    Grasslands cover about 70% of the world’s agricultural area. They have a crucial role in terms of food production and in the delivery of ecosystem services such as water supplies, biodiversity and carbon sequestration. The grasslands of the world face a range of challenges from climate change including the effects of elevated atmospheric carbon dioxide, increasing temperatures, changes in precipitation regime and higher concentrations of ground level ozone. These factors threaten pro ductivity, species composition and quality, with potential impacts not only on livestock production but also on other aspects of the multifunctional role of grasslands. In a previous work we considered the contribution grasslands make to greenhouse gas emissions and the potential of genetic improvement of key grassland species to reduce these emissions and enhance carbon sequestration in grassland soils. In this paper we summarize the targets and approaches plant breeding programmes sh ould adopt to enable grasslands to adapt to climate change whilst realizing their potential contributions to food security and reducing the environmental impact of livestock agriculture.

    Mitigation of greenhouse gas emissions in livestock production – A review of technical options for non-CO2 emissions 2013
    Also available in:

    Animal agriculture substantially contributes to the world economy by providing food, jobs, and financial security for billions of people. With increasing concerns over global climate change and pollution, efforts are underway to reduce the overall environmental impact of animal production. This document analyses emission of non-carbon dioxide greenhouse gases, an important segment of the environmental footprint of animal production. It has been developed by a team that included experts in animal /ruminant nutrition, manure and soil management, animal and whole-farm modeling, and animal reproduction. Over 900 publications focusing on nutritional and manure management mitigation strategies for methane (enteric or from manure) and nitrous oxide emissions were reviewed and analysed, and a synthesis of feed-, animal management- and manure management-based mitigation approaches and interactions amongst them has been presented. This document will help researchers, animal industry consultants, policy-makers, animal producers, non-governmental organizations, and other groups with interest in maintaining a viable and environmentally-responsible animal production sector to make sound decisions on selection and adoption of effective and economically feasible greenhouse gas mitigation practices.

    Greenhouse gas inventory over Malaysia forest land
    XV World Forestry Congress, 2-6 May 2022

    Greenhouse gases such as carbon dioxide, methane and nitrous oxide exist naturally in the atmosphere. Their presence contributes to the greenhouse effect that makes life possible on planet Earth. However, the human activities have increased the accumulation of GHGs in the atmosphere contributing to adverse climatic changes. This poster provides an overview of greenhouse gas from forest over Malaysia, methodology for estimating emissions & removals for forest land and potential reduction through mitigation actions. As pledged in our Nationally Determined Contribution (NDC), Malaysia intends to maintain forest cover at least 50 percent and to reduce the greenhouse intensity of GDP by 45% by 2030 relative to the emission intensity of GDP in 2005. Keywords: Climate change, Sustainable forest management, Research ID: 3476920
