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.

    Technology:

    Stanford researchers have developed a method for converting ammonia in wastewater into nitrogen gas while simultaneously generating power in a bioreactor system. This method produces energy from carbon and nitrogen waste and provides significant cost and energy savings over current options.

    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.

    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.

    Failing to limit our emissions of carbon dioxide will have severe consequences for the world’s oceans. This report contends that the marine environment is doubly affected: continuing warming and ongoing acidification both pose threats. Accordingly, proactive and resolute action is needed in order to ensure that the oceans do not overstep critical system limits.

    This, the summary report of a Royal Society discussion meeting on food crops in a changing climate, outlines new research that demonstrates that the impact of climate change on crop yields and quality will be more severe than previously thought. It highlights the need for research to improve the resolution and complexity of climate models and the consequent requirement for enhanced computer power.

    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.

    To provide quantitative information for the debate on the burden sharing of the European Union target to reduce greenhouse gas (GHG) emissions in 2020 by 20 per cent, this report assesses the potential and costs for further mitigation of the non-carbon-dioxide (CO2) GHG emissions beyond the currently agreed policies. It addresses the non-CO2 gases included in the Kyoto protocol [i.e., methane (CH4); nitrous oxide (N2O); and the three F-gases: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

    Objective:

    Within the topical issue of climate change, this paper zeroes in on the problem of high methane emissions. It reviews the current situation with regards to methane emissions, and then continues to discuss the economic aspects, such as the Carbon Market, before concluding with some key action points. It is argued that climate change policy targets are set in terms of greenhouse gas emission reductions.
