Deforestationis the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction.

Today, the greatest amount of deforestation is occurring in tropical rainforests, aided by extensive road construction into regions that were once almost inaccessible. Building or upgrading roads into forests makes them more accessible for exploitation. Slash-and-burn agriculture is a big contributor to deforestation in the tropics. With this agricultural method, farmers burn large swaths of forest, allowing the ash to fertilize the land for crops. The land is only fertile for a few years, however, after which the farmers move on to repeat the process elsewhere. Tropical forests are also cleared to make way for logging, cattle ranching, and oil palm and rubber tree plantations.


Deforestation can result in more carbon dioxide being released into the atmosphere. That is because trees take in carbon dioxide from the air for photosynthesis, and carbon is locked chemically in their wood. When trees are burned, this carbon returns to the atmosphere as carbon dioxide. With fewer trees around to take in the carbon dioxide, this greenhouse gas accumulates in the atmosphere and accelerates global warming.


More immediately, the loss of trees from a forest can leave soil more prone to erosion. This causes the remaining plants to become more vulnerable to fire as the forest shifts from being a closed, moist environment to an open, dry one.

On 29 June 2023, the Regulation on deforestation-free products entered into force. The main driver of these processes is the expansion of agricultural land that is linked to the production of commodities like cattle, wood, cocoa, soy, palm oil, coffee, rubber, and some of their derived products, such as leather, chocolate, tyres, or furniture. As a major economy and consumer of these commodities linked to deforestation and forest degradation, the EU is partly responsible for this problem and it wants to lead the way to solving it.


Under the Regulation, any operator or trader who places these commodities on the EU market, or exports from it, must be able to prove that the products do not originate from recently deforested land or have contributed to forest degradation.


The Regulation on deforestation-free products repeals the EU Timber Regulation. As of 29 June 2023, operators and traders will have 18 months to implement the new rules. Micro and small enterprises will enjoy a longer adaptation period, as well as other specific provisions.


The European Commission organises frequent meetings with EU Member States, selected interested parties (mainly trade and business associations and NGOs), third countries to present and discuss the main strands of work and identify best practices.


A Fitness Check of the EUTR and the FLEGT Regulation was performed in 2021 to evaluate their implementation and functioning, and assess if they were fit for purpose to halt illegal logging and associated trade.


Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use.[1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present.[2] This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century.[3] Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute.[4] Estimates vary widely as to the extent of deforestation in the tropics.[5][6] In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.[7][8]


The direct cause of most deforestation is agriculture by far.[9] More than 80% of deforestation was attributed to agriculture in 2018.[10] Forests are being converted to plantations for coffee, palm oil, rubber and various other popular products.[11] Livestock grazing also drives deforestation. Further drivers are the wood industry (logging), urbanization and mining. The effects of climate change are another cause via the increased risk of wildfires (see deforestation and climate change).


Deforestation results in habitat destruction which in turn leads to biodiversity loss. Deforestation also leads to extinction of animals and plants, changes to the local climate, and displacement of indigenous people who live in forests. Deforested regions often also suffer from other environmental problems such as desertification and soil erosion.


Another problem is that deforestation reduces the uptake of carbon dioxide (carbon sequestration) from the atmosphere. This reduces the potential of forests to assist with climate change mitigation. The role of forests in capturing and storing carbon and mitigating climate change is also important for the agricultural sector.[12] The reason for this linkage is because the effects of climate change on agriculture pose new risks to global food systems.[12]


Since 1990, it is estimated that some 420 million hectares of forest have been lost through conversion to other land uses, although the rate of deforestation has decreased over the past three decades. Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down from 16 million hectares per year in the 1990s. The area of primary forest worldwide has decreased by over 80 million hectares since 1990. More than 100 million hectares of forests are adversely affected by forest fires, pests, diseases, invasive species, drought and adverse weather events.[13]


Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or negative, depending on whether gains exceed losses, or vice versa.[14]


Deforestation is more extreme in tropical and subtropical forests in emerging economies. More than half of all plant and land animal species in the world live in tropical forests.[21] As a result of deforestation, only 6.2 million square kilometres (2.4 million square miles) remain of the original 16 million square kilometres (6 million square miles) of tropical rainforest that formerly covered the Earth.[19] More than 3.6 million hectares of virgin tropical forest was lost in 2018.[22]


In 2023, the Global Forest Watch reported a 9% decline in tropical primary forest loss compared to the previous year, with significant regional reductions in Brazil and Colombia overshadowed by increases elsewhere, leading to a 3.2% rise in global deforestation. Massive wildfires in Canada, exacerbated by climate change, contributed to a 24% increase in global tree cover loss, highlighting the ongoing threats to forests essential for carbon storage and biodiversity. Despite some progress, the overall trends in forest destruction and climate impacts remain off track.[27]


Global deforestation[31] sharply accelerated around 1852.[32][33] As of 1947, the planet had 15 to 16 million km2 (5.8 to 6.2 million sq mi) of mature tropical forests,[34] but by 2015, it was estimated that about half of these had been destroyed.[35][21][36] Total land coverage by tropical rainforests decreased from 14% to 6%. Much of this loss happened between 1960 and 1990, when 20% of all tropical rainforests were destroyed. At this rate, extinction of such forests is projected to occur by the mid-21st century.[citation needed]


In the early 2000s, some scientists predicted that unless significant measures (such as seeking out and protecting old growth forests that have not been disturbed)[34] are taken on a worldwide basis, by 2030 there will only be 10% remaining,[32][36] with another 10% in a degraded condition.[32] 80% will have been lost, and with them hundreds of thousands of irreplaceable species.[32]


Estimates vary widely as to the extent of deforestation in the tropics.[5][6] In 2019, the world lost nearly 12 million hectares of tree cover. Nearly a third of that loss, 3.8 million hectares, occurred within humid tropical primary forests, areas of mature rainforest that are especially important for biodiversity and carbon storage. This is equivalent to losing an area of primary forest the size of a football pitch every six seconds.[7][8]


A 2002 analysis of satellite imagery suggested that the rate of deforestation in the humid tropics (approximately 5.8 million hectares per year) was roughly 23% lower than the most commonly quoted rates.[40] A 2005 report by the United Nations Food and Agriculture Organization (FAO) estimated that although the Earth's total forest area continued to decrease at about 13 million hectares per year, the global rate of deforestation had been slowing.[41][42] On the other hand, a 2005 analysis of satellite images reveals that deforestation of the Amazon rainforest is twice as fast as scientists previously estimated.[43][44]


From 2010 to 2015, worldwide forest area decreased by 3.3 million ha per year, according to FAO. During this five-year period, the biggest forest area loss occurred in the tropics, particularly in South America and Africa. Per capita forest area decline was also greatest in the tropics and subtropics but is occurring in every climatic domain (except in the temperate) as populations increase.[45]
