Only one third of the world's rivers have natural flows

Currently, only one-third of the world's 246 largest rivers have natural flows, according to research by World Wildlife Fund and other organizations. The number of remaining rivers has been affected by people such as shaping the flow, building a dam or even blocking the flow.

WWF and McGill scientists tracked more than 12 million kilometers of rivers around the world to get this result, and most unaffected rivers are in remote areas like the Arctic. In the Amazon basin or the Congo basin, the rest are more or less affected by people or the consequences of climate change.

In this, it is clear that the human element accounts for a very large part because it is not clear where people have clear plans to keep the flow naturally the most. There are many places where dams have been placed to store water or to irrigate hydroelectricity, seriously reducing biodiversity as well as adversely affecting agriculture and fisheries. According to the figures in the current report, the whole world has more than 60,000 large dams, if including small dams, this figure must be up to several hundred thousand dams that are already going to be built and cutting rivers. all around the world.

WWF has now released a detailed set of river definitions with the expectation that countries can take it for reference, to study how to conserve rivers flowing through their own countries and to conserve them. biodiversity is disappearing.
