School children take part in Nendo Dango in Argentina´s Rio Negro Province, Patagonia.
As part of a reforestation program around Argentina´s Eco Capital, El Bolsón, 21 schools have transformed their assembly halls into assembly lines for the production of over 25,000 seed clay balls utilizing the ancient technique of Nendo Dango. The method, re-invented by the ´father of natural farming´, Masanobu Fukuoka, was taught to the people of El Bolsón 3 years ago when Panos Manikis, Fukuoka´s most learned disciple, came to hold a series of workshops. Today, led by an inspiring group of permaculture activists, the technique is being used to do more than just rejuvenate the 1,200 hectares of forest that was incinerated in a 3-day fire earlier this year.Comments (3)

People do not normally leave their homes, their families, and their communities unless they have no other option. Yet as environmental stresses mount, we can expect to see a growing number of environmental refugees. Rising seas and increasingly devastating storms grab headlines, but expanding deserts, falling water tables, and toxic waste and radiation are also forcing people from their homes.
Advancing deserts are now on the move almost everywhere. The Sahara desert, for example, is expanding in every direction. As it advances northward, it is squeezing the populations of Morocco, Tunisia, and Algeria against the Mediterranean coast. The Sahelian region of Africa—the vast swath of savannah that separates the southern Sahara desert from the tropical rainforests of central Africa—is shrinking as the desert moves southward. As the desert invades Nigeria, Africa’s most populous country, from the north, farmers and herders are forced southward, squeezed into a shrinking area of productive land. A 2006 U.N. conference on desertification in Tunisia projected that by 2020 up to 60 million people could migrate from sub-Saharan Africa to North Africa and Europe.Comments (4)

Maddy Harland meets Polly Higgins, a barrister who is campaigning for the United Nations to adopt an additional crime against peace: Ecocide.
by Maddy Harland, editor of Permaculture magazine – inspiration for sustainable living
In my two decades working for Permaculture magazine I have met many fascinating and wonderful human beings but my recent meeting with the barrister and campaigner, Polly Higgins, was a turning point. She prompted a leap in my understanding of the power of law and our collective capacity to change the world overnight. I had heard of Polly’s campaigning work but I had not fully realised the far-reaching potential of international law. Polly deftly stretched my worldview. Bear with me if the subject of ecocide sounds grim… the outcome of these meetings was utterly inspirational.
What is Ecocide?
There are already four international Crimes Against Peace: Genocide, Crimes Against Humanity, War Crimes, and Crimes of Aggression. Polly says there is a missing 5th Crime Against Peace and that crime is Ecocide: the destruction of large areas of the environment and ecosystems. Obviously ecocide can be caused by severe weather events like tsunamis and volcanic eruptions, not directly attributable to specific human activity but there is another category: Ascertainable Ecocide. This is the destruction, damage or loss to the territory, caused by human activity – people, corporations, and nations. Activities such as nuclear testing, the exploitation of resources, mining practices like tar sands extraction, the dumping of harmful chemicals or the use of defoliants, the emission of pollutants or war. Examples of ascertainable ecocide affecting sizeable territories include:Comments (13)

A comprehensive, lasting security is created through giving people a viable means to provide for themselves.
The ultimate goal should be to enable the country of Somalia and its people to create a self-sustaining economy of their own. Only then will there be a meaningful, lasting peace.Comments (1)

The thin layer of topsoil that covers much of the earth’s land surface is the foundation of civilization. As long as soil erosion on cropland does not exceed new soil formation, all is well. But once it does, it leads to falling soil fertility and eventually to land abandonment. As countries lose their topsoil through overgrazing, overplowing, or deforestation, they eventually lose the capacity to feed themselves. Among those facing this problem are Lesotho, Haiti, Mongolia, and North Korea.Comments (1)

Many of you will remember the inspiring and encouraging example of earth restoration found in the story of the Loess Plateau in China (see links at bottom). John Liu was the man heavily involved in this amazing and very large scale initiative. In this new video, below, you’ll see Mr. Liu turning his eyes toward Africa, where Rwanda is now the focus of an earnest bid to restore its degraded forests and farmland, whilst simultaneously improving the lives of the communities they host. You’ll see many excellent examples of holistic thinking in this short documentary.
You’ll also learn of the praiseworthy work of Dr. Rene Haller, whose observational skills are highly adept at tailoring biological solutions towards rehabilitating the most degraded of lands.

I’d like to revisit a few points I brought up in a piece that appeared here at the PRI Australia website in April last year; “Things That Can’t Last Forever, and Things That Can: A Few Thoughts”.
I’d like to begin with the following premise:
Economics is a continuation of energy by different means.
Classical physics defines energy as the ability to do work. Money represents the ability to do work. Fossil fuels furnish the ability to do work — quite a great deal of it — and, for the moment, relatively cheaply when one accounts for the finite nature of its supply in relation to what it facilitates.Comments (6)

During the years when governments and the media were focused on preparations for the 2009 Copenhagen climate negotiations, a powerful climate movement was emerging in the United States: the movement opposing the construction of new coal-fired power plants.
Environmental groups, both national and local, are opposing coal plants because they are the primary driver of climate change. Emissions from coal plants are also responsible for 13,200 U.S. deaths annually — a number that dwarfs the U.S. lives lost in Iraq and Afghanistan combined.Comments (4)

This video is from way back in 2004, so some of the political comments at the end are way out of date, but, that trivia aside, the rest of the video is one of the best presentations of holistic common sense I’ve heard in quite a while. I think many of you will find a lot of satisfaction in listening to David’s lucid observations on how natural systems work.Comments (2)

They say if we don’t study history, we’re destined to repeat it. Many of you will be familiar with Jared Diamond and his work. Author of Collapse: How Societies Choose to Fail or Succeed, Mr. Diamond has put a lot of energy into studying various cultures that have come, and, significantly, gone again. Amongst these is the example of Easter Island, where it appears that despite the islanders’ major resources being clearly in decline, they continued to use these resources for their own particular, peculiar economy — that being to make their giant Moai idols. Not only that, but, over time, as the resources needed to create them dwindled, the Moai statues only got larger. Their economy not only had to continue, but it had to grow — regardless of their context, and despite what should have been obvious consequences.
Some dispute the exact nature of the collapse of Easter Island, but what we do know is that pollen samples taken from the island show that it was once covered in forest, yet by the time Europeans arrived the island was treeless. There are no pollen traces dated beyond around 1650, around the same time the statues ceased being made. Surviving clans after this time, no longer able to create more competing statues, instead took to pushing over those of rival clans — until by 1868 all the Moai had been toppled, and many beheaded.Comments (12)

Yesterday we were talking about the great need to transition our agriculture (and our culture for that matter) to be based in systems (or integrated) thinking, rather than the segregated, reductionist monoculture mind set we have today. There’s perhaps no better example of systems-based thinking in practice than a well developed biodiverse ‘forest garden’ (or what is called a food forest in many places). Along with our own Geoff Lawton, Martin Crawford of the UK’s Agroforestry Research Trust is one of the world’s best recognised practitioners of the art. The following video gives us a peek at his work.

In Melbourne, on April 5th and 6th, was held the National Sustainable Food Summit, where key Australian food and agriculture players and academics met to discuss the challenges and possible solutions for Australia’s increasingly vulnerable food security situation. Some of the talks were quite interesting.
The first video is where Julian Cribb (Adjunct Professor of Science Communication at the University of Technology Sydney and a Fellow of the Australian Academy of Technological Sciences and Engineering (ATSE)) boils some of the main issues facing us down into a short, understandable presentation. He gives a good overview of the problems — like that we’re in dire need of increasing food production right at a time where, due to our past and present activities, we’re seeing clear evidence that we’ll have to do so with less energy, less land, less water, less phosphorus and all whilst enduring an ever-more-erratic climate response. I’m not in full agreement with all of his solutions though — for example I’m not keen to start eating algae biomass grown in a tank…. But, I think that given the nature of the issues we are and will have to grapple with, I don’t blame him for coming to such conclusions. Indeed, if we don’t start implementing real, lasting solutions soon, then eating algae goop may become more attractive to me in the future than it does today…. (hence my personal sense of self-preservation leads me to expend my energies trying to promote permaculture!)
Julian Cribb: What are the future challenges to our food system?

The Malungon area of the Sarangani province, located in the southern region of The Philippines, was once one of the richest forests in the world. Today the remaining old growth exists in small, fragmented stands which remain vulnerable to illegal deforestation and degradation. Frequently ignored, these last remaining areas are a vital core habitat for a wide range of fauna and flora. This forest has also been, for at least 2000 years, the centerpiece of the culture and lifestyle of the Blaan and Tagakaulo indigenous peoples.Comments (4)
