Opis

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.

Recenzje

"This book provides comprehensive analytical accounts of the principles as well as the political implications of agroforestry." ( Abstracts of Public Administration, Development and Environment, 99/00, p.42)
