Drought 'poses threat' to grain security

Increasing frequency and severity hit supply: experts

BEIJING - The frequency and severity of droughts have increased over the past decade, causing heavy crop losses and posing a potentially grave threat to grain security, leading agriculture experts warn.

"Catastrophic drought occurred once every five years in the 1950s and once every two years in the 1990s. But in the past 10 years it's been almost every year," Li Maosong, director of the Agricultural Information Office at the Chinese Academy of Agricultural Sciences (CAAS), told China Daily.
