The UN special rapporteur on the right to food, Jean Ziegler, has recently made the headlines by claiming that the planting of crops to produce biofuels instead of food constitutes a “crime against humanity” because it results in a scarcity of food, driving up prices beyond what the poor can afford. In the past year, poor harvests, rising oil prices and a surge in demand for food from China and India have all contributed to substantial rises in food prices globally.
In Australia, Mr Ziegler’s comments appeared less compelling, because they were reported in the context of Australia’s sugar crop, which has in recent years been in oversupply. The use of Australian sugar to produce biofuel seems unlikely to have any adverse effect on world food prices. On the other hand, the diversion of current food crops in Africa and Asia to biofuel production would create obvious food supply problems.
The question of whether the world can produce enough food to feed everyone is not a new one. In 1798 Thomas Malthus famously predicted that increases in population would lead to mass starvation. Since then the world population has increased by 600%, but food production efficiency has increased even more.
