Corn most profitable: not GM

Steve Connor writes in the Independent that It pays not to cultivate GM crops, survey finds,
The first economic analysis of growing genetically modified crops on a wide scale has found that the biggest winners were the farmers who decided not to grow them.

The study, which looked at maize yields in the corn belt of the United States, found that farmers who continued to grow conventional crops actually earned more money over a 14-year period than those who cultivated GM varieties.

The article then tries to say they nonetheless benefited from genetic modification:
All farmers benefited from the significantly lower level of pests that came about after the introduction of GM maize to the US in 1996, but the conventional farmers who continued to cultivate non-GM varieties also benefited financially from not having to pay the extra costs of purchasing GM seeds.
Um, what about not having to pay for the pesticides that go with the GM seeds? The study’s author admits they didn’t study that sort of thing:
“Additionally, environmental benefits from corn borer suppression are likely occurring, such as less insecticide use, but these benefits have yet to be documented,” Dr Hutchinson said.
The Telegraph spelled his name wrong. This appears to be the actual report:
Areawide Suppression of European Corn Borer with Bt Maize Reaps Savings to Non-Bt Maize Growers

The full text is behind a paywall, but the abstract concludes with:
…and highlight economic incentives for growers to maintain non-Bt maize refugia for sustainable insect resistance management.
So growing 98% of crops from GM seeds, as is the case in Georgia, is a bad idea.

EMC Spraying Poison Beside a Public Highway

Ever wonder why all the trees and shrubs die under the power lines? Company workers spray toxic chemicals on them. Driving on GA 122 between Pavo and Barney and saw some electric company spraying going on. This fellow didn’t seem happy I was recording:

Note that this worker is unprotected from this poison. No eye covering, no mask. Spraying is a shame in many ways.

Why do they do this? Continue reading →

Fixing a perfect storm of bad planning and design

Asked about typical modern shopping corridors, Texas A&M Assistant Professor of Landscape Architecture and Urban Planning Eric Dumbaugh replied:
“from a traffic safety perspective, the modern commercial arterial is a perfect storm of bad planning and design. These roads are designed to support high operating speeds, making it difficult for drivers to stop quickly to avoid a crash, and the presence of commercial and retail uses on these roads means that drivers will routinely need to stop quickly in order to avoid crashing into pedestrians, bicyclists, and especially vehicles turning in and out of driveways.”
The 2006 article, Safe Urban Form: Revisiting the Relationship Between Community Design and Traffic Safety, by Eric Dumbaugh and Robert Rae, notes: Continue reading →

Trees make streets safer

Beta New Urban Network reported 1 September 2006 that Research: trees make streets safer, not deadlier:
Proposals for planting rows of trees along the roads — a traditional technique for shaping pleasing public spaces — are often opposed by transportation engineers, who contend that a wide travel corridor, free of obstacles, is needed to protect the lives of errant motorists.

Increasingly, however, the engineers’ beliefs about safety are being subjected to empirical study and are being found incorrect. Eric Dumbaugh, an assistant professor of transportation at Texas A&M, threw down the gauntlet with a long, carefully argued article, ”Safe Streets, Livable Streets,” in the Summer 2005 issue of the Journal of the American Planning Association. A follow-up article by Dumbaugh, in the 2006 edition of Transportation Research Record, will present further evidence that safe urban roadsides are not what the traffic-engineering establishment thinks they are.

Though engineers generally assert that wide clear areas safeguard motorists who run off the roads, Dumbaugh looked at accident records and found that, on the contrary, wide-open corridors encourage motorists to speed, bringing on more crashes. By contrast, tree-lined roadways cause motorists to slow down and drive more carefully, Dumbaugh says.

Dumbaugh examined crash statistics and found that tree-lined streets experience fewer accidents than do “forgiving roadsides” — those that have been kept free of large, inflexible objects. He points to “a growing body of evidence suggesting that the inclusion of trees and other streetscape features in the roadside environment may actually reduce crashes and injuries on urban roadways.”

The study asks a key question: Continue reading →
