The study described in this article incorporates stakeholders' views on aquatic invasion processes and combines expert analysis with information from field work into an evaluation exercise. Management scenarios are designed based on available technical data and stakeholders' perceptions. These scenarios are evaluated using the Social Multi-Criteria Evaluation framework employing the NAIADE model. Two evaluations are carried out, technical and social. Social acceptance of different management scenarios, distribution of costs and benefits, and attribution of responsibility are discussed. The case study was carried out on Lake Izabal, a body of water connected to the Caribbean Sea in Northeastern Guatemala. In 2000, local fishermen reported the presence of an alien species in the lake, the macrophyte Hydrilla verticillata. Two years later, this alien species was established around the entire lakeshore, damaging the ecosystem, endangering native species and the subsistence of local inhabitants through impacts on transportation, fishing practices, and tourism.
本文所描述的研究纳入了利益相关者对水生入侵过程的看法，并将专家分析与实地工作信息结合起来进行评估。根据现有技术数据和利益相关者的看法设计管理方案。使用社会多标准评估框架和 NAIADE 模型对这些方案进行评估。进行了两次评估，即技术评估和社会评估。讨论了不同管理方案的社会接受度、成本和收益的分配以及责任的归属。案例研究在危地马拉东北部与加勒比海相连的伊萨瓦尔湖进行。2000 年，当地渔民报告说湖中出现了一种外来物种，即水生植物水蕴草。两年后，这种外来物种在整个湖岸建立起来，破坏了生态系统，通过对交通、捕鱼活动和旅游业的影响，危及本地物种和当地居民的生计。
