“Grass, Soil, Hope, A Journey through Carbon Country,” by Courtney White (Chelsea Green, 2014), is an interesting and inspiring read. Did you know that San Francisco Bay wetlands had the potential to capture over 15 tons of carbon dioxide per acre each year, or that there were up to 400 million beaver in North America before European arrival, some 50 beaver for every mile of stream?
It may come as a surprise to some that, by design, White does not address carbon capture by forests, so-called “green carbon,” in this book. Yet, in the broadest sense, he does, since the core topic of his book is the capacity of growing vegetation, whether rangeland grasses or emergent wetland vegetation, or farmed landscapes, to capture atmospheric CO2. Soil carbon only becomes such as the end product of a process that begins with the capture of atmospheric carbon dioxide by the photosynthesizing green leaf. But because soils do indeed hold greater-much greater- capacity than standing forests to store carbon, White chooses, rightly, to focus on what he calls “brown carbon;” the carbon sequestered in the soil’s organic matter.
White’s thoughtful book includes philosophical ramblings among down-cutting arroyos and restored mountain streams, explicitly evoking the foundational land ethic of Aldo Leopold, Wendell Berry, and others; at one point White describes an eroding abandoned roadbed as a “crime scene.” From the rooftop farms of New York City to the restoration of wetlands 6 feet below sea level in New Orleans, to a revitalized 7000 foot high meadow in the mountains of New Mexico, White describes an astonishing array of real world responses to addressing –and reversing- climate change through the mechanism of soil carbon sequestration.
Through the concept of querencia. White explores the potent, if naïve enthusiasm of the “new agrarianism,” and dives into the depth, history and knowledge of the old agrarianism. He defines and explores the significance of agrivoltaics, and delineates the benefits of “planned grazing” for biodiversity, soil carbon, and climate.
Finally, White poses this challenge to the world; can we double the world’s soil carbon content to avert the worst ravages of climate change and reap the rewards of a carbon-rich soil ecology while there is still time? White shows how a mere 2% of the US population, using 2% of the nation’s GDP could do just that, while revealing the deep democracy of carbon-rich soils.
There is a deep humility in “Grass, Soil, Hope.” White honors the pioneers, radical thinkers and land stewardship outliers who are leading the way into a bold new carbon-based cultural-ecology, while at the same time he makes it clear that we all live in Carbon Country, and indeed always have.
While taking a clear-eyed look at the work -and dangers- that lie ahead, White paints a hopeful picture with a remarkably variable collection of tales of success. Well worth the read, let us hope that the stories that inspired White to write the book will encourage all of us to follow him, clear-eyed, into our future as responsible stewards of Carbon Country.
