During Lucy’s tour, we had a few questions about the yield of GE crops. A comprehensive review of the literature had the following to say:
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 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.
