The first concentrates on the dynamic autecological relationships between plant mixtures and the environment.The second part builds upon the mechanistic understanding of plant autecological relationships and describes their patterns and processes across resource gradients that vary with landscape and among different climatic regions.Lastly, the third part provides a protocol for thinking about appropriate silvicultural systems for the particular kind of agroforestry desired.
During the Green Revolution in many developing countries, agroforestry systems tended to reflect modern agricultural systems by their intensive use of fertilizers, pesticides, and site modifications to fit the desired crop. Since the 1980's, agroforestry has learned from traditional indigenous systems to work more closely with the fertility of marginal lands through the use of less intensive cultivation and fallow periods.
True to its title, this volume provides a silvicultural framework for thinking about the design and practice of agroforestry systems. Unlike many general agroforestry books, The Silvicultural Basis for Agroforestry Systems emphasizes research and thoughts from a forestry perspective rather than an agricultural one. Many of the examples used in this reference are based on the ecological theory of forests that concern the competition for resources of plant-plant and plant-animal mixtures. This guide also uses the knowledge gained about the temporal and spatial dynamic and productivity of forests as the basis for silvicultural applications in agroforestry systems.
