The balance between wilderness areas and the species that depend on them are fragile and are being threatened. Environment Editor for The Times, Adam Vaughan joins conservationist and National Geographic Explorer Steve Boyes in Zimbabwe to investigate why Africa’s greatest water sources - the rivers that run through the heart of the continent - are crucial to a prosperous future environment in Africa and beyond. 

Through its Perpetual Planet Initiative, Rolex supports the Great Spine of Africa expeditions that traverse and document thousands of kilometres of rivers never scientifically documented before.

This is Planet Hope, a new podcast from The Times in partnership with Rolex and its Perpetual Planet Initiative.
