Enteric fermentation

Enteric fermentation is a digestive process by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream of an animal.

  • Fertiliser, manure and straw management (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    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 management

    Type: 
    Technology
    Sectors:
    Objective:

    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 Mechanism

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    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.

  • Feasibility Assessment: Short-Lived Climate Pollutants Finance Innovation Facility

    Type: 
    Publication
    Publication date:
    Objective:

    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.

  • Chemical fertiliser amendment (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    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.

  • Electron acceptors (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    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.

  • Alternate wetting and drying (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    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.

  • Agricultural biotechnology (rice)

    Type: 
    Technology
    Sectors:
    Objective:

    The biotechnology approach for methane mitigation technology involves identification of rice cultivars which emit less methane. It also involves the tailoring of plants which translocate less photosynthate to the roots and more to reproductive parts. 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.
