Trees are one of our most powerful tools to pull carbon from the atmosphere and sequester it in the soil for long-term storage. This is why reforestation and protecting intact forests are such important parts of plans to address climate change. Conventional climate change science tells us that the planet’s capacity for reforestation is limited, however, by the need to preserve land for agriculture.
But movements like agroforestry and permaculture show us that farming and trees are not mutually exclusive. From tree crops to contour strips of nitrogen fixing trees between bands of annual crops, there is a wealth of techniques that can give us the best of both worlds. These techniques, should a global effort get behind their implementation on a large scale, could have a major impact on climate change. They would also have numerous other benefits to the planet and its people.
A century ago, writer-farmers like J. Russell Smith coined the term “permanent agriculture” to describe food forestry and other farming practices that combated a key issue of their day — erosion and degradation of farmland. From Smith and his compatriots we in permaculture have taken the name of our movement, though our movement has grown to encompass much more than food forestry. Today these visionary ideas are more essential than ever, to address an environmental crisis on a scale Smith and his contemporaries could not have imagined.

As people become urbanised, they start looking at the world in urban ways. What does that car or house say about that person? How does that person’s occupation affect their social standing? People may not admit it, but they understand the answers to these questions intuitively. As permaculturalists, we need to apply these same observational skills to our permacultural adventures.
These observational skills are important for permaculture because they allow you to read a landscape. No two pieces of land are ever the same! Whether that land is in an urban area or a rural area you can gather a huge amount of information as to its suitability for your next permaculture project simply by observation over a period of time. These skills will also allow you to identify ways to adapt your land to your particular purpose.
Reading a landscape is an observational skill so I have decided to take you on a virtual tour of the mountain range that I live in and tell you what I see in the different spots that we stop off at. I will highlight things at each location that I have learned on my food forest permaculture journey, and that I hope to impart to you the reader. I hope you enjoy the tour!

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.
Comments (6)The Plow That Broke the Plains
Biodiversity, Food Shortages, Regional Water Cycle, Society, Soil Erosion & Contamination — by Craig Mackintosh PRI Editor December 5, 2011
I love history. As they say, if you don’t learn from it, you’re destined to repeat it. The video below, circa 1937, is a fascinating look at how men forsook the crucial observational stage when making the best laid plans of mice and men and in doing so took an enormous swathe of stable prairie, steppe and grassland environments and literally turned them into dust.
As the narrative comments:
Settler, plow at your peril!

The Dehydration and Rehydration of the Australian Landscape
Conservation, Gabions, Irrigation, Land, Regional Water Cycle, Rehabilitation, Soil Conservation, Soil Erosion & Contamination, Storm Water, Water Contaminaton & Loss, Water Harvesting — by Campbell Wilson November 23, 2011
Article and diagrams copyright © Cam Wilson
This is a pictorial tour of the degradation and dehydration process that the Australian landscape went through post European settlement, along with one of the major aims of Peter Andrews’ Natural Sequence Farming approach, namely the rehydration of the Australian landscape.
If you were one of the early explorers, walking into a wide floodplain system in the early 1800s, more than likely you would have found some form of discontinuous watercourse. One example is known as a ‘chain of ponds’, in which you’d find small bodies of open water, about a metre below the level of the floodplain, held in place and separated from the next pond by a marshy plug of reeds such as Phragmites.

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.

Introduction
Why did the photojournalist cross the road? It sounds like the beginning of a joke, and, in a way, it was. I was standing at a busy road in Amman, Jordan, contemplating crossing. I say ‘contemplating’ as there were three lanes in each direction, and the traffic was moving fast. Several hundred metres away I spied a pedestrian overpass, but, before reason could sway impulse, I saw an opening and took it. Then, with three lanes behind me, standing proudly on the 1-metre wide centre strip, it seemed that the deity in charge of roads decided to conspire against me…. In the 37°C+ heat, I watched, waited, and then watched and waited some more. The minutes dragged by. A few times I ventured one foot forward, only to snatch it back again. The sun blazed. I began to have visions of being stuck here until the traffic slowed in the evening….
Comments (16)Owen Hablutzel: “Water and Transformation in Dryland Systems – Resilience Science & Keyline Application” (IPC10 Presentation – Video)

Owen’s talk here is quite fascinating. While most in permaculture will recognise the importance of mainframe design, Owen’s talk goes a step further, and dips headlong into mainframe concepts as well. If you’re one of those right-side brain type people who just loves thinking a little above and beyond and immersing yourself into a bit of creative theory, you’ll find this talk from Owen hard to pause. If it doesn’t sound like your cup of tea, don’t panic, as Owen brings the theoretical aspects back onto the ground throughout, to show how it plays out (and boy does it play out) on a tangible property he’s been working on in the U.S. of A. — in this case the large broad acre Whirlwind Farm. In essence, Owen’s talk is about restorative, resilience farming: how we can think about it, and achieve it.
Comments (4)Poll Indicates Lack of Confidence in Murray-Darling Basin Authority Plans

Initial results of an ongoing on-line poll on water policy in Australia raise concerns that the majority of Australians are far from convinced that the draft Basin Plan, soon to be released by the Murray-Darling Basin Authority, will be successful in its aims.

Tony Rinaudo’s IPC10 conference presentation was one of the highlights of the event for three good reasons — 1) because of the scale of impact his Farmer Managed Natural Regeneration (FMNR) work has achieved (more than 30,000 km² of re-greened, regenerated land to date); 2) the utter simplicity — and thus doability — of this work (it requires no financial investment or out-of-reach technologies, only a little educational guidance and community collaboration), and 3) the speed at which this regeneration can occur and lives can improve.
We’ve brought people’s attention to FMNR before…

Looking for a transitional form of agriculture as we try to wean ourselves off fossil-fuel based farming systems into smaller scaled, localised and sustainable ways of providing for ourselves? Enter, alleycropping — the practice of planting rows of trees (ideally on contour) through fields to create alleys, or corridors, of alternating trees and ground crops.
Comments (3)Growing Water Deficit Threatening Grain Harvests
Conservation, Food Shortages, Irrigation, Regional Water Cycle, Water Contaminaton & Loss — by Earth Policy Institute July 22, 2011
by Lester R. Brown, Earth Policy Institute
Many countries are facing dangerous water shortages. As world demand for food has soared, millions of farmers have drilled too many irrigation wells in efforts to expand their harvests. As a result, water tables are falling and wells are going dry in some 20 countries containing half the world’s people. The overpumping of aquifers for irrigation temporarily inflates food production, creating a food production bubble that bursts when the aquifer is depleted.
The shrinkage of irrigation water supplies in the big three grain-producing countries—the United States, India, and China—is of particular concern. Thus far, these countries have managed to avoid falling harvests at the national level, but continued overexploitation of aquifers could soon catch up with them.
