China has planted more than 66 billion trees since 1978 under its Great Green Wall project, aimed at halting the spread of the Gobi and Taklamakan deserts. A recent study found that these planted trees are growing faster than natural forests and play a major role in carbon absorption, helping to maintain environmental balance. The government plans to plant an additional 34 billion trees by 2050 as part of the long-term afforestation effort.
Researchers discovered that the planted trees’ leaf area expanded 66 percent faster than that of natural forests, based on satellite data measuring the leaf area index, a key indicator of canopy density and carbon uptake. The study suggests that human-managed forests, often containing fast-growing species such as eucalyptus and poplar, benefit from controlled conditions like pruning and fertilization, which reduce competition for water and nutrients.
However, scientists noted that the rapid growth of planted trees slows after 30 to 40 years, making their carbon absorption benefits temporary. In contrast, natural forests grow more steadily and provide longer-term carbon storage and ecological resilience.
