Rates and causes of deforestation vary from region to region around the world. In 2009, 2/3 of the world forests were in 10 top countries: 1) Russia, 2) Brazil, 3) Canada, 4) United States, 5) China, 6) Australia, 7) Congo, 8) Indonesia, 9) Peru and 10) India.
World annual deforestation is estimated as 13.7 million hectares a year, equal to the area of Greece. Only half of this area is compensated by new forests or forest growth. In addition to directly human-induced deforestation, the growing forests have also been affected by climate change, increasing risks of storms, and diseases. Kyoto protocol includes the agreement to prevent deforestation but not the actions to fulfill it.
As of 2008UNEP). Some sources claim that deforestation has already wiped out roughly 90% of West Africa's original forests. Deforestation is accelerating in Central Africa. According to the FAO, Africa lost the highest percentage of tropical forests of any continent during the 1980s, 1990s, and early 2000s. According to the figures from the FAO (1997), only 22.8% of West Africa's moist forests remain, much of this degraded. Nigeria has lost 81% of its old-growth forests in just 15 years (1990-2005). Massive deforestation threatens food security in some African countries. One factor contributing to the continent's high rates of deforestation is the dependence of 90% of its population on wood as fuel for heating and cooking., Africa is suffering deforestation at twice the world rate, according to the United Nations Environment Programme (
Research carried out by WWF International in 2006 shows that in Africa, rates of illegal logging vary from 50% in Cameroon and Equatorial Guinea to 70% in Gabon and 80% in Liberia - where timber revenues played a major role in financing the Sierra Leone Civil War and other regional armed conflicts until the UN Security Council imposed a ban on all Liberian timber in 2003.
Deforestation in the Democratic Republic of the Congo has been caused partly by unregulated logging and mining, but mostly by the demands made by the subsistence activities of a poor population. In the east of the country, for example, more than 3 million people live less than a day's walk from Virunga National Park. Wood from the park's forests is used by many of those people as firewood, as lumber for construction, and in the production of charcoal. Deforestation caused by subsistence living is an acute threat to the park in general, and to the habitat of the critically endangered mountain gorilla in particular. From 2014 to 2018 the rate of tree-felling in the Democratic Republic of Congo has doubled.
The main cause of deforestation in the East African country of Ethiopia is a growing population and subsequent higher demand for agriculture, livestock production and fuel wood. Other reasons include low education and inactivity from the government, although the current government has taken some steps to tackle deforestation. Organizations such as Farm Africa are working with the federal and local governments to create a system of forest management. Ethiopia, the third largest country in Africa by population, has been hit by famine many times because of shortages of rain and a depletion of natural resources. Deforestation has lowered the chance of getting rain, which is already low, and thus causes erosion. Bercele Bayisa, an Ethiopian farmer, offers one example why deforestation occurs. He said that his district was forested and full of wildlife, but that overpopulation caused people to come to that land and clear it to plant crops, cutting all trees to sell as firewood.
Ethiopia has lost 98% of its forested regions in the last 50 years. At the beginning of the 20th century, around 420,000 km² or 35% of Ethiopia's land was covered with forests. Recent reports indicate that forests cover less than 14.2% or even only 11.9% as of 2005 . Between 1990 and 2005, the country lost 14% of its forests or 21,000 km².
In 1963 Kenya had forest cover of some 10 percent; by 2006 it had only 1.7 percent.
Deforestation with resulting desertification, water resource degradation and soil loss has affected approximately 94% of Madagascar's previously biologically productive lands. Since the arrival of humans 2000 years ago, Madagascar has lost more than 90% of its original forest. Most of this loss has occurred since independence from the French, and is the result of local people using slash-and-burn agricultural practices as they try to subsist. Largely due to deforestation, the country is currently unable to provide adequate food, fresh water and sanitation for its fast growing population.
According to the FAO, Nigeria has the world's highest deforestation rate of primary forests. It has lost more than half of its primary forest in the last five years. Causes cited are logging, subsistence agriculture, and the collection of fuel wood. Almost 90% of West Africa's rainforest has been destroyed.
Russia has the largest area of forests of any country on Earth, with around 12 million km2 of boreal forest, larger than the Amazon rainforest. Russia's forests contain 55% of the world's conifers and represent 11% of biomass on Earth. It is estimated that 20,000 km2 are deforested each year. The present scale of deforestation in Russia is most easily seen using Google Earth. Areas nearer to China are most affected, as it is the main market for the timber. Deforestation in Russia is particularly damaging as the forests have a short growing season due to extremely cold winters and therefore will take longer to recover.
Forest loss is acute in Southeast Asia, the second of the world's great biodiversity hot spots. According to a 2005 report conducted by the FAO, Vietnam has the second highest rate of deforestation of primary forests in the world, second to only Nigeria. More than 90% of the old-growth rainforests of the Philippine Archipelago have been cut. Other Southeast Asian countries where major deforestation is ongoing are Cambodia and Laos. According to a documentary by TelePool, the deforestation is being directed by corrupt military personnel and government (forestry services).
Cambodia is one of the world's most forest endowed countries that has not yet been drastically deforested. However, massive deforestation for economic development threatens its forests and ecosystems. As of 2015 , the country has one of the highest rates of deforestation in the world.
Deforestation has directly resulted from poorly managed commercial logging, fuel wood collection, agricultural invasion, and infrastructure and urban development. Indirect pressures include rapid population growth, inequalities in land tenure, lack of agriculture technology, and limited employment opportunities.
The Cambodian government has played a large role in shaping the use of the country's forests. An unusually large area of Cambodia has been designated as protected areas and biodiversity corridors, over 38% (more than 7 million hectares) of the total land mass, but many protections have subsequently been overruled by concessions sold to both national and foreign companies for agroindustrial plantations and mining developments, even in national parks. The government has been broadly criticized domestically and internationally for these contradicting policies, and a general lack of enforcement of environmental laws. They have faced pressures to practice a more sustainable forestry overall. The fate of Cambodia's forests will largely affect local communities that rely on the forests for their livelihood. Around 80% of its population lives in rural areas.Cambodia's primary forest cover fell dramatically from over 70% in 1970 at the end of the Vietnam War to just 3.1% in 2007, when less than 3,220 square kilometers of primary forest remained. Deforestation is proceeding at an alarming rate: nearly 75% of forest loss has occurred since the end of 1990s. In total, Cambodia lost 25,000 square kilometers of forest between 1990 and 2005, 3,340 square kilometer of which was primary forest. As 2016, 87,424 square kilometers of forest remained including 28, 612 square kilometers of evergreen forest, with the result that the future sustainability of Cambodia's forest reserves is under severe threat.
Indonesia had lost over 72% of intact forests and 40% of all forests completely in 2005. Illegal logging took place in 37 out of 41 national parks. The illegal logging costs up to US$4 billion a year. The lowland forests of Sumatra and Borneo were at risk of being wiped out by 2022. According to Transparency International, numerous controversial court decisions in this area have raised concerns about the integrity of the judiciary.
Deforestation in Thailand refers to the conversion of its forested land to other uses. Deforestation numbers are inexact due to the scope of the issue. According to the Royal Forest Department (RFD) in 2019, Thai forests cover 31.6% (102 million rai) of Thailand's landmass. The department claims that forest coverage grew by 330,000 rai in 2018, an area equivalent in size to the island of Phuket. A year earlier, an academic claimed that, since 2016, forested area has declined by 18,000 rai, a significant improvement over the period 2008-2013, when a forested million rai were lost each year. In 1975, the government set a goal of 40% forest coverage--25% natural forest and 15% commercial forest--within 20 years. To achieve that target in 2018, 27 million rai would have to be afforested.
Between 1945 and 1975, forest cover in Thailand declined from 61% to 34% of the country's land area. Over the succeeding 11 years, Thailand lost close to 28% of all of its remaining forests. This means that the country lost 3.1% of its forest cover each year over that period. An estimate by the World Wildlife Fund concluded that between 1973 and 2009, Thailand's forests declined by 43%. The Thai Highlands in northern Thailand, the most heavily forested region of the country, were not subject to central government control and settlement until the second half of the 19th century when British timber firms, notably the Bombay Burmah Trading Corporation and the Borneo Company Limited, entered the teak trade in the late-1880s and early-1890s. The Royal Forest Department, created in 1896 and headed by a British forester until 1925, sought to conserve the forests against the worst business practices of British, Thai, and Chinese timber firms who worked in the region.
During the 20th century, deforestation in Thailand was driven primarily by agricultural expansion, although teak deforestation happened as a direct result of logging. Much of Thailand's recent economic improvement can be attributed to increased agricultural production for export. The country was able to increase production by clearing much of their forest and converting it to cropland.The Thai government is beginning to emphasize forest restoration.
According to a 2005 report conducted by the Food and Agriculture Organization of the United Nations (FAO), Vietnam has the second highest rate of deforestation of primary forests in the world, second only to Nigeria.
As of 2005, 12,931,000 hectares (the equivalent of 39.7% of Vietnam's land cover) was forested, although only 85,000 hectares (0.7% of the land cover) was primary forest, the most biodiverse form of forest.Large areas of Vietnam were deforested during the Vietnam War due to the use of Agent Orange.
This section needs expansion. You can help by adding to it. (June 2010)
Europe has lost more than half of its forests in the past 6,000 years. This has primarily been due to agricultural expansion and demand for wood fuel.
Iceland has undergone extensive deforestation since Scandinavians settled in the ninth century. At the time of human settlement about 1140 years ago, birch forest and woodland covered 'at least 25%' of Iceland's land area. The settlers began by cutting down the forests and burning scrubland to create fields and grazing land. Deforestation did not end in Iceland until the middle of the 20th century. Afforestation and revegetation has restored small areas of land. However, agriculture was the main reason birch forest and woodland did not grow back.
Sicily is an oft-cited example of man-made deforestation, practiced since Roman times, when the island was made an agricultural region, and continued to this day. This gradually aridified the climate, leading to decline of rainfall and drying of rivers. Today, the entire central and southwest provinces are practically without any forests. This has also affected Sicily's wild fauna, of which little is left in the island's pastures and crop fields.

In 2005, an estimated 56,000 hectares were deforested in Canada. Deforestation affected less than 0.02% of Canada's forests in 2005. The agricultural sector accounted for just over half of the deforestation in 2005, the result of forests having been cleared for pasture or crops. The remainder was caused by urban development, transportation corridors, and recreation (19%); hydroelectric development (10%); the forest sector (10%); and other natural resource extraction industries (8%). About two thirds of this deforestation occurred in Canada's boreal forest, mainly in Alberta, Saskatchewan, and Manitoba where the forest borders the Prairies. 
In Canada, prior to 2000, less than 8% of the boreal forest was protected from development and more than 50% has been allocated to logging companies for cutting.
In 1600, prior to the arrival of European-Americans, roughly half of the land area of the present-day United States was forest--about 4,000,000 square kilometres (990,000,000 acres). For the next 300 years land was cleared, mostly for agriculture, at a rate that matched the rate of population growth. For every person added to the population, one to two hectares of land was cultivated. This trend continued until the 1920s when the amount of crop land stabilized in spite of continued population growth. As abandoned farmland reverted to forest, the amount of forestland increased from 1952, reaching a peak in 1963 of 3,080,000 square kilometres (760,000,000 acres). Since 1963 there has been a steady decrease of forest area with the exception of some gains from 1997.
The history of most Central American countries involves cycles of deforestation and reforestation. By the fifteenth century, intensive Mayan agriculture had significantly thinned the forests. Before Europeans arrived, forests covered 500,000 square kilometers - approximately 90% of the region. Eventually, the forcing of "Europe's money economy on Latin America" created the demand for the exportation of primary products, which introduced the need for large amounts of cleared agricultural land to produce those products. Since the 1960s, cattle ranching has become the primary reason for land clearing. The lean grass-fed cattle produced by Central American ranches (as opposed to grain-fed cattle raised elsewhere) was perfectly suited for American fast-food restaurants and this seemingly bottomless market has created the so-called "hamburger connection" which links "consumer lifestyles in North America with deforestation in Central America".
The Amazon rainforest is the largest rainforest in the world, covering an area of 5,500,000 km2 (2,100,000 sq mi). It represents over half of the planet's rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60%, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and France (French Guiana).
The cattle sector of the Brazilian Amazon, incentivized by the international beef and leather trades, has been responsible for about 80% of all deforestation in the region, or about 14% of the world's total annual deforestation, making it the world's largest single driver of deforestation. By 1995, 70% of formerly forested land in the Amazon, and 91% of land deforested since 1970 had been converted to cattle ranching. Much of the remaining deforestation within the Amazon has resulted from farmers clearing land (sometimes using the slash-and-burn method) for small-scale subsistence agriculture or mechanized cropland producing soy, palm, and other crops.
More than one-third of the Amazon forest belongs to more than 3,344 formally acknowledged indigenous territories. Until 2015, only 8% of Amazonian deforestation occurred in forests inhabited by indigenous peoples, while 88% of occurred in the less than 50% of the Amazon area that is neither indigenous territory nor protected area. Historically, the livelihoods of indigenous Amazonian peoples have depended on the forest for food, shelter, water, fibre, fuel and medicines. The forest is also interconnected with their identity and cosmology. For this reason the deforestation rates are lower in indigenous territories, despite pressures encouraging deforestation being stronger. Many indigenous people are being affected by the deforestation in the Amazon. They have their homes here and live off the land, thus when there is deforestation and purposeful fires, it endangers their lives.According to 2018 satellite data compiled by a deforestation monitoring program called Prodes, deforestation has hit its highest rate in a decade. About 7,900 km2 (3,050 sq miles) of the rainforest was destroyed between August 2017 and July 2018. Most of the deforestation occurred in the states of Mato Grosso and Pará. The BBC reported the environment minister, Edson Duarte, as saying illegal logging was to blame, but critics suggest expanding agriculture is also encroaching on the rainforest. It is suggested that at some point the forest will reach a tipping point, where it will no longer be able to produce enough rainfall to sustain itself.
There is no agreement on what drives deforestation in Brazil, though a broad consensus exists that expansion of croplands and pastures is important. Increases in commodity prices may increase the rate of deforestation. Recent development of a new variety of soybean has led to the displacement of beef ranches and farms of other crops, which, in turn, move farther into the forest. Certain areas such as the Atlantic Rainforest have been diminished to just 7% of their original size. Although much conservation work has been done, few national parks or reserves are efficiently enforced. Some 80% of logging in the Amazon is illegal.
In 2008, Brazil's government announced a record rate of deforestation in the Amazon. Deforestation jumped by 69% in 2008 compared to 2007's twelve months, according to official government data. Deforestation could wipe out or severely damage nearly 60% of the Amazon rainforest by 2030, according to a 2007 report from WWF.
Colombia loses 2,000 km2 of forest annually to deforestation, according to the United Nations in 2003. Some suggest that this figure is as high as 3,000 km² due to illegal logging in the region. Deforestation results mainly from logging for timber, small-scale agricultural ranching, mining, development of energy resources such as hydro-electricity, infrastructure, cocaine production, and farming. Around one-third of the country's original forest has been removed as a result of deforestation.Deforestation in Colombia is mainly targeted at primary rainforest which covers more than 80% of Colombia. This has a profound ecological impact in that Colombia is extremely rich in biodiversity, with 10% of the world's species, making it the second most biologically diverse country on Earth.
Due to relatively recent colonisation, Australia has had high rates of deforestation, primarily due to clearing for agricultural purposes. In recent years[when?] much of the clearing has occurred in Tasmania and Queensland. In 2007, rates were expected to decrease with the implementation of new legislation. In 1998, deforestation is thought to have been responsible for around 12% of Australia's total carbon emissions.
An additional factor currently causing the loss of forest cover is the expansion of urban areas. Littoral rainforest growing along coastal areas of eastern Australia is now rare due to ribbon development to accommodate the demand for seachange lifestyles.
Earlier in 2014, there were plans to clear large areas of forests, but that decision was later abandoned.
In the 800 years of human occupation of New Zealand 75% of the forests were lost. Initially it was by wholesale burning by the British but remaining forests were logged for lumber for the burgeoning population. By 2000 all logging of native trees on public land was stopped. Logging on private land is controlled with a permit system and with the Resource Management Act.
