| Zusammenfassung |
| The possible water management of the Plastiras Lake, an artificial reservoir in
central Greece, is examined. The lake and surrounding landscape are
aesthetically degraded when the water level drops, and the requirement of
maintaining a high quality of the scenery constitutes one of the several
conflicting water uses, the other ones being irrigation, water supply, and
power production. This environmental water use, and, to a lesser extent, the
requirement for adequate water quality, results in constraining the annual
release. Thus, the allowed fluctuation of reservoir stage is not defined by
the physical and technical characteristics of the reservoir, but by a
multi-criteria decision, the three criteria being maximising water release,
ensuring adequate water quality, and maintaining a high quality of the natural
landscape. Each of these criteria is analyzed separately. The results are then
put together in a multicriterion tableau, which helps understand the
implications of the possible alternative decisions. Several conflict resolution
methods are overviewed, namely willingness to pay, hedonic prices, and
multi-criteria decision analysis. All these methods attempt to quantify
non-quantifiable qualities, and it is concluded that they don't necessarily
offer any advantage over merely making a choice based on understanding. |
