Chinese agriculture currently faces major environmental challenges. China’s applications of fertilizers and pesticides are among the highest in the world, which in turn has negative impacts on human health and environment.

Meanwhile, food safety risks €“ exemplified by a series of well-publicized incidents such as the 2008 milk-melamine scandal are a source of great public anxiety.
