Botswana's fences and the depletion of Kalahari wildlife

Over the past 20 years or more fences have been erected around the part of the Kalahari that lies in Botswana without thought about the impact on the wildlife. Over the years the fences have taken a massive toll of animals whose traditional migration routes to water have been sealed off. The authors, who have been working in the Kalahari since 1981, examine the current situation and suggest some of the possible remedies that are so urgently needed.
