Water is the most valuable natural resource in Bangladesh. Water is the lifeline for agriculture, fisheries, inland navigation, industries, and aquatic ecosystems. Bangladesh’s dependence for flow of water on upper riparian countries is the root cause of vulnerability of the precious resource. Co-riparian countries within the Ganges–Brahmaputra–Meghna basin need to address the future of water resources management in the context of climate change. Water is one of the most valuable and essential resources that humans need to sustain their livelihood. It is needless to say that without enough good water our survival will be threatened. Water quality in rivers and streams is controlled by land-use practices in watersheds. The government of Bangladesh published the Water Act 2013, which is based on the National Water Policy, and designed for integrated development, management, extraction, distribution, usage, protection, and conservation of water resources in Bangladesh.
