Feed-associated water consumption can be regarded as all the
human-induced water use during the life cycle of the feed, as the
CEENE method only accounts for human-induced water use, i.e.
surface and groundwater use. Human-inducedwater use is defined
as water which is extracted from the environment in a forced way
(e.g. water pumped from a river). Accordingly, the CEENE method
does not account for rainfall, which means that rainfall is not
included in the water use of agricultural production processes, as is
the case in the ecoinvent datasets. Just as with solar radiation,
rainfall is a non-forced environmental input, which is only accessible
through land occupation. Therefore these inputs are better
considered in the context of the land occupation impact category.
This reasoning is also shared by Ridoutt and Pfister (2010).
