| China has dramatically increased its virtual water import over recent years.
Many studies have focused on the quantity of traded virtual water, but very
few go into analysing geographic distribution and the properties of China's
virtual water trade network. This paper provides a calculation and analysis
of the crop-related virtual water trade network of China based on 27 major
primary crops between 1986 and 2009. The results show that China is a net
importer of virtual water from water-abundant areas of North America and South
America, and a net virtual water exporter to water-stressed areas of Asia,
Africa, and Europe. Virtual water import is far larger than virtual water
export, and in both import and export a small number of trade partners
control the supply chain. Grain crops are the major contributors to virtual
water trade, and among grain crops, soybeans, mostly imported from the US,
Brazil and Argentina, are the most significant. In order to mitigate water
scarcity and secure the food supply, virtual water should actively be
incorporated into national water management strategies. And the sources of
virtual water import need to be further diversified to reduce supply chain
risks and increase resilience. |
