The destruction of tens of thousands of square miles of Earth's tropical forests in 2021 underscores the challenge of fulfilling a pledge made by nations at last year's United Nations Climate Conference to halt deforestation by the end of the decade, a report published Thursday asserted.
"We have to dramatically reduce emissions from all sources."
According to the World Resources Institute's (WRI) Global Forest Review, the planet's tropical regions lost 11.1 million hectares, or 42,857 square miles, of primary old-growth forest in 2021, a total area roughly the size of the country of Bulgaria or the U.S. state of Virginia.
WRI senior fellow Frances Seymour toldThe Guardian that "such losses are a disaster for the climate. They're a disaster for biodiversity. They're a disaster for Indigenous peoples and local communities."
\u201cLast year, tropical primary forest loss resulted in 2.5 Gt of CO2 emissions. That\u2019s equivalent to India\u2019s annual fossil fuel emissions, according to new data from @UMD_GLAD and available on @GlobalForests [2/6]\u201d— Ani Dasgupta (@Ani Dasgupta) 1651157365
The WRI figure includes 3.75 million hectares of tropical primary rainforest loss--described by the report as "areas of critical importance for carbon storage and biodiversity"--or the equivalent of 10 soccer fields per minute. Last year's tropical primary forest loss resulted in the release of 2.5 billion tons of carbon dioxide, the equivalent of India's total annual fossil fuel emissions.
With more than 1.5 million hectares destroyed, Brazil lost the most tropical primary forest by far last year, followed by Congo (499,059 hectares), Bolivia (291,379 hectares), and Indonesia (202,905 hectares). In terms of percentage of tropical primary forest lost, Cambodia led the world with 1.5%, followed by Laos (1%) and Bolivia (0.7%).
\u201cOver 40% of tropical primary forest loss in 2021 occurred in Brazil.\n\nAs the country with the most primary rainforest, Brazil consistently leads the world in forest loss.\n\nRead more about Brazil\u2019s forests on the #GlobalForestReview\n#GenerationRestoration #Initiative20x20\u201d— WRI Restoration (@WRI Restoration) 1651150803
The report also notes record losses of boreal forests, mainly in Russia, which suffered the worst wildfire season in recorded history.
In addition to fueling the climate emergency by releasing greenhouse gases into the atmosphere, deforestation degrades land, increases flooding, alters weather patterns, and harms biodiversity through habitat destruction.
According to the World Wildlife Fund, clearing trees for cattle grazing is by far the leading driver of deforestation, with scientists attributing 80% of Brazilian Amazon rainforest loss to the beef industry.
The report says the world has made little progress toward fulfilling a pledge by more than 140 countries attending COP26--last year's U.N. summit in Glasgow, Scotland--to "halt and reverse forest loss and land degradation by 2030," a goal that "will require a consistent decline in forest loss every year for the rest of the decade--a decline that is not yet happening in the tropics as a whole."
However, the publication does highlight some success stories. Primary forest loss has declined significantly in Indonesia and Malaysia, while countries including Gabon and Guyana have lost 1% or less of their primary forests over the past two decades.
\u201cGood news! Corporate climate commitments + government action to protect forests in Indonesia are working! The country is heading in the right direction to meet some of its climate pledges. \n\nHear from the experts on the #GlobalForestReview\u201d— Global Forest Watch (@Global Forest Watch) 1651151510
The WRI report follows research published last month warning thatthe ability of the Amazon rainforest to recover from droughts and wildfires has been declining over the past two decades, driving the crucial ecosystem toward what authors called a "critical transformation" from forest to grassland, a shift that would have "profound" consequences.
"That would release enough carbon into the atmosphere to blow the Paris agreement goals right out of the water," said Seymour.
"We have to dramatically reduce emissions from all sources," she added. "No one should even think anymore about planting trees instead of reducing emissions from fossil fuels. It's got to be both and it's got to be now before it's too late."
