1991014917Oxford: Blackwell Scientific Publications 1991. A few illustrations quarto pp xii 221 limp covers a very good copy. This volume is the fifth in a series of publications produced over the last five years on the ecology of tropical savannas. The volumes arise from work undertaken by the Responses of Savannas to Stress and Disturbance RSSD Program under the auspices of the International Union of Biological Sciences IUBS Decade of the Topics Programme co-sponsored by the UNESCO Man and the Biosphere MAB Program. Savannas cover just under one third of the world's land surface and contain a large and rapidly growing proportion of the world's population as well as the majority of its rangelands and livestock. Most savannas are experiencing increasing pressures from demographic and economic changes that have increased dramatically over the past few decades. In addition to the changing patterns in demography and economics the forecasts of global warming further alert us to the most important challenge - to conserve and manage wisely the savanna ecosystems of the world and it is this which forms the basis of the work of the RSSD Program through the promotion of scientific research and communication. This fifth publication is comprised of research papers presented at the RSSD's international symposium held in Darwin Australia in 1988. The papers address the Australian perspective and intercontinental comparisons and come from an international expert authorship. First Edition. Soft Cover. Very Good.
