Virtual water flow and water footprint as optimizer of water resource management in the state of Ceará, Brazil

The water exported indirectly by sending products to other countries, or vice versa, is called a virtual water flow and this can be measured through water footprint (WF) calculations, which represent the embedded water needed to manufacture a product. This present study aims to analyze the virtual w...
