how many trees are cut down each year

Latin America exports around 23% of its emissions; that means more than three-quarters are generated for products that are consumed within domestic markets. Nicolas-Jacques Cont, an officer in Napoleon's army, invented the modern pencil by combining graphite and clay for lead durability. Then things started to speed up. You see that of the 14.9 billion hectares of land on the planet, only 71% of it is habitable the other 29% is either covered by ice and glaciers, or is barren land such as deserts, salt flats, or dunes. WebThe UN FAO estimate that 10 million hectares of forest were cut down each year. Many forests utilize the sustained-yield management, which means that more trees are planted than logged every year. In the map we see the net deforestation embedded in trade for each country. The study also finds that human activity negatively affects tree abundance from the boreal forests to the equator. In a related post we have combined this FAO data with global deforestation rates from Williams (2003) to document forest change over the last 300 years this gives us data on forest change from 1700 onwards. are added every year. An assessment of deforestation and forest degradation drivers in developing countries. Cuaresma, J. C., Danylo, O., Fritz, S., McCallum, I., Obersteiner, M., See, L., & Walsh, B. Scheffers, B. R., Joppa, L. N., Pimm, S. L., & Laurance, W. F. (2012). Some interesting facts state that every second, 1.5 acres of wood are cut down, And to identify where deforestation is occurring; perhaps as important, show where forest loss is not deforestation. Most deforestation occurs for the production of goods that are consumed within domestic markets. See which countries are gaining forest though natural forest expansion and afforestation. Firstly, international trade does play a role in deforestation its responsible for almost one-third of emissions. In China, the biggest driver is demand for oilseeds which is the combination of soy imported from Latin America and palm oil, imported from Indonesia and Malaysia. This is probably less than many people would expect. Science, 361(6407), 1108-1111. Tropical forests are also large carbon sinks, and can store a lot of carbon per unit area.26. From this understanding we can define five reasons why we lose forests: Thanks to satellite imagery, we can get a birds-eye view of what these drivers look like from above. We then get high-income countries share of deforestation as: [40% of the 29% that is traded], which is equal to 12%. It doesnt capture trees that are cut down in planted forests; the land is still forested, its now just regrowing forest. In contrast, most forest degradation two-thirds of it occurs in temperate countries. Forest transition theory and the reforesting of Scotland. A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion. The research says 15.3 billion trees are chopped down every year. On the x-axis we have imported deforestation. This diagram is adapted from the work of Hosonuma et al. By the 19th century the forest area was reduced to a third of what it once was. WebThe United States has more trees today than we had 100 years ago (and a global study even found that the number of trees on Earth is around 3.04 trillion, a much higher number than previously believed.) You will notice in the chart that this was not only expanding into previously forested land, but also other land uses such as wild grasslands and shrubbery. How many trees are cut down each year? The researchers found that 36 million trees are cut down in urban areas each year, and 167,000 acres of impervious areas (concrete, asphalt, etc.) (2018), published in Science.20, Commodity-driven deforestation and urbanization are deforestation: the forested land is completely cleared and converted into another land use a farm, mining site, or city. Many farmers rely on international buyers to earn a living and improve their livelihoods. Rudel, T. K. (1998). Explore palm oil production across the world, and its impacts on the environment. In Latin America and Southeast Asia in particular, commodity-driven deforestation mainly the clearance of forests to grow crops such as palm oil and soy, and pasture for beef production accounts for almost two-thirds of forest loss. Environmental Research Letters, 7(4), 044009. This increase was mostly driven by tropical deforestation as countries across Asia and Latin America followed the path of Europe and North America. Rome. How Many Acres of Trees Are Cut Down Each Year? Then things started to speed up. When in history did we lose it? Science, 349(6250), 827-832.Williams, D. R., Clark, M., Buchanan, G. M., Ficetola, G. F., Rondinini, C., & Tilman, D. (2020). There are other aspects to consider. Increasing human dominance of tropical forests. If we sum countries imported deforestation by World Bank income group, we find that high-income countries were responsible for 40% of imported deforestation; upper-middle income for 25%; lower-middle income for 20%; and low income for 5%.We then get high-income countries share of deforestation as: [40% of the 29% that is traded], which is equal to 12%. The research says 15.3 billion trees are chopped down every year. The scale of deforestation today might give us little hope for protecting our diverse forests. Agricultural and forestry trade drives large share of tropical deforestation emissions. Thats a lot of trees! From 1700 to 1850, 19 million hectares were being cleared every decade. and an argument for why deforestation is worse than degradation. Many countries have not only ended deforestation, but actually achieved substantial reforestation. They are smaller, and more temporary. As to the number of trees this represents, its impossible to get an accurate count. Across Africa, fuelwood and charcoal played a much larger role it accounted for more than half (52%). Improvements in crop yields mean the per capita demand for agricultural land continues to fall. University of Chicago Press.FAO (2020). They first lose lots of forest, but reach a turning point and begin to regain it again. All other material, including data produced by third parties and made available by Our World in Data, is subject to the license terms from the original third-party authors. The paths between these end boxes indicate where emissions are being traded the wider the bar, the more emissions are embedded in these products. Growing all those trees requires about 19.7 square miles of land. In the chart here we see the breakdown of deforestation emissions by product for each consumer country. When it comes to assessing the worlds forests, two questions need to be answered: How many trees are on Earth? and. Healthy environment: One hundred mature trees catch about 139,000 gallons of rainwater per year. Note that in this study, the category of subsistence agriculture was classified as a deforestation driver, and so is not included. How many trees have been cut down? Some interesting facts state that every second, 1.5 acres of wood are cut down, Data from 1990 onwards is sourced from the UNs 2020 Global Forest Resources Assessment 2020.References:Williams, M. (2003). What are the major impacts of mass deforestation and forest loss? On the horizontal axis we have time, spanning from 1700 to 2020; on the vertical axis we have the decadal change in forest cover. This is true for some problems, such as climate change. How many trees are lost to deforestation each year? The Earth System (Vol. The rate of forest loss changed a lot. Since there is often year-to-year variability in deforestation or reforestation rates, this is shown as the five-year average. National Inventory of Woodland and Trees, England (2001). Environmental impacts of food consumption in Europe. How many trees have been cut down? 1000 years ago, 20% of Scotlands land was covered by forest. The default is shown for Brazil, but you can explore the data for a range of countries using the Change country button. Thats an area 1.5-times the size of the United States. Imagine some temperate country was responsible for the deforestation of 25,000 hectares in tropical countries but was restoring its own forests at a rate of 50,000 hectares per year. The Forest Transition therefore tends to follow a development pathway.16 As a country achieves economic growth it moves through each of the four stages. Countries below the line such as the UK and Germany are not growing forests fast enough to offset the deforestation theyre creating elsewhere. The UN Food and Agriculture Organization (FAO) Forest Resources Assessment estimates global deforestation, averaged over the five-year period from 2015 to 2020 was 10 million hectares per year. The United Nations, as well as experts at the World Wildlife Fund and Global Forest Watch, found that one million animals are in danger of extinction as a result of how much deforestation has occurred. They also contribute to global deforestation through the foods they import from poorer countries. Over half of the worlds species reside in tropical forests.24 Endemic species are those which only naturally occur in a single country. This rapid swapping of green for gray is harmful to the people living in these spaces, and it sets cities up for long-term environmental decline, according to the scientists. At this stage, countries are still losing forest each year but at a lower rate than before. If we can identify the producer countries, importing countries, and specific products responsible, we can direct our efforts towards interventions that will really make a difference. Forest degradation measures a thinning of the canopy a reduction in the density of trees in the area but without a change in land use. The taller the bar, the larger the change in forest area. After we adjust for imports and exports, how much CO2 from deforestation is each country responsible for? The rate of deforestation is declining, but we still lost forests at a whopping 10 million hectares per year between 2015-2020. Still, more than half of the worlds habitable land was forested. The data used in this chart comes from several sources. According to CNN, each year over 1,000 plants and animal species go extinct due to deforestation and subsequent habitat loss. The problem is that it treats all forest loss as equal. Ellis, E. C., Beusen, A. H., & Goldewijk, K. K. (2020). The researchs results are But distilling changes to this single metric tree or forest loss comes with its own issues. Imagine over 100 large harvesters working non-stop. Rural Sociology, 63(4), 533-552. Net forest loss is not the same as deforestation it measures deforestation plus any gains in forest over a given period. Noriko Hosonuma et al. Rome. Why? Then, using a physical trade model across 191 countries and around 400 food and forestry products, they could trace them through to where they are physically consumed, either as food or in industrial processes.Pendrill, F., Persson, U. M., Godar, J., Kastner, T., Moran, D., Schmidt, S., & Wood, R. (2019). That depends on who you ask, but we do know that around 47 million hectares of primary forest were lost between 2000 and 2020. Proactive conservation to prevent habitat losses to agricultural expansion. 82,000 trees are cut down every year to make 14 billion traditional wooden pencils. Notarnicola et al. Thats one football field of forest lost every single second around the clock. Are they causing more deforestation elsewhere than they are regenerating in forests at home? A new study published in Nature estimates the planet has 3.04 trillion trees. Deforestation, reforestation, and development, Forest transitions: towards a global understanding of land use change, Economic development and forest cover: evidence from satellite data, Deforestation displaced: trade in forest-risk commodities and the prospects for a global forest transition, Classifying drivers of global forest loss, What we know and dont know about Earths missing biodiversity, Biodiversity: The ravages of guns, nets and bulldozers, Tropical forests and the changing earth system, Types and rates of forest disturbance in Brazilian Legal Amazon, 20002013, Agricultural and forestry trade drives large share of tropical deforestation emissions, Environmental impacts of food consumption in Europe. High-income countries were the largest importers of deforestation, accounting for 40% of it. Journal of Rural Studies, 15(1), 65-90.Mather, A. S., & Needle, C. L. (2000). The story of both soy and palm oil are complex and its not obvious that eliminating these products will fix the problem. Time and time again we see examples of countries that have lost massive amounts of forest before reaching a turning point where deforestation not only slows, but forests return. If we look at where countries are in their transition today we can understand where we expect to lose and gain forest in the coming decades. If we sum countries imported deforestation by World Bank income group, we find that high-income countries were responsible for 14% of imported deforestation; upper-middle income for 52%; lower-middle income for 23%; and low income for 11%. In most rich countries, across Europe, North America and East Asia, forest cover is increasing, whilst in many low-to-middle income countries its decreasing. This often comes at the cost of forests. Healthy communities: Tree-filled neighborhoods lower levels of domestic violence and are safer and more sociable. Thats both an economic and environmental win. Brazil, in contrast, caused more deforestation domestically in the production of goods for other countries than it imported from elsewhere. Urbanization, the other driver of deforestation accounts for just 0.6%. Maxwell, S. L., Fuller, R. A., Brooks, T. M., & Watson, J. E. (2016). The total cut down so far is over 470 million trees since January 1st. According to the Environmental Paper Network, an estimated 30% of felled trees are used for paper products. The researchers found that 36 million trees are cut down in urban areas each year, and 167,000 acres of impervious areas (concrete, asphalt, etc.) Many countries have much less forest today than they did in the past. On balance, it would still have a positive impact on the size of global forests; its net contribution would be increasing forest area by 25,000 hectares.32 However, this country might still be causing more damage than this for a couple of reasons. But it was then that England reached its transition point and since then, forests have doubled in size. Many countries have followed this classic U-shaped pattern. Web3.5 billion to 7 billion trees are cut down per year. It would be good if there was data available that would capture these additional aspects. 71% of deforestation is for domestic production. What if this deforestation is being driven by consumers elsewhere? This number comes from the World Bank, which estimates that there are 3 trillion trees on the planet. Global forest resources. The world passed peaked deforestation in the 1980s and it has been on the decline since then we take a look at rates of forest loss since 1700 in our follow-up post. Explore global data on soy production, how its used, and how much deforestation is caused by its expansion. Since the end of the last great ice age 10,000 years ago the world has lost one-third of its forests.5 Two billion hectares of forest an area twice the size of the United States has been cleared to grow crops, raise livestock, and use for fuelwood. The rate of deforestation is declining, but we still lost forests at a whopping 10 million hectares per year between 2015-2020. Thats a lot of trees! This is shortly after the end of the last great ice age, through to the present day.2. Rudel, T. K., Coomes, O. T., Moran, E., Achard, F., Angelsen, A., Xu, J., & Lambin, E. (2005). Forests still cover about 30 percent of the worlds land area, but they are disappearing at an alarming rate. How many trees are lost to deforestation each year? The carbon footprint of diets across the EU vary from country-to-country, and estimates vary depending on how much land use change is factored into these figures. International trade is important for socioeconomic development. Several studies have assessed the stage of countries across the world.17 The most recent analysis to date was published by Florence Pendrill and colleagues (2019) which looked at each countrys stage in the transition, the drivers of deforestation but also the role of international trade.18 To do this, they used the standard metrics discussed in our theory of forest transitions earlier: the share of land that is forested, and the annual change in forest cover. By combining our earlier Sankey diagram, and breakdown of emissions by product, we can see that we can tackle a large share of these emissions through only a few key trade flows. How many trees are lost to deforestation each year? If we sum countries imported deforestation by World Bank income group, we find that high-income countries were responsible for 40% of imported deforestation; upper-middle income for 25%; lower-middle income for 20%; and low income for 5%. The breakdown of forest loss globally, and by region, is shown in the chart.22. The biodiversity of managed tree plantations which are periodically cut, regrown, cut again, then regrown is not the same. The latter will experience short-term environmental impacts, but will ultimately regrow. The net change in forest cover measures any gains in forest cover either through natural forest expansion or afforestation through tree-planting minus deforestation. Rome. Forests still cover about 30 percent of the worlds land area, but they are disappearing at an alarming rate. It was predominantly temperate forests that were being lost at this time. Thats around half the size of Germany. The United States is the worlds largest consumer (and second largest producer, after Canada) of forest products. Since year-to-year changes in forest cover can be volatile, the UN FAO provide this annual data averaged over five-year periods. Given the current estimate of the total tree cover on the planet, that could equate to about 0.11% of trees being cut each year. Cutting them down disrupts or destroys established, species-rich ecosystems. FAO. More than 7 million hectares of forest, or 3.5 billion to 7 billion trees, are cut down every year because of deforestation. Forest Transitions: why do we lose then regain forests? Types and rates of forest disturbance in Brazilian Legal Amazon, 20002013. The amount of land per person that was needed to produce enough food was not small in fact, it was much larger than today. Given the current estimate of the total tree cover on the planet, that could equate to about 0.11% of trees being cut each year. Another way that richer countries can contribute is by investing in technologies such as improved seed varieties, fertilizers and agricultural practices that allow farmers to increase yields. Imported emissions are also high for Taiwan, Belgium and the Netherlands at around one tonne. Hosonuma et al. Lets start at the top. For the last two centuries forests have been growing and are almost back to where they were 1000 years ago.13. 27% of forest loss results from commodity-driven deforestation cutting down forests to grow crops such as soy, palm oil, cocoa, to raise livestock on pasture, and mining operations. Stage 2 The Early Transition phase is when countries start to lose forests very rapidly. Imagine over 100 large harvesters working non-stop. Given the current estimate of the total tree cover on the planet, that could equate to about 0.11% of trees being cut each year. [2] Only 36% of the world's rainforests remain intact. We see very clearly that the large Brazilian footprint is driven by its domestic demand for beef. The diet of the average Brazilian creates 2.7 tonnes of CO2 from deforestation alone. The research says 15.3 billion trees are chopped down every year. The data produced by third parties and made available by Our World in Data is subject to the license terms from the original third-party authors. The world has lost one-third of its forests, but an end of deforestation is possible. Thats one football field of forest lost every single second around the clock. By 1900, there were 1.65 billion people in the world (five times fewer than we have today) but for most of the previous period, humans were deforesting the world with only tens or hundreds of millions. Across the US and Europe the breakdown of products is more varied. Stage 3 The Late Transition phase is when deforestation rates start to slow down again. How much deforestation happens every day? Deforestation in Africa is mainly driven by local populations and markets; only 9% of its emissions are exported. But it can bridge between deforestation and degradation depending on the timeframe and permanence of these agricultural practices. They should keep their domestic reforestation targets in perspective with their net impact on global forests. Global Forest Resources Assessment 2020: Main report. Some countries within this group are still far behind peak deforestation: without concerted effort to protect these forests it could be many decades before forests in those countries approach the transition point [as we show in a related post].10.
