Inside Climate News: Politicians Are Considering Paying Farmers to Store Carbon. But Some Environmental and Agriculture Groups Say It’s Greenwashing

"In a letter to Congress, the groups ask lawmakers to vote against a proposal that would offer farms credits for conserving carbon or reducing their greenhouse gas emissions."

Paulo, Carlos; et al. (2021): Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization

Paulo, Carlos; Power, Ian M.; Stubbs, Amanda R.; Wang, Baolin; Zeyen, Nina; Wilson, Siobhan A. (2021): Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization. In Applied Geochemistry, p. 104955. DOI: 10.1016/j.apgeochem.2021.104955.

"We have developed a new method to evaluate the reactivity of mineral feedstocks that consists of a batch leach test using CO2 coupled with total inorganic carbon (TIC) analysis to quantify easily extractable Mg and Ca from non-carbonate (desirable) cation sources."

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."

Brazzola, Nicoletta; et al. (2021): Offsetting unabated agricultural emissions with CO2 removal to achieve ambitious climate targets

Brazzola, Nicoletta; Wohland, Jan; Patt, Anthony (2021): Offsetting unabated agricultural emissions with CO2 removal to achieve ambitious climate targets. In PloS one 16 (3), e0247887. DOI: 10.1371/journal.pone.0247887.

"We explore using additional CDR to offset alternative agricultural non-CO2 emission pathways in which emissions either remain constant or rise. We assess the effects on the climate of calculating CDR rates to offset agricultural emission under two different approaches: relying on the 100-year global warming potential conversion metric (GWP100) and maintaining effective radiative forcing levels at exactly those of RCP2.6."

AG Week: When it comes to carbon markets, farmers should have plenty of questions

"The rules for existing programs, which are being driven largely by corporate commitments to offset greenhouse gas emissions, can vary wildly on such issues as whether farmers will get paid based on their farming practices or for the amount of carbon they keep out of 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."

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)."

Los Angeles Times: A strike against global warming or a Big Ag giveaway?

"The uneven evidence supporting the climate promises of carbon bank proponents, who include Agriculture Secretary Tom Vilsack and top environmental advisors in the Biden administration, is raising red flags among some climate economists and other sustainability experts. They worry that what the administration is pitching as a bold step to confront warming could turn into a giveaway to Big Ag."
