In his recent interview with Allan Savory, the high profile biologist and farmer who argues that properly managing grazing animals can counter climate chaos, George Monbiot reasonably asks for proof. Where I believe he strays into the unreasonable, is in asserting that there is none.
Savory’s argument, which counters popular conceptions, is that more livestock rather than fewer can help save the planet through a concept he calls “holistic management.” In brief, he contends that grazing livestock can reverse desertification and restore carbon to the soil, enhancing its biodiversity and countering climate change. Monbiot claims that this approach doesn’t work and in fact does more harm than good. But his assertions skip over the science and on the ground evidence that say otherwise.
Richard Teague, a range scientist from Texas A&M University, presented in favour of Savory’s theory at the recent Putting Grasslands to Work conference in London. Teague’s research is finding significant soil carbon sequestration from holistic range management practices.
Soil scientist, Dr Elaine Ingham, a microbiologist and until recently chief scientist at Rodale Institute, described how healthy soil, the underpinning of civilization throughout history, is created in interaction between grazing animals and soil microbiology. Peer-reviewed research from Rodale has shown how regenerative agriculture can sequester more carbon than humans are now emitting. Scientists, as well as dozens of farmers, ranchers and pastoralists from around the world, describe how they are increasing the health of their land, the carrying capacity of it, its biodiversity, and its profitability, all while preserving their culture and traditions.
How much carbon can be sequestered in properly managed grasslands and how fast? We don’t know, but we do know that massive carbon reserves were present in the ten-foot thick black soil of the historic grasslands of the Great Plains of the US. We know that the globe’s grasslands are the second largest store of naturally sequestered carbon after the oceans. They got that way by co-evolving with pre-industrial grazing practices: sufficient herds of native graziers, dense packed by healthy populations of predators.
