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 UCS expert Doug Gurian-Sherman (http://www.ucsusa.org/news/experts/doug-gurian-sherman.html) released in March 2009. 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.
