I'll make one comment about drought-tolerant crops, and it relates to research that's been done before. I actually have a grad student dealing with marker-assisted research into drought-tolerant crops and GM crops. One of the things we get out of this, which we often get out of returns to research studies, is that when you have a relatively large increase in production without a corresponding reduction in cost--and in these cases you wouldn't have a reduction in cost--then when prices go down sufficiently, the effect at the end of the day is that producers end up losing money or not being any better off. The ones who come in as first movers take advantage of the situation, but the majority of the sector do not.
With regard to a lot of these technological innovations, I would caution you that you have to think very carefully about what they will do at the end of the day with respect to price impacts.
