Is loss of forests a major contributor to greenhouse gas emissions and percent of greenhouse gas emissions is forestry and agriculture responsible?
Yes, Land use change is a major contributor is GHG globally, whereas forest fires are contributing to 60-70 million tonnes of CO2 emissions.
Yes, deforestation refers to the purposeful clearing or thinning of trees and forests. When deforestation occurs, much of the carbon stored by trees is released back into the atmosphere as carbon dioxide, which contributes to climate change . Since forests absorb carbon dioxide, destroying them also limits nature's ability to keep emissions out of the atmosphere. Deforestation, together with agriculture and other land use changes, is responsible for roughly a quarter of global greenhouse gas emissions. Trees have an exceptional ability to trap and accumulate greenhouse gases, saving the planet from overheating. However, large-scale and uncontrolled deforestation increases greenhouse gases and adds substantially to the rise in temperature and the escalation of climate change. The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sector contribute between 13% and 21% of global greenhouse gas emissions. Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. These greenhouse gas emissions contribute to rising temperatures, changes in patterns of weather and water, and an increased frequency of extreme weather events. As per the national GHG inventory, the agriculture sector emits 408 MMT (million metric ton) of CO2 equivalent. Rice cultivation is the third highest source (17.5%) of GHG emissions in Indian agriculture after enteric fermentation (54.6%) and fertilizer use (19%). When forests are cleared or burnt, stored carbon is released into the atmosphere, mainly as carbon dioxide. Averaged over 2015—2017, global loss of tropical forests contributed about 4. 8 billion tonnes of carbon dioxide per year.
Yes, loss of forests is a major contributor to greenhouse gas emissions. According to the Intergovernmental Panel on Climate Change (IPCC), deforestation and forest degradation account for up to 11% of global greenhouse gas emissions each year. This is nearly as much as all of the world's transportation emissions combined.
When forests are cleared, the carbon that they have stored in their biomass and soil is released into the atmosphere as carbon dioxide, a greenhouse gas. This contributes to global warming and climate change.
Forestry and agriculture are responsible for a significant portion of greenhouse gas emissions. According to the World Resources Institute, the combined emissions from agriculture, forestry, and other land use (AFOLU) accounted for 24% of global greenhouse gas emissions in 2020. Of this, deforestation and forest degradation accounted for 11%, while agriculture accounted for 13%.
It is important to note that forests also play an important role in absorbing carbon dioxide from the atmosphere. However, the rate of deforestation is outpacing the rate of reforestation, meaning that there is a net loss of forest cover each year. This is contributing to the rise in greenhouse gas emissions and climate change.
There are a number of things that can be done to reduce greenhouse gas emissions from forestry and agriculture. These include:
- Reducing deforestation and forest degradation
- Restoring forests
- Planting new trees
- Improving agricultural practices to reduce emissions
By taking these steps, we can help to protect our forests and mitigate the impacts of climate change.
Land use change, principally deforestation, contributes 12–20% of global greenhouse gas emissions. Forest degradation (changes that negatively affect a forest's structure or function but that do not decrease its area), and the destruction of tropical peat lands, also contribute to these emissions.Clearing and burning tropical forests accounts for about 20% of global annual Greenhouse Gas emissions, about as much as all of the fossil fuels burned in the US every year and more than the world's transportation sector. Earth's greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor. In addition to these natural compounds, synthetic fluorinated gases also function as greenhouse gases.The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sector contribute between 13% and 21% of global greenhouse gas emissions. As per the national GHG inventory, the agriculture sector emits 408 MMT (million metric tons) of CO2 equivalent. Rice cultivation is the third highest source (17.5%) of GHG emissions in Indian agriculture after enteric fermentation (54.6%) and fertilizer use (19%). Agriculture is both a victim of and a contributor to climate change. On the one hand, agricultural activities contribute approximately 30 per cent of total greenhouse gas emissions, mainly due to the use of chemical fertilizers, pesticides and animal wastes. In India, 68.7% percent of GHG emissions come from the energy sector, followed by agriculture, industrial processes, land-use change and forestry, and waste which contribute 19.6 percent, 6.0 percent, 3.8 and 1.9 percent relatively to GHG emissions. The sheer volume of CO₂ emitted by coal-fired power plants makes the electric power sector the largest source of GHGs in India. The second-largest contributor is the agriculture sector, which produces huge amounts of methane (CH₄) from rice paddies and cattle. Water vapor accounts for the largest percentage of the greenhouse effect, between 36% and 66% for clear sky conditions and between 66% and 85% when including clouds.

The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sector contribute between 13% and 21% of global greenhouse gas emissions.Agriculture produces a substantial amount of greenhouse gas emissions, which contribute greatly to global warming and climate change. In India, 68.7% percent of GHG emissions come from the energy sector, followed by agriculture, industrial processes, land-use change and forestry, and waste which contribute 19.6 percent, 6.0 percent, 3.8 and 1.9 percent relatively to GHG emissions. More than 95 percent of India's power sector emissions are produced by coal-fired power plants - the country's primary source of electricity generation. The second-largest contributor to greenhouse gas emissions in India is the country's important agriculture sector. Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun's heat. Land use change, principally deforestation, contributes 12–20% of global greenhouse gas emissions. Clearing and burning tropical forests accounts for about 20% of global annual Greenhouse Gas emissions, about as much as all of the fossil fuels burned in the US every year and more than the world's transportation sector. Yes, loss of forests is a major contributor to greenhouse gas emissions. Plants take up carbon dioxide exhaled by animals and release oxygen inhaled by animals. Thus, forests maintain a balance between the two gases in atmosphere. Deforestation disturbs this balance and increases the amount of carbon dioxide in atmosphere.
