Article Effects of livestock grazing on grassland carbon storage and...
Hello Dr Zhou,
Your paper seems to contradict what good ranchers and farmers tell us....
Specifically, grazing significantly decreased aboveground plant C pool (APCP), belowground plant C pool (BPCP), soil C pool (SCP), and Rs by 19.1%, 6.4%, 3.1%, and 4.6%, respectively, while overall effects of all global climate change factors increased APCP, BPCP and Rs by 6.5%, 15.3%, and 3.4% but had no significant effect on SCP.
Properly managed "mob grazing" is the fastest method of sequestering soil organic carbon is my general understanding from the literature and especially internet discussion. I guess some of your studies are related to bad grazing management.

Hello Mr. Zhou,
what else should the grassland of the studies be used for? Should it be mowed and used up as fodder in livestock stables only (which leads to other climate-change relevant and ethical questions)? I guess the majority of your sites are not stable state and no management would lead to soil-C decreases as well (see Gou et al. 2002). Did you consider alternative land use? And how should the vast C-storages of many grasslands be originated if not by the help of browsing herbivores (helping to avoid successional processes)?
Any ideas?
All the best!

The experience of ranchers and producers is now becoming widely published. Gabe Brown has written a book "Dirt to soil: One family's journey into regenerative agriculture". It is published by Chelsea Green, ISBN 9781603587631.
Greg Judy has also been speaking at a number of venues. Transcripts of his talks are included in prospective learning materials that are attached.

We now have authoritative reports in the UK endorsing agro-ecology and "deferred mob grazing" - see attached.
In Latin America there is a strong recommendation for regenerative grazing, with the Savory Institute now having certification standards for "regenerative and organic" production. In Africa, recommended practice tends to be silvo-pastural development.
I recommend working with organizations truly representing rural interests like "Soils for Life" in NSW Australia.
