how many trees are cut down each year

The diet of the average Brazilian creates 2.7 tonnes of CO2 from deforestation alone. This number comes from the World Bank, which estimates that there are 3 trillion trees on the planet. But, supply chains are international. Healthy environment: One hundred mature trees catch about 139,000 gallons of rainwater per year. All the software and code that we write is open source and made available via GitHub under the permissive MIT license. Journal of Rural Studies, 15(1), 65-90.Mather, A. S., & Needle, C. L. (2000). We therefore look at them both individually in more detail, to better understand what we can do about it. How many trees are lost to deforestation each year? The taller the bar, the larger the change in forest area. Which countries are gaining, and which are losing forest? Stage 2 The Early Transition phase is when countries start to lose forests very rapidly. Half of global forest loss occurred between 8,000BC and 1900; the other half was lost in the last century alone. Improvements in crop yields mean the per capita demand for agricultural land continues to fall. In 2012 the mid-year of this period global emissions from fossil fuels, industry and land use change was 40.2 billion tonnes. If we can take advantage of these innovations, we can bring deforestation to an end. 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. Each year, an estimated 15 billion trees are cut down around the world. WebThe UN FAO estimate that 10 million hectares of forest were cut down each year. Global Environmental Change, 56, 1-10. The rate of deforestation is declining, but we still lost forests at a whopping 10 million hectares per year between 2015-2020. Land, 9(5), 129. We then get high-income countries share of deforestation as: [40% of the 29% that is traded], which is equal to 12%. Philosophical Transactions of the Royal Society B: Biological Sciences, 361(1465), 195-210. Africas emissions are high because people are clearing forests to produce more food. The scale of deforestation today might give us little hope for protecting our diverse forests. How Many Trees are Cut down for Paper Each Year . What are the major impacts of mass deforestation and forest loss? 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). 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). [4] Forests cover 4.06 billion hectares (just less than 31%) of A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion. (2017). 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%). 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. How many trees are chopped down for Christmas? If poorer countries are cutting down forests to make food for rich consumers, then we should just stop trading these goods. Rome. As of 2020, the UN estimates the planet is losing over 7,000,000 hectares per year to deforestation.27Between 1990 and 2015, the world lost 129 million hectares of forest an area about the size of South Africa.11 Natural forests lost by continent9include: Africa 3.2 million hectares The definition of forest can vary depending on aspects such as tree density and height. The breakdown of deforestation by region is shown in the chart. Most emissions 71% came from foods consumed in the country that they were produced. Across sub-tropical countries we have a mix: many upper-middle income countries are now in the late transition phase. Tropical forests are home to some of the richest and most diverse ecosystems on the planet. In the map we see their assessment of each countrys stage in the transition. People cut down 15 billion trees each year and the global tree count has fallen by 46% since the beginning of human civilization. Thats both an economic and environmental win. Countries may lose some forest each year, but this is at a very slow rate. The research says 15.3 billion trees are chopped down every year. Then things started to speed up. Science, 349(6250), 827-832. Because people are starting to see how climate change affects trees. How many trees are cut down each year in the Amazon rainforest? 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. What activities are driving this? 71% of deforestation is for domestic production. From the chart we see that this was driven by the continued expansion of land for agriculture. Thats a lot of trees! We can calculate this increase as [(7.63 billion 3.09 billion) / 3.09 billion * 100 = 147%]. We need to pass the transition point as soon as possible, while minimising the amount of forest we lose along the way. Deforestation also results in larger losses of biodiversity and carbon relative to degradation. One of the reasons poorer countries clear forest to make room for farmland is that they achieve low crop yields. 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. Countries which lie above the grey line such as the United States, Finland, China restore more forest each year domestically than they import from elsewhere. Cuaresma, J. C., Danylo, O., Fritz, S., McCallum, I., Obersteiner, M., See, L., & Walsh, B. 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. To investigate this question, researchers Florence Pendrill et al. But the solution is not so simple. 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 number of trees cut down in the Brazilian Amazon in January far exceeded deforestation for the same month last year, according to government satellite data. Global Environmental Change, 15(1), 23-31. That means that each year, one percent of all trees are being destroyed. But when forests are cut, burned or otherwise removed they emit carbon instead of absorb carbon. This means they were responsible for 12% of global deforestation.31 It is therefore true that rich countries are causing deforestation in poorer countries. Americans cut down 15,094,678 Christmas trees in 2017, according to the most recent year of data from the U.S. Agriculture Department. https://doi.org/10.4060/ca8753en. We will always indicate the original source of the data in our documentation, so you should always check the license of any such third-party data before use and redistribution. The turn of the 20th century is when global forest loss reached the halfway point: half of total forest loss occurred from 8,000BC to 1900; the other half occurred in the last century alone. 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. 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). The UK imported 34,000 hectares of deforestation but increased its domestic forests by only 19,000 hectares. (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 beginning of this phase, the forest area is at its lowest point. Do rich countries import deforestation from overseas? The study also finds that human activity negatively affects tree abundance from the boreal forests to the equator. Tropical forests and the changing earth system. The UN FAO estimate that 10 million hectares of forest were cut down each year. The researchs results are That depends on who you ask, but we do know that around 47 million hectares of primary forest were lost between 2000 and 2020. Agricultural and forestry trade drives large share of tropical deforestation emissions. For the past 30 years, temperate regions have seen a continued increase in forest cover through afforestation: you see this as the bars are now positive (pointing upwards). Because people are starting to see how climate change affects trees. Humans have already destroyed around 46% of the trees on Earth. What are the major impacts of mass deforestation and forest loss? 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. Lets now focus on the consumers of products driving deforestation. In the chart we see how emissions from tropical deforestation are distributed through international supply chains. 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. Healthy communities: Tree-filled neighborhoods lower levels of domestic violence and are safer and more sociable. 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. Globally we deforest around ten million hectares of forest every year.11 Thats an area the size of Portugal every year. But international markets alone cannot fix this problem. Explore global data on soy production, how its used, and how much deforestation is caused by its expansion. WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. Global deforestation peaked in the 1980s. In contrast, most forest degradation two-thirds of it occurs in temperate countries. 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. How many trees have been cut down? Deforesting the earth: from prehistory to global crisis. 79% of exported deforestation ended up in those countries that had stopped losing domestic forests. Countries below the line such as the UK and Germany are not growing forests fast enough to offset the deforestation theyre creating elsewhere. Pre-1961 land use is sourced from the work of Ellis et al. Decisionmakers could give as much of our attention to European logging as to destruction of the Amazon. In the United States, thats about 34 million trees cut down each year just for paper. 95% of the worlds deforestation occurs in the tropics [we look at this breakdown again later]. In the map we see the net deforestation embedded in trade for each country. Many farmers rely on international buyers to earn a living and improve their livelihoods. This interactive map shows deforestation rates across the world. Rudel, T. K. (1998). The rate of deforestation is declining, but we still lost forests at a whopping 10 million hectares per year between 2015-2020. After we adjust for imports and exports, how much CO2 from deforestation is each country responsible for? One option is to adopt stricter guidelines on what suppliers to source from, and implementing zero-deforestation policies that stop the trade of goods that have been produced on deforested land. Global forest resources. They should keep their domestic reforestation targets in perspective with their net impact on global forests. This is because the latter only captures deforestation the replacement of forest with another land use (such as cropland). Rather than looking at total figures by country [if youre interested, we have mapped them here] we have calculated the per capita footprint. Can we bring it to an end? When citing this topic page, please also cite the underlying data sources. Humans have already destroyed around 46% of the trees on Earth. Degradation drivers, including logging and especially wildfires can definitely have major impacts on forest health: animal populations decline, trees can die, and CO2 is emitted. As we saw previously, this deforestation accounts for around one-quarter of global forest loss. Geographical Journal, 166(1), 2-13. At the top of the list we see some of the major producer countries Brazil and Indonesia. Note that in this study, the category of subsistence agriculture was classified as a deforestation driver, and so is not included. 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. That means that each year, one percent of all trees are being destroyed. Absolute estimates of forest cover from other sources may differ for this reason. Rural Sociology, 63(4), 533-552. Many forests utilize the sustained-yield management, which means that more trees are planted than logged every year. Rome. How many trees are cut down each year? 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%. It was predominantly temperate forests that were being lost at this time. This gives us an indication of the impact of the average persons diet. Mather, A. S., Fairbairn, J., & Needle, C. L. (1999). The global population at this time was small and growing very slowly there were fewer than 50 million people in the world.
