Forests as big as France have grown back since 2000, research shows

The study found the Atlantic Forest in Brazil regained an estimated 4.2 million hectares — an area roughly the size of the Netherlands — since 2000, something it described as a success story.

From Mongolia to southern Brazil, forests big enough to cover France have grown back during the last 20 years, but the gains did not make up for losses elsewhere, a report showed on Tuesday.

An analysis of satellite data by a team of researchers led by the World Wide Fund for Nature (WWF) revealed that almost 59 million hectares (146 million acres) of forests have regenerated since 2000.

That much forest has the potential to absorb 5.9 gigatonnes of carbon dioxide (CO2) — more than the annual emissions of the United States, according to the study.

“The data show the enormous potential of natural habitats to recover when given the chance to do so,” said John Lotspeich, executive director of Trillion Trees, the coalition of environmental groups behind the study. “But it isn’t an excuse for any of us to wait around for it to happen”.

 

The research looked at forests that have grown back spontaneously or with little human help, such as planting native trees or fencing off land to reduce grazing.

Scientists say that protecting and regenerating forests is a better climate change solution than planting trees, because existing forests absorb more planet warming gasses while also safeguarding wildlife and biodiversity.

“We’ve known for a long time that natural forest regeneration is often cheaper, richer in carbon and better for biodiversity than actively planted forests,” said William Baldwin-Cantello, director of nature-based solutions at WWF-UK. “This research tells us where and why regeneration is happening, and how we can recreate those conditions elsewhere.”

The study found the Atlantic Forest in Brazil regained an estimated 4.2 million hectares — an area roughly the size of the Netherlands — since 2000, something it described as a success story.

 

Over the same period, 1.2 million hectares of boreal forests were regenerated in northern Mongolia, with other reforestation hotspots including central Africa and Canada, it said.

Still, the authors said such “encouraging signs” could not be taken for granted, warning the world was still losing forests at a “terrifying rate”, much faster than that of restoration.

Brazil’s Atlantic Forest was still only about 12% of its original size and needed to more than double to reach what the researchers said was the minimal threshold for lasting conservation.

Overall, separate research has shown that 386 million hectares of tree cover — an area more than seven times larger than that of naturally regenerated forest identified in the study — has been lost globally in the past two decades.

“If we give forests the space ... to regenerate at scale, and if we create that space, and we ensure that last into the future, then this is going to play a major role in avoiding climate change,” Baldwin-Cantello told the Thomson Reuters Foundation in an online call. “It doesn’t mean we don’t need to stop deforestation, we definitely do. It doesn’t mean we don’t need to reduce emissions ... But we need all of these things combined. And we can do much more to capitalize on that regeneration than we currently are.”
