Showing results for: Carbon sinks and sequestration
A report from the National Academies of Sciences, Engineering, and Medicine summarises a webinar and workshop that addressed the current state of knowledge on managing land to remove carbon dioxide from the atmosphere, the research needed for predicting the relevant impacts of land use change and management practices and the state of knowledge on policies, incentives, and socio-economic constraints on terrestrial carbon sequestration activities.
A new paper finds that a range of “ambitious but not unrealistic” climate mitigation options could, together, mean that using bioenergy with carbon capture and storage (BECCS) is not necessary for staying within 1.5°C of warming. Mitigation options considered include limiting population, lower meat consumption and use of lab-grown meat, lifestyle changes such as lower car use, electrification of energy end-use sectors, high efficiency manufacturing, agricultural intensification and mitigation of non-CO2 greenhouse gases.
This article evaluates the “4 per 1000” initiative’s potential to increase soil organic carbon (SOC) by assessing 16 long-term soil experiments conducted by the UK based Rothamsted Research, involving 114 different soil treatments (including addition of farmyard manure (FYM), nitrogen fertilisers, pasture leys, conversion of arable land into woodland and residue incorporation) over 7–157 years.
In this paper, researchers from the Joint Research Centre of the European Commission investigate the extent to which variation in nitrous oxide (N2O) emissions may offset or enhance the mitigation effects of carbon sequestration in arable European soils. They employ a biogeochemical model with input data from ~8000 soil sampling locations to quantify CO2 and N2O flux associated with different agricultural practices aimed at carbon (C) mitigation.
This report by the Meridian Institute brings together existing information about climate change impacts and opportunities for climate adaptation and mitigation into a food systems framework.
This study, undertaken by researchers at Michigan State University and the Union of Concerned Scientists, compares the net greenhouse gas (GHG) balance of two different beef finishing systems in the Upper Midwest, of the United States: a feedlot system; and a grazing system based on adaptive multi-paddock (AMP) grazing principles.
The FAO has just published a briefing paper which proposes three ways to substantially reduce emissions from livestock production.
Using volcanic rock dust as a fertiliser on farms could offset around one tenth of global greenhouse gas emissions, according to preliminary estimates.
Scotland’s soils contain over half of the UK’s soil carbon stock, making it important to know how to avoid soil carbon loss. The Scottish landscape is currently a net sink for carbon (mainly due to forestry). A recent report assesses current knowledge on soil carbon and land use in Scotland.
A report by the European Academies’ Science Advisory Council finds that negative emissions technologies (NETs) have ‘limited realistic potential’ and cannot be relied upon to remove carbon at the rate envisaged in the Intergovernmental Panel on Climate Change (IPCC) scenarios for avoiding dangerous climate change.
This paper, by researchers from the US and the Netherlands, presents the findings of a model analysis that estimates how much soil organic carbon (SOC) has been lost, and from where, as a result of land use and land cover change (LU-LCC) associated with human agricultural activities.
Breakthrough Strategies & Solutions has released a report based on their conference ‘Sequestering Carbon in Soil: Addressing the Climate Threat’ held in May 2017.
In this opinion piece, Edward Parson of the Emmett Institute on Climate Change and the Environment, UCLA, argues that Climate Engineering (CE) must urgently be given greater and more serious consideration within climate change research and policy, and calls upon the IPCC to take responsibility for this.
This paper discusses EU climate and agriculture policy instruments and analyses how these can motivate farmers to adopt soil carbon sequestration projects.
This paper takes countries’ mitigation targets (Intended National Determined Contributions, or INDCs), submitted since the Paris Climate agreement, and, using supplementary information from other official documents, quantifies how much of the promised actions are related to Land Use, Land Use Change and Forestry (LULUCF, primarily deforestation and forest management).
This paper by researchers in Germany explores the scalability of managed woody and herbaceous bioenergy plantations (BP) for terrestrial capture of atmospheric carbon. The researchers make simulations to quantitatively explore how much land area could be made available globally for this terrestrial carbon dioxide removal (tCDR) strategy.
