An integrative case study approach between game theory and Pareto frontier concepts for the transboundary water resources allocations

SummaryIn the context of transboundary issues, this paper introduces a composite water resources allocation approach that integrates both game theory and Pareto frontier concepts over the case of the Euphrates and Tigris Rivers. The proposed approach searches for an acceptable and viable solution set over the Pareto Frontier Surface via game theory based rationality constraints. For this purpose, the used base model is the Euphrates and Tigris River Basin Model, which is a linear programming model maximizing net economic benefits while optimally allocating scarce water resources in the basin. Results indicate that game theory based strategies and associated constraints provide a determinative backbone for an efficient and effective use of generated Pareto Frontier Surfaces. Additionally, estimated marginal values imply that the upstream countries have upper hand positions regarding their geographic and climatic contexts. After all the generation schemes, it appears that Turkey is the critical partner for inclusion into any form of coalition in the Euphrates and Tigris River Basin.

► Upstream countries have upper hand position due to the geographic context.
► Turkey is the critical party to be included into any form of coalition in the basin.
► Game theory provides a reference for an effective use of Pareto Frontier Surfaces.
► Marginal values present tradeoff between country and grand coalition.
