摘要

Urban watersheds in India are currently facing significant hydrological disruptions due to a range of factors, including diminished infiltration capacities, reduced water volumes, altered water chemistry, instability in natural processes, anthropogenic encroachments, and escalating pollution levels. Historically, watersheds were conceptualised as integrated systems for the sustainable management of water resources within a region. However, recent flooding events worldwide underscore the complexities involved in contemporary watershed management practices. Globally, urbanized watersheds are increasingly experiencing stream-flow depletion and deteriorating water quality, which severely compromise the ecological integrity of both in-stream and riparian habitats, as well as the overall water supply. In developing nations, watersheds are essential for providing livelihoods through various products and services. Nonetheless, the unchecked expansion of agriculture and urbanization poses a grave threat to human life and civilization by creating unsustainable demands on land and water resources. By adopting a holistic approach to urban watershed management, cities can reduce the risks associated with urbanization and create more resilient and sustainable water systems. Furthermore, the implementation of nature-based solutions can provide numerous benefits, including biodiversity enhancement, improved water quality, and increased public health and well-being.
