The world’s rainforests lost 6.7 million hectares of primary tropical forest in 2024, nearly double the amount lost in 2023. That’s the highest annual loss in years, driven by massive fires, expanding agriculture, and a surge in illegal mining. While a few countries in Southeast Asia are making progress, the overall trajectory is heading in the wrong direction, with the Amazon, Congo Basin, and parts of South America bearing the worst of it.
Record-Breaking Forest Loss in 2024
Brazil, home to the largest stretch of tropical forest on Earth, accounted for 42% of all tropical primary forest loss in 2024. The Amazon experienced its highest tree cover loss since 2016, fueled by drought, fire, and land clearing. Bolivia, where pasture and soy expansion have consumed 5.6 million hectares since 2001, continues to see accelerating destruction.
In Central Africa, the Democratic Republic of Congo and the Republic of Congo both hit their highest levels of primary forest loss ever recorded. The Republic of Congo alone saw a 150% surge compared to the previous year. Unsustainable logging, mining, oil exploration, and urban expansion are pushing ecosystems in the Congo Basin toward critical thresholds, compounded by ongoing armed conflicts that make conservation nearly impossible to enforce.
Southeast Asia stands out as a rare bright spot. Indonesia reduced its primary forest loss by 11%, reversing a steady climb between 2021 and 2023. Malaysia saw a 13% decline and dropped out of the top 10 countries for tropical forest loss for the first time. These gains reflect stronger enforcement and policy shifts, though they remain fragile.
Agriculture Is the Dominant Driver
When people picture rainforest destruction, they often think of logging. But agriculture is far and away the biggest cause. Between 2001 and 2024, permanent agriculture accounted for roughly 95% of all deforestation-linked tree cover loss globally, clearing 168 million hectares of forest. That’s an area larger than Mongolia. This includes everything from industrial-scale cattle ranching and soy farming to smallholder plots carved into forest edges.
Mining, while much smaller in total area (less than 1% of global tree cover loss), punches above its weight in specific regions. In Peru, Latin America’s largest gold producer, mining is a significant local driver. And the problem is growing. Rising gold prices have fueled a boom in illegal mining across the Amazon, with unrecorded gold mining accounting for over 86% of mining-related deforestation in Brazil and nearly 100% in Peru, Myanmar, and Guyana. These operations don’t just remove trees. They contaminate rivers with mercury, degrade soil, and threaten the health of Indigenous communities living nearby.
Rainforests Are Losing Their Ability to Generate Rain
One of the most consequential and least understood effects of deforestation is what it does to rainfall. Tropical forests act as massive water pumps: trees pull moisture from the soil and release it into the atmosphere, where it forms clouds and falls again as rain. When large sections of forest disappear, that cycle weakens.
A study published in Nature Communications found that the southern Amazon basin has experienced an 8 to 11% decline in annual rainfall over the past several decades, and 52 to 72% of that reduction is directly linked to deforestation in the region and upwind areas. Some parts of the southern basin have seen rainfall drop by more than 10 millimeters per year, year after year, a compounding loss. The moisture generated by forests has decreased by about 21%, and less of that moisture stays local, meaning the rain that forests once recycled is simply leaving the system.
This matters far beyond the forest itself. Reduced rainfall affects agriculture across South America, threatens water supplies for cities like São Paulo, and creates drier conditions that make remaining forests more vulnerable to fire, which then destroys more forest and reduces rainfall further.
Indigenous Lands Hold the Line
A global study published in Nature Sustainability found that Indigenous peoples’ lands experience roughly a fifth less deforestation than non-protected areas. In Africa, Indigenous lands actually outperform formally designated protected areas at preventing forest loss. In Asia, Indigenous lands and protected areas perform about equally, both reducing deforestation by around 20% compared to unprotected land.
The picture is more complicated in the Americas, where deforestation in Indigenous lands was about 15% higher than in protected areas. That gap likely reflects the intense pressure from agricultural expansion and illegal mining that these communities face, often with limited government support or enforcement. Even so, across the tropics as a whole, Indigenous stewardship remains one of the most effective and cost-efficient forms of forest protection.
Restoration Targets Are Ambitious but Behind Schedule
The international community has set a goal of restoring 350 million hectares of degraded forest by 2030, a target rooted in the Bonn Challenge and the New York Declaration on Forests. To hit that number, global tree cover would need to grow from roughly 4,122 million hectares (the baseline measured in 2000) to 4,472 million hectares by the end of the decade.
Progress has been slow. While many countries have made pledges, the gap between commitments on paper and trees in the ground remains enormous. Restoration is inherently slower than destruction. A hectare of rainforest can be cleared in days, but regrowing a functioning forest ecosystem takes decades. Planted trees don’t immediately replicate the biodiversity, carbon storage, or water cycling of old-growth forest.
Technology Is Changing How We Watch
Satellite monitoring has transformed the ability to detect deforestation in near real time. Platforms like Global Forest Watch use satellite imagery to flag areas where tree cover is disappearing, sometimes within days of clearing. Newer systems are incorporating AI to automatically identify deforestation events from satellite feeds, though the technology is still maturing. Early models using deep learning approaches have shown they can improve detection rates and reduce false alarms, but accuracy remains a work in progress, particularly in cloudy tropical regions where satellite views are frequently obscured.
The value of these tools is less about catching every individual event and more about creating accountability. When deforestation data is public and updated frequently, governments, companies, and consumers can see where destruction is happening and which supply chains are connected to it. That visibility has already contributed to policy changes in Indonesia and Malaysia, and it puts pressure on commodity traders to clean up their sourcing.
What the Numbers Add Up To
The world’s three great rainforest regions are on diverging paths. Southeast Asia is showing that policy enforcement can bend the curve downward. The Congo Basin is losing forest faster than ever, with conflict and weak governance accelerating the damage. And the Amazon, the largest and most critical tropical forest on the planet, is caught between competing pressures: agricultural expansion, illegal mining, drought, and fire, all reinforcing each other in a cycle that reduces the forest’s ability to sustain itself through rainfall.
At 6.7 million hectares lost in a single year, the pace of tropical forest destruction is not slowing globally. It is accelerating. The forests that remain are not just trees. They are the infrastructure that regulates regional climate, stores carbon, cycles water, and supports the livelihoods of hundreds of millions of people. Every hectare lost makes the remaining forest more vulnerable, and the math only gets harder from here.
