Leger, Dorian; et al. (2021): Photovoltaic-driven microbial protein production can use land and sunlight more efficiently than conventional crops

Leger, Dorian; Matassa, Silvio; Noor, Elad; Shepon, Alon; Milo, Ron; Bar-Even, Arren (2021): Photovoltaic-driven microbial protein production can use land and sunlight more efficiently than conventional crops. In Proceedings of the National Academy of Sciences of the United States of America 118 (26). DOI: 10.1073/pnas.2015025118.

"Here, we analyze the efficiency associated with using solar energy for converting atmospheric CO2 derived from direct air capture into microbial biomass that can feed humans and animals."

Phys.org: A brighter future: How whitening the Wheatbelt could cool the climate

"Like an enormous mirror, those crops bounce solar radiation back out to space. That means WA's Wheatbelt—and the wheat growing there—could become a crucial part of how southwestern WA adapts to climate change."

NBC News: Carbon storage offers hope for climate, cash for farmers

"All industries are under pressure to reduce emissions, primarily by switching to renewable energy. Farming has something most others don’t: the ability to pull carbon dioxide."

Fan, Yuanchao; et al. (2021): Solar geoengineering can alleviate climate change pressures on crop yields.

Fan, Yuanchao; Tjiputra, Jerry; Muri, Helene; Lombardozzi, Danica; Park, Chang-Eui; Wu, Shengjun; Keith, David (2021): Solar geoengineering can alleviate climate change pressures on crop yields. In Nat Food 2 (5), pp. 373–381. DOI: 10.1038/s43016-021-00278-w.

"Using an advanced crop model within an Earth system model, we analysed the yield responses of six major crops to three SG technologies (SGs) and emissions reduction when they provide roughly the same reduction in radiative forcing and assume the same land use."

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."
