Since the mid-1990s the biotech industry has claimed that genetic engineering (GE) would improve crop yields and help feed the world’s growing population, but a recently released report concludes “…that GE has done little to increase overall crop yields.”

The report, “Failure to Yield: Evaluating the Performance of Genetically Engineered Crops," was authored by Doug Gurian-Sherman, a senior scientist in the Union of Concerned Scientists (UCS) Food and Environment Program.

In a press release accompanying the report Gurian-Sherman stated,

The biotech industry has spent billions on research and public relations hype, but genetically engineered food and feed crops haven't enabled American farmers to grow significantly more crops per acre of land. In comparison, traditional breeding continues to deliver better results.

Recommendations

In light of the report, the Union of Concerned Scientists recommends government agencies and universities should redirect substantial funding, research, and incentives toward proven approaches that show more promise than genetic engineering. “These approaches include modern methods of conventional plant breeding as well as organic and other sophisticated low-input farming practices,” according to UCS.

UCS urges food-aid organizations to work with farmers in developing countries, where increasing local food production is urgent, and make “these more promising and affordable methods available.”

Scientists at UCS also assert, “Relevant regulatory agencies should develop and implement techniques to better identify and evaluate potentially harmful side effects of the newer and more complex genetically engineered crops. These effects are likely to become more prevalent, and current regulations are too weak to detect them reliably and prevent them from occurring.”

"If we are going to make headway in combating hunger due to overpopulation and climate change, we will need to increase crop yields," said Gurian-Sherman. "Traditional breeding outperforms genetic engineering hands down."

Funders

Funding for the report was provided by C.S. Fund, CornerStone Campaign, Deer Creek Foundation, The Educational Foundation of America, The David B. Gold Foundation, The John Merck Fund, Newman’s Own Foundation, Next Door Fund of the Boston Foundation, The David and Lucile Packard Foundation, and UCS members.
