Botswana: Tracking wildlife in the Kalahari with a PDA

Louis Liebenberg discusses how CyberTracker software is helping a community in Botswana to monitor and manage local wildlife resources

Tracking science : an alternative for those excluded by citizen science

Abstract: In response to recent discussion about terminology, we propose “tracking science” as a term that is more inclusive than citizen science. Our suggestion is set against a postcolonial political background and large-scale migrations, in which “citizen” is becoming an increasingly contentious term. As a diverse group of authors from several continents, our priority is to deliberate a term that is all-inclusive, so that it could be adopted by everyone who participates in science or contributes to scientific knowledge, regardless of socio-cultural background. For example, current citizen science terms used for Indigenous knowledge imply that such practitioners belong to a sub-group that is other, and therefore marginalized. Our definition for “tracking science” does not exclude Indigenous peoples and their knowledge contributions and may provide a space for those who currently participate in citizen science, but want to contribute, explore, and/or operate beyond..

Fatal Human Infection with Rabies-related Duvenhage Virus, South Africa

Duvenhage virus was isolated from a patient who died of a rabieslike disease after being scratched by a bat early in 2006. This occurred ≈80 km from the site where the only other known human infection with the virus had occurred 36 years earlier

The Art of Tracking : the Origin of Science

In a work of painstaking and wide-ranging scholarship, backed up by fieldwork among the Kalahari hunter-gatherers, Louis Liebenberg explains how the art of tracking represents a crucial step in human evolution. Liebenberg examines the principles of tracking, and the classification and interpretation of spoor under difficult conditions. He also shows how the original speculative hypotheses of early hunter-gatherers have a direct line to the propositions of modern physicists who track " sub-atomic particles. In the book, the author argues that the art of tracking involves the same intellectual and creative abilities as physics and mathematics, and may therefore represent the origin of science itself. The book has been hailed as a real contribution to our understanding of the complexity involved in the process by which indigenous peoples track and hunt animals. It is insightful, detailed and well articulated. Highly original work: This is indeed a highly original and multi-disciplinary work fuelled with the obvious passion the author has for his subject. Liebenberg delves first into the evolution of hunter-gatherer subsistence, tracing our four-million-year hominid history to analyse the evolution of subsistence and the emergence of tracking as a primary tool in that subsistence. This, he suggests, is the first attempt at science and a scientific discipline and that a study of its origins and development can clarify the development of the current constructs of the human scientific mind. Similarities to modern science: Part two of The Art of Tracking further develops this theme with an analysis of current hunter-gatherer subsistence in Botswana and Namibia's Kalahari and, in particular, the role and development of tracking in this environment and culture. The third and final section examines the "fundamentals of tracking" such as the classification of spoor, its interpretation, the basic principles of following spoor and the similarities of these, in terms of intellectual and creative abilities, to modern science. The Art of Tracking provides an essential companion to any of Liebenberg's field guides on the subject of tracking and whether or not you subscribe to the book's hypothesis, it is fascinating and stimulating reading and fitting testament to Louis Liebenberg's own contribution to the science of tracking.
