Peak Food is a term you may be hearing more of in 2014. The Guardian via Raw Story reports on a new study published in Nature dryly entitled “Distinguishing between yield advances and yield plateaus in historical crop production trends,” but within are some worrying findings:

Industrial agriculture could be hitting fundamental limits in its capacity to produce sufficient crops to feed an expanding global population according to new research published in Nature Communications.
The study by scientists at the University of Nebraska-Lincoln argues that there have been abrupt declines or plateaus in the rate of production of major crops which undermine optimistic projections of constantly increasing crop yields. As much as “31% of total global rice, wheat and maize production” has experienced “yield plateaus or abrupt decreases in yield gain, including rice in eastern Asia and wheat in northwest Europe.”
The declines and plateaus in production have become prevalent despite increasing investment in agriculture, which could mean that maximum potential yields under the industrial model of agribusiness have already occurred.
