• The Indo- Gangetic Plain (IGP) is the global hot-spot of atmospheric ammonia (NH3) due to intense agricultural activities and fertilizer production there, according to researchers at The Indian Institute of Technology (IIT) Kharagpur.
• IGP is the global hot-spot of NH3 due to intense agricultural activities and fertilizer production.
• There is a positive correlation of NH3 with total fertilizer consumption and temperature since high temperature favours volatilization.
• Agricultural emission is negatively correlated with total precipitation as wet deposition helps removal of NH3.
• NH3 plays a key role in the deterioration of air quality by actively contributing to the formation of secondary aerosols.
Agricultural emissions in India:
• Agriculture sector is responsible for climate change due to Greenhouse gas (GHG) emissions.
• They are generated through the production and use of agricultural inputs (mainly water, fertilisers, and pesticides) farm machinery, soil disturbance, residue management and irrigation.
• Agriculture and livestock account for 18% of gross national emissions of C02 in India.
Steps to decrease emissions:
• Low External Input Sustainable Agriculture (LEISA), which seek to optimise the use of locally available resources replacing external inputs.
• Zero Budget Natural Farming (ZBNF), a low-input, climate-resilient type of farming that eliminates the use of chemical fertilisers and pesticides.
