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. The world passed peaked deforestation in the 1980s and it has been on the decline since then we take a look at rates of forest loss since 1700 in our follow-up post. Lets now focus on the consumers of products driving deforestation. Countries may lose some forest each year, but this is at a very slow rate. That is why we should be focusing on tropical deforestation. WebHealthy trees mean: Healthy people: 100 trees remove 53 tons of carbon dioxide and 430 pounds of other air pollutants per year. How Many Trees are Cut down for Paper Each Year . Africas emissions are high because people are clearing forests to produce more food. Rudel, T. K. (1998). Healthy communities: Tree-filled neighborhoods lower levels of domestic violence and are safer and more sociable. This number comes from the World Bank, which estimates that there are 3 trillion trees on the planet. 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. National Inventory of Woodland and Trees, England (2001). This gives us an indication of the impact of the average persons diet. Deforestation is the complete removal of trees for the conversion of forest to another land use such as agriculture, mining, or towns and cities. Deforestation rates accelerated. Today, only 4 billion hectares are left. It also estimates that 46% of the worlds trees have been cleared over the past 12,000 years. As to the number of trees this represents, its impossible to get an accurate count. The total cut down so far is over 470 million trees since January 1st. There is some bad news, though: that number is likely to increase by 20% by 2023. There is a marked divide in the state of the worlds forests. 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.) 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). Humans have been cutting down trees for millennia. 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. [4] Forests cover 4.06 billion hectares (just less than 31%) of Within this global aggregated trend there are many forest transitions at local, national or regional levels occurring. The carbon footprint of diets across the EU vary from country-to-country, and estimates vary depending on how much land use change is factored into these figures. Why? What are the major impacts of mass deforestation and forest loss? Increasing human dominance of tropical forests. Many consumers are concerned that their food choices are linked to deforestation in some of these hotspots. Each year, an estimated 15 billion trees are cut down around the world. Healthy communities: Tree-filled neighborhoods lower levels of domestic violence and are safer and more sociable. How many trees does IKEA cut down a Why should we care most about tropical deforestation? WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. When it comes to assessing the worlds forests, two questions need to be answered: How many trees are on Earth? and. People cut down 15 billion trees each year and the global tree count has fallen by 46% since the beginning of human civilization. The rate of deforestation is declining, but we still lost forests at a whopping 10 million hectares per year between 2015-2020. Not only would this be bad for people, it might also be bad for forests. Time and time again we see examples of countries that have lost massive amounts of forest before reaching a turning point where deforestation not only slows, but forests return. 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. Across Africa, fuelwood and charcoal played a much larger role it accounted for more than half (52%). To quote them, they wanted to prevent a common misperception that any tree cover loss shown on the map represents deforestation. For this reason, data sources including the UN Food and Agriculture Organization tend to aggregate annual losses as the average over five-year or decadal periods. 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. Africa is also an outlier as a result of how many people still rely on wood as their primary energy source. Some interesting facts state that every second, 1.5 acres of wood are cut down, Stage 2 The Early Transition phase is when countries start to lose forests very rapidly. The default is shown for Brazil, but you can explore the data for a range of countries using the Change country button. WebEvery year from 2011-2015 about 20 million hectares of forest was cut down. And its not just in forests eitherits also happening on farms, in cities, and on private property. Forests: this data is primarily sourced from the UN Food and Agriculture Organization (FAO). Web3.5 billion to 7 billion trees are cut down per year. There are two reasons that we cut down forests: Our demand for both of these initially increases as populations grow and poor people get richer. International trade is important for socioeconomic development. Data on the annual change in domestic forests is sourced from the UN FAOs Forest Resources Assessment. In Latin America and Southeast Asia in particular, commodity-driven deforestation mainly the clearance of forests to grow crops such as palm oil and soy, and pasture for beef production accounts for almost two-thirds of forest loss. Journal of Rural Studies, 15(1), 65-90.Mather, A. S., & Needle, C. L. (2000). 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. 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. 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. Notarnicola et al. Imagine over 100 large harvesters working non-stop. Forests still cover about 30 percent of the worlds land area, but they are disappearing at an alarming rate. But when forests are cut, burned or otherwise removed they emit carbon instead of absorb carbon. Global Forest Resources Assessment 2020: Main report. 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 researchers found that 36 million trees are cut down in urban areas each year, and 167,000 acres of impervious areas (concrete, asphalt, etc.) The biodiversity of managed tree plantations which are periodically cut, regrown, cut again, then regrown is not the same. On the x-axis we have imported deforestation. At their Global Forest Watch platform they were already presenting maps of forest loss across the world. Forest cover falls quickly, and the annual loss of forest is high. Data on net forest change, afforestation and deforestation is sourced from the UN Food and Agriculture Organizations Forest Resources Assessment. Lets take a look at which countries are causing deforestation overseas and the size of this impact. [2] Only 36% of the world's rainforests remain intact. Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. 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. The data produced by third parties and made available by Our World in Data is subject to the license terms from the original third-party authors. They first lose lots of forest, but reach a turning point and begin to regain it again. This is because the latter only captures deforestation the replacement of forest with another land use (such as cropland). We see massive differences in how important each driver is across the world. Stage 4 The Post-Transition phase is when countries have passed the transition point and are now gaining forest again. Cuaresma, J. C., Danylo, O., Fritz, S., McCallum, I., Obersteiner, M., See, L., & Walsh, B. What activities are driving this? Thats both an economic and environmental win. Because people are starting to see how climate change affects trees. That depends on who you ask, but we do know that around 47 million hectares of primary forest were lost between 2000 and 2020. Deforesting the earth: from prehistory to global crisis. The trees are not expected to regrow. Journal of Cleaner Production, 140, 753-765. England is similar: in the late 11th century, 15% of the country was forested, and over the following centuries two-thirds were cut down. Nature Sustainability, 1-9. (2020).References:FAO and UNEP. Explore palm oil production across the world, and its impacts on the environment. The State of the Worlds Forests 2020. 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%. But distilling changes to this single metric tree or forest loss comes with its own issues. A study published on September 2, 2015 in the journal Nature suggests these answers: 3 trillion and 15.3 billion. In the chart here we see the breakdown of deforestation emissions by product for each consumer country. Since 1961, the amount of land we use for agriculture increased by only 7%. In the chart we see how emissions from tropical deforestation are distributed through international supply chains. Firstly, international trade does play a role in deforestation its responsible for almost one-third of emissions. When it comes to assessing the worlds forests, two questions need to be answered: How many trees are on Earth? and. 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. See the distribution of global forests and which countries have the most forest cover. Since agriculture is responsible for 60 to 80% of it, what we eat, where its sourced from, and how it is produced is our strongest lever to bring deforestation to an end. How many trees are cut down each year?. Since 2016, an average of 28 million hectares have been cut down every year. Historical data pre-1990 is sourced from Michael Williams book, Deforesting the Earth: from prehistory to global crisis. Its domestic demand, not international trade, that is the main driver of deforestation. The researchs results are Imagine over 100 large harvesters working non-stop. 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. In a related article we look in much more detail at what agricultural products, and which countries are driving this. 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.) Our World in Data is free and accessible for everyone. From the chart we see that this was driven by the continued expansion of land for agriculture. and an argument for why deforestation is worse than degradation. It was a net importer. Biodiversity: The ravages of guns, nets and bulldozers. 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. The total cut down so far is over 470 million trees since January 1st. Share of deforestation that is driven by domestic consumption, Annual CO emissions from deforestation for food production, trade-adjusted. Even with the most basic of lifestyles compared to todays standards, the per capita footprint of our ancestors would have been large. But it was then that England reached its transition point and since then, forests have doubled in size. 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. Environmental Research Letters, 7(4), 044009. In a study published in Global Environmental Change, Florence Pendrill and colleagues investigated where tropical deforestation was occurring; what products were driving this; and, using global trade models, they traced where these products were going in international supply chains.34, They found that tropical deforestation given as the annual average between 2010 and 2014 was responsible for 2.6 billion tonnes of CO2 per year. If we fast-forward to 1700 when the global population had increased more than ten-fold, to 603 million. 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.) We lost 150 million hectares an area half the size of India during that decade. 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. (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. Maxwell, S. L., Fuller, R. A., Brooks, T. M., & Watson, J. E. (2016). You see that of the 14.9 billion hectares of land on the planet, only 71% of it is habitable the other 29% is either covered by ice and glaciers, or is barren land such as deserts, salt flats, or dunes. 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. In a previous post we looked at this change in global forests over the long-run. Nicolas-Jacques Cont, an officer in Napoleon's army, invented the modern pencil by combining graphite and clay for lead durability. How many trees are cut down each year in the Amazon rainforest? 79% of exported deforestation ended up in those countries that had stopped losing domestic forests. All of our charts can be embedded in any site. Net forest loss is not the same as deforestation it measures deforestation plus any gains in forest over a given period. There is little forest left. Why? According to the Environmental Paper Network, an estimated 30% of felled trees are used for paper products. Thats more than the countrys CO2 emissions from fossil fuels, which are around 2.2 tonnes per person. They should keep their domestic reforestation targets in perspective with their net impact on global forests. The change is permanent. Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. Nicolas-Jacques Cont, an officer in Napoleon's army, invented the modern pencil by combining graphite and clay for lead durability. How Many Trees are Cut down for Paper Each Year . Deforestation displaced: trade in forest-risk commodities and the prospects for a global forest transition. 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 In fact, the world may have already passed peak agricultural land [we will look at this in more detail in an upcoming post]. The problem is that it treats all forest loss as equal. 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. We need to pass the transition point as soon as possible, while minimising the amount of forest we lose along the way. Ellis, E. C., Beusen, A. H., & Goldewijk, K. K. (2020). Rather than looking at total figures by country [if youre interested, we have mapped them here] we have calculated the per capita footprint. This was first coined by Alexander Mather in the 1990s.Mather, A. S. (1990). Tropical forests and the changing earth system. Global deforestation peaked in the 1980s. Thats a lot of trees! Thats a lot of trees! After seeing this data, people might argue that we should cut back on trade. 40% of traded deforestation ends up in high-income countries, meaning they are responsible for 12% of deforestation.29. Since three-quarters of tropical deforestation is driven by agriculture, thats a valid concern. Data from 1990 onwards is sourced from the UNs 2020 Global Forest Resources Assessment 2020.References:Williams, M. (2003). With increasing development, urbanization and access to other energy resources, Africa will shift from local, subsistence activities into commercial commodity production both in agricultural products and timber extraction.
