According to new research from the University of Minnesota, United States, world grain and soybean yields are not growing fast enough to double harvests by 2050. Output, the researchers said, may fail to meet rising demand unless more land is cleared for farming. According to estimates, agricultural production needs to increase by 60 to 110 percent in order to feed the world in 2050. The research found, based on yield gains in the 20 years through 2008, that global corn production could climb 67 percent through 2050, rice output by 42 percent, wheat by 38 percent, and soybeans by 55 percent. Jon Foley, a study co-author, said, “Clearly, the world faces a looming agricultural crisis, with yield increases insufficient to keep up with projected demands.” The researchers, writing in the journal PLOS ONE, said more efficient use of arable lands, and the use of best management practices could help increase yield growth rates. Changing to more plant-based diets and reducing food waste could also help reduce the expected growth in demand, the authors wrote.
