Genetic engineering has been hailed as a panacea for the problem of global hunger and population explosion, but research studies reveal that it has failed to deliver the goods. At the same time, it has created more problems than it could solve. The Union of Concerned Scientists, an international research group based in the US, said none of the genetically engineered crops under cultivation so far has boosted farm yield or overcome the problem of drought conditions. ”Genetic engineering has actually done very little to increase the yield of food and feed crops. It appears unlikely that this technology will play a leading role in helping the world feed itself in the foreseeable future,” said the Union of Concerned Scientists. In a document — Failure to Yield — released at the CoP-11, the research group reviewed the data on soybeans and corn, the main GE food/feed crops in the USA.
