Describe the patterns in grain trade between different world regions over the last 70 years. How does the food crisis of 2006–2008 and food shortages of 2010–2011 relate to these patterns?
What will be an ideal response?
Over the past 70 years countries have shifted from being self-sustaining in food production toward trading foodstuffs with each other. "A number of factors conspired to create the situation where supply was unable to keep up with demand: (1) higher production costs due to the rising cost of petroleum and fertilizer, (2) as we have seen already, the diversion of corn and other commodities to the production of biofuels, (3) a strong demand for higher-quality diets in the emerging economies of Asia, (4) weather-related shortfalls of harvests in key exporting countries, and (5) a background of declining carryover stocks of many commodities."
