It provides an analysis of various types of  ecological setttings for agroforestry within temperate  and tropical regions. This book provides a better  understanding of strategies for sustainably growing and  maintaining commercial tree species, relying less on  agrochemical input and mechanical intervention, while  still maintaining acceptable levels of profitability. 0aAgroforestry.1 aFernandes, E.
