Showing results for: Carbon sinks and sequestration
This report from UK charity Rewilding Britain argues that rewilding peatlands, heathland, native woodlands, saltmarshes, wetlands and coastal waters in the UK could sequester carbon and also produce other benefits such as flood mitigation, enhanced biodiversity and water quality improvement.
The UK Parliament has endorsed a motion to declare a climate and environment emergency, in response to the 2019 Extinction Rebellion protests and calls from the Labour opposition. The motion, which is not legally binding, follows declarations of a climate emergency by the Welsh Government, Nicola Sturgeon, First Minister of Scotland, and several cities across the UK.
This report from the UK think tank Green Alliance sets out how the UK could bring its land use emissions to net zero. The actions proposed include ecosystem restoration, planting new areas of woodland, capturing carbon in soils, and reducing demand for meat and dairy.
This report from the UK’s Office for National Statistics estimates the value of ten ecosystems services provided by natural capital in Scotland. Information on agricultural biomass (including fish capture) and carbon sequestration may be of particular interest to FCRN readers.
This paper analyses how different agriculture and forestry activities affect biodiversity and carbon sequestration. In 2011, the top driver of losses to bird species richness was cattle production, while the greatest driver of losses to net carbon sequestration (relative to sequestration if natural vegetation were allowed to grow) was forestry.
In this report, the UK think tank Green Alliance argues that land-based carbon credits could be incorporated into a ‘Natural Infrastructure Scheme’ (NIS), a scheme previously proposed by the Green Alliance.
Climate mitigation policies rarely account for the time lags associated with land-based greenhouse gas mitigation policies such as reforestation, bioenergy with carbon capture and storage (BECCS) or reduction of agricultural emissions, argues this paper, making it unlikely that commitments under the Paris Agreement will be met.
This commentary in Nature Sustainability discusses governance and initiatives for conserving and increasing soil organic carbon. Through a multi-stakeholder discussion group, the authors developed a global agenda for action on soil organic carbon.
This report outlines the outcomes of the 4 per 1000 Africa Symposium on Soils for Food Security and Climate, which discussed the links between soil health and climate in Africa.
This paper presents a ‘carbon benefits index’ to measure how land use change contributes to global carbon storage and reduction in greenhouse gas emissions. The index accounts for both the carbon that could be stored if the land were reforested, and the carbon emissions of producing the same food elsewhere.
So-called natural climate solutions in the United States (such as changing management of forests, grassland and agricultural land) could create annual emissions savings equivalent up to 21% of current US emissions according to this paper.
A recording of the launch of the report “Negative Emissions Technologies and Reliable Sequestration: A Research Agenda” can be viewed here, hosted by the National Academies of Sciences, Engineering, and Medicine. The video is around one hour long and includes an overview of the report’s findings and a question-and-answer session.
US-based consulting firm Breakthrough Strategies & Solutions has created a list of recent papers, reports, conferences, media items, jobs and other resources on the topics of soil health and soil carbon sequestration.
A recent paper uses data from three countries (Ghana, Mexico and Poland) to determine whether more carbon can be kept in above-ground stocks by land sparing (increasing farms yields to minimise the conversion of natural habitats to farmland) or land sharing (increasing carbon stocks on farms, at the cost of converting more natural habitat to farmland because of lower yields). Land sparing maintained the highest above-ground carbon stocks in all cases studied.
Managing tropical forest conservation on the basis of maximising carbon storage might not protect the most biodiverse regions of forest, according to a recent paper. Using datasets from Brazil, the authors found that the correlation between biodiversity and levels of carbon stored in forests depended on whether and how the forest had been disturbed by human activity.
This book, by Klaus Lorenz and Rattan Lal, discusses the present state of knowledge on soil carbon dynamics in different types of agricultural systems, including croplands, grasslands, wetlands and agroforestry systems. It also discusses bioenergy and biochar.
A recent paper assesses the carbon implications of converting Indonesian rainforests to oil palm monocultures, rubber monocultures or rubber agroforestry systems (known as “jungle rubber”). It finds that carbon losses are greatest from oil palm plantations and lowest from jungle rubber systems, in all cases being mainly from loss of aboveground carbon stocks. The paper points out that, “Thorough assessments of land-use impacts on resources such as biodiversity, nutrients, and water must complement this synthesis on C but are still not available.”
