Global food prices have more than doubled over the past decade, reaching record highs in 2007-8 and 2010-11 (Figure 7.3). International prices for corn, wheat and rice more than doubled between 2006 and 2008. While prices declined in late 2008, food prices then rebounded, attaining new record highs in February 2011. Despite conflicting evidence, it would appear that recent price increases have also been accompanied by higher volatility, which increases uncertainty, thereby hindering investment in human and physical capital, technology, and innovation (FAO, 2009).
