Quinoa is an ancient grain- has all the Amino acids, so its the perfect grain for food aid relief- cooked, it has the aroma of baked potato:Best of all, since it originated from South America,( Mexicans/Aztecs)it is a suitable grain for warmer climates.
I agree, on the US farmland issue, but we have very few affordable options right now, so until we can get ethanol from non-edible plants ( still being developed, 5 years approx)
Corn is the best alternative bio fuel.
