I think measuring the impact of innovation is a real challenge, because innovation happens over such long period of time. It almost happens in a matter of decades. It is hard to track the investments we made in Going Forward 2 directly to the impacts we're seeing.
That said, we've been doing innovation work and science work for a long time and we are starting to see the impacts. There are various studies that have been done that show that the rates of return of R and D in agriculture are quite high, and there are multiple impacts.
We started to do it through case studies. The canola industry is a $19-billion industry now, but if you go back two decades, there was no canola industry. Through investments in science and research at Agriculture Canada and other places, we are starting to see those impacts. We certainly try to measure globally, but we also look at case studies to show the impact.
