Fig. 3: Tripartite network of the virtual water flows (m3) at the company’s scale from Brazilian municipalities to Italy in 2018.
From: International corporations trading Brazilian soy are keystone actors for water stewardship
The map reports the unitary water footprint (uWF) at the company’s scale over the Brazilian territory (layer 1). The links depart from the VW weighted barycenters of production of each company and reach their range of uWFs (m3/ton) and their total exported volume (m3) (layer 2). A unique colour scale is used for each company, the minimum and maximum values of uWF are shown in the first column and their VW export to Italy in the second column of layer 2. Finally, each VW flow is connected to Italy (layer 3). The hierarchies of the companies are aggregated in the treemap, where the empty space accounts for rest of the companies that trade to Italy.
