Alain de Janvry, UC Berkeley, speaks about the identification of the vulnerable in developing countries.  He focuses on the rural poor as the worst off in a food price crisis because they are net buyers of food and cannot mobilize to the extent that urban populations can.  De Janvry also pinpoints on the reduced spending by governments and donors for agricultural research and development in the last 25 years and states that we must redevelop the pipeline for using agriculture for development. 22 min.
