Agriculture for climate change mitigation and
adaptation

1. Greenhouse gas mitigation mechanism in agriculture
1. Reduction in emission of GHGa) Efficient management flow of C & N in agro-ecosystemsb) Management of livestock and their feedc) Nutrient and water management in rice
2. Enhancing removal of atmospheric GHGa) By C sequestration – 90% mitigation by sink enlargementb) By increasing photosynthetic input of C in agro-ecosystemc) By oxidation of methane from agricultural lands.
3. Avoiding emission
a) Converting greenhouse gas to fuels such as phenol and bio fuels.

Apply compost as much as possible
C- sequestration Increase soil organic carbon in agriculture system (apply
organic matter): improves c sequestration potential; lowerCH4 and N2O emission; conserve farming energy; storemore water, increases soil quality and fertility, better soilstructure and water availability

CH4 and N2O mitigation Intermittent irrigation/mid-season drainage/non-flooded
soil condition reduces methane 70-90%. Use of compost + aerobic soil condition reduces methane
emission Aerobic rice rhizosphere can oxidize methane 19-90%Avoiding continuous soil saturation reduces methane
emissions from rice fields without generating offsetting nitrous oxide emissions.
SRI principles: intermittent irrigation/ non-flooded soil condition, single seedlings transplant, transplanting
with wider spacing and use of compost

2. Climate change adaptation and SRIThe challenge of climate change adaptation is to
(i) Produce more food, (ii) more efficiently, (iii) under more volatile production conditions
Those practices that confer tolerance to drought –SRI
Early maturation in order to shorten the growing season and reduce farmers’ exposure to risk of extreme weather events – SRI
Tolerance to pest and diseases – SRI
Less economic loss

• Vulnerability, resilience and disaster preparedness
• Low carbon societies and renewable energy
• Water resources and coastal adaptation strategies
• Urban and rural sustainability
• Agriculture, forestry and land use
• Cleaner production and climate change
