pay $100 an hour for a 4 tonne excavator to do it.

“Hairy Harry” stands tall on the island at the back of the Keyhole Dam.

The final element to put in was the Keyhole dam at the entrance to our property. We named this pond the Keyhole, as it is the key to the system that connects water on both sides of the property. The Keyhole sits on a central ridge that dissects the property and the idea was to create a small water storage in our Zone 2 area that can move water through either the system described above or to future water storages on the river side of the property, or both. We decided how large a storage of water we wanted and marked out the approximate position of the dam wall for Sparky to follow. We set a target level for our high water and corresponded this to the position of the two swales that were to direct water to the Keyhole via 150mm pipes placed under the access road. The wall was built using the bobcat, layering wetted clay followed by numerous track rolls with the same machine. Using the excavator to dig the hole of the dam, material was mixed using the tilt bucket with me standing close by, hose in hand, making sure there was the right amount of moisture to make the clay bond. Dam and pond walls are all about compaction and with enough of the right clay, a little mixing if the material is good and bad, and the correct amount of moisture, things should seal. We decided to create a small island at the back of the Keyhole as an aesthetic feature, duck habitat and for the fact that the palm we’ve named “Hairy Harry” was too good looking to lose.

Once the Keyhole was built with a 400mm freeboard on it, we set about marking the back cuts of the two swales that were to connect to it. The Mediterranean swale (so named due to quite granite soils in that part of the property) leads out towards the header tank and drops its spill down into the Lap Pool dam. It is connected to the Keyhole via a 150mm pipe, under the road with a slight 20mm drop towards the pond so as to not get stagnant water sitting in the pipe.

The Mediterranean swale connects to the Keyhole Dam via a 150mm pipe under the main access road. The level sill spills water into the Lap Pool Dam below.

The end of the pipe can be capped, if we wish to keep water in the Keyhole dam and direct any overflow via the 150mm pipe under the road on the other side that connects the Council swale to the same dam. We called that one the Council swale because its main catchment comes from a slight improvement to the dirt road the council recently graded. It was graded sloping towards our fence with no drain so in large rain events we would get large sheet flows of water moving through the landscape causing unnecessary erosion. We asked Sparky if he wouldn’t mind creating a little spoon drain 100 meters up to the neighbours gate entrance and directing that water through the culvert under our road entrance. The five meters beyond the culvert to our fence line continued as a drain before entering our property where it then becomes a level swale directing a substantial volume of water through the 150mm pipe, under the road, into the Keyhole dam and ultimately through our entire system.

Considering the volume of material we are likely to receive from the dirt road, we placed a 200mm deep x three-meter wide silt trap just inside the fence line. This can be dug out by hand when necessary. The level sill spillway of this Council swale directs overflow to a gully, which in future may become a dam or a large gabion, subject to future test holes to check for clay content.
Either pipe in either swale can be capped to control the direction of water movement through our system. This small dam feature is something we are really happy with for its aesthetic beauty and complex simplicity in functionality.

This spoon drain runs 100 meters long and will direct a large amount of water through our system via the Council swale that connects the Keyhole Dam.

For our first major earthworks the complexity involved in the design was substantial. It was quite a big undertaking, made even more so by the birth of our second son Dylan smack bang in the middle of it all. At this point I must give special recognition to my darling wife Georgie who at 41 weeks pregnant, kept us fed and watered, took all the photos and spent considerable time standing there with FRED ( Forever Ridiculous Electronic Device) i.e. the lazer level staff and receiver, in 33′C tropical heat. We took close to a year observing the site, designing, listening and talking to others, re-designing and planning the earthworks and the immediate repair work after they’re done. Once the earthworks began, concept became reality and the two can be quite different no matter how good the planning. Each evening after Sparky had left we spent time talking things over and making decisions for the next day’s work. We gave our laser level a really good working over, it has been a great investment; I don’t imagine we could have done all that we did without it.

Now that the mainframe infrastructure is in place, a little water is in the dams and the site is green with cover crops, the system has literally come alive. From seemingly nowhere frogs have descended upon the water storages attracting ever-increasing numbers of birds. The place must look like a red-light sale at a discount store – a hydrated green oasis in an otherwise dry landscape.

Overlooking the system from the header tank. A transformed landscape.

A natural spring we knew existed has started to recharge with the water in the swales from irrigating the cover crops. It moves through the sub-soil leaking out into the side of the dam. Our hope is that this recharged system will help to keep the water level more constant in the Mushroom dam by offsetting any evaporation.

In all, the earthworks took close to two months to complete from start to finish with a total of 16 days of actual earthworks involved. With the start of our seasonal wet season rains upon us, the next three months or more will be spent busily planting, planting and more planting. We know Sparky is coming back when the wet really hits – we made a pact to sit down with a beer together in the pouring rain and watch the system operate in full flight. Through a local NRM group we are also planning an open day, for local farmers to come and see the system. These major earthworks are just the start of a great adventure in the development of our Permaculture demonstration site for the wet/dry tropics of Northern Australia, Rosella Waters.

The partially completed swale is about to be extended.
The drain is near my right foot.

My latest project is a 25 square metre vegetable patch in subtropical Narangba, South East Queensland, Australia. I could choose the site, and although it wasn’t exactly ‘zone 1’, I settled on an area adjacent to the neighbour’s fence. The soil and solar access are good, and the adjacent fence reduced the amount of additional fencing needed to keep out the dogs, the most expensive purchase for the garden. Being out of the way was an advantage because the owners were not completely sold on having a vegetable patch. I was also hoping that the activity would encourage the neighbour to resurrect their neglected vegetable garden, and they did come out to enquire while the garden was being installed. There is hope.

These are all great qualities, but the main attraction was a downpipe from the house that drained onto the lawn. I could catch the water and distribute it along the length of the garden. Even a light shower would contribute. I have observed that apparently heavy showers can fail to penetrate more than a couple of inches of mulch, so I believe getting the water into the soil is important. I marked out the contour, used that as the upper boundary, and dug the swale trough about 20-25cm wide. I also put a few pavers in front of the drain to prevent erosion of the mound if the water came out in a gush. On the first day I did not get around to installing an overflow, and as it happened there was a storm the day after. The swale filled as predicted, but the water overflowed and flooded part of the garden, partly washing out the path.

The drain is at the bottom left, obscured by grass and pigeon pea.
The pavers for erosion prevention and flow restriction are visible.

The next task was to extend the swale away from the garden with a level sill spillway, as done in Geoff’s Harvesting Water DVD, so that the garden wouldn’t be flooded and it would release water gently onto the lawn. It took some time for me to observe this happening. In the meanwhile I heard that the extension was a little lower than the garden section – it was getting small downpours instead of the garden. Even if I leveled it properly the water could be wasted on the lawn. I placed another paver as a dam to the extension. On Christmas day I got to see it in action. The water didn’t gush, but the drain has since been cleaned so it could happen yet. The original garden section of the swale filled up and the paver slowed the water enough to direct it to the garden first. The mulch and absorption in the swale slowed the advance of the water as it moved through, so even with the paver the extension was getting some early water. While the swale was filling up, the water level on the garden side was higher. The spillway worked as designed when full, letting the water cascade down hill.

The swale is full and overflowing via the level sill spillway.

Further observation revealed that during heavy downpours, there was perhaps too much water in the garden. I had not noticed that the driveway and the neighbour’s driveway could feed the swale too. This explains the good soil, as the area is like a fertile valley, collecting water and sediment which is slowed by the grass and absorbed. After extended rains, the water was springing out of the garden and onto the path! A hole made for planting would fill up with water! To make use of this excess water, I’m considering installing another swale further up the hill, wide and shallow to prevent impeding vehicle access to the back yard. This should charge the soil above the first swale, providing a reserve for when the weather dries out.

The garden was a popular attraction on Christmas day. On the left you can see

the bean trellis, prayer flags and escaping pumpkin.

The garden, while it has some gaps in the planting, has so far been a success with only a few disappointments. There has been a constant supply of lettuce, zucchinis, cucumbers, and now some corn. The garden has pests but the predators seem to be keeping them in check after only 2 months. A 1kg zucchini was just harvested, there is a sunflower I can’t reach the top of, and the owners are talking about expansion!

Much more beautiful than lawn!

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.

The proposal originated with Frank J. Popper and Deborah Popper, who argued in a 1987 essay (PDF) that the current use of the drier parts of the plains for agriculture is not sustainable. The authors viewed the historic European-American settlement of the Plains States as hampered by lack of understanding of the ecology and an example of the "Tragedy of the Commons". Many people in potentially affected states resisted the concept during the 1990s:

There once were over 400 million acres of wild prairie grasslands in the central part of North America. The backbone of the Buffalo Commons movement is the work — over a period of decades — to re-establish and re-connect prairie wildland reserves and ecological corridors large enough for bison and all other native prairie wildlife to survive and roam freely, over great, connected distances, while simultaneously restoring the health and sustainability of our communities wherever possible so that both land and people may prosper for a very long time. Future generations may choose to expand these reserves and corridors, as the new culture of caring and belonging we have started today becomes an integral, ingrained part of life in the world of tomorrow, especially as extensive grasslands become needed to help absorb carbon from the atmosphere. (Highly biodiverse native prairies are excellent carbon sequesters.) – Buffalo Commons

It’s fascinating material and an idea worth entertaining, to say the least. The Poppers propose that a significant portion of the region be gradually shifted from farming and ranching use. They envision an area of native grassland, of perhaps 10 or 20 million acres (40,000 or 80,000 km²) in size.

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.

Yeomans’ methods, which have heavily influenced permaculture design systems, are increasingly seen today as having tremendous potential to not only increase agricultural productivity but also to have a significant impact on reducing atmospheric CO2 concentrations through increasing soil carbon levels.

It’s a sad day when such a site, with not only such historical significance, but also present relevance, would be paved over.

For good measure, here’s a YouTube clip of Darren Doherty showing the before and after effect of a single keyline plowing on his property.

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.

A little background on the video follows:

When there’s no soil, no water, no shade, and where the sun beats down on you to the tune of over 50°C (122°F), the word ‘poverty’ begins to take on a whole new meaning. It is distinct and surreal. It’s a land of dust, flies, intense heat and almost complete dependency on supply lines outside of ones control. This is the remains of what was once called the ‘fertile crescent’. It is the result of thousands of years of abuse. It is a glimpse at a world where the environment – whose services provide for all human need – has all but completely abandoned us. This is a glimpse at the world our consumer society is inexorably moving towards, as our exponential-growth culture gorges itself at ever-increasing rates.

The original Greening the Desert video clip has been watched hundreds of thousands of times and has been posted to countless blogs and web pages in the datasphere. Although only five minutes long, it has inspired people around the globe, daring the lucid ones amongst us, those who can see the writing on the wall, to begin to hope and believe in an abundant future – a future where our survival doesn’t have to be based on undermining and depleting the very resources of soil, water, phosphorus, etc. that we depend on. The work profiled in that clip demonstrates that humanity can be a positive element within the biosphere. Man doesn’t have to destroy. Man can repair.

In the clip at top I introduce you today to Greening the Desert II. I shot the footage for this video last month (October 2009) and edited it on location in the Dead Sea Valley in Jordan – the lowest place on earth, at 400 metres below sea level. Much of it was shot in or near the village of Al Jawfa where I stayed, which is effectively a Palestinian refugee camp that has morphed over the decades since 1948 into something resembling a functional small town. It was first shown to delegates of the ninth International Permaculture Conference (IPC9) in Malawi, Africa at the very beginning of November and is now being released for general consumption. The video will take you to the original Greening the Desert site, letting you see its present condition after six years of neglect when funding ran out in 2003. You’ll also be introduced to our new project site – the Jordan Valley Permaculture Project, aka ‘Greening the Desert, the Sequel’ – and see some of the spin-off effects within Jordan from the influence of the original site; promises of much more to come.

The work we’re undertaking in Jordan is in accordance with what we call the ‘Permaculture Master Plan‘, where the project’s future is assured through funding from running educational courses. Project sites thus become self-sufficient, and self-replicating.

Through this work we envision thousands of educational demonstration sites worldwide – all inspiring and teaching communities around them how to begin to tackle at root the massive challenges we now face after decades of short-term profit-based thinking has all but ‘consumed’ our planet and dismantled the social constructs that the human race has always depended on for its survival. Through this work we see desertification stopped in its tracks, and reversed. We see this century’s dire water issues getting resolved. We see productive work for millions in bypassing the irrelevant efforts of our ‘leaders’, to instead build a new kind of culture – a culture based on cooperative effort and learning. It’s a culture where its members have regained a sense of their place in creation, where they become land-based stewards of remaining resources; creating a culture where we at last find ultimate satisfaction – promoting and building peace and low-carbon, relocalised, community-based prosperity.

We have many such ‘Master Plan’ projects in various stages of development worldwide, and a steady stream of enquiries from people around the globe wanting to get involved and help widen this cooperative network. Perhaps it’s time you took a look at Permaculture? After all, do you have something more worthwhile to do?
