Tropical forest loss dropped 9 percent last year, but growing threats remain

Share

Global Forest Watch recently reported a complex situation for tropical forests worldwide, revealing both advancements and ongoing challenges in forest conservation. In 2023, the world lost approximately 9.2 million acres of tropical old-growth forests, an area exceeding the size of Maryland.

Despite this, the rate of forest loss has decreased by 9% compared to 2022, signaling some progress in preserving these critical ecosystems important for carbon storage and biodiversity.

Mikaela Weisse, director of Global Forest Watch, noted significant reductions in primary forest loss in Brazil and Colombia, with decreases of 36% and 49%, respectively.

However, she highlighted that these positive trends were overshadowed by increased deforestation and forest fires in countries like Bolivia, Nicaragua and Laos, impacting the overall progress in tropical forest conservation.

“This year we found really significant decreases in primary forest loss in Brazil and in Colombia, but unfortunately those decreases weren’t enough to actually reduce the overall rate of forest loss in the tropics,” Weisse said. “The decreases were counteracted by increases instead in countries like Bolivia, Nicaragua and Laos.”

Weisse also pointed out that Bolivia faces unique challenges with forest fires and agricultural expansion — often promoted by the government — posing significant threats to forest conservation efforts.

Fires and deforestation are identified as the main drivers of forest loss, critical to the global carbon capture cycle. From 2001 to 2021, forests managed by Indigenous peoples in the Amazon have been notably effective as carbon sinks, removing approximately 370 million tons of CO2 from the atmosphere annually. That is equivalent to the United Kingdom’s yearly fossil fuel emissions.

Over the past 40 to 50 years, nearly 17% of the Amazon rainforest has been converted, primarily into agricultural land. Experts warn that surpassing a 20% deforestation threshold could drastically alter the Amazon, transforming it into savanna-like terrain and potentially releasing about 99 billion tons of CO2 into the atmosphere — more than double the annual global emissions from fossil fuels.

Additionally, researchers have expressed concern that the global community is unlikely to meet the 2030 goal of halting and reversing forest loss due to deforestation, a commitment made by over 145 countries and territories in 2021.

“So Global Forest Watch tracks every year the amount of forest loss happening around the world.”

NEWLY RELEASED DATA FROM GLOBAL FOREST WATCH POINTED TO A MIXED OUTLOOK FOR TROPICAL FORESTS ACROSS THE WORLD. 

THE WORLD SAW A LOSS OF 9.2 MILLION ACRES OF TROPICAL OLD-GROWTH FORESTS IN 2023 — AN AREA LARGER THAN THE STATE OF MARYLAND. 

THE GOOD NEWS? THE LOSS OF THESE ECOSYSTEMS, VITAL FOR BOTH CARBON STORAGE AND BIODIVERSITY, ACTUALLY DECREASED 9% FROM THE PREVIOUS YEAR.

BRAZIL AND COLOMBIA MADE SIGNIFICANT PROGRESS, WITH BRAZIL SEEING A 36% REDUCTION AND COLOMBIA A 49% DECREASE IN PRIMARY FOREST LOSS. HOWEVER FOREST FIRES AND DEFORESTATION IN OTHER COUNTRIES, LIKE BOLIVIA AND LAOS, LAST YEAR OFFSET THE PROGRESS IN PROTECTING TROPICAL FORESTS.

FIRES AND DEFORESTATION ARE THE MAIN DRIVERS OF FOREST LOSS — FORESTS ARE CRUCIAL FOR ABSORBING CARBON DIOXIDE FROM THE AIR.

ACCORDING TO THE WORLD RESOURCES INSTITUTE FROM 2001 TO 2021, FORESTS UNDER THE STEWARDSHIP OF INDIGENOUS PEOPLES IN THE AMAZON HAVE BEEN PARTICULARLY EFFECTIVE CARBON SINKS — REMOVING ROUGHLY 370 MILLION TONS OF CO2 FROM THE ATMOSPHERE EVERY YEAR. THAT’S AS MUCH AS THE UNITED KINGDOM EMITS.

IN THE LAST 40-50 YEARS, ABOUT 17% OF THE AMAZON RAINFOREST HAS BEEN CLEARED, PRIMARILY FOR AGRICULTURE. SCIENTISTS CAUTION THAT DEFORESTATION EXCEEDING 20% COULD TRANSFORM THE DENSE FOREST INTO A SAVANNAH, POTENTIALLY RELEASING AROUND 99 BILLION TONS OF CO2—MORE THAN TWICE THE GLOBAL ANNUAL FOSSIL FUEL EMISSIONS.

“Bolivia is interesting, there are a couple of different factors that play. Forest fires are a really big factor in Bolivia and have been in the past several years and this year, in particular, we are seeing fires pop up in areas where they haven’t been in the past.

And at the same time we are seeing a lot of agriculture continuing to come into the country and the government actually promoting that agriculture expansion in a lot of cases”

RESEARCHERS HAVE DISCOVERED THAT THE WORLD IS LIKELY TO NOT MEET A 2030 TARGET TO STOP AND REVERSE THE LOSS OF FORESTS CAUSED BY DEFORESTATION. IN 2021, OVER 145 COUNTRIES AND TERRITORIES COMMITTED TO THIS GOAL.
