A weak U.S. dollar encouraged U.S. grain exports, and drove up petroleum prices expressed in dollars. Investors shifted funds from capital markets to commodity future markets causing commodity prices to rise sharply. While the ethanol boom influenced food prices, some of the increase in retail food prices could be attributed to the higher fuel costs for transportation of raw materials to the processing plants and food to the retail outlets.

Rapid economic growth in developing countries such as India and China over the past decade has increased demand for raw materials ranging from petroleum and steel to agricultural com- modities. When per capita income rises, countries experience a dietary transition with increased demand for animal protein which requires livestock feed such as corn and soybeans. The U.S. Energy Independence and Security Act of 2007 contains a renewable fuel standard with a target of 36 billion gallons by 2022 (Fig. 6). The conventional biofuel category encompassing ethanol from corn grain is mandated to increase to 15 billion gallons by 2015 and remain at that level. Except for modest amounts of biodiesel from vegetable oils such as soybean oil, most of the rest

Although higher food prices do adversely impact high-income consumers, those who spend 15% or less of their income on food experience a much less severe impact from food price increases than those who spend 25-50%. Expenditures on food consumed at home in 2007 in the United States were only 5.7% compared to 8.6% in the United Kingdom, 11.4% in Germany, 13.7% in France, 14.5% in Italy, 14.6% in Japan, 24.6% in Brazil, 28.7% in Russia, 32.4% in India, 34.9% in China, 38.8% in Egypt and 45.7% in Pakistan [5]. Hence, even though the impact of the increased The sharp rise in commodity prices in global markets in 2008 was a double-edged sword for developing countries. For market-oriented farmers, in contrast to subsistence farmers, this increased their income. However, for low-income consumers, especially in urban areas, who are dependent on the market for their food, increases in food prices had a negative impact. The impacts of higher food prices are especially severe for low-income consumers because they often spend from 25% to 50% of their disposable income on food.

Increases in area planted and yields have contributed to the availability of corn for ethanol production in the United States. To satisfy this surge in demand for corn for ethanol, the proportion of corn destined for export and domestic livestock feed has declined. Von Braun [14] provides a perspective on the impacts of food price increases on developing countries. Higher food prices cause the poor to limit food consumption. This can result in under- nutrition and adverse health impacts, especially for children who are already at risk. Ivanic and Martin [15] further note that food price increases in 2008 probably increased overall poverty in low- income countries. U.S. corn production and usage by category.
