The Science Behind Holistic Management BY ANN ADAMS
D
espite over 40 years of thousands of people practicing Holistic Management around the world on over 40 million acres and numerous scientific, peer-reviewed studies, there are still some people who want to detract from the results achieved by Holistic Management practitioners and ignore the science behind why it works. A disappointing article (http://bit. ly/2rb1spd) in the March 2017 Sierra Magazine focused mostly on making disparaging comments about Allan Savory and trotting out the same detractors and their articles about why Holistic Management is not backed by science. Having read similar articles over the past 20 years, I was amazed that there was no attempt to report on the numerous scientific studies that have emerged in the past 5–10 years that actually do scientifically document the results of Holistic Management practitioners as well as all the studies that do show how good livestock management can lead to soil health and how soil health is tied to carbon and methane sequestration. While there are a host of scientific papers, there are a few scientists that have focused much of their research to demonstrate the science behind how Holistic Planned Grazing (or Adaptive Multi-Paddock Grazing) does improve soil health that I would like to highlight in the hopes that more people will read their work. One person doing this type of research is soil scientist Dr. Christine Jones from Australia with much of her research available on her website (http://www.amazingcarbon.com/). There are a number of different articles well worth reading on that site, as well as an article “Soil carbon —can it save agriculture’s bacon?” in which she discussed the research done by Dr. Mark Adams from the University of Sydney regarding the soil’s ability to sequester methane. With improved grazing, comes the land’s greater capability of sequestering more carbon creating
the opportunity for Holistic Planned Grazing to be carbon positive. Another scientist involved in this type of research is Dr. Richard Teague from Texas A&M Agrilife. He has been involved in a number of different studies that he has undertaken with numerous other scientists focusing on Greenhouse Gas mitigation (http://bit.ly/1iM99tt) as well as an article (http://bit.ly/2rNcZYc) on the role of ruminants in reducing agriculture’s carbon that was co-authored with Dr. Rattan Lal of Ohio State University. He has also done specific research in Canada (https://yhoo.it/2rvgq9t) and Texas (http://bit.ly/2qe4sfR) comparing the increased carbon sequestration on land where people are practicing Holistic Planned Grazing in comparison to their neighbors who are not. On average in the Texas study the holistically grazed land added three tons of carbon/ha/ year more than the heavy continuously grazed neighboring land for an over 30% increase in carbon sequestration. Scientist Dr. Keith Weber from Idaho State University has also shown how Holistic Planned Grazing improves soil moisture retention on semi-arid rangelands (http://bit.ly/2qjAlrX). This water retention leads to more plant growth which
As more people practice Holistic Management, more government and non-profit agencies are eager to partner with Holistic Management practitioners focused on improving land health and biodiversity. One of HMI’s partners is The Nature Conservancy. To learn more about how these two organizations are working together, turn to page 2.

increases soil carbon and thus carbon sequestration. In addition, there are other qualitative studies that show the improved profitability and sustainability of holistically managed operations and the efficacy of Holistic Management as a whole farm/ranch planning tool. In particular, Dr. Deborah Stinner, Dr. Benjamin Stinner of (Ohio State University at Wooster), and Ed Marsolf wrote an article (http://bit.ly/2qQlfYh) about Holistic Management and how biodiversity is an organizing principle in agroecosystem management. Another qualitative study (http:// bit.ly/2qbdtXN) was done by Charley Orchard as he surveyed ranchers in the Northern Rockies and analyzed the numerous benefits they had achieved. With more people practicing Holistic Management around the world, there is more evidence of the positive effects it has on the land, the businesses, and the people. In turn, as we face growing environmental challenges, researchers are turning their attention to practices that work and trying to better understand them. That is why we are pleased to be partnering with The Nature Conservancy as they work to share their knowledge of how Holistic Management is an effective, sciencebased conservation tool.
