A certain coal-strewn road in Madrid, New Mexico
— the remnants of a now defunct railway.

Alternately barren and spectacular, the southwest United States has piqued the imagination of Americans and people across the world for generations. The site of gold rushes, Native American homelands, and a culture of lawlessness that has yet to fade completely, much of the land was degraded and destroyed long before Hollywood discovered how to cash in on retelling stories from its checkered past. Films may glorify the breadth and scope of the iconic terrain, but the essence and character of the Southwest ecology has been drastically altered; it little resembles what it once was.

Urine: Closing the NPK Loop

Conservation, Rehabilitation, Waste Systems & Recycling, Waste Water — by Mark Feineigle November 27, 2011

The Stockholm Environment Institute conducted experiments and collected data that shows the usefulness of a resource every one of us has access to — urine. When utilized as a fertilizer, urine can provide an alternative to chemical fertilizers. The impacts ripple far beyond the nutrient value of the urine; in developing regions, diverting a urine waste stream to fertilizer has a significant economic value. These benefits can easily be recognized at the individual level, and scale all the way up to industrial operations.

An aerial view of the site

Although the landscape here could be seen as a model for scarcity, what there is an abundance of is rocks. The baked dusty earth barely passes for soil and during the summer there isn’t rain here for over six months. With valuable agricultural resources seemingly at a minimum, rocks can be incredibly valuable in the design of a sustainable human settlement. In the case of the Permaculture Research Institute of Jordan’s site (PRIJ), rocks have formed the main building blocks of the swales that form the back bones of this small farm. They surround the heavily mulched planting pits for the many varieties of trees here and they also can be used for another useful function which litres of my sweat has been testament to! They make up the substrate of the grey water system into which reeds are planted that feed on the water flowing through from the sinks and showers in the washing block.

In northern Jordan during the summer of 2009, I was on a mission to document a modern-day Roman-era cistern resurgence. I met with Engineer and Permaculture Project Manager Sameeh Al-Nuimat at the Care International office outside Amman. He was great. He has rural hardworking roots, loves native plants and traditional ways, is very enthusiastic and knowledgeable about whole-system design, and decided we’d begin the day by having an Arabic breakfast with everyone in the office. We all grouped around a very small, low table piled high with hummus, pita, olives, falafel etc, and ate with our hands. What a wonderful way to bring everyone together as the day begins!

A Tale of Two Tokyos – Domestic Robots and Permaculture Bathrooms

Biological Cleaning, Building, Conservation, Urban Projects, Waste Water, Water Harvesting — by Cecilia Macaulay August 3, 2011

Written a year ago by Cecilia Macaulay


Robot and charcoal-fired tea ceremony brazier

Roving, roving. I’m now staying in Central Tokyo, at my usual home with the Ota family.

This morning I reached for the broom, I got a surprise. Professor Ota came running out "No No!"

He bent down, fiddled with something on the floor, and out it sprang — the floor-sweeping robot.

Strawberry Fields Eco Lodge Update: Solar Powered Fridge

Aid Projects, Community Projects, Courses/Workshops, Demonstration Sites, Education Centres, Energy Systems, Land, Processing & Food Preservation, Waste Systems & Recycling, Waste Water — by Alex McCausland April 1, 2011

Editor’s Note: As many of you will have noticed, Alex has been making some great practical updates on the work going on at the Strawberry Fields Eco-Lodge. The following article is another good example. I thought I’d mention that if you want to soak in some excellent experience at this site, Steve Cran will be leading a great course beginning July 1, 2011 that you might want to attend if you can.


The heat chimney for the solar fridge

The solar fridge is a new system which we have now managed to get set up after months of pondering, trying, adjusting, tweaking and trying again. We think we have finally got it kicking and pretty well integrated into the other functions of the kitchen area, so we can demonstrate permaculture principals with it pretty nicely.

The system is based on an old design for desert/dry-land cool storages which makes use of a heat chimney to create an up-draft which then sucks cool air in to the storage chamber from below. This air may pass through a long tunnel in its way to the storage chamber and hence be cooled by the ground on the way to the chamber. In order to enhance the cooling of the air on the way to the chamber, if possible, water, by evaporating will take in thermal energy, causing the temperature of the air to fall further. The main logistical issue to deal with, as usual, in building the system, was getting the theory to work in practice using available materials. Most of the construction work on this project was done by one of our long term volunteers, Duncan Colquin from Herefordshire, England, so a big thanks to him.

Pit-falls, projects and laughs from our permaculture journey – Part 5

“What’s that smell?” asks Chris.

“I don’t know. It’s really familiar. It smells like… cat food,” I reply.

“It smells like shit,” he says.

Editor’s Note: This article was written in mid-December, when Queensland’s rains were nothing like that witnessed of late, and which have caused the catastrophic flooding in many towns and cities across the state. I mention this to ensure people realise Nicola was not being insensitive with timing of a Queensland- and water-based article. Our thoughts go out to all who have suffered in the recent deluges.

Pit-falls, projects and laughs from our Permaculture journey


If women knew diggers looked this good I think swales would pop up like weeds
around the globe. Gee whiz. Beats a four-tonne excavator in my books
– even if it had a swivel bucket.

Chris woke up the other day and declared, “I think I can dig those swales by hand.”

“Super,” I said, “go for it!”

Compost Power Hot Shower Report, Ethiopia

Aid Projects, Commercial Farm Projects, Community Projects, Compost, Conservation, Demonstration Sites, Education Centres, Energy Systems, Rehabilitation, Waste Systems & Recycling, Waste Water, Water Harvesting — by Alex McCausland December 18, 2010

We recently submitted a short report on our hot-fast-composting system, which gave some detail on the theory and practice of producing compost in as short a time as 21 days. But Permaculture principals tell us that we should always be looking to yield as many useful products and functions from any process or element as possible and it is obvious that one bi-product of hot-composting is heat. If you get it really right, a heap should reach 80°C, which is literally too hot to touch. Feeling is believing. Once we were getting to that stage with our compost competency I began pondering how we could effectively catch and store some of that heat so that it can be used for a hot shower.

I finally realised that lots of mucking about with coils and heat exchange loops, lagging and insulation etc. could be avoided if we simply have the hot water tank inside the compost heap. Jean Pain, the old French Roi de Compost did something like this in his place, but took it a lot further, even to the point of having a biogas digester inside a cooling jacket inside a giant compost heap. He was able to heat his house and get compost and biogas all out of the one system. Ours is simpler, but the good thing about that is that you don’t have to be a practical genius to do it.

Piped Swale Crossings

Conservation, Earth Banks, Irrigation, Land, Soil Conservation, Storm Water, Swales, Waste Water, Water Harvesting — by Geoff Lawton November 13, 2010

Permaculture is a connecting system between disciplines and elements in a matrix of design, and swales are a mainframe element. The efficiency of swales is that they can interrupt water surface flow high in a landscape where it is then infiltrated relatively quickly, on contour, and moves incredibly slowly through the landscape soil and subsoil profiles. This becomes a great advantage to the potential productivity of any property, especially a property that is designed to be diverse and interactive with many ecosystem elements. When you design a property this way, a mainframe approach as a consultant designer is:

Reducing Urban Water Use

Biological Cleaning, Compost, Conservation, Potable Water, Rehabilitation, Soil Conservation, Soil Erosion & Contamination, Storm Water, Waste Systems & Recycling, Waste Water, Water Contaminaton & Loss — by Earth Policy Institute November 4, 2010

by Lester R. Brown, Earth Policy Institute

U.S. President Theodore Roosevelt once noted that "civilized people ought to know how to dispose of the sewage in some other way than putting it into the drinking water."

The one-time use of water to disperse human and industrial wastes is an outmoded practice, made obsolete by new technologies and water shortages. Yet it is still common around much of the world. Water enters a city, becomes contaminated with human and industrial wastes, and leaves the city dangerously polluted. Toxic industrial wastes discharged into rivers and lakes or into wells also permeate aquifers, making water—both surface and underground—unsafe for drinking.

How to Handle Biomass in Dry Tropical Systems: Mulch Pit Gardens

Biological Cleaning, Compost, Courses/Workshops, Food Plants - Perennial, Fungi, Irrigation, Land, Plant Systems, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Structure, Waste Systems & Recycling, Waste Water, Water Harvesting — by Andrew Jones October 29, 2010

The dry tropics cover a significant land area of the planet, particularly around the regions of the tropics of Cancer and Capricorn. Characterized by a majority of the year when evaporation potential is greater than rainfall, they also support rapid biomass growth during and following the rainy season. Legume species normally form a significant portion of the species present, and provide for rapid biomass production.

Management of this biomass can be tricky, particularly when left above ground in dry mulch piles, as it normally stays dry, inhibiting both fungal and bacterial breakdown. On the flip side, dry tropics soils, whether sandy or clay-based are in need of organic matter to balance structure, enhance water retention or drainage and build humus. One approach for creating such conditions are mulch pit gardens.

Papaya, banana, and coconut circles are developed by digging pits up to two meters in diameter (for papaya or banana – up to three meters for coconuts) and about 1 meter deep. These are then filled with dampened, compacted organic material to a height of 1 meter above ground. Up to seven plants of the appropriate type are then planted in the rim of the pit. Taro or other moisture loving plants may be planted on the inside edge, and sweet potato along the outside edge to provide a living mulch as well as extra production.

Strawberry Fields Eco Lodge, Ethiopia: Black Water Filtration System

Aid Projects, Biological Cleaning, Community Projects, Demonstration Sites, Education Centres, Land, Waste Systems & Recycling, Waste Water — by Alex McCausland October 26, 2010

Black water is the term applied to domestic waste water which carries solid organic waste materials and has a high level of nitrogen and phosphate containing compounds which may be in soluble and non soluble forms. Black water is generally assumed to refer to discharge from flush toilets, while grey water refers to outflow from showers, baths and hand basins, which contains no solid material and generally lower levels of nitrates and phosphates. Since all our toilets at Strawberry Fields are dry composting toilets our black water system does not have to deal with human waste at all. However, what we are dealing with is the waste water from the kitchen. Kitchen water can be considered as black water because dirty plates, frying pans and utensils carry a lot of fats, starches and protein. As well as this, the detergents which are necessary to remove all those from the surfaces of the utensils are stronger than body soap and carry a lot of phosphates which need some breaking down. The resulting mixture of soapy water, fat, protein and starch will quickly become very rancid if bacteria begin breeding in it, as it will go anaerobic and start producing swampy smelling gasses like nitrites which are poisonous to most plants (except for swamp plants which are adapted to deal with them).
