how many trees are cut down each year

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. At the top of the list we see some of the major producer countries Brazil and Indonesia. We need to pass the transition point as soon as possible, while minimising the amount of forest we lose along the way. 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 But we should keep these important aspects in mind when comparing forest losses and gains. 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 Thats equivalent to the area of South Africa. The first step in doing this is for rich countries to monitor their deforestation impacts overseas more closely. What are the major impacts of mass deforestation and forest loss? 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. 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.) Each year, an estimated 15 billion trees are cut down around the world. Thats more than the countrys CO2 emissions from fossil fuels, which are around 2.2 tonnes per person. On the horizontal axis we have time, spanning from 1700 to 2020; on the vertical axis we have the decadal change in forest cover. Do rich countries import deforestation from overseas? Global deforestation reached its peak in the 1980s. 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. [2] Only 36% of the world's rainforests remain intact. Global Forest Resources Assessment 2020 Key findings. Forestry production and wildfires usually result in forest degradation the forest experiences short-term disturbance but if left alone is likely to regrow. Most of todays richest countries all of Europe, North America, Japan, South Korea have passed the turning point and are now regaining forest. 432). The State of the Worlds Forests 2020. Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. The rate of population growth tends to slow down. This is probably less than many people would expect. WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. 79% of exported deforestation ended up in those countries that had stopped losing domestic forests. The Asia-Pacific region predominantly Indonesia and Malaysia export a higher share: 44%. (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. How much forest has the world lost? Because people are starting to see how climate change affects trees. 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. 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. Because people are starting to see how climate change affects trees. Without reliable metrics that capture all of these differences, we will have to stick with total changes in forest area for now. This interactive map shows deforestation rates across the world. The researchs results are Shifting agriculture is usually classified as degradation because the land is often abandoned and the forests regrow naturally. Because people are starting to see how climate change affects trees. But this is no longer the case: forest loss across North America and Europe is now the result of harvesting forestry products from tree plantations, or tree loss in wildfires. It results in a permanent conversion of forest into an alternative land use. They are also richer sites of biodiversity. Nature, 525(7568), 201-205. To investigate this question, researchers Florence Pendrill et al. Nearly half (47%) of France was forested 1000 years ago; today thats just under one-third (31.4%). 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. And its not just in forests eitherits also happening on farms, in cities, and on private property. When in history did we lose it? Web3.5 billion to 7 billion trees are cut down per year. Carbon emissions from deforestation: are they driven by domestic demand or international trade? 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. Pendrill, F., Persson, U. M., Godar, J., & Kastner, T. (2019). Available here. The history of deforestation is a tragic one, in which we not only lost these wild and beautiful landscapes but also the wildlife within them. A new study published in Nature estimates the planet has 3.04 trillion trees. Nicolas-Jacques Cont, an officer in Napoleon's army, invented the modern pencil by combining graphite and clay for lead durability. 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. Tropical forests are often more productive than temperate forests, meaning they store more carbon. Tropical forests are also large carbon sinks, and can store a lot of carbon per unit area.26. 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. Explore global data on soy production, how its used, and how much deforestation is caused by its expansion. I have reconstructed long-term data using various studies which Ive documented here. 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. 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. Instead of using wood for fuel we switch to fossil fuels, or hopefully, more renewables and nuclear energy. Since then, deforestation rates have steadily declined, to 78 million hectares in the 1990s; 52 million in the early 2000s; and 47 million in the last decade. Environmental Research Letters, 7(4), 044009. This helps consumers understand what products they should be concerned about, but also allows us to target specific supply chains. Nature Sustainability, 1-9. But by studying how forests have changed over time, theres good reason to think that a way forward is possible. 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. Some interesting facts state that every second, 1.5 acres of wood are cut down, Centuries ago it was mainly temperate regions that were driving global deforestation [we take a look at this longer history of deforestation in a related article]. Many farmers rely on international buyers to earn a living and improve their livelihoods. What if this deforestation is being driven by consumers elsewhere? (2020). Forest transition theory and the reforesting of Scotland. Rudel, T. K. (1998). Deforesting the earth: from prehistory to global crisis. It was predominantly temperate forests that were being lost at this time. England is similar: in the late 11th century, 15% of the country was forested, and over the following centuries two-thirds were cut down. Thats one football field of forest lost every single second around the clock. Since international demand is driving one-third of deforestation emissions, we have some opportunity to reduce emissions through global consumers and supply chains. Geographical Journal, 166(1), 2-13. The breakdown of forest loss globally, and by region, is shown in the chart.22. Thats one football field of forest lost every single second around the clock. As to the number of trees this represents, its impossible to get an accurate count. It also estimates that 46% of the worlds trees have been cleared over the past 12,000 years. This number comes from the World Bank, which estimates that there are 3 trillion trees on the planet. 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. Growing all those trees requires about 19.7 square miles of land. Mapping tree density at a global scale. 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. Deforestation tends to occur on forests that have been around for centuries, if not millennia. There is some bad news, though: that number is likely to increase by 20% by 2023. Not all forest loss is equal: what is the difference between deforestation and forest degradation? Absolute estimates of forest cover from other sources may differ for this reason. According to CNN, each year over 1,000 plants and animal species go extinct due to deforestation and subsequent habitat loss. We see very clearly that the large Brazilian footprint is driven by its domestic demand for beef. Upper Saddle River, NJ: Pearson Prentice Hall. 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. 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. 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. But it was then that England reached its transition point and since then, forests have doubled in size. Africa is also different here. 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.) This emphasises two important points. We should not only look at where these foods are produced, but also where the consumer demand is coming from. In the tropics, some forestry production can be classified as deforestation when primary rainforests are cut down to make room for managed tree plantations.21. For the last two centuries forests have been growing and are almost back to where they were 1000 years ago.13. 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. That means that each year, one percent of all trees are being destroyed. Countries may lose some forest each year, but this is at a very slow rate. Thats a lot of trees! Its domestic demand, not international trade, that is the main driver of deforestation. Across the US and Europe the breakdown of products is more varied. 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). Each year, an estimated 15 billion trees are cut down around the world. How many trees are lost to deforestation each year? Global forest resources. Global deforestation peaked in the 1980s.
