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 does pest and disease affect agriculture?

- Damage to Finished Products. Pest species can also cause much harm to finished products that are getting ready for sale. …
- Equipment and Machinery Damage. Rodents are the biggest problem. …

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 …
How does agriculture cause deforestation in the rainforest?
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.
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.
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.
Does animal agriculture cause deforestation?
The livestock sector is also one of the leading drivers of global deforestation, and is linked to 75 percent of historic deforestation in the Brazilian Amazon rainforest. Nearly a third of biodiversity loss to date has been linked to animal agriculture.
How does agriculture affect 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. 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.
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 does farming deforestation affect the environment?
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 does agriculture contribute to climate change?
Agriculture contributes to climate change At every stage, food provisioning releases greenhouse gases into the atmosphere. Farming in particular releases significant amounts of methane and nitrous oxide, two powerful greenhouse gases.
How does animal agriculture affect the environment?
Animal agriculture produces 65% of the world’s nitrous oxide emissions which has a global warming impact 296 times greater than carbon dioxide. Raising livestock for human consumption generates nearly 15% of total global greenhouse gas emissions, which is greater than all the transportation emissions combined.
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.
Trees and other plants take in carbon dioxide during photosynthesis, making them key actors for ecosystem health and climate regulation. Yet human changes to landscapes, especially deforestation, have released carbon back into the atmosphere for centuries.
The leading cause of global deforestation is agriculture.
