Book Description
After publication of the first volume of the Tropical Rain Forest, the International Journal of Mycology and Lichenology commented ``This is a welcome addition to the literature on the ecology of tropical rain forests. The book provides a wealth of data and stimulating discussions and is of great interest to ecologists interested in tropical areas.'' Whereas the first volume dealt with system-ecological aspects such as community organization and processes, the present volume concentrates on biogeographical aspects such as species composition, diversity, and geographical variation.Recent ecological research in the tropical rain forest has greatly extended our understanding of biogeographical patterns of variation in the various groups of organisms, and has revealed many of the ecological and evolutionary forces that led to the present patterns of variation. Many important systems of co-evolution between the tropical rain forest ecosystems have also come to light, and the loss of species and related damage is better understood in quantitative terms.This volume presents a comprehensive review of these and other features of the rain forest ecosystem structure, and the ecological processes operating that system. General chapters on abiotic and biotic factors are followed by specific chapters on all major groups of organisms. Prospects for the future are discussed and research needs clearly stated. Also the human exploitation of the system, its effects and its limits are discussed. The book is extensively illustrated by photographs, graphs, and tables, and comprehensive bibliographies follow each chapter. Author, systematic and subject indices complete the book.It is a must for all ecologists, agriculturists, foresters, agronomists, hydrologists, soil scientists, entomologists, human ecologists, nature conservationists, and planners dealing with tropical areas. Biologists and environmentalists will also find the volume of great interest.

Book Description
La revue de ces approches, tant du point de vue de l'evolution des idees que de celle des pratiques de gestion participative dans cinq pays d'Afrique Centrale (Congo Brazzaville, Gabon, Cameroun, Republique Centrafricaine et Guinee Equatoriale) demontre le caractere experimental de ce processus. Le recours aux approches participatives est une reponse aux problemes poses par les orientations classiques de gestion des forets. Il correspondrait aussi, selon plusieurs responsables des administrations des Eaux et Forets, a une obligation de s'adapter au discours des organisations internationales et a un moyen de se premunir contre leurs reactions dans le contexte de l'aide internationale au developpement.

Book Description
Conscients des menaces qui pesent sur leurs ecosystemes forestiers, les pays d'Afrique centrale multiplient les efforts en vue de l'amenagement durable de leurs forets par l'adoption, par exemple, de nouvelles politiques, la revision des lois forestieres, et l'elaboration de programmes forestiers nationaux. Afin de rendre compte des multiples efforts entrepris en matiere d'amenagement forestier depuis une vingtaine d'annees, la FAO a lance une nouvelle initiative intitulee "Recherche d'excellence" visant a identifier et documenter les exemples reussis d'amenagement durable des forets. Ce document decrit ces exemples et fournit des analyses plus approfondies sous forme de 14 etudes de cas. Cette compilation d'informations constitue une source d'inspiration pour les acteurs du secteur forestier et peut donner lieu a une application plus vaste de pratiques de gestion forestiere amelioree et incluant tous les aspects du developpement durable."
