Framework for lake rejuvenation to make process ‘technically sound and locally owned’
A new framework for lake rejuvenation has been launched to ensure urban waterbody restoration is both scientifically sound and community-led. The roadmap includes five stages, ranging from diagnosis to long-term monitoring, to address fragmented planning and unclear responsibilities.
Why it matters
This framework addresses the critical need for sustainable urban water management in the face of climate change and rapid urbanization.
Lake rejuvenation, the process of improving the condition and functioning of a lake so that it can achieve target functions such as flood mitigation, recharge, storage for indirect potable reuse, and ecological or social services, often see interventions focused on outputs, such as installation of flood control infrastructure in a lake, rather than prioritising outcomes, like the flood control function performed by the waterbody.
A new Framework for Lake Rejuvenation aims to fix this with a five-stage, structured, science-backed, and community-informed roadmap for rejuvenating urban and peri-urban lakes: diagnosis and visioning, design, implementation, operation and maintenance, and monitoring and evaluation.
