Dirt: The Erosion of Civilizations (Hardcover)

by David R. Montgomery (Author)

Editorial Reviews

From Publishers Weekly
Montgomery (King of Fish), a geomorphologist who studies how landscapes change through time, argues persuasively that soil is humanity's most essential natural resource and essentially linked to modern civilization's survival. He traces the history of agriculture, showing that when humans exhausted the soil in the past, their societies collapsed, or they moved on. But moving on is not an option for future generations, he warns: there isn't enough land. In the U.S., mechanized agriculture has eroded an alarming amount of agricultural land, and in the developing world, degraded soil is a principal cause of poverty. We are running out of soil, and agriculture will soon be unable to support the world's growing population. Chemical fertilizers, which are made with lots of cheap oil, are not the solution. Nor are genetically modified seeds, which have not produced larger harvests or reduced the need for pesticides. Montgomery proposes an agricultural revolution based on soil conservation. Instead of tilling the land and making it vulnerable to erosion, we should put organic matter back into the ground, simulating natural conditions. His book, though sometimes redundant, makes a convincing case for the need to respect and conserve the world's limited supply of soil. Illus. not seen by PW. (May)

4.0 out of 5 stars What you never knew about history, August 28, 2007

By	Deborah Meckler - See all my reviews (REAL NAME)

While David R. Montgomery goes on a bit long and repetitively about how and why and where and how fast soils erode, the more interesting part of the book is the new look at history--why the Romans sought new lands to conquer, how Thomas Jefferson tried and failed to get widespread adoption of contour plowing, how the depletion of the southeast's agricultural soils provided yet more impetus for the Civil War, how even in ancient times writers urged soil husbandry, yet were largely ignored as they still are today, how monoculture, slavery and now industrialized agriculture speed up the process by which land will become unable to sustain growing human populations. It's a sobering message that we ignore at our children's peril.

5.0 out of 5 stars The demise of soil, September 13, 2007

By	John E. Vidale "conventional Earth scientist" (Seattle, WA USA) - See all my reviews (REAL NAME)

Policy makers at all levels as well as concerned citizens should take Dave's lessons to heart. In addition, this is THE book for the layman wondering anything about dirt's role in human history and its fate.

With unrelenting precision, Dave builds the case-by-case history of civilizations misusing the dirt to their ultimate misfortune. As a top-flight scientist and admirable philosopher, he lays bare the storyline of people first using dirt modestly, then disturbing and losing their topsoil in dozens of cases spanning the globe and ranging from pre-history to the present.

The progression of dirt degradation becomes very familiar by the end - one wonders how many more times and on what grand scale the failures will again become apparent.

A caveat - Dave is a colleague of mine, as well as an entertaining pop-folk guitar, who leads with guitar and vocals the local band "Big Dirt".

4.0 out of 5 stars A history of farming and its long-term legacy, March 15, 2008

By	Newton Ooi (Phoenix, Arizona United States) - See all my reviews (TOP 1000 REVIEWER)    (REAL NAME)

Though the title says Dirt, it should actually say Soil, as this book is about how numerous civilizations destroyed themselves by adopting unsustainable farming practices that eventually destroyed their land. The author examines the histories of England, Roman Empire, ancient Greece, pre-colonial Ethiopia, Mesopotamia, Pharaoic Egypt, continental Europe, Communist Russia, the antebellum South, Colonial New England, and China. The conclusions he draws from all are the same, agricultural practices driven by short-term profit led to long-term soil erosion and depletion. The latter created poverty, inducing emigrations, which led to civil strife, war, and gradual collapse. So this book does live up to its subtitle, it is a history of human civilization as told from the viewpoint of soil erosion.

As a work of nonfiction, its contents apply well to history, economics, geology, ecology, and anthropology, along with agriculture. As a commentary, it is quite objective and its points are well-conveyed. As reading material; it flows quite nicely and the chapters are easy to digest. A great book overall.
