Roy and Jan have assembled a timely snapshot of our current understanding of ecotourism, both as a concept worthy of scientific inquiry and as an increasingly significant segment of global commerce and industry. A terrific piece of work! Sam Ham, University of Idaho, US In the 30 or so year since it became established in the tourism literature and in tourism practice, ecotourism has attracted as many proponents as opponents. This Handbook now brings together some of the leading scholars worldwide in this field, to explore the current position of this form of tourism. In doing so, it offers serious critiques, it explores meanings and paradoxes, it offers best practices and it looks to the future. It is the Handbook for one of tourisms fastest growing and controversial sectors. David Airey, University of Surrey, UK This is a most welcome and needed book. With a very strong editorial team and contributing authors, the Handbook covers all the key issues of ecotourism. It cuts through the confusion surrounding the much-misunderstood concept of ecotourism, clearly dealing with definitions, concepts and research issues. The Handbook is particularly welcome for its focus on the visitor experience, a strength of the editors, and for clearly linking the theory of ecotourism with practice in the field. Christopher Cooper, Oxford Brookes University, UK This Handbook brings together contributions from over forty international experts in the field of ecotourism. It provides a critical review and discussion of current issues and concepts it challenges readers to consider the boundaries of what ecotourism is, and could be. The Handbook provides practical information regarding the business of ecotourism; insights into ecotourist behaviour and visitor experiences; and reflections on the practice of ecotourism in a range of different contexts. The Handbook is designed to be a valuable reference book for tourism scholars and researchers.

The natural resources of the Earth are indispensable for the survival of humans, plants, and animals and for the state of biodiversity. The way they are managed determines the extent to which they will be preserved for future generations. Climate change underscores the need for the proper use of natural resources. This book brings together reviews of literature and the results of research studies on the status and management of soil, water, plant, and wildlife resources, especially as they relate to the biological sciences, in Africa, Asia, Europe, North America, and Latin America. It covers work on classification and inventories, impacts of anthropogenic activities, and exploitation and conservation. The book will be of interest to scientists and practitioners of natural resource management worldwide.

Research Paper (postgraduate) from the year 2008 in the subject Forestry / Forestry Economics, Vrije University Brussel (Human Ecology Department), 52 entries in the bibliography, language: English, abstract: The role of medicinal plants in traditional health care delivery in Ghana cannot be overemphasized. More than 250 indigenous trees and plants with healing properties have been scientifically catalogued in Ghana. Unfortunately, the very foundation upon which the medicinal plant species and the traditional health care system survive is threatened by deforestation. The rate of deforestation has increased by 50% over the last ten years, according to the UN Food and Agriculture Organization (FAO). The current area of intact forest is now estimated at between 10.9 and 11.8% of the original cover and 6.9% of the country's total area. Deforestation is changing the habitats of disease-carrying insects and creating conditions that may help to spread malaria, river blindness and other devastating illnesses. Moreover, since the majority of the rural poor in Ghana depends on traditional medicine for their health care needs, the present high rate of deforestation will have a detrimental effect on the heath care delivery system in the country. Important plant species will be lost to deforestation unless urgent measures are taken. This paper examines the impact of deforestation on medicinal plants in Ghana.
