GMO Crops Failure to Yield
For years the biotechnology industry has trumpeted that it will feed the world, promising that its genetically engineered crops will produce higher yields.
That promise has proven to be empty, according to Failure to Yield, a report by Union of Concerned Scientists expert Doug Gurian-Sherman released in March. Despite 20 years of research and 13 years of commercialization, genetic engineering has failed to significantly increase U.S. crop yields.
Failure to Yield is the first report to closely evaluate the overall effect genetic engineering has had on crop yields in relation to other agricultural technologies. It reviewed two dozen academic studies of corn and soybeans, the two primary genetically engineered food and feed crops grown in the United States.
Based on those studies, the UCS report concluded that genetically engineering herbicide-tolerant soybeans and herbicide-tolerant corn has not increased yields. Insect-resistant corn, meanwhile, has improved yields only marginally.
The increase in yields for both crops over the last 13 years, the report found, was largely due to traditional breeding or improvements in agricultural practices.
The UCS report comes at a time when food price spikes and localized shortages worldwide have prompted calls to boost agricultural productivity, or yield -- the amount of a crop produced per unit of land over a specified amount of time. Biotechnology companies maintain that genetic engineering is essential to meeting this goal. Monsanto, for example, is currently running an advertising campaign warning of an exploding world population and claiming that its “advancedseeds…significantly increase crop yields.” The UCS report debunks that claim, concluding that genetic engineering is unlikely to play a significant role in increasing food production in the foreseeable future.
In addition to evaluating genetic engineering’s record, “Failure to Yield” considers the technology’s potential role in increasing food production over the next few decades. The report does not discount the possibility of genetic engineering eventually contributing to increased crop yields. It does, however, suggest that it makes little sense to support genetic engineering at the expense of technologies that have proven to substantially increase yields, especially in many developing countries. In addition, recent studies have shown that organic and similar farming methods that minimize the use of pesticides and synthetic fertilizers can more than double crop yields at little cost to poor farmers in such developing regions as Sub-Saharan Africa.
The report also recommends that U.S. food aid organizations make these more promising and affordable alternatives available to farmers in developing countries.
