ABSTRACT

Over the eight years since the onset of the great food crisis of 2007-09, when high food prices forced over 200 million additional people into the ranks of the hungry, global humanity crossed a new threshold with well over a billion people in hunger. This realization has forced new and important considerations about our capacity to feed a world population expected to be about 9.6 billion by 2050 even as very serious climate-change effects threaten to decrease the current productivity of our agricultural system.
