Planting Trees To Combat Climate Change
China is on track to meet its 2020 target for expanding the nation’s forests to cover 23 percent of its landmass to combat climate change and soil erosion, the State Forestry Administration (SFA) said on Tuesday. But some observers are critical of the massive reforestation, saying China is focusing on plantation forestry and ignoring the restoration of natural forests, which are still being lost.
Since 2008, China has planted 13 million hectares (130,000 square kms) of new forests, roughly the size of Montenegro, taking total forest coverage to 208 million hectares (two million sq kms) or just over 21 percent of its landmass.
“We have completed 60 percent of our task to meet the target for forest coverage and aim at 23 percent (of the landmass) by 2020,” Zhao Shucong, the director of the SFA, told reporters in Beijing.
China launched its reforestation program in 1998, after devastating flooding of the Yangtze river was blamed on the loss of trees, which previously had acted as flood barriers. Large-scale deforestation in northern China has contributed to loss of topsoil, causing huge storms that sometimes carry sand and dust as far as eastern Canada.
Trees Can Save Water
By regrowing its forests quickly, they now help conserve 581 billion cubic meters of water each year, while storing 8.4 billion tons of carbon dioxide equivalent that otherwise would be released into the atmosphere, according to the SFA. Reforestation has also contributed to the growth in China’s domestic timber industry.
China Urged To Restore Entire Ecosystems
But some experts question the sustainability of China’s forestry program, arguing it focuses almost exclusively on plantation forestry and ignores restoration of natural forests.
“The SFA only looks at forested land, but they forget the full picture,” Xu Jianchu, a professor at the Kunming Institute of Botany, Chinese Academy of Sciences, told Reuters.
He said most of the new forested land was low-quality, and pointed out that while new trees are planted rapidly, data shows that forest loss in many areas of China is increasing.
Local authorities often choose to plant non-native species such as fruit trees and rubber in order to maximize economic benefits, instead of opting for trees naturally suited to local areas. In arid and semi-arid regions, this has often worsened soil erosion and water scarcity instead of solving it, adding to food production problems.
“They should also look at agriculture, and treat the ecosystem as a whole,” said Xu.

Sacred Seedlings is a U.S.-based program that supports the vision of local stakeholders. We have projects ready across Africa. We seek additional projects elsewhere around the world. We also seek volunteers, sponsors and donors of cash and in-kind support. Write to Gary Chandler for more information email@example.com
