Tropical rain forest is being cleared so rapidly and on such a scale that it is a major global environmental problem, threatening the survival of half of the world's plant and animal species and contributing to global climate change through the greenhouse effect. But, despite widespread concern for over twenty years, only limited progress has been made in controlling deforestation and improving forest management in the humid tropics.
In this book Alan Grainger offers afresh analysis of the causes of deforestation and presents an integrated strategy for controlling it. His strategy embraces agriculture, forestry and conservation and stresses the need for changes in government policies if land use is to be made more sustainable and the underlying causes of the problem are to be addressed. Controlling Tropical Deforestation is essential reading for policy makers, agronomists, foresters, conservationists and development professionals. To general readers and students on introductory courses at schools and universities it also offers the first concise but comprehensive overview of the causes, scale and consequences of deforestation. Alan Grainger is a lecturer in geography at the University of Leeds. He is author of The Threatening Desert: Controlling Desertification, also published by Earthscan. Originally published in 1992
