how many trees are cut down each year

We know where deforestation emissions are occurring, and where this demand is coming from. Within this global aggregated trend there are many forest transitions at local, national or regional levels occurring. theyre driving deforestation elsewhere; whilst many subtropical countries are partly cutting down trees to meet this demand from rich countries. Global deforestation peaked in the 1980s. Scheffers, B. R., Joppa, L. N., Pimm, S. L., & Laurance, W. F. (2012). WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. How many trees are chopped down for Christmas? How many trees are cut down each year? 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. It was a net exporter. As we will see later, this would be a distraction from our primary concern: ending tropical deforestation. [2] Only 36% of the world's rainforests remain intact. Science, 349(6250), 827-832.Williams, D. R., Clark, M., Buchanan, G. M., Ficetola, G. F., Rondinini, C., & Tilman, D. (2020). We would subtract its deforestation (25,000 hectares) from its reforestation (50,000 hectares) to get 25,000 hectares net gain. However, most align on the relative change in forests over this period. This often comes at the cost of forests. We manage to capture some of these differences in carbon in our related article on deforestation emissions embedded in trade. After seeing this data, people might argue that we should cut back on trade. On the x-axis we have imported deforestation. Americans cut down 15,094,678 Christmas trees in 2017, according to the most recent year of data from the U.S. Agriculture Department. Luxembourg has the largest footprint at nearly three tonnes per person. Since international demand is driving one-third of deforestation emissions, we have some opportunity to reduce emissions through global consumers and supply chains. Agricultural and forestry trade drives large share of tropical deforestation emissions. 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. International trade is important for socioeconomic development. A new study published in Nature estimates the planet has 3.04 trillion trees. There is a marked divide in the state of the worlds forests. [1] That's 15.3 billion every year. Its State of the Worlds Forests report provides estimates of global forest cover today, and rates of change over previous decades. Global Environmental Change, 56, 1-10. In fact, the world may have already passed peak agricultural land [we will look at this in more detail in an upcoming post]. As we will see later, this is dominated by palm oil exports to Europe, China, India, North America and the Middle East. 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. 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. Noriko Hosonuma et al. What activities are driving this? Today, only 4 billion hectares are left. Crowther, T. W., Glick, H. B., Covey, K. R., Bettigole, C., Maynard, D. S., Thomas, S. M., & Tuanmu, M. N. (2015). It also estimates that 46% of the worlds trees have been cleared over the past 12,000 years. 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). Journal of Rural Studies, 15(1), 65-90.Mather, A. S., & Needle, C. L. (2000). The rate of deforestation is declining, but we still lost forests at a whopping 10 million hectares per year between 2015-2020. England is similar: in the late 11th century, 15% of the country was forested, and over the following centuries two-thirds were cut down. This increase was mostly driven by tropical deforestation as countries across Asia and Latin America followed the path of Europe and North America. Countries may lose some forest each year, but this is at a very slow rate. Nearly half (47%) of France was forested 1000 years ago; today thats just under one-third (31.4%). 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. Forests are mainly cut and burned to make space for local, subsistence agriculture or for fuelwood for energy. Note that this only measures the emissions from tropical deforestation it doesnt include any other emissions from agricultural production, such as methane from livestock, or rice, or the use of fertilizers. 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. Year-to-year data on forest change comes with several issues: either data at this resolution is not available, or year-to-year changes can be highly variable. University of Chicago Press. But most emissions are driven by domestic markets this means policies in the major producer countries will be key to tackling this problem. Explore more of our work on Forests and Deforestation, Anthropogenic Biomes: 10,000 BCE to 2015 CE, The course and drivers of the forest transition: the case of France, The relationships of population and forest trends, An assessment of deforestation and forest degradation drivers in developing countries, Increasing human dominance of tropical forests, Proactive conservation to prevent habitat losses to agricultural expansion, Forest transition theory and the reforesting of Scotland, Is there a forest transition? Forests still cover about 30 percent of the worlds land area, but they are disappearing at an alarming rate. 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]. 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. A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion. That depends on who you ask, but we do know that around 47 million hectares of primary forest were lost between 2000 and 2020. You have permission to use, distribute, and reproduce these in any medium, provided the source and authors are credited. The change is temporary. Deforestation and forest degradation are responsible for around 15% of all greenhouse gas 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). Since 2016, an average of 28 million hectares have been cut down every year. Africa is also an outlier as a result of how many people still rely on wood as their primary energy source. Forest loss measures the net change in forest cover: the loss in forests due to deforestation plus any expansion of forest through afforestation.6. Tropical forests, on aggregate, have also passed peak deforestation in the 1980s the longest of all bars but have not passed the transition to reforestation. How much deforestation happens every day? Brazil and Indonesia alone account for almost half. Brazils emissions are high because Brazilians eat a lot of beef. are added every year. The default is shown for Brazil, but you can explore the data for a range of countries using the Change country button. Web42 million trees are cut down each day. 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. Forests still cover about 30 percent of the worlds land area, but they are disappearing at an alarming rate. As we covered in a previous article, 60% of tropical deforestation is driven by beef, soybean and palm oil production. But, as countries continue to get richer this demand slows. The UN FAO estimate that 10 million hectares of forest were cut down each year. Humans have been cutting down trees for millennia. Since 2016, an average of 28 million hectares have been cut down every year. 95% of global deforestation occurs in the tropics. The United Nations, as well as experts at the World Wildlife Fund and Global Forest Watch, found that one million animals are in danger of extinction as a result of how much deforestation has occurred. Most tropical deforestation is driven by demand for products in domestic markets. This is calculated by taking each countrys imported deforestation and subtracting its exported deforestation. Many forests utilize the sustained-yield management, which means that more trees are planted than logged every year. Explore long-term changes in deforestation, and deforestation rates across the world today. The taller the bar, the larger the change in forest area. Global forest resources. WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. Why? 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. At the beginning of this phase, the forest area is at its lowest point. How many trees does IKEA cut down a Clearing of the Brazilian Amazon for pasture and croplands was a major driver of this loss. That these countries have recently regained forests is also visible in the long-term forest trends above. But, supply chains are international. Humans have already destroyed around 46% of the trees on Earth. People cut down 15 billion trees each year and the global tree count has fallen by 46% since the beginning of human civilization. All the software and code that we write is open source and made available via GitHub under the permissive MIT license. This map shows the net change in forest cover across the world. They cut down their forests and replaced it with agricultural land long ago. These countries might have high levels of afforestation at home, but theyre still having a net negative impact on the size of the worlds forests. But the magnitude of these impacts are often less than the complete conversion of forest. The breakdown of forest loss globally, and by region, is shown in the chart.22. Rural Sociology, 63(4), 533-552. But there are real reasons to believe that this century doesnt have to replicate the destruction of the last one. In China, the biggest driver is demand for oilseeds which is the combination of soy imported from Latin America and palm oil, imported from Indonesia and Malaysia. It would be good if there was data available that would capture these additional aspects. The world lost 1.5 billion hectares of forest over that period. 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%. Thats more than the countrys CO2 emissions from fossil fuels, which are around 2.2 tonnes per person. 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. Global deforestation reached its peak in the 1980s. The research says 15.3 billion trees are chopped down every year. And to identify where deforestation is occurring; perhaps as important, show where forest loss is not deforestation.
