Comprehensive assessment of the virtual water trade of Germany with the world is performed and the national water footprint through the trade of crop and livestock products from 1991 to 2016 is assessed. Virtual water flows based on 328 products with more than 200 countries indicate Germany as a net virtual water importer. Average virtual water import was 100.5 Bm3/y, virtual water export was 60.2 Bm3/y and net virtual water import was 40.3 Bm3/y. Trade patterns of virtual water transfer differ for the various commodity types. Trade between Germany and the world implies a global water loss of 5.9 Bm3/y. This study portrays that trade between countries is not only related to the economics but interlinked with the agricultural water use and management practices of the respective nations. Sustainable management of the resources will require a collective consideration of the agricultural, water and economic sectors while developing strategies.
