| Zusammenfassung |
| Integrated Water Resources Management (IWRM) recommends, among other things,
that the management of water resources systems be carried out at the lowest
appropriate level in order to increase the transparency, acceptability and
efficiency of the decision-making process. Empowering water users and
stakeholders transforms the decision-making process by enlarging the number
of point of views that must be considered as well as the set of rules through
which decisions are taken. This paper investigates the impact of different
group decision-making approaches on the operating policies of a water
resource. To achieve this, the water resource allocation problem is
formulated as an optimization problem which seeks to maximize the aggregated
satisfaction of various water users corresponding to different approaches to
collective choice, namely the utilitarian and the egalitarian ones. The
optimal operating policies are then used in simulation and compared. The
concepts are illustrated with a multipurpose reservoir in Chile. The analysis
of simulation results reveals that if this reservoir were to be managed by
its water users, both approaches to collective choice would yield
significantly different operating policies. The paper concludes that the
transfer of management to water users must be carefully implemented if a
reasonable trade-off between equity and efficiency is to be achieved. |
