Market for irrigation in Germany . The market includes drip irrigation, sprinkler irrigation and surface irrigation. The water supplied to the plants (1m3) and the water evaporated or infiltrated shall be included in the crop production datasets.
The estimated amount of water evaporated and water infiltrated per country, depending on the mix of irrigation technologies (in %) and the technology-specific irrigation efficiency (%). The water which is taken up by the crop is either evaporated (to air) or integrated into the crop.
The water infiltrated is assumed to be released to groundwater (80%) and surface water bodies (20%) based on the ecoinvent documentation. For Germany the values for 1m3 water withdrawn are 0.777 m3 to air, 0.045 m3 to surface water and 0.178 m3 to ground water.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
