how many trees are cut down each yearhow many trees are cut down each year

How many trees are chopped down for Christmas? Most tropical deforestation is driven by demand for products in domestic markets. How many trees are cut down each year in the Amazon rainforest? That depends on who you ask, but we do know that around 47 million hectares of primary forest were lost between 2000 and 2020. The world lost 1.5 billion hectares of forest over that period. International trade is important for socioeconomic development. Thats a lot of trees! Thats equivalent to the area of South Africa. This is because the latter only captures deforestation the replacement of forest with another land use (such as cropland). Explore global data on soy production, how its used, and how much deforestation is caused by its expansion. Brazil, for example, went through a period of very rapid deforestation in the 1980s and 90s (its early transition phase) but its losses have slowed, meaning it is now in the late transition. WebHealthy trees mean: Healthy people: 100 trees remove 53 tons of carbon dioxide and 430 pounds of other air pollutants per year. Most emissions 71% came from foods consumed in the country that they were produced. WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. Licenses: All visualizations, data, and articles produced by Our World in Data are open access under the Creative Commons BY license. But we also see that some countries which import a lot of food have high emissions. Countries may lose some forest each year, but this is at a very slow rate. What are the major impacts of mass deforestation and forest loss? First, it reiterates that deforestation is not a new problem: relatively small populations of the past were capable of driving a large amount of forest loss. The grey line marks where the area of domestic regrowth of forests is exactly equal to imported deforestation. Stage 4 The Post-Transition phase is when countries have passed the transition point and are now gaining forest again. That means that each year, one percent of all trees are being destroyed. Forest loss or tree loss captures two fundamental impacts on forest cover: deforestation and forest degradation. 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. Although there is some year-to-year variability [you can explore the data use the timeline on the bottom of the chart from 2005 to 2013] we see a reasonably consistent divide: most countries across Europe and North America are net importers of deforestation i.e. Nearly all 95% of this deforestation occurs in the tropics. Africas emissions are high because people are clearing forests to produce more food. 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. 71% of this is driven by demand in domestic markets, and the remaining 29% for the production of products that are traded. Healthy communities: Tree-filled neighborhoods lower levels of domestic violence and are safer and more sociable. The changes to the forest are often temporary and its expected that they will regrow. As to the number of trees this represents, its impossible to get an accurate count. In the chart we see the comparison between the change in domestic forest area, and deforestation driven by imported goods.33 On the vertical axis we have the domestic change in forest area: this is shown only for countries where the forest area is increasing. 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. What explains this? Do rich countries import deforestation from overseas? Sometimes these restoration programmes pale in comparison to the deforestation theyre driving elsewhere. This is probably less than many people would expect. How many trees does IKEA cut down a There are other aspects to consider. And its not just in forests eitherits also happening on farms, in cities, and on private property. The United States is the worlds largest consumer (and second largest producer, after Canada) of forest products. Since three-quarters of tropical deforestation is driven by agriculture, thats a valid concern. Thats an area 1.5-times the size of the United States. Rudel, T. K., Coomes, O. T., Moran, E., Achard, F., Angelsen, A., Xu, J., & Lambin, E. (2005). A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion. 95% of this occurs in the tropics. WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. How many trees are cut down each year? If we fast-forward to 1700 when the global population had increased more than ten-fold, to 603 million. The diet of the average Brazilian creates 2.7 tonnes of CO2 from deforestation alone. Bringing all of these elements together, we can focus on a few points that should help us prioritise our efforts to end deforestation. (2020). But they wanted to contribute to a more informed discussion about where to focus forest conservation efforts by understanding why forests were being lost. They first lose lots of forest, but reach a turning point and begin to regain it again. Which countries are gaining, and which are losing forest? In the chart we see how emissions from tropical deforestation are distributed through international supply chains. A new study published in Nature estimates the planet has 3.04 trillion trees. Science, 349(6250), 827-832. When we treat these impacts equally we make it difficult to prioritize our efforts in the fight against deforestation. It would be good if there was data available that would capture these additional aspects. To quote them, they wanted to prevent a common misperception that any tree cover loss shown on the map represents deforestation. And with the growth of technological innovations such as lab-grown meat and substitute products, there is the real possibility that we can continue to enjoy meat or meat-like foods while freeing up the massive amounts of land we use to raise livestock. The research says 15.3 billion trees are chopped down every year. 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. Thats one football field of forest lost every single second around the clock. The United States is the worlds largest consumer (and second largest producer, after Canada) of forest products. 1000 years ago, 20% of Scotlands land was covered by forest. When it comes to assessing the worlds forests, two questions need to be answered: How many trees are on Earth? and. Each year, an estimated 15 billion trees are cut down around the world. Global Forest Resources Assessment 2020: Main report. At their Global Forest Watch platform they were already presenting maps of forest loss across the world. Not only would this be bad for people, it might also be bad for forests. There is some bad news, though: that number is likely to increase by 20% by 2023. (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). An assessment of deforestation and forest degradation drivers in developing countries. 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. The study also finds that human activity negatively affects tree abundance from the boreal forests to the equator. Brazil, in contrast, caused more deforestation domestically in the production of goods for other countries than it imported from elsewhere. Lewis, S. L. (2006). 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. The United States is the worlds largest consumer (and second largest producer, after Canada) of forest products. We see massive differences in how important each driver is across the world. How many trees are cut down each year?. [4] Forests cover 4.06 billion hectares (just less than 31%) of Since 1961, the amount of land we use for agriculture increased by only 7%. Lewis, S. L., Edwards, D. P., & Galbraith, D. (2015). 38. Tropical forests are often more productive than temperate forests, meaning they store more carbon. If you struggle to increase crop yields but want to produce more food, then expanding your agricultural land is the only option. The Earth System (Vol. (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. At the end of this stage, countries are approaching the transition point. This shifting agriculture category can be difficult to allocate between deforestation and degradation: it often requires close monitoring over time to understand how permanent these agricultural practices are. On balance, they add to the global forest stock. As we saw previously, this deforestation accounts for around one-quarter of global forest loss. Web3.5 billion to 7 billion trees are cut down per year. Anthropogenic Biomes: 10,000 BCE to 2015 CE. 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. Global Environmental Change, 15(1), 23-31. Notarnicola et al. Net importers of deforestation (shown in brown) are countries that contribute more to deforestation in other countries than they do in their home country. (2010) looked at the primary drivers of deforestation and degradation across tropical and subtropical countries specifically.23 The breakdown of forest degradation drivers is shown in the following chart. In the chart here we see the breakdown of deforestation emissions by product for each consumer country. But the solution is not so simple. Over the decade since 2010, the net loss in forests globally was 4.7 million hectares per year.1 However, deforestation rates were much significantly higher.
