A REPORT by the National Research Council last month gave ammunition to both sides in the debate over the cultivation of genetically engineered crops. More than 80 percent of the corn, soybeans and cotton grown in the United States is genetically engineered, and the report details the “long and impressive list of benefits” that has come from these crops, including improved soil quality, reduced erosion and reduced insecticide use.
It also confirmed predictions that widespread cultivation of these crops would lead to the emergence of weeds resistant to a commonly used herbicide, glyphosate (marketed by Monsanto as Roundup). Predictably, both sides have done what they do best when it comes to genetically engineered crops: they’ve argued over the findings.
Lost in the din is the potential role this technology could play in the poorest regions of the world — areas that will bear the brunt of climate change and the difficult growing conditions it will bring. Indeed, buried deep in the council’s report is an appeal to apply genetic engineering to a greater number of crops, and for a greater diversity of purposes.
Appreciating this potential means recognizing that genetic engineering can be used not just to modify major commodity crops in the West, but also to improve a much wider range of crops that can be grown in difficult conditions throughout the world.
Doing that also requires opponents to realize that by demonizing the technology, they’ve hindered applications of genetic engineering that could save lives and protect the environment.
Scientists at nonprofit institutions have been working for more than two decades to genetically engineer seeds that could benefit farmers struggling with ever-pervasive dry spells and old and novel pests. Drought-tolerant cassava, insect-resistant cowpeas, fungus-resistant bananas, virus-resistant sweet potatoes and high-yielding pearl millet are just a few examples of genetically engineered foods that could improve the lives of the poor around the globe.
For example, researchers in the public domain have been working to engineer sorghum and maize crops for resistance to both drought and an aggressively parasitic African weed, Striga. Sorghum and maize are staples throughout Africa, so improved seeds would be widely beneficial.
As well as enhancing yields, engineered seeds can make crops more nutritious. A new variety of rice genetically engineered to produce high amounts of provitamin A, named Golden Rice, will soon be available in the Philippines and, if marketed there and more widely, would almost assuredly save the lives of thousands of children suffering from vitamin A deficiency.
There’s also a sorghum breed that’s been genetically engineered to produce micronutrients like zinc, and a potato designed to contain greater amounts of protein.
To appreciate the value of genetic engineering, one need only examine the story of papaya. In the early 1990s, Hawaii’s papaya industry was facing disaster because of the deadly papaya ringspot virus. Its single-handed savior was a breed engineered to be resistant to the virus. Without it, the state’s papaya industry would have collapsed. Today, 80 percent of Hawaiian papaya is genetically engineered, and there is still no conventional or organic method to control ringspot virus.
The real significance of the papaya recovery is not that genetic engineering was the most appropriate technology delivered at the right time, but rather that the resistant papaya was introduced before the backlash against engineered crops intensified.
Opponents of genetically engineered crops have spent much of the last decade stoking consumer distrust of this precise and safe technology, even though, as the research council’s previous reports noted, engineered crops have harmed neither human health nor the environment.
In doing so, they have pushed up regulatory and development costs to the point where the technology is beyond the economic reach of small companies or foundations that might otherwise develop a wider range of healthier crops for the neediest farmers. European restrictions, for instance, make it virtually impossible for scientists at small laboratories there to carry out field tests of engineered seeds.
As it now stands, opposition to genetic engineering has driven the technology further into the hands of a few seed companies that can afford it, further encouraging their monopolistic tendencies while leaving it out of reach for those that want to use it for crops with low (or no) profit margins.
The stakes are too high for us not to make the best use of genetic engineering. If we fail to invest responsibly in agricultural research, if we continue to allow propaganda to trump science, then the potential for global agriculture to be productive, diverse and sustainable will go unfulfilled. And it’s not those of us here in the developed world who will suffer the direct consequences, but rather the poorest and most vulnerable.
