Tropical Agroforestry


Book Description

Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash. Since the recognition of agroforestry as a science, curricula have been developed for agroforestry programs for undergraduate and graduate trainings in Universities. Therefore, there is an urgent need to develop and make available educational material. This textbook strives to provide up-to-date information on tropical agroforestry to serve as educational material in the tropical context. The authoritative textbook of Nair (1993) on agroforestry was published 18 years ago, and before the advent of tree domestication, an important agroforestry practice today. In addition, many other research activities, such as carbon sequestration and integrated pest management, have been included in the agroforestry agenda. This textbook is intended for agroforestry students, teachers, and practitioners.







Soils of Tropical Forest Ecosystems


Book Description

An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics. Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and agroforestry systems as well as ecosystem studies from the dipterocarp forest region of Southeast Asia. Additionally, case studies include work from Guyana, Costa Rica, the Philippines, Malaysia, Australia and Nigeria.




Properties and Management of Soils in the Tropics


Book Description

Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.




Agroforestry Systems in the Tropics


Book Description

This book consolidates the descriptive results of a pantropical project called Agroforestry Systems Inventory (AFSI), undertaken by the International Council for Research in Agroforestry (ICRAF) from 1982 to 1987. Since agroforestry was a relatively new term when the project was initiated, the main objective was to increase the understanding of and provide a state-of the-art information base on existing agroforestry systems. Therefore, the project was designed to systematically collect, collate, synthesize, and dissem inate information on existing agroforestry systems in developing countries. One of the major results of the project, descriptions of existing agroforestry systems, was published as a series of articles in Agroforestry Systems. These system descriptions form the bulk of this book. Other products of the project include a microcomputer database on agroforestry systems, practices and components, and voluminous unpublished reports and records. Perhaps the title of the book is misleading in that the book does not include or cover all existing agroforestry systems in the tropics and geographical regions in the tropics. Additionally, some of the systems described are outside the tropical boul;ldaries of 23. 5" Nand S latitudes. For the purpose of this book, the word tropics is used in a general sense to also include subtropical developing countries that have agro-ecological and socio-economic character istics and land-use problems similar to those of the countries within the geographical limits of the tropical belt.







Forests, Water and People in the Humid Tropics


Book Description

Forests, Water and People in the Humid Tropics is a comprehensive review of the hydrological and physiological functioning of tropical rain forests, the environmental impacts of their disturbance and conversion to other land uses, and optimum strategies for managing them. The book brings together leading specialists in such diverse fields as tropical anthropology and human geography, environmental economics, climatology and meteorology, hydrology, geomorphology, plant and aquatic ecology, forestry and conservation agronomy. The editors have supplemented the individual contributions with invaluable overviews of the main sections and provide key pointers for future research. Specialists will find authenticated detail in chapters written by experts on a whole range of people-water-land use issues, managers and practitioners will learn more about the implications of ongoing and planned forest conversion, while scientists and students will appreciate a unique review of the literature.

Tropical Agroforestry


Book Description

Agroforestry is the cultivation, by farmers, of trees or other woody plants with crops or pasture. Its scientific study is attracting great interest and increasing funding because of its potential to produce sustainable agricultural systems and agroforestry is now included in most university and college courses covering land use subjects. Tropical Agroforestry is the first book that provides an analytical account of the principles, as well as the practices, of agroforestry within the context of the needs of land occupiers and, in so doing, describes the various specialist aspects that are now emerging as part of this discipline. The main objective throughout the book is to present, in a readable way, the underlying functional basis of woody/non-woody plant mixtures and to give a balanced account of how agroforestry can contribute to sustainable production from land. Understanding the biology of multipurpose trees is a key to this.
