From: Physical and virtual nutrient flows in global telecoupled agricultural trade networks

a Physical and virtual sending–receiving effects of nitrogen (N) and phosphorus (P) flow for each kind of product (the order number and agricultural products are shown in Supplementary Information Table S4, the red represents positive values and the blue represents negative values). b Spillover effects of nitrogen (N) and phosphorus (P) flow in 1997, 2003, 2009, and 2016. c (1), (2) Global agricultural trade physical telecoupling effect of nitrogen (N) and phosphorus (P) from 1997 to 2016. c (3), (4) Global agricultural trade virtual telecoupling effect of nitrogen (N) and phosphorus (P) from 1997 to 2016 (all data were provided in Supplementary Data 1).
