Are GE Crops part of aSustainable Future? Robert Wager Vancouver Island University
The Problem A billion people experience hunger and another billion lack essential vitamins and minerals in their diet The global population is predicted to be 9 billion by 2050 FAO 2010
North American Adoption of GE Crops • >90% Soy • 70% Corn • 98% Sugar beet • 95% Canola
Indian Experience The environmental and human health benefits from adopting Bt cotton have also been extensively documented. • 24% increase in cotton yield per acre • 50% gain in cotton profit among smallholders • Triple yield from 2002 (first year of Btcotton) • Over 90% of all Indian cotton is Bt today
Australian Experience BollgardII® accounts for up to 95% of cotton planted in Australia and its adoption has resulted in a decrease of 85% in the amount of conventional insecticides used during cotton production
GM Crop Adoption Reduces Pesticide Use and Environmental Impact (1996-2009) 1996 2009 8.7% 17.1% *Values are for biotech crop areas only, not total global cropping area – GM crops account for ~10% of total global cropping area Source: Brookes and Barfoot (2011) GM Crops: Global Socio-Economic and Environmental Impacts 1996-2009.

Global Scientific Opinion “The WHO, the AMA, the U.S. NAS, the British Royal Society, and every other respected organization that has examined the evidence has come to the same conclusion: Consuming foods containing ingredients derived from GM crops is no riskier than consuming the same foods containing ingredients from crop plants modified by conventional plant improvement techniques.” • (AAAS 2012)
Controversies about the impact of genetically modified (GM) crops have too often been based on contested science EASAC 2013
Royal Society Rebuke of Pusztai1999 GM potato paper • “The reported work from the Rowett is flawed in many aspects of design, execution and analysis and that no conclusions should be drawn from it.” • “Found no convincing evidence of adverse effects from GM potatoes.”

Diet with maize (transgenic vs. conventional isogenic) Control group In some cases high doses seems to be protecting. In other cases, they are less harmful than lower doses! Fig. 1. Mortality of rats fed GMO treated or not with Roundup. Rats were fed with NK603 GM maize at three different doses (11, 22, 33% in their diet: thin, medium and bold lines, respectively) compared to the substantially equivalent closest isogenic non-GM maize (control, dotted line). Lifespan during the experiment for the control group is represented by the vertical bar ± SEM (grey area). In bar histograms, the causes of mortality before the grey area are detailed in comparison to the controls (0). In black are represented the necessary euthanasia because of suffering in accordance with ethical rules (tumors over 25% body weight, more than 25% weight loss, hemorrhagic bleeding, etc.); and in hatched areas, spontaneous mortality.
European Research Swiss NSF (2012), reviewing more than 2000 studies, No health or environmental risks Italian Study (2013) reviewed 1783 studies No health or environmental risks
European National Academies of Science (2013) There is no validated evidence that GM crops have greater adverse impact on health and the environment than any other technology used in plant breeding. EASAC 2013
Safety Record 17 years, >3,000,000,000,000 meals containing ingredients from GE crops Zero documented cases of harm
The next “Big” players Countries not Corporations Brazil, Chinaand India • Over 70 countries have active Biotechnology R&D programs
The Next Generation of GE Crops • Micro-nutrient enhanced Iron, Zinc, Vitamin A • Fungal resistance-wheat, potato, banana • Viral resistance-many crops • Bacterial resistance-banana, grapes, orange • Enhanced Nitrogen efficiency • Drought tolerance • Salt tolerance • Frost tolerance • Pharma crops
