Africa's Albertine Rift

As the global population soars toward nine billion by 2045, this corner of Africa shows what's at stake in the decades ahead. The Rift is rich in rainfall, deep lakes, volcanic soil, and biodiversity. It is also one of the most densely populated places on Earth. A desperate competition for land and resources—and between people and wildlife—has erupted here with unspeakable violence. How can the conflict be stopped? Will there be any room left for the wild?
