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.

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.
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.
‘Chasing Ice’ changed this climate-denying Bill O’Reilly listener into a believer Whenever you feel discouraged about working to fix global warming and convince people that it’s a real problem, watch this video: In the documentary Chasing Ice, filmmaker James Balog shot photos of glaciers in Iceland, Greenland, and Alaska at 30-minute intervals for months and months. As Grist has reported: The resulting time-lapse movie can condense months and years into a few mesmerizing moments. Now we can watch the canary in the coal mine as it expires.

History Left - a nutrient-poor oxisol; right - an oxisol transformed into fertile terra preta using biochar Oh, Snapchat: Your smartphone just became a climate scientist This is part of a series exploring how collective intelligence can create a better world. Read the whole series here. Picture this: You’re out on a hike in Mt. Diablo State Park, just outside San Francisco. Upon reaching a nice viewpoint, you think, “Hey, this would look pretty sweet on my Instagram feed.” Tree Disease identification, symptoms, treatment options for tree diseases There are many different diseases that affect landscape trees and shrubs. Control of tree and shrub diseases cannot be properly accomplished until the disease pest is identified. Identification of tree and shrub diseases is crucial because, although most diseases can be controlled, there are some diseases that cannot be controlled.
