Traded raw agricultural commodities such as wheat, coffee, sugar, cocoa and rice, and the way those flows move around the global economy, has implications for consumption and production. It also has implications for the price of those commodities.

Price volatility, caused by shocks to supply and demand -- for instance a poor harvest, can at times provoke famine and malnutrition.
