If China is to achieve its target of 95% grain self-sufficiency by 2030 it will need to restrict the conversion of arable land to other uses say researchers from McGill. This may prove challenging in a country with a population of almost 1.4 billion, but with just under 13% of arable land, close to half of which is suffering from soil degradation. After analyzing the potential impacts of various current trade-related food policies, the researchers have arrived at the conclusion that the current Red Line arable land protection policy is insufficient to reach the government’s desired goal.
