Cattle ranching, animal agriculture, and logging are the leading causes of deforestation in our forests. The forest is cut to provide timber to build houses and create specialty wood products, or burned to make room for cattle grazing and feed crop production.Sep 20, 2019


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;

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 …


What is the main cause of deforestation?

Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation.

Why is agriculture a threat to the rainforest?

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.

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 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 does agriculture impact 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 deforestation in agriculture?

Deforestation is the conversion of forest to other land uses, such as agriculture and infrastructure. Worldwide, more than half of forest loss is due to conversion of forest into cropland, whereas livestock grazing is responsible for almost 40 percent of forest loss, according to the new study.

What agriculture methods cause desertification?

Desertification occurs when the anthropogenically induced degradation exceeds the ecosystem’s restorative capacity. The major causes of desertification include overgrazing, overcultivation of marginal land, unsustainable ‘slash-and-burn’ agricultural practice, logging for fuelwood, and poor irrigation techniques.

How much forest is cut down for agriculture?

Every year the world loses around 5 million hectares of forest. 95% of this occurs in the tropics. At least three-quarters of this is driven by agriculture – clearing forests to grow crops, raise livestock and produce products such as paper.

How do agricultural wastes harm the environment?

In many parts in developing countries, agricultural solid wastes are indiscriminately dumped or burnt in public places, thereby resulting in the generation of air pollution, soil contamination, a harmful gas, smoke and dust and the residue may be channeled into a water source thereby polluting the water and aquatic …

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 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.

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.

Why is agriculture deforested?

Agricultural deforestation happens because of increased global demand for such commodities, government policies to stimulate that demand, and trade and finance policies that facilitate their expansion and sale. Other causes include illegal logging, mining and poor forest management.

What is the main cause of deforestation?

Agriculture is the main cause of deforestation. Eighty per cent of global forest loss is due to converting forests to farmland to produce agricultural commodities, such as beef , soy , palm oil and rubber which are largely exported.

What are the major imports of deforestation?

They show that the EU is one of the major importers of ‘forest risk commodities’: such as palm oil (17% of global imports), soy (15%), rubber (25%), beef (41%), maize (30%), cocoa (80%), and coffee (60%).

How much forest has been deforested in the world?

Forests, including rainforests like the Amazon, continue to be deforested at an alarming rate: between 1990 and 2016, the world lost a staggering 1.3 million square kilometres of forest.

Does the EU have a law against deforestation?

The EU is developing a law to tackle deforestation. It aims to guarantee that products sold in the EU don’t destroy the planet’s forests. But if the EU wants to have a real impact on the fight against deforestation, it must do more than clean up its own supply chains.

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.

Why does deforestation happen?

It can also happen gradually as a result of ongoing forest degradation as temperatures rise due to climate change caused by human activity.

How does infrastructure affect deforestation?

Some infrastructure activities, such as road building, have a large indirect effect through opening up forests to settlers and agriculture. Poor forest management and unsustainable fuelwood collection degrade forests and often instigate a “death by a thousand cuts” form of deforestation.

What are the consequences of forest fires?

The resulting loss has wide-reaching consequences on biodiversity, climate, and the economy.

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.

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.
