World Rivers Day
You may not know it, but a global celebration of the world's waterways has taken place on the last Sunday of September every year since 2005. From rallies and special film screenings to community cleanups and riverside get-togethers, this annual event highlights the importance of our rivers and the need to protect them.
In honour of World Rivers Day 2017, here are some of our favourite river recordings from around the world.
