A new study from Colorado State University's Dept. of Soil & Crop Sciences & the Graduate Degree Program in Ecology found “that #regenerative practices—including integrating crop & livestock systems—were successful as long-term #CarbonStorage solutions.”
🧵 1/7
Researchers conducted a “global systematic meta-analysis of the effects of #regenerative management practices on Soil Organic Carbon (#SOC), Particulate Organic Carbon (#POC) & Mineral-Associated Organic Carbon (#MAOC) in cropland.”
2/
They found that:
1️⃣ “no-till (NT) and cropping system intensification increase #SOC (11.3% and 12.4%, respectively), #MAOC (8.5% and 7.1%, respectively), and #POC (19.7% and 33.3%, respectively) in topsoil (0 to 20 cm), but not in subsoil (>20 cm).” 3/
2️⃣ “experimental duration, tillage frequency, the intensification type, and rotation diversity moderate the effects of #RegenerativeManagement.” 4/
3️⃣ “NT synergized with integrated crop–livestock (ICL) systems to greatly increase #POC (38.1%) and cropping intensification synergized with ICL systems to greatly increase #MAOC (33.1 to 53.6%).” 5/
👆🏻“This analysis shows that #RegenerativeAgriculture is a key strategy to reduce the soil C deficit inherent to agriculture to promote both soil health and long-term C stabilization.”

The paper, "Restoring particulate and mineral-associated organic carbon through regenerative agriculture," was recently published in Proceedings of the National Academy of Sciences (@PNASNews). Read here ⬇️ pnas.org/doi/10.1073/pn…
Recent study present an analysis of “the gap between the CO2 storage required to meet net zero targets and the slow maturation of regional storage resources.”
Researchers estimate that “European storage rates need to boost 30-100x by 2030 to meet #NetZero by 2050. 🇨🇳 & North America face a similar challenge. The slow global progress of #CarbonStorage undermines the latest IPCC, IEA & EU transition pathways to net zero by 2050.”

🚨NEW STUDY🚨
“Given the high expectations placed on #DAC for future #decarbonisation, recent study presents an extensive review of DAC tech, exploring a number of techno-economic aspects, including an updated collection of the current & planned DAC projects around the world.”
🧵
“A dedicated analysis focused on the production of synthetic methane, methanol, and diesel from #DAC and electrolytic hydrogen in the European Union (EU) is also performed, where the #carbonfootprint is analysed for different scenarios and energy sources.”
2/10
The results show that “the maximum grid carbon intensity to obtain #NegativeEmissions with #DAC is estimated at 468 gCO 2 e/kWh, which is compliant with most of the EU countries’ current grid mix.”
3/10
The study, published in @Nature, “is the first of its kind to show the sustained benefits of tree diversity on a large spatial scale, in terms of #storing#carbon and nitrogen in the soil. It reinforces the importance of biodiversity conservation in forests.”
2/8
The researchers analyzed “Canada's National Forest Inventory database & used statistical modeling to provide new evidence of a link between greater tree diversity & higher soil C & N accumulation in natural forest ecosystems over decadal time scales.”
