Agroforestry learn is relevant to constructing tools for the sustainable use of typical renewable assets, evolving to deal with the desires of the arrival century. it's now essential to consolidate the medical earnings now being made in process-oriented learn and to increase a coverage framework to motivate the adoption of sustainable land use practices. Agroforestry performs a tremendous function in retaining woodland assets, decreasing the necessity for deforestation. extra, if `forest' is extensively outlined as tree conceal, agroforestry also will raise the percentage of woody biomass in farming landscapes.
The papers chosen for inclusion in Agroforestry: technology, Policy,and Practice determine agroforestry as an interdisciplinary technology keen on the sensible primary of supporting farmers, woodland dwellers and landscape-level planners to accomplish sustainable meals, gas and trees creation into the twenty first century.

14. Because agroforestry systems use more water than annual cropping systems, they should increase primary productivity. 14. Being tested; depends on competition. 15. There is less competition between tree and crop species that develop canopies at different times. 15. Proven [Dalal, 1974]. 16. Competition for water in agroforestry systems can be reduced by modifying the spatial arrangement of trees. 16. Proven [ICRAF, 1994: 67-73]. Appendix 2 Socioeconomic and ecological guiding principles and hypotheses in agroforestry research, developed by ICRAF Programme 1 staff.

2. Not proven. Too simplistic, since there are no reliable SOM levels related to satisfactory soil fertility. , 1990;] but not for other soils [Rao, in press]. Relevant proof should be in terms of functional SOM pools in relation to system nutrient uptake and overall productivity. 3. Agroforestry systems maintain more favorable soil physical properties than agricultural systems. 3. , 1992; ICRAF, 1994: 85-86]. 4. Nitrogen-fixing trees can substantially augment nitrogen inputs in agroforestry systems.

At the farming systems scale, agroforestry adoption has different impacts for different classes of farmers such as their gender. 5. Farmers are principally interested in the on-farm profitability and risk buffering capacity of agroforestry systems, while society is principally interested in the resilience, sustained productivity and biodiversity of these systems on the watershed and regional scales. 46 Appendix 2. (Continued). 6. Adoption of agroforestry practices usually necessitates policy changes that reconcile individual and social interests and benefits.
