Including Additional Pollutants into an Integrated Assessment Model for Estimating Nonmarket Benefits from Water Quality
构建了一个综合评估模型,将更多污染物纳入分析,以模拟水质变化对生态系统服务和社会福利的影响,并应用于纳拉甘西特湾,发现污水处理升级和水坝网络每年为周边居民带来数百万美元的价值。
We develop an integrated assessment model for spatially simulating water quality and social welfare from linked ecosystem services that extends prior modeling by incorporating a broader suite of pollutants than conventionally measured factors like phosphorus and nitrogen. Beyond demonstrating the feasibility of such a model, we provide guidance on the impact of omitting or holding constant relevant pollutants and their effect on estimates of water quality and willingness to pay. Applying the model to Narragansett Bay, we find that recent wastewater treatment upgrades and a legacy network of dams are providing millions in annual value to adjacent residents. <i></i>
