ROLE OF AGRICULTURE IN GREEN HOUSE GAS EMISSIONS

by Meena Pandey | 16-09-2019 21:21 recommendations 0

Agriculture is responsible for 7% of total emissions of greenhouse gases into the atmosphere . . Although agriculture is not the major source of greenhouse gas emissions, its role in agriculture is vital . The use of fossil fuels in agricultural production accounts for eight percent of total greenhouse gases emissions.Using renewable fuels can reduce the carbon dioxide emission from agriculture.

Agriculture soil management is one of the factor that brings about greenhouse gases emission. Nitrous oxide is produced naturally in soils through the microbial processes of nitrification and de-nitrification. During nitrification, ammonium (NH4) produces nitrates (NO3,). During de-nitrification, nitrates (NO3,) are reduced to nitrogen gas (N2). An intermediate step in both of these processes is the creation of nitrous oxide (N20).Similarly,enteric fermentation of cattle produces 40% of total agricultural green house gas emission. Methane is produced by the anaerobic (without oxygen) decomposition of manure. When manure is handled as a solid or deposited naturally on grassland, it decomposes aerobically (with oxygen) and creates little methane emissions. However, manure stored as a liquid or slurry in lagoons, ponds, tanks or pits, decomposes anaerobically and creates methane emissions. Dairy cattle and swine produce about 85 percent of the methane emissions. Methane emissions will increase as the number of large scale livestock confinement systems increases. The use of fossil fuels in agriculture production also plays significant role in emission of greenhouse gases.10% of the greenhouse gas of agricultural sector is produced by paddy rice. Methane in rice paddies is produced by microscopic organisms that respire CO2, like humans respire oxygen. More CO2 in the atmosphere makes rice plants grow faster, and the extra plant growth supplies soil microorganisms with extra energy, pumping up their metabolism. Synthetic fertilizers also contribute 13% of emission of greenhouse gases.16%of agricultural greenhouse gas is due to manure left on pasture land and 7% is emitted due to its management. Burning of savannahs contribute to 5% of agricultural greenhouse gas emission.

 

Agriculture is arguably the most essential sector of the global economy, but there is something you can do to reduce its greenhouse gas emissions at the individual level. As mentioned above, cutting your intake of red meat is a good place to start. Eating more vegetables is a good next step.
Eating vegetables produces lower greenhouse gas emissions¡¦ For example, potatoes, rice, and broccoli produce approximately 3–5 times lower emissions than an equivalent mass of poultry. The reason is simple – it¡¯s more efficient to grow a crop and eat it than to grow a crop, feed it to an animal as it builds up muscle mass, then eat the animal.

    Wow, Meena pandey,
    Thanks for this informative report. Of course Agriculture as described by you is one of the major activities that helps in the increasement of the Global Green House gases. Since our main profession and the economy of country is dependent on agriculture so we can't totally avoid and stop it as it produce GHGs but we can seek for the alternatives for its reduction. Small things can bring a huge change.
    Green Cheers,
    Yours
    Sandhya
