- Cattle, oil palm, soy, cocoa, rubber, coffee and plantation wood fiber replaced 71.9 million hectares of forest, an area of land over twice the size of Germany.
- At 45.1 million hectares, cattle pasture replaced the most forest by far.
How do you explain farming can cause deforestation?
Trees, and plants in general, affect the water cycle significantly:
- their canopies intercept a proportion of precipitation, which is then evaporated back to the atmosphere ( canopy interception );
- their litter, stems and trunks slow down surface runoff;
- their roots create macropores – large conduits – in the soil that increase infiltration of water;

How many trees are lost a year due to deforestation?
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.
How does agriculture impact our ecosystems?
Agriculture can have a massive impact on the ecosystems surrounding it. This environmental impact of agriculture is the effect of various farming practices, and it can vary greatly depending on the country we are looking at. Many critical environmental issues are tied to agriculture, such as climate change, dead zones, genetic engineering …
Which type of agriculture is responsible for deforestation?
Every year, industrial agriculture is contributing to deforestation in over five million hectares of forest lands, a new analysis has shown. Despite attempts made to reduce deforestation, the amount of forest land taken over by industrially valuable crops, like palm oil trees, has remained steady from 2001 to 2015.
How does agriculture affect rainforests?
Agriculture is the second main cause of forest conversion in the Amazon. In addition to deforestation, agricultural practices tend to cause significant soil erosion and river siltation, as well as aquatic contamination with agrochemicals. Agriculture in the Amazon is extremely diverse.
How does agriculture affect the environment?
Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
How much does animal agriculture contribute to deforestation?
Beef production is responsible for 41% of deforestation; palm oil and soybeans account for another 18%; and logging for paper and wood across the tropics, another 13%.
What is the biggest cause of forest loss?
The biggest cause of forest loss – accounting for around 70 per cent – is agricultural deforestation, notably for beef, soy, palm oil and commercial timber. Soy ranks as the second largest agricultural driver of deforestation after cattle products.
Why is the EU involved in the production of soy?
The EU is involved mainly because European farmers rely on imported soy from Brazil, Argentina and Paraguay to use as animal feed. Of all the soy meal consumed in the EU, 83 per cent goes in concentrate feed for pigs and poultry.
Why is deforestation a problem?
Deforestation has long been fueled by poor governance. This manifests as illegal activity, corruption, unclear or inequitable land tenure, and conflicting authority over forest resources particularly evident now in the Amazon crisis where indigenous land custodians are having their land rights eroded.
What are the main components of deforestation?
Recognizing the role that commodity production—palm oil, soy, timber, and beef, but also cocoa and coffee – plays in deforestation, companies and producers must identify and eliminate deforestation from supply chains. That means working with companies and farmers to adopt better practices and increase productivity, thus preventing further deforestation.
How do shade trees affect coffee plants?
Shade trees can increase the water and nutrient holding-potential of the soil, and their fallen leaves create organic matter in the soil.
Why did the Amazon fires happen?
These fires, set to clear land for crops, sent vast swaths of the Amazon up in smoke – not only harming local people and wildlife, but destroying critical carbon sinks that the world needs to help slow climate change. It’s an all-too-common pattern seen across the tropics: to make room for crops, forests come down.
What is certification in agriculture?
Certification offers just that, a system whereby producers are encouraged to use more sustainable methods.
Is agroforestry a solution?
Agroforestry is a powerful solution, even though it is not appropriate everywhere. And there are a lot of examples where it is benefitting the landscape compared to traditional forms of agriculture for example, in cocoa-growing Cote d’Ivoire and Ghana where shade trees are now promoted.
What is deforestation linked to?
Deforestation Linked to Agriculture. This indicator aims to monitor the role of specific commodities—namely, cattle, oil palm, soy, cocoa, rubber, coffee, and wood fiber—in deforestation. Glossary The change from forest to another land cover or land use, such as forest to plantation or forest to urban area. linked to agriculture.
How does soy contribute to deforestation?
Although the rate at which forests were replaced by soy has declined substantially since the turn of the century, research suggests that soy contributes indirectly to large areas of deforestation in the Amazon. 20 Several studies have documented an increase in soy planting on former pasture areas in Mato Grosso and the Amazon, potentially leading to a displacement of pasture that may, in turn, result in further deforestation. The analysis presented here provides a snapshot of both direct and indirect conversion of forests to soy since 2000. The analysis can also be constrained to direct conversion by looking only at those areas that were deforested within three years of the establishment of soy. Around half, or 3.9 Mha, of forest area replaced by soy represents direct conversion of forests. Focusing on direct conversion for soy also reveals different dynamics in the Brazilian Amazon and the Cerrado. In the Brazilian Cerrado, 58 percent of forest replacement by soy is direct, whereas in the Brazilian Amazon only 39 percent is direct.
How long did deforestation occur before oil palms were planted?
To better assess forest areas that were cleared and more immediately planted with oil palm, the analysis can be constrained to identify areas in which deforestation occurred during the four years prior to the establishment of the oil palm plantation.
How many acres are in a hectare?
Glossary One hectare equals 100 square meters, 2.47 acres, or 0.01 square kilometers and is about the size of a rugby field. A football pitch is slightly smaller than a hectare (pitches are between 0.62 and 0.82 hectares). of land deforested between 2001 and 2015 in each of these jurisdictions.
What percentage of Brazil’s forest is replaced by cattle?
The Amazon accounted for 70 percent of forest area replaced by cattle in Brazil, with an additional 20 percent occurring in the Cerrado. GFR #56 – Forest area replaced by cattle by Brazil Biome. -.
Does loss equate to deforestation?
As such, loss does not equate to deforestation. , this indicator shows where previously forested lands have been replaced by agriculture. Critically, this does not necessarily imply that current-day farms or pastures were directly responsible for past deforestation events.
How does deforestation affect biodiversity?
Deforestation also threatens the world’s biodiversity. Tropical forests are home to great numbers of animal and plant species. When forests are logged or burned, it can drive many of those species into extinction. Some scientists say we are already in the midst of a mass-extinction episode.
How does slash and burn agriculture help deforestation?
With this agricultural method, farmers burn large swaths of forest, allowing the ash to fertilize the land for crops.
Why do tropical forests have carbon dioxide?
That is because trees take in carbon dioxide from the air for photosynthesis, and carbon is locked chemically in their wood.
What happens when trees are burned?
When trees are burned, this carbon returns to the atmosphere as carbon dioxide. With fewer trees around to take in the carbon dioxide, this greenhouse gas accumulates in the atmosphere and accelerates global warming. Deforestation also threatens the world’s biodiversity.
Why are forests razed?
Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Deforestation has greatly altered landscapes around the world. About 2,000 years ago, 80 percent of Western Europe was forested; today the figure is 34 percent.
What is the meaning of “deforestation”?
deforestation. Noun. destruction or removal of forests and their undergrowth. erosion. Noun. act in which earth is worn away, often by water, wind, or ice. mass extinction. Noun. extinction event in which a large number of species go extinct in a relatively short period of time.
What percentage of Europe was forested?
About 2,000 years ago, 80 percent of Western Europe was forested; today the figure is 34 percent . In North America, about half of the forests in the eastern part of the continent were cut down from the 1600s to the 1870s for timber and agriculture.
What causes the most deforestation in the world?
Agriculture causes 80% of tropical deforestation. Deforestation for oil palm plantations in Borneo. Photo by Rhett A. Butler. Agriculture is the direct driver of roughly 80 percent of tropical deforestation, while logging is the biggest single driver of forest degradation, says a new report funded by the British and Norwegian governments.
What are the drivers of deforestation?
Drivers of Deforestation and Forest Degradation notes that industrial activities are the principal driver of deforestation and degradation worldwide, but subsistence agriculture and fuelwood consumption remains an important direct driver of deforestation, especially in Africa. Drivers vary on a regional scale.
Will the pressure on forests continue?
While pressure on forests will continue as the world globalizes and consumption and human population grow, the report does see signs of hope for the planet’s forests. “There are promising strategies to decouple economic growth from deforestation,” the report states.
What is the main cause of deforestation?
Some 80% of global deforestation is a result of agricultural production, which is also the leading cause of habitat destruction. Animal agriculture — livestock and animal feed is a significant driver of deforestation, and is also responsible for approximately 60% of direct global greenhouse gas (GHG) emissions.
What is the biggest cause of deforestation in Amazon?
Cattle ranching — and the soy farming needed to feed the cattle — is the biggest cause of deforestation in virtually every Amazon country. Around 90% of soy is used to feed animals to produce meat and dairy products.
How much carbon is released from cattle ranching?
Worldwide, deforestation due to cattle ranching releases 340 million tons of carbon into the atmosphere each year, or 3.4 percent of global greenhouse gas emissions. Most of this comes from the Amazon region. In 2009, Greenpeace published a landmark three-year investigation entitled Slaughtering the Amazon.
What percentage of deforestation is caused by animal agriculture?
One of the leading causes of deforestation globally is animal agriculture, which is why a plant-based diet can help. Today, nearly 70% of cleared lands in the Amazon, the largest remaining tropical rainforest in the world, are used as cattle pastures.
How does animal agriculture cause deforestation?
How Does Animal Agriculture Cause Deforestation? As the global demand for meat rises, so does the number of cattle needed to produce beef. These animals require space and nourishment, so millions of acres of uncultivated land are cleared every year to make room for feed crops and grazing pastures.
How much does agriculture contribute to deforestation?
Agriculture is the direct driver of roughly 80 percent of tropical deforestation, while logging is the biggest single driver of forest degradation, says a new report funded by the British and Norwegian governments.
How much does livestock farming account for deforestation?
Habitat conversion, commonly referred to as deforestation, lies at the crux of what is shaping the future of the Amazon Biome. Extensive cattle ranching is the number one culprit of deforestation in virtually every Amazon country, and it accounts for 80% of current deforestation (Nepstad et al.
Which type of farming causes more deforestation?
In agriculture, Subsistence farming is responsible for 48% of deforestation and commercial farming is responsible for 32%.
What is the biggest contributor to deforestation?
Beef production is the top driver of deforestation in the world’s tropical forests. The forest conversion it generates more than doubles that generated by the production of soy, palm oil, and wood products (the second, third, and fourth biggest drivers) combined.
What are the 5 effects of deforestation?
The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
How long will the rainforests disappear?
National Geographic says that at the current rate of deforestation, the world’s rainforests could diminish and virtually vanish within the next 100 years at our current rate of depletion. This not only causes loss of habitat for millions of species, but a steep negative impact on climate change as well.
Why is our little green planet growing less green?
Our little green planet is growing less green by the minute, not due to any natural biological terror, but our own devices . And it’s no mystery what habits of ours are leading global deforestation, nor how such acts will affect the well-being of Earth.
