Virtual water content (VWC, L/kg) of different food products. Subplots (a) and (b) show the blue and green VWC (VWCbl and VWCgr) of food products by subregion (upstream, midstream, downstream, and basin-wide average), whereas subplots (c) and (d) present the corresponding values at the provincial level. Subregions are grouped according to their location within the YRB. Detailed data are available in Tables T2–T3, and a list of subregional administrative divisions is provided in Table T4, SI.
