Every six seconds a child on this planet dies of hunger.

We’ve had industrial revolutions in the west and more recently in China and South Asia; budding revolutions in “superjumbo” aircraft and plug-in electric cars; and Seinfeld episodes that can be downloaded onto cellphones worldwide.

Yet we remain trapped in some previous century in that most basic of necessities; keeping the world population fed. Remarkably, the facts today point to yet another global food shortage just a few years after the food crisis of 2007-08, which ended only when the Great Recession curbed a debilitating upward spiral in prices of basic staples like rice, corn and wheat worldwide. As the world economy recovers, the prospect of another global food crisis looms large.

The determining factors in famine are mostly man-made. They include civil war and political instability in many, if not most undernourished regions. Protectionism in affluent nations that removes the incentive for developing-world farmers to enhance crop yields in the hope of earning export revenue.
