| Zusammenfassung |
| This study provides an insight into the impact of China's international
trade of goods and services on its water resources and uses. Virtual water
flows associated with China's international trade are quantified in an
input-output framework. The analysis is scaled down to the sectoral and
provincial levels to trace the origins and destinations of virtual water
flows associated with the international trade. The results show that China
is a net virtual water exporter of 4.8 × 1010 m3 yr−1,
accounting for 2.1% of its renewable water resources and 8.6% of the
total water use. Water scarce regions tend to have higher percentages of
virtual water export relative to their water resources and water uses. In
the water scarce Huang-Huai-Hai region, the net virtual water export
accounts for 8.0% of the region's water resources and 11.3% of its
water uses. For individual sectors, major net virtual water exporters are
those where agriculture provides raw materials in the initial process of the
production chain. The results suggest that China's economic gains from being
a world "manufacture factory" have come at a high cost to its water
resources. |
