Classification of Agro-forestry System
Different types of Agroforestry systems exist in different parts of the world. These systems are highly diverse and complex in character and functions. To evaluate understand and seek to improve them requires their classification into different categories. Several criteria can be used in classifying them, but the most common include the system’s structure, functions, and socio-economic scale of management and ecological spread. According to Nair (1987), Agro-forestry systems can be classified according to following sets of criteria.
1. Structural Basis:
Consider the composition of the components; specially refer including spatial admixture of the woody component, vertical stratification or the component mix and temporal arrangement of different components.
2. Functional Basis:
This is based on the major function or role of the system; mainly of the woody components (This can be productive or protective).
3. Socio-economic Basis:
Consider the level of inputs or management (low input, high input) or intensity/scale or management and commercial goals.
4. Ecological Basis:
Take into account the environmental conditions on the assumption that certain types of systems can be more appropriate for certain ecological conditions.
Classification of Structural Basis Agro-forestry System:
In these systems the type of component and their arrangement are important. On the basis of structure, Agroforestry systems can be grouped into two categories
I. Nature of components
II. Arrangement of components.
I. Nature of Components:
(A) Agri-silvicultural Systems
(B) Silvipastoral Systems
(C) Agro Slivipastoral Systems
(D) Other Systems
II. Arrangement of Components:
(A) Spatial Arrangement
(B) Temporal Arrangement
