Joachim von Braun, the director general of the International Food Policy Research Institute (IFPRI) in Washington DC, explained the reasons behind rising food prices to the State Department on May 6. His powerpoint presentation, (sent to me by a colleague) cites three reasons: high demand, high energy costs, and misguided policies, among them growing food for biofuels and–a new one–neglect of agricultural investment. Keith Bradsher and Andrew Martin provide evidence for this last suggestion with an article about how the lack of investment in rice research is hurting the Philippines. Andrew Martin writes in the New York Times about the extraordinary amount of food Americans waste every day–roughly one pound of food per person per day. He cites an estimate from the USDA that recovery of just one-fourth of the waste could feed 20, million people a day. The proverbial food for thought?
