Take maize (corn, to Americans) which is used both to make ethanol and to feed livestock.
Maize (corn), tomatoes, beans, potatoes and much else became staples throughout the world.
In the fields, in the shadow of giant billboards giving motivational advice or productivity targets, women in headscarves bend over crops of maize, corn and rice.
Also in Germany, there are aerobic digesters which are fed by maize (corn) rather than waste and so the same argument would arise over growing crops for fuel or for food as applies to biodiesel production and must ring an eventual death-knell for both biodiesel and biogas, if the latter is made from food too.

By March 1988, the government owned a vast 1.8 billion bushels of corn (maize), roughly a year's supply.
Meanwhile, the relative price of corn (maize) to rice, which is much more favoured, has jumped by half.
Favoured commodities such as corn (maize), wheat, soyabeans and cotton will receive a per-acre revenue guarantee of about 90% of the previous five years' returns.
But this year the primary corn (maize) and soyabean agricultural belt has been hard hit by the drought of the past three months: crops, pastures and rangeland have deteriorated at a rate rarely seen in the past 20 years.
It wants the amount of the stuff used as transport fuel to climb from 13 billion gallons (49 billion litres) in 2010 to 36 billion gallons in 2022, requiring by far the largest part of that increase to come from various advanced biofuels, rather than ethanol made from corn (maize).
Growers of popcorn maize are fighting to get the same support as field corn.
According to Julie Major, of the International Biochar Initiative, a lobby group based in Maine, infusing savannah in Colombia with biochar made from corn stover (the waste left over when maize is harvested) caused crops there to tower over their char-less peers.
ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well
