Direct use of water for agriculture in Germany is almost negligible (just 0.3 km³ per year nationwide). At the moment intensive irrigation only takes places in a few regions. In fact, indirect water use has much more of an impact on the water balance: current fertilisation practises pollute the natural water cycle with nutrients. In order to dilute the nutrient contentto a level that is not harmful to humans or the environment, some regions, if they were to observe the German limit, would need more than twice as much water as they have available naturally. The real consequence of the agriculture sector’s grey water footprint is that clean groundwater is becoming scarce at regional level. This film has been produced by the Institute for Ecological Economy Research (IÖW) within the project “Water Flows in Germany” funded by the German Federal Ministry of Education and Research (BMBF).
