Environmental flow is the amount of water needed in a watercourse to maintain healthy ecosystems. The term is used in the context of rivers which have been dammed, with most or all of the flow trapped by the dam — the failure to provide an environmental flow can have serious ecological consequences.
According to the Global Environmental Flows Network, only a few countries, such as Australia, South Africa, and the UK have integrated the concept into water management.[1]
In 2007, the Brisbane Declaration on Environmental Flows was endorsed by more than 800 delegates from 57 countries. The declaration announce an official pledge to work together to protect and restore the world’s rivers and lakes
