But an equally alarming source of the decline, both Mr. Taylor and Mr. Vidal said, is the explosive increase in American farmland planted in soybean and corn genetically modified to tolerate herbicides. The American Midwest’s corn belt is a critical feeding ground for monarchs, which once found a ready source of milkweed growing between the rows of millions of acres of soybean and corn. But the ubiquitous use of herbicide-tolerant crops has enabled farmers to wipe out the milkweed, and with it much of the butterflies’ food supply.

No one is certain why Goss’s wilt has become so rampant in recent years. But many plant pathologists suspect that the biggest factor is the hybrids chosen for genetic modification by major seed companies like Monsanto, DuPont and Syngenta. “My theory is that there were a couple of hybrids planted that were selected because they had extremely high yield potentials,” said Dr. Robertson, whose research is financed by Monsanto and the Agriculture Department. “They also may have been highly susceptible to Goss’s wilt.”

About 90 percent of the corn grown in the United States comes from seeds that have been engineered in a laboratory, their DNA modified with genetic material not naturally found in corn species. Almost all American corn, for instance, is now engineered to resist the powerful herbicide glyphosate (often sold as Roundup), so farmers can kill weeds without killing their corn.

As farmers grow more corn to satisfy the demand for ethanol, they are rotating it less frequently with other crops.

German Study Finds GM Crops Good for Farmers and the Environment

making it the only variety in existence to produce beta carotene, the source of vitamin A. Its developers call it “Golden Rice.”

And they have motivated similar attacks on trials of other genetically modified crops in recent years: grapes designed to fight off a deadly virus in France, wheat designed to have a lower glycemic index in Australia, sugar beets in Oregon designed to tolerate a herbicide, to name a few.

Not owned by any company, Golden Rice is being developed by a nonprofit group called the International Rice Research Institute with the aim of providing a new source of vitamin A to people both in the Philippines, where most households get most of their calories from rice,

A Lonely Quest for Facts on Genetically Modified Crops

Nigeria’s real GDP is based on 1990 prices. It plans to update them to ones from 2008. Ghana did the same in 2010, revising its base year from 1996 to 2006. Its GDP shot up by 60%, propelling it overnight from being a poor to middle-income country, defined by the IMF as having a GDP per person of at least $1,026 a year.

What is ironic is that these vines represented about the least scary GMO crop imaginable.  They were engineered to be resistant to a disease called Fan Leaf Virus that is spread by nematodes that live in the soil.  Back before people understood this disease it was unintentionally spread to many grape-growing areas.  Once a given vineyard is contaminated with the nematodes and virus, grapes will only survive for a few years on that site before declining and dying.  Some of the best wine production areas around the world are seriously compromised this way, and there has been no lasting cure.

at was being tested in Colmar was a “rootstock.”  All grapes are cuttings of the desired variety (Gewurtztraminer, Cabernet, Chardonnay…) grafted on to a root that is resistant to various pests.  The Colmar roots would have also been resistant to the virus.  The top of the vine (all that is above ground) would be exactly like all the neighboring vineyards.  In theory the grapes wouldn’t die in a few years (that is what the researchers were hoping to demonstrate).

but this same irrationality is hindering efforts to provide things like virus resistant Cassava to poor farmers in Africa or virus resistant Papayas to people in Thailand. 

GUINEA: Winners and losers in Guinea’s bauxite industry

“Rather than making people richer, mining has made them poorer,” said Akoumba Diallo, a mining sector researcher. “It polluted their environments so they can’t grow crops or let animals feed near mining sites. And it is hard to get water anywhere because it’s contaminated.” With mining contributing to 85 percent of the country’s external revenue, and the World Bank estimating investments of up to US$20 billion in bauxite mining in Guinea over the next decade, the government is currently rewriting and renegotiating its mining contracts - unchanged for 25 years - with 15 companies to ensure Guineans are more likely to benefit from the wealth they spawn.

Mining companies are legally obliged to pay taxes to owners of the land they mine,

Seeds of domesticated squash found by scientists on the western slopes of the Andes in northern Peru are almost 10,000 years old, about twice the age of previously discovered cultivated crops in the region, new, more precise dating techniques have revealed.

The excavations also yielded peanut hulls and cotton fibers — about 8,500 and 6,000 years old, respectively

Their research also turned up traces of other domesticated plants, including a grain, manioc and unidentified fruits, and stone hoes, furrowed garden plots and small-scale irrigation canals from approximately the same period of time.
