Abstract

Water footprint (WF) can help understanding of how to grow more food with less water. The aim of this paper is to distinguish the factors influencing the paddy rice water footprint, by using path analysis of the WF, its composition and distribution over 30 provinces, municipalities and autonomous regions (hereafter, provinces) in China during 1996–2015. The results show that the annual national WF was approximately 190.74 G m³, including 55.41 % green, 22.65 % blue and 21.94 % grey water respectively. WF basically remained stable over time. WF of the northeast increased from 16.70 G m³ to 39.19 G m³ during the observed period. WF for per unit paddy rice product (WFP) was 995.5 m³/t in the la..
