Congo Basin

Spanning across Cameroon, the Central African Republic, the Democratic Republic of the Congo, the Republic of Congo, Equatorial Guinea, and Gabon, the Congo Basin covers a vast area of tropical forest, wetlands, and rivers. It is often referred to as the lungs of Africa and is home to an estimated 10,000 plant species, of which approximately 30 percent are unique to the region. The basin also supports diverse wildlife, including at least 400 mammal species, 1,000 bird species, and 700 fish species, featuring iconic animals such as forest elephants, gorillas, chimpanzees, and okapis. The region is a globally significant carbon reservoir. Scientific estimates indicate that the basin's forests and peatlands hold massive carbon stocks, with one recent study citing approximately 36 gigatons of carbon in forests and 29 gigatons in peatlands. While estimates of the basin's annual carbon uptake vary—with some remote sensing data suggesting 0.26 gigatons of carbon per year and ground-based studies measuring between 0.28 and 0.50 gigatons per year—the basin is widely recognized as a crucial net carbon sink that helps mitigate global climate change. Despite its ecological importance, the Congo Basin faces significant threats. The primary drivers of deforestation and forest degradation include small-scale subsistence agriculture, the expansion of industrial logging, mining, and the development of infrastructure such as roads. These activities not only lead to direct forest loss but also increase access for commercial hunting, which has severely impacted populations of large mammals like forest elephants. Looking ahead, the region faces mounting pressure from a growing human population and the demand for economic development. Experts warn that industrial-scale agriculture, such as palm oil and rubber plantations, poses a major future threat. Furthermore, there are concerns that if deforestation and degradation continue at current rates, the basin could reach a tipping point where it may no longer be able to support its unique rainforest ecosystems and the essential services they provide.
