'Peak Farmland' Is Here, Crop Area to Diminish

10. Or even plateau

There is some slight common sense to what he is saying, but I don't think that they are fully considering what it would entail. In order to make low-yield land in 3rd world countries increase yields significantly, they would likely rely on developed nations' farming practices: heavy machinery, evasive soil management, water-intensive irrigation, petro-derived fertilizers, etc. So, what are the secondary implications of engaging in a second "green revolution" as far as our environment is concerned (and how will those consequences reciprocally impact future yields globally?).

I don't think a study about future agriculture that doesn't account for the ecological impact of climate change can be taken seriously. I find it suspect that this study is so widely reported upon.
