[4] Forests cover 4.06 billion hectares (just less than 31%) of Nearly half (47%) of France was forested 1000 years ago; today thats just under one-third (31.4%). How many trees does IKEA cut down a When deforestation happens, almost all of the carbon stored in the trees and vegetation called the aboveground carbon loss is lost. 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. There is a marked divide in the state of the worlds forests. Shifting agriculture is usually classified as degradation because the land is often abandoned and the forests regrow naturally. How Many Trees are Cut down for Paper Each Year . In the map we see their assessment of each countrys stage in the transition. 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 course and drivers of the forest transition: the case of France. The bar chart just below shows the earths surface cover just after the end of the last ice age.3 10,000 years ago 57% of the worlds habitable land was covered by forest. Many people think of environmental concerns as a modern issue: humanitys destruction of nature and ecosystems as a result of very recent population growth and increasing consumption. There is a geographical argument (why the tropics?) Healthy communities: Tree-filled neighborhoods lower levels of domestic violence and are safer and more sociable. If you struggle to increase crop yields but want to produce more food, then expanding your agricultural land is the only option. How many trees are lost to deforestation each year? 14% of deforestation is driven by consumers in the worlds richest countries we import beef, vegetable oils, cocoa, coffee and paper that has been produced on deforested land.12. The taller the bar, the larger the change in forest area. But the solution is not so simple. How many trees are cut down each year?. According to the Environmental Paper Network, an estimated 30% of felled trees are used for paper products. (2020). And its not just in forests eitherits also happening on farms, in cities, and on private property. Over half of the worlds species reside in tropical forests.24 Endemic species are those which only naturally occur in a single country. Tree density in primary forests varies from 50,000-100,000 trees per square km, so the math would put this number at 3.5 billion to 7 billion trees cut down each year. Deforestation in Africa is mainly driven by local populations and markets; only 9% of its emissions are exported. This is nearly always true of planted forests in temperate regions there, planted forests are long-established and do not replace primary existing forests. But distilling changes to this single metric tree or forest loss comes with its own issues. How many trees does IKEA cut down a Environmental impacts of food consumption in Europe. Nature, 525(7568), 201-205. Deforestation, reforestation, and development. As mentioned above, about 15 billion trees are cut down each year. Deforestation tends to occur on forests that have been around for centuries, if not millennia. 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). As mentioned above, about 15 billion trees are cut down each year. But when forests are cut, burned or otherwise removed they emit carbon instead of absorb carbon. It was predominantly temperate forests that were being lost at this time. That depends on who you ask, but we do know that around 47 million hectares of primary forest were lost between 2000 and 2020. Some interesting facts state that every second, 1.5 acres of wood are cut down, That depends on who you ask, but we do know that around 47 million hectares of primary forest were lost between 2000 and 2020. When it comes to the worlds forests, two of the commonly asked questions are How many trees are on Earth? and How many trees are cut down each year? In a previous post we looked at this change in global forests over the long-run. Since international demand is driving one-third of deforestation emissions, we have some opportunity to reduce emissions through global consumers and supply chains. 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.) In their analysis of global forest loss, Philip Curtis and colleagues used satellite images to assess where and why the world lost forests between 2001 and 2015. The average across the EU was 0.3 tonnes CO2 per person. Tropical forests are also large carbon sinks, and can store a lot of carbon per unit area.26. Forestry production and wildfires usually result in forest degradation the forest experiences short-term disturbance but if left alone is likely to regrow. FAO. But, understanding the role of deforestation in the products we buy is important. But when forests are cut, burned or otherwise removed they emit carbon instead of absorb carbon. Environmental Research Letters, 14(5), 055003. We see this in the chart. What explains this? Growing all those trees requires about 19.7 square miles of land. are added every year. International trade is important for socioeconomic development. Approximately 3.5 billion to 7 billion trees are being cut each year according to a report referenced on the Rainforest Action Networks website (RAN) and other publications. To understand this more recent loss of forest, lets zoom in on the last 300 years. 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. Decisionmakers could give as much of our attention to European logging as to destruction of the Amazon. Lewis, S. L., Edwards, D. P., & Galbraith, D. (2015). The total cut down so far is over 470 million trees since January 1st. How many trees are cut down each year in the Amazon rainforest? People cut down 15 billion trees each year and the global tree count has fallen by 46% since the beginning of human civilization. International trade was responsible for around one-third (29%) of these emissions. Since 2016, an average of 28 million hectares have been cut down every year. Habitat loss is the leading driver of global biodiversity loss.25 When we cut down rainforests we are destroying the habitats of many unique species, and reshaping these ecosystems permanently. Across sub-tropical countries we have a mix: many upper-middle income countries are now in the late transition phase. The total cut down so far is over 470 million trees since January 1st. How many trees have been cut down? When we think of the growing pressures on land from modern populations we often picture sprawling megacities. We know where deforestation emissions are occurring, and where this demand is coming from. It assumes the impact of clearing primary rainforest in the Amazon to produce soybeans is the same as logging planted forests in the UK. It provides long-term estimates on forest cover in 10,000 and 5,000 years BP. Global deforestation peaked in the 1980s. All the software and code that we write is open source and made available via GitHub under the permissive MIT license. They are smaller, and more temporary. Many farmers rely on international buyers to earn a living and improve their livelihoods. But forest cover increases through reforestation. For example, the average German generated half a tonne (510 kilograms) of CO2 per person from domestic and imported foods. Only 10% of this was lost in the first half of this period, until 5,000 years ago. Africa is also an outlier as a result of how many people still rely on wood as their primary energy source. How Many Trees are Cut down for Paper Each Year . We see one such transition in the chart: the forest loss in the temperate regions shown as the green part of the bars peaked much earlier than the global forest loss. How many trees does IKEA cut down a Loss of Biodiversity: Forests are the only liveable habitat for a variety of species around the globe many of which have not even have been discovered. Loss of Biodiversity: Forests are the only liveable habitat for a variety of species around the globe many of which have not even have been discovered. 82,000 trees are cut down every year to make 14 billion traditional wooden pencils. Brazils emissions are high because Brazilians eat a lot of beef. 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. Biodiversity: The ravages of guns, nets and bulldozers. Healthy communities: Tree-filled neighborhoods lower levels of domestic violence and are safer and more sociable. Lets now focus on the consumers of products driving deforestation. Africa is also different here. A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion. Weve seen the five key drivers of forest loss. 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. What are the major impacts of mass deforestation and forest loss? and an argument for why deforestation is worse than degradation. Data on net forest change, afforestation and deforestation is sourced from the UN Food and Agriculture Organizations Forest Resources Assessment. After we adjust for imports and exports, how much CO2 from deforestation is each country responsible for? 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. This interactive map shows deforestation rates across the world. In Latin America and Asia the dominant driver of degradation was logging for products such as timber, paper and pulp this accounted for more than 70%. [1] That's 15.3 billion every year. Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. Stage 3 The Late Transition phase is when deforestation rates start to slow down again. Thats both an economic and environmental win. University of Chicago Press.FAO (2020). People cut down 15 billion trees each year and the global tree count has fallen by 46% since the beginning of human civilization. Net forest loss is not the same as deforestation it measures deforestation plus any gains in forest over a given period. WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. 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.) 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%. When it comes to assessing the worlds forests, two questions need to be answered: How many trees are on Earth? and. 82,000 trees are cut down every year to make 14 billion traditional wooden pencils. And, we might place more value on preserving primary, native forests that havent yet been deforested over regrowing forests that have lost their previous ecosystems. Clearing of the Brazilian Amazon for pasture and croplands was a major driver of this loss. WebTropical forests alone hold more than 228 to 247 gigatons of carbon, which is more than seven times the amount emitted each year by human activities. They also contribute to global deforestation through the foods they import from poorer countries. To do this, they quantified where deforestation was occurring due to the expansion of croplands, pasture and tree plantations (for logging), and what commodities were produced on this converted land. The world has lost one-third of its forests, but an end of deforestation is possible. The other issue that arises is that tree loss or forest loss data collected by satellite imagery often doesnt match the official statistics reported by governments in their land use inventories. We should not only look at where these foods are produced, but also where the consumer demand is coming from. How much deforestation happens every day? The State of the Worlds Forests 2020. There is some bad news, though: that number is likely to increase by 20% by 2023. Luxembourg has the largest footprint at nearly three tonnes per person. How much deforestation happens every day? As we will see later, this would be a distraction from our primary concern: ending tropical deforestation. This number comes from the World Bank, which estimates that there are 3 trillion trees on the planet. A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion. That was 6.5% of global CO2 emissions.35. After seeing this data, people might argue that we should cut back on trade. The data used in this chart comes from several sources. In the article we will look at the reasons we lose forest; how these can be differentiated in a useful way; and what this means for understanding our priorities in tackling forest loss. How many trees are lost to deforestation each year? But then the trend turned, and it moved from deforestation to reforestation. Scientific Reports, 7, 40678. On the left-hand side we have the countries (grouped by region) where deforestation occurs, and on the right we have the countries and regions where these products are consumed. By Georgina Rannard. Humans have already destroyed around 46% of the trees on Earth. The default is shown for Brazil, but you can explore the data for a range of countries using the Change country button. 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.) The amount of land per person that was needed to produce enough food was not small in fact, it was much larger than today. The researchs results are Nature Sustainability, 1-9. 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 Earth System (Vol. 38. The world loses almost six million hectares of forest each year to deforestation. 38. This might paint a bleak picture for the future of the worlds forests: the United Nations projects that the global population will continue to grow, reaching 10.8 billion by 2100. Philosophical Transactions of the Royal Society B: Biological Sciences, 361(1465), 195-210. How many trees have been cut down? The 11-month balance shows that 1,539,970 trees were cut down each day, which means 1,059 trees per minute or almost 18 trees per second. That means that each year, one percent of all trees are being destroyed. International trade plays an important role in this growth, and may allow farmers to see the yield gains they need to produce more food using less land. This helps consumers understand what products they should be concerned about, but also allows us to target specific supply chains. The biodiversity of managed tree plantations which are periodically cut, regrown, cut again, then regrown is not the same. 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. An assessment of deforestation and forest degradation drivers in developing countries. Estimates vary, but most date the end of the last great ice age to around 11,700 years ago.Kump, L. R., Kasting, J. F., & Crane, R. G. (2004). Lets take an example. A note on UN FAO forestry data Data on net forest change, afforestation and deforestation is sourced from the UN Food and Agriculture Organizations Forest Resources Assessment. How much forest has the world lost? (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. How many trees are chopped down for Christmas? A future with more people and more forest is possible. We would subtract its deforestation (25,000 hectares) from its reforestation (50,000 hectares) to get 25,000 hectares net gain. In the chart we see deforestation emissions per person, measured in tonnes of CO2 per year. Rudel, T. K., Coomes, O. T., Moran, E., Achard, F., Angelsen, A., Xu, J., & Lambin, E. (2005). Why? It might seem odd to argue that we should focus our efforts on tackling this quarter of forest loss (rather than the other 73%). The scale of deforestation today might give us little hope for protecting our diverse forests. 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. Rome. Environmental Research Letters, 7(4), 044009. In the coming decades this is where we might expect to see the most rapid loss of forests unless these countries take action to prevent it, and the world supports them in the goal.
