Research in tropical forestry is confronted with the task of finding strategies to alleviate pressure on remaining forests, and techniques to enhance forest regeneration and restore abandoned lands, using productive alternatives that can be attractive to local human populations. In addition, sustainable forestry in tropical countries must be supported by adequate policies to promote and maintain specific activities at local and regional scales. Here, a multi-disciplinary approach is presented, to better the understanding of tropical forest ecology, as a necessary step in developing adequate strategies for conservation and management. The authors have long experience in both academic and practical matters related to tropical forest ecology and management.

This proceedings volume has been edited from sixty-nine full text papers of the 132 papers presented to the IUFRO (International Union of Forestry Research Organizations) Conference on Environmental Forest Science, which was jointly organized by IUFRO Division 8, "Forest Environment", and Kyoto University in Kyoto, Japan, on 19-23 October 1998. The International Union of Forestry Research Organizations (IUFRO) is one of the oldest scientific societies. It was founded in 1892 to foster cooperation of research units on forestry. IUFRO consists of 650 research organizations from 100 countries. IUFRO th Division 8 is the latest division, founded at the 20 World Congress in 1995 by subdividing the previous Division 1, "Forest Environment and Silviculture". The objective of this first general Conference of Division 8 is to consider research needs in the 21 sl century for forest environment, and the integration of related fields of sciences to a new concept of environmental forest science.

Human Impacts on Amazonia

The Role of Traditional Ecological Knowledge in Conservation and Development

From the pre-Columbian era to the present, native Amazonians have shaped the land around them, emphasizing utilization, conservation, and sustainability. These priorities stand in stark contrast to colonial and contemporary exploitation of Amazonia by outside interests. With essays from environmental scientists, botanists, and anthropologists, this volume explores the various effects of human development on Amazonia. The contributors argue that by protecting and drawing on local knowledge and values, further environmental ruin can be avoided.

Soil Processes and the Carbon Cycle

World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the Carbon Cycle describes soil processes and their effects on the global carbon cycle while relating soil properties to soil quality and potential and actual carbon reserves in the soil. In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.

Taungya

forest plantations with agriculture in Southeast Asia

As natural forest disappear in tropical and subtropical countries, governments and forest industries are turning to plantations to meet the demand for timber. Taungya forestry has arisen to ameliorate conflicts between foresters who need land for forest plantations and shifting cultivators who need it to plant subsistence crops. Taungya is a system of forest plantations in which peasants are allowed to cultivate crops for the first few years between the seedlings of a forest plantations. Recent modifications to the taungya system include social and economic benefits to participating families. This book describes the history and current practices of taungya, as it has developed in Southeast Asia since its introduction to Burma in the 1860s, and assesses its strengths and weaknesses. It suggests social, economic and technical modifications that may help make taungya a method for improving the sustainability of forestry in developing countries (in Africa and South America as well as Asia), and will interest those concerned with tropical forestry, agroforestry systems and rural development.

Carbon and nutrient dynamics in natural and agricultural tropical ecosystems

Soil fertility is one of the most important fundamental factors regulating yield and productivity in both the agricultural and natural ecosystems of the tropics and therefore its maintainence presents one of the most important challenges to their sustainable use. In particular, declining soil fertility on small-holdings is a serious and increasing problem in Africa and other parts of the world. The product of a symposium held at the University of Zimbabwe in May 1996, this book presents information on the ecological processes and management practices which affect soil fertility and examines methods by which these can be integrated, to obtain economically feasible solutions. It is partly the result of ten years research by the internationally funded Soil Biology and Fertility Project in Zimbabwe, and includes contributions by researchers from other countries in Africa, Asia, Europe and North America. The chapters are grouped into five sections, examining nutrient dynamics in soil, decomposition of crop residues, tree-soil-crop interactions in agroforestry and ecosystem dynamics, and finally considering prospects for the future. This book is essential reading for agronomists, soil scientists and ecologists with an active interest in tropical regions and is an important reference for decision-makers in land use and development in tropical countries. It will also be of interest to students of agronomy, tropical biology and ecology.
