China announced its plan to fight climate change at Davos 2022. But experts are skeptical.
Environmentalists have raised concerns that reforestation may be used as a fig leaf to obfuscate. “Promoting nature at large scales can be fantastic if done in an ecologically responsible way, but it should not distract from efforts to decarbonize,” says Tom Crowther, an environmental scientist at ETH Zurich. They also point out that China has engaged in vast reforestation work in the past of varying success.
But problems such as land erosion and over-farming stalled efforts in many areas of the Great Green Wall, while chronic water pollution rendered some soil unsuitable to sustain life. There are also concerns over biodiversity since most reforestation efforts have centered on a specific plant species, making the resulting forests unappealing for bird life and susceptible to blights.
