A celebrated biologist's manifesto addressing a soil loss crisis accelerated by poor conservation practices and climate change "Jo Handelsman is a national treasure, and her clarion call warning of a looming soil-loss catastrophe must be heard. Add her clearly written alarm to other future-shocks: climate change, pandemics, and mass extinctions."--Laurie Garrett, Pulitzer Prize winner and author of The Coming Plague: Newly Emerging Diseases in a World out of Balance "The ground beneath our feet is slipping away as we lose the precious soil that sustains us. Jo Handelsman's writing--as rich and life supporting as the soil itself--is a riveting warning."--Alan Alda, actor, writer, and host of the podcast Clear+Vivid with Alan Alda This book by celebrated biologist Jo Handelsman lays bare the complex connections among climate change, soil erosion, food and water security, and drug discovery. Humans depend on soil for 95 percent of global food production, yet let it erode at unsustainable rates. In the United States, China, and India, vast tracts of farmland will be barren of topsoil within this century. The combination of intensifying erosion caused by climate change and the increasing food needs of a growing world population is creating a desperate need for solutions to this crisis. Writing for a nonspecialist audience, Jo Handelsman celebrates the capacities of soil and explores the soil-related challenges of the near future. She begins by telling soil's origin story, explains how it erodes and the subsequent repercussions worldwide, and offers solutions. She considers lessons learned from indigenous people who have sustainably farmed the same land for thousands of years, practices developed for large-scale agriculture, and proposals using technology and policy initiatives.

Dirt, soil, call it what you want—it's everywhere we go. It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

Finalist for the PEN/E. O. Wilson Literary Science Writing Award "A call to action that underscores a common goal: to change the world from the ground up." —Dan Barber, author of The Third Plate For centuries, agricultural practices have eroded the soil that farming depends on, stripping it of the organic matter vital to its productivity. Now conventional agriculture is threatening disaster for the world’s growing population. In Growing a Revolution, geologist David R. Montgomery travels the world, meeting farmers at the forefront of an agricultural movement to restore soil health. From Kansas to Ghana, he sees why adopting the three tenets of conservation agriculture—ditching the plow, planting cover crops, and growing a diversity of crops—is the solution. When farmers restore fertility to the land, this helps feed the world, cool the planet, reduce pollution, and return profitability to family farms.

During the last twenty years, mutations within agricultural systems in France and Europe have brought on a spectacular worsening of soil erosion and degradation. This volume, contributed to by scientists from 25 countries, discusses how this risk can be evaluated, and which solutions should be adopted without radically disturbing the socio-economic orientation of major agricultural regions. It is an excellent starting point for the development of new research themes, and will be of great value to soil and environmental scientists, and to all those involved in land irrigation and drainage.

Sometimes called “black gold,” Iowa’s deep, rich soils are a treasure that formed over thousands of years under the very best of the world’s grasslands—the tallgrass prairie. The soils are diverse and complex and hold within them a record not only of Iowa’s prehistoric past, but also of the changes that took place after settlers utterly transformed the land, as well as the ongoing adjustments taking place today due to climate change. In language that is scientifically sound but accessible to the layperson, Kathleen Woida explains how soils formed and have changed over centuries and millennia in the land between two rivers. Its soils are what make Iowa a premier agricultural state, both in terms of acres planted and bushels harvested. But in the last hundred years, large-scale intensive agriculture and urban development have severely degraded most of our soils. However, as Woida documents, some innovative Iowans are beginning to repair and regenerate their soils by treating them as the living ecosystem and vast carbon store that they are. To paraphrase Aldo Leopold, these new pioneers are beginning to see their soils as part of a community to which they and their descendants belong, rather than commodities belonging to them.

This new volume is the first independent analysis of an important national data base, the National Resources Inventory. It cites potential uses of the NRI in controlling soil erosion; determining land use; deciding conservation treatment; classifying soils; and protecting groundwater quality. Methods for soil conservation activities, ranging from the ranking of the lands most susceptible to erosion to the measurement and prediction of both wind and water erosion, are recommended throughout the volume.
