Study Notes
Greenhouse Gas Emissions in Agriculture
- The agriculture, forestry, and land use sector contributes around 24% of global greenhouse gas emissions.
Greenhouse Gases in Agriculture
- Carbon dioxide (CO2) and nitrous oxide (N2O) make up over half of total greenhouse gas emissions from agriculture.
Causes of Increased Greenhouse Gases
- Deforestation and land-use changes are one of the main causes of the increase in greenhouse gases observed over the past 250 years.
- Burning of fossil fuels for energy is another major cause of the increase in greenhouse gases.
- Agriculture, especially livestock production, is the third main cause of the increase in greenhouse gases.
Greenhouse Gas Emissions from Farm Animals
- Ruminant farm animals, such as cattle, sheep, and goats, have a digestive system that ranks high in greenhouse-gas emissions due to methane production.
Efficient Farm Animals
- Monogastric animals, such as pigs and chickens, have a higher feed-conversion efficiency and produce less methane compared to ruminant animals.
