China’s long-term food security and social stability may be threatened unless the world’s largest grain producer invests more to fight the effects of drought, McKinsey & Co. said in a report Nov. 24.

The country’s corn harvest, the world’s second-largest, plunged by 13 percent to a four-year low this year because of drought, a survey of farmers by Geneva-based SGS SA for Bloomberg showed.

The crops affected would include wheat, corn and rice, Zheng Guoguang, head of the China Meteorological Administration, said in an article published on the agency’s Web site Tuesday.

“By 2050, with extreme conditions, South Asia’s grain output could be cut by 30 percent and with the level of global grain stores falling sharply, it would increase the difficulty of boosting imports,” Zheng said. “Trying to make up the difference of lower output by relying on imports doesn’t look very optimistic.”
