NASA data verify China’s contribution to greening efforts

Standing on a hillside, 46-year-old ranger Huang Xiaobin looks down at the lush landscape that surrounds his village in the remote mountainous areas of the southwestern Jiangxi Province. Terraced slopes that were once barren are now filled with cedars and pine trees.

The landscape has changed a lot since Huang’s grandfather, the first ranger in his family, took the job in 1951. At that time, the fields were just sparsely dotted with bushes.

Inspired by the idea of turning barren hills to green ones, Huang’s father and Huang picked up the batons in succession.

“The landscape looks completely different,” said Huang Xiaobin, who has spent 25 years planting trees and taking care of the forest. “It’s worthwhile,” he said simply, despite the harsh environment and heavy workloads.

Thanks to hundreds of thousands of devoted rangers like the Huang family, China has made huge headway in reforestation over the past decades, contributing enormously to global efforts in fighting soil erosion, air pollution and climate change.

A new study using data from NASA satellites shows that China and India are leading the increase in greening on land and concludes that the “effect comes mostly from ambitious tree-planting programs in China and intensive agriculture in both countries.” The study was published on Feb 11, in the journal Nature Sustainability.

The researchers found that global green leaf area has increased by 5 percent since the early 2000s, an area equivalent to all of the Amazon rainforests. At least 25 percent of that gain came in China.

With almost 1.4 billion mouths to feed, China needs both the land and the timber to fuel its economy. China’s contribution to the global greening efforts comes in large part from its vigorous programs to conserve and expand forests.

China aims to increase the forest cover to 23.04 percent by 2020, and to 26 percent by 2035. To achieve the ambitious goals, the country has taken a slew of measures ranging from reforesting hillsides to creating protected grassland and nature reserves.

After several decades of blistering economic growth, China has realized the damage on the environment and begun to pursue a greener path forward.

Reiterating that “lucid waters and lush mountains are invaluable assets,” Chinese leadership has stressed that the country must embrace eco-friendly models for growth and ways of life. Over the past three years, 44.67 million hectares of state forest farms have been protected. Logging of natural forests has been strictly banned. Consumption of natural forests has fallen 5.56 million cubic meters annually.

The government has also conducted regular quality tests of tree seedlings and established a nationwide resource database of robust seedlings in a bid to ensure that healthy seeds are restored and used.

The notion of the eco-friendly way of life has resonated with the aspiration of the general public, with many individuals actively participating in various greening campaigns.

One of the most popular programs is “Ant Forest,” which was launched in September 2017 by a Hangzhou-based company, Ant Financial Services Group, which has become a feature in the Alipay app, one of the most widely used online payment platforms in China.

Users can claim carbon points for doing environmentally friendly things such as walking, using public transportation, going paperless in the office and more. These points can then be used to water and grow their own virtual saplings. After the virtual saplings have grown to become virtual trees with the constant watering of carbon points, Ant Financial and their charity partners will plant real trees somewhere in the world.

By the end of May last year, the number of Ant Forest subscribers had exceeded 350 million, reducing exhaust equivalent to 3 million tonnes of carbon dioxide. More than 55 million trees had been planted and attended.

“Such programs are quite appealing to me. I feel satisfied to see a real tree planted just by doing some simple things such as riding bicycles and buying tickets online,” said Zhang Jing, a 28-year-old salesperson.
