Biofuel Surge Amid Oil Crisis Could Exacerbate Global Food Shortages
The Biofuel Demand Surge
Demand for biofuels is likely to leap by nearly a third this year as countries seek alternatives to expensive oil. The US, Indonesia, Brazil, Thailand and others have opted to increase biofuel use as the price of oil has jumped to nearly $100 a barrel after the US-Israeli attacks on Iran and the closure of the strait of Hormuz.
Projected Growth and Environmental Concerns
If oil supplies remain constrained, demand for biofuels could increase by 70% by 2030, according to estimates from the Transport & Environment (T&E) thinktank. Biofuels, from oil-bearing crops and grains, currently supply about 4% of the world's transport energy demand. Expanding biofuel production without competing with food crops for land and fertiliser would be difficult to achieve, and reaching 20% of global road fuel from biofuels would require an area the size of South Africa.
The Food Security Impact
The expansion of biofuels comes at a time when fertilizer supply has been constrained by the war and prices have soared, leading to rises in the price of staple foods for some of the poorest people in many parts of the world. Biofuels compete with food crops for land, while globally about one in every 20 tonnes of fertiliser is used to produce crops for fuel. In some countries it is a lot more: a tenth of fertiliser use in the US is for biofuels, and a fifth in Indonesia.
Historical Precedents and Future Projections
Though it is not possible to say exactly how far the expansion of biofuels could lift food prices, experts suggest it could be significant. In the food crises of 2007-08, the UN's Food and Agriculture Organization estimated that biofuel use contributed between 40% and 70% of the increase in maize and soya bean prices. The US is already forecasting that food prices will rise this year by between 2.2% and 4.7%, largely owing to the impacts of the war in Iran.
Sustainable Alternatives
Encouraging the switch to electric vehicles could reduce demand for biofuels, as generating renewable energy is a far more efficient use of land than growing crops for fuel. Solar panels covering just 3% of the land currently used for biofuel production would generate the same amount of energy, and because of the higher efficiency of electric vehicles, that would be enough to power a third of the global car fleet.
