how many trees are cut down each year

The study also finds that human activity negatively affects tree abundance from the boreal forests to the equator. 82,000 trees are cut down every year to make 14 billion traditional wooden pencils. 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? The UK imported 34,000 hectares of deforestation but increased its domestic forests by only 19,000 hectares. The first step in doing this is for rich countries to monitor their deforestation impacts overseas more closely. But there is good reason to make this our primary concern. Nature, 525(7568), 201-205. What explains this? Deforestation, reforestation, and development. Curtis, P. G., Slay, C. M., Harris, N. L., Tyukavina, A., & Hansen, M. C. (2018). This is probably less than many people would expect. Because people are starting to see how climate change affects trees. 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. How many trees are cut down each year?. Hosonuma, N., Herold, M., De Sy, V., De Fries, R. S., Brockhaus, M., Verchot, L., & Romijn, E. (2012). Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. Environmental Research Letters, 7(4), 044009. If we want to end deforestation we need to understand where and why its happening; where countries are within their transition; and what can be done to accelerate their progress through it. The research says 15.3 billion trees are chopped down every year. Nature Sustainability, 1-9. How Many Acres of Trees Are Cut Down Each Year? [4] Forests cover 4.06 billion hectares (just less than 31%) of After long periods of forest clearance in the past, most of todays richest countries are increasing tree cover through afforestation. The relationships of population and forest trends. In the chart here we see the breakdown of deforestation emissions by product for each consumer country. Africas emissions are high because people are clearing forests to produce more food. Science, 361(6407), 1108-1111. Across sub-tropical countries we have a mix: many upper-middle income countries are now in the late transition phase. As I mentioned earlier, 14% of deforestation today is driven by consumers in rich countries. On the horizontal axis we have time, spanning from 1700 to 2020; on the vertical axis we have the decadal change in forest cover. Deforestation is the complete removal of trees for the conversion of forest to another land use such as agriculture, mining, or towns and cities. Thats like losing an area the size of Portugal every two years. Because people are starting to see how climate change affects trees. 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. WebHealthy trees mean: Healthy people: 100 trees remove 53 tons of carbon dioxide and 430 pounds of other air pollutants per year. The amount of land per person that was needed to produce enough food was not small in fact, it was much larger than today. 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%. 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. Philosophical Transactions of the Royal Society B: Biological Sciences, 361(1465), 195-210. 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. An assessment of deforestation and forest degradation drivers in developing countries. FAO. 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%. This interactive map shows deforestation rates across the world. 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. In 2012 the mid-year of this period global emissions from fossil fuels, industry and land use change was 40.2 billion tonnes. How many trees are cut down each year in the Amazon rainforest? University of Chicago Press.FAO (2020). Notarnicola et al. Growing all those trees requires about 19.7 square miles of land. We see massive differences in how important each driver is across the world. This interactive map shows deforestation rates across the world. Population growth meant that todays rich countries across Europe and North America needed more and more resources such as land for agriculture, wood for energy, and for construction.8. This interactive map shows deforestation rates across the world. But it can bridge between deforestation and degradation depending on the timeframe and permanence of these agricultural practices. Imported emissions are also high for Taiwan, Belgium and the Netherlands at around one tonne. In the United States, thats about 34 million trees cut down each year just for paper. From 1850 to 1920, losses were around 50% higher at 30 million hectares per decade thats like losing a forested area the size of Italy every 10 years. 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%. Is there a forest transition? 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. They are smaller, and more temporary. Mather refers to an annual loss of less than 0.25% as a small loss. In a related article we look in much more detail at what agricultural products, and which countries are driving this. 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. I have reconstructed long-term data using various studies which Ive documented here. It assumes the impact of clearing primary rainforest in the Amazon to produce soybeans is the same as logging planted forests in the UK. Today thats just 34%. Global deforestation peaked in the 1980s. Historical data pre-1990 is sourced from Michael Williams book, Deforesting the Earth: from prehistory to global crisis. 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. Lets now focus on the consumers of products driving deforestation. Our crop yields improve and so we need less land for agriculture. When we cut down primary rainforest we are transforming this ecosystem forever. Many consumers are concerned that their food choices are linked to deforestation in some of these hotspots. Since 2016, an average of 28 million hectares have been cut down every year. People cut down 15 billion trees each year and the global tree count has fallen by 46% since the beginning of human civilization. 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. But, supply chains are international. From the chart we see that this was driven by the continued expansion of land for agriculture. Environmental impacts of food consumption in Europe. According to the Environmental Paper Network, an estimated 30% of felled trees are used for paper products. Because people are starting to see how climate change affects trees. How many trees does IKEA cut down a It would be good if there was data available that would capture these additional aspects. This means interventions at the national-level will be key: this can include a range of solutions including policies such as Brazils soy moratorium, the REDD+ programme to compensate for the opportunity costs of preserving these forests, and improvements in agricultural productivity so countries can continue to produce more food on less land. We then get high-income countries share of deforestation as: [40% of the 29% that is traded], which is equal to 12%. 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. The fact that the per capita emissions after trade are very high means that a lot of their food products are consumed by people in Brazil and Indonesia. 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. But, understanding the role of deforestation in the products we buy is important. How many trees does IKEA cut down a The amount of land used for agriculture land to grow crops as well as grazing land for livestock was expanding. Cutting them down disrupts or destroys established, species-rich ecosystems. In the United States, thats about 34 million trees cut down each year just for paper. Deforestation also results in larger losses of biodiversity and carbon relative to degradation. Since 2016, an average of 28 million hectares have been cut down every year. 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. Lets take an example. Absolute estimates of forest cover from other sources may differ for this reason. Growing all those trees requires about 19.7 square miles of land. Then things started to speed up. The researchs results are 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. 71% of this is driven by demand in domestic markets, and the remaining 29% for the production of products that are traded. The paths between these end boxes indicate where emissions are being traded the wider the bar, the more emissions are embedded in these products. Healthy environment: One hundred mature trees catch about 139,000 gallons of rainwater per year. Lewis, S. L., Edwards, D. P., & Galbraith, D. (2015). Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. In the chart we see how emissions from tropical deforestation are distributed through international supply chains. They are also richer sites of biodiversity. Science, 349(6250), 827-832.Williams, D. R., Clark, M., Buchanan, G. M., Ficetola, G. F., Rondinini, C., & Tilman, D. (2020). Forests are mainly cut and burned to make space for local, subsistence agriculture or for fuelwood for energy. Deforestation in Africa is mainly driven by local populations and markets; only 9% of its emissions are exported. Sometimes these restoration programmes pale in comparison to the deforestation theyre driving elsewhere. Imagine over 100 large harvesters working non-stop. Most tropical deforestation is driven by demand for products in domestic markets. Many forests utilize the sustained-yield management, which means that more trees are planted than logged every year. As we will see later, this is dominated by palm oil exports to Europe, China, India, North America and the Middle East. How many trees have been cut down? The same is true of the United States; back in 1630 46% of the area of todays USA was covered by forest. How Many Trees are Cut down for Paper Each Year . (2012) gathered this data from a range of sources including country submissions as part of their REDD+ readiness activities, Center for International Forestry Research (CIFOR) country profiles, UNFCCC national communications and scientific studies. There is little forest left. But we also need to know what products are driving this. If you want to reduce your carbon footprint, reducing meat and dairy intake particularly beef and lamb has the largest impact. By the 19th century the forest area was reduced to a third of what it once was. This number comes from the World Bank, which estimates that there are 3 trillion trees on the planet. In the map we see the net deforestation embedded in trade for each country. In the chart we see historical reconstructions of country-level data on the share of land covered by forest (over decades, centuries or even millennia depending on the country). Mapping tree density at a global scale. These are big numbers, and important ones to track: forest loss creates a number of negative impacts, ranging from carbon emissions to species extinctions and biodiversity loss. Decisionmakers could give as much of our attention to European logging as to destruction of the Amazon. Across temperate forests the world gained 6 million hectares in the last decade. Why should we care most about tropical deforestation? 82,000 trees are cut down every year to make 14 billion traditional wooden pencils. 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. For the last two centuries forests have been growing and are almost back to where they were 1000 years ago.13. Nature, 536(7615), 143. This gives us an indication of the impact of the average persons diet. How Many Trees are Cut down for Paper Each Year . Since 2016, an average of 28 million hectares have been cut down every year. If you struggle to increase crop yields but want to produce more food, then expanding your agricultural land is the only option. [4] Forests cover 4.06 billion hectares (just less than 31%) of Rich countries such as the USA, France and the United Kingdom have had a long history of deforestation but are now passed the transition point. But a small global population overall meant there was little pressure on forests to make space for land to grow food, and as wood for energy. Some interesting facts state that every second, 1.5 acres of wood are cut down, Many farmers rely on international buyers to earn a living and improve their livelihoods. 95% of this occurs in the tropics. Classifying drivers of global forest loss. As to the number of trees this represents, its impossible to get an accurate count. But we also see that some countries which import a lot of food have high emissions. 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. (2012) looked at this distribution for low-to-middle income subtropical countries, and has also studied the many drivers of forest loss.Hosonuma, N., Herold, M., De Sy, V., De Fries, R. S., Brockhaus, M., Verchot, L., & Romijn, E. (2012). But it was then that England reached its transition point and since then, forests have doubled in size. The total cut down so far is over 470 million trees since January 1st. Countries with a positive change (shown in green) are regrowing forest faster than theyre losing it. The research says 15.3 billion trees are chopped down every year. Web3.5 billion to 7 billion trees are cut down per year. Thats an area the size of the United Kingdom. 40% of traded deforestation ends up in high-income countries, meaning they are responsible for 12% of deforestation.29. 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. The remaining 73% came from the three drivers of forest degradation: logging of forestry products from plantations (26%); shifting, local agriculture (24%); and wildfires (23%). That means that each year, one percent of all trees are being destroyed. Upper Saddle River, NJ: Pearson Prentice Hall. Tyukavina, A., Hansen, M. C., Potapov, P. V., Stehman, S. V., Smith-Rodriguez, K., Okpa, C., & Aguilar, R. (2017). But there are real reasons to believe that this century doesnt have to replicate the destruction of the last one. 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. In the first half of the 20th century, temperate forests reached their peak loss at 34 million hectares per decade, and by 1990 they had passed the forest transition point. Forest loss or tree loss captures two fundamental impacts on forest cover: deforestation and forest degradation. Forestry production and wildfires usually result in forest degradation the forest experiences short-term disturbance but if left alone is likely to regrow. Stage 4 The Post-Transition phase is when countries have passed the transition point and are now gaining forest again. Nearly half (47%) of France was forested 1000 years ago; today thats just under one-third (31.4%). 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. We need to pass the transition point as soon as possible, while minimising the amount of forest we lose along the way. 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.) Brazil and Indonesia alone account for almost half. Since international demand is driving one-third of deforestation emissions, we have some opportunity to reduce emissions through global consumers and supply chains. Most of todays richest countries all of Europe, North America, Japan, South Korea have passed the turning point and are now regaining forest. We know where deforestation emissions are occurring, and where this demand is coming from. Then things started to speed up. Low agricultural productivity and a reliance on wood for fuel meant that large amounts of land had to be cleared for basic provisions. Half of global forest loss occurred between 8,000BC and 1900; the other half was lost in the last century alone. Today, most deforestation occurs in the tropics. We can illustrate this through the so-called Forest Transition Model.14 This is shown in the chart. Rural Sociology, 63(4), 533-552. How many trees are lost to deforestation each year? [2] Only 36% of the world's rainforests remain intact. However, most align on the relative change in forests over this period. In a previous post we looked at this change in global forests over the long-run. 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. We manage to capture some of these differences in carbon in our related article on deforestation emissions embedded in trade. 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. 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. (2020). By Georgina Rannard. But the solution is not so simple. (2017). The Earth System (Vol. How many trees are cut down each year? are added every year. The world loses 5 million hectares of forest to deforestation each year. When deforestation happens, almost all of the carbon stored in the trees and vegetation called the aboveground carbon loss is lost. How many trees are cut down each year in the Amazon rainforest? The research says 15.3 billion trees are chopped down every year. As mentioned above, about 15 billion trees are cut down each year. Many countries have followed this classic U-shaped pattern. A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion.
