Will peak oil force the localization of agriculture?

Stuart Staniford says no. Sharon Astyk says yes. Jeff Vail also says yes.

Let cows eat vaccines along with distillers grains

In December, a study came out suggesting a link between distillers grains — a waste product of the corn-ethanol process — and a spike in cases of beef tainted with the deadly E. coli 0157 virus. You see, the government-mandated ethanol boom has dramatically pushed up corn prices. To cut costs, feedlot operators have been […]

Notes on California’s big sustainable-farming conference

Note: This is another in a series of posts from Eco-Farm, the annual conference held by the Ecological Farming Association of California. At Eco-Farm, some 1,400-1,500 organic farmers, Big Organic marketers, and sundry sustainable-ag enthusiasts pack into a rustic, beautiful seaside conference hall an hour-and-a-half south of San Francisco to talk farming amid the dunes. […]

A long-time beekeeper’s take on colony collapse

Is it possible for an NFL star to go meatless?

Grist recently published my interview with Rory Freedman, one of the authors of vegan diet book Skinny Bitch. The finished piece is just a selection of the topics from our conversation (we had quite a long lunch), and one of the questions that didn’t make the cut was about responding to critics who say veganism […]

Orange County opens recycled-water plant

A sewage reclamation plant officially opened today in Orange County, Calif., and will, sure enough, reclaim treated effluent and turn it into drinking water. Recognizing that its growing population — currently 2.3 million — is likely to outpace its supply of fresh water, O.C. is relying on the facility to turn 70 million gallons of […]

The most critical assumption on cellulosic biofuels: yields

My most critical assumption with cellulosic biofuels is on land efficiency: tons of biomass per acre, and hence gallons of fuel produced per acre, and more accurately, miles driven per acre. I believe biomass yields per acre will multiply by two to four times from today's norms.

The lack of genetic optimization and research on cultural practices, harvesting, storage, and transport with would-be energy crops -- miscanthus, sorghum, switchgrass, and others -- means that there is significant potential for improvement. The application of advanced breeding methods like genetic engineering and marker-assisted breeding, limiting water usage through drought resistant crops, and large-scale application of biotechnology (i.e., optimizing the process by which plants conduct photosynthesis, or reducing stress-based yield losses) will also contribute to increased yields with fewer inputs.

More importantly, different energy crops are likely to be optimal for different climates -- jatropha makes sense on degraded Indian land, but not in the American Midwest. Rather than a single dominant energy crop, we are likely to see a variety of feedstocks that allow specialization to local conditions, mixes, and needs, while mitigating the risks.

The mercury problem isn’t contained to New York City’s sushi restaurants and markets

In case you needed another reason not to consume the dangerously overfished bluefin tuna: This week, The New York Times had a story about a study of mercury contamination, conducted by the newspaper, of leading sushi restaurants in New York. Guess which species showed the highest level of mercury? In the study, the Times collected samples of tuna sushi from leading restaurants like Blue Ribbon Sushi and Nobu Next Door. The results "found so much mercury in tuna sushi from 20 Manhattan stores and restaurants that at most of them, a regular diet of six pieces a week would exceed the levels considered acceptable by the Environmental Protection Agency."

In addition, the Times noted that "sushi from 5 of the 20 places had mercury levels so high that the Food and Drug Administration could take legal action to remove the fish from the market." In a sidebar about the health risks related to mercury, the Times noted that "several studies have concluded that elevated mercury levels may be associated not only with neurological problems but with cardiovascular disease among adults as well."
