Chapter 3. Eroding Soils and Shrinking Cropland: Introduction
In 1938 and 1939, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture (USDA), traveled abroad to look at lands that had been cultivated for hundreds and even thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history. Others had failed to do so and left only remnants of their illustrious pasts.1
In a section of the report of his travels entitled "The Hundred Dead Cities," he described a site in northern Syria, near Aleppo, where ancient buildings were still standing in stark isolated relief, but they were on bare rock. During the seventh century, the thriving region had been invaded, initially by a Persian army and later by nomads out of the Arabian Desert. In the process, soil and water conservation practices used for centuries were abandoned. Lowdermilk noted, "Here erosion had done its worst....if the soils had remained, even though the cities were destroyed and the populations dispersed, the area might be re-peopled again and the cities rebuilt, but now that the soils are gone, all is gone."2
Now fast forward to a trip in 2002 by a U.N. team to assess the food situation in Lesotho, a tiny country imbedded within South Africa. Their finding was straightforward: "Agriculture in Lesotho faces a catastrophic future; crop production is declining and could cease altogether over large tracts of the country if steps are not taken to reverse soil erosion, degradation, and the decline in soil fertility." Michael Grunwald, writing in the Washington Post, reports that nearly half of the children under five in Lesotho are stunted physically. "Many," he says, "are too weak to walk to school."3
Whether the land is in northern Syria, Lesotho, or elsewhere, the health of people living on it cannot be separated from the health of the land itself. A large share of the world's 840 million hungry live on land where the soils are worn thin by erosion.4
