Germany is a country rich in water but water availability and water use have an uneven regional distribution. This leads to regional scarcities which may significantly aggravate due to the climate change. On the poster, the natural, artificial and virtual water flows in Germany are, for the first time, prepared innovatively and directly related to each other. The front side of the poster shows a map of Germany that visualizes the water flows and the regional water balance. The back side provides additional information, maps and graphics on availability of water in Germany, groundwater contamination, the impact of climate change and the use of virtual water.
