Africa’s forests, once a critical carbon sink absorbing more greenhouse gases than they emitted, have flipped to becoming a net carbon source after 2010, according to a new study. The reversal, driven by extensive deforestation in tropical regions, represents a significant blow to global efforts to combat climate change. Scientists warn that the trend underscores the urgent need to protect and restore forests across the continent.
The study, published by a team of international researchers, found that biomass losses from deforestation in Africa’s tropical forests far outweighed gains from regrowth in other areas. Analysts attribute the deforestation to agricultural expansion, logging, and infrastructure development. “This shift from sink to source is alarming,” said a source close to the research team. “It highlights the fragility of ecosystems under pressure from human activity.”
Africa’s forests play a vital role in the global carbon cycle, storing vast amounts of carbon dioxide. Their loss not only accelerates climate change but also threatens biodiversity and the livelihoods of millions who depend on forest resources. Officials from environmental organizations have called for immediate policy interventions, including stricter enforcement of anti-deforestation laws and increased funding for conservation projects.
Looking ahead, experts warn that failure to address the issue could undermine international climate goals, such as those outlined in the Paris Agreement. “Protecting forests must become a global priority,” said an analyst. “Without decisive action, we risk losing one of our most effective tools for mitigating climate change.”
