Amount of water used from the aquaculture?water needs to be input as a elementary flow by classifying it into whether consumed water or and used water.In order to input water resources by type, the water resources taken in for aquaculture?water needs to be identified by type and it is generally difficult to identify the type.Accordingly, IDEA creates unit process datasets for use of aquaculture?water, which consist of water withdrawal amount ratio by types of water resources taken in for aquaculture?water, with emphasis on the convenience.
