By overlaying recent maps of commodity production areas with maps of historical tree cover loss
What is the difference between deforestation and logging?
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.
What is deforestation agriculture?
Deforestation is the large-scale clearing of land, generally for agriculture, industry, or transportation. Upwards of 50,000 acres of forest are cleared by farmers and loggers per day worldwide.
How deforestation affects the productivity of the agricultural sector?
When tropical forests are cleared, the physical and chemical properties of the soil undergo significant changes leading to nutrient loss, accelerated soil erosion, and declining yields.
How does trees affect agriculture?
Forest and trees sustain agriculture through the provision of ecosystem services that support crop production. These services include nutrient cycling, pollination, seed dispersal, soil formation, natural pest and disease control and climate and water regulation.
How does forestry help agriculture?
It can also protect crops, improve water quality, improve nutrient utilization, and enhance carbon sequestration. FOREST FARMING grows and protects high-value specialty crops under the forest canopy, which is adjusted to the correct shade level the crops prefer.
How do trees help agriculture?
Agriculture that includes trees boosts food production, stores carbon and saves species. Pine trees line a vineyard in Restinclières, France. Integrating trees with crops helps soil retain moisture and store carbon, plus farmers have extra sources of income.
What are the two consequences 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.
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 help farmers?
Shade trees can increase the water and nutrient holding-potential of the soil, and their fallen leaves create organic matter in the soil. When fruit or timber trees are used, these can provide additional income to farmers that can complement the income from the cash crop.
What are the benefits of a forest?
With clear rights, communities are better able to manage standing forests as economic assets and realize multiple benefits from activities such as sustainable logging, sale of non-timber forest products (like honey, spices, and nuts), and payment for ecosystem services, such as watershed protection.
What are the key commitments of global food producers, corporates and multinationals?
Global food producers, corporates and multinationals purchasing key commodities must commit to stop deforestation with fixed and accountable targets. Companies that have made no-deforestation commitments must be pressured to adhere to global standards and penalized if they do not comply.
What products do farmers need to meet the ever increasing global demand?
Meanwhile the farmers working to meet the ever-increasing global demand for products like coffee, tea, and cocoa, struggleto feed their own families.
How did the fires in the Amazon affect the world?
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.
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 much of the world’s soy is deforested?
Globally, soy farms occupy 8.2 Mha of land deforested between 2001 and 2015. 17 Almost all (97 percent) of this deforestation occurred in South America, with 61 percent in Brazil, 21 percent in Argentina, 9 percent in Bolivia, and 5 percent in Paraguay. The Brazilian state of Mato Grosso had by far the most forest replacement for soy, accounting for over one-third of the total. Within Brazil, 48 percent of forest area replaced by soy occurred in the Amazon, with an additional 45 percent in the Cerrado.
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.
Why is the three year moving average more accurate?
The three-year moving average may represent a more accurate picture of the data trends due to uncertainty in year-to-year comparisons . All figures calculated with a 3 percent minimum tree cover canopy density.
When did deforestation occur in Indonesia?
The amount of deforestation that occurred previously on land now used for oil palm plantations increased markedly between 2001 and 2012 —with peaks in 2009 and 2012–then declined to a record low in 2015 as part of a more than sixfold decline in overall deforestation rates in Indonesia and Malaysia. Studies have cited lower prices for crude palm oil (with reductions in deforestation rates generally lagging price drops by one year), Indonesia’s moratorium on new licenses to convert primary forests and peatlands (implemented in 2011), and corporate zero-deforestation commitments as possible explanations for the decline. 14
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 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.

What were the factors that contributed to the expansion of agriculture?
In the sixteenth and seventeenth centuries, the abundance of land, available labour and the mobility of peasants were three factors that were responsible for the constant expansion of agriculture.
What is the biggest driver of 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.
What is agricultural extension?
Agricultural extension (also known as agricultural advisory services) plays a crucial role in boosting agricultural productivity, increasing food security, improving rural livelihoods, and promoting agriculture as an engine of pro-poor economic growth.
How does deforestation affect the environment?
Deforestation also threatens the world’s biodiversity. Tropical forests are home to great numbers of animal and plant species.
How does slash and burn agriculture help deforestation?

Why are trees more vulnerable to fire?
This causes the remaining plants to become more vulnerable to fire as the forest shifts from being a closed, moist environment to an open, dry one.
Why do trees burn?
That is because trees take in carbon dioxide from the air for photosynthesis, and carbon is locked chemically in their wood. 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.
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.
Where is the greatest amount of deforestation occurring?
Much of Earth’s farmland was once forests. Today, the greatest amount of deforestation is occurring in tropical rainforests, aided by extensive road construction into regions that were once almost inaccessible. Building or upgrading roads into forests makes them more accessible for exploitation.
What is the impact of deforestation on the environment?
Deforestation for agricultural commodities like palm oil, soy, and cattle is wiping out biodiversity and driving this climate emergency. We are at a point in time where a complete cease in deforestation and serious restoration efforts are needed to prevent mass species extinction if we are to limit global warming under 1.5°C degree world.
