Fig. 17.2. Values of the perfonnance indicator IP (see Eq. 17.1 for definition); irrigation
systems: Torre de Abraham (sprinklers) and Pefiarroya (furrows) both in Spain; irrigation
seasons: 1989, 1991 and 1996 (Boss and Jacobs, 1997, personal communication)
In practice, most practical approaches are case-specific and cannot be transferred
to different situations without taking into account differences in characteristics of
farming systems such as the cropping pattern or climatic factors. In the next pages
several examples of applications are briefly described to direct readers towards
literature relevant to their requirements.
