In view of the rapidly changing ecology of Africa ,this work provides benchmarks for some of the major, and more neglected, aspects, with an accent on historical data to enable habitats to be seen in relation to their previous state, forming a background reference work to understanding how the ecology of Africa has been shaped by its past. Reviewing historical data wherever possible it adopts an holistic view treating man as well as animals, with accent on diseases both human and animal which have been a potent force in shaping Africa’s ecology, a role neglected in ecological studies.

Thomas Robert Malthus's reputation has lately been rehabilitated in the fields of social biology, demography, environmentalism, and economics. In the midst of this current interest and with the chance to mark the occasion of the bicentenary of the first edition of the Essay on Population (1798), the contributors to this volume take this timely opportunity to examine the historical conditions in which Malthus constructed his theory, and in which the concept of a 'Malthusian' and 'Neo-Malthusian' philosophy first emerged. The essays redress the balance between Malthus's original argument, the immediate responses to Malthus by medics and theologians in Britain and on the Continent, and some of the ways that his ideas were later attacked, appropriated, or misrepresented. Included here are essays that not only re-evaluate the development of Malthus's theory, but also offer critical perspectives on the generation of the 'Malthusian league' and debates about birth control in Britain and on the Continent, and Malthus's influence on the emergence of social science and Darwinian evolutionary biology.
