The Great Spine of Africa Expedition, led by National Geographic Explorer Steve Boyes, has made groundbreaking discoveries about Africa's water resources and biodiversity. This expedition focuses on the Angolan Highlands, where many of Africa's great rivers originate, providing water security for nearly 500 million people.
During a five-week journey along the Cassai River, a major tributary of the Congo River, the team uncovered that the Munhango River contributes almost twice as much water to the Cassai than previously thought. This revelation highlights the importance of the Angolan Highlands Water Tower, which holds 423 cubic kilometers of water, crucial for sustaining life downstream.
The expedition also documented 143 new species to science, showcasing the rich biodiversity of the region. Boyes emphasized the significance of these findings, stating, 'These are the most detailed river baselines ever undertaken, so in 50 years' time, scientists will be able to make comparisons.'
Despite facing challenges such as navigating landmine-littered areas and dangerous wildlife, the team successfully gathered vital ecological data. Their work is pivotal in informing governments about sustainable water use and conservation efforts in the face of climate change.
Boyes remains optimistic about Africa's resilience, asserting that the continent's water towers can be protected to mitigate the impacts of climate change. This expedition not only highlights the ecological significance of the Angolan Highlands but also reinforces the urgent need for global conservation efforts.
