One of the other areas is taking a look at the research on the innovation side and trying to get more income from the same crops. Agriculture waste presents some opportunity for generating energy, whether it be in livestock farms or grain farms. I think we have to start looking at how we can pull more dollars out of that same acre or hectare of land. That's going to be based on having good research ahead of time and doing pilot projects to see how we can maximize the return in agriculture. One of the things we are starting to see is a number of livestock farms putting in methane digesters and things like that, which have the benefit of not only dealing with the climate change issue, but also increasing the revenue of that farm, so the overall profitability goes up.
I still think ongoing research is going to be needed on the productivity side as well. Some of the gains that we've seen in crop yields over the last number of years are the result of research that was done 20 or 30 years ago. I think that type of research has to continue. The cluster model, as I mentioned in the presentation, seems to be working.
