Freshwater ecosystems deliver various ecosystem services providing essential goods and services, on which humans depend. These include vital provision of water for domestic, agricultural and industrial use. Lake Pamvotis, a heavily modified urban lake is providing multiple services but at the same time is under multiple pressures. Setting as target the achievement of the Water Framework Directive (WFD) "Good Ecological Status or Potential" goal and acknowledging the revised River Basin Management Plan's Program of Measures, a set of six alternatives is suggested. For the preferable alternatives' selection, six criteria were adopted whose relations are given through a Driving Forces-Pressure-State-Impact-Responses (DPSIR) conceptual model. Qualitative judgments based on expert opinion are selected to describe the scores of the criteria which are finally evaluated as fuzzy numbers. A hybrid method which incorporates the outranking relation and the right of veto of the ELECTRE III method, and finally the net flow of the PROMETHEE method is developed. The proposed method is based on fuzzy sets and logic in order, firstly to interpret both the monocriterion comparison and the aggregation among the criteria and secondly to enable the evaluation of the criteria with fuzzy scores. The results prioritized the increase of the water quality for the improvement of water related ecosystem services among the other alternatives in all tests. The proposed method is suitable for environmental problems where the evaluation of the scores is not crisp and furthermore, commensurate alternatives are demanded.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
