Outline:
Because of its effective absorption of infra-red radiation, methane gas (CH4) plays a direct role as a green house gas in our global climate. Methane accounts for about 15% to the current commitment to global warming. Its global warming potential is 11 times larger than CO2. Methane emission from paddy soil is influenced by factors such as soil properties (potential reduction oxidation, organic matter, nutrient status, mineralogy, pH, texture, soil temperature), climate (rainfall, temperature), plant varieties, and practical planting (planting, fertilizing, irrigation, fallow, weed, harvest).
This lecture will give a review on CH4 emission from paddy fields, giving special attention to mitigation optionts from the view-point of their feasibility on a field scale. Field management of paddy fields is primarily not only to obtain suitable rice yield, but it also has physical, chemical, and biological effects on CH4 emission. Amongst various field managements, some management practice can be win-win options that sustain rice yield and mitigate CH4 emission. Water management is effective practise in rice yield sustainable and also decreasing CH4 emission. Other practise, such as mature organic matter application, can also has positive effects on increasing rice yield and decreasing CH4 emission. The use of Azolla in the dual cropping system can also decrease CH4 emission, although sometimes can not effect to increase rice yield.
