Greenhouse gas emission from agriculture and their mitigation strategies

The ever-increasing global demand for food and related products, agrochemicals etc. has resulted in the emission of greenhouse gases (GHG) such as CO2, CH4 and N2O. This is because agriculture contributes to around 80% of anthropogenic N2O emissions, 40% of CH4 emissions and 1% of CO2 emissions. There is a continuous increase in GHG emissions from agriculture, which leads to a number of catastrophic consequences such as climate change, global warming, biodiversity loss etc. The increase in atmospheric concentration of GHGs also affects the plant growth and its productivity. This paper discusses the potential mitigation strategies of GHG emissions by applying various management options. Mitigation strategies include implementing better management options, selecting appropriate crop varieties, conservation agriculture, reducing food waste, preventing crop residue burning etc.
