By Bob Bartley, grain farmer based at Roland, Manitoba.
I have been a farmer for 40 plus years and I have grown genetically enhanced (GE) crops since 1996. We grow corn, soybeans and canola, all of which are GE as well as other crops which are not. I have seen many benefits to this technology through the years, but what is in it for the consumer?
I really don’t consider the crops I grow to be ready-to-eat food, like apples, carrots or potatoes, but more like ingredients to make food products such as margarine, flour and feed for livestock. Government regulators and scientists have questioned the safety of GE crops right from the beginning. As a result, these crops have undergone testing far beyond that required for other new varieties. There have been about 2,000 published studies on GE crop safety, I’m told. The results say that the GE crops now grown are as safe as any others. Some reports say even safer. There have also been several studies showing that they reduce food prices too-a direct result of the higher farm yields. GE crops are one reason why North American consumers have the safest, highest quality and most affordable food in the world.
The adoption of higher yielding GE crops has allowed farmers to grow more without using additional land. Every day, cities grow larger on some of the most productive soils in the world. Every day the world’s population increases. Farmers are tasked to produce more food on fewer acres and it’s not something we can do on our own. Farmers need the help of innovative plant breeding tools to increase the capability of the crops we grow – innovations that increase production and allow our harvests to be used in many different ways to provide food for you and me.

The discovery of the herbicide glyphosate and glyphosate-tolerant crops changed agriculture. They have allowed farmers to control perennial weeds in crops instead of depending on summer-fallowing, which requires no crop to be produced for an entire year. Also, with the new technology, the crop stubble remaining after grain harvest is undisturbed and this allows for more moisture retention and reduced soil erosion due to wind and water. There is less fuel used on the farm because of the reduced soil tillage.
Insects have always been a threat to our crops and thus to our livelihood. The Bt gene in the corn we grow, gives the crop resistance to the European corn borer. In earlier years, we used insecticides to kill the borer but they also killed beneficial insects such as lady bugs. Bt is pest specific and only kills the corn borer. Insecticide is not applied now which saves another trip across the field.
Farmers have always been stewards of the land using the tools available to them. We strive to leave our land with the same or increased production capability compared to when we started farming. Carbon sequestering in farm soils, through no-till and reduced tillage, results in a reduction of green house gas (CO2) levels in the atmosphere.
What’s in it for the consumer? Society’s buying habits have leaned towards being environmentally friendly and sustainable. So here it is! Better air and water quality due to reduced erosion and reduced tillage. Fewer pesticides applied and less fossil fuel consumption resulting in lower greenhouse gases. Drought-resistant crops that produce with more efficient use of water. Protection of beneficial insects. It turns out that what’s good for me as a farmer is also good for you the consumer. Some call that win-win.
