Before we look at trends in deforestation across the world specifically, it's useful to understand the _net_ change in forest cover. The net change in forest cover measures any gains in forest cover – either through natural forest expansion or afforestation through tree-planting – minus deforestation. This map shows the net change in forest cover across the world. Countries with a positive change (shown in green) are regrowing forest faster than they're losing it. Countries with a negative change (shown in red) are losing more than they're able to restore. <Chart url="https://ourworldindata.org/grapher/annual-change-forest-area?stackMode=absolute®ion=World"/> <Callout title="A note on UN FAO forestry data"/> ## How much deforestation occurs each year? Net forest loss is not the same as deforestation – it measures deforestation plus any gains in forest over a given period. 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. The UN FAO estimate that 10 million hectares of forest were cut down each year. This interactive map shows deforestation rates across the world. <Chart url="https://ourworldindata.org/grapher/annual-deforestation?stackMode=absolute®ion=World"/> Many people think of environmental concerns as a modern issue: humanity’s destruction of nature and ecosystems as a result of very recent [population growth](http://ourworldindata.org/world-population-growth) and [increasing consumption](http://ourworldindata.org/economic-growth). This is true for some problems, such as climate change. But it’s not the case for deforestation. Humans have been cutting down trees for millennia. How much forest has the world lost? When in history did we lose it? In the chart we see how the cover of the earth’s surface has changed over the past 10,000 years. This is shortly after the end of the last great ice age, through to the present day.2 <Image filename="Global-forest-loss-since-ice-age.png"/> Let’s start at the top. 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. I have therefore excluded these categories so we can focus on how habitable land is used. The bar chart just below shows the earth’s surface cover just after the end of the last ice age.3 10,000 years ago 57% of the world’s habitable land was covered by forest. That’s [6 billion hectares](https://www.un.org/development/desa/en/news/forest/international-day-forests-2018.html). Today, only 4 billion hectares are left. The world has lost one-third of its forest – an area twice the size of the United States. Only 10% of this was lost in the first half of this period, until 5,000 years ago. The global population at this time was small and growing very slowly – there were [fewer than 50 million people](https://ourworldindata.org/grapher/world-population-1750-2015-and-un-projection-until-2100) in the world. The amount of [land per person](https://ourworldindata.org/grapher/total-agricultural-land-use-per-person?time=earliest..2016) that was needed to produce enough food was not small – in fact, it was much larger than today. 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. If we fast-forward to 1700 when the global population [had increased](https://ourworldindata.org/grapher/world-population-1750-2015-and-un-projection-until-2100) more than ten-fold, to 603 million. The amount of land used for agriculture – land to grow crops as well as grazing land for livestock – was expanding. You will notice in the chart that this was not only expanding into previously forested land, but also other land uses such as wild grasslands and shrubbery. Still, more than half of the world’s habitable land was forested. The turn of the 20th century is when global forest loss reached the halfway point: half of total forest loss occurred from 8,000 BC to 1900; the other half occurred in the last century alone. This emphasises two important points. 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. 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. Even with the most basic of lifestyles compared to today’s standards, the per capita footprint of our ancestors would have been large. Low agricultural productivity and a reliance on wood for fuel meant that large amounts of land had to be cleared for basic provisions. Second, it makes clear how much deforestation accelerated over the last century. In just over 100 years the world lost as much forest as it had in the previous 9,000 years. An area the size of the United States. From the chart we see that this was driven by the continued expansion of land for agriculture. When we think of the growing pressures on land from modern populations we often picture sprawling megacities. But urban land accounts for just 1% of global habitable land. Humanity’s biggest footprint is due to what we eat, not where we live. ### How can we put an end to our long history of deforestation? This might paint a bleak picture for the future of the world’s forests: the United Nations projects that the [global population will continue to grow](https://ourworldindata.org/world-population-growth#two-centuries-of-rapid-global-population-growth-will-come-to-an-end), reaching 10.8 billion by 2100. But there are real reasons to believe that this century doesn’t have to replicate the destruction of the last one. 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. Improvements in [crop yields](http://ourworldindata.org/crop-yields) mean the per capita demand for agricultural land continues to fall. We see this in the chart. Since 1961, the amount of land we use for agriculture [increased by only 7%](https://ourworldindata.org/grapher/agricultural-land?tab=chart&stackMode=relative&region=World). Meanwhile, the global [population increased](https://ourworldindata.org/grapher/population?time=1961..2018&country=~OWID_WRL) by 147% – from 3.1 to 7.6 billion.4 This means that agricultural land _per person_ more than halved, from 1.45 to 0.63 hectares. In fact, the world [may have already passed](https://ourworldindata.org/grapher/agricultural-land?tab=chart&stackMode=absolute&region=World) ‘peak agricultural land’ _[we will look at this in more detail in an upcoming post]_. 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. If we can take advantage of these innovations, we can bring deforestation to an end. A future with more people _and_ more forest is possible. <Chart url="https://ourworldindata.org/grapher/agricultural-area-per-capita?tab=chart®ion=World"/> ## Global deforestation peaked in the 1980s. Can we bring it to an end? Since the end of the last great ice age – 10,000 years ago – the world has lost one-third of its forests.5 Two billion hectares of forest – an area twice the size of the United States – has been cleared to grow crops, raise livestock, and use for fuelwood. In a [previous post](https://ourworldindata.org/deforestation#the-world-has-lost-one-third-of-its-forests-but-an-end-of-deforestation-is-possible) we looked at this change in global forests over the long-run. What this showed was that although humans have been deforesting the planet for millennia, the rate of forest loss accelerated rapidly in the last few centuries. Half of global forest loss occurred between 8,000BC and 1900; the other half was lost in the last century alone. To understand this more recent loss of forest, let’s zoom in on the last 300 years. The world lost 1.5 billion hectares of forest over that period. That’s an area 1.5-times the size of the United States. In the chart we see the decadal losses and gains in global forest cover. On the horizontal axis we have time, spanning from 1700 to 2020; on the vertical axis we have the decadal change in forest cover. The taller the bar, the larger the change in forest area. This is measured in hectares, which is equivalent to 10,000 m². Forest loss measures the net change in forest cover: the loss in forests due to deforestation plus any expansion of forest through afforestation.6 Unfortunately there is no single source that provides consistent and transparent data on deforestation rates over this period of time. Methodologies change over time, and estimates – especially in earlier periods – are highly uncertain. This means I’ve had to use two separate datasets to show this change over time. As we’ll see, they produce different estimates of deforestation for an overlapping decade – the 1980s – which suggests that these are not directly comparable. I do not recommend combining them into a single series, but the overall trends are still applicable and tell us an important story about deforestation over the last three centuries. The first series of data comes from Williams (2006), who estimates deforestation rates from 1700 to 1995.7 Due to poor data resolution, these are often given as average rates over longer periods – for example, annual average rates are given over the period from 1700 to 1849, and 1920 to 1949. That’s why these rates look strangely consistent over long period of time. The second series comes from the UN Food and Agriculture Organization (FAO). It produces a new assessment of global forests every 5 years.8 <Image filename="global-deforestation-1700s.png"/> The rate and location of forest loss changed a lot. From 1700 to 1850, 19 million hectares were being cleared every decade. That’s around half the size of Germany. It was most temperate forests across Europe and North America that were being lost at this time. Population growth meant that today’s rich countries needed more and more resources such as land for agriculture, wood for energy, and for construction.9 Moving into the 20th century there was a stepwise change in demand for agricultural land and energy from wood. Deforestation rates accelerated. And the hotspot of deforestation changed from the equivalent to the area of South Africa. This increase was mostly driven by tropical deforestation as countries across Asia and Latin America. Global forest loss appears to have reached its peak in the 1980s. The two sources do not agree on the magnitude of this loss: Williams (2006) estimates a loss of 150 million hectares – an area half the size of India – during that decade. Interestingly, the UN FAO 1990 report also estimated that _deforestation_ in tropical ‘developing’ countries was 154 million hectares. But, it estimated that regrowth of old forests offset some of these losses, leading to a net loss of 102 million hectares.10 The latest UN Forest Resources Assessment estimates that the net loss in forests has declined in the last three decades, from 78 million hectares in the 1990s to 47 million hectares in the 2010s. This data maps an expected pathway based on what we know from how human-forest interactions evolve. As we explore in more detail in our [related article](https://ourworldindata.org/deforestation#forest-transitions-why-do-we-lose-then-regain-forests), countries tend to follow a predictable development in forest cover, a U-shaped curve.11 They lose forests as populations grow and demand for agricultural land and fuel increases, but eventually they reach the so-called ‘forest transition point’ where they begin to regrow more forests than they lose. That is what has happened in temperate regions: they have gone through a period of high deforestation rates, before a slowing and reversal of this trend. However, many countries – particularly in the tropics and sub-tropics – are still moving through this transition. Deforestation rates are still very high. --- ### Deforestation rates are still high across the tropics Large areas of forest are still being lost in the tropics today. This is particularly tragic because these are regions with very high concentrations of biodiversity. Let’s look at estimates of deforestation from the latest UN Forest report. This shows us raw deforestation rates, without any adjustment for the regrowth or plantation of forests, which is arguably not as good for ecosystems or carbon storage. This is shown in the chart below. We can see that the UN does estimate that deforestation rates have fallen since the 1990s. However, there was very little progress from the 1990s to 2000s, and an estimated 26% drop in rates in the 2010s. In 2022, the FAO published [a separate assessment](https://www.fao.org/forest-resources-assessment/remote-sensing/fra-2020-remote-sensing-survey/en/) based on Remote Sensing methods; it did not report data for the 1990s, but also estimated a 29% reduction in deforestation rates from early 2000s to the 2010s. <Image filename="global-deforestation-1990s-onwards.png"/> This is progress, but it needs to happen much faster. The world is still losing large amounts of primary forests every year. To put these numbers in context: during the 1990s and first decade of the 2000s, an area almost the size of India was deforested.12 Even with the ‘improved’ rates in the 2010s, this still amounted to an area around twice the size of Spain.13 The regrowth of forests is a positive development. In the chart below, we see how this affects the _net change_ in global forests. Forest recovery and plantation ‘offsets’ a lot of deforestation such that the net losses are around half the rates of deforestation alone. <Image filename="global-deforestation-net-loss.png"/> But we should be cautious here: it’s often not the case that the ‘positives’ of regrowing one hectare of forest offset the ‘losses’ of one hectare of deforestation. Cutting down one hectare of rich, tropical rainforest cannot be completely offset by the plantation of forest in a temperate country. Forest expansion is positive, but does not negate the need to finally end deforestation. 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. But, the fact that forest transitions are possible should give us confidence that a positive future is possible. Many countries have not only ended deforestation, but actually achieved substantial reforestation. It will be possible for our generation to achieve the same on the global scale and bring the 10,000 year history of forest loss to an end. If we want to end deforestation we need to understand where and why it’s happening; where countries are within their transition; and what can be done to accelerate their progress through it. We need to pass the transition point as soon as possible, while minimising the amount of forest we lose along the way. In [this article](https://ourworldindata.org/what-are-drivers-deforestation) I look at what’s driving deforestation: that helps us understand what we need to do to solve it. --- ### Forest definitions and comparisons to other datasets There is no universal definition of what a ‘forest’ is. That means there are a range of estimates of forest area, and how this has changed over time. In this article, in the recent period I have used data from the UN’s Global Forest Resources Assessment (2020). The UN carries out these global forest stocktakes every five years. These forest figures are widely-used in research, policy, and international targets, such as in the [Sustainable Development Goals](https://unstats.un.org/sdgs/metadata/files/Metadata-15-01-01.pdf). The UN FAO has a very specific definition of a forest. It’s “land spanning more than 0.5 hectares with trees higher than 0.5 meters and a canopy cover of more than 10%, or trees able to reach these thresholds in situ.” In other words, it has criteria for the area that must be covered (0.5 hectares), the minimum height of trees (0.5 meters) and a density of at least 10%. Compare this to the UN Framework on Climate Change (UNFCCC), which uses forest estimates to calculate land use carbon emissions, and for its REDD+ programme, where low-to-middle income countries can receive finance for verified projects that prevent or reduce deforestation. It [defines a forest](https://www.un-redd.org/glossary/forest) as having a density of 10-30%, a minimum tree height of 2-5 meters, and a smaller area of 0.1 hectares. It’s not just forest definitions that vary between sources. What is measured (and not measured) differs too. [Global Forest Watch](https://www.globalforestwatch.org/) is an interactive online dashboard that tracks ‘tree loss’ and ‘forest loss’ across the world. It measures this in real-time, and can provide better estimates of year-to-year variations in rates of tree loss. However, the UN FAO and Global Forest Watch do not measure the same thing. The UN FAO measures _deforestation_ based on how land is used. It measures the permanent conversion of forested land to another use, such as pasture, croplands, or urbanization. Temporary changes in forest cover, such as losses through wildfire, or small-scale shifting agriculture are not included in deforestation figures, because it is assumed that they will regrow. If the use of land has not changed, it is not considered deforestation. Global Forest Watch (GFW) measures temporary changes in forests. It can detect changes in land _cover_, but does not differentiate the underlying land use. All deforestation would be considered tree loss, but a lot of tree loss would not be considered as deforestation. As GFW describes in its definition of ‘forest loss’: “Loss” indicates the removal or mortality of tree cover and can be due to a variety of factors, including mechanical harvesting, fire, disease, or storm damage. As such, “loss” does not equate to deforestation.” We therefore cannot directly compare these sources. This [article](https://www.globalforestwatch.org/blog/data-and-research/global-forest-watch-and-the-forest-resources-assessment-explained-in-5-graphics-2/) from Global Forest Watch gives a good overview of the differences between the UN FAO and GFW methods. Since GFW uses satellite imagery, its methods continually improve. This makes its ability to detect changes in forest cover even stronger. But it also means that comparisons over time are more difficult. It currently warns against comparing pre-2015 and post-2015 data since there was a significant methodological change at that time. Note that this is also a problem in UN FAO reports, as I’ll soon explain. What data from GFW makes clear is that forest loss across the tropics is still very high, and in the last few years, little progress has been made. Since UN FAO reports are only published in 5-year intervals, they miss these shorter-term fluctuations in forest loss. The GFW’s shorter-interval stocktakes of how countries are doing will become increasingly valuable. --- One final point to note is that UN FAO estimates have also changed over time, with improved methods and better access to data. I looked at how net forest loss rates in the 1990s were reported across five UN reports: 2000, 2005, 2010, 2015 and 2020. Estimated rates changed in each successive report: * [2000 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2000/en/): Net losses of 92 million hectares * [2005 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2005/en/): 89 million hectares * [2010 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2010/en/): 83 million hectares * [2015 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2015/en/): 72 million hectares * [2020 report](https://www.fao.org/documents/card/en/c/ca9825en): 78 million hectares This should not affect the overall trends reported in the latest report: the UN FAO should – as far as is possible – apply the same methodology to its 1990s, 2000s, and 2010s estimates. However, it does mean we should be cautious about comparing absolute magnitudes across different reports. This is one challenge in presenting 1980 figures in the main visualization in this article. Later reports have not updated 1980 figures, so we have to rely on estimates from earlier reports. We don’t know whether 1980s rates would also be lower with the UN FAO’s most recent adjustments. If so, this would mean the reductions in net forest loss from the 1980s to 1990s were lower than is shown from available data. ## Forest Transitions: why do we lose then regain forests? Globally we deforest around ten million hectares of forest every year.14 That’s an area the size of Portugal every year. Around half of this deforestation is offset by regrowing forests, so overall we lose around five million hectares each year. Nearly all – 95% – of this deforestation [occurs in the tropics](https://ourworldindata.org/deforestation#not-all-forest-loss-is-equal-what-is-the-difference-between-deforestation-and-forest-degradation). But not all of it is to produce products for local markets. 14% of deforestation is driven by consumers in the world’s richest countries – we import beef, vegetable oils, cocoa, coffee and paper that has been produced on deforested land.15 The scale of deforestation today might give us little hope for protecting our diverse forests. But by studying how forests have changed over time, there’s good reason to think that a way forward is possible. ### Many countries have lost then regained forest over millennia 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. 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). I have reconstructed long-term data using various studies which I’ve [documented here](https://docs.google.com/spreadsheets/d/1nYpao4e8Ai-P86jIUZ3r7X6-5MjZ7ZbG7TJQSO729Bg/edit?usp=sharing). Many countries have much less forest today than they did in the past. Nearly half (47%) of France was forested 1000 years ago; today that’s just under one-third (31.4%). The same is true of the United States; back in 1630 46% of the area of today’s USA was covered by forest. Today that’s just 34%. 1000 years ago, 20% of Scotland’s land was covered by forest. By the mid-18th century, only 4% of the country was forested. But then the trend turned, and it moved from deforestation to reforestation. For the last two centuries forests have been growing and are almost back to where they were 1000 years ago.16 <Chart url="https://ourworldindata.org/grapher/forest-area-as-share-of-land-area?tab=chart&time=earliest..latest&country=England~Scotland~FRA~USA®ion=World"/> ### Forest Transitions: the U-shaped curve of forest change What’s surprising is how consistent the pattern of change is across so many countries; as we’ve seen they all seem to follow a ‘U-shaped curve’. They first lose lots of forest, but reach a turning point and begin to regain it again. We can illustrate this through the so-called ‘Forest Transition Model’.17 This is shown in the chart. It breaks the change in forests into four stages, explained by two variables: the amount of forest cover a region has, and the annual _change_ in cover (how quickly it is losing or gaining forest).18 Stage 1 – The Pre-Transition phase is defined by having high levels of forest cover _and_ no or only very slow losses over time. Countries may lose some forest each year, but this is at a very slow rate. Mather refers to an annual loss of less than 0.25% as a small loss. Stage 2 – The Early Transition phase is when countries start to lose forests very rapidly. Forest cover falls quickly, and the annual loss of forest is high. Stage 3 – The Late Transition phase is when deforestation rates start to slow down again. At this stage, countries are still losing forest each year but at a lower rate than before. At the end of this stage, countries are approaching the ‘transition point’. Stage 4 – The Post-Transition phase is when countries have passed the ‘transition point’ and are now gaining forest again. At the beginning of this phase, the forest area is at its lowest point. But forest cover increases through reforestation. The annual change is now positive. <Image filename="Forest-Transition-Model-01.png"/> ### Why do countries lose then regain forest? Many countries have followed this classic U-shaped pattern. What explains this? There are two reasons that we cut down forests: * Forest resources: we want the resources that they provide – the wood for fuel, building materials, or paper; * Land: – we want to use the land they occupy for something else – farmland to grow crops; pasture to raise livestock; or land to build roads and cities. Our demand for both of these initially increases as [populations grow](http://ourworldindata.org/world-population-growth) and poor [people get richer](http://ourworldindata.org/economic-growth). We need more fuelwood to cook, more houses to live in, and importantly, more food to eat. But, as countries continue to get richer this demand slows. The rate of population growth tends to slow down. Instead of using wood for fuel we switch to [fossil fuels](http://ourworldindata.org/fossil-fuels), or hopefully, more [renewables](http://ourworldindata.org/renewable-energy) and [nuclear energy](http://ourworldindata.org/nuclear-energy). Our [crop yields](http://ourworldindata.org/crop-yields) improve and so we need less land for agriculture. This demand for resources and land is not always driven by domestic markets. As I mentioned earlier, 14% of deforestation today is driven by consumers in rich countries. The Forest Transition therefore tends to follow a ‘development’ pathway.19 As a country achieves economic growth it moves through each of the four stages. This explains historical trends we see for countries across the world today. Rich countries – such as the USA, France and the United Kingdom – have had a long history of deforestation but are now passed the transition point. Most deforestation today occurs in low-to-middle income countries. ### Where are countries in the transition today? 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. Most of our future deforestation is going to come from countries in the pre- or early-transition phase. Several studies have assessed the stage of countries across the world.20 The most recent analysis to date was published by Florence Pendrill and colleagues (2019) which looked at each country’s stage in the transition, the drivers of deforestation but also the role of international trade.21 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. In the map we see their assessment of each country’s stage in the transition. Most of today’s richest countries – all of Europe, North America, Japan, South Korea – have passed the turning point and are now regaining forest. This is also true for major economies such as China and India. That these countries have recently regained forests is also visible in the long-term forest trends above. Across sub-tropical countries we have a mix: many upper-middle income countries are now in the late transition phase. 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. Countries such as Indonesia, Myanmar, and the Democratic Republic of Congo are in the early transition phase and are losing forests quickly. Some of the world’s poorest countries are still in the pre-transition phase. 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. <Chart url="https://ourworldindata.org/grapher/forest-transition-phase?stackMode=absolute®ion=World"/> ## Not all forest loss is equal: what is the difference between deforestation and forest degradation? 15 billion trees are cut down every year.22 The [Global Forest Watch](https://www.globalforestwatch.org/dashboards/global/) project – using satellite imagery – estimates that global tree loss in 2019 was 24 million hectares. That’s an area the size of the United Kingdom. These are big numbers, and important ones to track: forest loss creates a number of negative impacts, ranging from carbon emissions to species extinctions and biodiversity loss. But distilling changes to this single metric – tree or forest loss – comes with its own issues. The problem is that it treats all forest loss as equal. It assumes the impact of clearing primary rainforest in the Amazon to produce soybeans is the same as logging planted forests in the UK. The latter will experience short-term environmental impacts, but will ultimately regrow. When we cut down primary rainforest we are transforming this ecosystem forever. When we treat these impacts equally we make it difficult to prioritize our efforts in the fight against deforestation. Decisionmakers could give as much of our attention to European logging as to destruction of the Amazon. As we will see later, this would be a distraction from our primary concern: ending tropical deforestation. The other issue that arises is that ‘tree loss’ or ‘forest loss’ data collected by satellite imagery often doesn’t match the official statistics reported by governments in their land use inventories. This is because the latter only captures _deforestation_ – the replacement of forest with another land use (such as cropland). It doesn’t capture trees that are cut down in planted forests; the land is still forested, it’s now just regrowing forest. 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. ### Understanding and seeing the drivers of forest loss ‘Forest loss’ or ‘tree loss’ captures two fundamental impacts on forest cover: _deforestation_ and _forest degradation_. _Deforestation_ is the complete removal of trees for the conversion of forest to another land use such as agriculture, mining, or towns and cities. It results in a permanent conversion of forest into an alternative land use. The trees are _not expected to regrow_. _Forest degradation_ measures a thinning of the canopy – a reduction in the density of trees in the area – but without a change in land use. The changes to the forest are often temporary and it’s expected that they will regrow. From this understanding we can define five reasons why we lose forests: * Commodity-driven deforestation is the long-term, permanent conversion of forests to other land uses such as agriculture (including oil palm and cattle ranching), mining, or energy infrastructure. * Urbanization is the long-term, permanent conversion of forests to towns, cities and urban infrastructure such as roads. * Shifting agriculture is the small to medium-scale conversion of forest for farming, that is later abandoned so that forests regrow. This is common of local, subsistence farming systems where populations will clear forest, use it to grow crops, then move on to another plot of land. * Forestry production is the logging of managed, planted forests for products such as timber, paper and pulp. These forests are logged periodically and allowed to regrow. * Wildfires destroy forests temporarily. When the land is not converted to a new use afterwards forests can regrow in the following years. Thanks to satellite imagery, we can get a birds-eye view of what these drivers look like from above. In the figure we see visual examples from the study of forest loss classification by Philip Curtis et al. (2018), published in _Science_.23 <Image filename="Identifying-drivers-of-forest-loss.png"/> 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. The change is permanent. There is little forest left. Forestry production and wildfires usually result in _forest degradation_ – the forest experiences short-term disturbance but if left alone is likely to regrow. The change is temporary. This is nearly always true of planted forests in temperate regions – there, planted forests are long-established and do not replace primary existing forests. 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 'Shifting agriculture’ is usually classified as degradation because the land is often abandoned and the forests regrow naturally. But it can bridge between deforestation and degradation depending on the timeframe and permanence of these agricultural practices. ### One-quarter of forest loss comes from tropical deforestation We’ve seen the five key drivers of forest loss. Let’s put some numbers to them. In their analysis of global forest loss, Philip Curtis and colleagues used satellite images to assess where and why the world lost forests between 2001 and 2015. The breakdown of forest loss globally, and by region, is shown in the chart.23 Just over one-quarter of global forest loss is driven by deforestation. 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%). We see massive differences in how important each driver is across the world. 95% of the world’s deforestation occurs in the tropics [we look at this breakdown again later]. 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. In contrast, most forest degradation – two-thirds of it – occurs in temperate countries. 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](https://ourworldindata.org/deforestation#global-deforestation-peaked-in-the-1980s-can-we-bring-it-to-an-end)__]_. They cut down their forests and replaced it with agricultural land long ago. 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. Africa is also different here. Forests are mainly cut and burned to make space for local, subsistence agriculture or for fuelwood for energy. 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. <Image filename="Forest-loss-by-driver-and-region.png"/> Africa is also an outlier as a result of how many people still rely on wood as their primary energy source. Noriko Hosonuma et al. (2010) looked at the primary drivers of deforestation and degradation across tropical and subtropical countries specifically.24 The breakdown of forest degradation drivers is shown in the following chart. Note that in this study, the category of subsistence agriculture was classified as a _deforestation_ driver, and so is not included. In Latin America and Asia the dominant driver of _degradation_ was logging for products such as timber, paper and pulp – this accounted for more than 70%. Across Africa, fuelwood and charcoal played a much larger role – it accounted for more than half (52%). This highlights an important point: [less than 20%](https://ourworldindata.org/grapher/access-to-clean-fuels-and-technologies-for-cooking?tab=chart&time=earliest..latest&country=~Sub-Saharan%20Africa) of people in Sub-Saharan Africa have access to clean fuels for cooking, meaning they still rely on wood and charcoal. 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. This follows the classic ‘forest transition’ model with development, which we look at in more detail in a [related article](https://ourworldindata.org/deforestation#forest-transitions-why-do-we-lose-then-regain-forests). <Image filename="Drivers-of-forest-degradation.png"/> ### Tropical deforestation should be our primary concern The world loses almost six million hectares of forest each year to deforestation. That’s like losing an area the size of Portugal every two years. 95% of this occurs in the tropics. The breakdown of deforestation by region is shown in the chart. 59% occurs in Latin America, with a further 28% from Southeast Asia. In a [related article](https://ourworldindata.org/drivers-of-deforestation) we look in much more detail at what agricultural products, and which countries are driving this. As we saw previously, this deforestation accounts for around one-quarter of global forest loss. 27% of forest loss results from ‘commodity-driven deforestation’ – cutting down forests to grow crops such as soy, palm oil, cocoa, to raise livestock on pasture, and mining operations. Urbanization, the other driver of deforestation accounts for just 0.6%. It’s the foods and products we buy, not where we live, that has the biggest impact on global land use. It might seem odd to argue that we should focus our efforts on tackling this quarter of forest loss (rather than the other 73%). But there is good reason to make this our primary concern. Philipp Curtis and colleagues make this point clear. At their [Global Forest Watch](https://www.globalforestwatch.org/) platform they were already presenting maps of forest loss across the world. But they wanted to contribute to a more informed discussion about where to focus forest conservation efforts by understanding _why_ forests were being lost. To quote them, they wanted to prevent “a common misperception that any tree cover loss shown on the map represents deforestation”. And to “identify where deforestation is occurring; perhaps as important, show where forest loss is not deforestation”. Why should we care most about tropical deforestation? There is a geographical argument (why the tropics?) and an argument for why deforestation is worse than degradation. Tropical forests are home to some of the richest and most diverse ecosystems on the planet. Over half of the world’s species reside in tropical forests.25 Endemic species are those which only naturally occur in a single country. Whether we look at the distribution of endemic [mammal species](https://ourworldindata.org/grapher/endemic-mammal-species-by-country), [bird species](https://ourworldindata.org/grapher/endemic-bird-species-by-country), or [amphibian species](https://ourworldindata.org/grapher/endemic-amphibian-species-by-country), the map is the same: subtropical countries are packed with unique wildlife. Habitat loss is the leading driver of global biodiversity loss.26 When we cut down rainforests we are destroying the habitats of many unique species, and reshaping these ecosystems permanently. Tropical forests are also large carbon sinks, and can store a lot of carbon per unit area.27 Deforestation also results in larger losses of biodiversity and carbon relative to degradation. 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. But the magnitude of these impacts are often less than the complete conversion of forest. They are smaller, and more temporary. When deforestation happens, almost all of the carbon stored in the trees and vegetation – called the ‘aboveground carbon loss’ – is lost. Estimates vary, but on average only 10-20% of carbon is lost during logging, and 10-30% from fires.28 In a study of logging practices in the Amazon and Congo, forests retained 76% of their carbon stocks shortly after logging.29 Logged forests recover their carbon over time, as long as the land is not converted to other uses (which is what happens in the case of deforestation). Deforestation tends to occur on forests that have been around for centuries, if not millennia. Cutting them down disrupts or destroys established, species-rich ecosystems. The biodiversity of managed tree plantations which are periodically cut, regrown, cut again, then regrown is not the same. That is why we should be focusing on tropical deforestation. Since agriculture is responsible for 60 to 80% of it, what we eat, where it’s sourced from, and how it is produced is our strongest lever to bring deforestation to an end. <Image filename="Forest-loss-by-driver.png"/> ## Do rich countries import deforestation from overseas? There is a marked divide in the state of the world’s forests. In most rich countries, across Europe, North America and East Asia, [forest cover is increasing](https://ourworldindata.org/grapher/change-forest-vs-gdp?tab=chart&stackMode=absolute&country=&region=World), whilst in many low-to-middle income countries it’s decreasing. But, it would be wrong to think that the only impact rich countries have on global forests is through changes in their domestic forests. They also contribute to global deforestation through the foods they import from poorer countries. Today, most deforestation occurs in the tropics. 71% of this is driven by demand in domestic markets, and the remaining 29% for the production of products that are traded. 40% of traded deforestation ends up in high-income countries, meaning they are responsible for 12% of deforestation.30 Let’s take a look at which countries are causing deforestation overseas and the size of this impact. ### Which countries are causing deforestation overseas? How much do people in rich countries contribute to deforestation overseas? To investigate this question, researchers Florence Pendrill et al. (2019) quantified the deforestation embedded in traded goods between countries.21 They did this by calculating the amount of deforestation associated with specific food and forestry products, and combining it with a trade model. In the map we see the _net_ deforestation embedded in trade for each country. This is calculated by taking each country’s _imported_ deforestation and subtracting its _exported_ deforestation. Net importers of deforestation (shown in brown) are countries that contribute more to deforestation in other countries than they do in their home country. The consumption choices of people in these countries cause deforestation elsewhere in the world. <Chart url="https://ourworldindata.org/grapher/net-deforestation-in-trade?stackMode=absolute®ion=World"/> For example, after we adjust for all the goods that the UK imports and exports, it caused more deforestation elsewhere than it did domestically. It was a net importer. Brazil, in contrast, caused more deforestation domestically in the production of goods for other countries than it imported from elsewhere. It was a net exporter. 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. they’re driving deforestation elsewhere; whilst many subtropical countries are partly cutting down trees to meet this demand from rich countries. Most deforestation occurs for the production of goods that are consumed within domestic markets. 71% of deforestation is for domestic production. Less than one-third (29%) is for the production of goods that are traded. High-income countries were the largest 'importers' of deforestation, accounting for 40% of it. This means they were responsible for 12% of global deforestation.31 It is therefore true that rich countries are causing deforestation in poorer countries. ### Are countries importing more deforestation than they’re regrowing domestically? Many rich countries are driving deforestation in other parts of the world, but are regrowing forests domestically. 79% of exported deforestation ended up in those countries that had stopped losing domestic forests. How do these two measures compare? Are they causing more deforestation elsewhere than they are regenerating in forests at home? Let’s take an example. 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. 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. Not all forest is equal. Tropical forests are often more productive than temperate forests, meaning they store more carbon. They are also richer sites of biodiversity. And, we might place more value on preserving primary, native forests that haven’t yet been deforested over regrowing forests that have lost their previous ecosystems. Hence, we should keep in mind that forest area is not the only aspect that matters – where that forest is and how rich in life it is matters too. It would be good if there was data available that would capture these additional aspects. We manage to capture some of these differences in carbon in our related article on [deforestation ](https://ourworldindata.org/deforestation#carbon-emissions-from-deforestation-are-they-driven-by-domestic-demand-or-international-trade)_[emissions](https://ourworldindata.org/deforestation#carbon-emissions-from-deforestation-are-they-driven-by-domestic-demand-or-international-trade)_ [embedded in trade](https://ourworldindata.org/deforestation#carbon-emissions-from-deforestation-are-they-driven-by-domestic-demand-or-international-trade). Without reliable metrics that capture all of these differences, we will have to stick with total changes in forest area for now. But we should keep these important aspects in mind when comparing forest losses and gains. 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. Since there is often year-to-year variability in deforestation or reforestation rates, this is shown as the five-year average. On the x-axis we have imported deforestation. The grey line marks where the area of domestic regrowth of forests is exactly equal to imported deforestation. Countries that lie along this line would have a net-neutral impact on global forests: the area they are causing to deforestation overseas is exactly as large as the area they are regrowing at home. <Chart url="https://ourworldindata.org/grapher/domestic-forest-change-vs-imported-deforestation?tab=chart&stackMode=absolute&country=®ion=World"/> 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. For example, the US ‘imported’ 64,000 hectares of deforested land, but increased its domestic forest area by 275,000 hectares. More than four times as much. On balance, they add to the global forest stock. Countries below the line – such as the UK and Germany – are not growing forests fast enough to offset the deforestation they’re creating elsewhere. The UK ‘imported’ 34,000 hectares of deforestation but increased its domestic forests by only 19,000 hectares. These countries might have high levels of afforestation at home, but they’re still having a net negative impact on the size of the world’s forests. ### Rich countries need to be more conscious of how they’re contributing to global deforestation After seeing this data, people might argue that we should cut back on trade. If poorer countries are cutting down forests to make food for rich consumers, then we should just stop trading these goods. But the solution is not so simple. There are other aspects to consider. International trade is important for socioeconomic development. Many farmers rely on international buyers to earn a living and improve their livelihoods. Not only would this be bad for people, it might also be bad for forests. One of the reasons poorer countries clear forest to make room for farmland is that they achieve low [crop yields](http://ourworldindata.org/crop-yields). If you struggle to increase crop yields but want to produce more food, then expanding your agricultural land is the only option. This often comes at the cost of forests. Improvements in agricultural productivity tends to both drive and follow [economic growth](http://ourworldindata.org/economic-growth). 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. So, what can we do? 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. 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. That’s both an economic and environmental win. The first step in doing this is for rich countries to monitor their deforestation impacts overseas more closely. They should keep their domestic reforestation targets in perspective with their net impact on global forests. Sometimes these restoration programmes pale in comparison to the deforestation they’re driving elsewhere. ## Carbon emissions from deforestation: are they driven by domestic demand or international trade? 95% of global deforestation occurs in the tropics. Brazil and Indonesia alone account for almost half. After long periods of forest clearance in the past, most of today’s richest countries are increasing tree cover through afforestation. This might put the responsibility for ending deforestation solely on tropical countries. But, supply chains are international. What if this deforestation is being driven by consumers elsewhere? Many consumers are concerned that their food choices are linked to deforestation in some of these hotspots. Since three-quarters of tropical deforestation is driven by agriculture, that’s a valid concern. It feeds into the popular idea that ‘eating local’ is one of the best ways to reduce your carbon footprint. In a [previous article](https://ourworldindata.org/food-choice-vs-eating-local) I showed that the types of food you eat matter _much_ more for your carbon footprint than where it comes from – this is because transport usually makes up a small percentage of your food’s emissions, even if it comes from the other side of the world. If you want to reduce your carbon footprint, reducing meat and dairy intake – particularly beef and lamb – has the largest impact. But, understanding the role of deforestation in the products we buy is important. If we can identify the producer countries, importing countries, and specific products responsible, we can direct our efforts towards interventions that will really make a difference. ## One-third of CO2 emissions from deforestation are embedded in international trade 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. That was 6.5% of global CO2 emissions.35 International trade was responsible for around one-third (29%) of these emissions. This is probably less than many people would expect. Most emissions – 71% – came from foods consumed in the country that they were produced. It’s domestic demand, not international trade, that is the main driver of deforestation. In the chart we see how emissions from tropical deforestation are distributed through international supply chains. 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 paths between these end boxes indicate where emissions are being traded – the wider the bar, the more emissions are embedded in these products. Latin America exports around 23% of its emissions; that means more than three-quarters are generated for products that are consumed within domestic markets. The Asia-Pacific region – predominantly Indonesia and Malaysia – export a higher share: 44%. As we will see later, this is dominated by palm oil exports to Europe, China, India, North America and the Middle East. Deforestation in Africa is mainly driven by local populations and markets; only 9% of its emissions are exported. Since international demand is driving one-third of deforestation emissions, we have some opportunity to reduce emissions through global consumers and supply chains. But most emissions are driven by domestic markets – this means policies in the major producer countries will be key to tackling this problem. <Image filename="Deforestation-emissions-in-trade-–-Sankey-01.png"/> ## How much deforestation emissions is each country responsible for? Let’s now focus on the consumers of products driving deforestation. After we adjust for imports and exports, how much CO2 from deforestation is each country responsible for? Rather than looking at total figures by country [if you’re interested, we have mapped them [here](https://ourworldindata.org/grapher/co2-deforestation-for-food?stackMode=absolute&region=World)] we have calculated the per capita footprint. This gives us an indication of the impact of the average person’s diet. Note that this only measures the emissions from tropical deforestation – it doesn’t include any other emissions from agricultural production, such as methane from livestock, or rice, or the use of fertilizers. In the chart we see deforestation emissions per person, measured in tonnes of CO2 per year. For example, the average German generated half a tonne (510 kilograms) of CO2 per person from domestic and imported foods. At the top of the list we see some of the major _producer_ countries – Brazil and Indonesia. The fact that the per capita emissions _after_ trade are very high means that a lot of their food products are consumed by people in Brazil and Indonesia. The diet of the average Brazilian creates 2.7 tonnes of CO2 from deforestation alone. That’s more than the country’s CO2 [emissions from fossil fuels](https://ourworldindata.org/explorers/co2?tab=chart&xScale=linear&yScale=linear&stackMode=absolute&endpointsOnly=0&time=earliest..latest&country=China~United%20States~India~United%20Kingdom~World&region=World&Gas%20=CO%E2%82%82&Accounting%20=Production-based&Fuel%20=Total&Count%20=Per%20capita&Relative%20to%20world%20total%20=), which are around 2.2 tonnes per person. But we also see that some countries which import a lot of food have high emissions. Luxembourg has the largest footprint at nearly three tonnes per person. Imported emissions are also high for Taiwan, Belgium and the Netherlands at around one tonne. The average across the EU was 0.3 tonnes CO2 per person. To put this in perspective, that would be around one-sixth of the total carbon footprint of the average EU diet.36 <Chart url="https://ourworldindata.org/grapher/per-capita-co2-food-deforestation?tab=chart&stackMode=absolute&time=earliest..latest®ion=World"/> ## Beef, soybeans and palm oil are the key drivers of deforestation We know where deforestation emissions are occurring, and where this demand is coming from. But we also need to know what products are driving this. This helps consumers understand what products they should be concerned about, but also allows us to target specific supply chains. As we covered in a [previous article](https://ourworldindata.org/drivers-of-deforestation), 60% of tropical deforestation is driven by beef, soybean and palm oil production. We should not only look at where these foods are produced, but also where the consumer demand is coming from. In the chart here we see the breakdown of deforestation emissions by product for each consumer country. The default is shown for Brazil, but you can explore the data for a range of countries using the “Change country” button. We see very clearly that the large Brazilian footprint is driven by its domestic demand for beef. 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. Across the US and Europe the breakdown of products is more varied. But, overall, oilseeds and beef tend to top the list for most countries. Bringing all of these elements together, we can focus on a few points that should help us prioritise our efforts to end deforestation. Firstly, international trade does play a role in deforestation – it’s responsible for almost one-third of emissions. By combining our earlier Sankey diagram, and breakdown of emissions by product, we can see that we can tackle a large share of these emissions through only a few key trade flows. Most traded emissions are embedded in soy and palm oil exports to China and India; and beef, soy and palm oil exports to Europe. The story of both soy and palm oil are complex – and it’s not obvious that eliminating these products will fix the problem. We therefore look at them both individually in more detail, to better understand what we can do about it. But international markets alone cannot fix this problem. Most tropical deforestation is driven by demand for products in domestic markets. Brazil’s emissions are high because Brazilians eat a lot of beef. Africa’s emissions are high because people are clearing forests to produce more food. This means interventions at the national-level will be key: this can include a range of solutions including policies such as Brazil’s soy moratorium, the REDD+ programme to compensate for the opportunity costs of preserving these forests, and improvements in agricultural productivity so countries can continue to produce more food on less land. <Chart url="https://ourworldindata.org/grapher/deforestation-co2-trade-by-product?tab=chart&stackMode=absolute®ion=World"/> 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.

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. 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. In 2012 – the mid-year of this period – global [emissions from](https://ourworldindata.org/grapher/global-co2-emissions-fossil-land) fossil fuels, industry and land use change was 40.2 billion tonnes. Deforestation was therefore responsible for [2.6 / 40.2 * 100 = 6.5%]. It estimated that the net change in forests _without _plantations was 121 million hectares. With plantations included – as is standard for the UN’s forest assessments – this was 102 million hectares. The area of Spain is [around](https://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_area) 51 million hectares. Double this area is around 102 million hectares – a little under 110 million hectares. Tyukavina, A., Hansen, M. C., Potapov, P. V., Stehman, S. V., Smith-Rodriguez, K., Okpa, C., & Aguilar, R.

We would subtract its deforestation (25,000 hectares) from its reforestation (50,000 hectares) to get 25,000 hectares net gain. If we sum countries’ [imported deforestation](https://ourworldindata.org/grapher/imported-deforestation) by [World Bank income group](https://ourworldindata.org/grapher/world-banks-income-groups?time=2013&country=IND~IDN), 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%.

The area of India is [around](https://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_area) 330 million hectares. The combined losses in the 1990s and 2000s was 309 million hectares.

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. Notarnicola et al. (2017) estimate that the average EU diet, excluding deforestation, is responsible for 0.5 tonnes CO2 per person. If we add 0.3 tonnes to this figure, deforestation would account for around one-sixth [0.3 / (1.5+0.3) * 100 = 17%]. Notarnicola, B., Tassielli, G., Renzulli, P. A., Castellani, V., & Sala, S.

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.

The data used in this chart comes from several sources. Forests – this data is primarily sourced from the UN Food and Agriculture Organization (FAO). It provides [long-term estimates](https://www.un.org/development/desa/en/news/forest/international-day-forests-2018.html) on forest cover in 10,000 and 5,000 years BP. Its State of the World’s Forests report provides estimates of global forest cover today, and rates of change over previous decades. In a [related post](https://ourworldindata.org/deforestation#global-deforestation-peaked-in-the-1980s-can-we-bring-it-to-an-end) 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. The definition of 'forest' can vary depending on aspects such as tree density and height. Absolute estimates of forest cover from other sources may differ for this reason. However, most align on the relative change in forests over this period. For example, Ellis et al. (2020). estimate a 35% loss of global forest cover since 10,000. This is very close to our estimate of a one-third loss. Agricultural and urban land – The UN [FAO Statistical database](http://www.fao.org/faostat/en/) provides data on global agricultural and urban land from 1961 onwards.

Firstly, international trade does play a role in deforestation \u2014 it\u2019s responsible for almost one-third of emissions. By combining our earlier Sankey diagram and breakdown of emissions by-product, we can see that we can tackle a large share of these emissions through only a few key trade flows. Most traded emissions are embedded in soy and palm oil exports to China and India, as well as beef, soy, and palm oil exports to Europe. The story of both soy and palm oil is complex \u2014 and it\u2019s not obvious that eliminating these products will fix the problem.

This means interventions at the national level will be key: this can include a range of solutions, including policies such as Brazil\u2019s soy moratorium, the REDD+ Programme to compensate for the opportunity costs of preserving these forests, and improvements in agricultural productivity so countries can continue to produce more food on less land.",

## Which countries are gaining, and which are losing forest? Before we look at trends in deforestation across the world specifically, it's useful to understand the _net_ change in forest cover. The net change in forest cover measures any gains in forest cover – either through natural forest expansion or afforestation through tree-planting – minus deforestation. This map shows the net change in forest cover across the world. Countries with a positive change (shown in green) are regrowing forest faster than they're losing it. Countries with a negative change (shown in red) are losing more than they're able to restore. <Chart url="https://ourworldindata.org/grapher/annual-change-forest-area?stackMode=absolute®ion=World"/> <Callout title="A note on UN FAO forestry data"/> ## How much deforestation occurs each year? Net forest loss is not the same as deforestation – it measures deforestation plus any gains in forest over a given period. 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. The UN FAO estimate that 10 million hectares of forest were cut down each year. This interactive map shows deforestation rates across the world. <Chart url="https://ourworldindata.org/grapher/annual-deforestation?stackMode=absolute®ion=World"/> Many people think of environmental concerns as a modern issue: humanity’s destruction of nature and ecosystems as a result of very recent [population growth](http://ourworldindata.org/world-population-growth) and [increasing consumption](http://ourworldindata.org/economic-growth). This is true for some problems, such as climate change. But it’s not the case for deforestation. Humans have been cutting down trees for millennia. How much forest has the world lost? When in history did we lose it? In the chart we see how the cover of the earth’s surface has changed over the past 10,000 years. This is shortly after the end of the last great ice age, through to the present day.2 <Image filename="Global-forest-loss-since-ice-age.png"/> Let’s start at the top. 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. I have therefore excluded these categories so we can focus on how habitable land is used. The bar chart just below shows the earth’s surface cover just after the end of the last ice age.3 10,000 years ago 57% of the world’s habitable land was covered by forest. That’s [6 billion hectares](https://www.un.org/development/desa/en/news/forest/international-day-forests-2018.html). Today, only 4 billion hectares are left. The world has lost one-third of its forest – an area twice the size of the United States. Only 10% of this was lost in the first half of this period, until 5,000 years ago. The global population at this time was small and growing very slowly – there were [fewer than 50 million people](https://ourworldindata.org/grapher/world-population-1750-2015-and-un-projection-until-2100) in the world. The amount of [land per person](https://ourworldindata.org/grapher/total-agricultural-land-use-per-person?time=earliest..2016) that was needed to produce enough food was not small – in fact, it was much larger than today. 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. If we fast-forward to 1700 when the global population [had increased](https://ourworldindata.org/grapher/world-population-1750-2015-and-un-projection-until-2100) more than ten-fold, to 603 million. The amount of land used for agriculture – land to grow crops as well as grazing land for livestock – was expanding. You will notice in the chart that this was not only expanding into previously forested land, but also other land uses such as wild grasslands and shrubbery. Still, more than half of the world’s habitable land was forested. The turn of the 20th century is when global forest loss reached the halfway point: half of total forest loss occurred from 8,000 BC to 1900; the other half occurred in the last century alone. This emphasises two important points. 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. 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. Even with the most basic of lifestyles compared to today’s standards, the per capita footprint of our ancestors would have been large. Low agricultural productivity and a reliance on wood for fuel meant that large amounts of land had to be cleared for basic provisions. Second, it makes clear how much deforestation accelerated over the last century. In just over 100 years the world lost as much forest as it had in the previous 9,000 years. An area the size of the United States. From the chart we see that this was driven by the continued expansion of land for agriculture. When we think of the growing pressures on land from modern populations we often picture sprawling megacities. But urban land accounts for just 1% of global habitable land. Humanity’s biggest footprint is due to what we eat, not where we live. ### How can we put an end to our long history of deforestation? This might paint a bleak picture for the future of the world’s forests: the United Nations projects that the [global population will continue to grow](https://ourworldindata.org/world-population-growth#two-centuries-of-rapid-global-population-growth-will-come-to-an-end), reaching 10.8 billion by 2100. But there are real reasons to believe that this century doesn’t have to replicate the destruction of the last one. 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. Improvements in [crop yields](http://ourworldindata.org/crop-yields) mean the per capita demand for agricultural land continues to fall. We see this in the chart. Since 1961, the amount of land we use for agriculture [increased by only 7%](https://ourworldindata.org/grapher/agricultural-land?tab=chart&stackMode=relative&region=World). Meanwhile, the global [population increased](https://ourworldindata.org/grapher/population?time=1961..2018&country=~OWID_WRL) by 147% – from 3.1 to 7.6 billion.4 This means that agricultural land _per person_ more than halved, from 1.45 to 0.63 hectares. In fact, the world [may have already passed](https://ourworldindata.org/grapher/agricultural-land?tab=chart&stackMode=absolute&region=World) ‘peak agricultural land’ _[we will look at this in more detail in an upcoming post]_. 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. If we can take advantage of these innovations, we can bring deforestation to an end. A future with more people _and_ more forest is possible. <Chart url="https://ourworldindata.org/grapher/agricultural-area-per-capita?tab=chart®ion=World"/> ## Global deforestation peaked in the 1980s. Can we bring it to an end? Since the end of the last great ice age – 10,000 years ago – the world has lost one-third of its forests.5 Two billion hectares of forest – an area twice the size of the United States – has been cleared to grow crops, raise livestock, and use for fuelwood. In a **[previous post](https://ourworldindata.org/deforestation#the-world-has-lost-one-third-of-its-forests-but-an-end-of-deforestation-is-possible)** we looked at this change in global forests over the long-run. What this showed was that although humans have been deforesting the planet for millennia, the rate of forest loss accelerated rapidly in the last few centuries. Half of global forest loss occurred between 8,000BC and 1900; the other half was lost in the last century alone. To understand this more recent loss of forest, let’s zoom in on the last 300 years. The world lost 1.5 billion hectares of forest over that period. That’s an area 1.5-times the size of the United States. In the chart we see the decadal losses and gains in global forest cover. On the horizontal axis we have time, spanning from 1700 to 2020; on the vertical axis we have the decadal change in forest cover. The taller the bar, the larger the change in forest area. This is measured in hectares, which is equivalent to 10,000 m². Forest loss measures the net change in forest cover: the loss in forests due to deforestation plus any expansion of forest through afforestation.6 Unfortunately there is no single source that provides consistent and transparent data on deforestation rates over this period of time. Methodologies change over time, and estimates – especially in earlier periods – are highly uncertain. This means I’ve had to use two separate datasets to show this change over time. As we’ll see, they produce different estimates of deforestation for an overlapping decade – the 1980s – which suggests that these are not directly comparable. I do not recommend combining them into a single series, but the overall trends are still applicable and tell us an important story about deforestation over the last three centuries. The first series of data comes from Williams (2006), who estimates deforestation rates from 1700 to 1995.7 Due to poor data resolution, these are often given as average rates over longer periods – for example, annual average rates are given over the period from 1700 to 1849, and 1920 to 1949. That’s why these rates look strangely consistent over long period of time. The second series comes from the UN Food and Agriculture Organization (FAO). It produces a new assessment of global forests every 5 years.8 <Image filename="global-deforestation-1700s.png"/> The rate and location of forest loss changed a lot. From 1700 to 1850, 19 million hectares were being cleared every decade. That’s around half the size of Germany. It was most temperate forests across Europe and North America that were being lost at this time. Population growth meant that today’s rich countries needed more and more resources such as land for agriculture, wood for energy, and for construction.9 Moving into the 20th century there was a stepwise change in demand for agricultural land and energy from wood. Deforestation rates accelerated. And the hotspot of deforestation changed from the equivalent to the area of South Africa. This increase was mostly driven by tropical deforestation as countries across Asia and Latin America. Global forest loss appears to have reached its peak in the 1980s. The two sources do not agree on the magnitude of this loss: Williams (2006) estimates a loss of 150 million hectares – an area half the size of India – during that decade. Interestingly, the UN FAO 1990 report also estimated that _deforestation_ in tropical ‘developing’ countries was 154 million hectares. But, it estimated that regrowth of old forests offset some of these losses, leading to a net loss of 102 million hectares.10 The latest UN Forest Resources Assessment estimates that the net loss in forests has declined in the last three decades, from 78 million hectares in the 1990s to 47 million hectares in the 2010s. This data maps an expected pathway based on what we know from how human-forest interactions evolve. As we explore in more detail in our **[related article](https://ourworldindata.org/deforestation#forest-transitions-why-do-we-lose-then-regain-forests)**, countries tend to follow a predictable development in forest cover, a U-shaped curve.11 They lose forests as populations grow and demand for agricultural land and fuel increases, but eventually they reach the so-called ‘forest transition point’ where they begin to regrow more forests than they lose. That is what has happened in temperate regions: they have gone through a period of high deforestation rates, before a slowing and reversal of this trend. However, many countries – particularly in the tropics and sub-tropics – are still moving through this transition. Deforestation rates are still very high. --- ### Deforestation rates are still high across the tropics Large areas of forest are still being lost in the tropics today. This is particularly tragic because these are regions with very high concentrations of biodiversity. Let’s look at estimates of deforestation from the latest UN Forest report. This shows us raw deforestation rates, without any adjustment for the regrowth or plantation of forests, which is arguably not as good for ecosystems or carbon storage. This is shown in the chart below. We can see that the UN does estimate that deforestation rates have fallen since the 1990s. However, there was very little progress from the 1990s to 2000s, and an estimated 26% drop in rates in the 2010s. In 2022, the FAO published [a separate assessment](https://www.fao.org/forest-resources-assessment/remote-sensing/fra-2020-remote-sensing-survey/en/) based on Remote Sensing methods; it did not report data for the 1990s, but also estimated a 29% reduction in deforestation rates from early 2000s to the 2010s. <Image filename="global-deforestation-1990s-onwards.png"/> This is progress, but it needs to happen much faster. The world is still losing large amounts of primary forests every year. To put these numbers in context: during the 1990s and first decade of the 2000s, an area almost the size of India was deforested.12 Even with the ‘improved’ rates in the 2010s, this still amounted to an area around twice the size of Spain.13 The regrowth of forests is a positive development. In the chart below, we see how this affects the _net change_ in global forests. Forest recovery and plantation ‘offsets’ a lot of deforestation such that the net losses are around half the rates of deforestation alone. <Image filename="global-deforestation-net-loss.png"/> But we should be cautious here: it’s often not the case that the ‘positives’ of regrowing one hectare of forest offset the ‘losses’ of one hectare of deforestation. Cutting down one hectare of rich, tropical rainforest cannot be completely offset by the plantation of forest in a temperate country. Forest expansion is positive, but does not negate the need to finally end deforestation. 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. But, the fact that forest transitions are possible should give us confidence that a positive future is possible. Many countries have not only ended deforestation, but actually achieved substantial reforestation. It will be possible for our generation to achieve the same on the global scale and bring the 10,000 year history of forest loss to an end. If we want to end deforestation we need to understand where and why it’s happening; where countries are within their transition; and what can be done to accelerate their progress through it. We need to pass the transition point as soon as possible, while minimising the amount of forest we lose along the way. In **[this article](https://ourworldindata.org/what-are-drivers-deforestation)** I look at what’s driving deforestation: that helps us understand what we need to do to solve it. --- ### Forest definitions and comparisons to other datasets There is no universal definition of what a ‘forest’ is. That means there are a range of estimates of forest area, and how this has changed over time. In this article, in the recent period I have used data from the UN’s Global Forest Resources Assessment (2020). The UN carries out these global forest stocktakes every five years. These forest figures are widely-used in research, policy, and international targets, such as in the [Sustainable Development Goals](https://unstats.un.org/sdgs/metadata/files/Metadata-15-01-01.pdf). The UN FAO has a very specific definition of a forest. It’s “land spanning more than 0.5 hectares with trees higher than 0.5 meters and a canopy cover of more than 10%, or trees able to reach these thresholds in situ.” In other words, it has criteria for the area that must be covered (0.5 hectares), the minimum height of trees (0.5 meters) and a density of at least 10%. Compare this to the UN Framework on Climate Change (UNFCCC), which uses forest estimates to calculate land use carbon emissions, and for its REDD+ programme, where low-to-middle income countries can receive finance for verified projects that prevent or reduce deforestation. It [defines a forest](https://www.un-redd.org/glossary/forest) as having a density of 10-30%, a minimum tree height of 2-5 meters, and a smaller area of 0.1 hectares. It’s not just forest definitions that vary between sources. What is measured (and not measured) differs too. [Global Forest Watch](https://www.globalforestwatch.org/) is an interactive online dashboard that tracks ‘tree loss’ and ‘forest loss’ across the world. It measures this in real-time, and can provide better estimates of year-to-year variations in rates of tree loss. However, the UN FAO and Global Forest Watch do not measure the same thing. The UN FAO measures _deforestation_ based on how land is used. It measures the permanent conversion of forested land to another use, such as pasture, croplands, or urbanization. Temporary changes in forest cover, such as losses through wildfire, or small-scale shifting agriculture are not included in deforestation figures, because it is assumed that they will regrow. If the use of land has not changed, it is not considered deforestation. Global Forest Watch (GFW) measures temporary changes in forests. It can detect changes in land _cover_, but does not differentiate the underlying land use. All deforestation would be considered tree loss, but a lot of tree loss would not be considered as deforestation. As GFW describes in its definition of ‘forest loss’: “Loss” indicates the removal or mortality of tree cover and can be due to a variety of factors, including mechanical harvesting, fire, disease, or storm damage. As such, “loss” does not equate to deforestation.” We therefore cannot directly compare these sources. This **[article](https://www.globalforestwatch.org/blog/data-and-research/global-forest-watch-and-the-forest-resources-assessment-explained-in-5-graphics-2/)** from Global Forest Watch gives a good overview of the differences between the UN FAO and GFW methods. Since GFW uses satellite imagery, its methods continually improve. This makes its ability to detect changes in forest cover even stronger. But it also means that comparisons over time are more difficult. It currently warns against comparing pre-2015 and post-2015 data since there was a significant methodological change at that time. Note that this is also a problem in UN FAO reports, as I’ll soon explain. What data from GFW makes clear is that forest loss across the tropics is still very high, and in the last few years, little progress has been made. Since UN FAO reports are only published in 5-year intervals, they miss these shorter-term fluctuations in forest loss. The GFW’s shorter-interval stocktakes of how countries are doing will become increasingly valuable. --- One final point to note is that UN FAO estimates have also changed over time, with improved methods and better access to data. I looked at how net forest loss rates in the 1990s were reported across five UN reports: 2000, 2005, 2010, 2015 and 2020. Estimated rates changed in each successive report: * **[2000 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2000/en/)****:** Net losses of 92 million hectares * **[2005 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2005/en/)****: **89 million hectares * **[2010 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2010/en/)****: **83 million hectares * **[2015 report](https://www.fao.org/forest-resources-assessment/past-assessments/fra-2015/en/)****:** 72 million hectares * **[2020 report](https://www.fao.org/documents/card/en/c/ca9825en)****:** 78 million hectares This should not affect the overall trends reported in the latest report: the UN FAO should – as far as is possible – apply the same methodology to its 1990s, 2000s, and 2010s estimates. However, it does mean we should be cautious about comparing absolute magnitudes across different reports. This is one challenge in presenting 1980 figures in the main visualization in this article. Later reports have not updated 1980 figures, so we have to rely on estimates from earlier reports. We don’t know whether 1980s rates would also be lower with the UN FAO’s most recent adjustments. If so, this would mean the reductions in net forest loss from the 1980s to 1990s were lower than is shown from available data. ## Forest Transitions: why do we lose then regain forests? Globally we deforest around ten million hectares of forest every year.14 That’s an area the size of Portugal every year. Around half of this deforestation is offset by regrowing forests, so overall we lose around five million hectares each year. Nearly all – 95% – of this deforestation [occurs in the tropics](https://ourworldindata.org/deforestation#not-all-forest-loss-is-equal-what-is-the-difference-between-deforestation-and-forest-degradation). But not all of it is to produce products for local markets. 14% of deforestation is driven by consumers in the world’s richest countries – we import beef, vegetable oils, cocoa, coffee and paper that has been produced on deforested land.15 The scale of deforestation today might give us little hope for protecting our diverse forests. But by studying how forests have changed over time, there’s good reason to think that a way forward is possible. ### Many countries have lost then regained forest over millennia 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. 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). I have reconstructed long-term data using various studies which I’ve [documented here](https://docs.google.com/spreadsheets/d/1nYpao4e8Ai-P86jIUZ3r7X6-5MjZ7ZbG7TJQSO729Bg/edit?usp=sharing). Many countries have much less forest today than they did in the past. Nearly half (47%) of France was forested 1000 years ago; today that’s just under one-third (31.4%). The same is true of the United States; back in 1630 46% of the area of today’s USA was covered by forest. Today that’s just 34%. 1000 years ago, 20% of Scotland’s land was covered by forest. By the mid-18th century, only 4% of the country was forested. But then the trend turned, and it moved from deforestation to reforestation. For the last two centuries forests have been growing and are almost back to where they were 1000 years ago.16 <Chart url="https://ourworldindata.org/grapher/forest-area-as-share-of-land-area?tab=chart&time=earliest..latest&country=England~Scotland~FRA~USA®ion=World"/> ### Forest Transitions: the U-shaped curve of forest change What’s surprising is how consistent the pattern of change is across so many countries; as we’ve seen they all seem to follow a ‘U-shaped curve’. They first lose lots of forest, but reach a turning point and begin to regain it again. We can illustrate this through the so-called ‘Forest Transition Model’.17 This is shown in the chart. It breaks the change in forests into four stages, explained by two variables: the amount of forest cover a region has, and the annual _change_ in cover (how quickly it is losing or gaining forest).18 **Stage 1 – The Pre-Transition phase** is defined by having high levels of forest cover _and_ no or only very slow losses over time. Countries may lose some forest each year, but this is at a very slow rate. Mather refers to an annual loss of less than 0.25% as a small loss. **Stage 2 – The Early Transition phase **is when countries start to lose forests very rapidly. Forest cover falls quickly, and the annual loss of forest is high. **Stage 3 – The Late Transition phase **is when deforestation rates start to slow down again. At this stage, countries are still losing forest each year but at a lower rate than before. At the end of this stage, countries are approaching the ‘transition point’. **Stage 4 – The Post-Transition phase **is when countries have passed the ‘transition point’ and are now gaining forest again. At the beginning of this phase, the forest area is at its lowest point. But forest cover increases through reforestation. The annual change is now positive. <Image filename="Forest-Transition-Model-01.png"/> ### Why do countries lose then regain forest? Many countries have followed this classic U-shaped pattern. What explains this? There are two reasons that we cut down forests: * **Forest resources:** we want the resources that they provide – the wood for fuel, building materials, or paper; * **Land:** – we want to use the land they occupy for something else – farmland to grow crops; pasture to raise livestock; or land to build roads and cities. Our demand for both of these initially increases as [populations grow](http://ourworldindata.org/world-population-growth) and poor [people get richer](http://ourworldindata.org/economic-growth). We need more fuelwood to cook, more houses to live in, and importantly, more food to eat. But, as countries continue to get richer this demand slows. The rate of population growth tends to slow down. Instead of using wood for fuel we switch to [fossil fuels](http://ourworldindata.org/fossil-fuels), or hopefully, more [renewables](http://ourworldindata.org/renewable-energy) and [nuclear energy](http://ourworldindata.org/nuclear-energy). Our [crop yields](http://ourworldindata.org/crop-yields) improve and so we need less land for agriculture. This demand for resources and land is not always driven by domestic markets. As I mentioned earlier, 14% of deforestation today is driven by consumers in rich countries. The Forest Transition therefore tends to follow a ‘development’ pathway.19 As a country achieves economic growth it moves through each of the four stages. This explains historical trends we see for countries across the world today. Rich countries – such as the USA, France and the United Kingdom – have had a long history of deforestation but are now passed the transition point. Most deforestation today occurs in low-to-middle income countries. ### Where are countries in the transition today? 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. Most of our future deforestation is going to come from countries in the pre- or early-transition phase. Several studies have assessed the stage of countries across the world.20 The most recent analysis to date was published by Florence Pendrill and colleagues (2019) which looked at each country’s stage in the transition, the drivers of deforestation but also the role of international trade.21 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. In the map we see their assessment of each country’s stage in the transition. Most of today’s richest countries – all of Europe, North America, Japan, South Korea – have passed the turning point and are now regaining forest. This is also true for major economies such as China and India. That these countries have recently regained forests is also visible in the long-term forest trends above. Across sub-tropical countries we have a mix: many upper-middle income countries are now in the late transition phase. 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. Countries such as Indonesia, Myanmar, and the Democratic Republic of Congo are in the early transition phase and are losing forests quickly. Some of the world’s poorest countries are still in the pre-transition phase. 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. <Chart url="https://ourworldindata.org/grapher/forest-transition-phase?stackMode=absolute®ion=World"/> ## Not all forest loss is equal: what is the difference between deforestation and forest degradation? 15 billion trees are cut down every year.22 The [Global Forest Watch](https://www.globalforestwatch.org/dashboards/global/) project – using satellite imagery – estimates that global tree loss in 2019 was 24 million hectares. That’s an area the size of the United Kingdom. These are big numbers, and important ones to track: forest loss creates a number of negative impacts, ranging from carbon emissions to species extinctions and biodiversity loss. But distilling changes to this single metric – tree or forest loss – comes with its own issues. The problem is that it treats all forest loss as equal. It assumes the impact of clearing primary rainforest in the Amazon to produce soybeans is the same as logging planted forests in the UK. The latter will experience short-term environmental impacts, but will ultimately regrow. When we cut down primary rainforest we are transforming this ecosystem forever. When we treat these impacts equally we make it difficult to prioritize our efforts in the fight against deforestation. Decisionmakers could give as much of our attention to European logging as to destruction of the Amazon. As we will see later, this would be a distraction from our primary concern: ending tropical deforestation. The other issue that arises is that ‘tree loss’ or ‘forest loss’ data collected by satellite imagery often doesn’t match the official statistics reported by governments in their land use inventories. This is because the latter only captures _deforestation_ – the replacement of forest with another land use (such as cropland). It doesn’t capture trees that are cut down in planted forests; the land is still forested, it’s now just regrowing forest. 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. ### Understanding and seeing the drivers of forest loss ‘Forest loss’ or ‘tree loss’ captures two fundamental impacts on forest cover: _deforestation_ and _forest degradation_. **_Deforestation_** is the complete removal of trees for the conversion of forest to another land use such as agriculture, mining, or towns and cities. It results in a permanent conversion of forest into an alternative land use. The trees are _not expected to regrow_. **_Forest degradation_** measures a thinning of the canopy – a reduction in the density of trees in the area – but without a change in land use. The changes to the forest are often temporary and it’s expected that they will regrow. From this understanding we can define five reasons why we lose forests: * **Commodity-driven deforestation** is the long-term, permanent conversion of forests to other land uses such as agriculture (including oil palm and cattle ranching), mining, or energy infrastructure. * **Urbanization** is the long-term, permanent conversion of forests to towns, cities and urban infrastructure such as roads. * **Shifting agriculture** is the small to medium-scale conversion of forest for farming, that is later abandoned so that forests regrow. This is common of local, subsistence farming systems where populations will clear forest, use it to grow crops, then move on to another plot of land. * **Forestry production** is the logging of managed, planted forests for products such as timber, paper and pulp. These forests are logged periodically and allowed to regrow. * **Wildfires** destroy forests temporarily. When the land is not converted to a new use afterwards forests can regrow in the following years. Thanks to satellite imagery, we can get a birds-eye view of what these drivers look like from above. In the figure we see visual examples from the study of forest loss classification by Philip Curtis et al. (2018), published in _Science_.23 <Image filename="Identifying-drivers-of-forest-loss.png"/> 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. The change is permanent. There is little forest left. Forestry production and wildfires usually result in _forest degradation_ – the forest experiences short-term disturbance but if left alone is likely to regrow. The change is temporary. This is nearly always true of planted forests in temperate regions – there, planted forests are long-established and do not replace primary existing forests. 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 'Shifting agriculture’ is usually classified as degradation because the land is often abandoned and the forests regrow naturally. But it can bridge between deforestation and degradation depending on the timeframe and permanence of these agricultural practices. ### One-quarter of forest loss comes from tropical deforestation We’ve seen the five key drivers of forest loss. Let’s put some numbers to them. In their analysis of global forest loss, Philip Curtis and colleagues used satellite images to assess where and why the world lost forests between 2001 and 2015. The breakdown of forest loss globally, and by region, is shown in the chart.23 Just over one-quarter of global forest loss is driven by deforestation. 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%). We see massive differences in how important each driver is across the world. 95% of the world’s deforestation occurs in the tropics [we look at this breakdown again later]. 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. In contrast, most forest degradation – two-thirds of it – occurs in temperate countries. 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](https://ourworldindata.org/deforestation#global-deforestation-peaked-in-the-1980s-can-we-bring-it-to-an-end)_****_]_**. They cut down their forests and replaced it with agricultural land long ago. 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. Africa is also different here. Forests are mainly cut and burned to make space for local, subsistence agriculture or for fuelwood for energy. 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. <Image filename="Forest-loss-by-driver-and-region.png"/> Africa is also an outlier as a result of how many people still rely on wood as their primary energy source. Noriko Hosonuma et al. (2010) looked at the primary drivers of deforestation and degradation across tropical and subtropical countries specifically.24 The breakdown of forest degradation drivers is shown in the following chart. Note that in this study, the category of subsistence agriculture was classified as a _deforestation_ driver, and so is not included. In Latin America and Asia the dominant driver of _degradation_ was logging for products such as timber, paper and pulp – this accounted for more than 70%. Across Africa, fuelwood and charcoal played a much larger role – it accounted for more than half (52%). This highlights an important point: [less than 20%](https://ourworldindata.org/grapher/access-to-clean-fuels-and-technologies-for-cooking?tab=chart&time=earliest..latest&country=~Sub-Saharan%20Africa) of people in Sub-Saharan Africa have access to clean fuels for cooking, meaning they still rely on wood and charcoal. 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. This follows the classic ‘forest transition’ model with development, which we look at in more detail in a **[related article](https://ourworldindata.org/deforestation#forest-transitions-why-do-we-lose-then-regain-forests)**. <Image filename="Drivers-of-forest-degradation.png"/> ### Tropical deforestation should be our primary concern The world loses almost six million hectares of forest each year to deforestation. That’s like losing an area the size of Portugal every two years. 95% of this occurs in the tropics. The breakdown of deforestation by region is shown in the chart. 59% occurs in Latin America, with a further 28% from Southeast Asia. In a **[related article](https://ourworldindata.org/drivers-of-deforestation)** we look in much more detail at what agricultural products, and which countries are driving this. As we saw previously, this deforestation accounts for around one-quarter of global forest loss. 27% of forest loss results from ‘commodity-driven deforestation’ – cutting down forests to grow crops such as soy, palm oil, cocoa, to raise livestock on pasture, and mining operations. Urbanization, the other driver of deforestation accounts for just 0.6%. It’s the foods and products we buy, not where we live, that has the biggest impact on global land use. It might seem odd to argue that we should focus our efforts on tackling this quarter of forest loss (rather than the other 73%). But there is good reason to make this our primary concern. Philipp Curtis and colleagues make this point clear. At their [Global Forest Watch](https://www.globalforestwatch.org/) platform they were already presenting maps of forest loss across the world. But they wanted to contribute to a more informed discussion about where to focus forest conservation efforts by understanding _why_ forests were being lost. To quote them, they wanted to prevent “a common misperception that any tree cover loss shown on the map represents deforestation”. And to “identify where deforestation is occurring; perhaps as important, show where forest loss is not deforestation”. Why should we care most about tropical deforestation? There is a geographical argument (why the tropics?) and an argument for why deforestation is worse than degradation. Tropical forests are home to some of the richest and most diverse ecosystems on the planet. Over half of the world’s species reside in tropical forests.25 Endemic species are those which only naturally occur in a single country. Whether we look at the distribution of endemic [mammal species](https://ourworldindata.org/grapher/endemic-mammal-species-by-country), [bird species](https://ourworldindata.org/grapher/endemic-bird-species-by-country), or [amphibian species](https://ourworldindata.org/grapher/endemic-amphibian-species-by-country), the map is the same: subtropical countries are packed with unique wildlife. Habitat loss is the leading driver of global biodiversity loss.26 When we cut down rainforests we are destroying the habitats of many unique species, and reshaping these ecosystems permanently. Tropical forests are also large carbon sinks, and can store a lot of carbon per unit area.27 Deforestation also results in larger losses of biodiversity and carbon relative to degradation. 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. But the magnitude of these impacts are often less than the complete conversion of forest. They are smaller, and more temporary. When deforestation happens, almost all of the carbon stored in the trees and vegetation – called the ‘aboveground carbon loss’ – is lost. Estimates vary, but on average only 10-20% of carbon is lost during logging, and 10-30% from fires.28 In a study of logging practices in the Amazon and Congo, forests retained 76% of their carbon stocks shortly after logging.29 Logged forests recover their carbon over time, as long as the land is not converted to other uses (which is what happens in the case of deforestation). Deforestation tends to occur on forests that have been around for centuries, if not millennia. Cutting them down disrupts or destroys established, species-rich ecosystems. The biodiversity of managed tree plantations which are periodically cut, regrown, cut again, then regrown is not the same. That is why we should be focusing on tropical deforestation. Since agriculture is responsible for 60 to 80% of it, what we eat, where it’s sourced from, and how it is produced is our strongest lever to bring deforestation to an end. <Image filename="Forest-loss-by-driver.png"/> ## Do rich countries import deforestation from overseas? There is a marked divide in the state of the world’s forests. In most rich countries, across Europe, North America and East Asia, [forest cover is increasing](https://ourworldindata.org/grapher/change-forest-vs-gdp?tab=chart&stackMode=absolute&country=&region=World), whilst in many low-to-middle income countries it’s decreasing. But, it would be wrong to think that the only impact rich countries have on global forests is through changes in their domestic forests. They also contribute to global deforestation through the foods they import from poorer countries. Today, most deforestation occurs in the tropics. 71% of this is driven by demand in domestic markets, and the remaining 29% for the production of products that are traded. 40% of traded deforestation ends up in high-income countries, meaning they are responsible for 12% of deforestation.30 Let’s take a look at which countries are causing deforestation overseas and the size of this impact. ### Which countries are causing deforestation overseas? How much do people in rich countries contribute to deforestation overseas? To investigate this question, researchers Florence Pendrill et al. (2019) quantified the deforestation embedded in traded goods between countries.21 They did this by calculating the amount of deforestation associated with specific food and forestry products, and combining it with a trade model. In the map we see the _net_ deforestation embedded in trade for each country. This is calculated by taking each country’s _imported_ deforestation and subtracting its _exported_ deforestation. Net importers of deforestation (shown in brown) are countries that contribute more to deforestation in other countries than they do in their home country. The consumption choices of people in these countries cause deforestation elsewhere in the world. <Chart url="https://ourworldindata.org/grapher/net-deforestation-in-trade?stackMode=absolute®ion=World"/> For example, after we adjust for all the goods that the UK imports and exports, it caused more deforestation elsewhere than it did domestically. It was a net importer. Brazil, in contrast, caused more deforestation domestically in the production of goods for other countries than it imported from elsewhere. It was a net exporter. 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. they’re driving deforestation elsewhere; whilst many subtropical countries are partly cutting down trees to meet this demand from rich countries. Most deforestation occurs for the production of goods that are consumed within domestic markets. 71% of deforestation is for domestic production. Less than one-third (29%) is for the production of goods that are traded. High-income countries were the largest 'importers' of deforestation, accounting for 40% of it. This means they were responsible for 12% of global deforestation.31 It is therefore true that rich countries are causing deforestation in poorer countries. ### Are countries importing more deforestation than they’re regrowing domestically? Many rich countries are driving deforestation in other parts of the world, but are regrowing forests domestically. 79% of exported deforestation ended up in those countries that had stopped losing domestic forests. How do these two measures compare? Are they causing more deforestation elsewhere than they are regenerating in forests at home? Let’s take an example. 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. 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. Not all forest is equal. Tropical forests are often more productive than temperate forests, meaning they store more carbon. They are also richer sites of biodiversity. And, we might place more value on preserving primary, native forests that haven’t yet been deforested over regrowing forests that have lost their previous ecosystems. Hence, we should keep in mind that forest area is not the only aspect that matters – where that forest is and how rich in life it is matters too. It would be good if there was data available that would capture these additional aspects. We manage to capture some of these differences in carbon in our related article on **[deforestation ](https://ourworldindata.org/deforestation#carbon-emissions-from-deforestation-are-they-driven-by-domestic-demand-or-international-trade)****_[emissions](https://ourworldindata.org/deforestation#carbon-emissions-from-deforestation-are-they-driven-by-domestic-demand-or-international-trade)_**** [embedded in trade](https://ourworldindata.org/deforestation#carbon-emissions-from-deforestation-are-they-driven-by-domestic-demand-or-international-trade)**. Without reliable metrics that capture all of these differences, we will have to stick with total changes in forest area for now. But we should keep these important aspects in mind when comparing forest losses and gains. 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. Since there is often year-to-year variability in deforestation or reforestation rates, this is shown as the five-year average. On the x-axis we have imported deforestation. The grey line marks where the area of domestic regrowth of forests is exactly equal to imported deforestation. Countries that lie along this line would have a net-neutral impact on global forests: the area they are causing to deforestation overseas is exactly as large as the area they are regrowing at home. <Chart url="https://ourworldindata.org/grapher/domestic-forest-change-vs-imported-deforestation?tab=chart&stackMode=absolute&country=®ion=World"/> 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. For example, the US ‘imported’ 64,000 hectares of deforested land, but increased its domestic forest area by 275,000 hectares. More than four times as much. On balance, they add to the global forest stock. Countries below the line – such as the UK and Germany – are not growing forests fast enough to offset the deforestation they’re creating elsewhere. The UK ‘imported’ 34,000 hectares of deforestation but increased its domestic forests by only 19,000 hectares. These countries might have high levels of afforestation at home, but they’re still having a net negative impact on the size of the world’s forests. ### Rich countries need to be more conscious of how they’re contributing to global deforestation After seeing this data, people might argue that we should cut back on trade. If poorer countries are cutting down forests to make food for rich consumers, then we should just stop trading these goods. But the solution is not so simple. There are other aspects to consider. International trade is important for socioeconomic development. Many farmers rely on international buyers to earn a living and improve their livelihoods. Not only would this be bad for people, it might also be bad for forests. One of the reasons poorer countries clear forest to make room for farmland is that they achieve low [crop yields](http://ourworldindata.org/crop-yields). If you struggle to increase crop yields but want to produce more food, then expanding your agricultural land is the only option. This often comes at the cost of forests. Improvements in agricultural productivity tends to both drive and follow [economic growth](http://ourworldindata.org/economic-growth). 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. So, what can we do? 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. 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. That’s both an economic and environmental win. The first step in doing this is for rich countries to monitor their deforestation impacts overseas more closely. They should keep their domestic reforestation targets in perspective with their net impact on global forests. Sometimes these restoration programmes pale in comparison to the deforestation they’re driving elsewhere. ## Carbon emissions from deforestation: are they driven by domestic demand or international trade? 95% of global deforestation occurs in the tropics. Brazil and Indonesia alone account for almost half. After long periods of forest clearance in the past, most of today’s richest countries are increasing tree cover through afforestation. This might put the responsibility for ending deforestation solely on tropical countries. But, supply chains are international. What if this deforestation is being driven by consumers elsewhere? Many consumers are concerned that their food choices are linked to deforestation in some of these hotspots. Since three-quarters of tropical deforestation is driven by agriculture, that’s a valid concern. It feeds into the popular idea that ‘eating local’ is one of the best ways to reduce your carbon footprint. In a **[previous article](https://ourworldindata.org/food-choice-vs-eating-local)** I showed that the types of food you eat matter _much_ more for your carbon footprint than where it comes from – this is because transport usually makes up a small percentage of your food’s emissions, even if it comes from the other side of the world. If you want to reduce your carbon footprint, reducing meat and dairy intake – particularly beef and lamb – has the largest impact. But, understanding the role of deforestation in the products we buy is important. If we can identify the producer countries, importing countries, and specific products responsible, we can direct our efforts towards interventions that will really make a difference. ## One-third of CO2 emissions from deforestation are embedded in international trade 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. That was 6.5% of global CO2 emissions.35 International trade was responsible for around one-third (29%) of these emissions. This is probably less than many people would expect. Most emissions – 71% – came from foods consumed in the country that they were produced. It’s domestic demand, not international trade, that is the main driver of deforestation. In the chart we see how emissions from tropical deforestation are distributed through international supply chains. 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 paths between these end boxes indicate where emissions are being traded – the wider the bar, the more emissions are embedded in these products. Latin America exports around 23% of its emissions; that means more than three-quarters are generated for products that are consumed within domestic markets. The Asia-Pacific region – predominantly Indonesia and Malaysia – export a higher share: 44%. As we will see later, this is dominated by palm oil exports to Europe, China, India, North America and the Middle East. Deforestation in Africa is mainly driven by local populations and markets; only 9% of its emissions are exported. Since international demand is driving one-third of deforestation emissions, we have some opportunity to reduce emissions through global consumers and supply chains. But most emissions are driven by domestic markets – this means policies in the major producer countries will be key to tackling this problem. <Image filename="Deforestation-emissions-in-trade-–-Sankey-01.png"/> ## How much deforestation emissions is each country responsible for? Let’s now focus on the consumers of products driving deforestation. After we adjust for imports and exports, how much CO2 from deforestation is each country responsible for? Rather than looking at total figures by country [if you’re interested, we have mapped them **[here](https://ourworldindata.org/grapher/co2-deforestation-for-food?stackMode=absolute&region=World)**] we have calculated the per capita footprint. This gives us an indication of the impact of the average person’s diet. Note that this only measures the emissions from tropical deforestation – it doesn’t include any other emissions from agricultural production, such as methane from livestock, or rice, or the use of fertilizers. In the chart we see deforestation emissions per person, measured in tonnes of CO2 per year. For example, the average German generated half a tonne (510 kilograms) of CO2 per person from domestic and imported foods. At the top of the list we see some of the major _producer_ countries – Brazil and Indonesia. The fact that the per capita emissions _after_ trade are very high means that a lot of their food products are consumed by people in Brazil and Indonesia. The diet of the average Brazilian creates 2.7 tonnes of CO2 from deforestation alone. That’s more than the country’s CO2 [emissions from fossil fuels](https://ourworldindata.org/explorers/co2?tab=chart&xScale=linear&yScale=linear&stackMode=absolute&endpointsOnly=0&time=earliest..latest&country=China~United%20States~India~United%20Kingdom~World&region=World&Gas%20=CO%E2%82%82&Accounting%20=Production-based&Fuel%20=Total&Count%20=Per%20capita&Relative%20to%20world%20total%20=), which are around 2.2 tonnes per person. But we also see that some countries which import a lot of food have high emissions. Luxembourg has the largest footprint at nearly three tonnes per person. Imported emissions are also high for Taiwan, Belgium and the Netherlands at around one tonne. The average across the EU was 0.3 tonnes CO2 per person. To put this in perspective, that would be around one-sixth of the total carbon footprint of the average EU diet.36 <Chart url="https://ourworldindata.org/grapher/per-capita-co2-food-deforestation?tab=chart&stackMode=absolute&time=earliest..latest®ion=World"/> ## Beef, soybeans and palm oil are the key drivers of deforestation We know where deforestation emissions are occurring, and where this demand is coming from. But we also need to know what products are driving this. This helps consumers understand what products they should be concerned about, but also allows us to target specific supply chains. As we covered in a **[previous article](https://ourworldindata.org/drivers-of-deforestation)**, 60% of tropical deforestation is driven by beef, soybean and palm oil production. We should not only look at where these foods are produced, but also where the consumer demand is coming from. In the chart here we see the breakdown of deforestation emissions by product for each consumer country. The default is shown for Brazil, but you can explore the data for a range of countries using the “Change country” button. We see very clearly that the large Brazilian footprint is driven by its domestic demand for beef. 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. Across the US and Europe the breakdown of products is more varied. But, overall, oilseeds and beef tend to top the list for most countries. Bringing all of these elements together, we can focus on a few points that should help us prioritise our efforts to end deforestation. Firstly, international trade does play a role in deforestation – it’s responsible for almost one-third of emissions. By combining our earlier Sankey diagram, and breakdown of emissions by product, we can see that we can tackle a large share of these emissions through only a few key trade flows. Most traded emissions are embedded in soy and palm oil exports to China and India; and beef, soy and palm oil exports to Europe. The story of both soy and palm oil are complex – and it’s not obvious that eliminating these products will fix the problem. We therefore look at them both individually in more detail, to better understand what we can do about it. But international markets alone cannot fix this problem. Most tropical deforestation is driven by demand for products in domestic markets. Brazil’s emissions are high because Brazilians eat a lot of beef. Africa’s emissions are high because people are clearing forests to produce more food. This means interventions at the national-level will be key: this can include a range of solutions including policies such as Brazil’s soy moratorium, the REDD+ programme to compensate for the opportunity costs of preserving these forests, and improvements in agricultural productivity so countries can continue to produce more food on less land. <Chart url="https://ourworldindata.org/grapher/deforestation-co2-trade-by-product?tab=chart&stackMode=absolute®ion=World"/> Estimates vary, but most date the end of the last great ice age to around 11,700 years ago.Kump, L.

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. 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. In 2012 – the mid-year of this period – global [emissions from](https://ourworldindata.org/grapher/global-co2-emissions-fossil-land) fossil fuels, industry and land use change was 40.2 billion tonnes. Deforestation was therefore responsible for [2.6 / 40.2 * 100 = 6.5%]. It estimated that the net change in forests _without _plantations was 121 million hectares. With plantations included – as is standard for the UN’s forest assessments – this was 102 million hectares. The area of Spain is [around](https://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_area) 51 million hectares. Double this area is around 102 million hectares – a little under 110 million hectares. Tyukavina, A., Hansen, M. C., Potapov, P. V., Stehman, S. V., Smith-Rodriguez, K., Okpa, C., & Aguilar, R.

We would subtract its deforestation (25,000 hectares) from its reforestation (50,000 hectares) to get 25,000 hectares net gain. If we sum countries’ [imported deforestation](https://ourworldindata.org/grapher/imported-deforestation) by [World Bank income group](https://ourworldindata.org/grapher/world-banks-income-groups?time=2013&country=IND~IDN), 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%.

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. Notarnicola et al. (2017) estimate that the average EU diet, excluding deforestation, is responsible for 0.5 tonnes CO2 per person. If we add 0.3 tonnes to this figure, deforestation would account for around one-sixth [0.3 / (1.5+0.3) * 100 = 17%]. Notarnicola, B., Tassielli, G., Renzulli, P. A., Castellani, V., & Sala, S.

The data used in this chart comes from several sources. **Forests –** this data is primarily sourced from the UN Food and Agriculture Organization (FAO). It provides [long-term estimates](https://www.un.org/development/desa/en/news/forest/international-day-forests-2018.html) on forest cover in 10,000 and 5,000 years BP. Its State of the World’s Forests report provides estimates of global forest cover today, and rates of change over previous decades. In a **[related post](https://ourworldindata.org/deforestation#global-deforestation-peaked-in-the-1980s-can-we-bring-it-to-an-end)** 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. The definition of 'forest' can vary depending on aspects such as tree density and height. Absolute estimates of forest cover from other sources may differ for this reason. However, most align on the relative change in forests over this period. For example, Ellis et al. (2020). estimate a 35% loss of global forest cover since 10,000. This is very close to our estimate of a one-third loss. **Agricultural and urban land – **The UN [FAO Statistical database](http://www.fao.org/faostat/en/) provides data on global agricultural and urban land from 1961 onwards.
