Allan Savory: “Agriculture is More Destructive than Coal Mining”

Note that this post is part of a series of posts that I am making after attending the first ever Savory Institute International Conference held last week in my hometown of Boulder, Colorado.

The first talk to kick off the Savory Institute International Conference held in Boulder, Colorado last week was by the institute’s founder, Allan Savory.

Savory began his talk by explaining that he’s been addressing the subject of desertification for fifty years.

He rattled off soil erosion numbers. . . “our planet is losing 80-100 billion tons of soil per year,” calling that “the most frightening statistic in the world.”

He named some of the factors related to this soil loss, which included the burning of grasslands around the world, the loss of forests, the loss of biodiversity, and the silting of continental shelves.

Then, he explained to us that because healthy soils are an important natural reservoir of water, today we have a big problem of decreased effectiveness of rainfall due to degraded and eroded soil. This is caused by agricultural practices, not by climate change. Because healthy soils sequester Carbon, large soil losses and resting soils have led to a reduced capacity to mitigate climate change. So, agriculture is more destructive than coal mining or anything else going on in the world today. [1]

He questioned why people aren’t more aware of these facts, and then, proceeded to answer how we got ourselves into this situation.

He explained that the change began in the grasslands of the world when early humans developed plants and animals for food which altered or eliminated the grasslands. And, he explained that humans shelve their problems for future generations.

He went on by listing three problems that are causing an acceleration of these wrong agricultural practices: population growth; exploding technological advances; and a modern educational system which divides knowledge into parts so that we no longer see the whole.

Savory was on a roll here already, when next, he said he doesn’t understand why something that makes no sense, like turning 40% of the U.S. corn crop into ethanol is a policy, and there are so few people who protest it.

He questioned a system where not one dollar is spent saving soil but we spend billions looking for new oil reserves. “The world is leaderless,” he said.

He warned that, “Worse wars will be fought over water than oil.”

So, those are the problems, what is the Savory Institute doing to make solutions?

The Savory Institute is combining science, social, and environmental principles to reverse desertification at Savory Hubs which are popping up around the world. The goal is to remove the barriers to the human creativity and knowledge that we have, and then, teach and share this knowledge.

“The barriers to sensibility are 100 percent human caused,” he said. Working in Zimbabwe, Savory finds, is a good fit since “if any change occurs, it’ll happen in a small nation, not a large nation” further stating that such work would be impossible in the U.S.

Working with Zimbabwe leaders, he has seen the anger which arises from confusion of mixed messages from multiple sources that suggest different agricultural solutions. Who are these small nations to believe?

He likes the openness of agricultural policy in Zimbabwe, and then describes what it is like to pass agricultural legislation in the London Parliament, which he visited. There are so many complex pages to read, that the voters in Parliament give up trying to understand it, and just turn it back to those who wrote it to let them decide.

More quotes . . .

“We do not have a larger problem than our rising population and our deteriorating environment.”

Since the world is so very complex, “we need a holistic context.

“The role of the government in agriculture is to get out of the way for human creativity, and to remove the policy barriers.”

Bringing up another important world problem, he said that we have got to find benign sources of energy and develop them.

And yet another, “Because of desertification and other problems, many people are already migrating.”

“Nobody is talking about agriculture. Because of our agriculture, climate change will continue.”

“Although agriculture is the problem, it can also be the solution.”

He said that the world is crying out for leadership that will shift public opinion and that will come from ordinary people in communities. He added that most people are inherently good.

Then, he closed his talk with this question, “What can ordinary people do?”

Savory’s answer was a challenge to the audience with a call to action, “If you care about your children, put it on a war footing. Look in the mirror and ask yourself what did you do when you were in the prime of your life to help solve these problems?”

[1] This is to say that healthy soils would be capable of mitigating the CO2 that has been released from the burning of fossil fuels. This will be covered more fully in an upcoming post.

Grazing Enthusiast Allan Savory’s TED Talk

I’ve held this TED talk back to put up while I’m away from my desk for a few days, so if you haven’t seen it yet, watch this by Allan Savory. I understand it’s “gone viral”. I’ve featured Savory on this site a number of times before, including this interview by radio ecoshock.

For further reading, Aljazeera did a recent and fine piece about Australian farmers who are using integrated systems somewhat like Savory’s.

And, if you missed my recent and very popular piece about what some innovative North Dakota farmers are doing, it’s here.

Finally, here is a Canadian professor, Dr. Clark of Guelph University on the subject of rotational grazing.

TED Talk on Algae Biofuel Production by Jonathan Trent

The following 15 minute video is a talk by scientist Jonathan Trent, about his vision for biofuel production from algae in floating pods on the ocean. There are numerous versions of algae systems being studied today and so far none is close to economically viable, yet there is great hope for figuring out a way to make it viable at some point in the future. Trent works at NASA’s nanotechnology department, where he builds microscopic devices out of proteins from extremophiles — bacteria that live in the world’s harshest environments. His system is called OMEGA, or the Offshore Membrane Enclosure for Growing Algae.

MIT’s Kent Larson Shows Us a Glimpse of a More Efficient Tomorrow

At present, urbanization around the globe appears to be an unstoppable trend.

Architect Larson wants us to have the good things we like about cities and remove the bad things like too much space for cars and emissions. Using old-Paris as an example, neighborhoods are set up providing compact urban cell inhabitants of 20,000, or so, with everything they need in just a 5 or 10 minute walk.

He says that the city design of the 50s and 60s which is continuing to be built, is obsolete. The innovations that could make the city of the future more desirable will work a lot like a small village of the past.

He did not discuss food in particular, although he shows some urban farming on a top level space. Food stores would obviously be included in his compact urban cells.

In this video, Larson discusses:

  • “Robot” apartments with movable walls
  • Folding cars
  • Driverless cars communicating with pedestrians
  • Melbourne Laneways
  • Boulder’s bike paths and bike-share program
