How to Start a Small Permaculture Tree Nursery Recently I attended a farm forestry course with David Holmgren and Darren J. Doherty, a subject I’d like to address today. To even start a farm forestry operation, or even a permaculture orchard, you’ll need to source a huge number of trees from somewhere. I crunched a few numbers and browsed the relevant websites: it seems that small bare-root trees will cost, on average, $20 or more, an amount that will soon add up. I realised that, even excluding overseeding and site preparation, I would need to pay around $20k/acre for my permaculture orchard.

Allan Savory’s TED talk is wrong, and the benefits of holistic grazing have been debunked. Photo by Vyacheslav Oseledko/AFP/Getty Images When Allan Savory finished his TED talk early last month, foodies worldwide collectively salivated. In roughly 22 minutes, Savory, a biologist and former member of the Rhodesian Parliament, challenged the conventional wisdom blaming livestock for the degradation of global grasslands into hardpan deserts. It has long been a basic tenet of environmentalism that 10,000 years of overgrazing has caused this desertification. Environmentalists insist that to restore degraded landscapes, we must reduce the presence of cattle, eat less meat, and allow ecosystems to repair themselves. Nguiguis: Mango trees that grow without watering : Planting mango trees near piliostigma reticulatum shrubs (“nguiguis” in Ouolof) that will ensure water supply About the project Edit This is an incremental social innovation. It consists of first identifying a foot of piliostigma reticulatum, then probing the ground from the inside of the clump until there is a spot without roots. A hole the size of the tubes used in the nursery is dug at this spot.

Regrarian Handbook *1. CLIMATE CHAPTER’ eHANDBOOK (77 pages) available NOW for only AUD$5!! *ON SALE as a FULL HARDCOPY late-2015!! The ‘Regrarians Handbook’ is a succinct & sequential outline of over 300 integrated methodologies and techniques that have been proven over many years of universal application to work towards regenerating human & livestock’s lives along with production landscapes. It does so in a wholly practical, positive & pragmatic fashion, promising to be a relatively ageless tome that generations of users will refer to as they negotiate the design, development & management of systems they operate. Darren has joined forces with ‘Permaculture: A Designers’ Manual‘ (1988) Designer, Illustrator & Editor Andrew Jeeves in what promises to be the production of an ‘instant classic’.

Perennial Vegetables to Plant Once and Enjoy For Years To Come!!! Perennial vegetables—crops that you plant just once and harvest year after year—are relatively rare in North American gardens. With the exception of asparagus, rhubarb and artichokes, most gardeners are probably unaware of the tasty, extremely low-maintenance bounty that can be harvested when many annual crops aren’t available. A Brief History of Perennial Crops According to Perennial Vegetables by Eric Toensmeier, most North American gardening and farming traditions come from Europe, where there are very few perennial crops except fruits and nuts. Cold and temperate Eurasian agriculture centered around livestock, annual grains and legumes, and early European settlers to North America simply brought their seeds and their cultivation methods with them, including draft animals for plowing up the soil every year. However, in more temperate and tropical areas of the world, including much of North America, perennial root, starch and fruit crops were actively bred, selected and cultivated.

Sustainable Land Management - Our Expertise - Centre for International Cooperation, VU University Amsterdam Today a growing number of developing countries face food crises, climate change and demographic pressure. However land degradation is the biggest threat to the world’s rural poor. We support projects that strive to help people help themselves to look after their land better. Permaculture Courses One of Permaculture’s Holy Cows: the Death of the Swale - Permaculture Courses ‘The best place to store water is in the soil.’ When I first heard this saying, early on in my permaculture education, it was like a light bulb coming on. It just seemed so obviously true. After a couple of decades of practicing permaculture I realise that any blanket statement like that is almost certain to be wrong or at least only right in certain places and at certain times.

Biochar Biochar created through the pyrolysis process. History[edit] Left - a nutrient-poor oxisol; right - an oxisol transformed into fertile terra preta using biochar Copenhagen Consensus Center The following highlights have been determined using the recommendations provided in the assessment and perspective papers. Within the focus area of Biodiversity the target that has the best benefit-to-cost ratio (BCR) is: By 2030, stem the loss of coral reefs by 50% which will return more than $24 for every dollar spent. Other valuable targets within this focus area are: Reduce global forest loss by at least 50% which will return $10 for every dollar spent.Reduce global wetland loss by at least 50% which will return $10 for every dollar spent. The following target has an acceptable benefit-cost ratio, although some possible costs of reforestation carried out using exotic species may result in losses of biodiversity.
