Fertiliser and manure management in rice fields are important methane mitigation technologies. The fertiliser management mitigation option includes changes in: fertiliser types; fertiliser nutrient ratios; the rates and timing of applications; and use of nitrification inhibitors to reduce methane emissions by affecting methanogenesis in rice fields. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.
Livestock are important sources of methane. The United States Environmental Protection Agency calculated that livestock, especially ruminants such as cattle and sheep, account for approximately one-third of global anthropogenic emissions of methane (US-EPA, 2006). The methane is produced primarily through the process of enteric fermentation and released through the process of eructation (Crutzen, 1995). In addition, N2O emissions are generated by livestock through secretion of nitrogen through the urine and faeces.
Alternate Wetting and Drying in Philippine Rice Production: Feasibility Study for a Clean Development MechanismType:PublicationPublication date:
Water-saving technologies such as alternate wetting and drying (AWD) provide a way to change practices to improve the livelihoods of many rice farmers and AWD is regarded as one of the more important rice cultivation methods that can dramatically save freshwater irrigation in this century. AWD not only conserves water but also mitigates greenhouse gas emissions.

This report focuses on investigating the SLCP mitigation technologies offering the highest mitigation potential of the three major SLCPs: black carbon, hydrofluorocarbons (HFCs), and methane, and each of the sectors identified by the CCAC sector initiatives. The report assesses the barriers to expediently mobilise private financial flows towards SLCP mitigating technologies in a number of key sector and markets; analyse the financial profiles of the key technologies.

Emissions of GHGs are affected by the amounts and types of fertilisers applied, so judicious choice of fertiliser application rates and fertiliser types can reduce emissions. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.
Addition of electron acceptors, such as ferrihydrite, to paddy fields can stimulate microbial populations that compete with and slow the activity of methanogens, thereby reducing emissions of methane. Rice cultivation is responsible for 10% of GHG emissions from agriculture. In developing countries, the share of rice in GHG emissions from agriculture is even higher, e.g., it was 16% in 1994.
The International Rice Research Institute (IRRI) in the Philippines has developed a new mitigation technology for methane known as alternate wetting and drying (AWD) (IRRI, 2009). AWD is a watersaving and methane mitigation technology that lowland (paddy) rice farmers can use to reduce their water consumption in irrigated fields. Rice fields using this technology are alternately flooded and dried. The number of days of drying the soil in AWD can vary according to the type of soil and the cultivar from 1 day to more than 10 days.
