The majestic River Ganga is a sacred environment which nurtures more than 650 million people in her large watershed. The Ganga has proved resilient despite the multiple, enormous, environmental stressors placed on her. The Laurentian Great Lakes have also faced severe environmental degradation and the lessons learned there over the past 50 years can provide guidance for the remediation and restoration of the Ganga. One of the more important lessons is defining Beneficial Use Impairments to focus remediation efforts in degraded Areas of Concern. This paper provides a case study of one such impairment, Eutrophication or Undesirable Algae, and shows how it can be applied as part of a broader Ecosystem Approach towards the identification and selection of Ganga Areas of Concern. The 10 proposed Ganga Areas of Concern are intended to provide guidance to all stakeholders on how and where to focus remediation efforts on the Ganga, and similar ecosystems throughout the world.

Laurentian Great Lakes“生态系统方法”在印度恒河修复和恢复中的应用†

雄伟的恒河是一个神圣的环境，在她的大流域养育了超过 6.5 亿人。尽管给她施加了多重、巨大的环境压力，恒河已被证明具有韧性。劳伦森五大湖也面临着严重的环境退化，过去 50 年的经验教训可以为恒河的整治和恢复提供指导。更重要的经验之一是定义有益使用损害，以将修复工作集中在受关注的退化地区。本文提供了一个此类损害（富营养化或不良藻类）的案例研究，并展示了如何将其作为更广泛的生态系统方法的一部分来识别和选择恒河关注区域。
