Evaluation of water footprint for Guangdong province in an interregional input-output framework
摘要
Abstract
Under the impacts of human activities and global climate change, it experiences increasingly serious water resources shortage in Guangdong Province. Water footprint links water use and human consumption, serving as a new way for alleviating water crisis. By using Multi-Regional Input-Output method and socio-economic statistical data, water footprint of Guangdong Province, China in 2007 is evaluated. The results show that, (1) the total water footprint of Guangdong was 316.4×108 m3 in 2007, 35.9%of which was external water footprint and the other was local water footprint; (2) comparing among the three major industries, consumer demand of the primary industry was the smallest whereas it showed the largest water footprint; in contrast, the tertiary industry had the largest consumer demand but relatively low water footprint, and the external water footprint of Guangdong was mainly provided through the primary industry; (3) the external water footprint of Guangdong was mainly provided by Hunan, Guangxi, Hubei and Guizhou province; the amount of external water footprints decreased as distance between the providers and Guangdong increases;(4) the primary industry consumed most water resources directly with its total water consumption coefficient being the highest, while the other sectors consumed water indirectly. Based on these results, suggestions such as adjusting industrial structure and increasing water consumption efficiency, were proposed to improve water resources management in Guangdong.关键词
