Africa’s tropical forests, once vital carbon sinks, have become net emitters of carbon dioxide since 2010 due to rampant deforestation and ecosystem degradation, according to new research. The study reveals that biomass losses in heavily logged regions now exceed carbon sequestration from forest regrowth elsewhere, marking a dangerous tipping point for global climate efforts.
The findings, published in a peer-reviewed journal and summarized by ScienceDaily, show that Central Africa’s Congo Basin—the world’s second-largest rainforest—has experienced particularly severe declines. Analysts attribute the shift to industrial logging, agricultural expansion, and infrastructure development accelerating after 2010.
‘This reversal undermines one of Earth’s critical climate buffers,’ said a climate scientist familiar with the research who requested anonymity ahead of formal publication. ‘At current rates, Africa could contribute more to atmospheric CO2 from forest loss than from fossil fuels within 15 years.’
Historical data indicates African forests absorbed approximately 0.6 petagrams of carbon annually pre-2010. Satellite imagery and ground surveys now show emissions surpassing absorption by 10-15%, with annual biomass losses equivalent to Denmark’s total carbon footprint.
Environmental officials warn this trend could jeopardize international agreements like the Paris Accord. ‘Without immediate intervention, we risk triggering feedback loops where forest loss begets further climate-driven degradation,’ noted an unnamed UNEP representative.
Experts suggest strengthening conservation policies and alternative livelihoods for forest communities as potential solutions. The study’s authors urge incorporating these findings into COP27 follow-up negotiations, with implications for carbon credit systems and climate financing.
