African forests were once a crucial carbon sink. But new research shows that they have started releasing more carbon than they absorb. This change began after 2010 and highlights the urgent need for stronger global efforts to protect forests.

Africa's forests are known for pulling carbon dioxide out of the atmosphere, helping to fight climate change. However, a recent study revealed that these forests have reversed course and are now contributing to emissions. The research shows that between 2007 and 2010, Africa's forests were gaining carbon. But after that, widespread deforestation and degradation pushed the system into decline.

The study used advanced satellite observations and machine learning techniques to analyze more than ten years of forest data. It found that from 2010 to 2017, Africa lost about 106 billion kilograms of forest biomass each year - equivalent to the weight of 106 million cars.

The biggest losses occurred in tropical moist broadleaf forests, especially in the Democratic Republic of Congo, Madagascar, and parts of West Africa. Although some savanna areas saw increases due to shrub growth, these gains were far too small to balance the losses.

Why It Matters

This study highlights the urgent need for stronger global efforts to protect forests. As India's climate is already affected by rising temperatures, it's crucial that we understand the impact of deforestation on our planet and take steps to mitigate its effects.
