Study maps rise in non-CO2 emission from cropland based agriculture over 30 years

Updated : May 30, 2019 08:37 AM IST

The agricultural sector is the world’s largest source of non-CO2 greenhouse gas emissions such as methane and nitrous oxide, both of which contribute significantly to climate change.
Methane emission from paddy fields in India declined marginally between 1980 and 2015. However, the lopsided use of nitrogen-based fertilisers has led to an increase in nitrous oxide emission, thereby contributing to the overall rise in non-carbon dioxide emissions from cropland-based agricultural activities.
The increase in nitrous oxide emission can be clearly attributed to the link between fertiliser pricing policy and disproportionate use of nitrogen-based fertiliser, finds a study.
