Buddhist Economics and A GMO rethink

“Wisdom demands a new orientation of science and technology towards the organic, the gentle, the non-violent, the elegant and beautiful.”

- E. F. Schumacher, Small Is Beautiful, 1973

images-4Discussions about plant genetic engineering often reflect two starkly opposing narratives. On the one side are the angry mobs who invade research farms to destroy fragile green rice seedlings deemed “GMOs”. On the other, are the scientists who call for calm and respect for publicly funded research. Too often, it seems, there is little mutual understanding.

But times may be changing.

In a forum yesterday hosted by the Boston Review Magazine, a group of  journalists, activists, plant biologists, and farmers as well as academic experts in food security, international agricultural and environmental policy sat around a virtual table to find common ground. All accepted the broad scientific consensus that the process of GE does not pose inherent risks compared to conventional approaches of genetic alteration and that the GE crops currently on the market are safe to eatand safe for the environment. That agreement allowed the discussion to move forward to a more societally relevant issue- the use of appropriate technology in agriculture.

Few consumers question the utility of reading Scientific American’s Food Mattersonline or using the most efficient technology to do it. Yet many are hesitant to embrace technology when it comes to food and farming. Some find the use of plant genetic engineering (GE), a modern form of plant breeding particularly distasteful.

Yet GE is just one of many technologies used to alter the genetic makeup of our crops. Today virtually everything we eat is produced from seeds that have been genetically altered in some manner.

Conventional methods include grafting or mixing genes of closely related species through forced pollinations, as well as radiation treatments to induce random mutations in seeds.  Such approaches are imprecise, resulting in new varieties through a combination of trial and error, without knowledge of the function of the genes affected.

GE introduces one to few well-characterized genes resulting in fewer genetic changes. In contrast to most conventional approaches, GE allows for introduction of genes from distantly related species, such as bacteria. Over the last twenty years, scientists and breeders have used both conventional and GE technologies to create crop varieties that thrive in extreme environments or can withstand attacks by pests and disease.

What criteria can scientists, farmers and consumers use to assess which type of these genetic technologies is most appropriate for agriculture?

In his 1973 book Small is Beautiful, economist E. F. Schumacher states that an appropriate technology should be low cost, low maintenance and promote values such as health, beauty, and permanence. Environmentalist Stewart Brand used a similar framework to select new technologies for inclusion in his 1969 Whole Earth Catalog. One of the purposes of the Whole Earth catalog was to facilitate a creative or self-sustainable lifestyle.

We can apply Brand and Schumacher’s Buddhist economic criteria to evaluate modern agricultural technologies.

Take, for example, Golden Rice, a provitamin A–enriched rice developed through genetic engineering that comprises many of the properties advocated by Schumacher and Brand. Consumption of Golden Rice, within the normal diet of rice-dependent poor populations, could provide sufficient vitamin A to reduce substantially the 6,000 deaths caused every day by vitamin A deficiency and save the sight of several hundred thousand people per year. This “biofortification” approach is important to poor farmers and their families in developing countries who lack nutrients and cannot pay the price of improved seed. It is widely considered an improvement on conventional supplementation programs, such as the World Health Organization’s distribution of Vitamin A pills, which costs 40 times more and often does not reach the rural poor who have little access to roads.

Golden Rice is an excellent example of how a particular genetic technology can appropriately serve a specific societal purpose – in this case, enhancing the health and well-being of farmers and their families. It is a relatively simple technology that scientists in most countries, including many developing countries, have perfected. The product, a seed, requires no extra maintenance or additional farming skills. The seed can be propagated on the farm each season at no extra cost through self-pollination and improved along the way.

Can we conclude from the example of Golden Rice that all GE seeds fall into the category of appropriate technology? Unfortunately it is not that simple. Each agricultural technology must be evaluated on a case-by-case basis.  It is not informative to group all “GMOs” together without regard to the purpose of the engineering, the needs of the farmer, or the social, environmental, economic, or nutritional benefits.

This central point is addressed by several participants in the Boston Review forum. Journalist Marc Gunther highlights the conspiratorial narrative about GE technology favored by some corporate supported anti-GMO activists. Greg Jaffee, Director of Biotechnology at the Center for Science in the Public Interest points out that better farm management is crucial  to ensure that future GE crops benefit farmers, consumers and the environment. Margaret Mellon, Senior Scientist at the Union of Concerned Scientists argues that GE is not a transformative technology.Rosamond Naylor, Director of the Center on Food Security and the Environment at Stanford University discusses the ethics of GMOs in light of persistent hunger and malnutrition. Robert Paarlberg, author of Food Politics: What Everyone Needs to Know outlines the effectiveness of anti-GMO campaigns in blocking the use of modern technologies in the developing world. Nina Fedoroff, Professor of Biology at Pennsylvania State University and former President of the American Association for the Advancement of Science describes the pervasive disconnect between what is true and what people believe to be true about GMOs. Tim Burrack, Farmer and Vice Chairman of Truth About Trade and Technology  gives an account of today’s farmers who are growing more food on less land than ever before using biotechnology as an essential ingredient. Jennie Schmidt, Farmer and registered dietician reports that farmers choose GE crops because they are economically and environmentally advantageous.  Jack Heinemann, Lecturer in Genetics at the University of Canterbury reminds us that reliance on seed technology alone will not avert agricultural catastrophes. Their commentaries are posted online (just click on names to view each one) and the entire forum will be available in print form in the September Issue of the magazine. Kudos to Boston Review’s editor Deborah Chasman and Managing Editor Simon Waxman for launching this forum.

One unusual and important aspect of the forum compared to many other discussions on GE crops is that it was science-based, critically reviewed and included the perspectives of farmers –the 1% of US workers that actually produce the food that the rest of us eat and who are at the forefront of evaluating the effectiveness of specific agricultural technologies.

Despite the massive number of technical reports attesting to the safety and environmental benefits of GE crops over the pasts decade, science-based information about food, farming and genetics has only trickled out to the public through government agencies and science-based blogs such as Biofortified.orgUcbiotech.org,Academicsreview.org. Recently, however, to the delight of plant biologists, farmers, food security experts and skeptics, this trickle has turned into a torrent of excellent reporting.

Consider for example the investigative reporting by a bevy of talented journalists such as New York Times Pullitzer Prize winning author Amy Harmon, DotEarth’s Andy Revkin, Slate’s Daniel Engberthe New Yorker’s Michel Specter, Grist’s Nathaneal Johnson, Discover magazine’s Keith Kloor, Greenwire’sPaul Voosen, and Genetic Literacy Project’s Jon Entine. All have tackled the science behind GE crops eloquently and accurately. A number of informative and entertaining books on the subject have been published over the last few years as well. See for example, Stewart Brand’s Whole Earth Discipline, Michael Specter’sDenialism, and James McWilliam’s Just Food.

As more information is made available demystifying what farmers and plant breeders actually do, the public dialog about GE crops is becoming more sophisticated. Even chefs are taking time out of the kitchen to reevaluate their stance on modern agricultural technologies. Mark Bittman, widely admired for his culinary skills (check out his practical lunch tips) and beautiful prose, recently visited one of my neighbors here in the Central Valley (the source of 50 % of U.S. fruits, nuts and vegetable) to learn about tomato farming. He wrote an unusuallythoughtful and respectful piece on the approaches the Rominger farm in Winters is taking to advance ecologically based management practices using modern technologies.

images-3What technology then is truly “appropriate” for agriculture? There is no simple answer to this question. Instead of focusing on how a seed variety was developed, we need to frame discussions about agriculture in the context of environmental, economic, and social impacts—the three pillars of sustainability. We must ask what most enhances local food security and can provide safe, abundant, and nutritious food to consumers. We must ask if rural communities can thrive and if farmers can make a profit. We must be sure that consumers can afford food. And finally we must minimize environmental degradation. This includes conserving land and water, enhancing farm biodiversity and soil fertility, reducing erosion, and minimizing harmful inputs. The most appropriate technology for addressing a particular agricultural problem depends on the context.

Technology evolves. Just as today we source tools through the internet rather than the Whole Earth Catalog (Steve Jobs called the Whole Earth Catalog “Google in paperback form”), few breeders now rely on primitive domestication for seed production.

As the physicist and philosopher Jacob Bronowski pointed out fifty years ago, “We live in a world which is penetrated through and through by science and which is both whole and real. We cannot turn it into a game by taking sides. . . . No one who has read a page by a good critic or a speculative scientist can ever again think that this barren choice of yes or no is all that the mind offers”.

  • John R, Diaz

    Pamela, can we cut to the chase? let me add to your article with a quote from:
    Robert Frawley, Co President of Monsanto Agriculture Sector in regards to GE Crops:
    “What you are seeing is not just a consolidation of seed companies it’s really a consolidation of the entire food chain.”

    So the question is how do you scientifically sugar coat the word MONOPOLY? GE Agriculture is a monopoly of agriculture. Plain and simple!

    • Keith Hayes

      Well lets keep in mind that Monsanto isn’t the only player in the food supply chain. Hundreds of corporations contribute to the production and distribution and sale of food on a global scale. That doesn’t just mean the technology involved, but many independent farmers, good manufacturing practices, quality controls and supermarkets that allow me to buy the food at my own convenience. I hardly see a monopoly here. If anybody objects to this model, they are welcome to grow and produce their own food.

      For one, I like the sense of optimism I get from the article that people from many disciplines are recognizing the utility and positive gains from GE of crops (and animals. Aquabounty? Where are you?) and willing to communicate that to others. The discussion has been dominated by the wrong people for a long time.

    • Wouldn’t it be great if there were more small research groups and small companies getting their ideas and terrific plants out into the world?

      I gave money to the ones developing the Glowing Plants on Kickstarter. And I plan to make THC mint and oregano in my basement for a retirement project.

      What do you do about it? Do you support open source GMOs and groups that are working on that sort of thing John?

      « GE Agriculture is a monopoly of agriculture. Plain and simple! »?

      GE agriculture is essentially limited to canola, corn, cotton, and soy in some two dozen countries. Whilst there a a handful of big players – corporations which have developed their own production base and, more importantly, acquired seed companies and developed their strength on in great measure on their basis – they are by no means alone, even on the GE market.

      When you read that the top 10 companies control 75.3 % of the global market, you must bear in mind that that « market » represents a small fraction of the seed supply. These figures are not indicative of a monopoly.

  • Margaret Mellon

    As a participant in the Boston Review Magazine forum, I take issue with the sweeping statement that all of the participants agreed that the GE crops currently on the market are safe to eat and safe for the environment. My views on both topics are more nuanced.

    I agree that GE products currently on the market–overwhelmingly herbicide tolerant (HT) and BT crops–are unlikely to be allergenic or toxic and on that basis are likely safe to consume. But I also believe that there are holes in the risk assessment process that leave some questions unanswered. This month’s issue of Nature Biotechnology has an excellent feature discussing the challenges of food safety testing.

    Moreover, it is important to note that each GE product must be individually assessed for food safety and that the safety status of the HTC and BT crops says little about foods that might be introduced in the future. For example, serious attention needs to be paid to the possibility that GE products produced by gene silencing might inadvertently turn off non-target genes in people who consume them.

    I disagree strongly with the statement that the BT and HT crops are safe for the environment. Yes, scientists have documented pesticide reductions in pesticide use immediately following the introduction of these crops, which I welcome and applaud.
    But these benefits exist only until resistance develops to glyphosate or the BT toxins.
    Glyphosate-resistant weeds have already arisen across the US and are leading to enormous increases in pesticide use, reversing the early reductions attributable to the HT crops. The biotechnology industry’s response is a new generation of transgenic crops that enable the use of older, more herbicides like 2,4 D and dicamba. Unless U.S. agriculture responds swiftly, we will soon be facing a nightmare scenario of increased pesticide use resulting from resistant weeds. This is not an example of an environmentally beneficial technology.

    BT has proven much more durable, in part because strong regulations allowed the government to impose refuge requirements on U.S. farmers. But resistance has already arisen in corn root worms in the Midwest and is leading to increased chemical insecticide use.

    • Keith Hayes

      What “holes” in the risk assessment process do you see, Margaret?

      Also the risks that you discuss aren’t any different then risks we faced before the introduction of GE crops; particularly pesticide and herbicide resistance. The reason why so many people praise the GE crops is because such crops had made it possible to manage these risks in a more environmentally friendly manner.

  • Mlema

    Hi Keith,

    If you have some time to read the following, i think it might answer your question to some extent. Our current risk assessment for GMOs is not adequate to the task of identifying possible problems. Safety assessment is left to the producers, and the FDA, EPA and USDA provide, at best, a patchwork of regulations – not reflective of the health or environmental risk. In spite of the general sentiment expressed here, transgenics are not the same as conventionally bred.

    • Keith Hayes

      The link from the Union of Concerned Scientists isn’t mentioning any additional risks that haven’t already been considered by researchers and regulatory authorities. As an example, development of GMO’s that have ended up expressing known allergens have ceased. And any new, novel chemicals are characterized to determine toxicity. So it seems the regulatory process is working and there are no holes that have been identified up until this point. Increased weediness has more to do with weeds developing a resistance to herbicides rather than the GM crops themselves. I don’t know if the gene for antibiotic resistance is used in development anymore, but I imagine it gets bread out when the modified plant gets crossed with existing cultivars anyways.

      They refer to “unknown risks” but unless they identify a risk that hasn’t been considered, there isn’t much to do about this statement.
