Most conventional yield projection models are oblivious to the real world say US researchers 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 […]
