An excellent interview of Allan Savory by Jonathan Teller-Elsberg deals with the difference between reductionist research and process-oriented management, and brittle and nonbrittle environments. Posted here.

Attached below is a simple draft greenhouse gas calculator for grass and cattle producers, in Microsoft Excel format. This calculator differs from many in that it recognizes that soil, and soil biology, is a principal factor influencing the composition of the atmosphere. To judge or quantify such effects, site-specific measurements are needed, such as changes in soil carbon levels over time.

The promise of a calculator is that you can assess your consumption of resources, or your impact, and presumably be motivated to reduce it. However, the world is not just an input-output system, or collection of sinks and sources. There are complex interdependencies, flows, and cycles. When people say that it takes a village to raise a child, they do not mean that a village is destroyed for every child raised. There can be synergy, mutual benefit. Likewise for the water, solar energy, and carbon that goes into life processes. They are not destroyed.

However, there seems to be popular demand, and this draft calculator is a response to that demand, and an effort to enlarge perceptions of the interdependencies.

For most grass-based cattle producers, the major fluxes of greenhouse gases are likely to be methane from enteric fermentation, and changes in soil carbon levels.

The calculator comes preloaded with fictitious figures based on a 10,000 acre property, with 600 cow-calf pairs, that ships 800-pound yearlings.

Suggestions welcome.

Filmmaker John Liu has documented the World Bank's $500 million loess plateau watershed rehabilitation project since it began in 1995. He has made at least two compelling films about the project, including a 22-minute version was shown at the recent Copenhagen climate conference, and a more detailed 52-minute version.

Thanks to Tony for the tip.

The UK Soil Association has a wide-ranging and thorough report on the potential of agriculture to increase soil carbon. Highly recommended as a broad overview of the soil carbon opportunity

We are embarking on a mapping project for measured changes in soil carbon content over time. The purpose is not to aggregate "offsets" or to make broad predictions, but to show what's possible as verified by actual measurements.

There are many stories that are told about soil carbon, and what its possibilities are. Much conversation on this topic has substituted assumptions for observations. Repeated measurements at the same location appear to be rare.

There are only a few data points so far and we hope to collect, review, and add data as we can. If you have data you would like to include, or can suggest good data, please contact us, info at soilcarboncoalition dot org, or you may start with a data form attached below.

Carbon gains and losses are expressed in metric tons of carbon (not carbon dioxide) per hectare per year, or as annual percentage increase where bulk density measurements have not been taken.

You may use the Google Earth version if you have Google Earth installed.

Otherwise use the Google Maps version.

You may view the data points in page format here, and even subscribe to an RSS feed.

To convert carbon to CO2, multiply by 3.67. For CO2 to C, multiply by .273. (The molecular weight of CO2 is 16 for each oxygen atom, and 12 for the carbon atom, so the ratio of CO2 to C is 44:12.)

To convert hectares to acres, multiply by 2.47. To convert acres to hectares, multiply by .404.

To convert metric tons C per hectare to metric tons CO2 per acre, multiply by 1.52. To convert tons CO2 per acre to tons C per hectare, multiply by .658.

It is often said that you can't unscramble an egg. An egg has a wholeness or integrity, a poised arrangement of membranes and layers. You cannot reverse the breaking, mixing, and cooking, even with the most advanced technology and equipment.

But a hen can. Feed her a scrambled egg or two, and she can lay a new, whole egg. It may not be instant, but expensive technology is not required. If the egg is fertile, it can become a new hen, who can unscramble more eggs, and so on.

It's important to remember the relationship here, and who has the power. The hen wants to eat it, and produce a new egg, for reasons that are hers, not ours. Like all the biosphere's organisms, she is self-motivated. Trying to force her may cause problems for both her and us. If we want the egg unscrambled, we invite her.

We've got a scrambled egg situation on a global scale: biodiversity loss, extensive land degradation, water shortages, acidifying oceans, and too much heat-trapping carbon in the atmosphere. But we've framed it in such a way that the hen isn't even in the picture.

Of all these large problems, it was perhaps inevitable that carbon in the atmosphere took center stage in the 1970s and after. The data about rising carbon dioxide in the atmosphere were clear. Physical sciences were dominant in climate questions, and the scope and variability of the biological carbon cycle were only beginning to emerge.

That transparent carbon dioxide gas absorbed and emitted long-wave radiation, thus trapping heat, had been discovered in the 1800s. By the 1960s it was clear that atmospheric carbon dioxide was increasing steadily. But it took another generation, as well as a massive and varied accumulation of evidence, before most scientists and the public began to accept the possibility that climate could change as a result of human activities, and that fossil fuel burning was the main driver.
