Crystal-Ornelas, Robert; et al. (2021): Soil organic carbon is affected by organic amendments, conservation tillage, and cover cropping in organic farming systems: A meta-analysis

Crystal-Ornelas, Robert; Thapa, Resham; Tully, Katherine L. (2021): Soil organic carbon is affected by organic amendments, conservation tillage, and cover cropping in organic farming systems: A meta-analysis. In Agriculture, Ecosystems & Environment 312. DOI: 10.1016/j.agee.2021.107356.

"Therefore, the main objective of this meta-analysis was to investigate the effect of BMPs, such as organic amendments, conservation tillage, and cover cropping, on soil health within organic farming systems. We focused on two principal soil health metrics: soil organic carbon (SOC) and microbial biomass carbon (MBC) concentrations."

Spence, Elspeth; et al. (2021): Exploring cross-national public support for the use of enhanced weathering as a land-based carbon dioxide removal strategy

Spence, Elspeth; Cox, Emily; Pidgeon, Nick (2021): Exploring cross-national public support for the use of enhanced weathering as a land-based carbon dioxide removal strategy. In Climatic Change 165 (1-2). DOI: 10.1007/s10584-021-03050-y.

"This study explores how public attitudes across three countries influence support towards terrestrial enhanced weathering, whereby silicate minerals are applied to agricultural land to remove carbon dioxide from the atmosphere."

Horton, Peter; et al. (2021): Technologies to deliver food and climate security through agriculture

Horton, Peter; Long, Stephen P.; Smith, Pete; Banwart, Steven A.; Beerling, David J. (2021): Technologies to deliver food and climate security through agriculture. In Nature Plants 7 (3), pp. 250–255. DOI: 10.1038/s41477-021-00877-2.

"Here, we discuss a series of technological options to bring about change in agriculture for delivering food security and providing multiple routes to the removal of CO2 from the atmosphere. These technologies include the use of silicate amendment of soils to sequester atmospheric CO2, agronomy technologies to increase soil organic carbon, and high-yielding resource-efficient crops to deliver increased agricultural yield, thus freeing land that is less suited for intensive cropping for land use practices that will further increase carbon storage."

Soimakallio, Sampo; et al. (2021): On the trade-offs and synergies between forest carbon sequestration and substitution

Soimakallio, Sampo; Kalliokoski, Tuomo; Lehtonen, Aleksi; Salminen, Olli (2021): On the trade-offs and synergies between forest carbon sequestration and substitution. In Mitig Adapt Strat Glob Change 26 (1), pp. 1–17. DOI: 10.1007/s11027-021-09942-9.

"Forest biomass can be used in two different ways to limit the growth of the atmospheric greenhouse gas (GHG) concentrations: (1) to provide negative emissions through sequestration of carbon into forests and harvested wood products or (2) to avoid GHG emissions through substitution of non-renewable raw materials with wood. We study the trade-offs and synergies between these strategies using three different Finnish national-level forest scenarios between 2015 and 2044 as examples."

Medium: Addressing Climate Change through Soil Carbon: What is needed to align incentives?

"Much has been written about the potential disruptions, yet there is also an opportunity to act now to mitigate these disasters. Soil carbon’s role in this is nothing new, but the potential for the earth’s soil to sequester 100–150 billion tons of carbon from the atmosphere cannot be ignored(*1)."

Terlouw, Tom; et al. (2021): Life cycle assessment of carbon dioxide removal technologies: a critical review

Terlouw, Tom; Bauer, Christian; Rosa, Lorenzo; Mazzotti, Marco (2021): Life cycle assessment of carbon dioxide removal technologies: a critical review. In Energy & Environmental Science. DOI: 10.1039/D0EE03757E.

"We present a critical review on conducted Life Cycle Assessments (LCAs) of a comprehensive set of CDR technologies: afforestation and reforestation, biochar, soil carbon sequestration, enhanced weathering, ocean fertilisation, bioenergy with carbon capture and storage, and direct air carbon capture and storage."

Pellegrini, Adam F. A.; et al. (2021): Decadal changes in fire frequencies shift tree communities and functional traits

Pellegrini, Adam F. A.; Refsland, Tyler; Averill, Colin; Terrer, César; Staver, A. Carla; Brockway, Dale G. et al. (2021): Decadal changes in fire frequencies shift tree communities and functional traits. In Nat Ecol Evol, pp. 1–9. DOI: 10.1038/s41559-021-01401-7.

"Here, we address the overall effects of fire on tree communities and the factors controlling their sensitivity in 29 sites that experienced multi-decadal alterations in fire frequencies in savanna and forest ecosystems across tropical and temperate regions."

Cornell University: CALS Dean Ben Houlton may have a billion-ton solution to climate change

"In a nutshell, Houlton’s work involves capturing carbon from the sky and putting it into the soil, where it can remain locked up for thousands of years or longer. To do this, researchers are using recycled rock dust to enrich farm and rangeland soils, in order to accelerate natural weathering processes by which soils capture atmospheric carbon."
