I've heard of rice burners...but... Seriously- this is a cross pollination of issues which have little to no relation.
The rice "shortage" is enough to raise prices- significantly- based on food prices historically (which have fallen, and fallen and fallen for generations as a percentage of income), but the level of the shortage does not rise to the level of an actual shortage of food where none can be had at any price. Where that may be the case (outside the U.S.), it is due to political issues, not agricultural. Do droughts come and bad years, sometimes several in a row occur? Of course they do and they always have and always will.
As for the fuel issue- I've said it before, I'll say it again: to abort the bio-fuel industry at this stage based only upon present technology and present shortcomings (real or perceived based on biased “studies”) would be a huge mistake. Corn is not the only thing which can be made into ethanol. As one example, cellulosic ethanol from perennial grasses has the potential to be very effective and efficient. There are also other technologies on the horizon.
