What's New

October 16 is World Food Day.

About one in eight people worldwide suffered from chronic hunger during the past two years, according to the United Nations. Though daunting, that ratio is an improvement over previous years. In fact, the 2013 Global Hunger Index report released Monday shows that global hunger levels have declined by nearly 35 percent since 1990.

The great hope that rose from the Arab awakening is being continually tested—not only by ongoing political unrest, but also by lesser known forces: volatile food prices and supplies, and grinding poverty. Translating hope to better lives rests on effective policy—and effective policy rests on access to adequate and accurate information, also in scarce supply in the region. For instance, only around half of the region’s countries make poverty figures publicly available, and the frequency and accuracy of those figures varies widely.

In recent days, the price for soft wheat has increased, as has its volatility. This increase in volatility has likely stemmed from reports that cold weather in Europe may damage crops, a fear that may in fact have been overstated. Reports from Russia about a potential new levy on wheat exports starting in April 2012 may have also played a part in this week's increased volatility.

Asymmetry of information is a major obstacle to increasing global food security. Having access to reliable food price and market information is critical for policymakers, food policy experts, and researchers to be able to respond quickly to dynamic developments in the global food system.

The price of agricultural commodities is determined by many different variables, including production quantities, currency rates, weather events, political or social turmoil, and the price of inputs needed to produce those commodities. Throughout the world, fertilizers are a major agricultural input, and thus a major factor in the price of agricultural commodities.
