The decade's dramatic rise in crude oil prices to roughly $90 per barrel levels has had a lesser-known, but equally consequential impact on life in the developing world -- a rise in price of cooking oils from palm, soybean and many other types of vegetable oils, The New York Times reported.

The United Nations Food and Agriculture Organization said that exports of 60 internationally-traded foodstuffs increased 37% in 2007, following a 14% rise in 2006. Further, price increases in cooking oils hit the developing world particularly hard, as the bulk of poor families in these countries grow their own food, but buy the oil to cook it with.

In the case of palm oil, The Times reported that rising consumption in China and other emerging markets, along with use of the oil in developed markets as a substitute for chemically-altered trans fats, are two major factors behind its price rise.

Biofuel nexus

However, for other oils the rise in crude oil is playing a considerable role, according to London-based economist Mark Chandler. Chandler, whose economic specialization includes developing world economies, said crude oil's rise has led to a dramatic rise in the use of cooking oils as biofuels.
