A multi-objective analysis is presented considering the consumption of fresh water, the greenhouse gas emissions, and the cost of the integrated system as objective functions.
The results show that it is possible to satisfy the water, energy, and food needs in isolated communities accounting for integrated processes. Besides, it is possible to obtain trade-off solutions considering contradicting objectives. To trade-off the proposed objectives, it is presented a multistakeholder approach which is capable to find the compromise solution which is the point where the objectives are minimized simultaneously. The results show that the compromise solution is very close of the Utopian Point, which indicates that is possible to obtain a solution that satisfies almost entirely the minimum of the objectives.
