III. Greenhouse Gas Emissions in Agriculture

A. Sources of Emissions

Crop Production: Agriculture's emissions from crop production are multifaceted and include:
- CO2 Emissions: Carbon dioxide emissions primarily arise from soil cultivation practices such as plowing, tilling, and soil erosion. These activities disrupt soil organic matter, releasing stored carbon into the atmosphere. In 2050, global CO2 emissions from agricultural soils are estimated at 3.3 billion metric tons annually.
- Nitrous Oxide (N2O) Emissions: Nitrous oxide is a potent GHG emitted from agricultural soils, particularly during fertilizer application. The use of nitrogen-based fertilizers contributes significantly to N2O emissions, which have a warming potential far greater than CO2. Annual global emissions from fertilizer use in agriculture are projected to reach 1.2 million metric tons of CO2-eq by 2050.
- Methane (CH4) Emissions: Methane emissions in agriculture primarily originate from flooded rice paddies and anaerobic conditions in wetland soils. In 2050, global methane emissions from rice cultivation are estimated at 600 million metric tons annually.
Livestock: Livestock production is a major source of agricultural emissions, contributing primarily through:
- Enteric Fermentation: Ruminant animals, such as cattle, sheep, and goats, produce methane during digestion. Enteric fermentation is the largest source of methane emissions from livestock, accounting for approximately 2.5 billion metric tons of CO2-eq annually by 2050.
- Manure Management: Improper handling and storage of animal manure lead to emissions of methane and nitrous oxide. Globally, emissions from manure management are projected to reach 900,000 metric tons of CO2-eq annually by 2050.
Land-Use Changes: Agricultural expansion and land-use changes, including deforestation and conversion of natural habitats to cropland, release stored carbon into the atmosphere:
- Deforestation: Deforestation for agricultural purposes releases significant amounts of carbon dioxide stored in trees and soil organic matter. In 2050, annual global emissions from deforestation in agriculture are estimated at 4.0 billion metric tons of CO2-eq.
- Soil Carbon Loss: The conversion of natural ecosystems, such as forests and grasslands, to agricultural land leads to soil carbon loss. This process contributes an additional 1.0 billion metric tons of CO2-eq annually to global emissions.

B. Emission Trends
