Early work concentrated on definitions and system classification, with most working on the triangular model of trees-agriculture-livestock and their interactions. Classifications and groupings of salt-affected soils within the region under consideration are based on the Classification and Diagnostics of Soils of the USSR, 1977[10] and analytical data on . The single most abundant subsystem was 'Mixed home gardens'. Such mitigation is mainly in the sequestration of carbon dioxide (CO 2) which is fixed by plants and incorporated into their biomass (Reicosky & Forcella, 1998; Larcher, 2004), and finally by storing it in the soil. Trade-offs were demonstrated for soils and habitats. The most studied interventions were farmer incentive provision (n = 4, 50%), which refers to any intervention that seeks to motivate farmers to plant trees and practice agroforestry through the provision of incentives (see definitions in Table 2) and farmer capacity development (n = 4, 50%), which refers to efforts focused on enhancing farmer . b) functional basis.

The History of Agroforestry. Table 4: Area of Agroforestry farm . The results of the meta-analysis for impacts on yields indicated that agroforestry interventions overall may lead to a large, positive impact on yield (Hedge's g = 1.16 [−0.35, 2.67] (p = .13)), though there was high heterogeneity in the results (I 2 = 98.99%, τ 2 = 2.94, Q(df = 4) = 370.7). The terms found in the literature are analysed and a classification and terminology by type of agricultural output, by major function, and by distribution of time and space, are proposed. Double layered: the components are grown in two layers, e.g.,tea/coffee under shade tree. On the basis vertical stratification: Single layered: the major components usually grow in one layer or storey, e.g., tree garden. The structural of a system can be defined in terms of its components and the expected role or function of each. are deliberately used on the same land-management units as agricultural crops and/or animals, in some form of spatial arrangement or temporal sequence.
