Greenhouse gas (GHG) emissions in agricultural systems can be categorized as direct and indirect emissions. Direct emissions include methane from enteric fermentation in livestock, manure management, and rice cultivation, as well as nitrous oxide from agricultural soil management. Indirect emissions result from energy-intensive activities such as machinery operation, irrigation, and processing, releasing carbon dioxide. Additionally, the application of synthetic fertilizers and pesticides contributes to nitrous oxide emissions and energy-intensive processes, respectively. Land use changes, especially forest conversion to agricultural land, release stored carbon dioxide. These emissions highlight the diverse sources within agricultural systems, emphasizing the need for sustainable practices to mitigate their impact on climate change.
