“…This paper furthers the study of Xu et al [15], and the main innovation is to quantify the impact of uncertainty induced by climate change on the decision behaviors of conflict-resolution methods. The paper is organized as follows: Section 2 introduces the methodology, including the prediction of reservoir inflows under different climate scenarios, the establishment of the multi-objective optimization model, and the resolution of the water conflict between hydropower generation and environmental protection.…”

“…Therefore, in this paper, environmental flow (EF) for the middle and lower reaches of the Yangtze River had to be determined. Based on the basic flow method [29], Xu et al proposed three EF patterns for the study area: basic flow (BF), maintenance basic flow (MBF), and appropriate environmental flow (AEF) [15]. Different from the former two patterns, AEF was determined by considering the reproduction of aquatic organisms living in the study area, which is more environmentally friendly to the ecology of the river.…”

“…Alizadeh et al found that four social choice methods and two fallback bargaining methods could effectively resolve conflicts that arose from groundwater management, which resulted in reduced groundwater exploitation and an increased water level [13]. Xu et al (2019) investigated the decision-tendencies of fuzzy social choice methods, which are extensions of social choice methods and consider uncertainty in the decision behaviors of stakeholders [14], and game-theoretical bargaining methods for conflict resolution in multi-objective reservoir operation, and indicated that the decisions of game-theoretical bargaining methods were more stable than those of fuzzy social choice methods [15]. Although the decision characteristics of social choice methods and game-theoretical bargaining methods were analyzed in those studies, they assumed the available quantity of water resources based on a single predetermined climate scenario, without considering various climate change scenarios.…”

To balance the water demands of different departments and produce a win–win result for reservoir operation, a series of conflict-resolution methods have been developed to define the socio-optimal operation strategy for specific conflict problems. However, given the inherent uncertainty of reservoir operation brought by climate change, the compromised strategies selected by conflict-resolution methods can vary. Therefore, quantifying the impacts of climate change on the decision characteristics of conflict-resolution methods can help to address questions about whether conflict-resolution decisions are sustainable given unforeseen changes. In this study, the Yangtze River is regarded as study area. As a world-class hydropower project located on the midstream of Yangtze River, Three Gorges Hydroelectric Power Station can transfer plenty of water energy into electricity. To alleviate the ecological water shortage caused by hydropower operation, sustainable and balanced operation strategies considering the water demands of two departments needs to be studied. In the context of hydropower-environmental conflict-resolution management, the decision behaviors of two fuzzy social choice methods and four game-theoretical bargaining methods under 25 kinds of future climate scenarios are analyzed. Comparing the strategy selection results of different methods for a future period (2021–2082) shows that in all proposed climate scenarios, the decisions of the Nash bargaining method, alternating offer method, and unanimity fallback bargaining method in game-theoretical bargaining methods are more stable than other studied methods, which means that climate change affects the decision behaviors of these three methods slightly. In addition, balanced strategies selected by these three methods could formulate adaptable reservoir operation policies that would satisfy the interests of hydropower and environmental stakeholders equally, and avoid a very low satisfaction level of individual stakeholder and whole stakeholders in the water-conflict year. Therefore, against the background of an increasing demand for environmental protection, these three methods can provide socio-optimal strategies considering social and economic benefits for water resource management.

“…Bargaining techniques can help create an arrangement to reach broad agreements among stakeholders on specific policies through negotiation, considering the shared resources' utilities and limitations (Madani, 2010). Thus, these techniques have been used in many water resources management studies to analyze stakeholders' potential behaviors (Carraro & Sgobbi, 2008;Mahjouri & Bizhani-manzar, 2013;Xu et al, 2019).…”

Bottom-up capping (BUC) policy under bargaining techniques for inter-sectoral groundwater trading: a case study from Iran

2021

Cap-and-trade (C&T) policy has led to environmental benefits in some groundwater markets by restricting and economically reallocating water permits. However, top-down approaches for capping permits may face resistance of every affected stakeholder. This paper presents an efficient policy framework to improve the implementation of C&T policies in a real shared aquifer in Iran. To this end, groundwater permits for water-selling farms are capped through a bottom-up capping (BUC) policy. A policy analysis that employs static and dynamic bargaining techniques incorporates farms' utilities. Results reveal that the bargaining techniques propose more acceptable capping strategies than the top-down approach. The BUC policy analysis introduces the proposed strategy by dynamic bargaining as the tradable groundwater permits. The effects of irrigation water sales to the industry sector, evaluated using a cooperative game-based optimization model, show that with the fair reallocation of water trading benefits, the current net benefits of agriculture and industry sectors increase by 55 and 27%, respectively. Furthermore, farms reduce their groundwater withdrawals by 35% compared with the current mode. Therefore, the BUC policy for inter-sectoral groundwater trading under dynamic bargaining can lead to the sustainable use of limited groundwater resources by facilitating the capping strategies and improving the water permits productivity.
