The lower Murray River (Australia) has been subject to considerable change from human activities, including the conversion of a variable flow system to one with regulated water levels and the conversion of the estuary to a freshwater system. These conditions will face further pressures owing to reduced flows and higher sea levels associated with climate change. Policy decisions to retain present target conditions could be reconsidered to improve habitat conditions for wetlands, native fish and waterbirds. Contrary to many views, this would be permissible under the Ramsar Convention and, by increasing the diversity of conditions, may assist managers to retain functional systems. This paper encourages a new conversation across the broader community to develop pathways to prepare for emerging pressures on the riverine ecosystems, and move into anthropogenic futures for the Lower Murray.

较低的墨累河（澳大利亚）已因人类活动而发生了重大变化，包括将可变流量系统转换为水位已调节的系统，以及将河口转换为淡水系统。由于流量减少和与气候变化有关的海平面上升，这些条件将面临进一步的压力。可以重新考虑保留当前目标条件的政策决定，以改善湿地，本地鱼类和水鸟的栖息地条件。与许多观点相反，《拉姆萨尔公约》允许这样做，并且通过增加条件的多样性，可以帮助管理人员保留职能系统。本文鼓励整个社区之间进行新的对话，以开发出各种途径，为应对河流生态系统面临的新压力做好准备，
