Integrated water management using feasible goals method and interactive decision maps: the case of Odivelas irrigation

Abstract

In Mediterranean areas water scarcity is a real problem and stakeholders have conflicting visions and interests. This paper aims to determine feasible and efficient combinations of stakeholder goals using an integrated water management approach. A framework based on the feasible goals method/interactive decision maps (FGM/IDM) technique to approximate all Pareto optimal solutions of a linear multi-criteria model was developed. The model was applied to the Odivelas irrigated area in southern Portugal and a participative decision making was obtained considering multiple stakeholders goals that are in conflict.
