Major genetically modified crop production countries, 2006
IAASTD/Ketill Berger, UNEP/GRID-Arendal
Some regions report increases in some crops and positive financial returns have been reported for genetically modified cotton in studies including South Africa, Argentina, China, India and Mexico. In contrast, the US and Argentina may have slight yield declines in soybeans, and also for maize in the US. Studies on GMOs have also shown the potential for decreased insecticide use, while others show increasing herbicide use.
