In order to quantify the impact of agricultural water on local and global environment, the concept of Agricultural Water Footprint (AWF) was proposed based on the theory of water footprint. Firstly, based on the definitions of AWF, this paper compared AWF and Agricultural Virtual Water. Secondly, on the basis of the AWF research, the agricultural types and calculation model were summarized, and the differences and connections between (volumetric water footprint)and (impact-oriented water footprint)were analyzed. Moreover, the paper proposed a conclusion delimiting AWF as environmental impact parameters. Finally, the prospect of application and significance of evaluation of AWF were forecasted. |
