Once the grain basket for South Africa, much of Lesotho has become a scarred and degraded landscape. The nation’s spectacular erosion and gullying have 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 interventions. 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 important, 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.
The second largest order of mammals, Chiroptera comprises more than one thousand species of bats. Because of their mobility, bats are often the only native mammals on isolated oceanic islands, where more than half of all bat species live. These island bats represent an evolutionarily distinctive and ecologically significant part of the earth’s biological diversity.
Island Bats is the first book to focus solely on the evolution, ecology, and conservation of bats living in the world’s island ecosystems. Among other topics, the contributors to this volume examine how the earth’s history has affected the evolution of island bats, investigate how bat populations are affected by volcanic eruptions and hurricanes, and explore the threat of extinction from human disturbance. Geographically diverse, the volume includes studies of the islands of the Caribbean, the Western Indian Ocean, Micronesia, Indonesia, the Philippines, and New Zealand.
With its wealth of information from long-term studies, Island Bats provides timely and valuable information about how this fauna has evolved and how it can be conserved.
