Greywater Mulch Pits
Biological Cleaning, Compost, Conservation, Soil Conservation, Storm Water, Swales, Waste Water, Water Contaminaton, Water Harvesting — by Campbell Wilson
by Cam Wilson, Forest Edge Permaculture
Greywater mulch-pits provide an excellent solution when re-using greywater on your garden – they are cheap to construct, they improve the quality of water entering your soil and after some time provide you with valuable compost. They’re very easy to construct too. You basically just dig a hole, wack in some 100mm ag-pipe and then fill it up with nice chunky mulch.

‘Soil, Water & Carbon for Every Farm’ – Building Soils, Harvesting Rainwater, Storing Carbon
by Abe Collins & Darren Doherty
Introduction
Keyline Design was first developed by the great Australian, P.A. Yeomans (1904-1984), in the late 1940s & 50s initially as a practical response to the unpredictable rainfall regime he found on his new property, ‘Nevallan’, to the west of Sydney, New South Wales, Australia. Soil Conservation, as developed by the US Army Corp of Engineers was the predominant practice of the time and for a time Yeomans was influenced by this, though soon found some deficiencies with the pattern of water flow its application expressed. Yeomans went on to devote the rest of his life to the promotion, research and development of Keyline Design and in doing so was labelled by Permaculture co-originator Bill Mollison as "…one of Australia’s greatest patriots… ".
Influenced by the likes of prominent organic agriculture figures in Andre Voison, Friend Sykes, Newman Turner & Louis Bromfield (among many others!) Yeomans has been attributed with being the 1st person to accelerate soil formation through the stacking of methods, overturning the myth that it took 1,000 years to create an inch of topsoil. Yeomans proclaimed that "…the landman’s job is not so much to conserve soil as it is to develop soil, to improve his soil and to make it more fertile than it ever was…".

Report on our Iranian Consultancy Trip of December 2008
Aid Projects, Compost, Conservation, Courses/Workshops, Dams, Developments, Earth Banks, Gabions, Land, News, Plant Systems, Rehabilitation, Soil Conservation, Soil Erosion & Contamination, Swales, Trees, Water Harvesting — by Geoff Lawton
Editor’s Note: Iran has been making headlines in the media a great deal over the last few years. Here’s a side to the story you don’t normally get to hear, as experienced by our own Geoff Lawton.
We are applying Permaculture techniques to restore the landscape
in the hottest place on the planet
In December 2008 it was our great pleasure and honour to be invited to Iran to work for the Forest Rangeland Watershed Management Organisation, originally formed in 1928 (see Word doc on their work here). We were working with different departments of the organisation, like the Sand Dune Fixation Department that was formed in 1958 for the Bureau of Desert Affairs. All of this falls under the central government’s main organisation of Jihad Agriculture Ministry. We were invited to teach a 10-day Permaculture course focusing mainly on desert rehabilitation.

 Fig. 24.The heat island effect. An excessively wide, exposed, solar-oven-like residential street in Tucson, Arizona absorbs the sun’s heat during the day like a battery, then radiates it out at night. This local warming effect has raised summer temperatures in Tucson by 6°F (3°C) since the 1940s, which contributes to global warming since the higher temperatures result in people using air conditioners more, which are powered by electricity generated through the burning of coal. Note that no shade trees are planted in the public right-of-way along the street, leaving street and sidewalk baked. All runoff is drained off site leaving the development dehydrated.

My view of public streets was radically changed when I heard ecovillage designer Max Lindigger tell a story of an insightful walk he took with his grandfather. “Look there,” said his grandfather, pointing to condominiums being built on the once forested slopes above his village in the Swiss Alps. “That’s where we grew and gathered food during the war. The forests were common land, a reserve of community resources. What commons remain? Where will we grow and gather our food in the next catastrophe?”
I then looked at my Sonoran desert city of Tucson, Arizona and asked myself, “Where are my community’s forests, our commons? Where would we get our food in times of need?”

Phosphorus Matters
Compost, Food Shortages, Soil Composition, Soil Conservation, Soil Erosion & Contamination — by Marcin Gerwin
Part One: Closing the Phosphorus Cycle
|
|
It might sound ridiculous, but for every container of bananas, coffee, tea or cocoa imported, we should send back a shipment of a fluffy, earth-like smelling compost. Why is that? With each container of food we import nutrients taken up by plants from the soil. We import calcium, potassium, magnesium, boron, iron, zinc, molybdenum, copper and many others. One of the essential elements imported in food is phosphorus. For every ton of bananas we import 0.3 kg of phosphorus, for every ton of cocoa it’s 5 kg and for ton of coffee it’s 3.3 kg of phosphorus. Tea is a bit more complicated, because the amount of phosphorus depends on the origin of tea – for example in 1 ton of tea leaves harvested in Sri Lanka there are some 3.5 kg of phosphorus, while tea from South India contains 6.6 kg of phosphorus (1).

The Rise and Predictable Fall of Globalized Industrial Agriculture
Conservation, Consumerism, Economics, Food Shortages, Global Warming/Climate Change, Population, Soil Conservation, peak oil — by Craig Mackintosh
Today I’d like to introduce you to a (well written and beautifully presented) report, titled – ‘The Rise and Predictable Fall of Globalized Industrial Agriculture‘ (55 page, 2.4mb PDF). The title says it all. Should you be concerned? Yes.
Your concern, however, should not be that the globalised industrial agribusiness model will collapse – this is not only inevitable, but also necessary, and, might I add, desirable – the focus should instead be on when and how it will fall.
Let me explain.
If you were to ask the Average Joe what is the largest contributor to global warming, many will say cars, trucks and aeroplanes – or coal fired power plants. While these are large contributors, they cannot compete with the largest, yet mostly overlooked contribution from our present system of farming and global food trading. Global warming is primarily due to agriculture. Indeed, much of the above-stated contributors are merely essential aspects in maintaining the globalised agricultural model:

Humanure Handbook – Free Download
Compost, Conservation, DVDs/Books, Fungi, Potable Water, Rehabilitation, Soil Biology, Soil Conservation, Soil Erosion & Contamination, Waste Water, Water Contaminaton — by Craig Mackintosh
With chapters like ‘Crap Happens’, ‘Deep Shit’ and ‘A Day in the Life of a Turd’, this is sure to be an interesting book, albeit possibly not one to read over lunch?
With this wonderful substance piling up in all the wrong places (after all, we’re running out of clean water, and yet we’re crapping in it…), this taboo topic deserves a lot more attention than it gets. Enjoy the book – and special thanks to the author Joseph Jenkins for making this freely available (warning: 22mb PDF – if you want to download chapter by chapter, scroll down on this page, or just read online here).

Soil – Our Financial Institution
Biological Cleaning, Conservation, Rehabilitation, Soil Biology, Soil Composition, Soil Conservation, Soil Erosion & Contamination, Structure — by Craig Mackintosh
by Craig Mackintosh – originally published on Celsias
Soil – the substance you walk on, build on, and live from – provides your food, clothing, and even the air you breathe. It gives warmth, shelter, and the goods you possess. Soil is, I believe, a substance that is under-acknowledged, and also under attack, and its misuse is contributing greatly to the excessive release of CO2 into our atmosphere – making it a large contributor to global warming. Therefore, I felt it high time we came to its defense. Here goes.

Small is Bountiful
Food Shortages, Population, Soil Conservation, Soil Erosion & Contamination — by George Monbiot
by George Monbiot – journalist, author, academic and environmental and political activist. Originally published in the Guardian, 10 June 2008
I suggest you sit down before you read this. Robert Mugabe is right. At last week’s global food summit he was the only leader to speak of “the importance … of land in agricultural production and food security”.(1) Countries should follow Zimbabwe’s lead, he said, in democratising ownership.
Of course the old bastard has done just the opposite. He has evicted his opponents and given land to his supporters. He has failed to support the new settlements with credit or expertise, with the result that farming in Zimbabwe has collapsed. The country was in desperate need of land reform when Mugabe became president. It remains in desperate need of land reform today.
