I looked at the editors note heading it, and it seems the article is a 
treatise on an argument I have heard here in the UK, that converting 
existing food producing farmland to ethanol producing crops is a bad way to 
go. HOWEVER there are crops suitable for producing ethanol that will grow 
quite satisfactorily on ground that is too poor to grow food producing 
crops, in arid areas, and my understanding of the argument is that these 
areas should be put to this use, rather than food producing farmland.

I don't have any references to documents on this, but may find some time to 
try and track some down.
