China is an important country within the global food web，producing one quarter of the world’s grain and feeding one fifth of the world’s population on only ten percent of the world’s arable land[33].Agricultural production is subject to an interplay of pressures，including demographic changes from sustained population growth，rural-urban migration and changing consumer preferences.These factors are combined with pressures on natural resources（including land and water）that have been negatively impacted by the inefficient use of，and over reliance upon，agricultural fertilisers to maintain yields（with use increasing 4%annually，amounting to one third of global fertilizer usage）[32].China’s response to its social and environmental challenges is affected by its social and agricultural landscape，which is characterized by a preponderance of small scale‘family farms’that account for 99.2%of all farms in China（Table 2），which are relatively inefficient in terms of food production[34].These factors combine to threaten national food security，and pose a challenge to adoption of potential solutions[10–12，35].
