ViWA identifies global hotspots of agricultural water use efficiency
14/10/2019
Virtual Water Values (ViWA) monitors global water use efficiency and develops instruments to efficiently use water resources in agriculture. The project uses an agro-hydrological simulation model and extends a general-equilibrium economic model of agricultural trade with virtual water data. Thus current water use efficiency, crop yields and virtual water flows of traded agricultural goods are simulated. The project further identifies global hot- and coldspots of water use, which serve for an analysis of trade-offs between commercial water use and ecosystem service protection.
