Showing results for: Grazing and grassland
The University of Cambridge Conservation Research Institute have set up a blog to provide space for a conversation about the future of the British countryside.
This research measures dairy cows’ motivation to access the outdoors. The results show cows are highly motivated for outdoor access. The majority of the cows in this experiment pushed through a weighted gate at least as hard to access pasture as they did to access fresh feed.
What is the latest science on soil's ability to pull carbon pollution out of the atmosphere? Breakthrough Strategies hosted a webinar on April 24 on the Technical Potential of Soil Carbon Sequestration. It featured three of the world’s leading experts on strategies for drawing carbon pollution out of the atmosphere and storing it in soils: Keith Paustian, Jean-François Soussana, and Eric Toensmeier.
This research article provides a new quantitative analysis of data on global feed use and feed use efficiency by livestock, in order to help shed light on livestock’s role in food security.
The authors of this paper compare the impact of intensification in the beef and dairy sectors via two pathways; either intensification within a system (e.g. a mixed crop-livestock system) or through transitioning to another more productive system (from pasture to mixed crop-livestock production) and assesses the mitigation potential that could arise. It reviews the impacts of these forms of intensification on both GHG emissions, land occupation and land use change (LUC), the last of which has often been excluded in other similar analyses.
The FCRN’s Tara Garnett gave a short presentation at an event held in November by the Sustainable Food Trust. The question posed was ‘Do livestock hold the key to a healthy planet and population?’
This report by Zero Carbon Australia, outlines how research on greenhouse gas emissions from land use (agriculture and forestry) can be reduced to zero net emissions, coupled with economic opportunities and increased resilience in the face of climate change. The land use sector is the second largest source of emissions in Australia and is highly exposed to the impacts of climate change. 15% of total emissions in Australia are from the agriculture and forestry sectors, the largest component of which is land clearing for grazing.
This paper presents the results of a modelling exercise that aimed to identify low emissions pathways for a growing global livestock sector. This article uses 6 case studies, modelled in the Global Livestock Environmental Assessment Model developed by FAO, to illustrate the climate change mitigation potential of livestock achievable through changes in feeding, breeding and husbandry as well as grazing management to increase soil carbon sequestration.
An academic debate on the controversial possibility of decreasing greenhouse gas emissions via increased beef production in the Brazilian Cerrado finds a new set of commentators, who have responded to an original paper by de Oliveira Silva et al. earlier in 2016 in the same journal, Nature Climate Change.
Recent assessments have strongly suggested that meeting the widely agreed target of limiting global warming to less than 2°C will require the deployment of substantial carbon sinks in addition to measures to curb greenhouse gas (GHG) emissions. This perspective article examines the latest research and thinking on the ability of agricultural soil management to reduce GHG emissions and promote soils as carbon sinks, and the practical feasibility of implementing available soil management practices
In a 2013 TED talk entitled ‘How to fight desertification and reverse climate change’ the Zimbabwean ecologist, Allan Savory, claimed that the ‘holistic management’ grazing management method that he has developed and promoted over 40 years, could stop global desertification and reduce atmospheric carbon dioxide to preindustrial levels, within a few decades.
This review article provides a summary of the multiple environmental and societal costs and benefits of livestock production. Homing in on climate change, it reviews the range of GHG mitigation options that have been proposed both on the supply side (actions that potentially reduce emissions per unit of production, or absolute emissions, considering both changes in practice and in policy) and those on the demand side (e.g. reductions in meat consumption, waste reduction).
