The Organization for Economic Co-operation and Development (OECD) and the United Nations Food and Agriculture Organization (FAO) have issued a stark forecast: by 2034, 27% of global cereal production will be consumed by the biofuel and industrial sectors. This projection intensifies a long-simmering debate about the balance between food availability and alternative energy demand.

Most notably, 37% of the world's corn supply is expected to be rerouted to non-food purposes-15% of it to biofuel alone. While wheat and rice will still primarily feed populations, corn is at the center of this shifting dynamic.

The implications are just as dramatic for vegetable oil. By 2034, only 52% will be allocated to food, while 18% will go to biomass-based diesel, according to the report. Despite slowing growth in biofuel consumption, demand remains high. Global ethanol production is projected to reach 155 billion liters, while biomass-based diesel climbs to 80.9 billion liters by 2034.

Analysts are divided on the urgency of these trends. Marlene Boersch, managing partner at Mercantile Consulting Venture, suggests this issue will resurface quickly if weather or geopolitical events disrupt major crop outputs.

"That debate will double up the second that commodity prices recover because somewhere there is a crop problem," Boersch stated. For now, falling commodity prices driven by sufficient global production have kept concerns at bay.

But the fragile balance could easily tip. "The second that happens, and people start talking about shortages, we'll talk about the use in biofuels," she added.

Others are more skeptical of long-term forecasts. Errol Anderson, author of Errol's Commodity Wire, dismisses projections looking a decade ahead. "We can't see six months forward... They're talking 10 years from now. Are you kidding me?"

Indeed, the OECD/FAO report acknowledges the high uncertainty in its projections. Shifting government policy, changing feedstock availability, and volatile fossil fuel prices complicate long-term predictions.

While demand is expected to grow, the pace of biofuel expansion is slowing. Both production and consumption are projected to rise just 0.9% annually through 2035-a fifth of the rate observed in the previous decade. Reduced policy support in developed nations and declining global fuel demand are key factors.

The International Energy Agency forecasts that global gasoline-type fuel demand will drop by 0.8% per year, driven by electric vehicle (EV) adoption, fuel efficiency improvements, and petrochemical competition.

Still, corn and vegetable oil will remain the backbone of biofuel feedstocks. Corn is expected to make up 60% of ethanol production inputs, while vegetable oil will contribute 70% of biomass-based diesel. Biofuel-driven consumption of vegetable oil will grow at 0.7% annually, a steep drop from the 7.7% annual growth seen during the height of government support.

With such significant portions of food crops diverted to energy use, U.S. ag professionals must stay alert to shifting policy landscapes and market demands. Whether the world can sustainably balance energy innovation with food security remains one of the defining agricultural challenges of the next decade.
