Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 countries: Russia, Brazil, Canada, the United States, China, Australia, the Democratic Republic of the Congo, Indonesia, India, and Peru.

Global annual deforestation is estimated to total 13.7 million hectares a year, similar to the area of Greece. Half of the area experiencing deforestation consists of new forests or forest growth. In addition to direct human-induced deforestation, growing forests have also been affected by climate change. The Kyoto Protocol includes an agreement to prevent deforestation, but does not stipulate actions to fulfil it.

Africa By 2008, deforestation in Africa was estimated to be occurring at twice the world average rate, according to the United Nations Environment Programme (UNEP). Some sources claim that deforestation has already wiped out roughly 90% of West Africa's original forests. Today, deforestation is accelerating in Central Africa. According to the United Nations' Food and Agriculture Organization (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 them degraded. Nigeria has lost 81% of its old-growth forests in just 15 years (1990–2005).

Mass deforestation threatens food security in some African countries. One factor contributing to the continent's high deforestation rates is the dependence of 90% of its population on wood as fuel for heating and cooking. Research carried out by the World Wide Fund for Nature (WWF) in 2006 shows that rates of illegal logging in Africa 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.

The Democratic Republic of the Congo

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, lumber for construction, and for the production of charcoal. Deforestation caused by subsistence farming is an acute threat to the park in general, and the habitat of the critically endangered mountain gorilla in particular.These deforesting activities have been amply documented by numerous authors (Accion contra el Hambre, 1999; Biswas & Tortajada-Quiroz, 1996; Fuelwood Crisis Consortium, 1994; Henquin & Blondel, 1996; Lodhi et al., 1998; Blondel, 1997; Leusch, 1995; and Languy, 1995). From 2014 to 2018, the rate of tree-felling in the Democratic Republic of Congo doubled.

Ethiopia

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 biofuel.Sucoff, E. (2003). "Deforestation". Environmental Encyclopedia. pp. 358–359. Detroit: Gale. 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.Parry, J. (2003). Ethiopia, the second largest country in Africa by population, has been hit by famine many times because of shortages of rain and depletion of natural resources. Deforestation has lowered the chance of getting rain, which is already low, and increased erosion. Berkeley Bayisa, an Ethiopian farmer, offers one example of why deforestation occurs. He reported that his district was once forested and full of wildlife, but that overpopulation caused people to come 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 or 35% of Ethiopia's land was covered with forests. Recent reports indicate that forests now cover less than 14.2% or even only 11.9% . Between 1990 and 2005, the country lost 14% of its forests or .

Kenya

In 1963, Kenya had a forest cover of some 10 percent; by 2006, it had only 1.7 percent. Between 2000 and 2020 Kenya experienced a 6% net loss in tree cover, dropping by -285kha (2850000000 m2).

Madagascar

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.

Nigeria

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. The causes cited are logging, subsistence agriculture, and the collection of fuelwood. Almost 90% of West Africa's rainforest has been destroyed.

Asia East Asia Japan Yoichi Kuroda sketches a history and current outline of 'large scale land and landscape destruction' due to industrial timber and paper demands.

North Asia Russia

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 are deforested each year. Areas nearer to China are most affected, as it is the main source for timber. Deforestation in Russia is particularly damaging as the forests have a short growing season due to extremely cold winters and therefore take longer to recover.

South Asia India

Sri Lanka

Southeast Asia

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, deforestation is being directed by corrupt military personnel and the government (forestry services).

Cambodia

Indonesia

, at present rates, rainforests in Indonesia would be logged out in 10 years, Papua New Guinea in 13 to 16 years.

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. 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.

Europe

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. According to satellite data, the loss of biomass in EU's forests increased by 69% in the period from 2016 to 2018, compared with the period from 2011 to 2015.

Finland

Iceland Prior to the deforestation of Iceland in the Middle Ages, some 40% of the land was forested. Today, the country is about 2% forested, with the Icelandic Forest Service aiming to increase that share to 10% through reforestation and natural regrowth.

Iceland has undergone extensive deforestation since Scandinavians settled in the ninth century. At the time of human settlement about 1,150 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 shrubland to create fields and grazing land. Deforestation did not end in Iceland until the middle of the 20th century. Afforestation and revegetation have restored small areas of land. However, agriculture was the main reason birch forests and woodland did not grow back.

Ireland Ireland was historically a temperate rainforest with 80% of the island under tree cover. Deforestation by humans began taking place already in the Bronze Age but reached its peak under British colonial rule, particularly the 16th and 17th century Plantations, that saw mass scale deforestation to create agricultural lands, and to supplement the need for timber for shipbuilding for Britain's early phase of empire building. Tree cover reached its lowest point of 1.5% at the beginning of the twentieth century, prior to Irish independence, due to more industrialised sawmills used in late nineteenth century. The Irish state promoted reforestation during the 20th century, reversing the trend (albeit primarily via plantations of non-native conifers intended for felling), with an increase to 12% tree cover today, which still however remains one of the lowest percentages in Europe, where the average is 39%.

Italy Sicily is an oft-cited example of man-made deforestation, practiced since Roman times when the island was made into an agricultural region, and continued to this day. Deforestation gradually modified the climate, leading to a decline in rainfall and the 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.

Netherlands

The Netherlands, once home to forests and marshes, has also experienced deforestation. The remaining forests and marshes are strictly regulated by staatsbosbeheer (or in English: state forest management) and crisscrossed by service roads and cycling paths. But they are also protected by the Dutch government with the government taking action with many national parks and protected regions.

Russia

United Kingdom

Nearly all forests in the UK have been turned into pasture over the centuries. , 13.2% (3.2 million ha) of the UK is woodland which is an increase from 12% in 1998. However, much of the increased cover is non-native trees. A bucolic, rolling landscape has replaced the idea of true forests in the minds of most Britons.

North America Caribbean Haiti

Central America

The history of most Central American countries involves cycles of deforestation and reforestation. By the 15th century, intensive Mayan agriculture had significantly thinned the forests. Before Europeans arrived, forests covered 500,000 square km– 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".
