Book excerpt: Once the grain basket for South Africa, much of Lesotho has become a scarred and treeless wasteland. The nation's spectacular gullying has concerned environmentalists and conservationists for more than half a century, In Imperial Gullies: Soil Erosion and Conservation in Lesotho, Kate B. Showers documents the truth behind this devastation. Showers reconstructs the history of the landscape, beginning with a history of the soil. She concludes that Lesotho's distinctive erosion chasms, called dongas, often cited as an example of destructive land-use practices by African farmers, actually were caused by colonial and postcolonial practices. The residents of Lesotho emerge as victims of a failed technology. Their efforts to mitigate or resist implementation of destructive soil conservation engineering works were thwarted, and they were blamed for the consequences of policies promoted by international soil conservationists since the 1930s. Imperial Gullies calls for an observational, experimental and, most importantly, a fully consultative and participatory approach to address Lesotho's serious contemporary problems of soil erosion. The first book to bring to center stage the historical practice of colonial soil science and a cautionary tale of western science in unfamiliar terrain it will interest a broad, interdisciplinary audience in African and environmental studies, social sciences, and history. "Showers shows how local people understood that colonial contour conservation methods and road building actually stimulated gully erosion, something colonial scientists failed to realize. Overall it is undoubtedly one of the most important books written to date on any part of the environmental history of Africa. Moreover it stands out in the discipline of environmental history in general as an unusually sophisticated work of great insight and explanatory power."---Richard H.
