Soil4Climate is happy to announce our updated science
compendium of peer-reviewed papers showing the potential of well-managed grazing as a practice for nature-positive protein production and climate change mitigation.
The findings are revealed through indicators such as improved soil carbon, soil nitrogen, and water retention. This update includes new studies by Rowntree, Mosier, Spratt, and Wang. Particularly exciting is
Rowntree et al. 2020,
Ecosystem Impacts and Productive Capacity of a Multi-Species Pastured Livestock System. This did a 20 year assessment of "holistic planned grazing" at White Oak Pastures farm in Clay County, Georgia, USA. It found an average soil C drawdown
of 2.29 Mg/ha/yr or 0.92 tC/ac/yr.
Teague et al. 2016,
The role of ruminants in reducing agriculture's carbon footprint in North America, showed
3tC/ha/yr or 1.2 tonnes C/ac/yr. He also shows that a combination of conservation cropping and Adaptive Multi-paddock (AMP) grazing could sequester
1.2 GtC/yr in North America. For context, this equates to 66% of US annual emissions. EPA inventory,
here.
With this update, we've also added key figures from select papers. This should be considered a living document, and we will continue to make improvements.
Please feel free to review and share your thoughts.
Best regards,
