The Okavango River is a major river system in Southwest Africa. It begins in Angola, passes through Namibia and ends in a vast delta in Botswana.

This river system, its ecological and social impact is the subject of a breathtaking new podcast called Guardians of The River.

Guardians of the River won the best narrative non-fiction podcast award at the Tribeca Film Festival -- and after listening to the pilot episode you will understand why. It is produced by the House of Pod, Wild Bird Trust and National Geographic, and available wherever you find podcasts.
