Will we be able to feed 9.5 billion people?

The Aspen Ideas Festival is over. You nor I went to that one means that apparently we did not have ideas that anybody wanted to listen to, or we did not have the money to listen to those with ideas! Oh well ....

James Fallows was one of those that the attendees wanted to listen to, and has blogged about a session he moderated; it was on "Feeding the World's Billions." Fallows writes:
Sample alarming fact: if the world population eventually tops out at 9.5 billion, 50% more than now, total food production will probably have to grow by 200%, as people eat higher up the food chain and demand more and more meat. The challenge, as several panelists put it, was to produce three times as much food on no more than the current amount of agricultural land. (About why it won't just work to cut down all remaining forests to grow food, see here.)

Sample specific solution-possibilities, or at least interesting facts: Average yields in U.S. farms are roughly three times as high as the overall average for Mexico, India, and Brazil. If those countries got to even two-thirds of the US level, it would make a huge difference in closing the "grain gap." Also: a huge share of the world's food output is wasted -- in the developing world because it rots and spoils before it can get to market, and in the US to a significant degree because of restaurant waste. Thus easy opportunities for gain.
I am sure the neo-Malthusians will be all over this one in no time at all ....
