Hydrological restoration of wetlands has become a critical pressing issue in environmental preservation due to climate change. This study seeks to develop a novel methodology to identify which type of water resources available are the most appropriate for restoring a particular wetland, considering a holistic perspective based on the triple bottom line (TBL) assessment, which is a logical framework for identifying and integrating social, environmental, and economic factors into decision-making processes. The elicitation was addressed through a comprehensive holistic index using analytic hierarchy process for ranking TBL dimensions and drivers. This new hybrid technique was applied for elaborating sustainable rules of water allocation to restore the wetlands of the Tablas de Daimiel National Park, located in central Spain. The environmental dimension was analyzed using six drivers: the synergistic use of infrastructures, the water resources location, the wastewater reuse, the energy consumption, the landscape degradation, and the impact on water resources. The social dimension was evaluated measuring three drivers: community acceptance, political acceptance, and market acceptance. And finally, the economic dimension was assessed through the expropriation of land costs, the infrastructure costs, the maintenance costs, and opportunity costs associated. These drivers guarantee traceability and transparency in the elicitation process, becoming a novel allocation framework to support policy makers in wetland conservation. Applying the proposed methodology, Tagus-Segura interbasin water transfer is the best ranked option (83.13%), closely followed by pumping well areas (79.12 and 78.24%) and wastewater recycling plants (74.34 and 68.26%). The unique holistic index proposed is a transparent and traceable decision support tool to address water allocation in wetland restoration.
由于气候变化，湿地的水文恢复已成为环境保护中一个紧迫的关键问题。本研究旨在开发一种新方法，从基于三重底线（TBL）评估的整体视角出发，确定哪种可用水资源最适合恢复特定湿地，TBL评估是一个将社会、环境和经济因素纳入决策过程的逻辑框架。通过使用层次分析法对TBL维度和驱动因素进行排名的综合整体指数来解决这一问题。这种新的混合技术被用于制定可持续的水资源分配规则，以恢复位于西班牙中部的塔布拉斯-德代米耶尔国家公园的湿地。利用六个驱动因素分析环境维度：基础设施的协同利用、水资源位置、废水回用、能源消耗、景观退化以及对水资源的影响。通过衡量三个驱动因素评估社会维度：社区接受度、政治接受度和市场接受度。最后，通过土地征用成本、基础设施成本、维护成本以及相关机会成本评估经济维度。这些驱动因素确保了诱导过程的可追溯性和透明度，成为支持湿地保护政策制定者的新分配框架。应用所提出的方法，塔霍-塞古拉跨流域调水是排名最高的选项（83.13%），紧随其后的是抽水井区域（79.12%和78.24%）以及废水处理厂（74.34%和68.26%）。所提出的独特整体指数是一种透明且可追溯的决策支持工具，用于解决湿地恢复中的水资源分配问题。
