Transboundary water pollution coordination decision-making model: an application in Taihu Basin in China

Pollution Load Coordination and Eco-Compensation for Trans-Boundary Water Pollution Control: The Case of the Tri-Border Region of the Yangtze Delta

“…Compared to previous research on trans-boundary pollution control in the Yangtze Delta, which implemented broad management plans covering entire areas of Jiangsu, Zhejiang, and Shanghai, this study introduces a novel method with clearer and refined responsibility identification. Through the delineation of the TECS, the efficacy of transboundary pollution control efforts can be enhanced, and the task volume of trans-boundary pollution control can be reduced by mainly focusing on effective control targets [10,36]. directions and reciprocating ratios in different border regions.…”

“…In summary, the load coordination could be implemented based on the precise load reduction allocation of 13 county-level administrative districts in the TECS. In contrast to setting a flat reduction rate to solve the transboundary pollution conflict in TBYD, as previous research has suggested [10,37], a more precise load reduction scheme for coordination among the different regions has been proposed. This scheme takes into account the diverse spatial distribution of pollution discharge and the complex transportation of pollutants across the entire tri-border area.…”

“…These eco-compensation results reflect the pollution control responsibility of all the regions in the TECS. Compared to the eco-compensation standards previously used in the Yangtze Delta, i.e., COD for CNY 15,000 per ton, NH3-N for CNY 100,000 per ton, and TP for CNY 100,000 per ton, which were established through government consultation and decision making [10,38], a more objective and adapted ecological compensation standard has been derived from the analyzed results of practical pollution treatment costs in the study area.…”

“…Li and Guo [9] developed a dynamic model for transboundary watershed pollution, incorporating emission permits and pollution reduction strategies. Jie Zhang et al [10] introduced a coordination decision-making model designed for the development of emissions reduction schemes and compensation standards within the Taihu Basin. Nan Li et al [11] delved into the dynamics of pollution control behavior among various actors in the Heihe River water transfer project and utilized differential game theories to formulate an incentive coordination strategy.…”

Application Research on Optimal Allocation of Drainage Rights Based on Computer Big Data in Anhui Province of Huai-River Basin

“…Its essence is that first-level allocation is the primary allocation, and second-level allocation is the secondary allocation [4]. Therefore, the project intends to build a two-level diagnostic optimization model of cross-regional and cross-industry collaborative emission reduction by incorporating the maximum benefits of the basin's economy, society and ecology into the overall planning of the basin by restricting the maximum discharge rights quota of the basin [5]. Realize the allocation of trans-regional and transindustrial emission rights quota, realize the fairness and efficiency of trans-regional and trans-industrial emission rights allocation, and maximize the economic benefits of each region and basin.…”
