Embodied agricultural water use in China from 1997 to 2010.

摘要: Abstract Water is an important element in agricultural production. The recent population growth, rapid urbanization, and fast industrialization present increasing challenges for China's water use. Embodied has been promoted as a substantial indicator the assessment of consumption induced by human activities. However, few studies have investigated dynamic change embodied use time-series data. findings such may facilitate development comprehensive sustainable water-usage strategies. Thus, this study quantifies trade, well production- consumption-based footprints China using input–output model during 1997–2010. According to results, average intensity shows declining trend from 43.33 m3/thousand Yuan 1997 32.66 m3/thousand 2010. primary industry larger than those secondary tertiary industries. always net exporter water. At industrial level, importer because food demand China, consistently exporter, maintained trade balance. uses demonstrate similar changing trends: both decrease 2007 then significantly increase consumed downward trend, whereas industries opposite trend. Therefore, addition improvement efficiency, adjustments structure are highly instrumental conservation local resources.
