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.

  • Summary for policymakers. Climate change 2007: the physical science basis

    Type: 
    Publication
    Publication date:
    Objective:
    Approach:

    The Working Group I contribution to the IPCC Fourth Assessment Report describes progress in  understanding of the human and natural drivers of climate change, observed climate change, climate processes and attribution, and estimates of projected future climate change. It builds upon past IPCC assessments and incorporates new findings from the past six years of research.Key findings include:

  • Could agriculture help to prevent further climate change?

    Publication
    Publication date:
    Objective:
    Approach:

    There is growing evidence that greenhouse gas emissions from human activity contribute to climate change. Many people blame modern farming practices for accelerating this - agriculture produces between 16.8 and 32.2 percent of global greenhouse gas emissions. But could agriculture also hold some solutions to climate change?Research for Geenpeace
    International by the University of Aberdeen, in the UK, analyses the
    contribution of modern farming to human-induced climate change. The main

  • Can voluntary carbon offsets pay for development?

    Type: 
    Publication

    Objective:
    Approach:

    Since the Kyoto Protocol was signed in 1997, several ‘carbon markets’ have emerged. These enable governments to trade carbon credits and meet Kyoto targets. A voluntary market has also appeared, in which organisations and individuals can offset their greenhouse gas emissions by preventing a similar amount of gases being released elsewhere.Research from the
    International Institute for Environment and Development, UK, examines whether
    voluntary carbon markets can provide a new source of funding for sustainable
    development.

  • 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.

  • Emission Scenarios for Non-CO2 Greenhouse Gases in the EU-27--Mitigation Potentials and Costs in 2020

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    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).

  • The future oceans: warming up, rising high, turning sour

    Type: 
    Publication
    Publication date:
    Objective:

    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.

  • Food crops in a changing climate: report of a Royal Society discussion meeting

    Type: 
    Publication
    Publication date:
    Objective:

    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.

  • Reducing methane emissions: the other climate change challenge

    Type: 
    Publication
    Publication date:
    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.
