Detailed explanation-1: -Socioeconomic Classification of Agroforestry Systems Based on such socioeconomic criteria as scale of production and level of technology input and management, agroforestry systems have been grouped into three categories: Commercial, Intermediate and. Subsistence systems.

Detailed explanation-2: -Alley cropping is a specific practice in which trees or shrubs and agricultural crops are grown in alternate rows (Figure 11.31). The trees are commonly pruned to limit the shading of the agricultural crop. Alley cropping can also contribute to nutrient cycling and erosion control.

Detailed explanation-3: -Agroforestry has its roots in tropical food production systems. In regions with more temperate climates, agroforestry is separated into five distinct but related practices. The five practices are windbreaks, riparian forest buffers, alley cropping, silvopasture and forest farming.

Detailed explanation-4: -The three main components of agroforestry-animals, crops and trees-can be combined in numerous spatial and temporal arrangements and for different functions, creating thus many different kinds of systems.
