The Algarve province in southern Portugal has been undergoing a rapid growth due to a large increase in tourist demand. The mismanagement of the region’s water resources is leading those growth trends to halt. This paper introduces a model developed to provide a needed rational framework for Algarve water resources management, interfacing a system dynamics model with multiobjective programming formulations. The definition of water supply and demand sectors, on a spatially disaggregated basis, is an essential component of the model, with attempts to provide a tool to evaluate the effects of different strategies controlling water supply and demand upon a set of impact variables. To select an optimal strategy one has to solve a multiobjective programming problem, where the components of the objective function are the impact variables referred above. Solution methods include the analytic hierarchy process and the value display approach. The model written in Z-BASIC was run using a simulation period of 10 years.
