 Yaneer Bar-Yam, the president of the New England Complex Systems Institute, said that computer modelling suggested an outbreak of instability, while he also blamed the use of corn for ethanol as exacerbating the problem.However, the director of trade and markets and the Food and Agriculture Organization, David Hallam, said that there was no imminent danger of such an outcome, though a worsening change in climate and government policies, such as export bans and panicked-buying, could trigger such a scenario.Oxfam added that a one percent increase in the price of food could lead to 16 million more falling below the poverty line.
