Methods
Integrative approach. In this paper, an integrative approach was used to consider food production
as part of an environmental system (soil, air, water, biodiversity) and not independent from it. The
major viewpoints were discussed at the “Joint UK-China Summit on Food Production and
Environmental Sustainability” held in Beijing on 5-6 March 2014, with 40 leading scientists,
administrators and business people from UK and China participated. Valuable comments were also
provided by the representatives from the Ministry of Agriculture, Ministry of Environmental
Protection, State Council Development Research Centre and other relevant ministries and
organizations.
Statistical analyses were performed with SPSS Statistics V20.0 (SPSS Inc. Quarry Bay, HK).
Multiple regressions were used to determine the increase in anthropogenic reactive nitrogen emissions
in China since 1980. Spatial distributions of water resources, water pollution and grain yield were
performed with the Arcmap module in ArcGIS V10.0 software (ESRI, Redland, CA).Social network
analysis was made of the relationships among the relevant governing bodies for ensuring food
security.
Dataset. Data were collected from the following sources: (1) a number of national and provincial
statistical databases, including “China Statistical Yearbook,” “China Water Resources Bulletin”,
“China Agricultural Statistical Yearbook,” and “China Environmental Status Bulletin” ; (2) national
or provincial environmental quality standards or survey reports such as Environmental Quality
Standards for Surface Water, and Environmental Quality Report; and (3) the existing research results
and methodologies described in respective tables or figures.

Figure S3. The increase in China’s real GDP since 1950 and the predicted continued increase
to 2020.
The growth was steady until 1980 and increased rapidly to 2010 with a predicted further
doubling by 2020. Both GDP and per capita GDP are normalized to 100 in 1978.
Sources: data before 2010 from NSBC (2009, 2013) and data thereafter are estimated by authors.

Figure S5. Water availability index for China. Stressed areas (orange and yellow) are mainly
under pressure from agricultural use.
Note: Here water security index is scored between 0 and 100 according to water demand satisfaction
ratio for different water uses. A score higher than 90 means very secure, 80-89.9 means secure, 70-
79.9 means relatively secure, 60-69.9 means relatively not secure, while score lower than 60 very
unsecure.
