The past decade has seen increased international recognition of the importance of the services provided by natural ecosystems. It is unclear however whether such international awareness will lead to improved environmental management in many regions. We explore this issue by examining the specific case of fish migration and dams on the Mekong river. We determine that dams on the Mekong mainstem and major tributaries will have a major impact on the basin's fisheries and the people who depend upon them for food and income. We find no evidence that current moves towards dam construction will stop, and consider two scenarios for the future of the fisheries and other ecosystems of the basin. We conclude that major investment is required in innovative technology to reduce the loss of ecosystem services, and alternative livelihood strategies to cope with the losses that do occur.
在过去的十年中，人们越来越认识到自然生态系统所提供的服务的重要性。然而，这种国际意识是否会导致许多地区的环境管理得到改善，尚不清楚。我们通过考察湄公河上鱼类洄游和水坝这一具体案例来探讨这个问题。我们的研究结果表明，湄公河干流和主要支流上的大坝将对该流域的渔业以及依赖渔业获取食物和收入的人们产生重大影响。我们没有发现任何证据表明目前的大坝建设行动将会停止，并对该流域渔业和其他生态系统的未来设想了两种情景。我们的结论是，需要在创新技术方面进行重大投资，以减少生态系统服务的损失，并制定替代生计战略，以应对不可避免的损失。
