Missing the story on Golden Rice, by Ben Billiston of IATP

A gaping hole in U.S. coverage is the perspectives of Philippine farm organizations, like the Asian Farmers Association affiliate PAKISAMA, or really anyone from the Philippines who opposes Golden Rice. By not including these voices, these reports miss a fundamental issue at the center of all issues around genetically engineered (GE) foods: power. Who controls the technology? Who controls what farmers can grow, and what people eat? Not coincidently, these questions are also at the center of addressing global hunger.

Opposition to Golden Rice needs to be placed in the global context of how the biotech industry has relentlessly and aggressively (with the assistance of the U.S. government) thrust this technology on the rest of the world. Resistance to GE crops is widespread around the world among both developed and developing countries, often led by farmers and aligned organizations. SEARICE (the Southeast Asia Regional Initiatives for Community Empowerment) offers insight by describing the experience of Philippine farmers after the introduction of GE Bt corn: corn farmers lost access to traditional varieties, they can no longer share or exchange seeds with other farmers, and they are paying double the cost for GE seeds for what is largely the same yield, leading to increasing indebtedness.

A meeting of the Council for Biotechnology Information (BIO) in Europe in March 2013.
Earlier this week, Andrew Pollack reported in the New York Times that biotech companies like Monsanto, Dupont and Dow Chemical announced through an industry association that they would be more transparent with the public about the chemicals and genetically modified seeds they sell. According to Cathleen Enright, executive vice president at the Council for Biotechnology Information (BIO), “We have not done a very good job communicating about GMOs. We want to get into the conversation.”
To move that conversation along, they’ve opened a new web site, GMOAnswers.com. Any move toward greater transparency from companies who have spent decades suing farmers, spending millions to prevent the labeling of food containing GMOs, hiring private security firms to break into their critics offices and steal information—not to mention generally bullying anybody who questions the safety and value of their products—should be good news. But like with most news from chemical and seed companies, it is another reason to worry that the public will be misled and the issues will be futher obfuscated.

The resistance to resistance: What is a weed?

By Dennis Keeney

The ability of natural systems to overcome assaults by outside forces that threaten their livelihood is nothing short of phenomenal. When I was kid growing up in Iowa in the 1950s, I recall when we sprayed DDT on the cows to control flies, except the flies soon fought back, so we had to use more. First used as an outgrowth of nerve gas from WWII, DDT was regarded as a lifesaver for control of mosquitoes carrying malaria but it soon became ineffective. Never mind that the full health and environmental risks of toxic DDT were never fully evaluated before it was in widespread use, and when it was found in milk, some people began to worry. Other pesticides, such as dieldrin and aldrin, were substituted, but mosquitoes again became resistant in 18 months or less.

Not to be deterred, humanity has continued to try to use pesticides to control pests over and over—only to find that pests continue to fight back over and over. Now more than 500 species of insects and fungus are resistant to pesticides and the list continues to climb.

Even corn rootworm, which used to be controlled by alternating corn with another crop such as soybeans, has figured out that it can exist nicely with the soybean and come back the next year, a phenomenon known as extended diapauses.

Aside from insects, resistance also operates efficiently in the plant world. Weeds are ever with us. Indeed they are called weeds because they end up where they are not wanted and cause economic damage. In 1943 Aldo Leopold wrote a classic essay called “What is a Weed.” The essay, published in River of the Mother of God (UW Press), said “To live in harmony with plants is, or should be, the ideal of good agriculture. To call every plant a weed which cannot be fed to livestock or people is, I fear, the actual practice of agricultural colleges. [...] The first false premise is that every wild species occasionally harmful to agriculture is by that reason of fact to be blacklisted for general persecution.”

I spent many hot days chopping weeds out of corn and soybean fields when I was a youth. When a miracle product called 2,4-D (an early Monsanto product) came along to use on the corn fields, I rejoiced. But lo and behold, by 1957, weeds were reported in Hawaii sugarcane fields that were resistant to 2,4-D. Weed scientists did not worry much. The slow growth pattern of weeds meant it would take many years before widespread resistance would occur. But weeds did not wait.

The triazines, especially atrazine, came into widespread use the 1960s. Predictably, weed resistance soon developed. While triazine resistance is commonplace, atrazine remains a major herbicide for corn.

But all was not lost. In the 1970s a Monsanto organic chemist named John Franz found a triamine salt, called glyphosate, that had broad spectrum toxicity toward green plants. Glyphosate was branded as Roundup and formulations were first marketed in 1976. Over the last three decades, glyphosate has brought enormous profits to Monsanto, which had exclusive U.S. rights until 2000 when the patent expired. Roundup has been the most widely sold herbicide worldwide since 1980.

The company’s profits greatly expanded with the introduction of crops genetically engineered to be tolerant of Roundup. With the introduction of Roundup Ready (RR) crops patented by Monsanto, the company's sales not only of the chemical but also of the seed and associated patents skyrocketed.

Over 90 percent of soy, 75 percent of cotton and 70 percent of corn grown in the U.S. in 2009 contains the RR trait. This amounts to 130 million acres of corn and soy, according to the U.S. Department of Agriculture.

While Roundup has been touted as safe and environmentally friendly, much data indicates the contrary. Of particular concern are the “inert” adjuvants (chemicals added to enhance the activity of the pesticide) that often are not disclosed nor tested by EPA.

From IATP- What we don't know about GE crops

—Ben Lilliston

After 15 years on the market, and constituting 80 percent of soybeans, corn and cotton grown in the U.S., we still know remarkably little about genetically engineered (GE) crops; and some of what we do know is cause for alarm. This is one of the main conclusions of a report released today by the National Research Council.

First, the headline picked up by the New York Times and others: there has been a rapid rise in weeds resistant to the herbicide glyphosate (also known as Roundup) that could rapidly undercut any environmental or economic benefits of GE crops. Glyphosate-resistant crops allow farmers to kill weeds with the herbicide without destroying their crop. To date, at least nine species of weeds in the U.S. have developed resistance to glyphosate since GE crops were introduced. The other primary type of GE crop is designed to produce Bacillus Thuringiensis (Bt), a bacteria deadly to insect pests. Thus far, two types of insects have developed resistance to Bt. The loss of effectiveness of glyphosate and Bt crops could lead to increased use of more potent herbicides.

"This problem is growing, it's real, and it's going to get worse," said chair of the NRS committee David Ervin, of Portland State University, at a press conference today.

But just as alarming as growing weed and pest resistance is the dearth of research data on so many fundamental issues surrounding GE crops. The NRC report focused on how GE crops are affecting U.S. farmers. The assessment looked at GE crops through the three pillars of sustainability: economic, environmental and social. In the end, the researchers didn't have enough data.

"As more GE traits are developed and incorporated into a larger variety of crops, it's increasingly essential that we gain a better understanding of how genetic engineering technology will affect U.S. agriculture and the environment now and in the future," said Ervin. "Such gaps in our knowledge are preventing a full assessment of the environmental, economic and other impacts of GE crops on farm sustainability."

More specifically, what we don't yet know about GE crops:

  • The full extent of weed resistance problems, or what those problems will mean in the future to the environment and farmers' bottom line.
  • Little understanding of how the use of GE crops affects water systems—positively or negatively.
  • The effects of GE crops on farmers not growing GE crops, including both conventional and organic farmers. The committee reported on anecdotal information that farmers have had trouble finding conventional non-GE seeds. And as Bob Scowcroft of the Organic Farm Research Foundation noted at the press conference, there is little peer-reviewed research on the enormous costs borne by organic farmers for testing to prove their crop is GE-free, let alone farmers who have lost organic certification from GE contamination.
  • The impact of consolidation in the seed industry—accelerated by the transition to proprietary GE seeds—on prices and seed choices.
  • Other social issues that have been overlooked include the impact of GE crops on labor dynamics, farm structure, farmer and community conflict and property rights.

The White House and USDA Secretary Tom Vilsack should take a good look at this report. After 15 years, we still can't fully assess whether GE crops are good for U.S. farmers—let alone consumers. Yet, the White House and Vilsack continue to aggressively push for other countries to use GE crops. As IATP's Dennis Keeney and Sophia Murphy wrote last month in the Des Moines Register, GE crops that are widely used in the U.S. don't make sense for the challenges facing Africa, for example.

Given the NRC report's findings, it's hard to justify the enormous amounts of money spent on the development of new GE crops, and harder still to justify pushing the technology on other countries, until we fill in the enormous research gaps that remain.
