Virtual Water Trade
A precise tool.
What is the Virtual Water Trade & How does it work?
Virtual water trade quantifies the hidden water embedded in imported goods, highlighting how regions depend on external water resources. By calculating the product of import volumes and commodity-specific water footprints, policymakers can assess the sustainability of trade patterns and identify opportunities for water‑saving strategies. Understanding virtual water flows also supports international negotiations, as nations can balance water scarcity with economic development through informed trade decisions.
