Geisler and Currens note, however, that "Peak Farmland, though newly named, is a long-standing issue" that has been debated by scholars for decades.[1] The issue deals with two opposing views: one that predicts that more and more farmland will be needed to sustain the growing world population, and the other (the peak farmland view) that progress in agricultural techniques, measured in steadily increasing crop yields from a set amount of farmland, will result in a decrease in the amount of farmland needed to feed the world's population, eventually leading to a decrease in the world's acreage of farmland.[5][3]
