World grain and soybean yields are not growing fast enough to double harvests by 2050, meaning output may fail to meet rising demand without clearing more land for farming, according to a University of Minnesota study.
Based on yield gains in the 20 years through 2008, global corn production may climb 67 percent through 2050, while rice output would rise 42 percent, wheat 38 percent and soybeans 55 percent, researchers led by Deepak Ray at the university wrote in a study published via online journal Plos One.
