Recovery of a tropical forest with maximum carbon content can take hundreds of
years (Montagnini and Nair 2004). Some tropical countries have recently started
programs of incentives to encourage tree plantation development to help offset C
emissions. Since 1966, Costa Rica has contributed payments for environmental
services (ES) such as promoting forest conservation, sustainable forest
management, and tree plantations through the assignment of differential
incentives for each ...

Tropical Forests of the Guiana Shield

Ancient Forests in a Modern World

The Guiana Shield is an ancient geological formation located in the northern part of South America, covering an area of one million square kilometres. Despite its hostile environment, it is home to many unusual and highly specialized plants and animals, which constitute a rich area of biodiversity. Chapters in this book include hydrology, nutrient cycling, forest phenology, insect-plant interactions, forest microclimate, plant distributions, forest dynamics and conservation and management of flora and fauna. It provides a comprehensive and detailed review of the ecology, biology and natural history of the forests of the area.

Changes and Disturbance in Tropical Rainforest in South-East Asia

Views on the dynamics of tropical forests are changing rapidly with the recognition that their environment is variable on the decadal to century scale. Fluctuating climatic conditions partly determine tropical forest structure, species composition and dynamics. Tropical communities are also highly contingent in space and time with respect to site and historical factors. Tropical forests have experienced to some degree this disturbance regime in the past, but climatologists are now predicting increasingly frequent extreme events in the new century. The combination of increasing deforestation and land-use conversion by man plus an increasingly variable environment means a situation that could be very difficult to manage.

Tropical Rain Forest: A Wider Perspective

The international perspective for this book is the unprecedented level of concern over deforestation, recognized by the meeting of world leaders at the 1992 Earth Summit, in Rio do Janeiro, and culminating in the appoint ment of the Intergovernmental Panel on Forests (IPF), under the auspices of the UN Commission on Sustainable Development. The wide range of issues covered by the authors in this volume reflects the breadth of the interna tional debate, from national policies and activist campaigning, through eco nomic and social objectives, to the sustainable management of forest and soil resources. Since the conservation campaigns of the 1980s, the focus of international concern has widened from tropical rain forests to all forest formations, in all regions, with increased recognition of global values and common responsibil ities. However, while forest cover in some temperate countries is increasing, irrational deforestation, at historically unprecedented levels of damage to biodiversity and to other environmental values, remains most acute in tropi cal countries, where the need to use the natural resources for sustainable development is greatest, and the capability weakest. While accepting the urgency of the situation, and the need for greater coherence of action at a global level, the 1997 report of the IPF to the UN Commission emphasized the powers and responsibilities of national governments, and the importance of National Forest Programmes, but with the fuller participation of local communities, and with enhanced access to international assistance.

The proliferation of rainforest conservation projects, and their apparent
indifference tothe actual culturesof forest people, can be illustrated from research
carried out inCameroon and Sierra Leone. These two countries represent,in
microcosm,almost allofthe ecological, sociocultural, colonial and postcolonial
processes which haveaffected theforest societies ofWestand CentralAfrica.
Ecologically, Sierra Leone andCameroon representthe Guinean and Congo

Timber Production and Biodiversity Conservation in Tropical Rain Forests

Timber production is often the most economic form of land use in areas of tropical forest; forest preservation is rarely so. This book attempts to bridge the current gap between conservation requirements and commercial interests, indicating the possibilities for integrated management of tropical forests. The aim is to create a practical approach for the management of production forest as a supplement to totally-protected forest in the conservation of tropical biodiversity.

PREFACE In the late 1970s, I was somewhat surprised to find myself conducting
the first detailed work on the ecological effects of timber logging in a tropical rain
forest. Surprised, that is, that so little had been conducted beforehand. Due
mainly to the medium of television, enormous public interest had been kindled
concerning the fate of the rain forests. In response to this interest, a flood of
popular and scientific books and articles reporting on the consequences of
tropical forest loss ...
