Food security : framing the real problem

An interesting article in the Economist special report on food security a week or 2 ago. One of the inset boxes contained a short article about food waste at various levels. The developed world waste about 50% of the food produced and the developing world about 20%.

Making agriculture more efficient would be trying to solve the wrong problem. Are vested interests at work to promote the culture of increased production as the only path or is it seen as too hard to change the culture of what and how were eat to cut waste.

I tried to come up with a bias that might explain some of this, but decided I did not know enough about the subject area. Maybe that is a bias in itself?
