Organic farming to combat climate change

Organic farming can help combat climate change in several ways: 1) It sequesters carbon through biological processes like plant growth and soil accumulation of organic matter. 2) It reduces greenhouse gas emissions from agriculture by using less energy-intensive practices and eliminating synthetic fertilizers and pesticides. 3) Switching to organic farming in European countries is expected to reduce agricultural greenhouse gas emissions by 2.1-2.4% by 2030, helping combat climate change.
Organic farming to combat climate change
- 1. Organic Farming: To combat climate change Presented By: D. Sarath Kumar; Student of M. Sc. Agri. (Agronomy) 1st SEM, Roll. No: 180805190006
- 2. Introduction Agriculture in developing countries like India must undergo a significant transformation in order to meet the related challenges of achieving food security and responding to climate change. Some estimates also indicate that climate change is likely to reduce agricultural productivity, production stability and incomes in some areas that already have high levels of food insecurity. In this scenario organic farming is thus crucial to achieving future food security and climate change goals.

- 5. Climate Change Climate change refers to the variation in the Earth’s global climate or in regional climate over time. It could show up as a change in climate normal’s for a given place and time of year, from one decade to next. Between 1800-2015 earth’s average global temperature is increased by 0.9°C (1.5°F) (NASA, August 2106)
- 7. Global Warming Global Warming is an increase in average temperature of the Earth’s atmosphere, especially a sustained increase great enough to cause changes in the global climate. Green Houses Gases are the major responsible for the Global Warming. Man made activities accounts more of releasing the harmful gases than the natural way of releasing the green houses gases.
- 8. Green House Gases Emission of green house gases like Carbon dioxide, Methane, Nitrous Oxide, etc., into the atmosphere. The major source is Carbon dioxide (80%). Remaining 20% by Methane and Nitrous oxide. GHG emission were 60% high in 2014 than 1990. (World bank,2014) Acc. to IPCC, 2014 the primary source of GHG is burning of fossil fuels.
- 9. Since 1880 CO2 concentration increased from 290 ppm to 430ppm. By 2030 it may increase up to 450 ppm and 1300 ppm. (IPCC, 2014) GHG from different source: (NASA,2016) - 5.65 kg CO2 eq / kg from rice field. - 45.54 kg CO2 eq / kg from Mutton meat - 2.4 kg CO2 eq / kg from Milk. Methane emission from Agricultural and livestock accounts for 14.5% global CO2 eq emissions. (FAO,2014) Emission of Methane from the rice field can be reduced by the proper Water management in the Paddy field. (Nayak et.al, 2015)
- 10. Enteric fermentation Enteric fermentation is a natural part of the digestive process in ruminant animals such as cattle, sheep, goats, and buffalo. Microbes in the digestive tract, or rumen, decompose and ferment food, producing methane as a by-product.
- 16. Ways to combat climate change 1) Sequesters Carbon 2) Less polluted water 3) Reduce chemical load 4) Uses less energy 5) Stops digging the ditches. By following Organic farming in European countries the GHG from agricultural sources expected to reduced by 2.1% by 2020 and 2.4% by 2030. (European commission, 2015)
- 17. Biological Sequestration • It is typically accomplished through conservation practices that enhance the storage of carbon (such as restoring forests, wetlands, and grasslands) or reduce CO2 emissions (such as reducing agricultural tillage and suppressing wildfires). • Soil carbon sequestration is the process of removing CO2 from the atmosphere by plants accumulating organic matter in soil.
- 18. Carbon Capture and Sequestration (CCS) • It is any industrial process that diverts CO2 from emission to the atmosphere and sequesters those emissions. • The CO2 is then injected deep into rock formations where it could potentially remain for millennia.
