Lefebvre, David; et al. (2020): Modelling the potential for soil carbon sequestration using biochar from sugarcane residues in Brazil

Lefebvre, David; Williams, Adrian; Meersmans, Jeroen; Kirk, Guy J. D.; Sohi, Saran; Goglio, Pietro; Smith, Pete (2020): Modelling the potential for soil carbon sequestration using biochar from sugarcane residues in Brazil. In Sci Rep 10 (1), p. 19479. DOI: 10.1038/s41598-020-76470-y.

"Sugarcane (Saccharum officinarum L.) cultivation leaves behind around 20 t ha−1 of biomass residue after harvest and processing. We investigated the potential for sequestering carbon (C) in soil with these residues by partially converting them into biochar (recalcitrant carbon-rich material)."

Project: ConserWater

"Using our AIs, we are launching the world's first international soil carbon market where corporations, governments and individuals can pay to offset their carbon dioxide emissions, and farmers can get paid to increase their soil carbon levels."

Varney, Rebecca M.; et al. (2020): A spatial emergent constraint on the sensitivity of soil carbon turnover to global warming

Varney, Rebecca M.; Chadburn, Sarah E.; Friedlingstein, Pierre; Burke, Eleanor J.; Koven, Charles D.; Hugelius, Gustaf; Cox, Peter M. (2020): A spatial emergent constraint on the sensitivity of soil carbon turnover to global warming. In Nat Comms 11 (1), p. 5544. DOI: 10.1038/s41467-020-19208-8.

"Here, we present a constraint on ΔCs,τ, which makes use of current heterotrophic respiration and the spatial variability of τs inferred from observations. This spatial emergent constraint allows us to halve the uncertainty in ΔCs,τ at 2 °C to −232 ± 52 PgC."

Phys.org: Warming of 2 C would release billions of tons of soil carbon

"The new international research study, led by the University of Exeter, reveals the sensitivity of soil carbon turnover to global warming and subsequently halves uncertainty about this in future climate change projections."

Wang, Jing; et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data

Wang, Jing; Feng, Liang; Palmer, Paul I.; Liu, Yi; Fang, Shuangxi; Bösch, Hartmut et al. (2020): Large Chinese land carbon sink estimated from atmospheric carbon dioxide data. In Nature 586 (7831), pp. 720–723. DOI: 10.1038/s41586-020-2849-9.

"Here we present recently available data on the atmospheric mole fraction of CO2, measured from six sites across China during 2009 to 2016. Using these data, we estimate a mean Chinese land biosphere sink of −1.11 ± 0.38 petagrams of carbon per year during 2010 to 2016, equivalent to about 45 per cent of our estimate of annual Chinese anthropogenic emissions over that period."

The Millbrook Independent: The Futility of Soil Carbon Sequestration

"For a long time, farmers have realized that soil organic matter improves the quality of soils, by improving water-hold capacity, friability, and nutrient content. But, however we do it—fertilization, irrigation, manuring, reduced tillage, and planting cover crops—increasing soil organic matter doesn’t look like such a good idea to mitigate climate change. The chemistry of humus substances includes a substantial amount of nitrogen and phosphorus that will limit our efforts."

Strassburg, Bernardo B. N.; et al. (2020): Global priority areas for ecosystem restoration

Strassburg, Bernardo B. N.; Iribarrem, Alvaro; Beyer, Hawthorne L.; Cordeiro, Carlos Leandro; Crouzeilles, Renato; Jakovac, Catarina C. et al. (2020): Global priority areas for ecosystem restoration. In Nature. DOI: 10.1038/s41586-020-2784-9.

"Here we develop and apply a multicriteria optimization approach that identifies priority areas for restoration across all terrestrial biomes, and estimates their benefits and costs. We find that restoring 15% of converted lands in priority areas could avoid 60% of expected extinctions while sequestering 299 gigatonnes of CO2—30% of the total CO2 increase in the atmosphere since the Industrial Revolution."

World Resources Institute: INSIDER: Further Explanation on the Potential Contribution of Soil Carbon Sequestration on Working Agricultural Lands to Climate Change Mitigation

"Implemented in the right way, preserving the huge, existing reservoirs of vegetative and soil carbon in the world’s remaining forests and woody savannas by boosting productivity on existing agricultural land (a land sparing strategy) is the largest, potential climate mitigation prize of regenerative and other agricultural practices."
